Chapter Text
Bakugo didn’t know how he ended up in Kirishima’s arms in the middle of the corridor. He was holding on to his friend for dear life, his legs suddenly weak and his body shaking, in a wave of warmth that he was not supposed to feel on a random Tuesday afternoon.
Kirishima was looking at him from above, surprise and panic in his eyes.
“Bakugo! Are you okay?! What happened?”
He would have liked to know too, actually. One second he was walking down the hall, sandwich wrapper in hand, headed to his room to get changed after lunch and the next Kirishima said hi to him and suddenly he was collapsing.
“Bro!” Kirishima called him again, pulling him back up onto his feet. He put an arm around his waist and that was enough to make Bakugo’s situation painfully obvious.
Bakugo felt himself blushing, knowing Kirishima also noticed his erection springing to life through the soft fabric of his sweatpants. “Shit. Take me to my room, dumbass. Quick!” he hissed, already panting from that warmth pooling in his lower stomach.
Kirishima didn’t move for the longest moment, keeping on staring at him. Bakugo was glad he didn’t have to repeat himself when, finally, the redhead peeled his eyes off him and waddled with him to the room.
“Man, this is totally weird, I saw you being fine a second ago. What happened to you? It’s as if you are under some spell.” Getting those words out Kirishima stuttered a bit and it only took a glance in his direction to notice that the tip of his ears was tinged red.
Bakugo blamed his heart skipping a beat entirely on the condition he was in. There was no need to acknowledge that for a fleeting second he had thought his friend was really cute. “Well…” he started, as they stopped to open the door. “I might have been cursed by a bunch of girls.” He groaned, noticing his voice lost his usual edge and was starting to sound weird.
“What? Don’t tell me you got in a fight in the cafeteria again.” Kirishima chuckled nervously as he helped him sit on the bed. His fingers lingered on his arm a moment too long, or maybe he was just imagining everything. He was so turned on that every time his skin brushed against Kirishima’s he got shivers down his spine.
“I guess. I pushed this one aside, she was taking way too long to move and I was hungry…”
“You always are extra cranky when you’re hungry,” Kirishima nodded understandingly.
“Yeah.” Bakugo didn’t know when they became so close. But if this guy noticed something like that without him ever saying anything, they must have been hanging out an awful lot. Thinking back, it was actually rare to have been at lunch without Kirishima. “You weren’t there to apologize in my place for spilling her drink. I’m not a pushover like you. Loser.” He tried to play his condition off by smirking sarcastically at him, to prove he still got it despite being horny out of his mind.
“Sure, bro, but you wouldn’t have been in this situation-” He gestured loosely at the tent in the blonde’s pants, not without blushing and shifting his weight from one leg to the other. “If you had been ‘a pushover’.” He even had the audacity to make air quotes.
Bakugo grabbed a pillow and tried to hide his crotch, smacking Kirishima’s hand away in the process. “Can you not?” He tried to give him a menacing look, but with the way he felt his cheeks burning up, he knew he was failing. “Anyways,” he swallowed hard. “Her friends asked me to apologize and I told them to fuck off. Suddenly this bitches’ eyes were lighting up pink. She said something about how her quirk is wasted on me 'cause no one likes me and I'm gonna die alone." He was never gonna admit that in public, but he had liked that she had the guts to insult him like that. Feisty little thing. If he wasn't pretty sure this whole ordeal was a direct consequence of that encounter, he would have appreciated it more.
Kirishima chuckled again and sighed. “This is karma coming to bite you in the ass, Bakugo. I keep telling you to be nicer to people! Maybe then you wouldn't get attacked by strange quirks. At least it doesn’t seem life threatening or anything. You should be fine if you just rub one out.” His teasing smirk made the feeling deepen in Bakugo’s gut and he let out a rather embarrassing noise.
Shit, way to make it weird. Unfortunately, he couldn’t take back a moan like that, nor the fact that his dick had been painfully hard for a few minutes already and didn’t seem to be going down anytime soon.
What he wasn’t expecting, looking back up at Kirishima, was that hungry look in his eyes. Bakugo could tell he was clenching his jaw and his fists to the sides of his body. His eyes trailed down, lower.
He could have been wrong but… “Kirishima…?”
The redhead turned his gaze away quickly. “Shit, I’m sorry,” Bakugo could clearly see his Adam’s apple move as he swallowed. “I’m just gonna leave…”
Bakugo’s brain froze for a moment. There was no way he could ever do something like this with a friend. Right? It wasn’t normal. He was not into this kind of things, it was way too much, way too open in a way that went completely against his morals.
But that damned quirk was setting his lower stomach on fire at just the thought of actually doing it. Just the idea of Kirishima staying there, next to him as they both took care of their… It wasn’t as if they had to touch each other.
His head was spinning. Yeah, there was nothing wrong with that. They were already there. They were friends. And if he had to do that in front of anyone, Kirishima would have been his first choice. His only choice even.
Kirishima turned around and only made one step towards the door when Bakugo’s body moved on his own, grabbing his wrist.
Kirishima looked completely taken aback when he turned around again. “What…”
“If we are both like this,” he said, planting his eyes on Kirishima’s face, challenging him. “We can just take care of it together.”
The silence that followed his words felt like it was never going to end. Kirishima was not saying anything, just kept staring at him with a dumbstruck look on his face.
He fucked up. He said something he shouldn't have and ruined their friendship forever. Kirishima was never gonna forget this, he was gonna be weirded out by him every day 'til graduation.
Not even the dread he was feeling was enough to dampen his arousal, he felt like he was going insane, holding on to Kirishima's wrist like a lifeline. He could feel his pulse where his fingers were touching, fast and panicked. Could he calm himself down enough to reassure Kirishima? Take those words back and send him away. Brushing everything under the rug and moving on from that seemed like the best course of action. Eventually that jumble of emotions cleared enough to let him find his voice again. “Fuck it. It was just a stupid suggestion, you can go- “
“No!” Kirishima blurted out a bit too fast, looking flustered. “I mean, it’s okay, it’s not a bad idea. Friends do that all the time. And I- I like you. As a friend, obviously!”
“Obviously,” Bakugo repeated, unimpressed and maybe even with a touch of bitterness. Wait, what was that? He was struggling to focus with his blood all gathered down south, but he had the impression he felt as if he got stabbed at those words. Towards Kirishima, did he…?
Kirishima sat on the bed next to him a bit too forcefully, interrupting his train of thought. “Do you…” he cleared his voice, gripping firmly his own thighs. “How do you normally do it?”
“What fucking question is this? I just jerk it,” he blurted out, trying to sound angry. “I just use a glove to prevent explosions.”
Kirishima looked at him, taken by surprise. “Ah, right. I hadn’t thought about that. What material-“
“Who cares?! How do you do it, huh?” he interrupted, eager to get on with the actual thing. Okay, maybe a bit too eager. It was painfully obvious.
“Right, uhm, I normally watch porn?” he said, making it sound like a question.
Bakugo didn’t say anything and just reached over Kirishima, feeling him hold his breath, to grab his laptop, glove, and some lube.
He could literally feel Kirishima’s eyes digging holes into him. “What? I said I use a glove, so that’s necessary…”
“Ah, yes. Sorry.” Kirishima was blushing so hard his face was becoming the color of his hair. Bakugo felt like he was winning, trying to hold a smirk off his lips.
“Go on, search what you like,” he just said, once his computer lit up. Nothing else was said as Kirishima typed in a few key words and selected a video. He put the laptop on the floor in front of them and pressed play.
It was quite a long video, but Katsuki wasn’t interested. The blonde woman on the screen didn’t look appealing to him in the least. Neither did her male companion. This was exactly why he only masturbated when his body demanded it. He didn’t get how people could get turned on by it. Porn didn’t do anything to him.
But apparently it was working for Kirishima. Bakugo's eyes where inevitably drawn to him as the redhead started palming his erection through his sweatpants. His lips parted, but he held in a gasp. This awful quirk was sending more and more shivers that felt like electric charges down his spine and shortly after he started touching himself as well. The redhead seemed to be pretty big under his clothes. Bakugo found himself wanting to see it, shifting around in anticipation.
It didn’t take much longer before Kirishima slipped his hand underneath the waistband of his pants, grabbing his erection directly and started to jerk it slowly. Katsuki held his breath as he watched.
He had been right. Kirishima was big. Definitely bigger than him for sure.
It was his first time seeing anyone else’s. He never liked to shower with other people, only going to a public bath if there was no other option and always choosing to go either first or last to avoid the crowd. If he couldn’t help it he usually found a corner and didn’t bother to look at anything other than the wall. He had never been a people’s person.
Bakugo’s mouth was watering as he copied his friend’s movements. He could tell that Kirishima had more practice than he had on this matter because just mimicking his gestures he was feeling much better than he ever did alone. “Fuck…” he moaned. His hand was getting sweaty. He quickly put on his special glove and poured a generous amount of lube onto it. It was made with a metallic material covered in soft leather and with the aid of lube it felt pretty much like regular skin.
The noises coming from Kirishima were on the same level as the ones coming from the video. But a thousand times better because they were in real time, right there in his room. His eyes went back quickly to Kirishima’s dick and his hand moving rhythmically on it. He could see that Kirishima’s hair down there was dark, not the bright shade of red he had been expecting. The way he was panting and moaning lightly made his dick twitch excitedly in his hand.
From that angle he could see a small portion of Kirishima’s skin, right below his abs, where two lines formed a “v” shape that dragged the eye down directly to his crotch. He licked his lips, opening his mouth to pant, as he tried to think about how the redhead looked like without his shirt on, his eyes trailing upwards, to his collarbones peaking from his t-shirt and to his neck and then to his lips, reddened and wet.
He blushed deeply, realizing that he was not supposed to look at his friend like that. But it was just… Way hotter than anything that was happening in that video. Actually it might have been the hottest thing he ever seen in his life. He was for sure gonna treasure that image for another time.
He didn’t realize he had gotten closer to him until his nose brushed the hair at the back of Kirishima's neck. It smelled really good: a tinge of sweat mixed with faint sweetness and a purely clean smell overall. He couldn’t hold back another moan, this time way too close to Kirishima’s ear for him not to notice it.
“Ah, fuck… Bakugo…” Kirishima groaned, taking him by surprise. The redhead was not staring at the screen anymore. Kirishima's eyes were moving from his face to his dick, to his lips, the same way he had been looking at him, his gaze making him burn up all over. They both had their heads rested against the wall behind them, legs spread and thighs touching, looking at each other at just a couple inches of distance, their breaths merging into one.
Katsuki had to fight the urge to kiss him with all his might. As much as anyone could have argued that what they were doing would have ruined the friendship already, he strenuously held on to the excuse that it was just some fun between friends, nothing more.
But a kiss. A kiss would have destroyed everything.
Kirishima moaned loudly and Bakugo was dragged away from his thoughts. He looked incredible: with his hair more disheveled than usual, face red, lips parted and breathing hard, his hand moving frantically to get himself off. His body started shaking and when Bakugo looked back up into his eyes, that’s when he saw Kirishima reach his climax, closing his eyes for a few seconds.
That was…
“That was hot,” Kirishima chuckled breathlessly, cleaning his hand with a tissue. He fixed his pants quickly and looked down. “Damn, are you still going?”
Despite the tone of the redhead sounded impressed, Bakugo blushed deeply. “Just- Give me a few more minutes,” he growled. Or at least that’s how he intended to say it. It came out sounding more like a whine.
Kirishima didn’t say anything anymore and just kept his eyes on him as he was jerking off. The computer screen had turned off at some point and Bakugo just tried to concentrate on the feeling of his hand moving up and down the shaft, a bit roughly, but teasing the head just how he liked. Kirishima’s eyes on him accentuated that hot pooling in his gut that was so clearly a sign that he was close to release.
And yet.
Minutes passed, moans turned into whimpers, legs shaking… And Katsuki still wasn’t coming.
Suddenly the feeling that something was wrong hit him like a train.
He couldn’t cum.
His hand stopped and his eyes started stinging with tears of frustration.
“Bakugo? What’s wrong?” Kirishima noticed immediately and sat up, worry clear in his voice.
“I can’t…” he whined, panicked. “I can’t finish.”
Kirishima sat up, afterglow post orgasm instantly gone. “Don’t panic,” he said, sounding panicked. “Maybe it’s because I’m here?”
“No, that’s not it,” Bakugo shook his head. If anything it was because of him that he was so close. “What if it’s that quirk? And I just can’t because I am cursed like that? So what if what we did only made it worse?!”
Kirishima nodded, looking concerned. “That would definitely be a problem. But it’s also only the worst case scenario. Let’s try more first. Here, let me help you, maybe you are just tired…”
Before Bakugo could stop him, Kirishima had moved his hand to grab Bakugo’s length. Instantly a wave of white heat hit him in the gut and left him breathless. “Oh shit, fuck…” he cursed as he grabbed onto Kirishima to stop his body from convulsing.
Kirishima’s hand tightened around his shaft and started moving progressively faster. “W-wait, Kiri-… No, stop, I’m- Ahh”
His hands grasped at Kirishima’s arms and - before he could control himself - explosions started from his left hand, the other one still contained by the glove. His vision became completely white as he had probably the best orgasm he ever experienced in his life, finishing in Kirishima’s hand. And the best part of all of that was that the redhead didn’t get caught off guard and didn’t stop stimulating him: he made him ride the entire wave of pleasure, milking every last drop of cum out of him.
The spasm that ran through his whole body left him drained and tired. His head felt light and blank as it never had before as he let himself slide down until he was lying on the bed.
He was still breathing hard, sweaty and sensitive all over.
That felt incredible.
“Hot.” Kirishima’s voice had an interesting edge to it. His eyes opened slowly, but all he could give him was a side eyed look, without being able to sit up or even move. Kirishima had an odd look on his face, half way between embarrassment and something else.
“What?” his voice sounded so rough and spaced out it was quite shameful.
The redhead shifted in place, still sitting between Bakugo’s legs. He had been so kind to pull his pants back up. “Well, I mean… I know it was just the quirk, but anyone seeing that would have thought the same, you know. You… You looked really good,” he mumbled, his face still completely red and his hands placed in a way to cover his front.
“Oh?” That was definitely new. “Hey, shitty hair,” he smirked, trying to use a mocking tone. “Did you just get a boner from seeing me come?”
Kirishima’s eyes became so wide he was concerned for a second they were gonna fall off his head. He started opening and closing his mouth like a fish, trying to say something, but failing miserably.
Bakugo was not expecting that reaction. He gathered all his strength to push himself up to lay on his elbows, patiently waiting for him to gather his thoughts.
“So what if I did?!” He blurted out finally, his ears turning completely red. “It’s the first time I see anything like that. Like, in porn it’s not the same and it’s also the first time I see a guy… A-and you are just so manly it’s a very big gap compared to when you… I mean it’s just really, uhm, sexy.” Kirishima was avoiding to look at him, clutching the front of his t-shirt, fidgeting.
Katsuki was left completely speechless. He didn’t know how he was supposed to feel at this sudden confession. How would have another guy reacted to it? What was currently going through his head right now was probably different from anything most people would have thought.
He saw an opportunity. A really good one at that.
It was undeniable that what just went down felt unbelievably good. Hell, he wanted to do it again, there was no hiding that. And right now, looking at Kirishima in front of him, sporting a tent and completely flustered because of him, Bakugo couldn’t help but consider that option. He didn’t mind the idea of just having to return the favor if he could get to have another orgasm like that.
He sat up. “Kirishima,” he called, startling his friend. “Go wash your hands. It’s disgusting.”
The look in those red eyes was as if he had just kicked a puppy. “Yeah, you are right.” Never a laugh sounded more forced. Kirishima stood up and walked sadly to the bathroom.
Bakugo sighed. “And come back here quickly,” he added, before his friend could close the door. He could feel Kirishima’s eyes digging holes into his head as he averted his own, a little nervous for what he was about to suggest. He could only hope that he was reading Kirishima’s reactions right. If he was wrong he could always play it off as a joke, but still…
That minute felt like an eternity. He started playing with the hem of his sweatpants around his ankle, sitting on the bed with one leg folded and the other hanging over the edge.
When Kirishima came back and sat on the bed he didn’t look up. They were sitting in silence, so thick it could be cut with a knife.
“We could do it again,” Bakugo finally started. He shot a glance to Kirishima, finding him very much interested and looking like he wanted to hear more. He cleared his throat before continuing. “I mean, we could… help each other. It’s just convenient, isn’t it? Especially since it seems I can’t do it on my own because of this stupid quirk.”
“Yes, absolutely,” Kirishima replied maybe a bit too fast. Eager much? “We are both guys, it’s not even weird. And you are my buddy, I totally want to help you!”
Bakugo grimaced at being called like that, but he guessed he couldn’t complain: he got the outcome he was hoping for. “Okay, so…” He didn’t really know what else to do but simply get on with it and pull down his pants. He wasn’t fully hard yet, but Kirishima’s hot stare was already making him feel something. “What are you waiting for?!” he blurted out, embarrassed from being stared at.
Kirishima stumbled to move, but all the awkwardness in his movements was outshined by the entrance on scene of his full-fledged erection. For fuck’s sake. It was huge. Seeing it this close it made an even bigger impression. Bakugo wasn’t small himself, but Kirishima definitely had a solid inch on him.
“Damn,” he said, trying to play it off with a teasing smirk. “Someone’s excited. By the way, how come the carpet doesn't match the drapes?”
“Oh, uhm…” Kirishima blushed. “I actually dye my hair.”
Katsuki hummed and nodded understandingly. “I never knew,” he commented, reaching his hand out to pull lightly at the curly hair around the base of Kirishima’s dick. It was completely black and despite the difference it didn’t look bad at all.
“Bakugo…” Kirishima whined, his cock twitching in anticipation of being touched again.
As much as he would have liked to bully him, he was also eager to get on with it himself. His gloved hand caressed the underside of Kirishima’s dick, making him shiver visibly. “You too,” he said, as he made his fingers slide up the shaft, teasing the tip.
“If you promise not to come as soon as I touch you…” Kirishima pushed himself closer to him.
“You fucker-” His insult was cut short in his throat by Kirishima’s warm hand wrapping around his dick.
“Just kidding. It was very flattering when you did that,” he whispered, resting his forehead on Bakugo’s shoulder. “It made me happy that I could make you feel good.”
They were so close now. Their thighs were pretty much one on top of the other. Bakugo could feel Kirishima’s breath on his neck and collarbones, with every hitch and exhale as he started to pick up the pace in his handjob.
He was right: this was so hot. Especially so because it was directly his fault that Kirishima was feeling good. It was an inebriating feeling.
And at the same time the pleasure he was getting in return was unmatched. It was simply the best. He was definitely gonna get the prize for best idea of the year. Hell, the decade even.
Soon his head started turning into mush, his thoughts overshadowed by pure bliss and nothing else. He covered his mouth with his left hand when his moans started to get out of control and biting his lips wasn’t working anymore.
He was moving his hand on Kirishima’s cock as if it was his own, chasing the release that was getting closer and closer. Kirishima matched his every movement, their minds clearly on the same track.
“Bakugo, oh god…” Kirishima mumbled, hiding his face in the crook of Bakugo’s neck. “You smell so good… Fuck. Don’t stop. I’m gonna come”
“M-me too…” he managed to say, between muffled moans and curses. His palm started to sparkle and he almost burned his mouth.
“Put your hand on me,” Kirishima said, grabbing his wrist and pulling it away from his face. “I can take it.” His arm was already hardened.
Bakugo didn’t wait for him to repeat it another time. He grabbed Kirishima’s bicep with his left hand and picked up the pace with his right, explosions going off on both.
It was just a few moments before Kirishima was shuddering and coming all over his glove. Just feeling that was enough to send him over the edge, too.
But this time he didn’t get completely distracted: he kept his hand moving, copying Kirishima, making him ride his orgasm as much as he was doing right back to him.
Once it was over they didn’t move, forehead resting on top of each other’s shoulder, trying to catch their breath.
“Wow…” Kirishima chuckled finally. “The explosions make it feel like your hand is vibrating. It’s amazing.”
Bakugo raised his head to look at Kirishima: he looked completely sated now, his arm back to normal and without a scratch, and his hand dirty with Bakugo’s semen. It wasn’t a bad view.
“Huh, is that so?” he said, pushing Kirishima away to stand up. “Then I guess you should come back for more, then.” He turned around so that Kirishima couldn’t see him blush as he said that and just locked himself in the bathroom. Openly admitting he still wanted to do more things like this would have been way too embarrassing, so putting the blame on Kirishima was the best solution for his pride.
But clearly Kirishima didn’t see it like that. “I definitely will!” he yelled excitedly from the other side of the door, not a trace of shame.
As Bakugo turned on the faucet, he couldn’t stop a complacent smile from forming on his lips.
