Chapter Text
Kirishima Eijirou hated himself.
Not for the usual reasons. Not because he felt weak or unmanly. No. In that arena, he was building a lot of confidence. He had his internship where he proved to himself, the heroes and the villains that he planned to become a damned good hero. He planned to protect and help those in need, because that’s what he needed to give to the world.
No, Kirishima hated himself right now because his brain and his body had decided to make him the WORST man in the history of heroes.
Kirishima had already gone through puberty (or so he thought). He had gotten taller and became able to gain muscle. His thoughts hadn’t changed very much though. He still prioritized being a hero above all else. He thought girls were pretty, but he didn’t find them to be too distracting.
As fate would have it, Kirishima had finally discovered his “desires”…and they sucked ass.
That’s why, underneath Bakugo during a spar, Kirishima considered letting the blonde blow his face off without using his hardening quirk. An explosion to his dome sounded like what he deserved right now.
“Oi! Shitty Hair! Focus!”
Kirishima wanted to, but he was using all of his brain power to will his penis to ignore this situation. This had NEVER been a problem before. It’s just…he could smell him. Kirishima could smell the sweet musk that came off of him because of his sweat. The smell of caramel and ash and earth and Bakugo. He wanted to bury his nose in it and inhale deeply. The idea of it made his tongue and saliva feel thick.
“OI!”
Kirishima hardened his face just in time for the blast to his face to feel like a warm towel.
“I’m sorry! Just…please move.”
“The enemy isn’t going to move just because you need a break, idiot!”
“I know Bakugo. I just need you to move, though.”
Kirishima was trying to limit his breathing through his nose, but he could tell that he was fighting a losing battle. His mind was racing with the idea of flipping Bakugo over and pushing his nose against his underarm to let the scent take over his senses. He entertained the concept of smelling his shoes and socks after this session. Being able to shove his face against his groin after this battle and stay there…covering his entire face with his sweat and his smell and his taste.
“WHAT THE FUCK?!”
Kirishima would almost find this funny if it weren’t actually happening to him. Still, a stubborn part of his brain thought that it served Bakugo right. He had told the older boy to move. He didn’t, and now they were both sitting there with the clear understanding that Kirishima had popped a boner underneath him. All the red haired male could do was close his eyes and wait for his early death.
“I told you to move! Now, get OFF of me so I can throw myself off of a cliff.”
Bakugo didn’t move, though. His face was contorted in what Kirishima could only assume to be disgust, but he kept his cradling position even when Kirishima knew he was poking his friend’s thigh. He watched as Bakugo appeared to consider something. He glanced from side to side, looking to see if anyone was paying attention to them. Because they had gone further in the arena to avoid hurting their classmates, it did seem that they had enough privacy for Bakugo to relax his face. His eyes softened from angry to curious, and his mouth twisted into something that Kirishima could only classify as a self-satisfied smirk. The blonde boy put both hands on either side of the other’s head and ground his hips down hard .
Of course he moaned, but before Kirishima could even ask, Bakugo was next to his ear.
“Don’t say another fucking thing. I’m coming to your room tonight.”
Again, Kirishima had no time to ask questions before Bakugo lifted off of him and started walking towards the rest of the class. He decided to stay on the ground a bit longer, head spinning and pants tight.
…
After a day of lectures where Kirishima didn’t retain a damn thing said and a meal that he didn’t really even taste, he was sitting on his bed wearing a white T-shirt and some black gym shorts. He hadn’t taken a shower yet, because he didn’t know when Bakugo wanted to come to his room. He considered texting him, but he didn’t really know what to ask and his friend had told him to be quiet. Truth be told, Kirishima was nervous as hell. It was already rough to wrap his head around the fact that he wasn’t straight. He had nothing against people that weren’t straight. He considered himself an ally, and knew that he would be a hero that supported LGBTQ in need. He just didn’t know that he would turn out to be a LGBTQ hero. Again, nothing wrong with that! Just…complicated things a little.
He also was struggling with the idea that OF COURSE his first real and physical crush would be on the angriest guy he had ever met. Yes, he was Bakugo’s friend and YES he was the angriest man that he had ever met. Kirishima realized that the blonde said “die” in response to even the most mundane things, like brushing his teeth or correcting a mistake on their math homework. The red haired boy couldn’t call to memory a time where he had seen Bakugo smile without there being the possibility of bloodshed or conquering behind it. Why? Why not Sero? Sero was funny and nice and would probably be totally cool with his bro having a crush on him. Even Iida (who Kirishima did find to be manly in his own right) would have been a safer bet, blushing and telling him that he was flattered but needed to focus on his studies…but no. It was BAKUGO. The man most likely to try and murder him in cold blood. THAT was the one that had invaded his dreams. Hell, he wasn’t even nice to Kirishima in his dreams .
That was the last part of this struggle. The worst part. Kirishima had finally started to have sexual fantasies, and the ones he was having were gross as hell. Not “look up the porn in incognito mode” gross, but “you will barely even find porn in this category” gross. It was all degrading, and Kirishima hated the fact that he wanted to be the one taking the “punishment”. He wanted to be made to inhale strong, pungent odors. He wanted to be forced to smell sweaty gym clothes and ripe boxer briefs and socks that had been all but punished because of a strong man having to work all day. It didn’t stop there either, because Kirishima couldn’t just be a kinky shit for the smell of a masculine, manly alpha male. No, he wanted all of his senses to be taken over. He wanted to taste that power. God, did he want that. He wanted to lick Bakugo like a freeze pop and he wanted every ounce of the man’s strength on his tongue. The concept of sucking on Bakugo’s dirty underwear or licking his armpit after a hard day of training almost made him want to cry. He would let Bakugo do anything to him if he wanted, and Kirishima knew that to be a fact. In the small amount of time he had started having wet dreams, he had already found himself waking up to ruined sheets off of the idea of Bakugo pissing in his mouth and making him smell his farts through the thin shield of his rank underwear.
BAM BAM BAM
Kirishima actually screamed at the sudden loud noise, but quickly jumped to his feet to answer the door. Waiting on the other side of it was the object of all of his shame and misguided lust. Bakugo looked so much more dominant than usual, his black Punisher shirt and black pajama pants just the right distance from one another for Kirishima to see a peek of his brief band. He wanted to worry that band between his sharp teeth.
“Move, Shitty Hair. I’m coming in.”
There was no protest, because he didn’t wait for an answer. He literally just pushed past and took a seat on Kirishima’s bed, sprawling out with his legs wide open and his arms behind his head. Kirishima knew he should say something, but chose to sit at his desk instead.
The air became thick instantly. Kirishima was thinking so hard that he thought his brain would explode.
“You stink.”
The younger boy floundered. He hadn’t bathed yet, but Bakugo didn’t need to say that!
“Rude, bro! I haven’t taken a shower yet! I was wait…”
Well, fuck. Two seconds in and he was already admitting that he had been waiting for this boy like a little bitch…and he had been.
“Oh? Waiting for what? Me? Waiting to see if I’d pin you again?”
He could hear the venom in his voice, but he couldn’t even lie well enough to fight the blush in his cheeks. That’s exactly what he had been waiting for, wasn’t it? No sooner than he was about to fumble through some statement in an attempt to save face, Bakugo had sprung up and captured Kirishima by his hair and his throat. He was being forced to look dead into red embers while having his windpipe constricted.
“Holy shit, you’re so fucked.” Bakugo said in a way that almost sounded adoring.
“I…I-I…”
“Shut up. I knew. I knew you’d be good. I knew you were strong enough…but I just needed to know that you would take it. That you COULD take it…”
Kirishima felt a greedy tongue lick a devilish stripe from his neck to his ear before a sinful purr finished the sentiment.
“…That you would want it as bad as I do.”
Kirishima mewled at the sudden attention. This couldn’t be his real life. Bakugo couldn’t really be saying that he was sexually attracted to him too. Right?
No time to think. Bakugo released his grip with both hands just to grab Kirishima by his shirt and throw him to the floor. Before he could roll over, the blonde had mounted him and had rolled his hips against his clothed backside. This was the most overtly sexual thing Kirishima had experienced in his life, and he didn’t know what to do. His pride told him he should fight, but his libido told him to arch…and he did.
“God, you’re going to be so fun. The only reason I’m not going to fuck you right here on this floor is because I didn’t bring any lube. Trust me. You won’t wait long.”
Kirishima didn’t have words. That didn’t stop him from grinding back, seeking more friction while biting his bottom lip.
“You’re going to text me every morning when you wake up. You’re going to say good morning to me, got it?”
A nod and another grind against the man above him.
“You’re going to tell me what you think you like and what you know you don’t like. You’re going to tell me how you’re feeling. All through text until we can be alone. I mean it, Kirishima. If you don’t text me, that’ll make you a bad boy…and you don’t want to be bad for me, do you?”
Not that he had really given it that much thought, but in this moment, Kirishima felt like he would die if he was anything that Bakugo didn’t like. He shook his head furiously, genuinely upset by the idea of making the other man unhappy.
“Don’t worry. I know you’re good. I’ve known for so long now. Don’t get upset. Just do what I say, and I’ll make you feel so good, Kirishima.” Bakugo purred, attempting to console the boy who had noticeably tensed after his last sentence.
“Eijirou! Please! Call me…”
“ Eijirou . Do you want to be my good boy?”
Kirishima ducked his head low and all but whimpered at the sound of his name on Bakugo’s tongue. He was certain he could orgasm just like this, being dry humped on the floor like an animal.
As soon as the thought appeared, it was gone. Bakugo lifted off of him and turned him gently. Red met red as they attempted to read one another. Kirishima felt far out of his depth, but he understood that Bakugo did seem hopeful for something. He wanted to express that he was open to this arrangement. Open to anything that Bakugo wanted to try. He was more than willing.
His entity decided that the best way to communicate that was by closing his eyes and sticking his tongue out.
He could hear Bakugo inhale sharply like he had lost all of the air in his lungs. That was followed by a growl low in the man’s throat. This was the right response, Kirishima decided. This was getting his point across.
“Jesus, I want you so fucking bad. I’m going to make a mess of you in every way. Just be patient for me, yeah? Tonight though, let me give you this.”
Kirishima opened his eyes slowly at the feeling of something wet falling over his tongue. Above him, he saw Bakugo slowly dripping his own saliva into his mouth. After the line disconnected, he decided to be more aggressive and actively spit inside. Just watching that made Kirishima shiver and it was all he had to not start jacking himself off right there.
Bakugo wiped his mouth and lifted completely off of the ground, leaving the other boy panting hard and blushing.
“Text me. Tell me everything. Be good for me, and I’ll make it worth it. I’ll make it so good for you.”
“Anything. I promise, Bakugo.” Kirishima whispered.
Before leaving the red haired boy to handle his painful erection, he simply said over his shoulder…
“From this moment on, you better think of a title. I’m only Bakugo in front of these extras we see every day. You and me? I get a title. I’ll let you pick. Sir, Master, Daddy…whatever. Katsuki if you ever top me, but never again will you look me in my face and call me something so casual. I plan on owning you, little boy.”
Then he was gone. No time for Kirishima to think.
