CW: NSFW

I'm laying in bed thinking about Kirishima getting a Ground Zero daki in their 3rd year as a joke from Kami. And he's shocked and a little embarrassed but almost actually dies when Bakugou walks in and sees it.

The blond’s eyes blow wide and he turns bright red, before marching over and snatching it right off him and storming off with, “don't be a fucking pervert what the hell? Why does this exist?” As he rounds the corner away from them.

Kaminari obviously bursts out laughing at both of their expenses and pats Kiri on the shoulder, “Awh man, better luck next time! I'll give you the website and you can order another with discreet packaging.”

“I never said I wanted one! Oh my god I can never ask him out now, he thinks I was gonna hump the thing! Why’d you gotta sabotage me like that man?” He's still blushing as he makes his way into the kitchen to splash his face with cold water and think about his choice of friends.

He finally managed to get over his embarrassment and almost forget about the incident that shall never be spoken of again.

Even if he does peep the website and add a double sided GZ daki to the basket.

He removed and re-added it maybe twenty times, repeatedly staring at the daki Bakugou's dick in the reverse image, +

before groaning and shoving his hand into his shorts as he bit his lip and fisted himself like a man possessed until came all over himself and collapsed back against his bed to enjoy his afterglow before the guilt set in.

He saved the page but didn't order the demon daki of sexual frustration before he finally moved to clean himself up and change his clothes because he hadn't had enough blood in his brain to even think about grabbing tissues.

It was cool, he could live without it, he told himself repeatedly over the next couple of weeks. He didn't /need/ to hump a pillow with his naked best friend on to get off, it was totally fine.

Kirishima wasn't sure how long he could resist the thing, but he was a manly proud man and he'd put it off for as long as damned possible.

Well, until one evening he walked into Bakugou's room without knocking. The blond had been playing music a little on the loud side like he usually did when he was working out extra hard, and Kirishima wanted to maybe catch a peek at his best friend soaked with sweat and panting.

Never in his wildest dreams would he have ever imagined he’d see what he was currently staring at, jaw dropped as his dick hardened so fast it made him a little dizzy.

Bakugou /was/ soaked with sweat and panting, but he wasn't working out. His back faced the open door as he slammed himself down unevenly onto a strap mounted on the daki with his own image on. The cock sliding in and out of him was bright orange and shiny with lube.

He was almost desperately fucking into a fleshlight in a metal case as his hands smoked.

He threw his head back a moment later with a cry of, “/fuck/!” And stilled as he moaned, loud and long and full of relief, before collapsing forward and breathing raggedy against the image of his own face.

“Holy shit…” Kirishima stood frozen on the spot, mouth still hanging open with an embarrassingly large wet patch in his boxers from how close he was to coming completely untouched.

Bakugou tensed and bolted upright, eyes wide as they locked on Eijirou and his cheeks exploding with colour.

As he turned he automatically pulled the fleshlight off his cock and come practically poured from the toy to soak his softening cock and run down onto the abs of his daki self. He flushed darker and grabbed for the pillow at the head of his bed to cover himself.

“What the hell pervy-shima?! Don't you know how to /knock/?? How long have you been standing there?! Close the damned door before someone sees!”

“I wasn't perving, it was an accident! And I'm not the pervert here Bakugou what the-?!” Kiri couldn't even form a coherent thought in the aftermath of seeing the hottest thing he might ever witness in his entire life.

“It's my room and my body pillow. I'll do what I want! /You're/ the one that's hard right now!”

“WHO WOULDN’T BE?! I can't help it that you're so hot and I wanna kiss you!” Eijirou burst out as he waved his hands, before freezing as he realised what he'd just said. He flushed and tried to back up but Bakugou's eyes had already bugged out.

“Wait, you actually like me?? I thought you were just being a weirdo with this pillow! Or like trying to embarrass me. And close the door!” Kiri made to leave but Bakugou called him back, “with you on /this/ side you absolute dipshit!”

Eijirou blushed harder and stepped into the room, finally closing it behind him as he tried to look everywhere but at his naked best friend who he was pretty sure was still sitting on a fake cock mounted on his own pillow crotch.

“You gonna do anything about that?” Bakugou pointed straight at the very noticeable outline of his boner and raised an eyebrow.

“Well I mean, I was maybe…gonna, yeah. But uhh…” he looked away and scratched st the back of his head, beyond embarrassed but too worried that if he rearranged him his hand would come out absolutely soaked with pre come.

Or worse, he'd accidentally make himself come and have to move country just to avoid looking at the blond ever again.

But Bakugou rolled his eyes, “come here.”

“Why?” Eijirou half panicked even as he did as he was told, biting his lip and ready to harden in case his best friend blasted him for watching him fuck himself silly.

“I'll do it for you, if you want…” his cheeks tinted a little pink and he scowled up at him like he was half daring Kiri to reject him.

“Holy shit s-seriously??” Eijirou groaned and nodded like he was trying to fling his own head from his shoulders as he bit his bottom lip and sneakily pinched himself to see if he was actually dreaming.

“Yeah seriously. I can't really use my hands, but I can use my mouth…or this.” Bakugou lifted the fleshlight he'd just come inside.

“Fleshlight, fleshlight. If you put your mouth on me I'll come straight away and I don't need to embarrass myself anymore today.” Eijirou said sheepishly and Bakugou snorted a short laugh and rolled his eyes.

“Whatever you say, lemme go wash this thing. Throw me a towel, I'm kind of a mess. I was gonna go again but you decided to walk in and give me a fucking heart attack instead.”

“No, don't wash it! It's totally fine!” Wow he really needed to shut his big dumb mouth before the blond thew him out on his ass.

“Wow. You're a bigger pervert than I thought. Come here.” Katsuki laughed, pulled him forward by the wrist and shifted back a little on the body pillow, before half whining as he bit his lip and closed his eyes for a moment.

“Are you actually still sitting on that strap on? Oh my God I think this is the best day of my life.”

“It ain't a bad day for me either, now get naked, I wanna see your dick.”

Eijirou had never taken his clothes off faster in his life, and within moments he was being pulled onto the bed to kneel opposite Bakugou on daki Ground Zero’s face as the bond leaned in to connect their lips.

Eijirou gasped and sank into the kiss immediately, moaning when he felt hot fingers skim over his length and down to palm his balls for a moment, before pulling away.

His eyes flew open as he felt the come and lube soaked fleshlight slide over the head of his cock and down to sheath him, still warm from use. He choked almost helplessly into Bakugou's mouth and grabbed his bicep to steady himself.

Holy fuck his cock was covered in Bakugou's come!

He might not be able to last as long as he was hoping to, shit.

He moaned again when the blond did something to the toy and the pressure inside changed, like it was sucking him for a second before releasing.

He pulled back with a gasped out,“can I touch you too? Please let me touch you, /shit/.” He bit his lip to try to stifle a whimper when the toy slid up and down his cock a little faster and twisted as Bakugou nodded and shifted on the daki a little.

“Fuck yeah you can touch me.”

Eijirou wasted no time as he snatched up the pillow that covered his best friend's modesty and wrapped a hand around his come covered cock. He tossed the pillow behind himself near the head of the bed, squeezing and palming the blond's length before stroking up and down slowly.

“Nghh /fuck/ your hand feels so good. Shit, fuck…” curses muffled against his shoulder as Bakugou dropped forward immediately to groan against his skin, “god Eijirou, I'm… don't tease me I've never had a hand job before. Faster, please faster-”

Eijirou was more than happy to oblige and the blond hissed in a sharp breath and bit down as he began rocking his hips on the strap inside him and the scent of sweet burning filled the air.

This was the hottest thing he'd ever experienced and Eijirou could already feel imminent release building in his gut as Bakugou jerked the fleshlight around him a little faster as his movements became uneven and more desperate.

He tried to hold off at least a little longer, but Eijirou knew he was a goner as soon Bakugou moaned right into his ear and bit the shell, before almost possessively sinking his teeth into the side of his neck.

“Katsuki I'm gonna come, oh my god-” he warned breathlessly. He started to tell him to slow down but the blond just pumped him even faster, like he was trying to force the come right out of him.

“I'm gonna make you come so fucking hard.” Katsuki growled and kissed him messily, panting into his mouth as he chased his own release, shamelessly thrusting up into his slippery hand like he did his stroker.

And he did.

Eijirou tensed, mouth falling open uselessly as he cried out and gasped his release into Katsuki's mouth, filling the toy working him with ropes of seemingly endless come to mingle with his best friend's.

His brain tapped out for a few seconds as pleasure blew through him so intensely he was sure it might have actually changed him as a person, until he felt a sweat dampened forehead thud back against his collar bone and heard Katsuki cursing up a storm against his skin.

“So hot, so fucking hot, I'm-” he pulled the toy off his cock and tossed it aside, bouncing faster and clearly uncaring of the come that ran from it all down Eijirou's cock to soil the daki Bakugou's face.

“I’m- shit, I think I'm gonna explode-” he moved his hands away from their bodies quickly and groaned helplessly against Eijirou's neck as more smoke curled from his palms and tiny crackles started popping along his skin.

“It's okay, you can put them on me, I'll harden.” He assured immediately, twisting his wrist as he fisted the cock in his hand faster and smoothing his palm over the weeping tip. It might even help muffle the blast if the blond really did lose control of his quirk for a second.

“/Back/, harden your back, I'm gonna-” he cut off as his hips stuttered for a moment, before smoking hands wrapped around Eijirou's back and +

Katsuki began fucking up into his hand so viciously it was like he was a mating animal as he began simply chanting, “/faster, faster, faster/!” Until he choked on a moan and teeth sank into Kiri’s probably already bruised neck again as an explosion sounded.

He felt come soak his hand and splatter against his abs, chest and cock as Katsuki rode out his orgasm before collapsing into him, +

suddenly dead weight that pushed them back to flop against the pillow at the head of the bed, covered with and laying right in the mess of their own making.

The blast wasn't as loud or big as Eijirou had been expecting after watching the blond fight, but most of the dorm had probably heard it. It was /still/ literally a small bomb going off.

But he honestly didn't care right that minute as Katsuki panted against his chest for a long moment before finally sliding off of his well fucked strap.

He awkwardly shifted to move the daki from beneath them and kick it to the floor uncaringly before flopping back down beside Eijirou.

He made a sound of disgust and sat up quickly, looking at the large puddle of come he'd just lay in from the fleshlight, before glaring at the toy in question and grabbing it to toss to the floor too.

He looked at the wet patch for a few seconds before shrugging and throwing himself back down face first with a huff.

“Stop throwing things covered in jizz around, oh my god.” Eijirou exclaimed. As if the blond had just lay back down in a load of come without caring. “Are you okay?” He asked, shifting to lay on his side and rub His best friend's back a little as Katsuki’s back heaved.

“‘M cool. I just need a minute. I've never come that hard in my life, my bones feel like goddamn jelly. Thank you, just fucking thank you Eijirou. Jesus Christ. Sorry I almost blew us up.”

He spoke brokenly into the pillow before rolling heavily to his side to face him, “I think I got come on this pillow too, gross." He wrinkled his nose and wiped the back of his hand over his cheek.

Eijirou burst out laughing, “oh yeah it's totally /everywhere/ man. I'll help you change the sheets in a sec if you want though. I mean I helped make a mess of them, it's only fair.”

Katsuki snorted and rolled his eyes, “I mean, yeah. I don't regularly get come all over everything, I jerk off with a literal jizz catcher. You just scared the shit outta me walking in like this is your damn room, dumbass.”

Eijirou blushed, “sorry, I'll knock from now on.”

“Why? Now if you catch me jerking it you can just come in and help.

“Holy shit, really?!” Kiri sat bolt upright and threw himself at the blond to hug him.

“How dumb are you? Do you really think I'd find out you liked me, jerk you off and literally almost blast us to hell coming into your hand if I didn't like you too? What planet are you from?”

“You wanna maybe go out with me then? You know, as boyfriends?” Eijirou bit his lip, hoping he wasn't pushing his luck. “And I don't hear any explosions from in here unless you're punching stuff and yelling, do you not jerk off much…?” he trailed off.

“Yes dipshit, I'll go out with you. I thought that was pretty obvious, I'm laying in a pool of your come. And I've only lost control of my quirk once that bad and that was just now. +

+ My hands usually just smoke and get hot and sometimes crackle, but it ain't safe to put on my dick, that's for damned sure.”

Katsuki sat up and cracked his neck a couple of times and half straddled Eijirou to climb from the bed and flip the daki, grimacing at the state of it.

He pulled the strap off it and picked up his fleshlight, sliding the slightly sooty metal casing off it, before taking the toys into the en suite toilet to throw them in the sink.

He came back a moment later and stripped the cover off the body pillow and tossed it straight in the washing basket, before crossing to his closet and taking out another long pillow case.

Wait a minute...

“Is that ME?!” Eijirou burst out as he shot from the bed to gape at an image of his own shark toothed grin and his bare abs.

“Yeah, look.” Katsuki turned it around and Eijirou flushed as the naked version of him gave him sultry bedroom eyes, “your dicks bigger than they drew it, but they got mine wrong too, I don't give a fuck. +

+ That orange strap? I made by casting my own dick with one of those kits 'cause I couldn't find one I liked.” He shrugged as Kiri tried to process the information and his eyes bugged out.

“Wait… wait you saw the naked one of you too? Shit did you buy it? Can I see? And you cast your own dick? You were riding your own… I'm…”

/In fucking love/.

“I /own/ the naked version of me too, it's hot okay? Fucking sue me. I checked the label on the other one and found the website so I ordered the ones of us. +

+ I had to hump pillows to get off for /years/ before I got that reinforced quirk-light for fire and explosion types. And that thing is basically life sized, there was no way I wasn't gonna use it.”

“You took that thing off me and called me a pervert and then took it back to your room and humped it yourself? And /I'm/ the pervert?” Eijirou laughed as Katsuki punched him straight in the arm and blushed.

“Shut up, jerk. And put some clothes on, I think we really need to go shower before this /mess/ dries completely.” Katsuki gestured between them before slipping the Red Riot case on the pillow.

He left it on the floor as they stripped the bed and dressed, leaving the actual changing of the sheets for when they were clean.

As they walked into the common room they were greeted with the sight of Shoji, Iida and Kaminari sat on the sofas.

Kaminari shot to his feet, “GUYS? SERIOUSLY?! I mean congratulations but Jesus Christ!” He shook his hands, eyes wide with both shock and frustration. Iida was bright red and Shoji was pointedly looking away.

Both his and Katsuki's faces burst into flames and Eijirou kind of wanted the ground to swallow him. He hadn't really realised how loud they'd been. Well except obviously the whole huge explosion thing. And maybe some of the shouting and screaming…and the bed rocking.

Ah, shit.

Katsuki recovered first and flipped them all off, baring his teeth, “oh fucking eat me Dunce Face.” His cheeks were still bright red but he straightened his back and marched forward to head to the showers.

“It sounded more like you were trying to eat /each other/! What's that on your face?” Kaminari’s eyes widened as Katsuki slapped a hand to his cheek and blushed harder, stalking straight from the room.

“I'm gonna just…” Eijirou followed immediately, having absolutely no idea what to say.

He burst into the bathroom and threw back his head, “/how/ did I not see you still had come on your face?!” They stared at each other for a long moment, before simply bursting out laughing.

“Maybe we were a bit loud.”

“Dude you detonated like a /grenade/. We're gonna have to maybe try and work on that. You know, with /lots/ of practice. If you want?”

Katsuki snorted and yanked his shirt over his head, tossed it onto the bench behind them and kicked off his house slippers, “if you touch me I'm probably gonna go off, like, every fucking time I think. That was incredible and it was just your damn hand.”

“Flattery will get you absolutely /everywhere/ Katsuki. Wanna try my mouth next?” Eijirou grinned as he leaned down and kissed the blond.

Katsuki groaned as he pulled back, “I don't even know if I can get hard again but fuck yeah. I can practice not blowing us all to hell while you practice blowing /me/.”

His grin was excited as he shoved down his sweatpants and kicked them away before stalking straight into the nearest shower, “hurry up, I want my first dick sucking from my boyfriend.”

Eijirou snorted a laugh and followed. He'd never sucked a dick before, but he had a sneaking suspicion his boyfriend was gonna blow half the bathroom sky high.
