"Oi, Pikachu. The fuck are you doing?"
Kaminari yelped and dropped his shoes, completely fucking up whatever stealth operation he'd been trying to do. His shirt was on backwards too. And his neck was covered in red marks that would be hard as fuck to cover up.
And his room was definitely not on this floor of the dorms.
“B-Bakugou, my guy! And how are you on this fine morning?” He tried to play it cool, finger guns and everything, still holding onto the one shoe he picked up.
“Wondering what the fuck you’re doing and who you fucked.” Katsuki crossed his arms over his chest, watching Kaminari’s face light up in a red blush and he sputtered out a half-formed denial and excuse. Idiot probably forgot that Katsuki was the only one up and about at this time of day since he got up to go jogging.
And the only explanation for why Kaminari, of all people, would be up at the ass crack of dawn, sneaking out on the wrong dormitory floor, looking like his neck got mauled by a wild animal, was to meet someone for a fuck.
Kaminari rambled on about ‘sleepwalking’ or some shit to explain himself but Katsuki tuned him out in favor of trying to figure out who lived on this floor.
There was that weird-ass sparkle dude, the grape-head creep, the emo bird dude, and Deku. Katsuki immediately ruled out Sparkles and Grapes, which left him between Birdbrain and Deku. Birdy was quiet and reserved, and emo as hell, so Katsuki couldn’t imagine him hooking up with Kaminari (stranger things have happened though). So that only left…
“You were fucking Deku?”
Kaminari finally paused in his inane rambling to squeal and his whole face burned red.
“Ah! N-No! I mean-! It wasn’t a serious thing- I mean-”
Katsuki slapped a hand over his mouth, just to get him to stop talking. “Slow the fuck down or you’ll fuckin’ short circuit yourself and it’s too early in the day to deal with that.” Katsuki muttered, trying to keep his temper under control. He’d been doing good with keeping it in check, with therapy and all that shit, but this was seriously getting on his nerves and cutting into his workout time.
“Were you with the nerd or not?” Honestly, Katsuki didn’t know why he was so curious. It shouldn’t really matter to him but the thought of Deku somehow getting laid was a surprising thought.
With his mouth still covered by Katsuki’s hand, Kaminari’s shoulders slumped and he slowly nodded his head.
“Yeah, I was with Midoriya.” He confirmed once Katsuki pulled his hand away. “I didn’t mean to stay for that long but it was really good and I fell asleep and-”
Katsuki slapped his hand onto his mouth again, cutting him off more aggressively this time.
“Yeah, yeah. I don’t want the fuckin’ play by play of you fuckin’ the nerd.”
Kaminari pried his hand off of his mouth, smiling a little, cheeky grin. “Well, it was more like the other way around.”
“Hah? You let the nerd top you? You’re such a fuckin’ bottom, Pikachu.” Katsuki smirked at Kaminari’s offended “hey!” and walked around him, heading back towards the stairs. He still had some time to get a quick run in if he left now.
“Well it’s not like I’m the only one, ya’know!”
Wait a minute.
Katsuki stopped in his tracks and turned towards Kaminari again. “The fuck does that mean?”
Dunce Face blinked once or twice before the question set in. “What do you mean?”
“Oh my fucking god.” Katsuki pinched the bridge of his nose. His friends were morons. “What the fuck did you mean by ‘not the only one’?”
Kaminari blinked again after a long pause before recognition set in his face. “Ohhh!” And then it turned into a little sheepish sort of grin. “Well… I mean, I don’t know how many there are under his belt but I’m not exactly the first one to go to Midoriya for this kind of stuff.”
Katsuki was willing to chalk this up to Pikachu just being stupid again. He’s trying to tell Katsuki that Izuku ‘Deku’ Midoriya has apparently slept with more than one person, perhaps even more if Kaminari didn’t know how many were ‘under his belt’. It was a correlation that Katsuki couldn’t think of. Like, it didn’t make any sense.
“I’m pretty sure he’s been with, like, half the class, maybe?”
“He fuckin’ WHAT?”
~~~
"All right, no fuckin' lying. Who here has fucked the nerd?"
The amount of hands raised almost made Katsuki choke. A few were slow, hesitant. Some were confident, like they were absolutely stoked to admit it (Kaminari). Some went up only after seeing everyone else doing it.
The nerdy hero fanboy, Deku himself, had fucked over half of class 3-A and Katsuki is just now finding out about this. What the fuck.
It had been bugging Katsuki all damn day just wondering about it, wondering how many people Deku’s been with, ever since Kaminari put it in his head. Kaminari had cut their conversation (interrogation) short to go to nap in his room before classes and had left Katsuki there with a menagerie of thoughts and speculations.
The only way to get the nagging sensation to go away was to get some answers so Katsuki waited until late afternoon, when everyone else would be hanging out in the common area, talking and doing homework, to spring the question on all of them. It was just his luck that Deku was out at the moment, going for a walk or to the store or in a meeting with All Might, whatever the fuck he was doing.
He did not expect this answer.
He was not only shocked at the amount of hands, but the owners as well. Ururaka and Tsu shyly put their hands up around the same time. Icyhot raised his hand with his signature blank stare (and Katsuki almost laughed wondering if he was as deadpan in bed as he was in his daily life). The boring guy with the tail waited to see other hands before putting his up. Iida, sitting stock still in one of the armchairs, raised his stiff arm up after a while, which earned a few wide-eyed looks in his direction and his glasses hid his eyes but his pinks were noticeably dusted pink.
Kaminari’s hand went up as one of the firsts, unsurprisingly. The invisible chick sitting next to him was raising her hand, or at least it looked like she was (and Katsuki idly wondered what that must’ve been like). And, to his shock and horror, Kirishima sitting beside her raised his hand while rubbing the back of his neck with his free one and avoiding eye contact with Katsuki.
His fucking best friend had fucked Deku and hadn’t told him until now. Wow.
To his right, in their own little cluster on a couch, Sero, Mina, and Jirou all raised their hands with seemingly no shame whatsoever.
Had ALL of Katsuki’s friends been fucking Deku without him knowing???
Katsuki abruptly shut his mouth once he realized it was hanging open and attempted to get his bearings. He had not been prepared for this. He didn’t know what he was trying to prepare for but it wasn’t this.
“You seriously didn’t know, bro?” Kirishima asked, one hand still resting on the back of his neck.
“You shut your mouth, Shitty Hair.” Katsuki pointed directly at him but Kirishima just shrugged.
“He’s right, though. It was pretty obvious.” Jirou chimed in, idly twirling an ear bud around her finger, the other one still in her ear. “I’ve actually compared notes with some people.”
“Yeah, it was… interesting to learn about, but still fun.” Sero, the fucker, was just lounging in his seat, arms behind his head, while casually discussing sex notes with the others who’d slept with Deku.
“It was all pretty casual.” Ururaka said. “Some great stress relief when exams were coming up.” She was so weirdly cheerful about it. And the others apparently were happy to agree with her.
“I’ll admit, I had my reservations the first time.” Mina sat cross-legged on the couch, clutching one of her pink pillows to her chest. “But he was amazing! The things he can do with his hands…” She trailed off in a sigh, holding onto her pillow like it was a stuffed toy.
“God, don’t even get me started.” Kaminari practically had heart eyes thinking about the previous night. Katsuki remembered how disheveled he looked sneaking out this morning but quickly shook those thoughts out of his head.
“He had so much stamina, it was hard to keep up.” Shoto’s deadpan voice joined in on the conversation.
“Yes, Midoriya can be very… thorough.” Iida piped up for the first time, still with pink tinted ears. “I often wondered where he picked up his skills.”
“Practice most likely, ribbit.” Tsu put her finger up to her chin like she did when she was thinking. “If Midoriya has been with this many people, he’s probably been perfecting his techniques over the years.”
“He’s got that innocent, doe-eyed look to him, though! You’d never guess he was some kind of sex prodigy or anything like that.” Kaminari sounded like a lovesick (lustsick?) puppy. He still hadn’t covered up those marks around his neck and collarbone and Katsuki suspected that he must be very proud of them.
“Yeah, it kinda throws you off. But it’s like he always knows what to do.” Kirishima, the fucking traitor, ran a hand through his mussed up red hair and Katsuki noted the black roots he could see. “Like he always knew where to touch you and how to make it good. It’s like a gift.” He grinned, showing off his shark teeth with the pink tint to his face.
“Oh bull-fucking-shit.”
Every pair of eyes went to Katsuki, standing in front of them. Completely unimpressed.
“I’ve known Deku since we were kids. I’ve literally been there for every year of his life. He’s a hero fanboy nerd who still sleeps on All Might sheets. There is no. Fucking. Way. That he’s some kind of ‘sex god’.”
This had to be some joke. Some weird joke they wanted to play on him. Something to purposefully get under his skin. That had to be it. The only rational explanation.
“Hey, don’t knock it til you try it, dude.”
“Shut the fuck up, you fucking bottom.”
“Hey!”
Kirishima jumped in before it could escalate further and before Kaminari got more bruises in the shape of fists. “Come on, bro, Mido can’t be the same exact person he was as a kid.”
“Yeah! I mean, we’re third years. We’ve all changed. And Mido got all cute and buff.” Mina grinned slyly.
“And an ass that won’t quit.” Sero and her fist bumped and Katsuki wanted to smack them both.
“I still call complete bullshit. No fuckin’ way, you’re all delusional.”
“Sounds like someone’s in denial.”
“The FUCK did you say Icyhot?!”
“No fighting in the dorms! Aizawa-sensei has warned us enough times already!”
“Shut it, Glasses!”
Ochako finally stood and put her hands out in an attempt to calm the situation. “All right, that’s enough guys. Let’s calm down.” She then turned her sights back on Katsuki. “I don’t really know why you’re so curious about this, Bakugou, but we’ve been telling the truth the whole time. I guess Deku isn’t as innocent as you remember him.”
Why did they sometimes talk like Katsuki wasn’t in the same class as Deku? Like they hadn’t literally grown up together? Like he was still the shitty little brat that he was in their first year?
Katsuki knew Izuku. He knew him better than anybody else in this room, better than everybody in this world. That’s why hearing all of this shit was throwing him for a loop. It was like discovering uncharted territory in a place you called home for your whole life. It just didn’t feel possible.
“Like I said, bro. Don’t knock it til you try it.” Against all laws of common sense, Kaminari continued to open his mouth and let words come out.
“You tellin’ me I should fuck Deku? As fuckin’ if.”
“What? You afraid you might like it, hmm?” Mina looked like the cat that caught the canary. In fact, all of his friends did. Katsuki hated them. He had no friends, only traitors.
“You know damn well I ain’t afraid of shit, Pinky.” Katsuki huffed, hating that he was now under the scope for interrogation apparently.
“Bet you won’t go upstairs to Midoriya’s room right now and ask him.”
“He’s not even fuckin’ here, Ears.”
“Then we’ll wait until he gets home.”
Persistent little fuckers. This was supposed to get Katsuki some answers and now he’s being roped into some dumb shenanigans he wants no part of. Fuck it.
“Whatever. I got what I needed. I’m headin’ out.” He felt like he needed to let off some steam. It wasn’t late enough that the training rooms were closed, he could easily get an hour’s worth of training done before dark.
“Think on it, bro!”
“Shut up!”
~~~
Against his better judgement, Katsuki did think on it. A lot. A surprising amount in fact.
It was still so fucking weird to think of Deku as some kind of sex expert who banged half of their class right under Katsuki’s nose. It made him wonder when Deku changed and became way less innocent than Katsuki remembered. Just how many people, other than their class, has Deku taken to bed with him?
Why did he never ask Katsuki?
It ate at him the entire time he was in training. As much as he tried, he couldn’t get it out of his head. He wanted answers to his questions this morning and he was hoping that his nagging curiosity would be sated but it just kept poking and prodding at him.
He went through the routine of cleaning up, showering and putting on fresh clothes, before heading to bed. It was still early but damn did Katsuki feel fuckin’ tired. Laying in bed and waiting to fall asleep was impossible with his mind going a mile a minute. He felt tense and wound up; like he needed to get up and run or do something.
Katsuki didn’t know how he ended up in front of Deku’s door but he was knocking before he could talk himself out of it and go back to bed.
He knew the nerd would still be up at this hour. Doing homework or writing in one of his journals. Sure enough, Katsuki could hear some shuffling sounds from inside before the door popped open and Deku smiled at his visitor.
“Oh! Hi, Kacchan.”
“Yeah, hi.” Katsuki brushed past him on his way into the room, no invitation given whatsoever.
“Okay… come on in, then.” Izuku muttered while shutting his door.
Katsuki wandered to the middle of the room, turned to face him and crossed his arms over his chest. He still didn’t have a full clue on why he was here (a tiny voice in his head that suspiciously sounded like fucking IcyHot told him it was the denial but he promptly told it to shut the fuck up and take a fucking hike) but he was here now. Answers from the source.
“What are you doing here, Kacchan? Isn’t it a little late for you?” Izuku’s bright green eyes fixated on him and Katsuki was again thrown back and forth on how ‘innocent little Deku’ could have fucked half the class right under his nose.
“Shut it, nerd.”
Izuku tilted his head just slightly, like a fucking puppy. “Um… okay.”
They stood there in silence for about half a minute. Katsuki trying to figure out what to say and Izuku patiently waiting. He knew that it had to be important if Kacchan was staying up later than his usual bedtime to come see him.
“How many people have you fucked?”
What.
“What?” Izuku had to have heard him wrong. There’s no way Kacchan-
“I said, how many people have you fucked?”
Okay yeah, he did just say that.
“U-Uhh… C-Can I ask why you’re asking me this, Kacchan?”
“Answer the damn question, nerd. I’m tired of the fuckin’ runaround I’ve been getting all day.” Katsuki huffed. He looked antsy. It took Izuku a hot minute to shake off the shock of such a blunt question, from Katsuki of all people.
“Umm… I-I’m not sure, exactly.” Izuku reached up to scratch the back of his neck. “Um, K-Kacchan, why are you asking me this?”
Katsuki rolled his eyes. “Because I know you’ve fucked half the class by now and I’m wondering if you’ve got any other hookups that I don’t know about.”
Izuku felt his cheeks grow hot with a blush once it sunk in. “O-Oh. Yeah. That.”
He didn’t really keep it a secret, at least not at first. The things he did with his classmates was just for fun, for pleasure, and to unwind after a stressful day of school or hero training. Izuku often heard them discussing it with each other in side conversations, which was a little weird to think that they were all talking about him in such an intimate way but Izuku didn’t really mind it. It was kind of nice, actually.
He’d never expected Kacchan to be the one to ask him about it, though.
“W-Well, I mostly just do it for stress relief. I guess word got around about my, uh… ‘skills’, and one thing led to another.” He shrugged as a way of explanation, still feeling the hot blush on his face. “I didn’t even realize how many people were, uh, c-coming to me for ‘that’.” His face felt even warmer, which was embarrassing but that only served to make him feel more red.
Katsuki narrowed his eyes at him and Izuku suddenly felt like he was under a microscope. Like Kacchan was picking him apart and studying him, but for reasons Izuku still had no clue about.
“Okay, no.” Katsuki shook his head and dropped his arms to put his hands on his hips. “Hell no. No fuckin’ way. This is some kind of joke, right?”
Izuku blinked at him, still unable to read Kacchan like he normally was able to. “N-No? I don’t know what you mean, Kacchan.”
“There ain’t no fuckin’ way you’ve banged that many people. That’s literally impossible.”
He didn’t know why but Izuku suddenly felt a little offended. “Why would that be impossible, Kacchan? I’ve had sex before. A l-lot of it, actually.” He didn’t know why he was saying this, it was embarrassing, but he also didn’t know why Kacchan was barging into his room late at night to question him about his sex life.
“Bullshit. You’re literally as innocent as they come. You’re the fuckin’ textbook definition of innocent.” Katsuki looked him up and down and then glanced around his room, where his hero posters and figures still stood. Not as many since he’s grown up a bit, but still a number of them.
Izuku frowned and copied Katsuki’s earlier stance by crossing his arms in front of his chest. “I’m not a little kid anymore, Kacchan. I’m not as ‘innocent’ as you might think I am.”
“Ha! Yeah right.” Katsuki grinned at him. “Ain’t no fuckin’ way you’re foolin’ me, Deku. I know you too well for that.”
Izuku didn’t know why but hearing Kacchan question his virginity was more annoying than he initially thought it was going to be. It was true, he wasn’t a little kid anymore. He’d had his fair share of late night rendezvous and he knew for a fact that Kacchan had as well. Why did it make sense for Kacchan to sleep around and Izuku couldn’t do the same?
Fine. If Kacchan wants proof, then he’ll get proof.
“You want me to show you?”
“Hah?” Katsuki actually looked taken aback. “The fuck you mean, nerd?”
A part of Izuku’s brain told him this was a bad idea and to abort before it was too late but the stubborn part of him really wanted to prove Katsuki wrong.
“I mean I can show you right here and now that I’m not ‘innocent little Deku’ anymore.” Izuku smiled somewhat coyly at Katsuki, a smug glimmer in his eye.
That’s a challenge if Katsuki’s ever seen one. And he’s never backed down from a challenge, no matter what kind it was.
“All right, you’re fucking on, Deku.” Katsuki casually strolled over to Izuku’s bed and laid down, already getting comfortable with his arms behind his head. “Prove it then.”
Izuku could already feel that low heat in his belly as he dimmed the lights in his room, turned to his door, and twisted the lock in place.
For some reason, the click of the lock sent something warm through Katsuki.
Izuku was wearing a pair of UA styled sweatpants that he kicked off before climbing into bed with Katsuki. He hovered over him, not really straddling his hips, like he was trying to find the right position.
“Get on with it, Deku. Don’t have all night.” Katsuki grunted while watching him maneuver onto the bed.
Izuku rolled his eyes and decided to move on before Katsuki could snipe at him for that. “Ground rules, Kacchan. What are you okay with?”
One eyebrow raised at Izuku’s question. “The hell do you mean?”
“I mean, what are you comfortable with? Do you want me to kiss you or touch you in certain places? Or places where you don’t want me to touch?”
That sounded… rehearsed. But Katsuki didn’t want to dwell on that train of thought for too long.
“Whatever, nerd. I don’t care. Just get the show on the road.”
Apparently with their boundaries all set, Izuku finally relaxed and settled down on top of Katsuki, sitting on his hips with his legs straddling him. Deku was heavier than Katsuki remembered but it was still a warm weight on top of him.
And then Izuku was leaning in and kissing him before Katsuki could even blink. It startled him for a moment before he relaxed into it. Deku’s lips were softer than they looked and he took advantage of catching Katsuki off guard to swipe his tongue along his top lip to get him to open up. It didn’t even register in the back of Katsuki’s mind that he was currently making out with his childhood friend/rival.
He was so distracted by the kiss that the hands suddenly crawling up his shirt made him shiver involuntarily. Izuku pulled away so they could both breathe but there was that smug look in his eyes at knowing that he had the upper hand. Katsuki glared at him but the effect was probably nullified by how darkened and wet his lips were.
Little shit just caught him off guard. It’d been a while since he’d been in bed with someone.
Izuku’s hands felt rough but they were so light against Katsuki’s skin, like they were barely brushing against his stomach under his shirt. It felt like Deku was tracing his abs or massaging his thumbs into them.
“You’ve always been so strong, Kacchan. Wish you would go shirtless more often so I could see it.” Izuku murmured as his hands wandered along Katsuki’s chest. “You know, like Kirishima? His body is always out and on display. Can’t say I don’t enjoy it.”
Katsuki had never heard this tone of voice from Deku before. It sounded low but loud in the quiet room and he sounded so coy, like he knew exactly what buttons to push and in what order. And he was definitely pushing a button; it was pissing Katsuki off to hear Deku talk about Kirishima at a time like this.
“Weird fuckin’ foreplay to talk about Shitty Hair right now, Deku. Thought you were trying to ‘enlighten’ me or some shit?” Katsuki challenged him with a smirk, practically laying out the bait for Izuku to take. He was all talk, Katsuki knew it already. He just needed to bust through the façade Deku had put up.
But Izuku’s hands slowed to a stop under his shirt, resting against Katsuki’s stomach. Katsuki always ran warm, a side effect of his quirk, but he could still distinguish Izuku’s heat from his own. It was a weird feeling.
“Getting jealous, Kacchan? You don’t like hearing me talk about how much Kirishima loved when I told him how I just couldn’t get enough of his abs?” Izuku smiled, looking down at Katsuki. His fingers started to move again, slowly moving up his chest and towards Katsuki’s pecs. “From what I remember, Kiri really liked it when I did this.”
The tips of his fingers brushed against Katsuki’s nipples and he felt himself tense up involuntarily. It was just gentle brushing, barely a real touch, but it still sent weird zaps of feeling down his spine. Katsuki had never been touched there before, never really saw the point to it. Didn’t think he would be so sensitive there.
Then Deku brought his fingers up to gently pinch Katsuki’s nipples in between his fingertips and Katsuki bit his tongue to keep from making any noise. It felt so weird, but in a good way.
“Do you like that, Kacchan? Are you sensitive here?” Deku kept gently rolling his fingertips over his nipples until they were hard and so obvious through his thin shirt. “You’re squirming.”
“Shut up you fuckin’ nerd.” Katsuki said through gritted teeth, now painfully aware of his fingers digging into the bedsheets. He wasn’t squirming, Katsuki Bakugou didn’t fucking do that in bed.
He just… wasn’t expecting this, that’s all. Deku just had a weird fascination with nipples or something and Katsuki had never been touched there before and-
Katsuki bit down on his lip when Deku suddenly gave a hard pinch to his nipples, completely derailing whatever thoughts he was having before. That felt so fucking weird. But it felt… good?
He heard Deku giggling above him and looked up to see him grinning down at Katsuki. “You like it, Kacchan.” It was a statement, not a question. Katsuki felt the heat on his face and knew that Deku could see it too, which he fucking hated.
Izuku’s fingers finally pulled away to give his nipples a break, sliding back down his chest and all the way down to the hem of his shirt, where he lightly tugged in a silent request to take it off. He pulled his hands back long enough for Katsuki to reach down and yank his black tank top off, tossing it somewhere in the room.
Izuku hummed in appreciation once Katsuki’s chest was fully revealed. “Wow. You look amazing, Kacchan.” His voice was hushed but earnest. It made that part of Katsuki’s ego purr with delight.
He opened his mouth to brag and boast but Izuku beat him to it, taking advantage of the perfect timing to stick his tongue in his mouth. Katsuki would be more pissed about it if it wasn’t so good. This fuckin’ nerd and his stupid fucking soft lips and his stupid tongue trying to map every inch of Katsuki’s mouth. Fucking dick.
Izuku could feel the heat travelling through his body, already becoming overheated in the bare clothing he had on. Katsuki’s body was so warm, like a heated blanket. Kacchan had always been so warm and Izuku loved it. It made him want to strip down to his bare skin but he still had some patience left in him. He would wait as long as he possibly could, just to get under Kacchan’s skin. If Kacchan wanted a good time, he was gonna get it.
He slowly drifted his hand downwards, taking the opportunity to brush against Katsuki’s muscles once more. He couldn’t help it; Kacchan just looked so good like this. He felt his fingers lightly touch the waistband of Katsuki’s sweats and just beneath that he could just barely feel the bulge of Katsuki’s half-hard cock.
It made Izuku smile into the next kiss. He loved hearing that sharp inhale as soon as his palm grounded down against it.
“Mm, you’re already getting hard for me, Kacchan.” He could see the way Katsuki grit his teeth and kept eye contact with him but his cheeks were so flushed, it was adorable. “You really like this, huh? Ready to admit it yet?”
Katsuki’s eyes flared in annoyance as he glared up at Deku. “As fuckin’ if, Deku. Just cuz my dick’s getting hard doesn’t mean you’re some fuckin’ savant or some shit.”
It did feel really good, though; having those fingers trace the outline of his dick through his underwear and occasionally a palm grinding down for the stimulation he needed. He knew he had to be nearly rock hard by now but like hell he would ever admit that it was Izuku’s handiwork that did it. It’d just been a while since he got his rocks off. He didn’t have time for a fuck buddy and his hand did a quick job most nights when he felt the energy to.
Izuku lightly gripped Katsuki through his underwear, feeling the throbbing heat hidden away by just a thin layer of cloth. It made the warmth in Izuku’s belly rise and his face grew hot. Katsuki felt so big, the absolute perfect length. Of course, Kacchan was perfect in every way.
He leaned into Katsuki’s neck at the same time his fingers finally slipped under Katsuki’s briefs and grabbed his dick, savoring that sharp hiss right in his ear.
“You feel so big, Kacchan. Feels like I can barely get my fingers around it.” Izuku huffed some quiet laughter at how tense he could feel Katsuki under him. “You’re so hard. I bet this cock would feel so good inside of me.”
Katsuki resisted the strong urge to buck his hips into Deku’s hand. When did the nerd learn to talk like this? And his fucking hands; it felt like they were everywhere, touching everywhere. He couldn’t stop the images that popped into his head that made him throb. The thought of sticking his dick into a tight, wet hole sounded like fucking heaven right about now.
He felt teeth on his neck at the same time a hand started slowly stroking his cock. Katsuki gasped at a harsh bite over his pulse and shut his eyes tight. The combination of sharp teeth at his neck and gentle squeeze to his dick brought a hot flush of sweat to his hands and the sharp scent of burnt sugar.
Without thinking twice, Katsuki gripped Izuku’s hips and pulled him closer, forcing Izuku’s hips to grind down on his and relishing in the cut off moan in his ear. He could feel the strong muscle under his clothes.
“We gonna hurry the fuck along or are we gonna dry hump like virgins all night?” Katsuki snapped, feeling the annoying throb of his dick.
Deku smiled down at him with a look like he knew a secret that Katsuki didn’t and sat up. Their dicks brushed against each other in their underwear and it felt good but it wasn’t enough. Izuku lifted the hem of his shirt over his head, giving Katsuki a good view of his body.
One thing that definitely changed over the years was Deku’s body. Katsuki couldn’t deny how fit and toned he’d gotten thanks to the extensive training he’d gone through. His arms were bigger with muscle and his torso had filled out nicely, all toned and perfect looking. His abs looked hard to the touch and it all led to a perfect trail down to his hips, with his underwear riding down just low enough to hide his cock but show off the ‘V’ of his hip bones.
Katsuki had the sudden urge to nip and bite at them and tear off Deku’s stupid underwear keeping them from moving on, but he still resisted. Every competitive nerve in his body was telling him to not let Deku win, to prove that he wasn’t stupidly good at sex and he couldn’t sway Katsuki like he’d already done with half the class.
Izuku’s shirt was tossed somewhere on the floor of his room and then he leaned back down, lips barely brushing against Katsuki’s as his hands traveled back onto his chest and pressed against his pecs.
Izuku nibbled on his bottom lip while his fingers traced the lines of Katsuki’s abs. “All that hard work really paid off, Kacchan. You look so amazing.” He sounded in awe of Katsuki’s body and it only stroked his ego more. “Not that I’m surprised. Kacchan always looks amazing.”
“What else is new, Deku?” Katsuki muttered, half waiting for Deku to get on with it and half expecting him to keep waxing poetry about his fuckin’ six pack.
Izuku rolled his eyes. “Not like you aren’t enjoying all this attention, Kacchan. You’re rock hard.” One hand went back to groping Katsuki through his boxers and Katsuki hissed when he squeezed.
“No fuckin’ duh, I’m hard. You’ve literally got my dick in your hand. So get a fuckin’ move on.” Katsuki’s patience was quickly running thin. Not like he had a lot to begin with, but it was getting more and more scarce by the second. If Deku didn’t get him off soon, he’s liable to kick him off, walk back to his room and jerk himself off. At least he’d actually get an orgasm out of that.
“Ugh. So impatient, Kacchan.” Izuku pulled away so abruptly that it left a chill on Katsuki’s heated skin. He shuffled backwards so he was no longer sitting on Katsuki’s hips and lowered his head to his pecs. “I like to take my time, Kacchan. Feels better that way.” He could feel his hot breath on his skin right before his teeth dug in and nipped at his stomach.
It was a weird sensation, not really unwelcome, per say. Deku was surprisingly gentle and it almost tickled, but Katsuki remained still. His fingers curled into the bedsheets, just to give them something to hold onto so he didn’t feel like he was scrambling for something to do.
Izuku kept nipping, biting and kissing his way down Katsuki’s body, getting closer and closer to where his dick was. He stopped right before the waistband of his underwear and eased a finger under the elastic, very lightly tugging on it while making eye contact with Katsuki. His fingers reached down lower and lower until he finally grazed Katsuki’s hard cock. It felt hot to the touch and Izuku couldn’t help but shiver at the thought of it inside him.
The tension in Katsuki’s body made him feel stiff but the touch to his dick made him jolt a little. He was finally touching him but he still moved at a snail’s pace and it was driving Katsuki insane. His dick was throbbing consistently and he even tried nudging his hips a little to get Deku to take the hint but the insufferable nerd kept teasing him; running his fingers up and down the length of his dick, practically sizing him up.
“Oh, for fuck’s sake!” Katsuki sat up quick and reached down to tug the waistband of his underwear down himself, letting his cock spring free of its confinement and almost hitting Deku in the face.
It actually seemed to startle him. He let out a little “oh” when a dick almost hit his cheek but it quickly turned into admiration.
“Not bad, Kacchan.” He grinned, finally wrapping a hand around the base of his dick and giving it a slow stroke, thumb brushing the head and swiping up a small bead of precum. It made Katsuki jolt at the bare touch.
Izuku slowly squeezed and stroked Katsuki’s dick; starting from the head, all the way down to the base and then back up to the head. It felt hot and heavy in his hand. It was almost funny that even Kacchan’s dick looked and felt perfect.
Izuku nibbled on his bottom lip in anticipation of getting to have that perfect dick inside him. But, he wanted a little taste first.
His tongue stuck out to lap up the beads of precum at the tip of Katsuki’s cock, preening at the sharp inhale above him. He knew Katsuki would be too proud to admit that Izuku was actually doing a good job, but that just made it more fun to take him apart, bit by bit. Katsuki was a challenge and Izuku loved a challenge.
Izuku looked up to make eye contact with Katsuki as he took the head of his cock in his mouth. He felt it throb on his tongue as Katsuki flinched and Izuku could see the red flush on his cheeks even in the dim lighting of his room. He lightly swirled his tongue around the head, lapping at the precum and honing in on the grunts and moans Kacchan was trying to hide behind clenched teeth.
Katsuki was a pretty good size so Izuku couldn’t take him all at once, as much as he really wanted to, so he started slowly taking more and more into his mouth. He was only halfway down when he felt Katsuki’s hips twitch and he knew he was fighting back the urge to fuck Izuku’s mouth. His own cock throbbed at the thought but Izuku focused all of his attention on taking every single inch of dick into his mouth.
It felt like hours went by until he finally stopped at the base, right at the patch of neatly trimmed, blonde pubic hair. He could feel Katsuki’s cock down his throat and he swallowed around it, almost gagging when Katsuki involuntarily thrusted and made Izuku take even more.
“S-Shit, Deku.” Katsuki muttered, sucking in a sharp breath when he felt Deku's wet tongue pressed up against his dick and slid up as Deku lifted his head. He started a slow rhythm of bobbing up and down, taking Katsuki’s entire cock down his throat at once.
“Guess you really are a cockslut, huh?” Katsuki grinned down at Deku, making eye contact just as he started swirling his tongue around the head of his cock. “Gotta admit, feels fuckin’ good. Took it all in one go, too. Not bad, Deku.”
Izuku sank back down, swallowing every inch he could take and blinking back the wetness in the corner of his eyes, but he pushed himself just a little further to hear Katsuki choke on a moan and toss his head back.
He was about to lift his head when a hand firmly gripped his hair and pushed him back down, holding him there with Katsuki’s dick in his throat.
”Fuck.” Katsuki hissed, fingers tightening in Izuku’s curls. “Think I could come right now, Deku. Teased me so fuckin’ much.” Katsuki let out a shaky breath and looked down at him. “You spit or swallow?”
Katsuki let go of his hair so he could answer. Izuku lifted his head up, sucking in a deep breath and leaving a trail of saliva from his lip to Katsuki’s dick. He took a moment just to breathe and try not to get distracted by the throbbing of his own dick still covered by cloth and pressed against the mattress.
“As much as I would love to make you come in my mouth,” Izuku smiled up at him and wiped some drool off of his cheek. “I’m getting impatient. And I think I’ve made you wait long enough.” He sat up and stood from the bed to reach into his nightstand to grab a bottle of lube and a short roll of condoms.
Izuku tossed his items onto the bed on the other side of Katsuki and pulled his underwear off, sighing in relief once his cock was free. It made him feel a little more smug once he noticed Katsuki’s eye roaming over his body.
He crawled back in bed, knees on either side of Katsuki’s legs, and reached for the bottle. He poured just enough to coat his fingers, being careful not to spill any, and reached down to gently rub over his hole.
“Oh, and for the record, I do swallow.” Izuku pushed one finger in and bit his lip to stifle a moan. He was still a little loose from this morning when he’d played around with a toy.
It didn’t take long for Izuku to reach up to three fingers, thrusting inside and stretching himself out. Every brush to his prostate had him shivering and moaning, but he was careful enough only to tease himself. He wanted to come with Kacchan’s beautiful cock inside him.
Katsuki watched the scene in front of him, practically enraptured by the way Deku’s fingers moved and the little sighing moans he made. He couldn’t resist grabbing his hips, gently squeezing and rubbing his thumbs along his pelvis. It almost made him moan aloud just imagining grabbing these hips hard enough to bruise and pounding Deku so hard the entire dorm could hear his bed frame shaking.
At first, he was apprehensive. When he woke up this morning, Deku was a scrawny, virgin nerd. And now Katsuki’s seen a strong and fit Deku that sucked dick like a pornstar and fingered himself good enough that it made Katsuki throb and twitch even without anything touching his dick. Ask him an hour ago if he would fuck Deku and he probably would’ve exploded your face. But now he was practically desperate to shove his cock deep inside him and fuck him hard enough that Deku would feel him for weeks.
Izuku finally pulled his fingers out with a quiet whine and reached over with his clean hand to grab the string of condoms, tearing one off the strip. He was about to toss it to Katsuki but he hesitated, looked between the condom and Katsuki, and then tossed it aside along with the other condoms.
Katsuki watched the condoms get thrown across the room and looked up at Deku with one eyebrow raised. “The fuck was that about?”
The corner of Deku’s lip went up slightly as he crawled forward, resting his hands on Katsuki’s chest and straddling his waist. He got close enough to press a feather light kiss to Katsuki’s mouth and leaned further in to brush his lips against his ear.
“I’ve been waiting so long for this, Kacchan. I wanna feel everything you can give me.” His hips grinded into Katsuki’s still hard, still leaking dick and Katsuki didn’t even try to hide his shiver. The thought of coming inside of Deku, the thought of Deku even thinking about being stuffed with Katsuki’s cock, almost made him come undone right there.
He needed to fuck him. He needed it so bad. He needed to have him right now.
With an impatient growl, Katsuki grabbed Izuku’s hips and lifted him up slightly to get his cock out from under them and press it to Deku’s hole. It felt wet and soft and ready for him.
Just as he was finally finally about to plunge deep inside that tight hole, Deku grabbed Katsuki’s wrists and with a small flash of green sparks, pinned his arms above his head to the headboard of the bed. His eyes shimmered a bright green in the darkness of the room and the sudden show of strength made Katsuki buck his hips and whine from impatience.
“I don’t think so, Kacchan.” Deku grinned at him as his voice slid into a deeper tone that Katsuki couldn’t ever remember hearing before (but would forever deny that it made his dick twitch hearing him talk like that).
“I want us to make one thing clear while I’m fucking your brains out.” His hips slowly lowered again until Katsuki’s dick pressed lightly against his hole, just barely entering him. “You’re not in charge here. I am.”
And then he suddenly dropped his hips and slid almost the entirety of Katsuki’s cock inside of him. Both of them let out loud moans of pleasure as Izuku took more of him, lowering himself at a slow, crawling pace. He was almost at the base of it when he lifted his hips and dropped back down, starting a steady and slow rhythm as he rode Katsuki.
Katsuki let his head fall back, banging it against the headboard with a dull thud, as Deku slid further down. It felt so fucking good, Deku was so tight and wet and Katsuki fit him perfectly. Even with all the lube and the prep, he still felt so tight and Katsuki nearly choked when Deku squeezed around his dick inside him.
”Mmmmm, Kacchan… you feel so big…” Deku let out a breathy sigh as he paused with Katsuki’s cock fully inside of him. He didn’t know how many times he’d thought about this exact moment, what Kacchan’s cock would feel like in his hands, his mouth, his ass. It was so much better than he ever could have dreamed. He could feel the weight in his stomach and it made him feel warm and tingly.
“Holy fuck, Deku.” Katsuki grunted, practically focusing all of his willpower not to come immediately and ruin it. He could feel himself throbbing and wanted so, so badly to just grab him by the hips, flip him over and fuck him until neither of them could move.
“Come on, you shithead! Move!”
Deku giggled under his breath and lifted his hips again. “So demanding, Kacchan. I love it when you’re bossy.” He then began a slightly faster rhythm of fucking himself on Kacchan’s dick.
The room was filled with the sound of skin slapping against skin and the creaking of the mattress springs intermingled with breathy moans and sharp swears. It was hot and smelled of burnt sugar. They were wet from the combination of lube, sweat and spit.
Deku deliberately clenched around him every time he lifted his hips, always keeping him in a tight, wet vice that was slowly driving Katsuki mad. His knuckles bumped against the wall every time the bed lurched and he dug his nails into his palms once he realized he couldn’t break Izuku’s grip on him. No matter how badly he wanted to grab at him; not just to toss him over to fuck him properly but just to touch him. Bruise his hips and thighs with fingerprints, cover his chest and neck with bite marks, pull and tug on his hair. Katsuki couldn’t take just sitting there and doing nothing while Deku used him like a toy.
Not that he necessarily minded. The only good thing was that the view of watching Izuku bounce on his cock and make those pretty little noises was amazing and Katsuki could probably watch for hours and never get bored.
“Oh, Kacchan…” Deku sighed, eyes fluttering closed as he kicked it up a notch and went a little faster. Katsuki could tell when he found the right angle when his fingers clenched around Katsuki’s wrists and he got impossibly tighter. “You feel so- a-ah, so good. So good.” He whispered in between sharp moans.
Katsuki clenched his teeth and breathed out slowly to focus entirely on not coming. It felt really fuckin’ good, and as much as he would love to have a mind-blowing orgasm and creampie Deku at the same time (no don’t think about that Katsuki not yet don’t come don’t come don’t come), he wasn’t ready for this to end just yet. Edging had always been a big thing for him and Katsuki held onto enough self-control to keep himself still and willing to let Deku do the work. For now.
When Izuku opened his eyes, they immediately trailed over Katsuki’s flushed, sweaty face and down to his equally sweaty body. He didn’t know just how much he needed to have Kacchan under him until now. Well, he’d had fantasies about it but fantasy and reality were completely separate things.
His grip on Kacchan’s wrists were starting to slip. When Izuku slammed his hips down particularly hard, Kacchan’s fingers tightened into his palms and the sharp scent of caramel hit him like a brick. He spent a few long moments just staring at Kacchan’s hands in front of him until an idea suddenly struck him.
Izuku rearranged their hands to press his thumbs against Katsuki’s palms and delighted in the surprised jolt from under him.
“Deku, wh-”
Izuku pressed down on his palms and rubbed in a hard clockwise circle and felt the full body shiver from Katsuki. Another circle and Kacchan made a strained, whining noise that Izuku had never heard until now.
“W-What the fuck, Deku!” Kacchan’s wide eyes looked from Izuku to where his hands were forced up against the wall. His cheeks were flushed red, almost as dark as his eyes.
“What is it, Kacchan? Are you sensitive here?” Izuku murmured, applying just a little more force against Katsuki’s wrists and delighting in watching him twitch and moan. “I guessed a long time ago that your quirk makes your hands sensitive, but now I finally get to test it. This is so much better than I could’ve hoped for.”
Katsuki opened his mouth, probably to bitch out Deku or something of that caliber, but his mouth went slack as his eyelids fluttered shut when Izuku applied more pressure. His touch was feather light but it felt like he was holding him in a vice grip.
Why did it feel so fucking good?!
“Ah- Deku, you- ah, shit!” Katsuki’s fingers twitched uncontrollably as Izuku made slow circles on his palms. “H-How-how did-?” He could barely fucking speak; there was just too much stimulation.
His hands tingled in all the right ways from Deku’s ministrations. His cock felt hot and Deku squeezed him so good on every thrust. His hips were gonna be bruised from how hard Deku was fucking bouncing on his dick. He couldn’t tell if he wanted to beg for more or beg for it to stop.
Izuku’s rhythm suddenly stuttered and he let out a choked gasp, his hands involuntarily gripping Katsuki’s palms tighter and forcing a whine out of him.
”Aaahnnn, Kacchan!” His voice cracked as he tossed his head back, hips grinding furiously against Katsuki’s. “Fuck, I’m close. I’m so close, I’m- hah, I’m gonna- Kacchan!”
’God, yes, finally, please.’ Katsuki mentally pleaded for Deku to come already. He couldn’t take it anymore, he was at his peak.
Deku’s high-pitched moans grew louder and louder until he cried out Katsuki’s name and froze, his body shuddering and tightening as he sprayed both his and Katsuki’s chest with his load. He clenched around Katsuki and pressed his nails into his palms at the same time and the weird pain/pleasure feedback loop immediately sent Katsuki over the edge. His hips bucked upwards on their own and he slammed further into Izuku’s body as he filled him up completely.
Katsuki swore that he stopped breathing for a good few seconds. His vision whited out and his toes curled as he had what was possibly the best and longest orgasm he’s ever had in his life. He didn’t know where he ended and Deku began.
Once Izuku stopped shaking so much, he dropped Katsuki’s wrists and let his arms fall as he fell forward onto his chest. It was gross and sticky with his cum all over them but neither of them were in a position to care. Their bodies were sensitive and numb and definitely overheated but too exhausted to move. Katsuki barely registered the fact that he had full control over his arms yet again.
It must’ve been minutes but felt like hours until Izuku regained enough energy and strength to roll off of Katsuki and land on the bed beside him, limbs spread out and mimicking Katsuki’s pose. They still didn’t say a word; just focused on catching their breath and waiting for feeling to come back to their bodies.
“Well,” Izuku swallowed and cleared his throat, knowing it was going to give him hell tomorrow morning. “What did you think, Kacchan?” He lazily turned his head to the side to see how Kacchan was faring.
Katsuki was laying with one arm over his eyes, looking dead to the world. Izuku knew he wasn’t asleep yet because his breathing was still uneven and heavy. It seemed like it took a while for his question to register and Kacchan dropped his arm to the side, eyes slowly blinking open to stare at the ceiling.
“What… the fuck?” Kacchan sounded drained but more relaxed than Izuku had seen him in a while. His head tilted in Izuku’s direction but his gaze looked distant. “What… the fuck?”
Izuku giggled under his breath. He was exhausted but knowing that he’d fucked the thoughts out of Kacchan was such a huge ego boost.
“Not so innocent now, am I? I told you so.”
“Shutthefuckup.”
Katsuki’s arm slowly and lazily reached out to smack Izuku’s chest and then kinda rested there. It felt a little nice, even though they were both hot and sweaty and kinda gross. Izuku had some towels somewhere in his closet and water bottles they could use but he couldn’t get up right now even if he tried.
Just as he was trying to find the motivation to stand up, Katsuki’s hand still on his chest moved upwards until he grabbed a handful of his hair and Izuku had to bite back both a wince and a moan.
“Give me a few more minutes… and I’m gonna fuck you up, Deku.” His deep red eyes were suddenly looking right at him and Izuku didn’t know where this sudden burst of energy was coming from but he was far from complaining.
His body was going to hate him tomorrow, but it would be entirely worth it.
~~~
It was way past his usual alarm to get up but it took every ounce of energy left in his body to get Katsuki out of bed.
He really didn’t want to; Deku’s bed was nice and warm and the nerd had tried to entice him with these sleepy kisses that drew him further in. But he was sore and in dire need of a shower, so he had no choice but to get up and get dressed.
He also wanted to get back to his room before any of their other classmates were up and about and ready to question him invasively. Him sleeping past his morning alarm was suspicious enough but him walking away from Deku’s form floor would be the nail in the coffin.
Katsuki left with promises of coming back later that night (no fuckin’ way was it going to be a one and done thing; that ass was his now, the extras can go fuck themselves) and quietly slipped out the door with only the slightest creak. It was early and bright but still just early enough that hopefully he could make it to his room and down to the showers without running into anybody.
Except he turned the corner and immediately ran into Dumb and Dumber.
“Ayyy, morning Bakubro!”
“Well that’s weird. This doesn’t look like your floor.”
Kaminari and Kirishima had twin sly grins on their faces. It made Katsuki want to cremate them on the spot.
“Not. A fucking. Word.”
“I told you you’d like it if you tried it.”
”I’m going to kill you.”
~~~
(“I don’t know, man. This feels creepy.”
“Don’t worry about it, my guy. We’re not gonna stick around, I just wanna listen in a little and see if anything’s going on.”
“That’s still weird, man. Feels like we’re invading Midobro’s privacy. What if they’re not even in there and he comes out and catches us just standing outside his room like-”
“Shh! Did you hear that?”
“Hear what?”
”Shh!”
A steady thumping rhythm could be heard from the wall beside them. If they listened close enough, there was a distinct high pitched voice crying out for something but it was too muffled to hear.
”See?! I knew it!”
“Dude, be quiet! How do we even know that’s Bakugou in there?”
Kaminari’s response was immediately cut off by a rather loud thump on the wall and a deeper voice yelling out obscenities mixed with ”Deku!”.
“...”
“...”
“I’ve never felt so validated until this very moment. I’m gonna rub it in his face tomorrow.”
“What flowers do you want at your funeral then?”)
