Chapter Text

“So as you can see right here,” Kiryuin Satsuki said, with satisfaction evident in her voice, “Mankanshoku no longer has enough exams remaining to receive a passing grade.”

Ryuko stared at her, gritting her teeth, confusion and anger spreading across her cheeks in a crimson rush. When she’d been ‘invited’ to meet with Satsuki in her palatial office, she didn’t know what to expect, but this certainly wasn’t it.
“So?” she asked, putting her hands on her hips, refusing to be intimidated by Satsuki’s tall heels, steely glare, or amused smile.
“So, Honnouji Academy does not allow repeat years. Especially not to idiotic no-stars, regardless of how big their chests are.”
“What!? So you’ll just- just kick her out!? That’s messed up, Kiryuin!” Ryuko shot back, glaring.
“Indeed. I have no place for underachievers who cannot even manage to pass supplementary exams. She’ll be removed from her housing of course. Forced onto the street,” she smiled wolfishly as Ryuko clenched her fists, “She’ll probably have to use those breasts of hers to earn a living~” she added as a final shot.

Ryuko slammed her hands down on the table, her face flushed and her breathing hard. It emphasized her muscular arms and the tanned skin of her chest as Satsuki glanced down her shirt.
“What do you want, Kiryuin?” she asked, reluctantly, her face hard.
“Whatever do you mean?” Satsuki replied, innocently.
“You know what I mean!” she shot back, “You call me here, tell me Mako’s going to be expelled and then what- I just walk away? You want something from me, I’m not stupid!”
“How very perceptive of you, Matoi,” Satsuki said smoothly, placing a single, crisp sheet of paper on the desk between them, “I do want something from you.”

Their eyes met. Ryuko’s furious grey against Satsuki’s implacable blue.
“I want you.” Satsuki said, without a trace of a joke in her voice.
Ryuko’s eyebrows climbed her forehead. She stared, tilting her head.
“You want what?” she asked, incredulous.

In response, Satsuki tapped the paper between them, drawing Ryuko’s attention to the elegant text that was printed upon it. Ryuko glanced down, scanning it- then the scarlet anger in her cheeks faded away into the pale white of shock and surprise.
“…arrive when demanded…obedient when ordered……’handle all of Kiryuin Satsuki’s sexual urges’!? What the fuck is this!?” she crumpled the paper in one fist, waving it at the impassive woman’s face, “This is some fucking joke you’ve got here, Kiryuin!”
“It’s not a joke, Matoi,” she replied smoothly, “Not unless you want your adorable friend to be selling herself in the street to make a living.” Ryuko ground her teeth together, making Satsuki smile.
“I’m not asking much. I just want you to deal with any urges I might have. You’d make a fun toy, although I’d prefer someone a little more elegant.”
“Oh well, apologies for not being more fuckin’ elegant, Kiryuin,” Ryuko rolled her eyes.
“Apology accepted. Now, if you’d be so kind as to stop crumpling the contract and sign it, I can rescind Mankanshoku’s expulsion. Or you can go and tell your friend that you let her lose her home just because you’re too much of a prude.”

Ryuko glared at the woman for a long moment, baring her teeth in a snarl. Disgust roiled in her stomach, but for some shameful reason she could feel her cock beginning to swell and press against her underwear, bulging out slightly. She could have sworn that Satsuki noticed it almost immediately, her wolfish smile widening.
“I’m not repulsive, Matoi, I know that,” her voice turned smooth, silky, almost hypnotic, “You hate me, but you want me too.” Without any resistance, she took the contract from Ryuko’s fist and placed it down, smoothing it out beside the expensive fountain pen, leaning over so that Ryuko could stare right at her swaying chest and impressive cleavage. Ryuko gulped, closing her eyes. She was going crazy.

She was definitely going crazy. Who on earth would sign this?
Then again, did she really have a choice?
She saw for a moment, Mako’s face, as she was told that she had to leave the only home she had.
She grit her teeth, reached down, and signed the paper.

“That’s a good girl,” said Kiryuin Satsuki, immense satisfaction in her smug, superior tone. She slid the contract into one of her desk drawers, looking up and meeting Ryuko’s eyes. Ryuko did her best not to flinch- though disturbingly she felt her dick twitch sharply against her underwear.
“Now…kneel.”
Ryuko gaped, her mouth open. “What?” she asked, stupidly. Satsuki raised one eyebrow.
“You heard me Matoi, kneel. Are you breaking our contract so quickly?”
Ryuko’s mouth made a thin line, but still she took a step back and carefully dropped down onto her knees. To her inner disgust, she felt a stirring in the pit of her stomach, which she tried to smother as fast as she could. Satsuki stepped over to her, the click-clacking of her heels fanning the embers Ryuko was trying to ignore.
“See? You can be obedient when you really try,” Satsuki said teasingly, her voice razor-edged, making Ryuko bite back a sharp retort. She flinched as Satsuki’s hand landed on her head, but all it did was muss her hair, rubbing back and forth in a mocking ‘petting’ motion, as if she were a dog that had just done a trick. Ryuko closed her eyes and tried to ignore the small, nagging voice that said she quite enjoyed having her head patted in this humiliating, subservient way. She shook her head and opened her eyes, pushing that part of her down, deep inside. Her eyes opened just in time to see Satsuki withdraw a little spray bottle from the drawer of her desk and spray it against the inside of her hand.

“What are you-“ she began, but Satsuki ignored her.
“Hold still,” Satsuki instructed, pressing her hand over Ryuko’s mouth and nose even as she tried to lean away in sudden alarm. The hand smelled musky and sickly sweet, and the liquid was warm and slightly sticky against her face. She wriggled, twisting her face from side to side as Satsuki held the hand to her firmly, not allowing her to take a breath untainted by…whatever that concoction was. Already her cheeks were scarlet red, her face flushed, her breathing quickening, coming from her lips in little desperate pants. Her stomach tingled and suffused with heat, and by the time she pushed Satsuki’s hand away so she could gulp at fresh air, her whole body felt too hot, her clothes too tight, her skin too sensitive.
“What did you do!?” Ryuko gasped, fanning herself with one hand, shooting a furious look at Satuki’s unconcerned face, “W-what weird stuff did you just make me inhale!?”
“Nothing serious,” Satsuki said with a slight smile crossing her lips, “Just a little encouragement that the chemistry club develop for me. It's a suggestive-“ her grin widened, “And quite a powerful aphrodisiac.”
Her eyes dragged down Ryuko’s body from her face to her hips. One pristine eyebrow rose.
“Which you’re finding out right about…now.”
Ryuko shuddered, pressing her thighs together, suddenly all too aware that she was hard. Not just erect, but hard as an iron bar, stiff and throbbing against her underwear in a way that was painfully tight and deliciously stimulating. Already she could feel a dampness as copious pre-cum leaked into the taut fabric at the tip of her aching cock. Her hands clutched at her thighs as she fought off the urge to rip her clothes out of the way and give herself the half-dozen or so embarrassingly quick strokes it would take her to climax.
“You’re- you’re fucking sick, Kiryuin!” Ryuko grumbled, unable to properly meet Satsuki’s eyes with such a prodigious tent jutting up shamelessly from her hips.
“And you’re hard, Matoi.” Satsuki spoke with a taunting amusement in her voice, lifting one high-heel clad foot and tapping that barely restrained bulge with the tip. “Take it out. Or you can leave it there and probably finish in your underwear.”

Ryuko gulped and clenched her fists. A bead of sweat dripped down her temple. She held on for almost a full minute, and then she guiltily tugged her skirt up and ripped her damp striped underwear down her thighs until it tangled around her knees. That left her swollen, twitching length jutting up from her hips, a bead of precum slowly trickling down the side of her shaft towards her heavy balls. Satsuki’s eyes widened just marginally, but she made no other motion other than an appreciate hum.
“W-what now?” Ryuko asked, no longer as confident. Her hips burned with lust, and the shivering heat was making her skin feel taut and sensitive, hyperaware of how her clothes hugged her curves, her nipples rock hard against her bra, even the air brushing over her exposed length creating a delicious friction.
“What ever do you mean?” Satsuki asked with absolutely unbelievable innocence in her tone, “Did you want to do something?”
Ryuko grit her teeth together, her nails digging into the inside of her palms.
“I want to jerk off,” she growled, “You- nnn know that.”
Satsuki raised that perfect eyebrow again and tilted her head.
“Ask me nicely, Matoi.” She glanced at her watch with a feigned air of casualness- Ryuko could just see the barest outline of her own bulge outlined against her designer skirt.
“I want to jerk off, please,” Ryuko amended, “Kiryuin.”
Satsuki shook her head, taking a half-step back to perch her backside on the edge of her desk.
“Not good enough, Matoi,” she said, “Do you want me to tear up that contract?”
Ryuko growled at her, words failing as she imagined Mako on the street once more.
“Please, Kiryuin,” she began, “Please let me jerk off…for you.” Her face flushed, but her cock twitched appreciatively. God, she was sick.
“You can use two fingers only,” Satsuki instructed, the corner of her mouth quirking up, “And you may not finish without my permission.”

Ryuko meant to argue, she really did- two fingers was a deliberate humiliation, and the thought of having to beg Kiryuin Satsuki for an orgasm made her growl in frustration. But her body was not in agreement with her mind, and instead her hand gripped her cock frantically, pressing hard with her thumb and forefinger. She began to drag her fingers up and down, mindlessly stimulating her needy dick, her digits quickly slick and sticky with precum that was coated liberally across her shaft.
Kiryuin Satsuki watched her abase herself with a small, smugly satisfied smile on her face, while Ryuko grunted and bit down on her lip in an effort not to immediately disobey and finish in seconds.
“Eyes up here, Matoi,” Satsuki said, her hands lightly pinching the base of her own skirt and lifting it genteelly in an almost-curtsy. An almost-curtsy that revealed her own erection jutting out from her hips and let it hang obscenely in front of Ryuko’s sweating, reddened face. It was hard to think, but two ideas slowly trickled through to the forefront of the transfer student’s brain:

One. That smooth, rigid length draped above her face looked absolutely delicious.

Two. Kiryuin Satsuki had a bigger dick than she did.

Ryuko would not call herself ‘small’, though she didn’t have the ego to call her cock ‘large’ either. She would have settled for ‘average’ or if she was feeling cocky, ‘plenty’. But no, Kiryuin Satsuki had a big fucking cock. It was bizarrely elegant too, with neatly trimmed pubic hair and smooth pale skin that made its throbbing warmth as it pressed against her face even more lewd.
“Remember, we’re here to relieve MY sexual urges,” she continued, as if she didn’t have her cock bouncing against Ryuko’s nose, “Not yours, transfer student.”
Without being instructed further, Ryuko tilted her head up and placed a dainty, explorative kiss along the underside of Satsuki’s shaft, where it lay across her lips. It twitched appreciatively, so she did it again, and again- her lips parting and her tongue flicking out to lap against it as if she were making out with a lover and not pleasuring her worst enemy’s cock while she looked down at her with those cool, triumphant blue eyes.

Satsuki shifted her hips, dragging the warm smoothness of her shaft against Ryuko’s tongue, her voice hitching in her throat as she spoke.
“Take it in your mouth,” she said huskily, nestling the half skin-covered glans of her length against Ryuko’s proffered lips. Ryuko did as she was told, almost without thinking. It felt good, it felt right, taking that cock between her lips, letting it grind slickly along her tongue like a welcome mat. Beneath her display of abject submission, her fingers still gripped and jerked her own needy length back and forth in a sporadic rhythm- quick, eager motions giving way to a tight grip and slow, teasing strokes as she edged herself, holding off her orgasm. She wasn’t sure exactly what Satsuki would do to her if she finished without permission, but she didn’t want to find out.

“That’s it,” Satsuki said, a note of approval in her voice that made Ryuko’s stomach twist, “Good girl.”
Again, Ryuko felt something deep in her, some animal instinct, purr happily at the sickening words. She moaned into Satsuki’s cock, her lips humming against it as pleasure rolled through her hips. Satsuki reached down and ran her hand casually through Ryuko’s hair. There was no affection in the gesture- it felt like a hair-dresser inspecting the growth, only Satsuki was looking for a hand-hold. She found it, and used it as leverage to begin slowly fucking Ryuko’s mouth to her own pace and satisfaction. There was no other word for it, as Ryuko, definitely inexperienced in having a cock in her mouth, became less of an active participant in the sexual act occurring and more of a bystander- or worse, a toy.

That’s what it felt like, in Ryuko’s mind, as Satsuki let out a stifled little gasp and began to thrust her hips, slowly but surely claiming Ryuko’s mouth as she moved her hips back and forth. It felt like Satsuki wasn’t thinking about her at all. She wasn’t giving Satsuki a blowjob, this wasn’t oral sex.
No, Kiryuin Satsuki was using Ryuko’s mouth to masturbate. She was an outlet for her sexual urges and nothing more. A tool to help her reach orgasm. The thought disturbed her, but still her skin felt hot and tight, everything over-sensitive and too-much. Pre-cum was trickling liberally from her desperate erection, and it was becoming harder and harder to hold back. She gagged as Satsuki thrust too far into her mouth, and she felt the length withdraw slightly, the thrusts becoming shallower.

“Mmh- just- just a little more,” Satsuki said, her normally cool, calm tone gone ragged and breathless as she thrust her hips and held Ryuko’s mouth steady with a hand in her hair, “Just hold on-”
Was Satsuki worried about her? Ryuko thought to herself. That had almost sounded like an apology. That would be unthinkable for Satsuki normally, but perhaps once you allowed someone to suck your cock you became a little more personal. Ryuko wouldn’t know. Besides all she could think about now was finishing, the pressure in her balls becoming more and more intense, almost painful as she crested the wave of another edge.
Satsuki’s hips sped up, fucking her mouth with short, shallow thrusts. Ryuko wiggled her tongue against the underside of Satsuki’s glans experimentally, and was rewarded with a stifled moan. So she did it again, winding her tongue around the length violating her. It was a little intoxicating, being able to make the mighty Kiryuin Satsuki make noises like that. The next moan she got was even louder, barely stifled at all, and she grinned internally with triumph until Satsuki gasped-

“A-Ah, that’s it, I’m going to cum, Matoi!”

She barely had a chance to register the words and for her lust-drunk brain to realize where that cum was going to go before the first hot, surprisingly thick rope of it erupted into her mouth, practically hitting the back of her throat. She gagged, trying to pull back in shock and surprise, but Kiryuin Satsuki was making low, womanly moans, and now the grip in her hair was two handed and iron-hard. She fucked her load into Ryuko’s mouth, the smooth shaft throbbing rhythmically and pulsing as it unloaded more and more ejaculate into a limited space. Ryuko gulped, swallowed half a mouthful, then spluttered as it began to spill out from around her lips, splattering messily down her chin. The sensation, the humiliation, the realization that Kiryuin Satsuki was cumming in her mouth was so overwhelming that the next thing she knew, Ryuko was climaxing too, forgetting all about permission and abusing her poor swollen cock with two fingers as fast as she could. Her vision whited out and she felt herself unloading, spraying the hardest, strongest orgasm of her life uselessly onto the floor of Satsuki’s office. She moaned helplessly around Satsuki’s cock, spilling more of her load, but Satsuki’s thrusts slowed and finally stopped until her cock withdrew, half-erect, from her mouth to hang before her.

They stood (and knelt) there, gasping, panting, shuddering with the aftershocks of the two best orgasms of their lives. Satsuki looked down at her, eyes a little unfocused, a little less cool than usual.
“Well done, Ryu- I mean, Matoi,” she said, letting go of her hair and leaning back so she could rest her hips against her desk, “That’s what I meant by relieving me.”
Ryuko coughed, the feeling of Satsuki’s spunk coating her mouth and tongue intensely humiliating in the afterglow of her orgasm. Shame filled her belly, and she readied herself to get rid of it, when-
“Don’t you dare spit.”
Kiryuin Satsuki’s voice was cold and hard, and so were the fingers she used to pinch Ryuko’s cheeks, forcefully closing her mouth.
“You swallow what I give you to swallow, Matoi,” she insisted, “It’s only polite.”
Ryuko’s face burned with hatred and with shame, but she did as she was told. She had no choice, really, with those fingers gripping her so tightly. Besides, she thought, Satsuki’s taste was not so unpleasant, just thick and cloying. Just one more unpleasant thing to do. So she tilted her head back and swallowed the slick, sticky mouthful, feeling it burn warmly down her throat. She shivered, her cock twitching drunkenly at her hips. Oh no, she thought, don’t tell me I’m into that too…

“Good girl,” came the reply from Satsuki, sending yet another shudder through her.
“S-So we’re done?” Ryuko coughed, trying to regain her mental footing, “Mako can stay?”
“We’re done,” said Satsuki, then as Ryuko relaxed, “For today, I mean. Tomorrow is another story.”
Ryuko’s heart sank in her chest. Another day of this? A week? More? For how long? At the same time, her traitorous cock began to harden again. It wanted more of this, even if she didn’t. Satsuki glanced down, raising an eyebrow at her.
“I see that you didn’t listen to my instruction about needing permission,” she said, amusement in her tone. Ryuko flushed.
“It was an accident!” she shot back, embarrassed. Satsuki chuckled.
“Well, I can’t blame you,” she replied, then amended, “At least not for that. But you got some on my shoe. Clean it up, please.”

Ryuko glanced down. It was true- among the messy ropes of her clear-white jizz, one strand had found its was to splatter messily against Kiryuin Satsuki’s left high heel. She looked back up, expression quizzical.
“Sure, you got a tissue?” she asked, naively.
“I do not.”
“Then how am I meant to-” she began, snapping her mouth shut suddenly. “You’re joking, right?”
“I am not.” Satsuki proffered her defaced shoe. “Use your mouth.”
“I’m NOT going to-” Ryuko began, but Satsuki was already speaking, her tone didactic.
“’Obedient when ordered’ I believe the contract says.” Satsuki smiled sweetly. “Unless you’re reneging after all this?”

Ryuko glared at her, her cheeks slowly burning back to hot pink, then crimson red.
“I hate you,” she growled. Satsuki’s laugh was musical, and sent a bolt of mingled lust and shame through Ryuko’s whole body.
“That is permitted,” she purred, “Disobedience is not.”
Their stare continued for what felt like an eternity, and then Ryuko glanced away, her eyes flicking downwards in a shameful admission of defeat. Slowly, she dipped her head down towards the shoe, her lips parting. Her tongue slid forward.

“Good girl,” Satsuki murmured, approvingly.

Chapter Text

After a break of a day or two, the first two weeks of their new arrangement was relatively simple. She would be pulled out of class upon occasion just to suck Satsuki’s cock, the girl fucking her mouth in a business-like manner and then forcing her to hold the thick spunk in her mouth, swallowing only when Ryuko herself was permitted to come- two fingers around her cock, spilling her load uselessly onto the floor.

This time though it was different. Satsuki let her into her office as she normally did, but this time her motions were rougher, more brusque. Ryuko moved with Satsuki’s grip on her arm, but as she moved to kneel before Satsuki’s desk (a motion she was becoming all too accustomed to recently), the woman gave her a harsh tug, sending her stumbling.

“Ow, what the hell?” Ryuko spat, her hackles rising. Satsuki shoved her roughly up against the side of the table, her face stoic even if her actions were not.
“Shut up,” she almost growled, “Hands on the desk, Matoi.”
Ryuko did as she was told.
“Good. Arch your back.” 
Ryuko arched, noticing the way the motion forced her hips and backside outwards. Satsuki’s hand slapped firmly against the inside of one of her thighs.
“Good girl. Spread your legs.” Satsuki said simply. Ryuko’s eyebrows rose.
“You’re not going to-” she began.
“I didn’t ask you for your opinion.” Satsuki’s voice was ice cold, furious- though not at her, Ryuko was fairly sure. That didn’t mean it didn’t hurt when Satsuki’s hand smacked against her other thigh, forcing her to spread her legs wider, exposing her ass beneath her painfully short school skirt.

Ryuko had been thinking this might happen for a while now. Actually, Ryuko had been tormented by lewd dreams of this happening, or something like it, ever since their first meeting. She had kind of hoped Satsuki would be satisfied with her mouth alone, but clearly the novelty was wearing off having Ryuko kneeling in front of her desk with a cock down her throat. 

Satsuki’s fingers glided up her outer thighs, sliding up under her striped underwear and lifting them down to her knees. Ryuko flushed, even though Satsuki couldn’t see her face. It was humiliating, knowing she was completely exposed and bottomless to her worst enemy. If someone were to walk into the office now, they would get an eyeful of Ryuko’s bare behind bent over Satsuki’s desk- and her furiously stiff cock dangling helplessly between her thighs. 

There was a quiet snap, the sound of a bottle opening, and then a few moments later something soft, gentle, and fucking ice cold drizzled slowly down her backside. She yelped, reaching back with one hand in protest. That drew another smack, this time to her rear.

“Hands on the desk, Matoi, it’s just lubricant.” Satsuki chided.
“It’s fucking freezing is what it is!” Ryuko complained, “It feels like-a-ahhh-”
Her complaint trailed off as Satsuki, without warning, slid one slick finger two knuckles deep into her rear passage. Ryuko bit her lip, emotions warring inside her as Satsuki stirred her up, slickly sliding that finger back and forth. It felt so full! This was one finger- how the hell was Satsuki’s stupidly big cock going to feel? Her own dick twitched in answer, and she flushed a deeper crimson. Damn it, Satsuki having a bigger dick than her was never going to be easy to accept.

A few moments later, there was a twinge of discomfort that made Ryuko gasp, as Satsuki wordlessly added a second finger, thrusting them back and forth rhythmically inside her. Ryuko concentrated on breathing. It wasn’t unpleasant, that was the problem. It was new, and humiliating, and felt…kinda good, actually. And she hated that. Hated that Satsuki was getting what she wanted, hated that she enjoyed it, even a little.
“You’re very quiet today, Matoi.” Satsuki teased coolly, “I don’t even have my length in your mouth.”
“F-Fuck you-” Ryuko grunted, her legs twitching as Satsuki hit a particularly nice spot.
“No, I’m going to fuck you ,” Satsuki replied instantly, “And from the sounds you’re trying so hard not to make, I think you’re going to enjoy yourself.”
“W-what?” Ryuko gasped, “I’m not-”
“Oh please, you twitch every time I curl my fingers.”
Just to prove it, she did so, making a downwards arch of her fingers as she thrusted. Ryuko bit her lip, but still, a mewling, desperate sound slithered from her mouth.
By the time Ryuko felt as if she were getting used to it, the fingers slid from her backside with a gentle tug, leaving her feeling slick and ready for something more. And from the sounds of it, that was what Satsuki was going to give her, as she squirted lube more liberally over her own endowment. 

“You’re ready enough, I think.” Satsuki said, one hand squeezing a handful of Ryuko’s plump backside, the other guiding herself forward. Ryuko felt the blunt head of Satsuki’s cock grind against her slick hole, and her breathing caught in her throat.
“Kiryuiin-” she began,
“Relax, Matoi, I’ll go slow. I don’t intend to break you.”
Satsuki’s voice was quiet and calm, but Ryuko detected- or maybe hoped, she heard a note of concern there. Every so often Satsuki would do something that showed that, in a minute way, she considered Ryuko more than just a relief for her sexual tension. Ryuko clung to those moments like a drowning man, and tried not to think too hard about why.
“O-Okay…” she muttered, hating how helplessly submissive her voice sounded.

But then Satsuki’s cock was pushing its way inside her and god it was so much bigger than her fingers! Even with the lube, it felt as if she were being filled to the brim, inch after inch sliding into her slowly, achingly full, hard as iron and burning hot, filling her depths with a humiliating heat. 
“That’s it, you’re so tight for me- so hot, so ready…” Satsuki complimented, her voice filling the silence punctuated only by Ryuko’s ragged breathing, soothing her as if she were a scared animal.
“Good girl- such a good girl, taking my cock so deep…” 
Ryuko whined out a breath, her own erect cock twitching so hard it slapped against her stomach for a moment. She loved being called a ‘good girl’, and hated that she loved it.

Finally she felt the soft, smooth tautness of Satsuki’s hips against her backside, and realized that it was done.
“There we go, Matoi.” Satsuki said, a smug note of triumph in her voice, “All the way inside you now.” She leaned forward, one arm sliding round to pull Ryuko towards her.
“Every inch.” she whispered into her ear. Ryuko shuddered, clenching around the invader in her backside. Satsuki dragged her hips back slowly, letting Ryuko feel the thick length sliding out of her, then thrust suddenly back in, hitting her deep once more.
She couldn’t help it. Ryuko’s mouth opened, without her consent, and let out a surprisingly girlish moan, a definite sound of obscene pleasure. Her hand flew up from the desk and slapped over her lips a moment later, but it was too late. Behind her, Satsuki laughed musically, her eyebrows rising. 

“What was that Matoi?” she asked, teasing.
“N-Nothing-” Ryuko shot back, flushed, her breathing ragged.
“Liar. I knew you were going to love it.” Satsuki fisted a hand into Ryuko’s hair and tugged her back and to the side a little so they could meet eyes. “You’ve got a mouth on you but you’re such a bottom .”
“I am not a fucking bott-ahh~!” Ryuko tried to argue, but Satsuki rolled her hips again, faster this time, and drove another girlish moan out of her mouth.
“Oh please, you’ve craved this from the moment you first saw me, even if you didn’t admit it to yourself. And now here you are, bent over my desk like a good little bitch, my cock hilted in your obedient backside.”

Ryuko wanted to argue, but she couldn’t- she had wanted it- even before she knew Satsuki had something to fuck her with. After that first, humiliating defeat, it was over for her. She knew she’d come crawling back to lose over and over again. Still, neither of them wanted her to fold without a fight, so she arched her back and shoved her hips back onto Satsuki’s own, making her grunt.
“J-Just hurry up, I don’t have all day,” said Ryuko, “At least when you’re in my mouth you cum fast.”
“Oh is that how we’re going to play it?” Satsuki asked, imperiously, “Like if I don’t keep moving my hips like this, you’re not going to spray your seed over my desk out of that pathetic thing you call a penis?” Another thrust, another strangled noise from Ryuko.
“I-It’s not pathetic!” Ryuko hissed, her face red.
“Of course it’s not,” Satsuki said sarcastically, “Care to make a wager on that, Matoi?”
“You’re on!” Ryuko spat instantly. Like an idiot. Moments later, she clenched her eyes shut and berated herself for being so easily baited.
“Very well then, if I climax before you do, then I will give you any request you like.”
“Seriously!?” Ryuko asked, her voice incredulous, “You know I could just force you to leave Mako alone and end this whole game?”
“Yes, but you wouldn’t, you enjoy it too much.” Satsuki said, a smug smile on her face. “But consider it a show of my confidence. Perhaps you could use your request to reverse our positions?”

Ryuko could not talk for a moment then, her brain barraged by scenes of Satsuki on her knees, choking herself on Ryuko’s cock, those icy blue eyes staring up at her. Satsuki bent over her own desk, moaning as Ryuko ploughed into her from behind. She shuddered. 

“A-And if you win, and I cum first?” she asked, to distract herself more than anything.
“Then you’ll spend the rest of our coitus praising me and begging me to finish inside you,” Satsuki said simply, gripping her backside in both hands and giving her a short, rough thrust to drag another gasp out of her throat.
Ryuko couldn’t think any more. That sounded…incredible. Humiliating. Awful, in the worst possible way. Her cock twitched and pulsed, hard as iron beneath her, betraying how she truly felt, the conflict between her pride and her lust raging in the pit of her stomach. She gulped, swallowing her doubts as she replied.
“Y-you’re on, Kiryuiin.”

To her surprise, Satsuki did not immediately begin jackhammering her. No, she was more subtle than that. She worked her way up to it, enjoying the experience of fucking Ryuko’s backside for the first time, savoring it, sure in her self-control. She began taking her slow and deep, bottoming out with each thrust so that their hips met with a gentle slapping sound. Ryuko bent over and took it, panting raggedly, brain and body awash with this new pleasure. 

After what felt like an eternity, Satsuki began to speed up, taking her with quicker, businesslike strokes, thrusting shallowly into her, faster and faster. Ryuko quickly found that she could no longer control her voice, and the room filled with her gasps, moans, and humiliated sounds of pleasure- though if she listened hard, she could hear Satsuki grunting with exertion and perhaps pleasure, also. It was good but it wasn’t good enough- Ryuko was willing to admit that having Satsuki fuck her was deeply humiliating in a kind of nice way, but she wasn’t going to climax from this, not with her cock bouncing helplessly after each thrust, desperately seeking stimulation. It seemed Satsuki was too good to give a reach around, so Ryuko remained confident that she was going to win their little bet.

“Alright, time to finish this off,” Satsuki announced suddenly, breaking Ryuko’s concentration. She thrust forward suddenly, angling herself so that she ground the tip and shaft of her cock against some point inside Ryuko that sent stars spinning around her head. She moaned, her mouth dropping open and letting out a groan of startled pleasure. What was THAT?
“W-what, wait-” Ryuko grunted, but Satsuki hit it again and made her gasp.
“Of course you don’t know what a prostate is, why am I surprised?” Satsuki said to herself, “Well, you’re finding out now.”
Another thrust, another moan. And now Satsuki was speeding up, their hips meeting SLAP SLAP SLAP- against one another while pleasure shot like lightning through her hips.
“The prostate is a pleasure spot during anal intercourse,” Satsuki explained patiently, as if Ryuko were in a health class and not being rammed over a desk with a cock in her ass. She leaned over, gripping Ryuko’s shoulder and using it as leverage for her to keep slamming her hips forward.
“We might as well call it a bitch button,” she hissed into Ryuko’s ear, over her moans and pleas, “Because I can push it to make you my bitch .”

“Nnghh, n-no, I can’t- Wait- Satsukiii!” Ryuko mewled, trying to rise but losing her balance, slumping onto the desk under Satsuki’s relentless assault, that fat cock hammering her slick insides, coring her out, grinding against that sweet spot inside her until she felt like she was cumming with every stroke.
“That’s it, good girl,” Satsuki gasped, hands groping Ryuko’s body for leverage as she took her to the edge, “Do what we both want and lose for me.”
“N-No, I- I won’t lose-” Ryuko stammered, but she knew it was a lie, she could feel it happening.
“Yes you will. Do it, pig.” Satsuki snapped, taking her faster, “You’re going to lose all over my desk without even touching your decorative prick. You’re going to lose- say it! ”
Ryuko’s back arched, her whole body pulsing in pleasure, throbbing each time that cock slammed into her, like a new heartbeat. She couldn’t think, couldn’t fight, couldn’t win-
“I-I’m going to lose!” she wailed. Satsuki slapped her ass, hard.
“Again!”
“I’m g-gonna lose-” SMACK-
“Again! Louder, pig!”
“I’m gonna lose! I lose! I lose I lose I lose- oh fuck, fuck, Sats, I’m cumming, I’m gonna-”
Satsuki pushed her almost flat to the desk, slamming her cock in to the hilt and holding it there, grinding it against that spot inside her that turned into an utter bitch. Satsuki’s bitch.
“Lose for me, Matoi,” she demanded. And Matoi did. Her cock flexed, throbbing with heat as, unprompted by hand or mouth, it recklessly spurted its load across the desk, pulsing and twitching violently. If Ryuko had cum hard the first time they were together, it was infinetessimal compared to how hard she was coming now, from her ass, from Satsuki’s cock. Her vision was whited out, and distantly she could hear herself squealing and moaning, gasping and writhing on the table as she painted it with her useless seed.

Time passed then. How much of it, Ryuko didn’t know, but when she came to, Satsuki was stroking her hips slowly, running her fingers over her sore backside, making small thrusts of her cock that drew little noises of involuntary pleasure from Ryuko’s lips. 
“There you see?” Satsuki said smoothly, “I win.”
“Y-you…” she whined, “You cheat- o-oh fuck.”
“Nonsense,” Satsuki dismissed the complaint with a wave of her hand, “Now you’re going to honor your deal and beg me to finish inside you.”
Ryuko flushed, hands gripping the desk. The loss was more embarrassing than being fucked in the ass over a table, and the knowledge that the ‘reward’ for her humiliating defeat was more humiliation stung her. Still, a deal was a deal. So she gulped and-
“Please, finish inside me.” she said simply. Satsuki snorted.
“No. I want you to beg.” She shifted her hips, rocking back and forth slowly, making Ryuko grunt and gasp with pleasure- mingled with a little oversensitive pain now.
“Please, Kiryuiin, finish inside me-” she said, more earnestly now, “I want you to finish in me.”
“Better, but still no,” Satsuki said, enjoying herself immensely. “Reach back and show me what you want.” Ryuko growled under her breath, but did as she was told. This time, she grabbed her own backside, parting her cheeks further to show Satsuki how her cock looked inside her.
“Please, Kiryuiin, please-” She began to rock her hips, taking over the work, giving Satsuki a show, “Please cum inside me, I want to feel it. I need it-”
Satsuki grunted, muffling her sounds of pleasure, but clearly she was feeling it. Ryuko swore under her breath, drawing on her limited knowledge of porn and the erotica she read under the covers to fill out her vocabulary.
“Please, Satsuki, your big cock feel so good, I need to feel you cum in me-” she stuttered, the words sounding patently fake to her own ears, even if Satsuki seemed to appreciate it. But still she didn’t climax. Ryuko racked her brains. There had to be something that she could say. Something true, or at least believable- oh.

Ryuko bounced her backside off Satsuki’s hips, rolling her body once, twice, three times, then gasped-
“Please Kiryuiin, please cum in your good girl!” she wailed.
Satsuki hissed in surprise, and then her hands were on Ryuko’s hips, hilting herself and quivering with exertion. There was the feeling of sudden heat, intense and vaguely pleasant, deep inside her, and Satsuki’s length twitched rhythmically as she climaxed wordlessly in Ryuko’s ass. Slowly, Satsuki’s body draped over Ryuko’s, pinning her to the table, both of them panting, sweating, limbs tangled like lovers. 

It was two minutes later, and Satsuki was dressed again. Ryuko took comfort in the fact that her hair was slightly mussed and she’d had to change her tights before she could look professional again. Ryuko meanwhile, felt shockingly empty. Satsuki held out her underwear in one hand, offering it to her.
“Thanks-” she began, “Wait, what do I do about the-” About the load of cum in my ass , she didn’t say, but Satsuki knew what she meant.
“For now, nothing. I want you to put that underwear on, get dressed, and go back to class.” Satsuki’s voice was smooth, calm, possessive.
“W-what? Why?” Ryuko gaped.
“Because I want to think of you walking around this school with my cum inside you. I want you to know that while you’re here, attending this school, that is your true role.” Satsuki took a step, then another, until she was almost on top of Ryuko again.
“To be my sexual relief. To be my cum dump .” she mouthed, the lewd words sounding elegant in her polished tone.

Suddenly, Ryuko snatched the underwear out of Satsuki’s hands and whirled on her feet, tugging it on as fast as she can. Partly because she was angry, but partly because her cock had reacted viscerally to hearing Kiryuin Satsuki dirty talking and was now trying desperately to attain a full erection again. She dressed quickly, trying (and failing) not to think about the fact that Satsuki’s creampie was still deep inside her, marking her as something owned, something claimed. And she tried not to examine too deeply why the thought of Satsuki claiming her felt vaguely…good.
“Are we done here?” Ryuko asked sharply, trying to force her blush away.
Satsuki nodded simply, reaching out and tweaking the corner of Ryuko’s blouse into the correct position. 
“We are. For now.”
“Then I’m leaving.” Ryuko said, making for the exit.
“Matoi?”
“What?” Ryuko turned, hand on the door.
“You were a good girl today.” Satsuki said simply, the corner of her mouth twitching into a smile. Ryuko’s face flushed all over again, and she turned and fled the room.

Chapter Text

To make one thing clear, Ryuko hadn’t hoped to get fucked some more. Sure, the experience had been…enjoyable, but it wasn’t as if she wanted to spend every lunch time getting bent over Satsuki’s desk and railed. Still, she’d kind of sort of hoped it would happen at least once more.

What actually happened was a return to the status quo. Satsuki would call her in, use her mouth, and make her leave. Of course that made it sound more business-like than it actually was. For example, right now Satsuki had her hands pinned above her head while she squatted, and Ryuko’s chin dripped with drool as Satsuki rocked her hips back and forth urgently. She’d gotten a lot better at sucking cock in the last few weeks, as you might expect when you’re forced to do it every day, and now she made only a few choking, gagging noises as Satsuki made almost full use of Ryuko’s throat, her heavy balls slapping against that drool splattered chin. 

“Mmph, that’s it, good girl- almost-” Satsuki purred under her breath, her iron-hard grip on Ryuko’s wrists intensifying. Ryuko shuddered, her tongue lapping against the underside of Satsuki’s dick in the way she knew she liked best, urging her towards climax. She still felt a little shiver, heat in her belly whenever Satsuki called her a good girl, and she still hated that it got such a visceral reaction out of her. Ryuko was not a ‘good girl’ and even if she was, the last person she wanted to hear that from was Kiryuin ‘facefucks me for a hobby’ Satsuki.

Satsuki made a strangled moan low in her throat, and thrust suddenly, grinding her hips into Ryuko’s face, and Ryuko’s head into the office wall. 

“Nnghh fuck- take it, take my cum-” Satsuki growled possessively. Ryuko didn’t want to admit it, but that was the Satsuki she liked the most- urgent, primal, lost in how good it felt to orgasm. She swallowed dutifully, trying not to choke as Satsuki pumped her load almost directly down her throat, before pulling out and stepping away.

Ryuko stumbled to her feet, wiping her mouth. Her head was sore from the pressure, she had bruises on her wrists, and her throat felt dry and unpleasant. And worst of all, she was horny as all hell.

“Are we done here?” she asked, annoyance seeping into her tone. Satsuki raised an eyebrow, imperiously.

“Is there a problem, Matoi?”

Ryuko rolled her eyes.

“Noooooo, I love getting called in her to suck your stupid dick every day. It’s the best .”

“Are you dissatisfied with our current arrangement?” Satsuki asked, rearranging her uniform to hide her dishevelled state, “Or are you just missing being bent over my desk?”

Ryuko flushed as a wave of heat ran up her neck and onto her cheeks.

“I didn’t say that, I just-”

“Haven’t been fucked in two weeks?” Satsuki interrupted teasingly. Her flush deepend.

“Are you doing it on purpose?!” Ryuko snarled, “Because that’s-”

“I wanted to see how long it would take before you asked me to do it again.” said Satsuki, a small, smug smile crossing her face, “Now I have my answer. If it helps, I thought you’d snap far sooner.”

Ryuko was speechless. She paced back and forth, trying several times to start a sentence before trailing off wordlessly. Finally, she settled for-

“ Fuck you, Kiryuin.”

“That’s not happening,” Satsuki said glibly. 

“You know what I mean!”

“Oh relax. Here, I’ll make you a deal.” Satsuki closed the distance between them, backing Ryuko up against a wall. She couldn’t help it, Ryuko never could match the overwhelming pressure Satsuki gave off, a kind of mixture of power and sexuality that intoxicated her, made her brain just shut off.

“If you come to my room tonight, I’ll do all the things you’ve been wishing I’d do to you.”

Ryuko nodded jerkily, too embarrassed to deny wishing any such thing.

“Or you can not come, and I can continue relieving myself using your excellent mouth.” Satsuki finished, tapping her finger lightly against Ryuko’s bottom lip. Ryuko shuddered, her stomach twisting uncomfortably as pride and shame mingled in her guts.

Before she could formulate an answer that satisfied either of those feelings, the bell rang, and she used the distraction to slip past Satsuki and flee. Satsuki remained where she was, still smiling that wolfish little smile. Tonight was going to be interesting , she thought to herself.

The student council president’s rooms were easy to find, but Ryuko still glanced around in paranoia as she paced towards them. She felt…vaguely dirty, doing this, as if she were some kind of escort or late-night booty call. Which, she thought to herself, she basically was. Satsuki had called her over tonight to…well, to fuck her. She gulped, swallowing roughly, and reached down to adjust herself down there. She’d been rock hard from the moment she’d showered herself clean in preparation for tonight, and walking here without it becoming obvious she was popping a fat hard-on was not the easiest thing she’d ever done. 

It bothered her how much she’d prepared, too. She’d showered, trimmed, shaved, even- she flushed with embarrassment, even ‘prepared’ herself back there too. All so she could step into Kiryuin Satsuki’s actual bedroom and get fucked . This was supposed to be a non-consensual arrangement- or at least blackmail! She wasn’t supposed to dress herself up like a fucking date night to go get railed by the woman who was threatening to kick her best friend out of school. And yet she’d done exactly that. She tried to tell herself that she was doing this for Mako, to keep herself on Satsuki’s good side, but her words were hollow. She didn’t have to do this, and she definitely didn’t have to be rock hard in the shower thinking about it. 

Thankfully, Satsuki’s door appeared to cut off her spiraling train of thought. She glanced left and right, but the corridor was deserted, as well it should be since no-one (not even Ryuko) was supposed to be here. She took a deep breath, swept her short hair back with one hand, and then rapped sharply on the door. It opened after a moment, and Ryuko’s mouth dropped open. She made a dumb-founded noise, her eyes sliding up and down the figure standing in the light of the doorway.

Kiryuin Satsuki was always uncomfortably hot. The tall, regal bearing. The angular face with the long, sleek black hair and luxurious eyebrows. The pouty mouth that proclaimed itself infinitely superior to you and made its disdain immediately evident. The long, tapering legs, taut with muscle. The subtle swell of hips, and bust. A backside that just did not quit. And, more recently, the thick, arching length of her smooth, pale cock that did as much as her smug expression to claim innate superiority over any challenger.

All of this was on display, clad in thin blue lace and sheer silk. The long black hair was still damp from the shower, and the arches of her curves were accented with see-through flowers of blue lace lingerie, half-cup bra clinging desperately to her full breasts. There were stockings, also blue, also see-through, sheathing her muscular legs and giving them an ethereal look. And finally there was a lacy blue thong that did absolutely nothing to conceal Kiryuin Satsuki’s ridiculously disproportionate length jutting out hard from her hips. Ryuko stared for a long, long moment, frozen as all the blood in her body seemed to concentrate in her dick, throbbing in her pants. She was intensely aware of how lacking her own casual clothes were, and it took a surprisingly strong effort of will not to go down onto her knees and apologize.

Satsuki stared at her the whole time she hesitated, one eyebrow raised, her lips curved into a smug grin, evidently satisfied with her reception. Finally, Ryuko managed-

“D-do you always answer the door like this?”

Satsuki rolled her eyes and blew out a snort.

“Who else was it going to be, Matoi?”

Ryuko blushed. “Right. Sorry. Can I-” she made a gesture.

“I don’t know…” Satsuki pretended to muse, “Maybe I’ll just make you kneel right here…”

“If you put my mouth on your cock, I’m gonna bite-” Ryuko began, interrupted by a peal of laughter from Satsuki. She waved a hand, taking a step back.

“I’m kidding.” She leaned in as Ryuko stepped past her into the room, “ We both know you’re not here for that. ” All Ryuko could do was shiver as Satsuki’s voice buzzed against her ear. 

Satsuki’s room was simple and elegant, dominated by the large four-poster bed, sheets in luxurious white. There were no personal touches, no photos, no trinkets or momentos. Ryuko felt a pang of sadness for a moment, glancing around the room, at least until Satsuki’s palm slapped sharply against her backside.

“You’re over-dressed, Matoi.” She said as she stepped past her, moving to half-lean, half-sit against the side of the bed. Ryuko ducked her head and reached down for her shirt.

“Wait-” Satsuki snapped, her tone so used to being obeyed that Ryuko stopped almost instinctively. She looked up, meeting Satsuki’s warm blue eyes and not liking the mischief she saw there. “Take them off slowly. Give me a show, Matoi.” she insisted.

“I am not doing a striptease for you, Kiryuin.” Ryuko shot back instantly. Satsuki quirked a brow, but said nothing. Ryuko glared at her defiantly, but she made no move to act. She simply leaned against the bed, her lingerie clad body inviting Ryuko to be worthy of possessing it. Ryuko noticed that she was still hard- clearly these kinds of power games were as intoxicating to Satsuki as they were to Ryuko. She tilted her head back and sighed, reaching down for her t-shirt’s hem.

“I can’t believe you’re going to make me do this.” she said, disgustedly. Satsuki coughed.

“Excuse me, I’m not making you do it.” said Satsuki, a pointed look on her face, “I simply gave you an order, and left it to you to decide whether or not to be a good girl. And yes-” she added, “I did notice you shiver every time I call you that.”

Ryuko briefly considered dying of embarrassment, but instead masked her humiliation by tugging her shirt over her head, tossing it away with one hand. That left her in a rather plain striped bra and her pants. She closed her eyes, willing herself to pretend Satsuki wasn’t there, and she was stripping to empty air instead. But she could feel the heated gaze of the woman on her as she trailed one hand slowly down her body, between her breasts and over her stomach. She popped her hip out to one side as she caught the button of her pants between two fingers and tugged it open, exposing the top of her striped panties. She heard Satsuki’s small, sharp intake of breath, and was emboldened, despite the humiliation. The knowledge that Satsuki wanted her to do this because she liked Ryuko’s body, desired Ryuko’s body, made it somehow easier. It gave her power, and Ryuko liked that. So she turned, hands sliding down her sides and over her hips, hooking into her pants and sliding them down as she bent over. That gave Satsuki a long look at her plump backside and muscular thighs which she audibly appreciated with another small noise of enjoyment.

The bra came off next- from behind, so that she could hide her breasts with one arm. Ryuko was forced to open her eyes at this point, as she glanced over her shoulder to gauge the stripping’s impact. The usual stoic Kiryuiin Satsuki was staring intently at her, her blue eyes sparkling with lust. Shockingly, one of her hands was casually at her hips, idly holding her length. That ignited a fire in Ryuko’s belly, and she turned, trying to make her motions smooth and sexy in a way she was totally unused to. She cupped her breasts in her own hands, squeezing them, pressing them together as she bent over. She was sure her actions were amateurish, clumsy at best, but Satsuki seemed enthralled. Finally, her hands reached her underwear and tugged them slowly off, exposing every inch of her body. As her waistband snapped down over her cock, it sprang up, so hard that it slapped against her own hips, exposing just how much Ryuko was unwillingly enjoying herself. She tossed the panties aside, putting her hands on her hips, her face flushed, her heart pounding.

“Happy?” she asked Satsuki venomously. Satsuki smirked.

“Very,” she purred, “Good girl. Now get on the bed.”

Ryuko did as she was told (which she was not a fan of, in general), because the burning lust in the pit of her stomach told her that if she could just hold out and not die of embarrassment in the next few minutes, she’d get what she wanted. She scaled the side of the ridiculously big bed, crawling up onto all fours, trying to ignore the face that she was putting absolutely everything on display for Satsuki’s appreciative gaze.

“No, not like that-” Satsuki said, catching her by the hip and tugging sharply. Ryuko made a yelping sound of protest, and they fell in a pile of tangled limbs. There was the sound of flesh on flesh as the two of them wrestled for dominance, momentarily back on the battlefield, that ended with Satsuki once again on top, pinning Ryuko’s wrists over her head, leaving them both panting and a bare few inches apart. Ryuko was all too aware of Satsuki’s triumphant eyes, and the pleasant, slightly embarrassing way she could feel the girl’s erection grinding gently against her own. 

“Like this-” she said, “I want to see your face while I take you.”

What do you say to that? Ryuko thought, turning her scalding cheeks to one side and making a disgruntled murmur that might have been a protest, acquiescence, or both.

That said, Satsuki made no move to take her, instead simply pushing her hips forward, letting her feel their erections slowly grinding against one another. She moved a hand downward, taking both of their lengths in her firm grip and stroking them. 

“Look at that, Matoi~” she said, lining their members up as if comparing them.

Ryuko glanced down, sure she couldn’t be any more humiliated. She was wrong, as she saw in this position exactly how much bigger Satsuki was than her.

“Great-” she mumbled, “Awesome.” Satsuki chuckled under her breath.

“Who’s bigger, Matoi?”
“What?” she asked, “What do you mean-”

“I want you to look down there and tell me who has the bigger cock, Matoi Ryuko~” Satsuki teased, using her full name with deliberate cruelty. Ryuko grit her teeth.

“You do.” she admitted. It wasn’t like she could argue the case when that superior length was sliding intoxicatingly into her own, almost bullying it back against her hips.

“Don’t forget it.” Satsuki said simply, releasing Ryuko’s member and letting it slap down against her stomach. Then she was angling her hips, drawing them back to slide between- There was a moment of fumbling as things lined up, hips wriggling and back arching, until finally Satsuki clicked her tongue in frustration and pulled Ryuko’s hips up bodily. Ryuko let out a gasp before she could stifle it, the strong, possessive motion igniting a fire in her belly, and then…

It was easier the second time, Satsuki’s well lubricated length pushing into her, opening her up. Ryuko let her head fall back, her eyes closing as she let out an unreserved sound of pleasure that drew another chuckle form Satsuki’s lips. It was all sensation- Ryuko kept her eyes closed so she didn’t have to admit it was Satsuki taking her like this, like a lover would, face-to-face. If she kept her eyes closed it was just anonymous hands gripping hard onto her hips, a muscled body pushing up against her backside, and an anonymous cock sliding back and forth, hitting her prostate with every thrust, forcefully dragging moans of pleasure from between her teeth. God, she'd missed this.

She heard Satsuki grunt with exertion, felt her ankles hanging off her shoulders. Dimly, through the pleasure, she could feel her lower stomach was wet, sticky with constantly leaking pre-cum. Just as that realization hit, Satsuki’s hand cupping her hardness and began to stroke in short, determined pumps that drove her quickly towards the edge. 

“Nnghh w-wait, I’m already close-” Ryuko said, panicking. Satsuki snorted.

“Shut up and make a mess for me, Matoi.” Ryuko couldn’t help but oblige her, the humiliating tone pushing her over the edge. Her eyes squeezed tight, she could only feel the force of her ejaculation painting her chest and stomach with her own seed, her body shuddering and jerking randomly as she gasped, groaned, and swore her way through a full body orgasm. 

Ryuko was about ready to slump back onto the bed and take a five hour nap, but clearly Satsuki wasn’t finished with her. Still she wasn’t expecting her to keep stroking, and finally her eyes were forced open as oversensitive pleasure mingled with pain in her post-orgasmic state. Her hands flew down to grab at Satsuki’s wrists, her thighs trembling with every thrust of Satsuki’s hips and every pump of Satsuki’s fist. 

“W-wait, fuck, stop- I already came!” Ryuko mewled, trying to force Satsuki’s hand away from her cock, but it was like trying to bend a solid iron bar. Satsuki rolled her eyes.

“Who would have guessed that someone with such an attitude would be a total quickshot,” she said mockingly, her voice remarkably even aside from a little heavy breathing. “I’m not finished yet, Matoi, so you’ll just have to deal with being premature.”

“You were the one stroking m-my- ahhghhh~!” Ryuko bit off her complaint as another wave of pleasure swept through her body, Satsuki’s hips slapping more forcefully into her own, their bodies getting closer and closer until Satsuki was all the way on top of her, thrusting hard, their breasts mashed together, Satsuki’s hand wedged between their flesh, using her cum as lube to stroke her. 

Ryuko was groaning like an animal now, feral and fierce, her hands finally free to clutch at Satsuki’s back, leaving long pink-and-red scratches, nails digging in. It only seemed to spur Satsuki on, fucking her with long, hard strokes that made Ryuko see stars and bury her teeth into Satsuki’s shoulder.

“Please!” she heard herself wail, “God, Satsuki, please cum, cum in me, cum in me, cum in me-” She could hear the telltale noises of Satsuki’s pleasure; the hitch in her breath, the almost growling moan deep in her throat that told Ryuko that she was close. Ryuko fisted two hands into Satsuki’s long black hair and tugged on it, drawing another groan from her lips. “C’mon Sats, give it to me, I want it-” Ryuko was gone now, her embarrassment forgotten in an orgy of pleasure and the frenetic motions of their joined bodies, so she didn’t even flinch as she begged abjectly for Satsuki’s release, meeting her eyes from inches away.

“C’mon, that’s it, g-give it me, I’ve been good, I’ve earned it-” Ryuko growled, rocking her hips up to meet Satsuki’s ardent thrusts, “Give your good girl what she wants and-”

There was a beat as Satsuki bottomed out inside her and she felt that thick length inside her begin to twitch. It was perfect, it was everything she wanted, and Ryuko felt her second orgasm approaching on the brink. She just needed a little more-

Without a thought in her head, she used the leverage of her fists in Satsuki’s hair to drag her down the last few inches until their lips met, grinding together hotly into what was unmistakably a sloppy, urgent kiss. Satsuki made a startled, mewling sound into her mouth and Ryuko felt her begin to cum, rocking her hips and groaning into the kiss. For her part, Ryuko clung to Satsuki like a drowning woman, seeing stars as her second release erupted over Satsuki’s pumping fist. The kiss dragged on through their mingled climaxes, ending only when the need for air became too great and Ryuko fell back onto the bed, her vision going blank.

When Ryuko awoke, it was to the sensation of the softest, most comfortable bed ever beneath her body, and to the warm, slightly damp heat of a cloth being run over her hips and stomach. She blinked her eyes open and saw Satsuki, still lingerie clad, cleaning her up with a look on her face she’d never seen before. That look vanished the moment Satsuki noticed she was awake, being replaced by the usual smug, post-nut Satsuki smirk that she loved to hate. She found it increasingly difficult to be upset about anything Satsuki did- though that was obviously because getting upset after two orgasms required energy she just did not have right now. Her eyes focused on how much more relaxed Kiryuin Satsuki looked after she got off, smoothing the harsh edges from her expression. Her gaze slide down, lingering on the curve of Satsuki’s lips. 

Oh.

Ryuko felt her face begin to heat up, her blood flushing to her cheeks. Satsuki looked at her, raising an eyebrow.

Oh fuck, that happened. That actually happened.

Satsuki seemed to notice the direction of her gaze, and then something truly shocking happened. Satsuki’s own cheeks began to slowly turn pink.

“I know we have an arrangement, Matoi,” she began, her words more hesitant than normal, “but I would appreciate it if you didn’t kiss me without warning.” Ryuko looked at her for a long moment and then responded in the only manner she could.

“You’re blushing,” she pointed out, childishly.

“No I am not !” Satsuki said icily, tossing the damp cloth aside and folding her arms beneath her breasts. Ryuko chuckled tiredly. 

“Yes you are, Kiryuin, your cheeks are bright pink.” 

“They’re pink because I’m tired-”

“They’re pink because you find it less embarrassing to fuck me than to get a kiss-”

“Stop talking right now, Matoi. ” Satsuki’s voice echoed in the quiet room, and Ryuko’s mouth snapped shut. She shrugged theatrically.

“Sure. Fine. Whatever you say.”

Satsuki rolled her eyes and slid down onto the bed, laying back beside Ryuko, with a respectable distance between them. Clearly she wasn’t going for a post-coital cuddle. That was a-okay with Ryuko.

“You can leave whenever you like, Matoi.” she said lightly. Ryuko snorted out a laugh.

“Yeah right, I can’t even feel my legs. I’m sleeping here.”

Satsuki blew out a breath in frustration, but didn’t argue. Before long, Ryuko’s breath evened out, and she slid easily back into slumber, flat out on her back.

Satsuki didn’t fall asleep for a long time. Idly, she gazed at Ryuko’s sleeping face. Defenseless. Satisfied.

“You need to put a stop to this.” Satsuki murmured to herself. “This is getting out of hand.” This was supposed to be a way to relieve her stress and keep Matoi under control. Instead it seemed only to slowly embolden her- Satsuki realized she was touching her lips, and snatched her hand away as if burned. She rolled over and tried to put Matoi Ryuko out of her mind, settling down to sleep. It took a long time to arrive.

Chapter Text

~~Interlude: Time Well Spent.~~

Ryuko panted, her bare chest rising and falling, the expensive wood of Satsuki’s student council desk digging into her back. She lay naked atop it, her arms slack and wrists tied to the legs of the table, while each of her ankles was tied to her thighs with a clever harness. She hadn’t asked where Satsuki had produced the dark red rope from (hopefully not Gamagoori, she thought), but the sensation of it wrapped tightly around her skin added a new frisson of desire in her stomach and made her feel very, very vulnerable.

Satsuki’s fingers fluttered over her chest, tweaking a nipple as they passed, forcing a little gasp from her lips. Elegant fingernails traced down her stomach ticklishly, just firmly enough to feel like scratches. Ryuko whined under her breath, wriggling in her bonds as Satsuki’s fingers ran slowly up the bound girl’s erect cock, flicking the tip and making it sway as she chuckled. Ryuko’s source of frustration was less due to the teasing of Satsuki’s fingers however, and more to do with the tight little red ribbon tied around the base of her member. It put pressure right where it needed to in order for her length to feel needy and swollen and at the same time just tightly enough that despite fifteen minutes of teasing, she still couldn’t come . 

“S- Kiryuin, please-” she heard herself pant, “I-I’ve been good, let me out this fucking thing!”

Satsuki simply chuckled, then stepped close. She was naked too, her beauty plain to see. Ryuko flinched as Satsuki did what she’d done ever time Ryuko had complained since they began- taking her impressive length in one hand and just slapping it rudely into Ryuko’s face, across her cheeks and lips hard enough to hurt. It was deeply humiliating, and each smack of Satsuki’s cock on her face sent her deeper into a little submissive well of pleasure and neediness that made her thoughts fuzzy and her cheeks red with more than just bruises. 

“You said I could do ‘anything I want to you’ during our lunch break,” Satsuki said, taking malicious pleasure in quoting her while rubbing the swollen glans of her cock against Ryuko’s lips. She lapped at it obediently- a sign of just how deeply the frustration was getting to her. Finally she broke off and grumbled,

“T-Thought you’d just fuck me…”

“Then you thought wrong.” Satsuki corrected her, “I have more elegant and varied tastes than you, Matoi Ryuko. The height of submission is not being bent over a desk for a five minute fuck.”

“Then what is it!?” Ryuko spat back, “And it’s not like you fucking complained!”

Satsuki reached over and this time it was her hand that smacked sharply against the head of Ryuko’s swollen member, dragging a pitiful cry from her lips.

“ Obedience .” Came the leaden, iron-hard response. “Now, try and keep quiet for the next three minutes and I’ll give you a reward. Can you manage that?”

“...yes…” Ryuko’s voice shook with exertion, but she managed a ragged nod. 

She wriggled, eyes fluttering open and closed- she wasn’t sure which was worse; if she looked , she could see Kiryuin Satsuki’s naked body, her elegant hands wrapping around Ryuko’s smooth sack, caressing the orbs there as if weighing them, her fingertips tracing the delicate veins of her twitching erection; but when she closed her eyes she didn’t know where Satsuki was going next, and each touch and stroke and tease was not nearly as awful as the heart-stopping pause between them, the agony of not knowing what was to come. Satsuki began to stroke her in earnest- long, sloppy strokes with a palmful of lubricant that made each slick motion agonisingly good. Ryuko bit down on her lip until she could taste blood, desperately trying to contain the feminine, desperate sounds rising in her throat. How much time had passed? A minute? More? Less ?

She glanced down and saw that Satsuki was mirroring the motions she was performing on Ryuko on her own, larger member, adding, perhaps to the competition. That nearly made her gasp in arousal- despite her hatred, her libido could happily watch Kiryuin Satsuki jerking herself off for hours. Then Satsuki leaned down, taking her hand away and cupping it around the base of Ryuko’s cock, where the ribbon was tied. The other hand slid down across her sweaty backside and slid to press firmly against her tight, eager hole. Ryuko clenched her eyes shut for a moment to brace herself, but Satsuki’s thumb failed to push inside of her, simply content to massage and tease her sensitive ring while she controlled her cock with the other hand. 

Then Satsuki lowered her head, and Ryuko’s breath caught in her throat. Satsuki’s face came closer and closer to her length, until she could feel the heat of her breath against it. Was she really going to- Satsuki’s bright blue eyes flicked up to meet Ryuko’s gaze, amusement twinkling there. She pursed her lips and blew a stream of cool air over Ryuko’s swollen tip, making her arch her back. She opened her mouth, letting her tongue hang out lewdly so that saliva could drip…drip…drip onto Ryuko’s member. The thought of being enveloped in Satsuki’s mouth even for a second was so enrapturing that before she knew what she was doing, Ryuko spoke-

“ Fuck, please!” she whispered. 

Satsuki rose, her hands pulling away, straightening up just as Ryuko realized she’d been fooled.

“Oh fuck you , Kiryuin!” she growled. 

“You’re so easy.” Satsuki laughed. Ryuko flushed scarlet.

“Just let me cum! I need to cum, Kiryuin, I need it- I’ve played your stupid games, I’ve been- I’ve mostly been obedient! T-Take this stupid thing off me and let me finish!”

Satsuki chuckled again, and Ryuko couldn’t help notice that one of her hands had returned to her waist, stroking her member in a decidedly less teasing way than she’d been stroking Ryuko. 

“Oh, one of us is going to finish, but I don’t think it’s going to be you, Matoi.” Satsuki sighed, her breath hitching in her throat. Ryuko stared, her mouth dry. Unbidden, she swallowed hard and her mouth opened without her consent and blurted-

“F-Finish on my face.”

There was a pause, and Satsuki stared at her, her hand slowing on her cock. 

“Pardon me?” Satsuki asked, raising an eyebrow. Her mouth spread in a slow smile, as if she’d heard a particularly dumb student give a brilliant answer. 

Ryuko’s face was on fire but she persevered.

“I-I can tell you’re close. I want you to finish on me…” she explained, lamely.

“Why?” Satsuki asked, her lips quirking up.

“Maybe I just don’t wanna swallow,” Ryuko shot back, but Satsuki shook her head.

“Nice try.” She stepped closer, hips swaying as she moved over to Ryuko’s head where it lay half hanging off the desk, her cock hypnotically bobbing in her grasp as she stroked herself, “You want me to cum on your face because we both know that you love to lose . You love to be humiliated. You love being an object for me to vent my urges on.”

“S-Shut up and finish. I a-asked you to cum, not monologue.”

“Say it.” Satsuki interrupted, slapping Ryuko’s cheek with her cock again, a meaty ~smack~ sound echoing in the room. “Tell me why you want me to cum on your face, Matoi.”

Ryuko wanted to brat some more, wanted to deny and refuse and hesitate, but she was so turned on, so on the edge from all the teasing, so deep in subspace from the constant, degrading talk that she just began to beg, voice husky with need.

“P-please, Kiryuin, I want you to finish on my face. I want you to humiliate me- I need it. I want to feel it splash over my face. I w-want it to mark me, own me.”

Satsuki leaned close, hand blurring as she pleasured herself, pushing herself to the edge.

“Don’t stop,” she growled, making that little noise of pleasure that shivered down Ryuko’s spine and told the submissive part of herself that she was being A Good Girl.

“Cum, please, do it-” she wriggled in her bonds, opening her mouth, hanging her tongue out, “Fuck me up, show everyone I’m your cum-target bitch -” 

Satsuki grunted and then Ryuko had just enough time to close her eyes before the first thick rope of Satsuki’s cum splashed against her forehead, nose, and cheek. It was shockingly hot, and she made a slutty little ‘Ahh~’ as she kept her mouth open for the next pulse to splatter against. Satsuki’s orgasms were as high-spec as the rest of her body and before long stroke after stroke of jizz was splashing against her face, mouth, and tongue

About half-way through Satsuki’s orgasm, one of her hands drifted down and did two things. One- she tugged the bow of the ribbon tying Ryuko’s cock. Two- she lifted her hand and smacked Ryuko’s cock hard enough to make it slap off her own hips with a wet smacking sound. Ryuko gasped and bucked her hips, her bound body unable to give herself any relief as her orgasm swept through her body and she came, hands free, ruining herself onto her own stomach and abs with a mewling series of shuddering moans. 

When Ryuko could think clearly, she was still tied to the table. Her body was drenched in sweat, and her tummy was soaked in her own release. Her face was hot and sticky, and one eye was plastered shut with Satsuki’s still-warm facial. Her mouth was around Satsuki’s cock, which slid back and forth across her lips and tongue, unconsciously allowing her to clean the spent member off. Satsuki glanced down at her, smugly smiling.

“Good girl~” she teased, “Turns out you can be obedient after all.”

Ryuko grunted.

“Get these fucking ropes off me, lunch ended ten minutes ago.”

Satsuki’s eyes flew to the clock and an entirely unrestrained curse flew from her lips.

It took her ten more minutes to undo all the knots, leaving her twenty minutes late for a student council meeting, sweaty, and obviously suspicious. Still, she mused, thinking back to the photos she had taken of Ryuko’s sweaty, blissed out, cum-splattered face, it was time well spent.

Chapter Text

Satsuki was normally extremely strict in her routines; she would rise early with the dawn, every day like clockwork. Today however, she woke bleary eyed and taut. As she raised a hand to knuckle the sleep from her eyes, a gasp forced its way from her mouth. Her lower half was burning hot, her hips sheathed in slick, soft heat. She tilted her head down to see Ryuko's face in her lap, her dark fringe and red streak hiding her eyes as she determinedly bobbed her head up and down on Satsuki's rock hard morning wood. Satsuki opened her mouth to ask Matoi what exactly she thought she was doing, but only a moan came out as Ryuko's tongue swirled expertly around her glans. With a shock she realized that she was already close, her balls tight, heat and tension rising in her hips- Ryuko must have been practising her fellatio while Satsuki was still deep asleep. Unable to speak, unable even really to think, Satsuki could do little but hold on for dear life, fisting a hand in Ryuko's hair and rolling her hips urgently as Ryuko's mouth brought her to climax.

"M-matoi-" Satsuki grunted, off-balance, her usual suaveness not yet operational this early in the morning, "I'm-,"

Ryuko hummed approvingly, the sensation buzzing through Satsuki's hips, pushing her over the edge. Ryuko's lips slid up Satsuki's shaft, retreating to suckle firmly at her glans while her fingers replaced her mouth on the shaft, fist pumping rhythmically with each trembling thrust of Satsuki's hips. Satsuki could hear, above her own strangled growls and involuntary noises of pleasure the erotic sounds of Ryuko's lips, tongue, and throat working as she swallowed Satsuki's morning release as if it were a precious commodity not to be wasted. When did she get so good at this- , Satsuki thought to herself as she shuddered her way through her climax, body shivering with prickling heat. Her head fell back and she lay there, panting as if she had just run a marathon, fuzzy sleep mingled with the languid pleasure running through her hips.

Finally she managed to summon the energy to speak.

"What on earth was that, Matoi? What do you think you’re doing?”

Ryuko looked at her, one eyebrow raised as if to say 'Duh?' Then she met Satsuki's eyes and deliberately swallowed whatever was left in her mouth. Satsuki gulped too, involuntarily, then corrected herself.

“I mean, why did you do it?”

Ryuko shrugged easily, her cheeks pink, her expression feigned indifference.

“I dunno. Maybe because you’d make me do it later anyway? Maybe because it’s easier when you’re not humping my face like a dog?”

It was Satsuki’s turn to go red.

“I do not-”

"Maybe I’m just hoping you're just less of a bitch when you're waking up to getting your dick sucked in the morning." Ryuko licked her lips, a little theatrically, Satsuki thought. Still, her half-hard member twitched violently at her hips. “I thought you’d be pleased.”

“...I am, I suppose.” Satsuki said, shaking her head in disbelief. 

Ryuko glanced down. Smirked.

“I can tell.”

Ryuko’s back was pressed hard to the slick stone of Satsuki’s expansive bathroom, her thighs wrapped around Satsuki’s plunging hips, her arms around her shoulders, clinging onto her for dear life. The water poured down onto them, running over Satsuki’s arms as they held Ryuko forcefully against the wall, fingers digging into the plump muscle of her buttocks. Ryuko had her head back, cockiness driven out of her by the power of Satsuki’s assault, her hair plastered to her scalp, her mouth opening and closing in desperate gasps as the dark haired girl drove into her, the SLAP SLAP SLAP echoing over the soft sound of the shower.

“F-Fuck, god, Sats-” she whined, every sentence faltering on her lips, such was the sheer power in Satsuki’s hips as she slammed into her, her cock hitting deeper than she felt like she’d ever done before, “S-So deep- fuck -”

Satsuki growled, her teeth sinking into Ryuko’s exposed neck, her feet digging into the floor of the bathroom as she kept them both upright, pinning Ryuko to the wall and skewering her face-to-face on her newly revived erection. Their bodies mashed together, slippery breasts and achingly hard nipples grinding slickly as they writhed frantically. Satsuki dipped her head, bit the curve of Ryuko’s breast to draw another whining sound of pained pleasure from her lips. 

“Am I less of a bitch now?” Satsuki hissed at the red-haired girl, slamming into her harder and harder, mercilessly driving herself towards her own climax, caring naught for how good Ryuko felt. That only made it more embarrassing that she was most of the way towards cumming herself, Ryuko thought, her mouth gaping but no words coming out. 

“Well!?” Satsuki asked again, “I’m waiting, Matoi!”

“Y-Yes!” she wailed, “God, please cum, please- I need-”

That was enough for Satsuki. She buried herself inside the aching tightness of Ryuko’s hot little hole and slammed her against the bathroom wall as if trying to grind her to dust against it. She felt Ryuko tighten down on her in sheer response as she finished inside her, grunting and gasping against the girl’s neck as she fucked her load into her. 

When the last drops of her climax had been milked from her by Ryuko’s eager backside, Satsuki deigned to lower her to the floor, both of their legs shaking- her’s from exertion, Ryuko’s from pleasure. She disentangled herself from the girl quickly, turning to rinse herself off under the spray of the shower, ignoring Ryuko as if she were a masturbatory aid that she was finished using. Why that made Ryuko feel so hot and flushed was not something either of them truly understood- though Satsuki enjoyed explaining her theories on it in humiliating detail. 

She was ready to walk from the shower and get dried off when a hand closed on her shoulder, its grip desperate. She turned her head, raising one thick eyebrow in question. Ryuko stared at her, face flushed, legs shaking, body half hunched over. It made the thick, blunt length of her twitching erection look almost comical on her frame. It was surely aching with need, and Satsuki found her mouth curving up into a smile. 

“What ever is the matter, Matoi?” she asked innocently. Ryuko glared at her.

“I- Well, I- I didn’t-” she began with anger, but it boiled away as she stumbled over the words. Satsuki had discovered quite quickly that Ryuko could only talk lewdly if she was in the midst of coitus, her shame burning away under Satsuki’s thrusting. Any time outside of those occasions, and she reacted like a middle schooler reading a particularly difficult book out loud. 

“Spit it out,” Satsuki said mercilessly, “Didn’t what?”

“Didn’t…y’know…” she gestured downwards helplessly, “G-get to finish.”

Satsuki let that hang in the air, eyeing her in amusement as Ryuko turned steadily more red.

“Well, I did.” Satsuki said, the corner of her mouth quirking up into a smug smile.

“Y-yeah, but- that’s not fair!” came Ryuko’s predictable response. Satsuki shook her head. Honestly, sometimes this was too easy. 

“Nothing about our arrangement is fair , Matoi Ryuko. You’re here to be used, not for your own pleasure. If you have a problem with your libido, you’re free to use your hand to resolve it like the horny monkey you are.”

“I am not a horny monkey-”

“That is exactly what you are.”

“Fuck you, Kiryuin! ”

“I’ve told you, that’s not happening.” She took another step towards the door.

“...please.” Satsuki paused, not quite sure she’d heard it. She turned.
“I beg your pardon?”

“...I said please . Please help me finish.”

Satsuki’s eyes sparkled as she let out a low chuckle. 

“What was that? Matoi Ryuko begging for a reward without me asking? You really are being a good girl today.”

Ryuko’s face couldn’t get any more red, but now she could barely meet Satsuki’s eyes, her embarrassment was so great. It didn’t seem to be affecting her intense looking erection however.

“P-Please, Kiryuin. I need- I’m gonna go crazy.”

“Turn around.” That was all she said. All she needed to say. Ryuko spun on her heel, turning to face the wall, placing her hands on the stone. Satsuki’s body slid up against hers, slick and wet, smooth skin against flushed flesh. Satsuki’s breasts squished pleasantly against her back, their heights putting the dominant woman at the perfect level to press her lips hotly to the curve of Ryuko’s ear. Their bodies melded together as if they were made to be fit together- one completing the other. Ryuko gasped when Satsuki’s silken hand closed around her member and began to stroke- long, firm motions of her wrist that drove into Ryuko’s hips and then back, twisting slickly around her glans. It was clear that she intended this to last as short a time as possible, and Ryuko was more than okay with that, her voice letting out wanton little cries while the shower once again echoed with the sound of skin slapping against skin. 

“Go on, let it out,” Satsuki purred, “Waste it onto the floor for me.”

“S-Satsuki~” she whined, “C-Close, I’m close-”
“Of course you are, pig, that’s natural,” she teased, whispering the humiliating words that she knew would spur Ryuko onto greater heights of pleasure, “You’re going to whine and pant and spurt your pathetic semen onto the floor while saying my name and thanking me for the privilege. Now stop making me wait! ”

Her hand sped up, grip tightening and then Ryuko was grunting, trying to shake her hips like a dog. Satsuki held her firm, once again pinning them together as she brutally brought her to climax with one hand, Ryuko curling her hands into fists against the wall.

“C-Cumming, Satsuki, S-Satsuki thank you-” she panted, hot lightning flashing behind her eyes and in her hips as she felt the surging tense-and-release sweep through her, “F-Fuck-”

Satsuki slowed her strokes, but didn’t stop until Ryuko dropped a hand from the wall to catch her wrist, silently begging her to relent. She did so, and Ryuko stood, panting, her hands on her thighs, catching her breath. She looked down, watching as the shower washed away her release, and felt a shameful stab of pleasure in her chest at the sight. 

By the time she thought of anything to say to Satsuki, the girl was long gone. 

When Ryuko had cleaned herself up- and holy shit, that was embarrassing , she made it back to Satsuki’s room, holding a fluffy white towel awkwardly in front of her that was small enough that it was probably meant for Satsuki’s hair. Satsuki was waiting for her, dressed already, drawing a brush through her long, elegant locks, looking distinctly relaxed. 

Ryuko spared her a look, then swept her eyes back and forth around the bed, to where her clothes had ended up after her impromptu (and deeply humiliating) striptease the night before. They were nowhere to be found, but then Satsuki looked like the kind of person who folded other people’s clothes, so she turned back to the woman and asked.

“Hey, Kiryuin, where are my clothes? I gotta get dressed if we’re gonna be on time for class.”

“I didn’t know you cared about being on time, Matoi.” Satsuki teased. Ryuko shrugged.

“I don’t. But you do, and I’m guessing you’re gonna kick me out as you leave.”

“True.”

“So- that brings me back to ‘where are my clothes’.”

“Oh, I had Soroi wash them and send them back to your house.”

For a moment, Ryuko was sure she had heard wrong. She tilted her head, like a dog hearing an unfamiliar sound.

“You did what ?” Satsuki’s mouth curved into a grin.

“I have something better for you to wear, as it happens.”

She nodded, and Ryuko suddenly became aware of a small, paper folded package sitting on the neatly made bed. Her imagination briefly played out a thousand humiliating scenarios about what was inside- a micro-bikini, bondage ties, a leash and collar, a leotard, no, maybe a slutty skirt?

By the time her hands had taken the carefully folded paper in her hands and opened it, it was getting hard to breathe normally.

“This better not be a-” she began, but then she saw what it was, and her face twisted. “You have got to be kidding.”

“Not at all,” Satsuki murmured, stepping closer, “You’ve been a good girl, haven’t you?”

“T-that’s got nothing to do with- with this. ” Ryuko gestured at the outfit. Satsuki snorted.
“Of course it does. It’s a reward for good behavior- keep it up, Matoi.”

Ryuko’s hands reached down and lifted the outfit up, turning round to brandish it at Satsuki, angrily.

“ This ,” she growled, “is a one-star uniform!”

“How observant of you.” said Satsuki. Like a bitch.

“I am not wearing a one-star uniform. I didn’t wear a NO-star uniform. I am not wearing a f-fucking uniform like you fucking own me .”

She knew when the words passed her lips that she’d made a mistake. Satsuki’s eyes met hers, held them. Ryuko glared back, internally demanding her cheeks not to flush and heat, and cursing them when they ignored her. Finally, after a silence that seemed to stretch for hours, Satsuki spoke, saying exactly what she knew Kiryuin Fucking Satsuki was going to say.

“ Don’t I? ”

“I’m not wearing it!” Ryuko spat, dodging the question she definitely didn’t want to answer right now, “Not in a million fucking years!”

Satsuki took a step forward- a quick one, then another, and then her outstretched finger was thumping Ryuko in the chest, pinning the uniform to her body. 

“You have two choices, Matoi,” she said, her tone ice-cold and iron-hard, “You can do the walk of shame from my room all the way back down the city streets in that towel- if I even let you keep it- like the well-used bitch you are.”

Ryuko gulped, her skin prickling up as she imagined how humiliating that would be- the shame burning hot in her cheeks as she made the long walk down into the city back to Mako’s house with a towel only big enough to cover half of her body, exposing herself and letting everyone know exactly what a nearly nude young woman had been up to the night before.

“O-Or?” she whispered, her voice hoarse, her throat dry as the desert.

“Or,” Satsuki said, lifting her finger from Ryuko’s chest, and flicking it upwards to tap against the tip of the girl’s nose, “You can accept your promotion like a good girl.”

“Wow, Ryuko! You got promoted!?” Mako asked, staring wide at the girl shifting uncomfortably in the new, well-starched uniform that tugged and pinched as if trying to mold her into the same shape all the other one-star boys and girls seemed to resemble. 

“I- I guess,” she mumbled, “I’m not keeping it!”

“Why are you blushing, Ryuko-chan~?”

“I’m not!”

Chapter Text

It took Ryuko four whole days to make Satsuki angry. 

She’d expected it to be quicker, after she’d done the climb all the way up to the school just to skip for two days, walking round and deliberately picking fights with club members and the Disciplinary Team. She’d mimed snoring during Satsuki’s boring speeches, and she’d even broken into Satsuki’s council chamber and left her rude messages on Honnouji Academy letter-head paper. None of these antics got a response, which pissed her off even more.

In her mind, her strategy was simple; get rid of this unwelcome one-star promotion by acting out and breaking rules until Satsuki was forced to take it away and demote her. Or, as her libido told her every morning as she woke up throbbing against her futon, Satsuki would get angry enough to really punish her, which was sick, and wrong, and also deeply arousing in a way that made her need a cold shower before she put that damned uniform on in the morning.  

After three long days of mischief with nothing to show for it except frustration and an aching libido, Ryuko knew she had to do something bigger. Bolder. 

So she waited until Satsuki passed her in one of the broad corridors of Honnouji Academy, her nose upturned, regally ignoring her as-per-usual, and then reached out and -smacked- her palm hard against that muscular, up-tight bottom. Satsuki had made a noise somewhere between a gasp and a snarl, and before she knew what had happened Ryuko was seeing stars and the floor had rushed up to meet her. The last thing she remembered was a furious Satsuki dragging her towards her office by one leg while students stood and stared, whispering furiously about what might have possessed the rebellious transfer student to spank Lady Satsuki. 

When she woke up, Ryuko was in a worryingly familiar location. She was embarrassed to even be able to recognize the grain of the wood of Satsuki’s desk against her cheek, but she was more embarrassed to realize she was tied face down over it, her wrists bound to the legs of the desk, her short one-star uniform skirt flipped up over her hips and her underwear nowhere to be found. She craned her head left and right, hissing at the pain in her neck and her jaw, but Satsuki failed to appear. 

“Lemme guess…” she mumbled though a fat lip and the taste of blood against her teeth, “You’re really mad at me this time~?”

That revealed that Satsuki was behind her, because only Satsuki’s hand could come down that hard directly on her upturned backside with a sharp crack of flesh on flesh that made Ryuko hiss and wriggle in her bonds. 

“A spanking, really?” she taunted, “I’m not a little ki- ah fuck! ” Satsuki’s hand came down again, harder than before, and this time she couldn’t keep her mouth shut. Fire radiated through her hips as Satsuki’s hand rose metronomically up and then back down, smacking hard against Ryuko’s increasingly reddening buttocks until she was having to clench her teeth to stop herself from crying out. This was new- she’d never been spanked before, not in what was clearly a sexual way (with Satsuki’s hand groping and squeezing her sore and tender backside between every strike), and it was both painful and deeply humiliating. 

Which was why she was as hard as a rock, her erection pressing into the desk painfully as Satsuki slapped, spanked, and brutalized her backside from pale pink, to deep crimson. Not that Ryuko could see that, as her restraints kept her prone and helpless over the desk, completely at the mercy of the silent Satsuki standing over her. The fact she hadn’t even said anything was starting to worry her. 

“What-” she panted, “Not gonna lecture me this time?”

Satsuki’s hand froze in mid-air. In a tight, furious voice, she replied, “I won’t waste words on those who won’t listen, Matoi. You’ve made your point.”

“My point is f-fuck you.”

“Your point is that you’re too stupid to be taught normally, and too stubborn to know a good deal when you see one. If you insist on acting like a pig in human clothing, I will treat you like one.”

“I’m not a pig-”

“Then don’t squeal.” Satsuki’s hand came down with the force of her full arm, and the sound was louder, clearer than before, the pain more sharp and visceral, echoing through her hips and making her cock twitch uselessly against the desk. With a growing sense of horror, Ryuko realized that until this moment Satsuki had been holding back. Her backside already felt like it was on fire, she didn’t know how she was going to last if Satsuki was going to-

Satsuki did. 

It lasted a long time- how long, Ryuko didn’t know, because she couldn’t hear the ticking of the antique clock over the relentless smacking of Satsuki’s palm against her bottom. Time lost all meaning. Ryuko swayed and slid through the five stages of grief over what felt like hours.

She clenched her teeth, stiffened her body and tried to tough it out, denying Satsuki the pleasure of her reactions.

As noises slipped between her lips, sweat dripping down her face, her backside screaming in oversensitive agony, she changed tack and swore at her, yelling insults and defiance helplessly. Satsuki did not even deign to respond, though whenever a particular jibe landed, Ryuko could feel her hit just a little bit harder.

Finally, she broke.

“S-Satsuki! I’m sorry! Kiryuin please, fuck! ” she wailed, her body juddering against the desk, making it scrape across the floor as she flopped like a fish drowning in air, writhing furiously in her bonds. “I give! I give up! I’m sorry! I’ll be good, I’ll be good! I won’t- ah~! I won’t be bad anymore! Please- Please I can’t-”

“No.” Satsuki’s voice was tight with rage. Her free hand slapped down on the small of Ryuko’s back and pinned her to the desk like that same fish against a chopping board. Evidently the beating had not drained even a fraction of her anger from her. 

SMACK- SMACK- SMACK- SMACK- 

“F-Fuck, ow, ow, ow, please! ” Her voice was desperate. Pathetic. She hated it. But now there was sweat and tears in her eyes, big, ugly sobs that splattered down her cheeks and onto the floor. “I’ll be good! I’ll be a good girl! I’ll be good for you! I’m sorry Kiryuin! I’m sorry, I’m sorry, I’m sorry- I can’t take it, I can’t take it, please- oh god, please-”

She begged for what felt like forever, stopping only to squeal, pig-like, when Satsuki’s brutal spanking thrummed through her body like lightning. Somewhere during her pathetically submissive pleas, possibly when she had to gasp for breath, she realized that the next blow had not yet landed. This threw her, and she choked on a sob, barely daring to hope it was over. Time seemed to freeze except for her ragged breathing and the pattering of her tears down onto the floor, clashing with the slow rhythm of the ticking clock. 

“...S-Sats?” she mumbled, “A-Are…” 

Her voice trailed off as Satsuki’s hand pressed oh-so gently to her left buttock, squeezing and kneading it with strong, muscular fingers. Ryuko hissed in pain as Satsuki tightened her grip and pulled to one side, spreading her openly intimately. 

No way, thought Ryuko, she’s not going to-

She was. Satsuki’s thick, already-slick glans ground fiercely against Ryuko’s exposed backdoor. The inexorable force of Satsuki’s weight leaning forwards pushed and pushed until that muscular little knot spread wide for her and let her in. Ryuko made a whimpering sound as both of Satsuki’s hands fastened around her hips, that fat fucking head popping inside her and filling her up with the promise of more to come. She was exhausted both physically and emotionally and instead of her usual shit-talking and less-than defiant hip motions, all she could do was lie there restrained and let Satsuki take what she wanted. And there was more to come. Inch after iron-hard inch pushing into her, stealing her breath away.

It wasn’t until her mouth let out a whining noise of pain that she realized Satsuki was all the way inside her, her hips grinding like sandpaper against her sore, punished backside. Still, despite the pain and humiliation and exhaustion, she still made a quiet, moaning gasp as Satsuki drew back and began to thrust. She didn’t rush, but neither was she gentle. She treated Ryuko’s sore backside and tight little ass as an onahole to sate her lust and her frustration on, fucking her with long, firm strokes that ending with a grinding wriggle of her hips as if she were seeking to bury herself even deeper inside Ryuko’s quivering, twitching passage. 

If the spanking had taken hours, this felt as if it were merely seconds. All too soon she felt the tell-tale flex of Satsuki’s length inside her, promising an end to the humiliation. She heard the heiress’ breath catch in her throat, a stifled groan as she thrust hard enough to slap her heavy balls up against Ryuko’s own. Without knowing why, or caring about how it sounded, Ryuko’s mouth opened without her consent and spoke.

“P-please, Sats- inside, I need-”

Satsuki wasn’t heartless, though indeed it was unlikely even her iron willpower would have let her hold back so late. She thrust to the hilt, stiffened, her fingers tightening on Ryuko’s hips. There was the muffled sound of her pleasure escaping through the teeth dug into her lower lip, and the blissful heat in Ryuko’s belly that meant Satsuki was finishing inside her. It felt good. It felt right. And she was too done to care about how that made her feel. She didn’t even care that her own erection throbbed urgently beneath her- it felt like it was a million miles away, a faraway concern when compared to how good it felt to have Kiryuin Satsuki climax inside her. 

When she could think again, Satsuki had pulled out of her, leaving her feeling exposed and shockingly empty, as if something crucial was missing. That was bad enough, but then she felt Satsuki’s hand, that had spent so long hurting her, softly press against her hair. She moved her hand in a slow, gentle motion. Petting her. Stroking her. Grazing her fingernails across Ryuko’s scalp. 

“Good girl…” Satsuki said reverentially, “That’s a good girl.”

Ryuko couldn’t help it. She began to sob again, mostly dry-eyed this time, the complex whirl of emotions welling up in her again until it felt as if she couldn’t breathe, as if she had to choke on them or vomit them up. She didn’t even notice that her arms were free until Satsuki was helping her up- one hand still mussing her hair, caressing her scalp. Ryuko leaned against Satsuki, not sure she could stand by herself, her face buried in Satsuki’s collarbone. 

“D-Don’t…” Ryuko shuddered, “Don’t ever do that again.”

“I’m sorry,” Satsuki said, her hand pausing in its repetitive, calming motion. “I was very angry with you.”

Ryuko’s breath caught in her throat. That was an apology. An actual, unreserved apology with only a hint of an excuse or a justification attached to it. And she hadn’t even needed to work herself up to say it. It had come out naturally. And Kiryuin Satsuki never apologized to anyone .

Taking her silence for confusion, Satsuki continued, trying to clarify. 

“I can tolerate your disrespect in private, Matoi, but for the sake of the academy…”

“I- I get it.” Ryuko interrupted, “But that was too much.” She forced herself to straighten up, her muscles aching, her backside a flaming aurora that rippled where the soft fabric of her skirt grazed the reddened flesh. She blinked the tears from her eyes and met Satsuki’s gaze head on. Satsuki returned it, unblinking. “If you do that shit again, I’ll walk. Contract or no contract.”

Satsuki stared her down for a long moment, and Ryuko’s heart flipped over, but she held firm. Finally, Satsuki inclined her head fractionally. 

“Very well.” she said, “A simple system should prevent any further incidents. Red for stop. Yellow for slow. Green for continue.”

“A traffic light?” Ryuko tilted her head, her thoughts too fuzzy to focus properly, “W-wait, have you been reading up on-”

“Yes, I know traffic lights are more blue than green, but still.”

“Shut up. Alright. Okay. Whatever. Just…” Ryuko slowly leaned back into Satsuki’s arms, her whole body leaden and heavy. “I’m gonna need a ride home.”

Satsuki shook her head, blowing out a breath of amused laughter.

“I’ll take you home. Besides, I’m not finished with you yet.”

It wasn’t until they reached Satsuki’s room that Ryuko realized what she meant.

Chapter Text

“Red…” Kiryuin Satsuki began, an utterly shit-eating grin on her face, “...or green?”

Ryuko glared up at her, Satsuki’s silk sheets like sandpaper against her spanked-raw rear. 

Satsuki smiled back down. It was adorable the way that the tough little brat had to look her in the face when they fucked like this. It turned the usual angry, defiant transfer-student into a flushed, embarrassed mess, mewling out cries of pleasure into the heel of her hand, vainly trying to hide the cock-dumb experession on her face. 

That was all to come though. For now, Satsuki’s revived erection pressed firm against Ryuko’s hole once more, and, solely for the sake of safety, she was checking in with her. 

“...green.” Ryuko mumbled from behind her hand. Satsuki snorted out a breath in amusement and reached down to take her by the thighs, holding them higher so she could lever herself forwards with those muscular hips and-

They gasped, voices twinning as she slid inside. She felt Ryuko clench down on her, muscles flexing as she adjusted to the sudden intrusion. Satsuki waited, longer than she normally would. When Ryuko finally snapped up to look her in the eye, she quirked up the corner of her lips and said, in a sickeningly sweet tone-

“Red or green~?”

“Nnngh, green ,” Ryuko said, frustration tinging her voice, “We already fucked once, I’m ready already!”

“I just don’t want to hurt you!” Satsuki lied cheerfully, easing her hips forwards once more until Ryuko made a quiet, involuntary gasp as she found her prostate. Satsuki stopped once more, letting her length flex and pulse inside the brat’s tight hole, which was already deliciously slick and hot with their early coupling. 

“Oh- was that a red~?” she asked, fake concern thick in her voice. 

“Nnnooo,” Ryuko grunted into the heel of her hand, “D-don’t stop…”

“I won’t know unless you tell me~” Satsuki sing-songed. 

“F-Fuck, green! ” came the answering growl.

The moment the word passed her lips, Satsuki thrust forward mercilessly with every taut, well-toned muscle of her hips and buttocks, dragging herself down to the hilt, piledriver style, into the depths of Ryuko's well used little hole. Ryuko made a noise like she'd been stabbed- a short, sharp gasp, that devolved into a whining noise of pleasure that made Satsuki grin. 

She began to pull back, drawing her length firmly from Ryuko's twitching, desperate backside even as it fought to keep her inside. 

“Oh dear, am I hurting you? Is that a red? I’m so sorry, I’ll pull out right n-”

“Stop fucking with me! ” Ryuko wailed, and her own athletic legs encircled Satsuki’s waist and clutched at her tightly, looping around her hips, her heels digging into that plump, pale bottom. Forcefully she grabbed both of Satsuki’s shoulders in an almost painfully hard grasp and used all four of her limbs to drag her closer until that thick, superior, gently curving rod was balls-deep back inside her where it belonged. She let her head fall back for a long moment, making an unrestrained noise of sinful pleasure as she did so. 

Satsuki stared down at her, a flush on her own cheeks with just how erotic and wanton the girl beneath her looked. This was going perfectly . She chuckled. 

That set Ryuko off, her dick-drunk brain finally putting together that she’d been messed with the whole goddamn time. She glared at Satsuki with those grey blue eyes, her furious image somewhat undermined by the flush spread across her cheeks and neck, the squeezing of her thighs around Satsuki’s waist, and the flexing tug of her backside around the length inside of her. 

“Damn it, Kiryuin,” she swore, “ Don’t fucking pull out, Don’t fucking jerk me around, Don’t keep asking me red or green-”

“Don’t, don’t, don’t,” Satsuki drawled in a bored tone of voice, “You’re so negative, Matoi. How about you tell me something you do want me to do instead?”

Ryuko glared at her, her red bangs and her red cheeks glowing like she was going to burst into flames, but then she looked away and-

"I want you to…” she trailed off, embarrassment winning out over lust for the moment. 

“What?” Satsuki went in for the kill, sure that the bratty Matoi would break under this avalanche of pressure, “Leave you alone? Stop bullying you? Take you out for dinner? ”

She had other taunts planned, but they flew from her head when the words 'take you out for dinner' left her lips with a little more sincerity than she would have liked. Ryuko too, seemed to notice and went stiff, staring up at her, flushed and sweating behind her hand. For a moment, neither of them moved. Neither of them breathed. 

Satsuki simply stayed silent and raised her eyebrow. That was her go-to mistake cover, and it usually worked.

It was Ryuko, the always impatient Ryuko, who snapped first. She shook her head, growled in frustration as if psyching herself up and then finally admitted, her voice loud enough to echo in the spacious bedroom-

"I want you to FUCK me, Sats, and I don’t want you to stop!”

Satsuki wanted to say 'good girl' or 'was that so hard?' Or any other number of teasing things, but her jaw was still shut and her tongue was still tied, and besides, the sheer eroticism of Matoi Ryuko begging her to be fucked until they left an impression in the mattress was too much to handle. 

So instead she took Ryuko harshly by the hips and drew away, only to plunge back in a moment later, sawing her hips back and forth with demented ferocity, using that tight, obedient, already cum-slick hole as if she hated it. They collapsed onto each other, limbs tangling together. Satsuki’s hands gripped the bedsheets and tried desperately to keep her body upright while Ryuko groped at Satsuki’s chest, her shoulders, nails scratching long, crimson marks down her back while she swore and groaned and gasped-  “F-fucking finally -” 

Satsuki silenced her with a bite to her tanned shoulder that made her squeal in pain, but also made her clench down on Satsuki’s thrusting cock like she was already cumming. Satsuki levered herself up into an imposing position above the red-headed girl, flicking her head back dramatically to sweep her sweaty hair out of her face.

“You like being bitten, Matoi? Maybe I should leave one where everyone can see it- would that be better than a uniform?” It was impossible for Ryuko’s face to get any redder, but that didn’t stop her from flinching. Still, she treated the threat like everything else in her life- a challenge.

“B-Big talk for a girl whose dick twitches every time I dig my nails into her back!” Ryuko shot back, demonstrating with another twinned set of scratches that made Satsuki have to actually bite down on her lip to avoid making a noise she swore she was never going to make on Matoi Ryuko’s terms ever in the bedroom. 

“At least mine twitches when it’s inside of something, transfer-student,” she mocked, her temper rising despite the intimate motion of their bodies, Ryuko using her taloned grip on Satsuki’s shoulders to actually fuck her hips up into every downward stroke, slapping their bodies together in a sweaty, furious mating press. “Yours just- nngh bounces around like a decoration-”

“Oh- mmmph- were you inside me?” Ryuko asked in badly feigned surprise between her gasping breaths, “I didn’t- ha- didn’t notice!”

“Oh well then you surely won’t mind if I pull out, will you?” said the mature student council president of Honnouji Academy, like a bitchy middle school student. Notably though, she made no move to do so- she wasn’t sure if she could stop driving her hips into Matoi Ryuko’s accommodating little hole, dragging mewling noises out of her with each motion. She felt a tightness in her core, and tingling rising up each time her heavy orbs slapped against Ryuko’s sore and flaming backside that told her that; a) she did not want to pull out, and b) in less than a minute it was going to become entirely academic. 

“You pull out and I’m go-goahhnna fucking kill you!” Ryuko squawked, clearly approaching some kind of edge herself, her body trembling with exertion. 

“Because despite all your talk-” Satsuki grunted, thrusting back and forth in long, hard strokes designed solely to bring them both over the edge as fast as possible, “-You’re just a dumb, cum-hungry hole who needs a fat- c-cock in her-”

She broke off to moan, unashamedly. God, cumming inside Matoi Ryuko was like heaven every fucking time. She was so close that she could taste it when Ryuko tightened down on her. That was normally a good sign, but this time it wasn’t just her greedy little asshole. This time it was her hips and her thighs and her heels and her arms- gripping not to hold her close and urging her to finish as deep as she could, but pinning her mid-stroke so that she if she wanted to keep thrusting she was going to have to overpower her. 

And those defiant, dick-drunk eyes glared up at her, one eyebrow raised in a mocking imitation of her own stare as Matoi Ryuko gave Satsuki her own shit-eating grin and said, as if being asked to name her favorite color-

“Red.”

Satsuki’s brain…broke. She stared down at Ryuko, wavering between the edge of orgasm and the sheer uncomprehending bafflement at what she had just heard. After a second or two that felt like hours, she managed only a parroted echo of a reply.

“....red?” she asked, hating how stupid she sounded. 

“Red~” Ryuko taunted, then clarified a moment later, as if Satsuki truly were stupid, “It means ‘stop’.”

“I know what it means , Matoi!” Satsuki hissed, her arousal mixing with fury, “What I don’t know is why you’re saying it .”

“Because when I say it, you have to stop.” Ryuko said simply, shrugging as if it were obvious, “And you don’t get to cum in me until I say green again~”

Satsuki gaped at her, mouth falling open in sheer amazement at her pettiness.

“Of all the childish, pathetic power-plays-”

“Oh that’s rich, miss ‘here’s a lewd contract where you’re forced to suck my dick-”

“Nothing about a contract is childish-”

“ Everything about needing a contract is childish.” Ryuko gave Satsuki’s shoulders a push, jerked her head up in a smug little nod. “Hey. Tell me how good it feels to fuck me.”

“What?” Satsuki thought she had at least a tenuous grasp on Matoi Ryuko’s mental state, maybe even her thought process, but this was… baffling . 

“Well you wanted to, right?” Ryuko said as if it were obvious. “You made up all that bullshit about Mako and stress-relief and like, you could have waved your hand and done it to any adoring one-star without going through all the trouble-”

“I wouldn’t lay my hand on a-”

“On what , a student? I’m a student, miss high-and-mighty-morals! But fine, even if you didn’t pick one of those, you could have had Jakuzure practicing her flute skills on you with a click of your fingers-”

“Disgusting! Jakuzure is my friend, not a-”

“Not what ?” Ryuko spat, eyebrows climbing her forehead, her voice teasing but dangerous. “Not a ‘fun toy’? Not a ‘little bitch’? A ‘pig’? A ‘cumdump’? Hell, maybe you’re just worried your stupid donkey-dick would break her!”

“I do not have a-”

“Oh shut up, until you’ve had it in your ass you don’t get a vote. Now stop stalling and tell me how good it feels to finally fuck me.”

Ryuko’s grip slackened, allowing Satsuki to sink back into her with an almost grateful moan. This close to orgasm, she found it hard to think, her thoughts fuzzing with the lust she kept at bay almost all the time. It whispered in the back of her mind like an obscene chorus- slap her, fuck her, choke her, breed her, fill her, take her, use her to feel GOOD-

“It’s good-” she sighed, thrusting back and forth slowly enough to stop herself having a humiliating ejaculation mere seconds after being allowed to move again. After all, what did it matter if she humored her? It was still clear who was in charge. “You feel so good around my cock, Matoi.” 

“Hmph~” Ryuko huffed, but the glint in her eyes and the flush on her cheeks said she was pleased. “Don’t stop- as long as you keep talking nice I’ll let you keep fucking me.”

Satsuki bristled- there was only one person in this relationship that ‘let’ someone do anything , but then her mind backtracked to the word ‘relationship’ and once again it felt like she couldn’t think straight, her hips moving of their own will harder and harder into Ryuko’s backside again until their mingled gasps and the creaking of the bed overpowered her thoughts. 

“F-Fuck,” Satsuki swore, breaking down under the combined pressure of a bratty Ryuko and the urgent pressure in her loins, “Your hole feels so good. You’re such a good girl for me, taking my cock so deep-”

“Yeah~?” Ryuko gasped, triumph in her voice, her arms moving once more to wrap around Satsuki, pulling her tight so that their breasts squished together, nipples grinding, her own decorative cock bumping against Satsuki’s abs, “Gonna cum in your good girl?”

Satsuki hissed, her orgasm rising in her belly. Weirdly, as if from a long way off, she felt something shift beneath her, dimly aware that she had ceded some kind of power from her dominion of Matoi Ryuko, but she could only think of one thing now. 

“Yes, god, I’m gonna cum in you,” she moaned, biting hotly at Ryuko’s neck, hearing her ragged gasps in her ear, “I’m going to fill my good little whore so full-”

Ryuko’s nails dug into Satsuki’s back, her legs locking around her waist; dragging her to the hilt and holding her there. Ryuko’s mouth was wet and hot against her ear, tongue lapping against her lobe as she mewled- 

“Green.”

Satsuki saw stars- reaching a new peak of ecstasy the likes of which she had never known existed. Her first real orgasm- in Matoi Ryuko’s obedient mouth, had been a ten out of ten. Then, when she had taken her over the desk and claimed her insides for her own, her climax had been a twenty out of ten. 

But this?

This might as well have been a hundred. 

Her edged and frustrated cock spurted violently into Ryuko’s depths, filling her to the brim while Satsuki thrust and ground against her ass like an animal- like the humping dog Ryuko had accused her of being once before. Each jet of boiling hot jizz made Ryuko whimper and cry out, her body shuddering, and dimly Satsuki felt her stomach become damp with her partner’s own release. She didn’t care right now though-- there was only the climax thrumming through her like lightning, and the need to empty her balls into Matoi Ryuko’s defiant little hole. 

“M-Matoi~” she groaned, her hands digging hard into Ryuko’s hips until they turned pale. 

“S-Sats-” Ryuko gasped in a choked, pathetic voice, arching her back, pliant and limp now that they had reached their peak, leaving her body to be obediently used to milk out the last of Kiryuin Satsuki’s animalistic urges. 

Eventually even this had to end. Ryuko’s mewling trailed off into breathy pants. Satsuki’s thrusts slowed, then stopped. There was silence then, save for the mingled sound of their breathing. 

Satsuki held her eyes tightly shut, her teeth pinning her lip in place. She could feel herself throbbing, feel the warmth where they were connected. Could feel Matoi’s heart hammering against her own. For a long moment, she wondered how long she could stay like this, and not have to go back to how they were the moment their lovemaking ended. 

When she finally did stir, Ryuko groaned a tired sounding complaint and tightened the grip of her ankles at the small of Satsuki’s back, holding her in place.

“W-Wait…” she sighed, “Just…let’s just stay like this for a minute.”

Satsuki froze, her breath tight in her chest. Dangerous , her doubts whispered, that’s too dangerous…

Out loud, she simply murmured, “...okay.” 

Time passed. Their breathing settled. No longer could she feel Ryuko’s pulse against her own. Slowly, her softening length slid free as she pulled out. They disentangled themselves in silence, Ryuko uncharacteristically quiet as she swept her hands through her hair, fixing its disarray. Satsuki saw no need to be the first one to talk as they skirted around each other, cleaning up as if it were something they did every day. 

“Thanks,” said Ryuko, as Satsuki handed her a wipe. 

“You’re welcome,” she replied. 

That was all they said. All they dared say. Neither of them spoke again as they clambered back into bed. 

Satsuki offered Ryuko her share of blanket, arm extended. Ryuko instead took her arm and the blanket and pulled both around her, leaving them nestled together, skin to skin. Satsuki wanted to shake her, wanted to scream and ask her if she was fucking with her, or if after a long day and a good fuck, Ryuko simply didn’t care anymore. Most of all she wanted, needed to know-

Do you hate me or not?

Ryuko’s quiet, satisfied breathing answered none of her questions. Satsuki grit her teeth and forced her eyes closed, but the weight and warmth of the girl next to her made sleep a long time coming. 

Chapter Text

It took Satsuki a long time to fall asleep, but it never took her long to wake up. This time, when she did, Ryuko was still asleep- a warm, reassuring weight against her side, her back rising and falling in time with her breathing. 

Satsuki tried to move, and had to stifle a hiss as a sudden pain shot through her arm- still trapped beneath Ryuko’s neck and shoulder, and adjusted her body to relieve a little of the weight. Ryuko mumbled something inaudible and nuzzled against the limb, shifting slightly in her slumber. Her motions brought their hips together and Satsuki had to purse her lips to smother another, entirely different noise as her morning wood brushed against Ryuko’s backside. Satsuki lay there, nestled against her… the mind rebelled at the word ‘lover’, and any of the baser, more sexual terms did not fit when the subject in question was snoring gently while they cuddled, so she settled on ‘partner’. When her inconvenient erection throbbed once more as Ryuko ground back against her in her sleep, she was struck by a small, sadistic idea.

After a long minute of gathering her courage, she shifted her hand from Ryuko’s hip, creeping inch by inch around the bare skin until- her fingers bumped something hot, smooth, and hard, confirming her guess. Ryuko’s own morning erection was as stiff and as needy as her own, jutting out proudly from her hips beneath the blankets. A small, mischievous smile crossed Kiryuin Satsuki’s face. It was time for some payback.

Ryuko first stirred at a warm, slick sensation against her neck. She mumbled a sleepy noise that was halfway between a complaint and a sigh when the sensation struck her again, harder. Then Satsuki grazed her teeth against the hollow of her throat and she awoke with a start.

“S-Sats- what ar-ahh-ah-” her question died on her lips as she suddenly became aware that Satsuki’s hand was wrapped firmly around her morning wood and was sliding up and down slowly, stroking her hard cock with a teasing touch that made it quiver and twitch against her palm. Meanwhile, Satsuki’s mouth was on her neck- licking, kissing, biting gently against the sensitive skin. Very soon it was impossible to think, let alone fight back. 

“Mmm…” murmured Satsuki against Ryuko’s pulse, grinning and being glad that Ryuko couldn’t see her face. She used her other arm to wrap around Ryuko’s neck and shoulders firmly, pinning her in place with her back tight to Satsuki’s bare breasts. “Hold still.” she demanded. Ryuko was right , she decided in her head, everyone is less of a bitch when they wake up with something around their cock.  

Ryuko made a gasping, urgent noise as Satsuki began to stroke her faster, her long and elegant fingers wrapping Ryuko’s cock in a soft, tight embrace that jerked up and down in long, quick strokes. Soon she was reduced to groaning Satsuki’s name, one of her hands at Satsuki’s arm around her neck, the other gripping Satsuki’s pumping wrist in a tight grip, as if she were trying to stop her- but instead was simply holding on for dear life and making little pathetic noises of pleasure.

"S-Satsuki-" her voice wavered. Satsuki thought suddenly that Ryuko wasn't sensitive per se, but that she truly was unused to attention being focused on her cock. Any time she had done so previously she had found it almost too easy to drive Matoi Ryuko to the edge in a scarce handful of minutes. Not that this was a negative for Kiryuin Satsuki- on the contrary, Matoi Ryuko’s premature penis was a source of endless amusement, humiliation, and pleasure to her. So she turned her head and gently bit the pale lobe of Ryuko’s ear and made her gasp. 

“Already~?” she sing-songed, and watched as the blood-red blush crept up Ryuko’s neck and cheeks. 

"Please-" Ryuko gasped, brain unsure what she was begging for even as her body replied, thrusting her hips back, grinding her backside against Satsuki's own prodigious morning erection. Satsuki bit her lip to avoid sounding too desperate. That was a tempting option, but fetching lubricant would be a momentary interruption she did not want to deal with, and in any case the morning mood was so fragile that she was afraid that if she stepped away, even for a moment, their truce would shatter like glass.

So instead she tightened her grip around the girl’s shaft and pumped her wrist harder, faster- til Matoi was biting down on her lip vainly to stifle her pathetic noises of arousal. This was how things were supposed to be, Satsuki thought to herself with a superior, almost smug smile on her face, Matoi Ryuko begging me for whatever I deign to provide, her body and mind contorted in pleasure . 

"Sats, f-fuck, just like that-" The actual Ryuko’s voice broke in on her thoughts, the wavering in her tone letting her know through experience that she was at the end of her metaphysical rope. 

"Close for me, Matoi?" she asked, for formality. The question was not a sincere one. It was designed solely to humiliate the answerer, and by Ryuko’s flush and shudder of submissive pleasure, it was doing its job. 

"Yes, god yes-"

"Do you have permission to cum?" She whispered into the shell of her victim's ear, grinning as she felt the girl's entire body thrum in response. She slowed her stroking pace, edging the red-haired girl with a slow, circular motion of her wrist around the sensitive glans. Ryuko made a strangled, pathetic noise. 

"No, I can't- I don't, please let me-"

"Ask nicely. You know what I want to hear."

Ryuko was overjoyed that she was facing away from the dominant woman behind her, because that let her cram her flushed and humiliated face half into Satsuki's alabaster, eight-hundred thread count sheets and mewl like a bitch in heat, humiliation turning her voice thready and weak. 

" Please - a-ah, please let me cum like a good girl!"

There we go, Satsuki thought smugly, dragging her hand up and down faster and faster, I win.

"Do it, loser." Satsuki hissed, dragging her mouth down Ryuko's ear towards her neck. Just as she heard a tell-tale noise in Matoi's throat, she opened wide and bit down hard on the side of her neck, vampire-like, clinging on tight over her hammering pulse.

Ryuko made a strangled, almost sobbing wail, and went off in Satsuki's stroking hand like a firework, her abject release almost spilling through her slender digits as she moved to cup a second hand around the girl's throbbing glans, jerking her through her climax into her cupped palm.

“There you go-” Satsuki mocked, her tone a conciliating whisper, “Let it out. You can’t help being so quick, so pathetically premature. That’s a good girl. You’ll just come for a few strokes of your inferior thing as long as someone bullies you, won’t you? Good girl~ ”

Despite her continual bombardment of humiliation, Satsuki was in awe. It was intensely pleasurable to watch Matoi Ryuko climax under her hand- the base, freeing way that she came, body stiffening, hips bucking animalistically, mouth babbling moans and pleas and nonsense, so consumed with pleasure that her brain simply shut off. Satsuki wasn’t sure she had ever come so hard, or if she would handle it any better than the transfer student would. Also she wasn’t sure that if she didn’t stop soon, her hand wasn’t going to overflow. 

Finally, Ryuko’s bucking, shuddering motions drew to a halt, leaving her sweaty, pliant, and panting against Satsuki’s chest. Satsuki squeezed the base of Ryuko’s member and dragged her fist upward, finishing her with two, humiliating strokes that felt like she was being milked into Satsuki’s waiting, sticky palm, then released her. Ryuko shivered, reached up and tweaked her red bang, slick with sweat, from her face. It took her three attempts, her hands were shaking so badly. 

They lay there for perhaps a minute, in silence besides the slow breaths and quick pants of their mingled bodies before Ryuko, with evident reluctance, gnawed on her lip and said-

“...t-thank you.” 

Satsuki grinned unseen. Thanking her without being prompted? What a good girl. Still, it would do nothing to acknowledge it so easily. So instead of praising her, she pushed harder.

“If you want to actually thank me,” she huffed, lifting her soaking, sticky hand still thoroughly plastered in Ryuko’s release, “Then you can clean up your mess.”

Ryuko froze, her face still hidden from Satsuki’s eyes, but she could see the flush traveling down her neck- and over the deep, already bruising bite mark over her carotid. Her patience snapped.

"You're fucking jo-"

"I don't joke, Matoi.” Satsuki interrupted, cutting off her protest, voice iron-hard. “Be a good dog and lap up the mess you made."

Ryuko flinched visibly at the words ‘good dog’, but still hesitated, her face inching towards Satsuki’s proffered hand, and the sticky mess within. She moved slowly-- too slowly for Satsuki, who rolled her eyes and said, "Come on now, don't waste my time. If you can swallow mine day after day, yours should be no different. Although I'm sure mine tastes better."

Am I really going to do this? Ryuko thought to herself. Her skin felt hot and tight, and she couldn’t catch her breath. Her brain felt fuzzy with the aftershocks of her orgasm, and the submissive desire deep in her stomach that told her that she wanted nothing more than to be a good dog . Her head craned forwards, and her mouth fell open, tongue hesitantly passing her teeth and she realized that, yes, I am. Then she was nuzzling against Satsuki’s palm, her hot pink tongue lapping up her own release, wrinkling her nose at the salty taste and slimy texture, but feeling a warm inner glow despite that. 

The feeling blossomed brighter as Satsuki huffed out a breath of laughter and said, her smile visible in every word- “What a good dog you are, Matoi.” Fuck, she swore, not another degrading thing I’m into…

To disguise the unpleasantly warm feeling in her stomach once Satsuki’s hand was clean and slick only with her saliva, she blew out a breath and grumbled-

"It doesn't, by the way."

"Doesn't what?"

"Taste any better."

"Oh shut up."

Ryuko finally shifted, rolling over to give Satsuki an annoyed look. However, the motion propped her up on one arm but left the other arm swinging free- where her hand promptly bumped against something long, hot, and extremely hard. She flinched in surprise, then recovered, wrapping her hand clumsily around Kiryuin Satsuki’s shaft and giving it a tentative stroke from the thick base to the tapering glans as if she had been intending to reach for it all along. Satsuki breathed out a slow sigh, laying back and making no motion to either encourage nor discourage Ryuko from her exploration. 

For a moment or two Ryuko merely stroked her, her grasp gentle and appreciative. She didn’t often get to take her time with Satsuki’s member, and seeing it up close without pressure gave her a greater, somewhat humiliating sense of appreciation for just how amazing it was. Of course Queen Perfect Kiryuin Satsuki had a perfect cock-- thick at the base, jutting out from her hips in a gentle curve of soft, smooth pale skin leading up, all the way up, to a gently flaring glans that she knew from experience felt just right sinking into her…

She swallowed roughly, shocked by the wave of arousal hitting her, rising up from her lower belly as she stroked and admired that Kiryuin cock rising up before her. It was almost elegant, really, but then the fierce heat; the throbbing, almost animalistic vein that rose up the underside; and of course the sheer size of it, turned a potentially beautiful cock into something more primal and dangerous, something frankly imposing . Did she really need to be that big ? Where did she hide it in her outfits anyway? She realized that her mouth was slack and that she’d been…well, fawning over Satsuki’s cock for a little too long, and her bedside partner now had a small, distinctly smug smile on her face. 

Ryuko grunted and let her hand slide down to the base of the impressive member and give the base an almost affectionate little squeeze. 

“Well, what about this?” she asked, trying to sound bored instead of eager.

"What about it?" Satsuki said, raising an eyebrow. Ryuko grit her teeth and gave her a look that said ' Don't start .'

"As you keep telling me, it's my job to 'take care of it',” Ryuko drawled, emphasizing the euphemistic words until they were dripping with sarcasm, “So how do you want me to 'take care of it'?”

“I’m sure you’ll think of something~” Satsuki said smugly, folding her hands behind her head and relaxing. Ryuko stared at her for a long moment, then when no further words were forthcoming, rolled her eyes and flung her leg over Satsuki’s hips in a single smooth motion, straddling her. Satsuki raised an eyebrow as Ryuko reached back and stroked her, then looked down at Satsuki and grumbled, “I’m gonna need some lube.”

Satsuki deigned to reach out and grab some that she’d clearly stowed beside her bedside lamp for just such an emergency, and tossed it at Ryuko slightly too hard. She still caught it however, and soon Satsuki was shivering as her length was dowsed in slick, ice cool liquid that Ryuko dutifully massaged into her throbbing, eager shaft until it was slippery beneath her trembling fingers. She swallowed roughly, composing herself for what she was about to do when she made a mistake. 

She looked down at Satsuki. 

Suddenly she was all too aware that this position left absolutely nothing to the imagination, and unlike being bent over a desk or lying on her back with her face averted, Satsuki could not only see her whole, gloriously naked body, but watch her debase herself by actually performing the work herself- putting on yet another show for a smug, humiliating audience. She froze, her teeth gnawing at her lip, caught between the warring desire and shame in the pit of her stomach.

Finally Satsuki lost her patience. She leaned up just far enough to give one of Ryuko’s tanned buttocks a hearty smack with her palm, dragging a yelp from her lips, and when she was glared at simply raised an eyebrow and met her gaze implacably. 

“If you’re going to get me off then get started,” Satsuki drawled, as if she were intolerably bored. Ryuko glared down at her harder, knowing that she was trying to rile her up and still falling for it anyway because she was just that fucking annoying. 

She lifted herself awkwardly onto the balls of her feet, hand reaching between her legs to wrap around Satsuki’s imposing length. Now that it was slick with lube, it was even harder to manage, and she couldn’t see what she was doing. Any hope that she would come off like a suave, seductive power-bottom faded as she fumbled, bumping the slick glans of Satsuki’s cock against her inner thighs and buttocks, grinding it against her hole only for it to slip away at the last moment. 

It was only when Satsuki made a grunt of annoyance and deigned to help hold Ryuko’s legs and hips steady that she managed to get the angle just right and-

Their voices blended together as Ryuko slid noticeably downwards- Satsuki hissing a groan through her teeth while Ryuko made a noise like she’d been stabbed. Which, if you’d asked her, she had. Even with plenty of lube, the force of her hips and gravity combined had introduced a little more of Satsuki than she had been ready for, and now she was stuck. She made a mewling, desperate sound- half pain, half pleasure, as she tried to shift her position. She couldn’t, her feet sinking into Satsuki’s soft mattress, leaving her no choice but to let herself slowly fall, impaling herself on that fat, curving, seemingly infinite length. 

By the time she felt her bottom touch those muscular hips, there was so much of Satsuki inside her that she felt as if she couldn’t breathe. Couldn’t speak. Couldn’t move except to gently wiggle her hips, trying to force herself to relax and adjust to the swollen intrusion. Her face or her noises must have been comical, because Satsuki looked up at her smugly and asked- 

“Are you alright up there?” 

“Yes, fuck you very much. I just- a-ah, you have t-too much dick.” Ryuko shot back shakily. 

“Do you need more lube? Don’t rush.” 

This was not smug, and Ryuko’s cheeks were flushed as she accepted the little bottle again, squirting it liberally onto a hand that she slid between their bodies, where they were joined. That had been said with real worry, real concern for her pain, for her comfort in what they were doing, and she was really struggling not to think about exactly what that might mean.

She distracted herself the only way she could- by slowly lifting her hips until the sense of pressure and breathlessness retreated, and then slowly grinding herself back down once more, til Satsuki’s cock was so deep inside her it felt like it was jabbing her in the lungs and coring her out entirely. While she rocked her hips slowly up and down, she began to gasp a litany of complaints every time she had enough breath to do so. 

“Why- d-do you even have su-ahh-ch a stupidly b-big dick anyway?” she grunted between downward thrusts, her skin warming from the exertion and from Satsuki’s gaze on her bare body. In response Satsuki simply slid her palms up Ryuko’s toned stomach and over the plane of her ribs, taking her breasts in her hands and cupping them, squeezing them tenderly. The red-headed girl bit down on a pleased little sound, unused to the attention there. 

“It’s- it’s so you . So f-fuuuaaahh- cking over the top -” The smacking slap of their mingling hips made her flush as she spoke, her motions becoming more confident and powerful as she found a comfortable rhythm, the ache of Satsuki’s thickness fading as she relaxed into it. “And- and then you make me do a-ahll the fucking work-” 

“Are you kidding me? I usually bend you over my desk and do all the work , thank you very much.”

“S-Shut up- this position i-is way more emba-ahhh~ embarrassing!”

“And like everything embarrassing I make you do, you’re getting off on it.”

“A-Am not! I’m not even h-hard!”

Satsuki’s hands gave her breasts another generous squeeze, palming her nipples, running her thumbs over them and pinching lightly- just hard enough to force a gasp from her throat.

“Because you already spurted into my hand -” she pinched harder, making Ryuko mewl, “-like a premature bitch . But now look at you.” She did so, looking Ryuko up and down with a gaze that made her cheeks burn with unremitting shame. She had sweat sheening on her body, her hands on Satsuki’s hips and stomach, white knuckled. She was bouncing her hips like a slut, her curves shaking and jiggling appealingly all for Satsuki to see. 

“S-Shut your m-moowwhhhh~” She tried to argue, but Satsuki cruelly flexed her hips, thrusting up just as she slid downwards, and she saw stars as that fat length bruised her prostate, drawing another strangled moan from her lips. 

“Oh be quiet,” Satsuki said, rolling her eyes, “You look like such a good girl riding my cock with your flaccid little decoration bouncing around. That's how you should look all the time.”

Almost against her will, Ryuko glanced down, and immediately wished she could simply die of embarrassment. She wasn’t lying when she said she wasn’t hard, but that relieved none of the humiliation she felt at watching her limp member bounce, sway, and flop uselessly as Satsuki’s bigger, thicker, harder, better dick pierced into her from below, highlighting the gulf between their respective positions. 

All that said, it didn’t stop her from rocking her hips back and forth, grinding down against Satsuki’s obnoxiously pointy hip-bones as her dick bottomed out inside her. After one particularly deep wave of pleasure, she let herself fall, her thigh muscles burning, her hands thumping into the pillow either side of Satsuki’s fanned out hair and annoyingly smug face. Her motions moved from bouncing to sliding, rolling her hips up and down so that Satsuki’s cock would hit up against that sweet place inside of her, the pleasure starting to make it difficult to think about how embarrassing this was, or how much she hated her, or anything else-

“Yes, that’s more like it,” Satsuki said, her hands sliding around Ryuko’s thighs to grope and squeeze her hips, urging her on, grinding her down onto that thick length with each stroke until gasps and mewls were being forced out from her lips. Ryuko grunted in anger but couldn’t muster the words to protest. Soon they were truly mingled, with no sense of where one of them began and the other ended. 

“D-do I have permission this time?” Ryuko asked teasingly. She’d chosen her moment well. Satsuki was getting close, and it was clear from her glazed eyes and harsh breathing that all she could think of was how incredibly good Ryuko felt around her cock. It took her an eternity to blink and answer.

“Permission?” Her tone was confused, strained.

Ryuko leaned somehow closer, until their breath mingled and they were forehead to sweaty forehead. She licked her upper lip deliberately, and with a flash of insight, Satsuki knew what she wanted. If she hadn’t already been sweating, she’d have broken out in a cold one. 

“Don’t play dumb. Do I have permission?”

Satsuki’s mind flashed back to their previous kiss, the sensation of Ryuko’s mouth on hers, hot, hungry, and wild. If Ryuko kissed her right now she was going to fucking lose it . 

“Not a chance, I-” she began, her mouth opening. 

This had evidently been all Ryuko had been waiting for. Ryuko’s lips lunged forwards, pressing against her own, while her tongue impudently slid into that vulnerable opening, toying with Satsuki’s own. Shock and pleasure blazed through her from the tip of her tongue to the soles of her feet. Her hands tightened on Ryuko’s hips as she tried desperately not to do what she knew she was going to do. 

It was too late. Satsuki’s iron willpower melted under the sheer heat of Ryuko’s kiss. She wound her tongue against the muscle of the girl on top of her, kissing her back as she felt Ryuko chuckle breathlessly against her lips. Her hips juddered upwards, thrusting spasmodically as her control snapped. Her awareness narrowed solely to Ryuko’s tongue on hers, and Ryuko’s snug little hole around her cock. 

She made a frankly embarrassing noise into Ryuko’s mouth, and then she was coming, thrusting up once, twice, three times into that tight little ass as her climax surged through her. She ground and fucked it out of her animalistically, hips rising up off the bed to plunge her length back and forth, sawing it into Ryuko’s rhythmically squeezing little hole. She felt it when Ryuko finished for the second time, somewhere in the midst of her own orgasm- a mewling cry against her lips, a warm wetness against their mingled bodies, and took a small reprieve in her dignity that she hadn’t been the only one to utterly lose it. But then, she expected better of herself. 

Ryuko broke the kiss to breathe, grinning madly against Satsuki’s shoulder as she felt the aftershocks of their climaxes shudder through them. It had worked! She was right! The great and almighty Kiryuin Satsuki got off on kissing more than anything else. The one act she couldn’t tell herself was just mechanical pleasure, just ‘stress-relief’. Her celebration was cut short however, when Satsuki rose up from the bed, flinging her to the side with surprising force for someone she’d just ridden into exhaustion. She hit the soft mattress and pillows with a -thump-, gazing up stunned.

Kiryuin Satsuki was standing there, glaring absolute daggers at her, like a sweaty, messy haired avenging angel of death. Her defiance was somewhat undercut by the half-hard erection bouncing at her hips, but still, Ryuko thought, she looked properly angry.

“What, no cuddling this time?” Ryuko said, because it was in her nature to be a fucking brat whenever she was scared.

“Shut. Up.” Satsuki said through gritted teeth, “I gave you a direct order-”

“No you didn’t!” said Ryuko, playing the squabbling little sister, “You just said I didn’t have permission!”

“That’s the same damn thi- ”

“Well you kissed me back!”

“That- I did not agree to you sticking your tongue in my mouth and-” Satsuki’s face was blanched with anger, her fists clenched. Ryuko wasn’t sure what exactly was going to happen when she snapped, but she was pretty sure it would either be a good fight or a truly excellent round two.

“Kiryuin, you just fucked my actual asshole and finished inside me . You don't get to complain about a kiss ten seconds after using me as a frigging cumdump. ”

Satsuki’s cheeks began to flush pink at that, off-balance and flustered by just how much she enjoyed that description despite her anger. “There is a difference, Matoi!” she managed to squawk. 

“What, because you’re saving yourself for marriage?”

“Oh fuck you, Matoi.”

“You just did, Kiryuiin.”

Satsuki threw her arms up in despair. “Okay, you know what? I’m not doing this. It’s like arguing with a stupid fucking mutt.” She skewered Ryuko with an accusing finger. “ I am taking a shower. You are staying there. And that is a direct order.” Each sentence was emphasized by a jab of the finger as Ryuko rolled her eyes.

As Satsuki stomped through the bathroom door, Ryuko slumped back from her half-sitting position and sighed. The sound of the shower started, half-muffled. Ryuko felt a twinge and then called after her. “Fine, be that way- but I’m gonna leak on your expensive sheets!”

A moment later she caught a glimpse of Satsuki’s furious face and a blur of motion. Her reflexes saved her from the rolled towel that Satsuki whipped full force at her face, letting it smack ineffectually against the bedframe. 

“Sit on that and shut up! ” The bathroom door slammed shut so hard it rattled on its hinges.

“...yes ma’am~” Ryuko sighed to herself.

Clearly, the mood was over.
