Clicking her teeth while readying to steam the vegetables, Makoto felt them with her tongue to check if her suspicions were on point. She’d been grinding her teeth, she must’ve. Which was another thing to fret over resulting in her grinding her teeth more.

The principal had tasked her with finding the elusive group known as the Phantom Thieves. This unusual, and unreasonable, request was stacked atop her tower of responsibilities as student president, her afterschool aikido lessons, and keeping her grades from slipping. Each task she was given went something like this: work hard, come up short, get lectured, go back to working hard.

Such was the endless cycle that was her life, or perhaps it was more of a spiral. The girl certainly felt she was spiraling with every passing day. She was failing at every turn and Ann Takamaki had only reinforced that notion. She’d been tugging at her hair, grinding her teeth, and chewing on her fingernails. It was only getting worse, she needed to do at least one thing right in her life. Hence, she was going to make her sister Sae’s favorite dinner. Freshly steamed vegetables, seared salmon, and a healthy side dish of pickled radish. Good for the immune system, the mind, and energy.

She just needed to do one thing right.

Dinner was getting cold.

Makoto waited patiently at the door like a trained puppy. Her sister should’ve been home an hour ago, but it must’ve been another late night at work. She’d hoped Sae would’ve bothered to call, but it must’ve slipped her mind again. It wasn’t her fault; her sister had a very important job as a public prosecutor. The young girl’s needs paled in comparison to what her sister was expected to do.

But…

A certain other need had been building since coming home. No, earlier, since Ann had chewed her out in front of those two other boys. While it had been humiliating and stressful, it’d also had a different effect. The way her long flowing pigtails shook with rage; made Makoto’s mouth water. Something about strong women made Makoto weak in the knees. And she desperately needed to take care of it.

Glancing at the door a final time, as if expecting Sae to suddenly barge in, the girl took a chance and rushed across the sitting room and towards the bathroom. Sliding the door shut behind her, she clicked the lock and shuffled in front of the toilet. Hoisting the hem of her skirt, the teenager quickly tugged down her stockings.

She let out a long sigh as her hard cock sprang from its confines. It’d been straining against the insides of her tights all day. They’d been specially ordered to hide Makoto’s difference from the other girls in class. While they did allow for a pocket in the front, to best hide her package, they also were more constricting than regular stockings and she hated putting them on.

But it couldn’t be helped. Being surrounded by peers like Ann Takamaki, Haru Okumura, and that new Yoshizawa girl had her dick staining the front of her tights with precum. It was getting so bad even Kawakami was looking good to her, she desperately needed to get off, but all her responsibilities were taking so much of her time. Certainly, no time for a girlfriend, leaving her feeling even more pent up and alone.

Before the Phantom Thieves, she would reward herself after a night of studying by jacking off at least three times before falling asleep. Now, it’d been nearly a month since she’d last had a moment to herself. Her balls ached and her cock was brimming with seed. It would just take a few minutes, maybe just one, and she’d be good for another month.

Wrapping her hand around her cock, Makoto let out a sweet moan as she ran her thumb over the head. She needed this, badly, she just needed to be quick about it. Scrunching her eyes tight, she began pumping her fist up and down her length. Her foreskin pulled back and forth as she fucked her hand fast and hard. She just needed a fantasy, some image in her head she could focus on.

Ann? Yes. Ann called her out again. Only this time, she’d snap back. This time, she’d bend the girl over a railing and flip up her skirt. She’d rip a hole in her stockings, release her throbbing cock, and thrust it into the girl’s waiting hole. Ann wasn’t the type to wear panties, the slut, she’d be ready for her. Dripping. Ann would be her first, the first tight and sweet hole she’d ever get to-

Bzzz

The door.

Makoto jumped but kept her cock in her hand. Just a few seconds more, she was so damn close.

Bzzz.

Just…

Bzzz

Bzzz

Bzzz

Makoto swallowed a groan, tucking her cock back inside her stockings and pulling down her skirt. She ran to the mirror, checking her appearance and smoothing down any wrinkles in her clothes. Her cock ached inside its’ confinement, and it took everything in her not to strip down and fuck her hand silly. But she had responsibilities.

Quickly washing her hands, she rushed to the door. She could take care of herself another time. Tonight was too important. She needed to make certain dinner went off without a hitch. The food was probably still warm, the apartment was spotless, and she needed to be as presentable as she could be.

She just needed to do one thing right.

“Isn’t it about time you grew up and acknowledged our situation!?”

Makoto’s chopsticks trembled in her thin fingers.

“Right now, you’re useless to me.”

Makoto’s parched throat swallowed a sob.

“All you do is eat away at my life.”

Makoto’s gentle heart broke.

Sae Niijima let out a long breath, her pale face tinted with a bit of pink, an obvious indicator she’d been bottling everything up for quite some time. Swiping some of her long ashen hair from her face, the woman pursed her lips, and Makoto hoped an apology was about to follow.

Instead, her big sister said, “And your condition doesn’t make things easy either.”

“My condition?” Makoto squeaked.

“Don’t act like you don’t know what I’m talking about,” Sae snorted, “All the stockings you go through? The reason we can’t go to a bathhouse? All the secrecy around your physicals? Dad might’ve accepted you, but you’re just…some freak. Why do you think Mom left after having you?”

“Wh-what?” Makoto whimpered, tears welling in the corners of her eyes. Was that true? Nobody talked about her mother, was that the real reason she left?

“I’ll be eating dinner out from tomorrow on.” Sae huffed, collecting her plate, the meal scarcely touched. “Oh, and the fish?” Makoto’s perked up, “It was cold.” Sae stood up, stalking off towards the kitchen.

Makoto stared at her plate; she hadn’t eaten much either. Instinctively, she fell backward into deep breathing, trying to soothe her frayed nerves. It was only a couple of breaths in when she caught herself tugging at her hair. She wanted to break down, fall forward, and just cry. But there wasn’t time for that. She needed to clean the kitchen, study for tomorrow, and get herself ready for bed. There was too much to do and not enough time.

Makoto looked up, watching her older sister’s hips swaying as she stalked off. She never noticed how plump her sister’s backside was, never noticed how her breasts were so large she could see them even from behind. Her cock swelled, but the stockings kept it locked in place. Trapped. Suffocated. Something was going to give. Something had to break, or she would.

Makoto stood from her chair, silently, and tucked her hand beneath her skirt. She ripped the front of her stockings open, and her cock sprung out already hard and dripping. It throbbed with need, and tonight she would finally sate her month-long denial. 

Nearly a whole head shorter, Makoto usually felt intimidated standing in the shadow of her sister, but her twitching cock gave her the courage to strike. Kicking the back of Sae’s leg out from under her, she toppled her sister to the ground. The woman caught herself before faceplanting on the ground, the plate smashing against the floor as it flew from her hands.

“What the hell?!” Sae screeched, her hair whipping around as she glared over her shoulder. Her eyes went wide, and Makoto knew she’d gotten a view of her cock tenting her plaid skirt. The woman began to scramble away, but Makoto surged forward and roughly seized her by the hair.

Dragging her backward until her back arched, Makoto’s dick excitedly pulsed seeing her sister’s chest thrust forward, her breasts straining against her black dress shirt. They were so large, plump, and juicy, and the younger sister licked her lips. Makoto dragged Sae toward the living room, the older sister screaming in protest.

“Let me go of me, you little freak!” Sae snarled up at her.

SMACK

Makoto’s hand should’ve stung, but she didn’t feel it, all she felt was how hard her cock had gotten. Panting, eyes wild, the girl sat down on the sofa with her dick pointed straight in the air. Whatever logical and rational thoughts she had were seared away by the ache in her balls and the hurt in her heart. She wasn’t useless. She wasn’t a freak. And she would drive this message into her sister until she saw otherwise. Even if it meant driving herself into her sister’s unwilling holes.

She grinned, seeing Sae’s lip quiver as the older sister held her reddening cheek.

“Is that the first time you’ve been hit like that?” Makoto seethed, letting go of her sister’s hair, “It won’t be the last if you don’t do everything I say.”

Taking advantage of Sae’s stunned silence, Makoto released her hold on her older sister’s hair and grasped either side of Sae’s button-up shirt. With a quick tug, buttons went flying and scattered all over the floor like pebbles.

“Wait…what are you?” Sae began, but Makoto was too far gone.

A lacy bra. Just for her. As much as she’d love to admire it, her cock craved attention. With almost inhuman strength, she tore it open, shredding through the expensive undergarments. Large and creamy breasts popped free, and Makoto quickly began mauling her sister’s tits. They were so soft and supple, except for the nipples. When she ran her fingers over them, they hardened beneath her touch. She needed more.

Makoto was a good girl. She never went looking for porn, but it somehow seemed to find her. One night, while studying anatomy, she stumbled onto a site she shouldn’t have seen. Immediately, she went to click off it, but her eyes locked on a clip repeating over and over. It was a woman, with tits like her sister, pressing them together as a man’s cock thrust between them.

Makoto didn’t get much sleep that night.

“Get away…” Sae said, though there was fear in her voice this time, “…please…”

For a split second, Makoto flashed back to her regular self. This was her sister, begging her to stop. Her eyes fell to her hands, the same ones that struck Sae’s face and yanked on her hair. Was she this much of a monster? To abuse the woman who raised her, fed her, and housed her?

Seemingly sensing Makoto’s weakness, Sae said, “We can forget this ever happened. We can move on. I forgive you.”

Forgive?

“I really want to believe you,” Makoto whimpered, “But I know you, Sis. I know you’ll never let this go and you’ll send me away. You don’t forgive or forget. And… maybe I am a freak and mom left because of me. But the way I see it, it’s already too late. There’s no changing what happened.” She stiffened, “So…I need to make the most of this while I can.”

“Makoto! Please! Wait!”

Ignoring her pleas, Makoto hoisted her sister’s breasts into her lap. They were so heavy, and her dick leaked a dollop of precum in excitement. Inching forward, she rubbed the head of her cock over Sae’s right nipple. A shiver was sent through the girl’s entire body, and her head rolled back as she groaned. She bucked instinctively, her cock head dragging over the soft flesh. It was smooth and warm, like melted butter.

Sae squeaked as Makoto dragged her upwards, forcing her into a kneeling position. The woman was nothing more than something to use her cock on. The girl’s eyes followed the jiggling orbs, flesh so full and enticing she wanted nothing more than to give them little love bites. But that could wait.

“Sis…” Makoto moaned and rammed her cock between Sae’s tits. The older woman squealed as Makoto dove into her cleavage. Her big sister was so warm; it was so much better than her own cold hand she tried making love to earlier that night. Sinking her nails into Sae’s tit-flesh, she mashed them around her cock and let out a mewl of pleasure. Wrapped in a pillowy and warm embrace, she twitched feeling Sae’s heart thundering in her chest.

“No, no, no, no,” Sae whimpered, “…don’t do this.”

It was too late, Makoto mind was drenched in euphoria and her hips began bucking like mad. The little girl moaned in ecstasy as she humped her sister’s chest. Shutting her eyes, she focused on the feelings rocketing through her dick. Precum lubed the way as the head of her cock peeked out and disappeared between her sister’s cleavage. She pressed them together tighter, creating a vice-like grip around her member. She was so close already. Nothing in her miserable life had ever felt so wonderful before.

“Makoto…”

Looking down, she saw her sister’s own brown eyes pleading up at her. Her flawless complexion had pinkened, her once thin lips now open in the middle of a sob, and streaks of tears trailed down her cheeks.

“Don’t do this.”

Makoto roared as she came, blasting her load all over her sister’s perfect face. It felt as if the head of her dick had exploded, her little body battered by the pleasure rocketing through it. A month’s worth of thick and gooey cream shot out of her cock like a shotgun. Painting her sister with hot white cum.

Rope after rope gushed over Sae’s forehead and draped over her nose. It pooled in her eyes and dribbled over her lips. It seeped off her chin before dribbling onto her perfect tits, tits that Makoto was still violently thrusting between as she rode her orgasm to higher heights.

White hot ecstasy burned through her nerves and fried her synapses. Her body took complete control as it sought out the most pleasure it could milk from Sae’s body. It slammed her sister’s magnificent tits up and down her still cumming cock. Though her spurts were weakening, the fresh hot cum coating her sister’s tits was more than enough to keep her humping.

Cum soaked through the remnants of Sae’s shirt and doused Makoto’s stockings. It dribbled onto the rug and stained the couch. But her thrusts were getting weaker, and despite her dick still pulsing no cum was coming out. Her little body shook, her chest rose and fell as she panted, and then she collapsed against the back of the sofa. Eyes rolled into the back of her head.

Sae fell back, barely able to see through the cum coating her pristine features. With shaking fingers, she wiped it from her eyes and blinked away the stinging salty cream. She looked down at her trembling hands, smothered in her sister’s cum. The woman wanted to sob but was too afraid to open her mouth lest more of the incestuous seed slipped inside.

Makoto was asleep, drooling on the sofa, meaning now was her only chance. Her sister was far stronger than she suspected, and unlike Sae, she was still taking her Aikido lessons. The prosecutor had come home exhausted and didn’t have any fight in her after that slap. She had even less fight left in her now.

Quietly standing back up, she felt the heavy cum dripping off her nipples and splattering on the floor. She shuddered, but quickly made her way out of the living room and back toward her bedroom. Her phone was still in her jacket, she just needed to fetch it and get her sister the help she needed. She hadn’t meant to say all those things earlier, and she was genuinely sorry about it, but after that night she wasn’t sure how she felt about her Makoto. But…was turning her in the right thing to do?

Stumbling down the hall, her heavy tits swaying, she was about to turn the corner into her room when she was slammed against the wall. Her mouth opened as she cried, salty cum flooding her mouth. The side of her face smacked into the drywall, smearing the cream back over her eye. Her tits mashed against the wall, making squishing sounds as she writhed. She struggled to push herself off, but a strong arm held her still.

“Where were you going, Sis?”

Sae groaned, feeling something hard press against her plump ass. She was hard again, already? Having been with only a few partners before, Sae had never known them to recover this quickly. Did it have to do with her sister’s youth? Whatever the case, all she could focus on was her little sister grinding her cock between her legs.

“Oooh, this feels good,” Makoto gushed, humping Sae’s crotch as she held her against the wall. “Did I ever tell you I thought you were the prettiest woman in the world? Oh yeah, I did. And then you said I was a pervert and threatened to tell Dad. I was so afraid of upsetting you.”

Sae trembled as Makoto’s warm hand stroked the small of her back.

“Why do you hate me? Is it really because of Mom? If it is, I’m sorry! But I can’t do anything about it! You have no idea what I’ve been going through, and I just want to make you proud! But if I can’t do that…then I’ll become what you think I am!” 

SLAP!

Sae shrieked as pain shot through her ass. She’d been spanked. She, a grown woman, spanked. She wriggled to free herself, but Makoto held her fast.

SLAP!

SLAP!

SLAP!

Tears mixed with the cum as she wept, her fight was over before it even started.

“Are you going to be good for me?” Makoto asked.

Sae nodded.

“I didn’t hear that.”

“Yes!” Sae cried, “I’ll be good. Just don’t hurt me again.”

“Good,” Makoto stroked her sister’s stinging backside, Sae hissing as her sensitive flesh was grazed. “But that’s not enough. You know that, right? I need something else from you.”

“Anything you want!” Sae screamed, “Just don’t hurt me!”

“Anything?” Makoto said, her hot breath blowing against the back of Sae’s neck. “Anything I want…” Her hands cupped Sae’s other ass cheek. “I want…I want to know…did you have sex when you were my age?”

“What?” Sae asked, startled.

“Did you fuck anyone?” Fingernails dug into Sae’s sore cheek. “Answer me honestly!”

“Yes!” Sae squealed, “Yes! I had sex!”

“With how many people?!”

“Three!”

“Three…” Makoto let go, and Sae let out a breath. “I haven’t even had a girlfriend. I’ve never even…even held hands. Or…or kissed someone.”

“Th-theirs still time! You’ll find someone!”

“In juvenile detention, right?” Makoto asked, “No. I don’t want my first time to be behind bars.”

RIIIIIP

Sae jerked, feeling the crotch of her pants torn open. Again, she tried to throw herself off the wall, but Makoto was impossibly strong. She squeaked, feeling fingers pull her panties aside. Something slick and warm rubbed against her pussy, and she fought even harder.

“So, this is what it’s like…” Makoto moaned, rubbing herself over Sae’s mound, “A real vagina…it’s…warm. Soft. Feels good.”

“No!” Sae screamed, “Get off me! No!”

“You don’t want to be my first, Sis?” Makoto asked.

“No!” she shrieked.

“Maybe…maybe we can be each other’s firsts?”

Sae’s whole body froze when that same hard thing prodded between her ass cheeks.

“You ever had anal sex before?”

Sae clamped her mouth shut.

“I take that as a no.”

“Makoto,” Sae babbled, “I forgive you for everything earlier. I promise never to say a word of this to anybody. I will swear over our father’s grave that I will never hurt you again. Please, don’t do this!”

“I wish I could believe you…” 

Sae squealed as the head of her sister’s cock jammed against her little brown starfish. Her fists pounded against the wall as she began to feel her most private of muscles give way to the invading member. God, it felt like a baseball bat was being rammed against her hole. There was no way it could fit. Tightening her muscles, she fought to keep Makoto out.

“Let me make it easier for you,” Makoto whispered in her ear.

Suddenly her cheeks were pulled apart, the sudden movement startled Sae for just a moment, but a moment was all it took for her muscles to unclench and Makoto to ram herself inside.

She screeched, digging her fingernails into the drywall, and rearing her head back in agony. It felt huge, delving up her walls and jamming into her insides. Her sister wasn’t gentle about it either, taking both her meaty cheeks and sinking her cock as deep as she could with one thrust. The cum was barely noticeable as lube and Sae could only hope it’d be over soon.

“Oh, Sis!” Makoto whined, “You’re so tight! Keep squeezing me! Isn’t this great? We’re having our firsts together!”

Sae could only whimper as she was held still, her ass used as a fleshlight for Makoto’s cock. Soon her sister had wrapped her hands around her waist, almost like a hug. She started to pull out, and Sae hoped it was because she’d already cum, but to her dismay, Makoto started thrusting in and out of her like an inexperienced pup.

“Yes! Yes! Yes! Yes!” Her little sister bucked into her, humping her fat ass as it jiggled through her pants. Her small breasts pressed into Sae’s back, and she could feel her sister’s hardened nipples digging into her skin.

She was about to cuss at Makoto when it happened. A pang of pleasure radiated around her little ring. Like her nerves had suddenly been stroked by a feather. The pain was still there, but it was dulling, making way towards something else. Sae let out a grunt, her body betraying her as she felt herself back into one of Makoto’s thrusts. It felt…good. Somehow, an almost uncomfortably intense pleasure was building inside of her. 

“What…what’s…” Her knees felt like jelly and a tingling spread through her stomach. It was like a thousand butterflies had been released inside her and were flooding every part of her body. Her pussy screamed for attention like one of those butterflies had landed directly on her clit and was thrumming it gently.

“Ohhh,” Sae moaned, reaching down between her legs. Her fingers brushed Makoto’s hands wrapped around her stomach and she nearly pulled away, but instead, she dipped her hand further down to the opening in the crotch of her pants. Her fingers brushed her sex, and she knew she was dripping. Her hand went a little too low, and her fingernail grazed Makoto’s cock.

“I’m cumming! I’m cumming!” Makoto’s hug tightened as she squealed.

Sae’s mouth gaped, feeling a hotness welling up inside. This was the first time it’d happened, having someone cum inside her raw. Even if it was just her ass, it felt so…intimate. Like they’d become one. Maybe her mind was clouding, but as Makoto shot another healthy load inside her, Sae furiously jilled herself with her fingers.

“Forgive me…” Sae whispered to the memory of her father and slammed her hole back against Makoto’s cock while thrusting three fingers inside her needy cunt, hoping for just an inkling of the orgasm that’d rocked her sister’s body.

It didn’t take long, the boiling cum filling her snug hole was enough to push her quickly over the edge. Sae groaned, humping her hand and rolling her hips in hopes of filling herself just right. Arousal dripped from her knuckles as Makoto continued blindly bucking into her long after her balls were empty. Maybe it was being alone for so long or the frustrations from work, but Sae came quick and hard.

Her ears tingled and her vision went white as her orgasm tore through her supple body. She reached up, tugging at her cum covered nipples and licking the cream from her face. It was all a turn-on, everything about this was drawing her orgasm out longer and longer. It was like a perfect storm.

Coming down from her high, she realized Makoto had collapsed against her, exhausted. The two sisters were wrapped in an incestuous hug.

“I love you, Sis…” Makoto mumbled, slumping against her, “I love you…so much…”

She sounded just like a little kid.

Because… she was just a little kid, wasn’t she?

Sae sighed. Now she knew what to do.

But first, she needed a nap.

Makoto awoke; she was lying on the floor of the hallway. Her cock was soft again, a pool of old cum beneath it. At first, she thought it had all been a dream. That she’d slipped while running to the bathroom and knocked herself unconscious. But the hole in her tights, he cum on her skirt, it was obvious.

“Oh my God…” Makoto whimpered, covering her face with her hands. “What have I…I didn’t…”

A groan came from behind her, and she rolled over to see Sae crumpled on the floor.

“Sis!” She staggered to her feet, her eyes welling with tears, “I’m sorry, Sis! I didn’t…I…”

Sae didn’t respond, just holding her ass in obvious pain. Makoto sniffled; she’d hurt her. Badly.

She had to turn herself in.

“Don’t worry, I’ll make it right,” Makoto cried, starting towards the table where she left her cell phone. “I know where I belong now.” Behind bars. That’s where all the little freaks go.

Suddenly, a hand grasped her wrist and spun her around. Makoto’s eyes flew open as she was caught in a lustful and hungry kiss. Sae thrust her tongue into her mouth, and Makoto lost another first that night.

Sae pulled away, smiling at her younger sister, “You belong right here.”

“Sis?” Makoto asked, gasping as Sae’s fingers closed around her cock.

“You’re not a freak,” Sae said, gently stroking up her sister’s length. “I’ve been horrible to you, I’ve belittled you, and I was wrong. I think…I think we’ve both been stressed and exhausted and…pent up. But somewhere along the way, I stopped thinking of you as a little kid. You act so grown up sometimes that I forget I still need to take care of you.”

“Sisssss,” Makoto moaned as Sae stroked faster.

“So…you belong with me, I belong with you, but she…” she gave Makoto's dick a squeeze, “…she belongs to me now. And I’ll be giving her quite the workout from here on. Sounds fair?”

“Mmmhm,” Makoto whined.

“Good, because we’re taking tomorrow off,” Sae giggled, “you still have some cherries that need popping.”
