Work Text:
Izuku wasn't really up to hanging out tonight, but all the guys were going to be there, so he agreed to go. He'd rather go home and rub one out, since he'd been too busy lately to do so. But of course on his one day off the guys begged him to hang out. He hadn't seen most of them in a while, so he agreed.
He was beginning to regret coming though when he heard the conversation in the living room as soon as he walked in. Kacchan always left his door unlocked, something Izuku hated, but Kacchan just dared someone to break in.
"You're gonna look at this bitch and tell me she's a top? This is the definition of a pillow princess!" Denki exclaimed, shoving his phone in Sero's face. He could see there was a picture of Ochako on it.
"No way, dude!" Sero yelled back at him.
"Um... What're you guys talking about?" Izuku hesitantly asked as he plopped onto the floor between to Kirishima and Todoroki.
"They're deciding who would be the top and bottom in a gay relationship" Kiri answered with a chuckle, handing Izuku a beer.
"I don't get it" Todoroki mumbled
"It's a bit inappropriate" Iida muttered into his glass. Izuku was sure Iida regretted coming more than Izuku ever could.
"You're just mad you were voted a bottom" Kaminari said. Iida just blushed and looked away. "Kiri, I've had this question for years"
"Oh fuck" Kirishima muttered, sending an sos look at Izuku, who just chuckled at him.
"So when you use your quirk and get hard, do you also... Get hard?"
"Have you no shame at all?" Iida muttered and Kirishima laughed hard before answering. Izuku couldn't help it, he kinda zoned out after that. He heard bits and pieces of the conversation, but he mostly just stared at the can on the table in front of him, unseeing and unthinking. Work really kicked his ass this week.
"With a tongue like that? She's definitely a top!"
.
"She's so shy, I just can't see her being a top"
"I happen to know for a fact that Jiro is a proud switch"
.
"Shut up, Kaminari, you're too lazy to do anything but lay back and take it"
.
"Oh I know you could make whatever you wanted on the end of those tentacles"
"I'm not acknowledging that"
.
"She would have to be the top! Nobody would be able to see what they're doing!"
.
"Ugh why even bring him up? Bakugo is the most obvious top I've ever met"
When Izuku heard that, he couldn't help but to snort out a laugh. Then he noticed everyone was looking at him.
"What?" He asked, confused. Had somebody asked him a question and he didn't realize?
Kacchan leaned forward, towards him.
"You think that's funny?" He asked, a typical scowl on his face.
Oh he was talking about that? Surely it was a joke, right? Kacchan? A top?
"...Well yeah. I mean I just can't imagine you being a top... But maybe that's just me" Izuku knew he was poking the bear, but he knew Kacchan well and knew where to draw the line. Well he normally did. He'd been so horny lately though he wasn't certain there was a line.
"Ha! You think you could top me? I bet you wouldn't even know what to do!" He sat back again, laughing. The other guys awkwardly laughed as well. They all expected the conversation to move on, but...
"Wanna bet?" Izuku asked, still looking at Kacchan. Said man simply stared hard at him, like he thought his eyes had lasers if he stared hard enough. Izuku on the other hand, slowly looked his childhood friend up and down before licking his lip "Cause I bet I'd top you so hard it'd ruin you from anyone else" Izuku drawled out, grinning at how Kacchan's cheeks started to redden.
This time it was Kaminari who snorted, unable to hold it in any longer. None of them had heard Izuku like this before and it was fantastic. They all just looked back and forth between the two men, waiting for one of them to give.
Just when it looked like Bakugo was going to explode, Izuku winked. He shot up out of his seat, leaning forward to grab Izuku.
"Let's go, fucker" He muttered, attempting to sound tough, but still red all the way down his neck. Izuku just smiled and followed behind him.
Bakugo threw open his bedroom door and shoved Izuku inside. As he shut the door, he planned on saying something to try and scare Izuku out of it, but before he could think of something to say, he was slammed into by a wall of muscle.
Izuku pinned him to the door with his hips before grabbing his hands and forcing them up over his head. He slowly ran his tongue up the side of his neck, stopping just before he reached his mouth
"You sure about this, Kacchan?" He nearly growled into his ear. Fuck it was the hottest thing he'd ever heard.
Of course he wasn't sure. He'd only just recently accepted to himself that the feelings he felt towards the nerd were anything positive. Now he was hard as a rock and they hadn't even kissed yet. But what the nerd bet... He had to know what he planned on doing to win.
"Y-yes" fuck he was already reduced to a stuttering bitch but he could accept that as Deku mouth pressed against his in the best kiss of his entire life. As he kissed him, he also ground their hips together, causing his jeans to rub very uncomfortably against his dick.
Without him even noticing, Deku managed to hold both of his hands up with only one of his own, and the other was up his shirt, feeling up his pecs gently before suddenly squeezing a nipple.
He couldn't moan. He couldn't make any noise that made it sound like he liked it, but he couldn't control the way his knees buckled.
Deku finally pulled away, but their mouths stayed connected by a string of saliva. That kind of thing would normally gross Katsuki out, but with Deku? It was so sexy.
"Get on the bed" Deku demanded, with a growl still in his voice.
"Tch" Katsuki responded, trying to seem annoyed at being bossed around but honestly right now Deku could tell him to dress in drag and do a hula and he would.
He tried to even his breathing as he approached the bed, but then he heard a... almost a sigh from behind him. He turned and saw Deku, still standing by the door.
"Man, you like to complain that I'm slow" He said, sounding like normal, with the sexy growl missing from his voice "Kacchan... We don't have to do this if you don't want to"
Bakugo had no idea what to say. Leave it to shitty Deku to go and.... Be himself at a time like this. He closed his eyes for a second and prayed to anyone who would listen to give him strength.
"Deku. Come here" He said in a voice that didn't sound his own. It was far too gentle, but that's what the damn nerd did to him. Deku hesitantly walked closer to him, stopping a couple feet away "You know me better than anybody. When the fuck have I ever done something I didn't want to do?"
"I know, but I don't want you to do this just because you don't want to lose some fucking bet" he sounded frustrated now, which was actually also kind of hot. The dork had the patience of a saint and didn't often get frustrated.
He didn't want to admit that, in his eyes at least, he'd definitely already lost the bet so it didn't matter.
"Izuku... I want this... I want you" He decided to say. And holy shit that look returned in Deku's eyes. That look that said he wanted to destroy him and he felt a shutter run through his body.
Deku closed the space between them and shoved him back onto the bed. Katsuki watched as Deku pulled his shirt off and undid his jeans before crawling up and between his legs until he reached his face, where he kissed him again, more gently this time.
"Shirt off" He growled again and Katsuki had to fight the urge to just rip his shirt in half.
Instead he took it off like normal and threw it across the room. By that time, though, Deku had moved back down and was unbuttoning his jeans.
Of course Izuku wouldn't say so, but he was also fighting the urge to just rip them off. Which wasn't made easier when he pulled down the zipper and noticed-
"You're not wearing any underwear?" Izuku's voice was almost a snarl which, combined with his cock being half out, finally forced a sound out of Katsuki. The whine only got louder when Izuku yanked his jeans hard, pulling them off completely in one swoop "If I'd known that, we could have been doing this sooner"
Before Katsuki could think about what was happening, Izuku had his tongue on his ass, licking a slow strip from his hole to his balls and fuck it felt good.
"Shit!" He couldn't help the shout that escaped him. Sure he'd had a blowjob before, but he'd never had someone's mouth... There before.
Izuku's hands gripped his hips, keeping him pinned to the bed as his tongue continued to massage, lick, and prod him. He tried his best to keep some of his dignity intact and not whine and moan like a little bitch, but... His resolve was pretty quickly demolished.
He was so wet, stretched, and relaxed from Izuku's tongue that he almost didn't notice the finger slip inside him. He bucked hard, but damn Deku was so strong he wasn't able to move an inch.
He was going to have some gnarly bruises on his hips and, although he'd never admit it, he couldn't wait to see them.
One finger quickly became two, and then three. Katsuki didn't know how much more of this he could take. Deku purposely kept avoiding his prostate, only slightly grazing it a few times, just to hear him whine. He knew because the bastard had the audacity to chuckle after the third time.
"You ready for me, Kacchan?" Izuku finally asked after what felt like an endless torture of fingering.
"Yes! Yes, get on with it!" Katsuki was only a little embarrassed by how quickly he responded.
"Hmm that's not how you ask for things, Kacchan" His fingers stopped moving before he pulled when out completely. Katsuki immediately felt a panic.
"Please!" He quickly wrapped his legs around Izuku, trying to keep him close. "Please, please, please"
He was sure he blushed so hard his skin was going to melt off when Izuku kissed the tears away that somehow managed to escape. He'd never been so desperate for anything in his entire life.
"I'm not going anywhere, Princess, now use your words. Please what?" Izuku asked, his voice deep and soothing.
"I need you. Now. P-please fuck me" Another tear slipped out, but Katsuki would find time to be embarrassed about it later because Deku was kissing him again, deep and gentle.
"Since you asked so nicely" Their lips were still against each other when he spoke, and that was the only warning Katsuki got before Izuku was pushing inside.
Katsuki screamed. He couldn't help it. Way in the back if his mind he knew he was going to be teased for it for the rest of his life, but it was worth it.
"H-harder. Please" Katsuki pleaded when Izuku tried to take it slow. When he saw the smirk he got in return, he knew he was in trouble. Izuku pounded into him so hard get could see the green sparks of his quirk activated.
Neither of them could last long at this pace.
"Zu, I-I'm gonna-"
"Don't you dare cum yet, Princess" Izuku growled.
Katsuki didn't have to worry too long about holding out, as just a moment later Izuku was to the hilt deep inside him, filling him with cum. That feeling alone sent Katsuki over the edge and he painted his abs with cum as his vision blacked out.
When he came to, he saw Izuku's perfectly bare ass walking towards the bathroom. He came back with a wet rag, and didn't say anything before gently wiping him down.
They were both pulling their clothes back on before they finally made eye contact.
"So... Did I win?" Izuku asked, smirking.
"Oh fuck you, you know you did" Kacchan gave a rare real smile as he shoved Izuku over.
When they left the bedroom, most of the guys in the living room had left. The only ones left were Denki, Kirishima, and Sero.
They all turned to them as they entered the room, all flushed pink, but with big shit eating grins on their faces.
"....Bump it, bro" Denki finally said, giggling as he held out a fist.
