Katsuki had always hated Todoroki Shoto.
Ever since he had first laid eyes on the prodigy child, he had decided that Todoroki was someone he should keep an eye on. A rival, someone who could ruin his plans of becoming the number one hero if he wasn’t careful.
Even now, in their final year at U.A, Todoroki is still Katsuki’s only hurdle. He’s the only one, in Katsuki’s eyes anyway, who is worth worrying about. The dual haired boy had everything, a flashy quirk, an influential father, a pretty face and good grades. It’s not that Katsuki felt inferior to him or anything, he knows that he has an amazing quirk himself, that he’s strong too and just as smart, that he didn’t need to piggyback off his dad’s career to get into U.A, (He knows that Todoroki would’ve passed the entrance exam with ease if he didn’t get to skip it, but that’s not the point.) he’s just very aware that the two of them, in terms of pro hero potential, are pretty evenly matched.
He really, really hates Todoroki.
So why can't he stay the fuck away from him? It's like Katsuki wants to make his own life harder, he could’ve just gone straight to his room to sulk after the other boy had beaten him by one mark in the English test they had sat last week; but no. He obviously had chosen to antagonise Todoroki all week, harassing him for a fight until the other boy had finally given in and said that they could spar on the weekend. that’s how he had found himself in the worst position imaginable, pinned beneath the very boy he hated in the middle of U. A’s practise field. Todoroki’s front pressed against his back, pinning his arms to the floor.
At first, it was only bad because that meant he was losing to the asshole. Katsuki could deal with that; it was a fairly regular occurrence. Todoroki had grown taller, much taller than Katsuki, he was broader, he weighed more, and he obviously knew how to fight. So, he did tend to win more often than not when the two of them fought without the use of their quirks.
Katsuki had attempted to move, trying to gain the upper hand and flip himself around to regain control, causing the taller boy to press into him harder. Todoroki was practically breathing down his neck, his crotch pressing against the cleft of Katsuki’s ass, when he realises how royally he fucked up. His body had betrayed him, and Katsuki is suddenly aware that choosing to go commando in a fit of rage when he couldn't find any clean underwear this morning was a terrible idea, because he is wet. Like, seriously wet. He's not entirely sure his thin gym shorts will be able to do much against the waterfall that has occurred within them.
His mind scrambles for excuses. He must have gotten his period for the first time since he started testosterone, and if not, some other biological phenomena must have occurred, because he definitely does not like Todoroki like that. Infact, he hates him!
And yet... he can't stop thinking about how close Todoroki is to him, his dick only a few inches away from his hole. How all he would have to do is pull Katsuki's tiny shorts to the side to enter his drooling pussy, fuck him right on the field behind their school, where anyone could walk out and catch them. He’s supposed to despise Todoroki for being better than him, for always making Katsuki second guess his greatness, but that only spurs his stupid brain on. He wonders if Todoroki would fuck him hard, whisper nasty things in his ear about how inferior he is while he takes, takes, takes. Or would he pull him apart slowly, tease him and make Katsuki swallow his pride and beg for his rivals' cock?
And yeah, ok maybe it isn’t his period. Or some weird phenomena. And maybe Katsuki didn't choose to go commando solely because he was annoyed, but that's a completely separate topic and he doesn't want to explore his reasonings for that right now. Katsuki has almost soaked his shorts because he felt Todoroki's soft dick against his ass, sue him. Todoroki presses slightly harder against him, and if he wasn’t so caught up in his horny fantasies and panic over potentially wanting to fuck candy cane, he would wonder if the boy did it on purpose. He presses back subconsciously, and a small whimper escapes him before he thinks to suppress it.
Todoroki moves off Katsuki’s back as if he had been burnt.
“Are you okay?”
Shit shit shit SHIT.
He turns to look at Todoroki, and thankfully, he finds a look of what he thinks may be genuine concern. He doesn’t look disgusted at least, so Katsuki hopes the other boy is as oblivious as everyone says he is and doesn’t know what a horny whimper sounds like.
“Yeah, just... uh, fucking hurt my shoulder.” Katsuki manages to spit out. He can feel the heat of a blush radiating off his face, so he runs off back to the dorms before Todoroki gets to say anything.
Once in the sanctity of his own room, Katsuki doesn’t give himself a second to think about what just happened. He doesn’t even make it to his bed, he rips his shorts off and slides down to the floor with his back against the door, sinking two fingers into himself. He imagines Todoroki being the one pushing his fingers into him, Katsuki’s are too short, too rough, he can't get them where he needs them. Todoroki’s would surely be long and smooth, he would hold Katsuki's hips down with one hand while the fingers on his other find his g-spot with ease, rubbing circles around it before relentlessly pistoning his fingers in and out, hitting it dead on with every thrust. Katsuki cums hard at the thought, and it’s the quickest he's ever finished in his life.
It takes him a minute to steady his breathing as he comes down from his high, and an embarrassingly long time to finally pull his pants up and drag himself to the communal showers to clean up. He pulls himself on jellified legs into a stall, turning the water on cold and blasting himself in the face to snap himself out of his haze. When his brain finally turns back on, he's stunned. What the fuck just happened?
Two hours ago, he was ecstatic over the thought of getting to punch Todoroki in his stupid face. Now, he apparently prefers to think about the asshole finger banging him instead. What the hell.
Katsuki has never seriously thought about doing something like that with anyone before. The thought would usually disgust him, the idea of someone else seeing him so intimately. But for some reason, at that moment, all he had wanted to do was lay himself bare for Todoroki to take. It must be some wild combination of teenage hormones, and half and half getting so close to him, that caused such a catastrophic thing to occur, he thinks. Because there is no way in hell he has any sort of feelings for Todoroki of all people. He doesn’t have feelings for anyone! Katsuki doesn’t have time for that shit! And even if he did, icy hot is the last person he would choose to do those things with.
Sure, he's attractive, even Katsuki can admit that. Todoroki is the tall brooding serious type of guy that girls fawn over. And sure, maybe if Katsuki did have any interest in anyone, that’s probably what he would go for too. But Todoroki isn't actually brooding and mysterious, he's just fucking insanely weird and has a boat load of trauma that makes him quiet and have no facial expressions. And Katsuki doesn’t have any interest in anyone anyway, so it doesn’t even matter!
But still, he is so fucking embarrassed he just wants to die. Even if it is just teenage hormones, he had still got himself insanely worked up in front of Todoroki. He had let out a horny whimper in front of Todoroki! Because of Todoroki! And then he had run off to his room to masturbate over him. His life has got to be a fucking joke. He takes out his frustrations on the shampoo bottle currently in his hand, throwing it against the shower wall and letting out a loud groan of frustration.
“Bakugo?”
Katsuki jumps out of his fucking skin, the voice belonging to the very person he was just agonising over masturbating to; he was so lost in thought that he hadn’t even heard anyone walk into the showers. He looks down to see Todoroki’s feet through the gap of the stall door.
“What the fuck icy hot! You stalking me or something?” he snaps and starts gathering his things, turning the shower off. It is time to fucking go.
“No... I'm here to shower.”
“Well, I was just fucking leaving! So, get on with it!”
Todoroki made no move to get on with his shower, standing stationary outside of the stall Katsuki currently occupied. The shorter boy felt himself begin to sweat, his gut coiling in an unfamiliar way. He couldn’t walk out naked in front of Todoroki, and he had stupidly left his clothes outside of the shower, thinking that no one would come in here in the evening. He had no idea if the other boy knew that he was dickless, he certainly hadn’t told him, though he presumed the nerd may have. but even if he did know, he still wouldn’t be parading that fact around in front of him. (Only in his sexual fantasies, apparently.) He needed to get out of here now before he embarrassed himself again, but Todoroki showed no intention of moving.
“Well? Fucking go get in a shower so I can leave! I'm naked you know!”
“I like to use this shower stall, though.”
God, Todoroki always had to be difficult, was always making Katsuki’s life harder.
“God damn it, fine! Just fucking... throw me over my hoodie then!”
Todoroki made a confused noise, but said no further as he, presumably, looked around for Katsuki’s hoodie. The latter breathed a sigh of relief, Todoroki apparently not one to argue that nakedness between men is nothing to be ashamed of. He had previously had that problem with Kirishima, and it hadn't been pretty. The feet appeared at the bottom of the stall door again, and Katsuki’s hoodie landed squarely on his face when Todoroki threw it over.
“Asshole!”
Katsuki quickly shrugged the hoodie on. The feeling of his wet skin against dry clothes disgusted him, but at least it was one of his oversized ones he likes to lounge in. It came to a stop below his upper thigh, meaning he didn’t have to awkwardly hold it down as he walked past Todoroki. He shuffled out of the stall only to be met with his classmate’s chest, because obviously the asshole lacked the common sense to move himself out of the way.
“You’re still soaking wet. You should’ve asked for a towel instead of a hoodie.”
Katsuki feels the beginnings of a migraine begin. It’s like Todoroki is on a mission to piss him off. He’s so monotonous, completely lacks common sense and social etiquette, and he just says whatever comes to mind no matter who he’s talking to. Another thing he gets from having a famous dad, Katsuki supposes, the idiot has never had to learn any of this what not to do or say social bullshit because he can do whatever he wants, because no one is going to tell a pro hero’s child that they are socially inept.
“You are so socially inept.” No one except for Katsuki, of course.
He barges past the taller boy to a bench on the other side of the room where he left all his belongings, including his towel. As he turns back around, furiously towel drying his hair, he’s met with a sight every girl in U.A would be drooling over. Todoroki is totally naked, except for the towel he's holding loosely around his waist. He’s seen him shirtless before, briefly, but this feels different. This time, Katsuki notices the boy is lean, his muscular form defined but not overly so. He notices a few freckles here and there, his protruding hip bones, his V line, his happy trail, which he now knows is split half white and half red just like his hair. Katsuki notices a lot. He feels his face and ears explode into a furious blush as he realises, he has been staring for far too long.
He tears his eyes away and attempts to pull his joggers over his legs as quickly as he can without flashing the other boy, foregoing underwear in favour of speed (with no ulterior motive unbeknownst to even himself this time),stumbling as he does so before turning around to swiftly pack his bag and get the hell out of there. He freezes when he feels Todoroki’s presence behind him
“What's the rush?” The taller boy asks, looming into Katsuki’s space. How is he supposed to function when Todoroki keeps pulling this shit on him? He’s beginning to suspect that the other boy knows exactly what he’s doing, is purposely trying to rile Katsuki up, because there is no way he thinks this is normal. He doesn’t see him running round pushing himself into Deku’s personal space! Insisting on using the shower stall Katsuki was occupying, standing in his way, getting all up in his business. Yeah, the asshole knows what he’s doing alright, he's doing it on purpose! The hands settling low on Katsuki’s hips confirms it.
“What the fuck are you doing?” Katsuki hates how breathy his voice sounds, and once again, he is cursing his body for being a traitor and responding to Todoroki’s touches as he leans into him, his ass moving back towards the other boy's crotch.
“You’ve been acting a bit strange, Bakugo. Is it because you want me to do this?” Todoroki slides his hand down slowly, from Katsuki’s hip to his lower stomach, trailing down to caress the small whisps of hair below his belly button, and the shorter boy can't help the breath of arousal and surprise that gets punched out of him at the contact.
“I’ll take that as a yes?”
This is bad, he knows it, and it will probably lead to a very awkward conversation if they go any further, because Todoroki will realise that he doesn’t have a dick, and he will be very confused. But Katsuki can't think much about that right now, he can't think much of anything. Todoroki’s hand skims higher, every touch sending zaps of pleasure that go straight to Katsuki’s clit.
it's Todoroki’s turn to be surprised as his fingers brush against the cool metal occupying Katsuki’s belly button. The shorter boy hears a sharp intake of breath before he’s swiftly spun around, pushed down to sit on the bench against the wall as Todoroki drops to his knees in front of him, pushing Katsuki’s leg apart and settling between his thighs.
“A belly button piercing?” Todoroki practically growls, his hand still on Katsuki's hips and with the most emotion Katsuki has ever seen on his face. He looks fucked. Pupils blown wide; a light blush spread over his cheeks. The blonde feels a grin spread across his face, emboldened knowing Todoroki is just as turned on as he is. He arches his back slightly, presenting the piercing to the other boy. Said piercing is nothing special, it's just a silver bar with an orange gem in it, but for some reason it drives Todoroki wild. Katsuki sees the change on his face, his eyes darken, and before he even has chance to mock the other boys apparent piercing fetish, Todoroki is practically ripping his joggers off. They both suck in a breath and pause to look at each other.
“Um...” It's rare that Katsuki doesn’t have anything to say.
He considers pulling his pants up and running away before the other boy gets the chance to get a word in himself, but Todoroki instantly stops that train of thought when he lets out a guttural groan, dragging Katsuki into a half laying position on the bench and promptly burying his face in between his legs. Katsuki almost screams at the contact, he has never had anything but his own fingers inside himself, and now here he is, with class 1A’s resident pretty boy’s tongue fucking into him. It hadn't even been half an hour since he had fingered himself to the thought of Todoroki, and now he had his tongue gliding through his over sensitive pussy. One hand flings to the head of red and white hair settled between his thighs, the other clamping over his mouth to stop his loud cries.
Todoroki licks a stripe from Katsuki’s hole to his enlarged clit, laving his tongue over the sensitive nub. He takes it into his mouth and sucks, having to grip the smaller boys' ankles to stop him from kicking out and dislodging him. He pushes Katsuki’s legs up, sliding his hands from his ankles to the back of his knees, effectively folding him in half and giving him access to easily slip two fingers into the blonde writhing before him. He continues to smother attention over Katsuki’s clit with his tongue as his fingers reach exactly where Katsuki had imagined they would, hitting all the right places, abusing his G spot.
“Todo- Todoroki! I'm gonna! Oh fuck!”
Todoroki seems to renew his efforts at Katsuki’s outburst, his fingers pounding into him harder, and Katsuki actually fucking squeals, cumming hard on the other boys' fingers and tongue. His pussy oozes sticky cum, coating Todoroki’s lower face and dripping down his hand while he fucks him through his orgasm. Todoroki pulls his face away. his fingers slowing down but not stopping as Katsuki starts to twitch from overstimulation, trying to push at his hands to get him to stop.
“You want me to stop? That’s a shame...I thought you could handle anything, Bakugo.”
The bait is obvious, even Katsuki, who’s on a different plane of existence can see that. Todoroki’s fingers are still slowly pumping in and out of his puffy pink hole, and it's too much and too little all at the same time. He bucks his hips as Todoroki pulls them out to rub against his over sensitive clit, its ecstasy, it’s everything he never knew he needed, and the only word running through his brain is more. So, Katsuki decides to take the bait.
“I can- ah! I can handle it, this is nothing!” truth be told, Katsuki probably can't handle it. It had taken Todoroki a measly 5 minutes to make him cum, completely stupefying him, but the blonde never backed down from a challenge. Especially not when said challenge includes a pretty boy wringing orgasms out of him. He attempts to plaster his best cocky smirk across his face, but the look of smug amusement he receives in return tells him that Todoroki sees straight through him.
The taller boy man-handles him into a shower stall, gripping him by his hair as he pushes his face into the cool tile wall.
“Tell me what you want Katsuki,” Todoroki practically purrs his given name, never one to ask for permission for anything. “Tell me how bad you want me.”
The words have his cunt throbbing. Katsuki never expected Todoroki to actually be one for dirty talk, would’ve thought that was just his brains wishful thinking since the boy hardly even knew how to talk to people under normal circumstances. This is a challenge though, another competition between the two of them, to see who breaks first. And Katsuki intends to win.
“I’ve been thinking about you all day, Shouto.” two can play at that game! “Been thinking about how you would fuck me, I ran off from our fight to finger myself to the thought of you.”
Katsuki hadn't intended to be so honest, he just wanted to rile shouto up, but once he started it was like word vomit. Shouto groaned at his words, already having freed his dick from the confines of his underwear, rubbing the tip against Katsuki’s pliant hole. But Katsuki couldn’t stop talking.
“Wanted you to slide into me in the middle of the training field, fuck me hard while you had me pinned, I was soaking wet at the thought of it.”
Shouto impaled Katsuki on his cock with no warning, sliding home, knocking the breath out of his lungs. Katsuki couldn’t even moan, the feeling of being so full overwhelming. Todoroki made no effort to move, though, sitting with his cockhead resting snugly against the smaller boy’s walls, just a breath away from kissing his cervix.
“Then beg for it.”
“Wh- no fucking way!”
Shouto gripped Katsuki by his chin, forcing him to turn his head to look him in the eyes. The blonde was stunned, never in his wildest dreams had he imagined his fantasy to be so close to the truth. Whimpering, he stubbornly kept his mouth shut, trying to move against Shouto himself, attempting to entice the other boy into moving without the need for begging. But Shouto’s grip on his hips turned bruising, one hand sliding up to wrap around Katsuki’s throat.
“Beg.”
Shiiiiiit. Katsuki was fucked, he was so so fucked. But still, he didn’t beg. Even though he really, really wanted Shouto to fuck him. He held Shouto’s gaze, trying to put on his best ‘don't fuck with me’ face, but the other boy still didn’t move an inch. So, naturally, Katsuki decided extreme measures were needed in his state of need. He spits in the taller boys’ face.
The silence following stretches on for what feels like eternity, Katsuki even starts to worry that Shouto is going to pull out and leave him high and dry, wonders if he says ‘please’ now will Shouto forgive him and just fuck him already? He’s about to start praying to every god he can think of to let him feel the slide of Shouto’s fat cock inside of him again, when the other boy finally begins to move. Shouto is not forgiving, he is ruthless. His grip on Katsuki's hip and throat somehow tightening more, slamming his hips with what must be all his strength into Katsuki. The head of his dick isn’t kissing his cervix, it’s fucking abusing it, it hurts so good Katsuki thinks he might die.
“Sh-Shouto! Fuck fuck fuck!!” Katsuki must be far too loud, everyone in the entire dorms can probably hear him, but he can't find it in himself to care when he can feel his orgasm building rapidly.
“You’re a fucking brat, Katsuki. Do you feel good? Do you like getting what you want without even having to ask?”
“Yes! Yes! It’s so good!”
The heat building inside of him is unbearable, Katsuki can feel his hole spasming around Shouto’s cock, he's so close.
“Fuck don't stop! I'm gonna cum!”
And just as he is about to tip over the edge, Shouto stops. Because of course he does. Katsuki’s orgasm is positively ruined, and it's probably the worst feeling he's ever felt. His hole is still quivering, the remnants of his previous orgasm still sticky on his inner thighs, and he is so sensitive it's starting to hurt.
He shouts in frustration, tears pricking at the corners of his eyes as he desperately tries to fuck himself against Shouto.
“What the fuck is wrong with you! I was right there, you ruined it you-”
“Maybe you should’ve done as you were told then, hm?”
Shouto pulls out. Katsuki is dumbfounded, this isn't how his fantasy had played out at all.
“Wait! You’re not seriously going to stop, are you?! You haven’t finished either you know!” He pleads desperately.
“I'm fine going without. You’ll just have to sort yourself out I suppose.”
Katsuki feels desperation begin to swell within him, his pleas clawing their way through his gut and up his throat, where they sit uncomfortably large at the back of his tongue. It’s so much harder to swallow his pride, to beg for what he wants, than he had imagined. He has half a mind to punch Shouto in his stupid face, but when he sees the taller boy turn to unlock the stall door, the words stuck within him come rushing out, albeit quietly.
“Please, come back. I need it.” He murmurs, embarrassed beyond belief.
Shouto is at his back again in the blink of an eye, the smile in his voice oh so obvious as he leans into Katsuki’s orbit once again but makes no move further than placing his hands on the blondes' hips.
"What was that?"
“I said please you asshole!”
Shouto slides back in, picking up his relentless thrusts as if he’d never stopped in the first place, forcing Katsuki up onto his tiptoes as he struggles to meet his ass against Shouto’s hips.
“Perfect, Katsuki. Isn’t it so much easier to just do as you’re told?”
Katsuki nods his head deliriously, too far gone to form words all of a sudden, as his entire body is rocked back and forth, his face smashed uncomfortably against the wall as burning pleasure courses through his veins. He registers Shouto muttering things in his ear about how well behaved he is, how happy he is to finally have him like this, but he couldn’t respond even if he wanted to. Shouto somehow picks up the pace even further, reaching around the shorter's broad chest to pinch at a pink nipple, the other hand reaching further down to tease his fingers along Katsuki’s clit.
His mouth hangs open, the noises spilling out downright mortifying. Anyone walking past the bathrooms would probably struggle to tell whether Katsuki was being fucked or murdered with all the wailing he's doing. Shouto must start to think it's too much too, because he sneaks a hand up from Katsuki’s waist to cover his mouth in a poor attempt to muffle the cries he's fucking out of him.
Katsuki pries the taller boy's hand away from his mouth, “Shouto! Please, God, can I- please let me cum!”
“Shit, Yeah, cum all over my cock!”
The words send him over the edge, Katsuki practically convulses as he cums, tears streaming down his face as he writhe’s in Shouto’s arms, quickly becoming overstimulated. But, same as before, Shouto doesn’t relent. He continues to fuck into Katsuki, chasing his own orgasm, his fingers now pinching the smaller boys abused clit.
“S-Shouto! Too much! It feels weird!” Katsuki cries, a pressure building in his abdomen as his fourth orgasm rapidly approaches, but the taller ignores his pleas in favour of pulling out and spinning Katsuki around. He places the blonde’s legs in the crooks of his elbows and holds his body weight against the wall, as he swiftly re-enters and continues to pound into Katsuki’s over-used hole.
“Just a bit more, you can handle it...Good boy.”
Katsuki’s mouth hangs open in a silent scream as he cums, the feeling crashing into him brutally and unexpectedly, his mind goes blank, his body losing control as he gushes all over Todoroki's cock, who is only spurred on by the unexpected release. It feels like it goes on forever, his pussy squirting and twitching around the intrusion, dripping until it forms a small puddle below them. until finally Todoroki releases inside of him with a groan.
When they finally come down from the high, Shouto lets Katsuki down gently, helping him seat himself on the shower bench in fear that he may fall over with his trembling legs. With the post orgasm haze finally receding, Katsuki is left unable to look Shouto in the eye. How could he be so embarrassing? Begging, crying and screaming for Shouto, on the edge of orgasm just from a single touch. His face burns as he buries it in his hands.
“You can go ahead and forget this ever happened, Icyhot, because it won't be happening aga-”
Shouto grips his wrists and pulls them away from his face, crouched down to meet Katsuki’s eyes. A small but genuine smile on his face, a blush dusted over his cheeks. There is a look in his eyes that Katsuki can't quite place, something akin to understanding.
After an eternity of silent staring, Shouto breaks the ice.
“Want to get a shower with me?”
Katsuki releases a breath he didn't know he had been holding, his own smile mirroring the one Infront of him, and nods his head.
