Chapter Text
There was a thud as Shinso's elbow connected to the other alphas' body. He grinned, finally landing a hit after being blocked repeatedly. It was short lived as his opponent hooked a leg behind his and he went down hard, back hitting the blue mat.
Around him his classmates were all paired off in twos or threes. Their fights played out on similar blue mats that littered the college's gymnasium floor. They laughed and tried out things they wouldn’t usually, enjoying the quirkless sparing practice.
He couldn’t enjoy his match, because he was paired with Katsuki Bakugo, who watched him like a hawk for any moment of weakness.
The blond leered at him from above, his smirk boiling Shinso’s blood. He heaved out a breath and stared past— at the ceiling of the gym complex, recollecting his strategy. White pipes and overly large vents crisscrossed and were eventually swallowed by lavender walls.
"Don't tell me you're giving up already." A rough laugh followed.
"Fuck you." Shinso deadpanned in return, not bothering to spur on the idiot with anything more biting. Bakugo would get his— when Shinso had him flat on his back.
He got off the ground, refusing to let any dismay show after being bested yet again. Bakugo didn't even seem fatigued... and he'd been in just as many sparring matches as Shinso. The blonde stretched, pulling on his bicep, carefully watching Shinso with that stupid, cocky look in his eye.
If there was one thing Shinso could admire about Bakugo it was that he hardly ever took his eyes off his opponent. He may have seemed like he wasn’t taking his matches seriously to an outside observer, but Shinso knew that was far from the case.
They tested each other, trading jabs and blocks. Shinso feinted and landed a good blow to Bakugo’s ribs but the follow-up, a kick to his jaw, caught him by surprise and Shinso had to retreat a step to catch his breath.
A stupid mistake. They circled each other for a moment before Shinso went back on the offensive. His opponent mostly understood aggression so he became aggressive, striking once, twice, three times in quick succession, landing the third hit but only barely before he was forced to retreat.
It was for naught, Bakugo surged after him with a growl, shooting out jabs one after the other. It was everything he could do to dodge them. He ducked and spun to the side, Bakugo’s fist only grazing him.
Shinso was patient, he could bide his time… wait for his opening…
Bakugo was right on him, red eyes flashing, not letting Shinso catch a fucking break.
It was infuriating but he’d never let it show. His face was perfectly controlled and serene. Nonchalant even when he could help it.
He dropped to the floor when Bakugo lunged, sweeping a leg towards his opponent. Bakugo dropped, rolling as soon as he hit the floor before springing back to his feet.
Now he looked renewed with determination, no longer smiling. Good. Shinso was finally getting to him. Before Bakugo could regain his bearings he went for his gut, hitting him twice. He doubled over and now it was Shinso’s turn to smirk.
“You're losing your touch. This match is repetitive and dragging. You gonna let me pin you this time?” Violet hair and sleepy eyes lent his drawl some style.
Before Shinso could blink Bakugo was tackling him to the ground. They landed with a hard thud, Shinso cursing under his breath. Bakugo punched the mat just to the left of Shinso’s head. “Shut the fuck up, damn extra.”
He made a point to show just how unfazed he was, smiling and chuckling. “Don't tell me I’m getting under your skin? So easy?” He didn't put his quirk into the questions but Bakugo didn't know that.
Bakugo yelled and brought his fist down again, this time an explosion igniting on impact.
“Hey! No quirk use!” Aizawa yelled, hair floating as his ropes dragged Bakugo off. He didn’t let himself get dragged back easily, kicking and pushing against the bands, cursing up a storm.
He was gagged by Aizawa and just because Shinso knew it would piss him off he got to his feet laughing. “No problem here, teach.” He lifted his hands in surrender, shrugging his shoulders. “I guess I must be getting better if someone has to resort to a quirk to beat me. That’s great news.”
Bakugo yelled louder, eyes practically bugging out of his head, an incomprehensible mess against the bounds.
“Enough! Both of you hit the showers! And if you break anything you’re expelled, THAT INCLUDES EACH OTHER!” Aizawa released Bakugo, who shoved away from the binds and marched off to the locker room, mumbling under his breath the whole way.
Shinso made it into the locker room second and Bakugo whirled around to face him, still fuming. He was already undressing, shirt tossed to the side presumably so he could go shower, though he seemed a little distracted now. “You! Damn eyebags! What the fuck was that?”
Shinso barely spared him a glance, making his way over to his locker. “You really should go shower, you're stinking up the locker room with your hissy fit.” He pulled his shirt off over his head.
Bakugo, of course, ignored Shinso opting instead to march over. He slammed his palm into Shinso’s locker. “You were using your quirk too, you bastard!”
Shinso didn't flinch. “I have no idea what you're talking about. I'd do no such thing.” Bakugo slammed his other hand to the other side, growling. Now Shinso turned to face him, smirking. “I really am getting under your skin, huh?” He laughed and ducked under Bakugo’s arm.
“Hey! I'm not done with you.”
He turned to follow but Shinso turned on his heel at the same time so they were face to face, a little too close for comfort. He smiled, tilting his head to the side, it was all too easy. He ran a hand over his neck. “Why are you following me? You want to hit the showers together?”
“What? N-no.” His mouth opened and closed again like he was looking for an insult good enough, cheeks tinting pink.
The sound of voices made them both turn as their classmates approached on the other side of the door. Shinso walked away before Bakugo could turn back, calling behind him. “You lucked out, hothead. Next time I might not be so nice.”

Bakugo grunted when Shinso pushed him against the door, caging him in. His eyes flashed dangerously, betraying his pent up frustration. “Take it out on me.” Shinso said, pressing a leg between Bakugo’s and grinding slowly with his knee. “Or should I take it out on you?”
“I fucking dare you.” Bakugo practically spit in his face, a fleck of it landing on Shinso’s cheek.
He lifted a thumb to it, collecting the spit and meeting Bakugo’s glare with one of his own. Without a word he brought the thumb to his lips and sucked it off. To his satisfaction he could see a familiar red hue flush under Bakugo’s skin. But it was Bakugo who made the next move, hooking a hand around Shinso’s neck and connecting their lips like a man possessed. Hot skin burning into his.
Bakugo pulled away briefly. “Let’s make this quick, I got shit to do.” Then he was on him again, hands making quick work of Shinso’s button up. He took it off and spun them both. He was always tugging at Shinso, so damn pushy. Bakugo stumbled back into the bed, peeling his own shirt off once he hit the mattress.
“Then why do you still have clothes on?” Shinso quipped back, undoing his pants and stepping out of them when they hit the ground. He kept his movements deliberate and slow to tease the other Alpha. Bakugo was impatient as shit and messing with that was one of Shinso’s small happinesses in life.
“Shut the fuck up and get over here.” He wasted no time pushing off his pants and boxers.
Shinso didn’t stop to admire the view but he probably should have. If it was anyone else besides Katsuki Bakugo he would have wanted to linger in the moment as long as possible. But this was just business, and the body came attached to the loudest mouth he’d ever met. He went to the bed, climbing up to follow Bakugo who was scooting back. They didn’t kiss again, and oftentimes didn’t kiss at all. His lips went to Bakugo’s shoulder instead, teeth almost closing down but for the fact that he knew Bakugo would burn him alive if he left a mark. His hands slid up Bakugo’s abs and ended resting on his biceps, cords of muscle flexing beneath them.
Shinso straddled his thick thighs, groaning at the friction when his cock rubbed against them. He was hard enough that anything felt good, still worked up from earlier that day. Shinso didn't have the patience for anything more involved, he wanted to cum and he wanted to go home.
He shifted up until they were rubbing together. Holding his hand under Bakugo’s mouth, and looking at him expectantly. “Spit.” And Bakugo did, Shinso following the act before he gripped both of their cocks together and started to thrust into his hand. The little bit of wet was just enough to make the slide easier and soon Bakugo was moaning with his rough voice and writhing under him, pushing into his hand too. Shinso’s fingers were long but they couldn’t close all the way around them.
It was enough though, because not only did he have his hand, he also had Bakugo’s cock, warm and throbbing beside his. Every thrust brought waves of warmth to his stomach, every moan from Bakugo made Shinso grind into him a little harder.
Their bodies slid together like that, more hungry than anything else. Hungry for the friction, the competition, and the release. Bakugo tried to flip them and be on top but Shinso wasn’t going to give in so easily today. He rested his other arm like a bar across Bakugo’s chest, using it to hold himself up. The weight pinned Bakugo who focused instead on bucking his hips up, so they could move against each other faster. It nearly hurt but it was also so satisfying that Shinso didn’t want to stop and find lube or something else that would make the slide better.
“If you’re gonna... Be on top then at least put your back into it.” Bakugo grunted, sweat beginning to bead up on his forehead and pool in the dip of his stomach. Shinso knew the taste of it, salty and slightly acidic.
“Shut up, Bakugo.” He said between breaths.
“Make me.”
It was so juvenile but Shinso fell for it anyway. He could never help himself from rising to the challenge. Not when he knew how to make Bakugo shut up. He pulled back, releasing Bakugo from his pin and dipping instead to run his tongue over Bakugo’s stomach, collecting the sweat that pooled there.
Bakugo always smelled like smoke. Notes of tobacco and amber mixed with something burning and sweet, sugary caramel perhaps. Underneath there was warm cinnamon. It was hard to pin down but it wasn’t harsh or overwhelming, it was just distinctly him, and now the smell was all around Shinso, filling his senses.
He continued licking down to Bakugo’s cock, wrapping his fingers around the base and giving a few languid pumps to collect the precum that was spilling out before moving in to sink his mouth halfway down. He pulled back, letting spit dribble out of his mouth and over the head. He collected that too with his fingers, keeping up the strokes while he went to work with his tongue. Licking in circles and up and down in long stripes, before taking it back into his mouth and pushing himself down as far as he could.
Bakugo let out a curse, wrapping his calves behind Shinso’s head and using his powerful legs to push his head down even further. Shinso’s nose brushed against skin and hair, eyes watering and throat constricting against his will, making him gag. But Shinso came up smiling. He let go, moving back up. “Wow, twenty whole seconds of silence. A record.”
“I was just trying to enjoy the view, you look good with your mouth full.” Bakugo smirked, “Now get back to grinding against me.” He demanded, impatient as always.
Shinso just rolled his eyes, grabbing both of their lengths and rolling his hips as well. There was much more slide now that he was spit slick. Bakugo hissed, grinding against him to match each of Shinso’s movements. That was the end of their verbal back and forth, now they were both too focused on the friction.
Finally, the quiet took over his head, everything focused down to a singular goal, chasing the feeling that was building inside of him. Getting off was nice, and Bakugo was hot there was no denying, but in truth what Shinso was looking for was mostly this part. His head finally shutting up. All he needed to do was help get Bakugo off. All he needed to take care of was pleasure. There was no way to fail.
His ministrations were probably a little too good. Before long Bakugo was tensing up, his head tipping back as he came. Shinso didn’t bother stopping or speeding up, his body driving him towards a singular goal. He kept his hand around both of them and kept fucking his fist. He was so close now, he could feel himself winding up like a spring. Somewhere, distantly, he was aware of Bakugo muttering curses under his breath, aware of his sharp breaths and how he clutched the sheets. He could even feel how some of his cum had dribbled down his fist, sticky and wet.
His mind wandered briefly to the background noise, to Bakugo writhing beneath him… at Shinso’s mercy. Then suddenly his own orgasm took him by surprise; sooner than anticipated, his mind suddenly blanked out in a flash of white. He came all over Bakugo’s stomach, some splattering onto his chest. When they were both done Shinso let go and rolled off, collapsing next to him. White beads of cum pooled in the divots of Bakugo’s abdomen, a filthy sight.
Shinso let out his breath in a huff, muscles melting like jelly into the feeling. “Fuck, I needed that.”
“If you gave me rope burn you’re dead.” He replied, breath heavy.
“If I had a quarter for every time you threatened my life I’d be rich by now. Not very heroic of you.”
“Yeah yeah, if I had a quarter for every time you said something stupid I’d be loaded too. And next time don't take so damn long, you left me sensitive as shit.” But there was no real heat in it. “Now get out of my room, I gotta study for the math test tomorrow.”
The walk back to his dorm room was blissfully silent. No sounds inside or outside his head. It was this feeling that he really craved, the emptiness. After he made it back to his room and cleaned himself up, Shinso sat down in front of his textbooks and got to work. He also had a math test the next day, the same one as Bakugo in fact, but the thought of studying together was laughable. Why would he willingly spend more time around someone he disliked as much as Katsuki? He’d rather swallow dish soap.
Too soon the silence grew loud once again and he put headphones on, pounding bass and eerie synth filling the spaces math didn’t take up. He didn’t notice someone knocking on his door but that didn’t seem to matter because Kaminari caught his eye as he came barreling in without an invite, collapsing on Shinso’s bed.
He was used to it by now and finished up the problem he was on before moving the headphones to hang around his neck. “Can I help you?”
“I’m so gonna bomb the test tomorrow,” the omega lamented.
“Have you studied?”
“Pft of course not. Unless…” The omega wiggled his eyebrows.
“Not a chance.”
“But! C’mon! Hear me out-”
“Nope.”
“Shinso! Please… do you want me to fail?” He whined.
“I don't really care actually.”
“You're just as bad as Bakubro.” He mumbled.
Shinso didn't even answer, he just glared and turned back to his books.
“I already asked him and he shot me down too.”
“Sounds like a personal problem.”
“It is a very personal problem and when I'm homeless and jobless post grad and I'm bumming off you it'll be your problem too.” He sighed, the whole world seemingly on his shoulders.
“You've had a week and a half to study, Kaminari. What do you want me to do, magically put all the answers into your head?”
“Maybe? I don’t know, can you do that? Don’t answer that… speaking of Bakugo… what's up with you two anyway?”
“Hm? What do you mean?” He asked, feigning ignorance and concentrating on his work.
“Oh come on, everyone watched you two almost tear each other apart earlier. Aizawa was fuming.” Kaminari laid on his back, head hanging off the bed so he was looking at Shinso upside down.
“I was just sparring, he’s the one who can’t hold his temper and used his quirk.”
“But why do you have to goad him on so often? He’s really turned a new leaf and been trying to be a team player and then you guys spend five minutes together and it’s like BAM same old Bakugo.”
Shinso thought over his answer, mulling the words in his mouth and wondering what to say that would satisfy Kaminari’s irritating curiosity. “I just… don’t fucking like the guy. I don’t know what else to say.”
"That's obvious enough even though it doesn't smell like it." Kaminari’s face pinched in distaste. "You still reek of him from earlier. Don't you shower man?"
"Must've slipped my mind."
