Chapter Text
Katsuki is sick and tired of his friends little interventions whenever he falls into a rut.
He hates when people can visibly notice his failures or lack of focus. It's not like it's his fault he had fucking hormones and literally no way to fix this shit. There isn't anyone he finds attractive that he's willing to admit and anytime he goes porn searching, he always finds himself on videos with a lack of girls. Post-nut clarity really gets to him afterwards to the point he stopped bothering with that too.
He watches as his four moronic friends wrestle on the floor for an Xbox remote to determine who's going to play next. Their Detroit Smash Unlimited frenzy has been going on for weeks now, and to be frank, Bakugo was over it already. He's always been good at video games, and anytime he masters them he has a hard time finding the motivation to play them again.
"I'm leaving." He grunts, picking himself off the floor, becoming visibly irritated when his 'friends' start whining in his ear.
"Common Bakubro! You always dip on us!" Tape face mumbles out between chews.
Bakugo would never admit it, but he's always been impressed that Sero enjoys hot foods for snacks. It's always been the best reason for keeping him around.
Pinky is next in line for complaints. "You are suchhhh a party pooper!" she slurs.
She's become more of a handful this past year then Bakugo likes. He's been seriously considering telling Kirishima to get her back on track or get rid of her. Ever since they started third year and could legally buy alcohol, that all she's been doing. Sure bringing it on campus isn't legal, but no one hardly ever checks the dorms anyways, and keeping things hidden is what kids with quirks are best at.
Bakugo's eye starts to twitch and Kirishima picks up on the sign that it was time for Bakugo to leave.
"Hey man, why don't we come get you later tonight when it's time for the movie? It's Shoji's turn to pick and you've always liked the action ones he chooses! I'm sure the whole class is gonna behave too!" Kirishima walks with Katsuki to open the door and let him out. It's not exactly to save Bakugo, but rather the rest of their friends from the explosion they both sense coming on.
"Whatever. I'll text you if I'm coming, don't bothering showing up."
He shoves his hands in his pockets and stomps as he leaves. Once he knows he's out of ear shot though, his footsteps lighten and his shoulders hunch over.
He doesn't exactly enjoy his façade anymore. It started getting taxing when he realized how fruitless it was with his friends, and that his reach was getting slimmer and slimmer as the years went on. He grins thinking about the one person he knows he can have a hold on forever though.
Deku.
He thinks of how perfect Deku could be. Crying underneath him, whimpering when he hears Bakugo's quirk, cowering behind him. Katsuki loves feeling powerful over Deku. He isn't a bully anymore, no. He apologized years ago and he and the nerd had been closer hero partners then he would have imagined, but it was never bad. Deku always reminds Bakugo that he will do anything for him.
He's well aware that quirk wise, Izuku is so much stronger then he is. It hurt his pride the first time he ever admitted it to himself, but he's grown to appreciate he has a rival he can surpass as powerful as Deku. It's not something he could have ever seen for himself when they were younger. He wanted Deku to stay behind him, to keep admiring him from a distance where things were safe, where Deku would only have eyes for him. Auntie always asked Katsuki when they were kids to watch over Deku and keep him safe.
Even to this day he feels that obligation. His quirkless nerd. His number one fan.
His Deku.
Sure, all those original plans were out the window, but Deku is still his number one fan. He even helped Katsuki plan out different winter outfit designs to make his quirk work better while giving him better mobility.
Bakugo sighs as he walks past Deku's dorm room as he makes way towards his own. He wouldn't mind a training session or a good spar with the nerd.
When they were going head to head with no quirks it was always Bakugo's win. He was slightly taller, noticeably bigger, and a lot stronger. He had worked hardest on building muscles, especially during their second year. He and Kirishima worked extremely hard at the gym every night they could, and during summer breaks he would drag Deku along with him since he was close by. He remembers many of those gym nights vividly. Deku drenched in sweat, struggling to keep up, groaning as he lifted the heavier weights.
He shakes his head and keeps walking, feeling the slightest twitch of his cock. He started working out with Deku more and more just to hear the noises he would make.
It made him sick to his stomach the first time he ever masturbated to the thought of Deku. It was during middle school, and the only reason he remembers so vividly is
because the very next day he said something so awful to the nerd he had yet to forgive himself for it.
He didn't want to be gay. There were very few gay hero's at the time and homophobia was the norm. He held that secret with him until Kirishima caught him with a boner in the locker room. He walked in for the last bit of an argument Bakugo was having with Deku, and as Deku stormed out past Kirishima, Bakugo was struggling to nurse his cock down. Kirishima made him feel less insecure about it after giving him some space to finish up, telling him that even he swings both ways and that it's 'manly' or some shit.
Kirishima and he were always platonic, the both of them helping one another with the insecurities and working towards their goals towards impressing their crushes. Bakugo felt rather close to his friend when he walked up to him one day and begged Katsuki for help bulking to impress Kaminari. He never pegged Kiri as someone who might dig a twink like Pikachu, but he helped him regardless. It had been proved fruitless however; Eijirou had yet to confess even after Denki came out to the class. But Bakugo never pushed his friend. He only reassured him and promised to help him figure it out.
It was the least he could do for him anyways. Kirishima had helped him plenty before. If fact, Kirishima even made a point that Bakugo might only be gay for Deku. Or even more so, have romantic feelings for only Deku. It clicked for him that, that was pretty accurate. But he was still worried.
It's very possible Deku still views things the way the world did when they were kids.
The times may have changed where that might be acceptable, but it only makes things harder for him. Plus, he knows the nerd isn't gay. He can never be with Deku, so if he can settle for being a hero beside him then so be it.
Focus on the gym or shit dumbass. He wants to jerk off, not lose his erection to gay panic.
As he makes it to his dorm room and is turning the door knob, he swears he can hear those same noises Deku makes loud and clear. He palms his cock, ready to give himself another non-satisfactory orgasm when his jaw nearly drops to the floor.
Kneeling, naked, on all fours in the middle of his floor is Deku.
His two fingers are pressed deep inside his ass and he's panting loudly. Small moans are escaping his mouth, his eyes shut tight as he slips his fingers in and out at an agonizing pace. One of Katsuki's shirts is under the nerd, his fist gripping it tightly to his face as he nearly drools on it.
Katsuki doesn't even bother to look down. He knows his dick is completely hard now.
The nerd doesn't even notice him until he slams the door closed. Katsuki is grinning ear to ear at the horror painted on Deku's face.
Bakugo lunges forward before the greeny can move and locks onto his neck with a strong grip, pushing Deku further into the floor and Katsuki's shirt. The nerd fucking moans too at the sudden force, making Katsuki's cock throb. He leans over on one knee until his lips are close enough to touch the nerds ear.
"Whatchya doin, Nerd?"
****
Izuku is stressed beyond belief.
He's been hung up in his room for the past four hours trying to mix Blackwhip and Smokescreen together to form a solid barrier. It was All Might's suggest to learn new ways to use each of the different quirks before graduation. There was nine months between graduation and now, but for Izuku is doesn't feel enough.
He falls on the floor when his seventeenth attempt doesn't work any better then the first. He feels so frustrated and annoyed.
But he was killing time for a reason.
He checks his phone and notices its already 4:50.
Kacchan's been gone for twenty minutes now, the coast should be clear.
Izuku had overheard Kacchan and Kirishima this morning talking about meeting up to hang out with their friends in Kirishima's room. Izuku was ecstatic when he heard this, and devised a plan. He really wants to spritz some of Kacchan's cologne on the t-shirt he borrowed (and never gave back) a few weeks ago. It only smells faintly like Kacchan now and he doesn't want it to go away.
He can't admit it, but he loves to masturbate while laying on top of the shirt, taking deep breaths of Kacchan's smells which at this point is starting to turn him on, on its own.
He's had a crush on Kacchan for as long as he could remember. He always admired the blasty boy since they were kids, but Uraraka finally helped him put a label on his feelings during their first year.
"So your heart beats frantically when your anywhere close to him, you always feel hyper focused on him, and even the thought of losing him makes your body ache?" Ochako smiles softly as her head tilts to the side. Izuku knows he being made fun of for being so blind on the matter, but he can't help it. He's never had a crush on someone before.
"Ha ha-I mean, yea, ha, I-I guess so." He stumbles shyly, cheeks flushed to a light pink.
"So you like Bakugo!"
Izuku is almost positive he activated his quirk accidentally as he rushes to slam a palm over her mouth. He can feel her smile and lick his hand until he pulls away, wiping the spit on his pant leg and looking disgusted at it.
"Oh please, we both know these rooms are sound proof, relax."
"They're sound resistant Ochako, please be mindful." Izuku hisses softly.
"Fine, Fine!" she throws her hands in the air playfully, "but at least admit you do like him."
"But...I don't know if I can say I like him. I mean, he hates me.." Izuku trails off as he contemplates the confusing relationship he has with his childhood friend.
"They don't have to like you in order for you to like them silly! And anyways, we all know Bakugo doesn't hate you, if anything, I'm pretty sure he treats you the best out of everyone here."
Steam nearly pours out of Izuku's ears when he hears that.
Kacchan treating me the best? That can't be right.
"And it's okay to like guys! You don't really have romantic feeling for others in general Deku, we can all tell you see us like brothers and sisters. But Bakugo is different. If you like him, then own it! He's not exactly nice, but I can see you guys working it out one day."
Her big smile is what relaxes him.
Maybe he can like Kacchan and keep being a hero at the same time. It might make things tough at some point; Kacchan is going to have a pretty wife and super powerful children, be an awesome hero, and maybe even outdo Izuku one day. But watching from the sidelines might be all the Izuku needs as a hero.
After that day with Uraraka, Izuku relished his new found crush alone. He watched with big green eyes at everything Kacchan did. He got jealous when Kacchan started working out hardcore with Kirishima, but forced himself to brush those aside.
How could he be a good friend to Kacchan if he was always jealous of Kacchan's girlfriend or even wife?
After some time Kacchan even asked Izuku to work out with him, and he realized that being jealous wasn't worth it if he could spend time like that with Kacchan instead. Their workouts often left them in awkward positions or situations, all of which Izuku would embarrassedly hide or run away from to avoid getting caught.
He's pumped out one too many boners in the gym bathroom then he would ever like to admit.
But third year is really getting to Izuku. It's his last year of school with Kacchan, and his fears of getting to spend so much time together are growing daily.
Every time he asks Kacchan which agencies he wants to apply to, he brushes it off and says he's still looking. Izuku really wants to apply to the same places in hopes that they can go together. At some point they even had an argument in the locker room about it. Izuku should have known better though. Their first all out brawl in the locker room lead to him having a massive boner and fuming out of the room thanks to Kirishima's unplanned entrance.
Izuku's cock twitches at the thought of such an old memory. That was the first night he ever tried to finger himself, and ever since it was the only way he could cum.
Izuku places his phone down, grabbing a small bottle of lube and the shirt, growing very impatient after giving himself a boner. He jumps off his balcony and Full Cowling's over to Kacchan's. He's luck the door isn't locked and he slides in undetected. He searches Kacchan's room for the bottle of cologne until he spots it on the top of the dresser.
The first spritz on the shirt smells phenomenal. Kacchan has great taste in scents, picking out one that mimics his natural odor of sweet and husky at the same time.
The first deep breath he takes makes Izuku rock hard. His cock is throbbing in his boxers, already bulging out visibly under his shorts. He glances at the door and notices that it's locked.
I really shouldn't do this here... fuck it.
Izuku rips off his shirt and rolls his nipple between his fingers, groaning when he pinches it tightly. It feels good, good enough he's already leaking precum, but he knows it isn't enough. He shimmies out of his shorts and boxers, pushing them under the bed and kneels face down into Kacchan's shirt. It smells heavenly, and when he closes his eyes he can practically picture Kacchan there, doing these perverted things to him.
He lubes up his fingers and starts by shoving one into his hole all the way down to the knuckle. He moans.
If only it were Kacchan, he thinks, shoving a second finger in, stretching his ass out.
The rhythm is fast and shallow, but it's the best he has. He grips onto the shirt and pulls it up closer to his face, taking another deep breath, pulling him closer to his orgasm. He's ready to touch his own aching cock, he's ready to finish and leave, he-
The door slams shut.
To Izuku's horror, Kacchan is standing at the door, staring at him.
No, no, no, no, NO.
He feels frozen, he can't move. Within seconds Kacchan is surging forward at him. Izuku still has his own fingers inside of him, unable to move at the complete shock of Kacchan catching him.
He moans loud when Kacchan grips his neck tightly and forces his further into the ground, kneeling down to whisper in his ear.
"Whatchya doin, Nerd?"
Izuku whimpers. The heat of Kacchan's voice, the strong hand wrapped around his neck and his fingers still buried deep inside of him are too much. He cums right there, all over the floor. Panting, his fingers slip out and his whole hand drops to the floor. Kacchan is still pushing him down, but he doesn't fight back. He feels the grip getting tighter to the point Izuku can't turn his head to look at Kacchan.
"Did you just cum?" Kacchan's gruff voice echo's in Izuku's ears at the realization. There's a light shifting behind him before Kacchan starts chuckling.
"Ha, what a fucking prevert. All because I pushed you down huh?"
"N-no!"
"Then what the Fuck are you doing in my room?"
Izuku falls silent. He doesn't know what to say. He's embarrassed beyond belief, and yet the situation has his cock aching, already trying to get hard again. Apparently Kacchan has noticed too because he gives Izuku's cock a flick with his fingers. Izuku whimpers in response.
"What a perv..I thought that purple perv from first year getting expelled shut all the perverts down, but here you are Deku." Izuku shutters at the way Kacchan says his nickname. The way it rolls off his tongue like Izuku is a sultry pervert makes him half hard and leaking again. He squeezes his eyes shut and whimpers again.
"Please Kacchan.." Izuku isn't sure what exactly his begging for. It's a solid toss up between Kacchan getting off him, and Kacchan getting him off.
This time when Kacchan leans down, his lips brush ever so slightly against Izuku's ear, earring a quiet moan.
"You want me to fuck you, Deku?" There's a slight pause between the two of them.
I s this really happening? Is Kacchan just saying that to mess with me, or is he really going to fuck me if I say yes?
Just the thought alone is enough to make him shutter. He freezes when he realizes Kacchan's fingers are tracing down Izuku's back, just coming short of his hole every time. He starts to whine every time Kacchan purposely misses and moves his fingers back up; he's still waiting on an answer.
Izuku nods. His ears are burning, his body is hot, and he can feel Kacchan's body behind him.
That's all it takes before Kacchan is man handling him up into the bed, throwing him down on his back. Izuku would be lying if he said he isn't checking Kacchan out as he undresses. Those broad shoulders, touched up hair line, small scars that litter his body and make him only that much more attractive.
Sure Izuku has seen Kacchan naked a bunch of times as kids and occasionally in the locker room, but this was different. Kacchan's red eyes are full of lust, his gaze is intense, and his body is preparing to pleasure Izuku. Somewhere in the back of his mind he's screaming at himself to make it stop, but his lust and desire are driving him.
He wants to seduce his precious Kacchan to the point fucking him isn't going to be up for debate.
Izuku grins as Kacchan kneels between his legs, spreading them apart on purpose just for Kacchan. Izuku was thinking he might see his rival falter or change his mind, but his actions only fueled the blasters fire. He shoves a finger into Izuku's hole, making Izuku scream in pleasure.
"Ha, what's this? You're already loose? What a slut." He shoves another finger in, pumping them vigorously. Izuku goes to touch his own cock but earns a hard smack from Kacchan.
"Don't fucking touch yourself before we get started stupid Deku. I'll fuck you soon enough."
Izuku watches as Kacchan's eyes the room, slipping his fingers out to get up and grab something
A left over uniform belt.
Kacchan's eyes are sparkling as he kneels between Izuku's legs once more, holding the belt up.
"Give me your hands."
Izuku hesitates for a second, but Kacchan doesn't move. He waits patiently despite the situation for Izuku to come to him before tying his hands together. Kacchan pulls at the restraints and then looks at Izuku.
"Is it too tight?"
A slight tug and a few shifts of the wrist let Izuku know that its secure but not unbreakable. He could use his quirk if he really needed to.
"No, it's just right."
Kacchan grins.
"Good."
He bites Izuku's thigh as he fits a third finger inside, curling them to find Izuku's prostate. The first time he hits it, Izuku nearly cums. His back arches, toes curl, and he moans deeply. Kacchan smirks and grips his cock, covering the slit with his thumb, continuing to bite and suck on Izuku's thighs. Izuku's eyes begin to tear up and being denied an orgasm.
"Ka-Kacchan, please, p-please let me cum." He cries, covering his face with his arms. He peaks when he feels Kacchan's fingers slipping out of him and his hand removing itself form Izuku's cock. Katsuki is leaning over Izuku, pushing away his arms to nibble on the greens neck and jaw.
"How do you want to cum Deku? Beg me for it."
Izuku gasps when Katsuki slaps his dick against Izuku's puckering hole. He squeezes his eyes shut again and more tears fall down his face.
"P-please..fuck me...Please fuck me with your cock KacchaaAA-"
He can't finish before Katsuki is slamming his dick inside of Deku, setting a brutal pace from the start. It only takes him a few seconds to find the nerds prostate and begin deliberately slamming into it with all his might. He can feel how tight Deku gets with every hit, driving them both closer and closer to their orgasm. Katsuki bites back a moan when he looks down.
Deku is moaning out sobs, tears wetting his face as he throws his head back in pleasure. The nerd looks so fucking good under him, his ass getting pounded by Katsuki's dick. For a brief second Katsuki thanks the gods he just happened to walk in on Deku like this. It's all feeling like a dream to Katsuki until Deku throws his hands around him to pull him closer. He ducks his head into the crease of Deku's neck and bites down, hard, earning a hard squeeze around his dick that feels amazing.
"You like when I bite you Deku? You like when I fuck you and bite you Deku?"
"y-yes, yes, fuck Kacchan, I love it!" Deku screams in his ear, bucking his own hip in time with Katsuki's thrusts. He can see the nerd is close and reaches down to grab Deku's cock, pumping it furiously. His own orgasm is right there. Deku screams as he cums in Katsuki's hand, and Katsuki looks up just to push himself over the edge with Deku's orgasm face. He releases inside of Deku, thrusting until he's completely dry, collapsing onto his elbows to prevent himself from crushing the other boy.
They stay motionless for a few minutes, both of their breathing leveling out before Katsuki remembers the belt. He lifts himself up and looks down.
Deku looks fucking spent underneath him. His eyes are shut and it looks like he's sleeping. His wrists are bound, there's cum on his chest, and his legs are still slightly bent from Katsuki still being between them. Katsuki is quick to release Deku's restrains only to realize the nerd really did pass out post orgasm.
Bakugo slides off the bed quietly, grabbing some tissues to clean off Deku's torso and his own hand. Once they're both clean he looks at Deku's oozing hole.
Fuck.
He shifts Izuku's legs until he can slide his finger back inside Deku's ass, gently cleaning out any of the cum he can. Once he's satisfied he throws the tissues out and covers Izuku with the blanket before putting on his boxers and sitting at his desk chair.
Post nut clarity hits him.
"What the fuck just happened?"
