“Oye, are you gonna get in the fuckin’ car or what, Deku!?”
Izuku jumps at the familiar voice, shoulders hunching on instinct as he turns. Sure enough, there’s Katsuki in his sleek black car by the school entrance, very obviously waiting on Izuku.
Sheepishly, Izuku says goodbye to his friends and then runs to get into the car. If he just walked it’d earn him even more ridicule. Katsuki has never been a patient man, not when he was younger, and not now that he’s hit twenty-five and Izuku has started making fun of him for his advanced age.
“You know you don’t have to yell at me,” Izuku says as he slides into the passenger seat. The door has barely closed, his fingers only having brushed the seat belt before Katsuki is pulling away from the curb with far too much speed. Years of sitting in this exact seat have gotten Izuku used to it though, and he barely blinks twice as he’s jostled.
“I do if I don’t want to be sitting around waiting on your slow ass for fuckin’ ever,” Katsuki snaps in reply, though his words lack any actual heat. “I liked it better when you had no friends. Now that a few people actually put up with you, you never shut the fuck up.”
Were he anyone else, Izuku might be offended by the words. But it’s Kacchan, the older boy from next door who used to babysit Izuku when they were kids. Then he was the highschooler who helped Izuku with his homework, and let Izuku stand on the pegs of his bike. Now he’s an adult and has moved out of his parents’ house but he still picks Izuku up from school a few times a week.
Izuku’s kind of a little bit in love with him? Maybe a lot of bit. And has been since he was five and Katsuki was fifteen and showing off his superhero action figure collection.
“Don’t be a dick, Kacchan.”
“Hey, watch your fuckin’ mouth, kid!”
“Dick isn’t a bad word and also I’m pretty sure you’re the one who taught it to me,” Izuku snarks back, sticking his tongue out at Katsuki. Not that the blond can see him, considering he’s driving. But it’s about the principle of the matter.
“What are you, a toddler? Don’t blame me for your bad behavior.”
There’s another retort on Izuku’s tongue, something about how Izuku wishes he and Katsuki could get up to some bad behavior. But some things are better left unsaid, and his crush on a whole ass adult man is one of those things.
Maybe one day when he’s older Katsuki will actually be able to see something other than an annoying kid in Izuku. Maybe they’ll lose touch for a little while when Izuku goes off to college, then he’ll come back to visit his mother one day and coincidentally Katsuki will be visiting his parents too and they’ll shake hands and Izuku will say, “Hey Kacchan, it’s been a while,” and Katsuki will be perfectly silent because he’s so shocked by how handsome and adult Izuku is now and-
Izuku shakes the daydream out of his head, cheeks flushing. It’s one thing to think up embarrassing, silly scenarios in the middle of the night. Another entirely to do so while sitting next to the subject of said daydreams. Hopefully Kacchan won’t notice.
“What’s got you turning red?” the blond asks, ruining all of Izuku’s hope. “Thinkin’ something dirty over there you little perv?”
“Kacchan!” Izuku squawks, somehow managing to get even hotter and redder. “I am not!”
“You’re a highschool student, of course you are,” Kacchan returns, half laughing. “I remember being a teenage boy. Went through a box of tissues a week.”
Izuku slaps his hands over his cheeks and tries to hide his face between his knees so it doesn’t implode. Thinking about Kacchan’s teenage masturbatory habits is doing absolutely nothing for his crush though. Or his libido, for that matter.
“Aw c’mon, we’re both guys aren’t we? What’re you thinking about?” Kacchan cajoles, reaching across to jostle Izuku’s leg none too gently. His touch practically burns through the fabric of Izuku’s pants.
Scrambling for something to say, Izuku latches onto the only plausible explanation he can come up with short notice. “It’s not! Um. It’s not what you think,” he mumbles, unfolding himself from his defensive curl. It knocks Kacchan’s hand off his leg, which is a tragedy, but he can think clearer without the man touching him. “I just. I have a date this weekend?”
The car swerves so suddenly that Izuku slams into the door with a confused oomph.
“Shit, sorry,” Kacchan mutters, and the teasing, amused expression on his face is nowhere to be found. Instead he’s practically glaring at the road in front of them, both hands on the wheel, fingers going white with pressure.
Izuku licks his lips, nervous for a new reason now. What did he say? Did he make Kacchan mad somehow?
“So. A date?” Kacchan says, and it sounds kind of like he’s aiming for a light tone, but his voice just comes out tight and unnatural.
“Yeah,” Izuku says slowly, watching the older man carefully for his reaction. “A classmate, Todoroki, asked me out.”
“You like him?” Kacchan’s eyes don’t deviate from the road for even a second, not even when they roll up to a red light.
“I guess. I’ve never really thought about him that way. But it’d be rude to say no, right?”
At that, Kacchan’s shoulders seem to loosen a little, and he glances at Izuku out of the corner of his eye. “No. If you don’t wanna go then don’t, idiot.”
“I-it’s not like he’s forcing me!” Izuku is quick to reassure, settling a little now that Kacchan doesn’t seem quite so…what even was that? Anger? Izuku has no clue, and he’s always figured himself pretty good at reading Kacchan.
The car pulls up outside Izuku’s house, and Kacchan doesn’t even bother to put it into park, instead sitting with his foot on the brake. His eyes glance towards Izuku for only a moment, and then he’s jerking his head towards the house. “Get out, kid, I got places to be.”
Izuku swallows hard, lingering a moment. There’s still tension in the air he doesn’t understand, a cant to Kacchan’s jaw that doesn’t make sense. But he’s too much of a coward to push, at least right now, so he ducks his head and does as he’s told. He doesn’t even make it to the front door before he hears the car pull away from the curb with a squeal of rubber on asphalt.
Usually Kacchan at least waits to see if Izuku makes it inside alright.
oOo
Izuku and Todorki meet up at a diner only a few blocks from the school. It’s quiet for the weekend, but well-lit and not too expensive. They pick a booth with cracking leather seats that squeak a little when Izuku rocks from side to side nervously. He can’t help it though! This is his first date and he’s not entirely sure what he’s supposed to be doing right now.
Considering how long he’s been in love with Kacchan, Izuku’s never really thought about what a normal first date might be like. His fantasies always involved blond hair and dim lights and considerably less clothing. If there was a table involved at all, Izuku was usually laying on it.
Ooookay, get your thoughts out of the gutter!
Izuku clears his throat and shifts his weight again, glancing over the top of his comically large menu to find Todoroki already looking at him. Flushing, Izuku jerks his gaze back down. It floats up before he can stop himself though, and he meets Todoroki’s eyes once more. This time a small smile tilts the other boy’s mouth up, a quiet amusement that makes Izuku laugh a little at himself. Yeah, he’s being pretty ridiculous.
“Nervous?” Todoroki asks, laying his menu flat on the table.
“Yeah,” Izuku admits quietly, still hiding behind his. “I’ve never been on a date before.”
“Me neither,” is the quiet response, and then Todoroki turns his attention elsewhere. It gives Izuku much needed time to breathe out and slump back into his seat.
Todoroki is pretty attractive, Izuku can admit. But he’d meant what he’d told Kacchan; up until Todoroki had asked him out, Izuku had never thought of the other boy as anything more than a classmate. He’s quiet, smart, and has a good sense of humor if you bother to stop and listen for it. But that’s it.
Could Izuku date him and be happy? It’s not like it has to be forever or anything, they’re only fifteen. But Izuku doesn’t want to date someone he doesn’t like at least a little. And he’s not sure he likes Todoroki like that.
Well, that’s the point of the date, isn’t it? To see if they’ll fit together?
A waitress comes by, startling Izuku out of his thoughts. Thankfully Todoroki orders first, giving Izuku just enough time to actually read something on the menu and pick it at random. She wanders away once they’re done, and the table is thrown back into awkward silence.
Without a menu to hide behind, Izuku continues his rocking and picks up his straw wrapper to ball up and tear into pieces.
“Soooooo,” Izuku says, eyes flickering up to Todoroki then back down to his hands. How the hell does anyone do this?
But then Todoroki leans his elbows on the table and asks a question about school and something unknots between Izuku’s shoulder blades. Because he knows Todoroki. They go to school together and talk at lunch nearly every day. They’re friends. The conversation flows easily after that, even after they get their food, and Izuku stops his nervous rocking back and forth.
It’s not until he’s halfway through his plate that Izuku looks up and sees him.
Kacchan.
He’s in a corner booth facing Izuku and his red eyes are narrowed, intense. Even from a distance Izuku can tell his jaw is set and that the man is pissed.
What the hell is Kacchan even doing here? A flutter of panic and something else thrums through Izuku. It’s so strong, so sudden, that it puts into stark reality exactly what Izuku’s been feeling for the past hour and half he’s been sitting at this table: nothing. Nothing at all.
Yeah Todoroki is nice, but Izuku feels nothing for him outside of friendship. Seeing Kacchan across the room and having his heart try to jump its way out of his ribs in response makes it easy enough to see what love actually feels like.
“Are you okay?” Todoroki asks, and Izuku startles so badly that his knees slam into the underside of the table.
“Fine,” he winces, forcing himself to tear his gaze away from Kacchan. There’s no way he can mention the man to Todoroki. What would he even say; ‘Sorry, the adult man I’ve been in love with since I was five is sitting across the room and glaring at me and I don’t know why but it’s making my heart race’? Absolutely not. “Totally fine. Just, uh, I need to go to the restroom?” It comes out as a question, but Izuku is already sliding out of the booth.
If Todoroki notices anything odd with the way Izuku’s acting, which, let’s be real, a blind man would notice, he mercifully doesn’t point it out.
Izuku hurries across the restaurant and does his best not to look anywhere near where Kacchan is sitting. Still, he can practically feel that the blond is getting up and following him into the restroom. In fact, Izuku’s barely opened the door before he’s being shoved against a wall and the door is closing and locking behind him.
“Kacchan?” Izuku asks, scared. One moment his cheek is pressed against cool tile, and the next he’s being turned around and shoved backwards so hard that his head cracks against the wall. “Kacchan!”
The man in front of Izuku is nearly unidentifiable. Izuku’s never seen him look so angry before. There’s practically smoke billowing out of his nose as he breathes out, long and harsh. His mouth twists, teeth flashing predator-like in a snarl of rage. Their height difference makes him tower over Izuku, so close that Izuku’s neck is craned up to see him.
“What. The. Fuck?” Kacchan snaps.
There are so many emotions running through Izuku that he can’t settle on just one. Fear? Absolutely. Confusion? Probably more than anything else. Lust? Fuck, he’s half-hard just from having Kacchan’s weight pushing him into the wall.
“Um?” Izuku says, squirming under that weight. “I-I don’t…Kacchan, what’s going on?” The bathroom light is being blocked out by Kacchan’s big frame, and the shadows just serve to make Izuku all the more nervous. It makes it feel like this is something clandestine. Something dangerous.
“What’s going on?” The arm across Izuku’s throat loosens as Kacchan leans away from him. “What’s going on here is that you’re supposed to be in love with me. What the fuck do you think you’re doing going on a date with someone else?”
A new emotional cocktail joins the party as horror and embarrassment wash over Izuku. “I’m not in lo- I mean, I don’t-!” he splutters, trying to get the words out but unable to make his tongue function properly.
Kacchan just snorts. “Fucking please. You’ve been in love with me for years now,” he says dismissively. “I’ve known since day one. You’re not exactly subtle, nerd.”
Izuku’s jaw snaps closed with an audible clack. He can physically feel the blood rushing to his face, skin going hot with mortification. Something about his expression of fear amuses Kacchan because the blond laughs, his shoulders loosening a little. He still doesn’t let Izuku go but he’s smiling now, and his snarl is nowhere to be found.
“What, you think I didn’t know? Kid, you’re so obvious it hurts.”
“A-am not!”
“Are too. Our mothers used to joke about how they wanted to plan our wedding,” Kacchan teases. “You’re constantly following me around, always looking at me with those stupidly big eyes of yours, hanging off my every word…fuck, Izuku, the last time we went to the pool I caught you literally drooling over me.”
Izuku’s face grows hotter with every word, until he’s squirming anew, only this time it’s because he wants to find a hole to jump in and die because holy fuck. There’s no way he’s been that obvious this entire time right? Both of their parents’ don’t know? Have they all just been laughing about Izuku’s stupid little kid crush this entire time? Was Kacchan…
Tears prickle at the corners of Izuku’s eyes and he turns his face away, trying desperately to get a hold of himself.
“So what?” he says, voice coming out wobbly. “So what if I am? You’re just gonna make fun of me for it now…now that I’m-” in love with someone else? As if. Todoroki is nice and all but Izuku doesn’t even like him like that, much less love, “-trying to date?”
And there’s that dark expression again, Kacchan leaning in close. He’s tall, so much taller than Izuku that he’s leaned over him, boxing him in with more than just the arm across Izuku’s throat. “No. I’m not making fun of you,” Kacchan says, and he doesn’t sound angry but the amusement from before is gone. “I’m reminding you that you should be in love with me. And that I’m not going to fucking let you fall for someone else.”
Something trembles inside Izuku and he can’t help looking up into those red, red eyes, searching. “What?”
“I have waited far too long for you to go off and pick someone else over me,” Kacchan continues, staring Izuku down. “I’ve been so good. So patient. I wanted to wait for you to grow up properly and everything. But if you’re going to go down this dating road and try to leave me behind? Fuck it and fuck you. I’m not gonna risk waiting any goddamn longer.”
One moment Kacchan is looking down at him, looming almost, and the next he’s leaning closer and kissing Izuku. Kissing.
Izuku’s brain short circuits, trying to understand exactly what’s happening.
Kacchan is kissing him. He doesn’t want Izuku to date. He’d been waiting, but now he’s not waiting anymore and-
A hot, wet tongue sweeps into Izuku’s mouth and his thoughts scatter like leaves on the breeze. Suddenly he doesn’t care anymore about what’s happening or why. All that matters is that Kacchan’s lips are hot and slightly chapped and moving against his. Izuku tries to match their rhythm, feeling clumsy and young, but Kacchan just groans and presses in tighter. The arm across Izuku’s throat finally moves, and two huge, hot hands find Izuku’s hips instead, jerking them forward into Kacchan’s body.
When Kacchan pulls back, Izuku is left panting and dazed. He stares up at the blond in amazement, thoughts still swirled and slow and nonsensical.
Kacchan just smirks down at him, licking at his lower lip in a move that momentarily steals all of Izuku’s attention. “You suck at that,” the man says, his voice all low and graveled in a way that makes Izuku shiver. “But I kinda like it. Means I’m your first.”
Izuku squeaks. “Of course you are! I’ve never…never-” he can’t even finish the sentence, it’s too embarrassing. Fifteen years old and he’s never even kissed anyone before today.
“I know you haven’t. I would have killed anyone who even tried it,” Kacchan says and he’s…he’s serious, Izuku can see it in his eyes, in the squareness of his jaw. It makes Izuku swallow hard and maybe freak out a little because who is this man and what did he do with Kacchan?
Except it makes sense, really. It fits perfectly into what he knows about Kacchan, how passionate a man he is, that obsessive streak he gets sometimes that runs just beneath the surface. He may come off as just some asshole -strong and wickedly smart and good at everything he does but an asshole nonetheless- but Izuku knows him better than anyone else. He’s watched Kacchan, studied him really, for years. And Kacchan is possessive at heart.
Apparently, that possessiveness extends to Izuku, and has for a while now. Izuku feels nearly dizzy at the prospect.
“You really mean that?” Izuku asks anyway, reaching up hesitantly to touch Kacchan’s cheek. His skin is hot and Kacchan turns into the touch immediately, until Izuku’s fingers are at his lips and he can nip at the sensitive skin of Izuku’s finger tips.
“You know I do, kid,” Kacchan rumbles. “I-”
A knock on the bathroom door startles them apart. “Izuku? Are you okay? Why’s the door locked?” comes Todoroki’s voice from the other side.
Instantly, Kacchan’s face is screwing up in anger, teeth baring, and Izuku jumps to grab the older man’s arm when Kacchan pulls away.
“I-I’m fine!” Izuku calls, voice wobbling. Kacchan isn’t fighting him but Izuku still has his weight set back in his heels, just in case. As if he’d ever be able to physically stop Kacchan from doing anything. “I just, um, maybe I ate something bad? And I-I don’t feel great so, you should, um probably go? Yeah! You go home and I’ll call my mom and she’ll come pick me up.”
There’s silence from the other side of the door, and without seeing his friend’s face Izuku can’t tell if that’s a good thing or a bad thing. Probably bad, right? Finally he hears a quiet, disbelieving, “Okay. But let me know when you make it home safe.”
Izuku lets out a relieved breath. “Okay!” he calls, then waits a few seconds before carefully letting go of Kacchan’s arm. The blond huffs and shakes the appendage out, cutting his eyes towards Izuku with menace. Izuku would take a step back but there’s no room with him still up against the wall.
“What!? I got rid of him, didn’t I?” Izuku hisses in a near-whisper, unwilling to risk the chance that Todoroki is still waiting by the door. Or anyone else for that matter. This is not a single stall restroom, and the door being locked is super fucking suspicious. Izuku gets the feeling he’s going to have a lot to answer for come Monday.
“You shouldn’t have been here with him anyways,” Kacchan snaps back, not bothering to lower his voice in the slightest.
“Well maybe I wouldn’t have come if you’d told me about-” Izuku makes an abortive hand flapping motion between them, “all of this!”
Kacchan just rolls his eyes and grabs Izuku by the wrist, unlocking the door with his other hand and hauling the teenager after him like a naughty child. “C’mon. We’re going home.”
Luckily there’s nobody waiting for them on the other side of the door, but they do get a few curious looks from the staff when Izuku initially tries to dig his heels in and Kacchan physically drags him across the floor. After that Izuku puts his head down and follows obediently. Kacchan’s grip on him doesn’t loosen.
It’s not like Izuku actually opposes Kacchan taking him home; his date has been ruined anyways, and any hope Izuku had of trying to move on from Kacchan has been completely dashed. He’ll just apologize to Todoroki at school and try to play this whole thing off.
What Izuku doesn’t like is being yanked around like a little kid and the angry set to Kacchan’s jaw that hasn’t left since they were interrupted.
“Can you let go of me?” Izuku says the moment they’re outside.
“That depends, are you going to try to run off with some other guy again?”
“I wasn’t-!”
Again, Todoroki’s voice interrupts them. “Izuku?”
Izuku spins on his heel to find Todoroki staring at them, about to climb into a waiting car. “Um-”
“I thought you said your mom was coming to pick you up?”
Kacchan’s grip on Izuku’s arm finally disappears, but only because he’s going around the side of his own car to get into the driver’s seat. “C’mon,” he snaps at Izuku, ignoring Todoroki entirely except for a brief, unsubtle glare.
“Uh, he’s my uh, neighbor,” Izuku says, looking between the two of them. “He gives me rides?”
Todoroki doesn’t mention the fact that Kacchan clearly came out of the restaurant with Izuku. He just cocks his head to the side and asks, quietly, “Are you okay?”
“He’s fine!” Kacchan snaps, and then gets into the car, slamming the door behind himself. The engine revs a moment later.
“I-I’m fine, really,” Izuku reassures, trying to sound as natural as possible. Todoroki doesn’t look convinced but Kacchan is clearly impatient so Izuku decides that’s a problem to deal with another day. He gets into the car before Kacchan can decide to leave without him.
Unfortunately for him, Kacchan is nothing if not possessive and petty. He rolls the window down before he peels out of the parking lot, shouting a last, “By the way, he’s off the market, asshole! Ask him out and again and see what fucking happens!”
Izuku’s cheeks heat and he groans, sinking into his seat. “You’re a dick, you know that? He’s going to have so many questions when we go back to school.”
Kacchan just smirks and changes lanes, already over the speed limit seconds after hitting the road. “If he knows what’s good for him, he’ll keep them to himself.”
Izuku fidgets where he’s sitting, stealing glances at the man beside him. “Yeah but…you know you could get in trouble, right? Because I’m still a minor?”
“Wow, presumptuous much? Who says I’m going to do anything illegal.”
Izuku’s cheeks flush once more, though at this point he’s not sure he ever stopped blushing since he walked into that bathroom. “Um. I mean, you did just insinuate that we’re, you know, together.”
“So? Tell him we’re not,” Kacchan says dismissively, all arrogance.
Izuku huffs, about to tell Kacchan off because if he actually cared he wouldn’t have said that shit to Todoroki in the first place. But then there’s a big hand on Izuku’s knee, squeezing and sliding up his thigh just high enough to be inappropriate.
“I’m definitely planning on doing some illegal things though,” Kacchan murmurs, his voice that low rumble again that Izuku’s never heard before. His stomach flips and his breath catches. “Many illegal things, if I can help it. Which I can. So you better be ready.”
Is Izuku ready? He likes the hand on his thigh, likes the heat of it, the possessiveness of it. But more? He’s certainly daydreamed enough about what Kacchan is like in bed, but Izuku is fifteen and inexperienced and he’s not entirely sure he knows what he wants.
Well, that’s not completely true. He knows he wants Kacchan. Without any reservations or reserves. So by extension anything Kacchan wants, Izuku wants too, right?
Izuku fits his hand over top of Kacchan’s, marveling at the difference in size between them. He likes it. A lot. Kacchan being so much bigger and stronger and older than him has always featured prominently in his fantasies.
“Okay,” Izuku says, long after the silence has stretched and settled comfortably. “I’m ready.”
Kacchan glances at him, head cocked to the side like he’s analyzing Izuku. But he doesn’t say anything, just squeezes Izuku’s thigh and keeps driving.
The apartment Kacchan rents is downtown and has its own parking garage. It’s a pretty expensive apartment Izuku knows, but he’s never had to deal with money so he’s not sure exactly how expensive or even how much money Kacchan makes. All he knows is that Kacchan is pretty well off, and high up in his company.
Izuku’s only been to the apartment a few times; most of their interactions happen at their childhood homes. But on the few occasions he has been inside, it’s always awed him just a little bit. It’s big and modern and has all these masculine, refined touches that he wouldn’t normally associate with Kacchan, but which make the man seem even more adult than usual. Izuku doesn’t dislike it.
The parking garage is dimly lit and quiet when they get out of the car. The closing of the doors echoes, as does the thump Izuku’s back makes when it hits the car next to them, Kacchan suddenly right there in his space.
Izuku has no idea how Kacchan got around the car so fast, but he’s not sure he cares.
There’s a hand fisted in the front of Izuku’s shirt and a mouth on his, claiming, biting, a tongue slipping between his lips and making him moan shakily. He doesn’t know what to do except grip Kacchan’s arm and hold on for the ride.
When Kacchan finally lets up, Izuku is breathless and the world feels like it’s spinning. The man smirks down at him, wiping at the corner of Izuku’s mouth with a thumb. “You look good like that,” he murmurs. “All dazed and fucked out.”
Izuku flushes with the words and swallows hard. “Aren’t…aren’t there cameras?” he asks, glancing around the garage.
“Dunno,” Kacchan says, flashing him that cocky smirk, and then he’s grabbing Izuku by the waist and hauling him along into the building.
Izuku doesn’t even think about struggling this time, his heart racing in his chest and his nerves on fire. Still, as they’re getting into the elevator he can’t help but comment, “You should be more careful.”
“Why, you scared of getting caught?” Kacchan asks, the doors sliding closed on them. His arm is still around Izuku, keeping their bodies pressed together. The lack of space is doing nothing for Izuku’s ability to think properly.
“No? I mean, yes, but not for me. I just don’t want you to get in trouble.”
“Relax, kid. Just let me handle everything, okay?”
Izuku breathes out softly before leaning into Kacchan’s larger body. He…really can’t do that. He can’t just lay back and let Kacchan deal with all the potential consequences of this relationship. But he can pretend. For right now.
The elevator doors slide open soundlessly and Izuku is ushered down the corridor and into Kacchan’s apartment. It’s exactly as he remembers it, but he’s not given enough time to glance around like he usually does. Instead he’s herded shamelessly into the bedroom. He gives Kacchan a half-hearted swat and a, “Stop pushing me!”
“Fuck off. I’ve been waiting years for this,” Kacchan grumbles in response, ripping Izuku’s shirt over his head with a nearly startling level of violence. Then he shoves Izuku at the bed, making him stumble and fall onto the mattress.
“Y-years?” Izuku asks, picking himself up onto his elbows.
“Yeah, years, idiot,” the man snaps, but he’s unbuckling his belt with hands that are quick with excitement, and the hot look in his eyes is one of expectation. “You’ve been mine nearly since the moment we met. You were so fucking cute and trusting. And now you’re growing up and getting all sexy and mouthy and shit. Fuck, I can’t wait to ruin you.”
Izuku’s mouth goes dry and he sucks in a shaky breath. It’s not that he thinks he’s unattractive necessarily, but the downright hungry way Kacchan is looking at him is not something Izuku ever could have imagined. Nobody looks at him like that. He’s plain. Average. Run of the mill. But Kacchan is crawling across the bed towards him, stalking him like a predator, like Izuku is something he wants to eat. Devour. Like he thinks Izuku is going to be the best thing he’s ever tasted.
In that moment Izuku really and truly believes how much Kacchan says he wants him in a way he hadn’t quite been able to earlier.
Kacchan pauses when he’s hovering over Izuku, his bulk once again blocking out the light above. His chest and biceps flex, his hands curling tight into the fabric on either side of Izuku’s head, throat working as he swallows. When he speaks his voice sounds rough, like it’s being dragged out of him by force. “Say you’re mine, Deku. Izuku.Tell me you want this.”
Izuku doesn’t even have to think about it, not even for a second. “I’m yours,” he says, and he knows he might not understand exactly what it is he’s agreeing to. How could he? As young as he is there’s so much he doesn’t understand, and Kacchan isn’t exactly being forthcoming with what he’s thinking. But regardless, whatever it is Kacchan is offering him, Izuku wants it. Needs it.
Reaching up, Izuku threads his arms around Kacchan’s neck, tangling his fingers in the fine hairs at the nape of the man’s neck. “I want this. I want you, Kacchan. Please.”
Red eyes flutter closed and Kacchan groans. “Fuck,” he mutters, still sounding incredibly ragged. “You don’t even know what you’re agreeing to, kid.”
“Do you care?” Izuku challenges.
“Fuck no.” And Kacchan finally descends, crashing their mouths together in another kiss that scrambles all of Izuku’s thoughts. He’s incoherent in seconds, gripping Kacchan tight against him and unseeing, unfeeling, of anything outside the man. This man that he loves so, so much.
The only clothes they’ve managed to get off is Izuku’s shirt. But Kacchan makes quick work of Izuku’s pants and underwear too, almost without Izuku noticing at all. But it’s hard to miss the drag of rough fabric over his cock and damn when did he even get hard? Maybe he’s been hard this entire time, since Kacchan followed him into that bathroom. Or maybe when he touched Izuku’s thigh in the car. When he pushed Izuku up against a stranger’s car. The possibilities are endless.
Izuku shivers when he’s completely bare and Kacchan pulls back, clearly appraising the high-schooler in his bed. Again Izuku is struck with that feeling of being wanted. Being desirable. Kacchan clearly likes what he sees judging by his hooded eyes and the way he licks his lips. It makes Izuku want to stretch and maybe show off a little, even though he’s never thought of himself as being even the slightest bit sexy.
“God, you don’t know what you do to me,” Kacchan says. He shifts his weight to one hand and drags the other down Izuku’s chest to his waist. His fingers are calloused and rough against Izuku’s comparatively smoother skin but the sensation is anything but unpleasant.
“You too,” Izuku says, those red eyes making him feel bold, feel coveted. “I’ve been thinking about you for years,” he admits, biting his lower lip.
Immediately Kacchan’s eyes are on Izuku’s face, and those thin lips are pulling into a familiar smirk. “Oh yeah? You beat off thinking about me, baby?”
Izuku sucks in a sharp breath at the pet name, unprepared for how intimate and warm it feels. His cock twitches against his thigh and he has to swallow hard before he can answer the question. “Y-yes. All the time.”
“Tell me about it,” Kacchan demands, and reaches down to palm Izuku’s cock. Izuku immediately moans, hips jerking up. He’s never been touched by someone else and the pleasure of an unfamiliar hand, of Kacchan’s hand nearly has him coming undone right then and there. But Kacchan sits up and uses his other hand to hold Izuku’s hips down, pins him to the mattress with an ease that’s incredibly hot. The hand on Izuku’s cock is slow and teasing and no longer touches with enough pressure to actually make Izuku come.
“Tell me,” Kacchan demands again, growling the words. “I want to hear what you think about when you get off. What’s that filthy little mind of yours come up with, huh? You think about my mouth, my body, my cock?”
“Yes,” Izuku gasps, trying and failing to press up into the faint pressure of the hand moving on his dick. There’s drool collecting at the corners of his mouth, he can feel it, but he can’t coordinate his body enough to swallow it properly. All of his attention is focused on Kacchan and those red eyes, that demanding, cocky look the man is pinning Izuku with.
“I think about…about,” there’s a fear in admitting his fantasies, a subject he’s never discussed with anyone before, but Kacchan is so steady, so demanding in his stare that Izuku can’t stop the words from bubbling up out of him. “I think about you t-touching me, how big your hands are and how much you probably know. About…about sex. And how you’d teach me.”
“Yeah? You want me to show you good I can make you feel, baby?”
“Please!”
“What else?” The hand on Izuku’s cock still hasn’t picked up it’s pace and Izuku whimpers, knowing Kacchan won’t stop tormenting him until he gets what he wants.
“I think about how you’d teach me how to make you feel good too,” Izuku admits. He’s not sure when he threw his arms over his head, but he’s gripping the sheets tight between his fists, twisting and turning the fabric to try and anchor himself. “You…you’re so rough, and mean. You’d tell me how bad I am at it until I finally learned how to do it right.”
That earns him a reaction, a growling noise from Kacchan and more pressure on Izuku’s cock that makes him cry out in pleasure.
“Keep going,” Kacchan orders. “You want me to call you a dumb little bitch? A useless kid who doesn’t know how to handle an adult cock properly?”
Izuku whines, thrashing gently in the combined bindings of Kacchan’s weight on his hips and his own self-made grip on the sheets. “Yes!” he cries, earning himself even more pressure.
“Good, I want that too. Now come.”
Izuku does, so hard that his vision whites out and his entire body shudders uncontrollably. When he comes back to himself his chest is heaving and covered in sweat and Kacchan is sitting over him, completely clothed and unbothered still. He licks some of Izuku’s cum off his thumb and smirks down at him.
“There you are,” he says. “I was worried you’d passed out on me. Can’t believe you came so early when there’s so much I still want to do to you.”
“Don’t be mean.”
Kacchan’s smirk sharpens. “I haven’t even started being mean yet, kid.”
Izuku swallows hard and manages to gather enough coordination to push himself up onto his elbows. He reaches out with one trembling hand to fist the fabric of Kacchan’s first, tugging on it. “Will you take these off? I feel weird being the only one naked.”
That makes Kacchan snort, but he pulls the shirt up and over his head with ease, tossing it somewhere off the bed. The ripple of his flesh in the artificial light makes Izuku’s mouth water. He’s all corded muscle and pale skin, the bulging of his biceps and pecs practically obscene, and Izuku falls back onto the mattress with a gentle oomph.
Kacchan laughs at him, clearly amused. “Like what you see?”
Izuku nods and doesn’t resist when Kacchan grabs one of his hands and places it on the man’s abs. “Go on, don’t be shy. You can’t be the only one here who gets to feel good.”
So Izuku does as he’s told, using both hands to gingerly touch Katsuki’s chest and stomach and arms. He doesn't really know what he’s doing, but it feels good to touch regardless. His fingers tremble a little when he reaches the waistband of Kacchan’s jeans, but Kacchan just reaches between them to flick the button open and shove them down.
And oh god. That’s his dick. It takes a moment for Kacchan to work it out of his underwear because it’s just so big. Izuku had no idea they could get that big. Like, logically he probably did, but he’s only ever seen his classmates’ and he doesn’t really watch that much porn, preferring his imagination, and Kacchan is just huge. Bigger than Izuku ever could have imagined.
“Are you just gonna sit there and stare, or am I going to get to come today?” Kacchan asks dryly, and Izuku snaps his jaw shut from where it fell open.
“S-sorry,” he mumbles, and grabs Kacchan’s cock. It’s hot and feels just as big as it looks when Izuku tries to give it a tentative stroke. His fingers don’t even reach all the way around.
Kacchan gives a low sound of pleasure and god, Izuku’s going to be thinking about that for days. It’s almost unbearably hot, knowing it was him who made Kacchan sound like that, that Izuku is the one bringing this man he loves so much pleasure.
“Hey, fucking focus, nerd,” Kacchan snaps suddenly, and Izuku jerks in surprise.
“Oh, uh, sorry,” he mumbles, flushing a little.
Kacchan raises an eyebrow at him. “What the fuck could you possibly be thinking about right now? You’ve literally got my dick in your hand, that not good enough for you?” There’s a hint of threat to the words, like earlier when Kacchan had been asking if Izuku really is more interested in Todoroki than him. Izuku is starting to sense a pattern here, that ugly, mean streak of Kacchan’s, the one more dangerous than his normal asshole-ishness, rearing it’s head when he thinks Izuku isn’t focused completely on him.
“N-nothing!” Izuku squeaks. “Just, it’s kind of crazy to think I’m getting to make you feel good.”
Kacchan’s snorts. “That’s your problem, always thinking too much. Just fucking be in the moment for once in your life.” He leans back, shoving at Izuku’s wrist to get free of his hand, but only so he can pull his pants and underwear off entirely. When he crawls back over Izuku, completely naked now and making Izuku’s breath stutter to a complete stop, his eyes are blazing and his jaw is set.
“And if I think even for a second that you’re not thinking about me? You’re gonna fucking regret it, kid,” he warns, all rough and low. “I’m the only one who gets to do this to you, and I better be the only fucking thing on your mind while it’s happening. I make you feel good, I make you come.” His hand drags down Izuku’s chest and stomach to his limp dick and Izuku flinches as rough fingers close around flesh that’s still sensitive.
“Nobody else is going to make you feel as good I do,” Kacchan warns, squeezing just enough to make Izuku whine and try to twist away from the touch. The man is too big though, too all encompassing, and there’s nowhere for him to go.
“And if you want to try and test that theory? I’ll kill whoever you try to fuck.” There’s no hesitance to the words, only cold, hard certainty. Izuku believes him one hundred percent. And maybe that and the over-stimulating, demanding hand on his dick should worry him. They’re probably giant red flags. But Izuku doesn’t care, feels flushed all over that Kacchan is so damn covetous of him. Izuku feels loved and desired in an unfamiliar and addicting way.
“Never,” he promises, reaching up to wrap his arms around Kacchan’s throat, even as his voice comes out slightly pained and his hips try to roll out of Kacchan’s grasp. His dick is starting to respond despite the painful stimulation though, thickening up in Kacchan’s hand. “I’d never even dream of it. You’re all I want.”
Kacchan smiles down at him, all predator. “Good. You’re mine, don’t you go fucking forgetting it. Now stop squirming, I want to fuck you and it’ll be a lot less painful for you if you’re hard.”
Izuku does whine at that, and his dick finally gets with the rest of the program and hardens up the rest of the way. That seems to please Kacchan who finally lets go with a smirk, and reaches over to open the nightstand drawer. He rummages for a moment before coming up with a bottle of lube and a condom. The latter he hesitates over, flicking his gaze from the silver wrapper to the Izuku then back. Then he throws it back into the drawer and closes it with more force than necessary.
“No condom,” he says, sitting back on his heels between Izuku’s spread and willing thighs. “I want to feel you. Want to come inside that tight little virgin ass.”
Izuku swallows hard, dick twitching. Every lesson he’s ever had about safe sex is screaming in the back of his mind, but he shuts it down. Kacchan wouldn’t risk Izuku’s health, so there’s nothing to worry about. Plus the idea of feeling Kacchan raw, of having that connection. It’s hot, and Izuku wants it. “Okay.”
“I wasn’t asking,” Kacchan says imperiously, and coats his fingers in lube. The first touch on Izuku’s perineum, trailing down to his hole, makes him jump. Kacchan just smirks. “You telling me you never done this to yourself?”
“No, I have,” Izuku admits, flushing a little. “I just…you’re the first to um, do it to me.”
“Of course I am,” Kacchan says smugly, and repositions them so that one of Izuku’s legs is thrown over his shoulder, opening Izuku up and giving Kacchan more room to work with. The first finger slides in at the same moment Kacchan turns his head and bites at Izuku’s calf. Izuku isn’t sure which sensation to pay attention to first and he jerks, a sound of confusion spilling from his mouth. The finger doesn’t hurt though, and neither does the bite.
“You fuck yourself on your fingers thinking about me?” Kacchan asks, letting go of his mouthful of flesh. There’s a faint red mark from his teeth on Izuku’s skin.
“Um. Yeah.”
“Of course you do. You’re fifteen and horny as fuck,” Kacchan teases. “Bet you come all over yourself thinking about me fucking you into the mattress of your childhood bed.”
Izuku isn’t sure his face can get any redder and his fingers twist in the sheets anew. “So what if I do?” he squeaks.
“It’s not a bad thing,” Kacchan says, kissing the bite mark and adding a second finger. Before it hadn’t felt like much, just a warm, wet intrusion, a little weird but not unfamiliar. Now Izuku is starting to feel the stretch and burn.
“I jack off thinking about you too,” the man continues, stealing Izuku’s attention back. “Think about ruining you. About fucking you till you cry. About taking you over my knee and spanking you until you come.”
Spanking him!? Now there’s a fantasy Izuku’s never considered before, but he can’t say he’s completely uninterested. The two fingers in him find his prostate and Izuku moans, back arching, and the sudden pleasure has him imagining. Lying across Kacchan’s lap like a naughty child, his hand finding Izuku’s ass over and over again until it’s hot and red and Izuku is grinding against his thigh trying to find release.
Izuku comes all over his stomach without warning, breath hitching, jaw dropping open on another moan.
Between his thighs Kacchan pauses, both eyebrows jumping up in surprise. “Really? That did it for you?”
Izuku’s breath is too ragged for him to do much more than swallow and nod. It gets him a laugh from Kacchan, something a little cruel, before those fingers find his prostate once more and press. Izuku cries out, too sensitive, trying to writhe away from the touch, but Kacchan holds his hips down and keeps at it.
“God, you’re secretly a little slut, huh?” he says, talking louder to make sure Izuku hears him over his own moans and cries. “I knew you would be. C’mon, you’re fucking fifteen, you can come again. Give it to me.” The last words are growled, a command, and with a sob Izuku does. His cock spurts out a pathetic little dribble of cum to join the pool on his heaving stomach and Izuku’s eyes fill with tears in response.
Thankfully Kacchan pulls his fingers out and gives Izuku a moment of reprise. His smile is still cruel though, his voice rough when he says, “Good boy. Fuck, I knew you’d be a crier.”
Izuku sniffles and tries to catch his breath. “I knew you’d be mean,” he shoots back.
Kacchan just laughs at him and roughly tilts Izuku’s hips up, taking his own cock in hand to line them up. For a moment Izuku thinks about protesting; he’s not sure he can take much more. But he asked for this, agreed to it when Kacchan said he wanted to ruin him. So he only cries out and grabs the sheets underneath him instead of protesting when Kacchan pushes into him, too fast, too much at once. It burns, Kacchan so fucking big that Izuku’s body can barely process exactly how full he is.
“God,” Kacchan groans, eyes fluttering. His fingers are too tight on Izuku’s hips, hot like brands. “Virgin pussy is the best. Can’t believe you’re letting me fuck you like this, letting me take your virginity, be the first person in this tight little ass.”
The stretch is fading bit by bit, but Izuku’s breath is still hitching, eyes still watering. “Of course it’s you,” he shoots back, making Kacchan’s eyes snap open to focus on him. “Who else would I let do this, you asshole. I love you.”
For a moment Kacchan softens and his grip loosens. He even reaches up to wipe some of the tears off Izuku’s face before they can dry itchy with salt. “I love you too, kid.” But it doesn’t last. His eyes hood, his mouth pulling up in something not quite a snarl, not quite a smile. “And that’s why I’m going to ruin you for anyone else. You’ll never want another cock except mine for the rest of your fucking life.”
Izuku wants to tell him that he’s already ruined, has been since he was ten and very first figuring out what his dick was for. But if Kacchan needs this, needs to push Izuku down into the mattress and fuck him in long, unhurried strokes that make Izuku’s spine arch, then he can have it. Especially since it’s starting to feel good, the constant push pull and friction lighting up sensitive nerve endings until Izuku’s reluctant cock once again joins the party. He’s not convinced he can come again, but Kacchan seems determined to make it happen anyways. His dick presses constantly against Izuku’s prostate, battering it over and over again until Izuku is outright sobbing from the overstimulated pleasure.
Kacchan makes this soft cooing noise, never once stopping the flexing of his hips. “You look so good when you cry.”
“Jerk,” Izuku accuses. But he’s learning the rhythm of Kacchan’s body, learning how to move his hips to meet the man thrust for thrust and guide his cock where it feels best. And god does it feel good. Izuku had no idea sex would be this amazing, like his entire body is being lit up from inside with electricity. Masturbating alone is never going to satisfy him again.
He must have said that last part out loud because Kacchan laughs lowly. “That’s the idea, kid. You’re gonna be desperate for me from now on, because I’m the only one who can make you feel this good.”
“Only one,” Izuku echos, reaching up to dig his nails into Kacchan’s thick biceps, the muscles sliding under his fingers as the man moves.
“Mm, that’s right. You’re mine now.”
It feels like hours that Kacchan fucks him, inexorable and constant. He moves them a few times, introducing Izuku to a litany of positions, each one bringing with it its own pleasures. He finds himself especially fond of the one with them on their sides, Izuku’s back pressed to Kacchan’s huge, sweaty chest, Izuku’s leg lifted up and back so Kacchan can roll against him, never really pulling his cock out. They’re able to kiss like that, if Izuku arches his neck back, and that’s how he comes for the fourth time that night. Trembling and still crying, every muscle in his body feeling wound too tight. His orgasm rolls through him almost angrily and then he collapses, unable to hold his weight up anymore.
Kacchan groans against the back of his neck, his hips shuddering where they’re still pressed against Izuku’s ass. Distantly Izuku can feel the warm wetness inside him, can feel the minute tremble of Kacchan’s body, the pulsing of his cock as he stakes his claim. But Izuku’s eyelids are half-shut and he’s exhausted after all he’s been put through. He’s not awake to even be able to wince when Kacchan pulls out.
oOo
It feels like just minutes later that Izuku opens his eyes, but the bedroom is dark, no light shining through the window. Kacchan is also gone but there’s the scent of cooking food on the air so Izuku figures he can’t be far.
Izuku goes to sit up and then groans, flopping back down onto the bed. He’s so sore. Is sex always like this? Exhausting and painful? But also…fucking amazing. Yeah, Izuku is sore from head to toe, and he’s pretty sure he’s covered in bruises to boot, but he also wants to roll around in Kacchan’s bed, kicking his feet and giggling like a child. Kacchan loves him. Wants him. And they had sex! And it was amazing! Izuku’s never felt so good in his entire life. If he was ruined for anyone else by Kacchan before today, now it’s double-so. Kacchan may have just been talking in the heat of the moment, but he’s entirely right; Izuku will never be able to be with anyone else after this.
“Hey, nerd!” the blond’s voice filters from the kitchen, startling Izuku out of his thoughts. “I can hear you overthinking in there! Get up and come eat dinner.”
“Okay!” Izuku calls back, and sits up much more slowly this time. His body still protests but not nearly as bad as before. Sure enough, when he glances down at himself he can see a smattering of purple bruises on his hips, thighs, and chest. They make him flush with warmth.
Izuku’s clothes are nowhere to be found so he rifles through Kacchan’s dresser until he comes up with a pair of boxers and a shirt that’s a little too big for him. They’re comfortable and have the added bonus of making Kacchan double take when Izuku comes out wearing them. Those familiar red eyes narrow, gaze darkening in an expression Izuku is now coming to recognize as lust.
“You look good, kid,” the man murmurs, then seems to shake himself off. “C’mere, I didn’t cook just to make the apartment smell good.”
Izuku joins Kacchan in the kitchen, and despite the man’s demands not to let dinner go to waste, he pulls Izuku close the moment he’s within range. Pulling aside the collar of the too-big shirt, Kacchan hums and drops a close-mouthed kiss to Izuku’s freckled, bruised shoulder. “Mmm, I like seeing my marks on you.”
Izuku shivers, arching his neck a little to give the man room to work with. “Um. I like them too.”
Despite the invitation to keep going, Kacchan stands up again and swats Izuku on the ass. “Of course you do. Now go sit down.”
The table’s already been set and behind him, Izuku can hear Kacchan humming a little under his breath as he plates their dinner. Whatever it is, it smells spicy and rich and makes Izuku’s mouth salivate.
When Izuku sits down a whole new ache makes itself known, up from his tailbone and along his spine. But it’s worth it. It’s all worth it. The anxiety of this kind of relationship, the relationship Izuku will have to mend at school, the secrecy, the lying he’ll inevitably have to do. Because Kacchan is smiling at him and making him dinner and when he sits down he puts his hand on Izuku’s thigh and squeezes.
And it’s good.
