Izuku wasn’t sure why he kept staring.
By all rights, he should have wanted nothing to do with the guy. He’d come in on their first day acting cocky as hell, reminding everyone who would listen that he had gotten the highest score on their entrance exam, and trash-talking them all about how he was going to beat all their asses every day up to and after graduation, to become the number one hero. He’d talked shit about Izuku’s lack of control over his quirk, he’d made fun of anyone who got a question wrong in class, he was just an all-around unlikeable dude who Izuku wanted nothing to do with.
Unfortunately, he was also hot.
Right through their years of high school, Izuku had avoided him as much as possible. He’d sat behind him in class, so he saw every increase in bulk or definition that he’d quickly managed under their new training regime, but they’d never really spoken to each other, unless class requirements dictated it. Somehow, they’d both managed to make their own little tight-knit groups of friends – Izuku had gotten close with Ochako, Tenya, Tsuyu and Shouto, the best friends he could ever have asked for, while Bakugou had been dragged into the orbit of Kirishima, Kaminari, Sero, and Ashido – he wasn’t sure how considering they were some of the nicest people Izuku had ever met, but apparently there was something about Bakugou that they found endearing, or entertaining, or something.
He really didn’t understand.
He and Ashido had seemed to be... especially close, as they’d gotten close to graduation. She’d held his arm as they’d walked between classes, the two of them had regularly disappeared together for dinner, and when they were all hanging around in the common room, she’d usually had her feet kicked up in his lap, or her head on his shoulder, or something. Izuku wasn’t sure if it was official and he’d missed an announcement, or if they were just... hanging out? Izuku wasn’t exactly a dating expert, he’d been a real loner growing up, so he didn’t know what the right words were.
Right up until graduation, Izuku had managed to keep their lives separate. They’d had no real reason to cross, beyond the occasional nod or ‘good morning’ in class, and Izuku had been happy with that.
Then they’d been hired at the same agency.
He hadn’t even realised which way he’d been looking, he’d just been turning away from his gym bag to check if he’d missed anything, but his eyes had caught that little glint of light, reflecting off something, and from that moment his brain had been fried. Because on Bakugou’s chest, which was already insanely muscular and defined and excellent to look at even without any help, there was a piercing. A tiny silver bar, running straight through his nipple, that no one else even seemed to look twice at.
How long had he had the thing? Had everyone else noticed it already? Had he already had it when they’d met? Was Izuku the only one who hadn’t been perving at his classmates from day one, to know for sure? That wouldn’t have surprised him, honestly – his classmates hadn’t exactly seemed averse to hooking up in their bedrooms, they’d all just pretended to be oblivious to the very clear noises that came through the paper thin walls. There had been a lot of rush orders for noise-cancelling headphones to be delivered, throughout their time in the dorms.
But Bakugou. Bakugou. Of all people, Bakugou had gone down to a studio, had signed a form saying ‘yeah, stick a needle in me’, and had put jewellery in his body, just for the hell of it?
Had it been his idea? Or Ashido’s? Had she suggested it? Gone with him? Held his hand while he’d gotten it?
Bakugou’s eyes darted his way, and Izuku quickly turned his attention back to his bag, well aware that his face was burning bright red. They were both still brand new to the agency, and he was pretty sure it was a bad look, to be caught perving at another sidekick. Surely they couldn’t have noticed though, right? None of them had mind-reading quirks, at least that he was aware of, and who the hell was gonna see a guy stare for a second and immediately jump to ah, yes, staring at the nipple piercing and wondering whether it was his idea or his girlfriend’s.
Why was he so fixated on that thought? He’d never had any interest in their relationship before, aside from the vague thought of what did she see in him – well, other than being hot. Most pro-heroes were hot, so that wasn’t exactly an exceptional quality.
People were trickling out to the training field, so Izuku quickly finished zipping up his jumpsuit, hurrying after them. Bakugou’s costume was pretty skin tight, did that not irritate the piercing? It hadn’t looked particularly red or inflamed, so clearly he’d had it long enough for it to heal properly – which took, what? Weeks? Months? – but he was surprised the rub of that thick, tight costume material didn’t constantly irritate it.
“We’re gonna start off with some sparring, listen out for your partner,” All Might was saying, when Izuku hurried out to the training field. Izuku still felt so damn lucky that All Might had decided to reboot his old agency, to take in new recruits and help train them up for the job. “Todoroki and Yaoyorozu. Bakugou and Midoriya. Iida and Uraraka...”
Izuku turned his head, finding Bakugou already glaring his way. He didn’t dare to meet those fiery red eyes, didn’t want to give him any more reason to mop the floor with Izuku than he already had. Every time they’d sparred in the past, as rare as that was, Bakugou had beat him down like he was a child. Admittedly, it had taken Izuku a long time to get any kind of control over his quirk, while Bakugou apparently did it effortlessly, so it wasn’t surprising that Bakugou was so mad about having to work with him on their first day as pros.
Bakugou didn’t bother to say anything, just jerked his head for Izuku to follow, and Izuku scurried after him obediently, off to an empty space in a far corner. He’d left enough room to use his quirk without having to worry too much about the people around them, and Izuku swallowed hard, biting down on his lip to make sure it wouldn’t tremble. No matter how many classes and trainings they’d had, he still got nervous any time he had to spar with someone new – or, almost new.
All Might blew his whistle, and Bakugou wasted no time, a quick burst of explosion signalling his immediate attack. Izuku ducked to the left, raising both arms to protect his face from the punch that swung his way. It connected solidly, but the force was a lot less brutal with both arms to spread it over, and he took the opportunity to pivot on one foot, lifting a leg and using the momentum to swing it into Bakugou’s side. He grunted, two hot bursts of his quirk pushing Izuku away but not causing any real damage, so Izuku took the opportunity to finally power up his quirk – it still took him a second of concentration to get it there, and Bakugou had clearly not been willing to give him that moment he needed.
Bakugou’s arms flung out to the side, building up his next attack, and Izuku’s quirk wavered. The fabric pulled tight across Bakugou’s chest, highlighting the curves of his muscle, and suddenly there it was, a little raised edge along the middle of his pec.
“What the fuck?” Bakugou demanded, when Izuku’s quirk fizzled out again immediately. “You think all those fuckin’ training sessions with All Might made you better than me or something? Won’t even use your fuckin’ quirk against me?”
“W-What?”
Izuku blinked at him like an idiot, fumbling for words, but Bakugou didn’t give him any time to recover, already peppering him with tiny bullets of explosion that had him on the run before he could even think of retaliating.
“I don’t know what you’re talking about!” he yelled back, as he hit the ground to avoid a spray, taking the moment of breathing room it gave him to power up his quirk again. “You had just as many classes with him as I did!”
“You think I’m stupid?”
“No!”
So Bakugou had noticed, then. The one guy who wouldn’t hesitate to tell the whole world about the favouritism, who wouldn’t care if Izuku begged and pleaded him to keep his mouth shut. He was screwed. Completely, utterly, and helplessly screwed.
“You fuckin’ need it,” Bakugou scoffed, when Izuku managed to roll back to his feet, before Bakugou could blast him on the ground. “Clearly it’s not working.”
“I don’t know what—”
“Fucking save it!”
Izuku took a quick step back to avoid the swing, then leaned to the side to let Bakugou’s front kick pass him by. While Bakugou was off balance, he took another step, giving himself that moment of distance he needed once again, sending all of that crackling power that ran through his veins straight into his fist. He wound back, but Bakugou stepped in close – too close. Izuku couldn’t get a solid hit on him at that distance, and he knew it, but worse...
Izuku scrambled backwards and hit the ground, Bakugou immediately dropping to pin him there, his hands hot and sweaty where they gripped Izuku’s arms, slamming them into the ground above his head.
“Why the fuck are you so distracted?” Bakugou demanded. “You’ve had three years of hero training, and you’re suddenly acting like a damn rookie again? I thought you had improved.”
“You did?”
“Haah?”
“You thought I’d improved?” Izuku clarified, his face burning. “Thank you.”
“Not like you could get worse,” Bakugou huffed. “I don’t give a shit what you do in your free time, even if you are sneaking off with All Might to do it. Better not be some creepy shit.”
“What?! No! We’re just training! Like you said! But, uh—”
“Relax, nerd-ass, not like I’m gonna blab and shit,” Bakugou said with a scowl, his grip squeezing tighter on Izuku’s arms, though some of the heat had faded a little at least. “Like I said, you fucking need it.”
“I know,” Izuku admitted. “Um, thanks. Can we... Try again?”
“Not until you stop being so fucking distracted.”
Izuku’s eyes darted down, and Bakugou’s face changed immediately, his narrowed eyes shooting open a little wider, his scowl turning into something more surprised, and then slowly stretching into a smirk.
“Really?” he asked, sneering. “What, graduation was the cue for your stupid brain to wake up and realise I’m hot?”
Izuku whined, but Bakugou didn’t back off, and Izuku knew it was pointless to ask.
“What exactly do you plan to do if you meet a hot villain, huh? Let a fuckin’ city burn so you can perv at their ass?”
“What?! No!”
“Then get used to it, asshole. The fuck has gotten into you today?”
“How long have you had it pierced?”
He regretted the words immediately, his face so hot it could have rivalled Bakugou’s quirk. Why had he let that slip out?! He hadn’t even thought the words, they’d come out of his mouth before his brain had even caught up!
Bakugou’s eyes just widened again, though, and this time his grip loosened a little. If Izuku had tried really hard, and hadn’t been so mortified, he might have been able to break out of the grip, flip their positions with some help from his quirk, or at least knock Bakugou off balance again for a second to let him slip out and run away, never to be seen again.
Alas, Izuku was not in any kind of shape for that. Least of all with Bakugou’s knees pinning his legs in place, one of them painfully close to his crotch. If he wiggled just right – or just wrong, as it may have been – he was pretty sure that leg was going to cause him a lot of pain.
The whistle blew for them to change partners, and Bakugou thankfully climbed off him, though he didn’t deign to offer Izuku a hand up. He didn’t even have a scratch or a patch of dirt on him, still as impeccable and put together as they’d started out, and Izuku whined to himself quietly as he stayed in the grass, wishing it would just swallow him up, make him part of the earth.
“Everything okay, Deku-kun?”
He lifted his head slowly, finding a concerned Ochako leaning over him, offering him the hand that Bakugou had refused to extend. He accepted it gratefully, resigned to his fate of remaining human, and she glanced over at Bakugou’s retreating back as Izuku brushed off his costume.
“He’s a real jerk sometimes,” she said sympathetically. “Sorry you got stuck with him.”
“He’s really talented,” Izuku admitted, glancing after him too and hoping he wouldn’t look back and catch it. “I understand why he’d be annoyed to have to work with me again, it won’t teach him anything new.”
“Give it time!” Ochako insisted, slinging an arm around his waist and leading him back to the group. “You’ve mastered that power of yours, you’re just having an off day! Understandably! Soon enough you’ll be kicking even Bakugou’s butt out here!”
Izuku smiled faintly, returning her one-armed hug before they split again to find out their next partners. He didn’t believe the words, not in the slightest, but he appreciated that someone could still be optimistic about his chances.

Katsuki didn’t like to linger in changing rooms. They were smelly at the best of times, and outright disgusting at the worst; he’d hoped being in a professional agency, away from the hormones and poor hygiene habits of teenagers, that they’d be a little better, but apparently some things never changed. They were also full of sidekicks he didn’t want to talk to, half of whom he didn’t even know the names of, but who apparently, inexplicably, wanted to talk to him. Worst of all, half the time they devolved into stupid fights with wet towels or sweaty costumes, as they packed their belongings away for the night. They were supposed to have grown out of that shit by the time they became adults, but apparently some of them had missed the memo.
Usually, Katsuki just shoved his costume in a laundry bag, threw his clothes on haphazardly, and practically ran out the door to get back home. That day, though, he had... things to do. Half the sidekicks had already left, decided to shower in the privacy of their own apartments rather than the dank agency bathrooms, and Katsuki kind of envied that decision – he certainly would have done the same, any other day.
Instead, Katsuki took his time in the communal showers, washing his hair first, then running his wash cloth over every bit of his body, lathering them all up in his favourite body soap. He could feel the eyes burning into him as he worked, and if he occasionally bent over a little further or longer than usual, who could blame him? Everyone appreciated being admired, right? Especially when it was by that weirdo nerd who got on every last nerve Katsuki had, but was also kind of cute. He couldn’t say that about most sidekicks.
Well, weirdos and nerds and getting on his nerves, those he could say about most of them. But cute? No, that one was rarer.
But there he was, with those big green doe-eyes, and his stupid freckled cheeks, and that mop of hair that Katsuki didn’t think had seen a comb in his life. If he’d stopped wearing those dumb t-shirts and baggy pants, taken a little more care with himself, he could’ve been a hell of a looker, but instead he was just kind of... plain. At first glance, at least. Katsuki had seen him change, too – it wasn’t a one way street, as much as he was sure Midoriya assumed it. His arms were scarred from all the stupid shit he’d done in their time at U.A., but they were strong as hell, and with those thighs like fuckin’ tree trunks, Katsuki was pretty sure Midoriya could throw him around pretty damn easily, given half a chance. Katsuki still hadn’t gotten used to being around people who were just as strong as he was, let alone potentially stronger. Not that he’d ever say that out loud.
Midoriya shoved his head under the stream of water, clearly trying to drown out a bunch of stupid thoughts, and Katsuki smirked to himself. Only two more people to go, then Katsuki was home free.
“We’ll see you tomorrow, Midoriya,” Todoroki called.
“Unless you want us to wait?” Iida offered.
Katsuki could see it in his eyes, the temptation to say yes, please, wait for me, but he was nothing if he wasn’t selfless – another trait Katsuki hated about him, always giving up his own well-being for someone else’s. Gross.
“I’m okay, I’ll head home soon!” Midoriya promised, with a fake brightness in his tone.
Good.
Katsuki slid over to stand next to him, and Midoriya nearly jumped out his skin when he saw – good, Katsuki was still doing okay in the stealth department, then.
“Been eyeing me up again, nerd?” Katsuki teased. “I could practically hear your damn boner.”
“I was not— I didn’t have— Shut up!”
“So eloquent,” Katsuki said with a snort. “Don’t try to bullshit me, like I couldn’t feel you staring at me.”
“Sorry,” Midoriya whispered, catching Katsuki off guard.
He pulled away a little, putting space between them, but Katsuki followed him step for step, and then one more for good measure.
“You want to touch it?”
Midoriya blinked at him, with those stupid shiny eyes of his, and Katsuki just raised an eyebrow.
“Well?”
“C-Can I?”
“As long as you haven’t had your hands on your damn cock while you stared.”
“What?! No!”
Katsuki handed him a bar of soap all the same, watching his face turn bright red as he cleaned them off obediently.
“You asked how long I’ve had it,” Katsuki said, not meeting Midoriya’s eyes when they rose. “I got it right after we graduated.”
“Oh.”
He could practically see the gears whirring in Midoriya’s brain, but he decided to take pity, for once – he had a motive here, after all.
“My parents were always shitty about following uniform rules, they gave me enough of a hard time for not wearing a tie,” he clarified. “So the moment we finished, I told my parents I wanted an earring. Old hag was pissed off, but the old man said a bunch of shit about self-expression, so they caved.”
“And you changed your mind?”
“Nah, I never actually wanted the ear.”
“Oh. I uh, I thought you hated lying.”
“I do,” Katsuki said, raising an eyebrow – how did Midoriya know that? “Old folks don’t count.”
Midoriya cracked a smile, and Katsuki reached out, gripping his wrist and lifting it to line up with his chest.
“Doesn’t hurt,” he clarified, releasing the hand and letting it just hover there awkwardly. “Feels... good.”
That seemed to be all the reassurance Midoriya needed, because his hand came to rest lightly against the metal, feeling the smooth titanium under his callused fingertips. When Katsuki didn’t respond, didn’t shove him away or laugh at him – honestly, it was kind of tempting – he grew a little bolder, his thumb flicking across Katsuki’s nipple and making him stand up a little straighter at the sensation.
“What does it feel like?”
“Told you,” Katsuki said, shrugging. “Good.”
“Yeah?”
“Yeah. Why, you wanna lick it or something?”
Midoriya stared at him, and Katsuki smirked. Clearly the nerd hadn’t thought of that, but judging by the way his cock twitched, he clearly wasn’t opposed.
Midoriya leaned in, his tongue darting out to run across the metal, and Katsuki’s breath hitched. He’d just wanted the thing for the aesthetics, because of that one guitarist he liked, he hadn’t even considered how fucking hot it would feel to have someone lick it. Because honestly? Gross. And yet it felt really damn good.
Lips wrapped around his nipple, sucking gently, and Katsuki let out a gasp, head falling back and letting water stream down his face. He probably should have picked a better spot for it, somewhere he could at least sit down, but the opportunity had been too good to pass up.
Big, rough hands landed on Katsuki’s bare waist, guiding him, and cold tiles at his back made it clear that Midoriya had seen his knees tremble. He pressed Katsuki into the wall, giving him some much needed stability, but his lips and tongue never left Katsuki’s nipple.
“Fuck,” he hissed, when Midoriya’s hand roamed again, gently landing on his thigh. “Do it.”
The hand drifted closer, giving Katsuki ample time to stop him, but Katsuki just wanted to slap him for it, to tell him to get the fuck on with it.
The long fingers finally closed around Katsuki’s dick, and he groaned, throwing his head back again and this time finding the wall to rest it against, no stupid shower head spraying him right in the face. As much as he wanted to deny it, he knew it was going to be over quickly as hell, and he just had to hope Midoriya didn’t have enough – or, any – experience to know the difference.
“It’s okay, Bakugou,” Midoriya whispered, hesitating for a second. “Katsuki. Let it out.”
Katsuki’s lips parted, a moan breaking out of him, and Midoriya’s – Izuku’s – hand began to move a little quicker. It was way too dry, considering they were drenched with water, and Izuku’s hand was clumsy, but still he worked valiantly, and it wasn’t like Katsuki had had better. His own stupid, sweaty hand was all the experience he had, so just having someone else do it was enough, really.
With a last pathetic gasp, Katsuki came, and Izuku’s sticky hand gave him one last stroke before he let go, stepping away to wash it off. Katsuki cracked his eyes open to look, his smirk coming back quickly when he found Izuku bright red in the face, his own dick hanging limp between his legs – clearly both hands had been busy, the damn pervert.
“Sorry,” Izuku mumbled, as he grabbed the bar of soap again and scrubbed his hands and thighs clean. “I probably shouldn’t have done that, especially—I mean, what’s Ashido gonna think?”
“Raccoon Face?” Katsuki asked, raising an eyebrow despite his veritable exhaustion. “Why would she care? She's been telling me for years to find some cute dude to fuck.”
“W-What? Why would she want that?”
“I dunno, girls are weird. Double dates with her and Kirishima and all that lame shit, probably. She'd prefer a girl to hang out with, considering all her friends are dudes already, but that ain't gonna happen with my gay ass.”
“Your what?”
“You think straight dudes let other dudes jerk them off in the showers?” Katsuki asked pointedly. “What, you think you’re straight or something?”
“God no,” Izuku answered immediately, scoffing and making Katsuki’s smirk twitch a little wider. “I just thought...”
He trailed off, and it took Katsuki a moment to catch on.
“Me and Pinky?” he asked, the disbelief obvious in his tone, even to himself. “Fuck no.”
“W-Well, you’re always hanging out, so...”
“You never had a friend before?”
“Shut up!” Izuku answered defensively, huffing. “It’s different!”
“Sure, nerd.” Katsuki stood up, grimacing when he saw the cum sticking to his legs and feet. “Damn it, gonna have to shower again because of you.”
“Yeah, because of me,” Izuku scoffed, clearly regretting the tone immediately from the way his eyes widened. “I mean—”
“You mean what you said,” Katsuki chuckled, snatching his soap from Izuku’s hands before he could drop it in his distracted state. “Next time you’ll have to swallow, save some of the mess.”
He’d just been joking, obviously, but the way Izuku’s head whipped around, the way his eyes widened and his entire upper body blushed, told Katsuki maybe it wasn’t so far-fetched after all.
“Pervert,” Katsuki snorted, cleaning himself off and shutting off the water. “Better give me a good match, next time. No stupid distractions anymore.”
“Your entire existence is a distraction.”
Katsuki grinned, looking back over his shoulder to see the exhaustion in Izuku’s expression, the embarrassment that still seemed to run through his very veins.
“Damn right it is,” he said, watching a tiny smile sneak onto Izuku’s face. “But next time, just come to my place, instead of showing off your perversions to the entire world.”
Izuku squared his shoulders like he might argue, for a second, then immediately slumped again, too tired to have any fight left in him.
A pity, really. Katsuki liked it when the nerd got fired up.
“Maybe you should come to mine,” Izuku suggested quietly. “Instead of googling how to show off in the shower.”
Katsuki barked out a laugh, so much more genuine than he thought he’d laughed in... years.
“Be careful what you wish for,” he said, watching Izuku’s smiled stretch a little wider. “You think I won’t?”
“I’ll believe it when I see it.”
Katsuki snorted.
“Challenge accepted,” he said with a smirk, watching Izuku immediately fill with nerves – clearly he hadn’t expected that. “Seven o’clock, be there”
“Seven-thirty?” Izuku suggested. “I normally have dinner at seven.”
“Ugh. I hate you night owls. Fine, whatever. Seven-thirty, but you have to supply the lube.”
“Lube?”
Katsuki raised an eyebrow, and Izuku’s confident demeanour disappeared in an instant, blushing again instead.
“I know what lube is,” he clarified, before Katsuki could laugh at him. “But why do we...? Forget it, I have lube, it’s fine.”
“Damn right,” Katsuki said, grabbing his towel and heading for his bag to get dressed. “See you at seven-thirty sharp, no extras allowed, and no fuckin’ foreplay.”
“Deal on the time and the friends,” Izuku assured him. “But there’s gonna be a lot of foreplay, just you try to stop me.”
Katsuki laughed again, and Izuku’s face softened, from his careful confidence into something more... fond.
“We’ll see about that, Deku,” Katsuki sneered.
He knew all the stupid shit that had come with his choice of hero name, but he couldn’t help but push that button, just a little. It seemed to have the opposite effect of what he’d intended, though, since Izuku stood up straighter, a look of determination crossing his face like nothing Katsuki had ever seen before – even in battle, when he was saving civilians and shit. That was a concerning thought.
“Yeah, we will,” Izuku said firmly, his tone making Katsuki’s stomach swirl. “See you then, Kacchan.”
Katsuki hurried out the door with his pants half-zipped, to keep Izuku from seeing the flush that came over him, spreading from his cheeks right down to his nipples, to the stupid piercing he’d gotten on a whim that had started the whole thing in the first place.
Suddenly, he was glad he’d accepted All Might’s offer.
