Chapter Text
Katsuki Bakugou had a secret.
Well, not really. He didn't consider it as such and didn't even think about it for more than a few times a month, maybe a few times a year.
It was something that ran in his family, like a residual quirk manifestation - sort of like Mina's horns. His dad said he had it - it wasn't something he was going to check - and his grandfather, and great-grandpa.
You couldn't even see it unless you were looking for it. I mean, his doctors knew, the old lady knew, but even she didn't bring it up because in all honesty, it had very little relevance in his life.
That was until now.
He wasn't sure what got them in this position. They were in a bathroom stall, Katsuki's back slamming against the door, rattling the metal lock. The beat from outside pulsed dully, the music just an indistinguishable muffle.
Katsuki had always been law abiding to a fault- I mean, you didn't get on the hero track by being a delinquent. It was therefore one of the first times he had touched alcohol today, on Eijirou's 20th birthday. He wouldn't have chosen a club and certainly not with an open bar, but he and Deku had been on a mission till yesterday, and all the others had jobs more far afield. Of all people, the organisation of the party had been left to Mina, Denki and Shouto.
All told, the party team therefore had a single brain cell that fizzed most days and deep pockets with an indulgent attitude. Turned out it was the worst combination ever; for taste and class, that is. They'd booked out the small club that usually had a live band, decorated with balloon arches, animal print and bedazzled in all sorts of glittery decoration.
Eijirou and Katsuki had been on patrol; Katsuki had moved to Kyoto after they graduated, refusing to work with Endeavour when Miruko offered to take him up. Her nomadic style soothed him because he became a household name in several cities, and while they'd stuck to Kanto for a while, she had struck gold in Kyoto one day when the severe downturn of hero number still plaguing the country ended up with her landing a major position on the majoral board for the old capital.
So off they went to Kyoto. Eijirou still worked with Fatgum's out of Osaka, so with it being only an hour away by train, Katsuki was more than a little relieved to be able to see his favourite man more often than the first few months after graduation had afforded. The agencies, being close, perennially short of staff and friendly with one another - as friendly as Bakugou and Miruko could get - worked together often. Today had been one of those days, a shared mission to patrol a particular area and aid the police to round up some drug dealers.
They were dirty, and hungry, and wet from the mid-October rain. It's a thin mist of water, but just enough to get you wet and freezing. If you're not Kirishima 'take-your-shirt-off-in-the-snow' Eijirou, that is. He was still shirtless, had yet to add the sleeves to his costume because it's not winter yet, Katsuki! It's barely autumn!
So when they joined the others at the bar, their hair was floppy from waterlog, their everything was cold, and some sake sounded like a good bloody idea to warm up.
Only, Katsuki didn't drink, and he hadn't eaten in almost ten hours, and who the FUCK knew sake hit like this?
They'd come into the bathroom to change. Fucking half-and-half and Mina had gotten them outfits to get out of their uniforms and into the 'party vibe'. They'd started just playfully pushing at each other, then pulling wet clothes off. One second, Katsuki was smirking at him about floppy hair and asking if it was the only thing floppy.
Then the sake hit. Or, well… he was blaming the sake.
And the next minute their hands were all over each other, his nether regions hot like he'd never felt them before. Kirishima could have stolen his quirk for all he knew because his hands were scalding on his skin. Clothes were flying everywhere, and Katsuki just pushed Eijirou into an open stall and locked it behind him, sitting himself onto Kirishima's lap. They were kissing like drowning men, and considering that Katsuki had never fucking kissed anyone before, this was a fucking revelation. He tilted his head when Kirishima did, let him hold his head; bend his neck; press him to the redhead by the waist. Hot palms splayed on his lower back and finger curling into his undercut. Katsuki kept his own hands balled, sparks going off, wrists pressing into Kirishima instead.
The redhead was strong. Katsuki knew it better than ever in the next moment when he lifted the blond up with one arm, slammed him against the stall door. His trousers had already been off, but Kirishima just grabbed his underwear and tore. It shouldn't have been as hot as it was, but the second Kirishima wrapped his lips around his teeth and dove into his painfully erect cock, Katsuki lost his mind. The back of his head slammed against the door, his back tried to curve but Kirishima held him in place. Pleasure exploded up his body from his centre, Kirishima's mouth wet and hot in all the perfect ways. Kirishima's name came out in broken syllables, and Katsuki couldn't stop it if he tried.
He came messily, elbows hooked onto the two coat hooks on either side of the door, voice hoarse, praise falling from him like rain.
Eijirou got off him and began kissing his stomach, his chest, his neck as he was lowered down. Kirishima fought with his belt, and then it was off and his trousers were around his ankles. Katsuki's mouth went drier than dry when he saw that Eijirou didn't have underwear on. And his dick was fucking perfect - long, wide just enough, elegantly curved. Katsuki may have whimpered, but he had no idea what he was doing at this point anyway.
Eijirou pressed his dick in the cleft of Katsuki's cheeks, gently undulating up and down, massaging Katsuki's cheeks to rub against him. Katsuki was going mad.
"Higher," he said, trying to swallow but finding no moisture.
"Wha-?" Eijirou asked breathlessly.
"Higher," Katsuki croaked, unhooking one elbow to paw at the redhead's dick and angle it upwards. Eijirou's pupils dilated visibly even in the low light of the bathroom. He whined in a way that went right down Katsuki's spine, his dick trying valiantly to rise again.
"I, I have to prep you, and we have no lube," Eijirou said in a voice at least two octaves below his normal register. Katsuki's dick twitched.
"No need," Katsuki growled back. Fumbling, trying to keep his balance, Katsuki managed to take Eijirou's dick in his hand again, sweaty as they were, and placed the tip where he wanted it.
Eijirou's hips stuttered up instinctively, and his jaw fell loose, eyes rolling back as the tip went in. He groaned, fell against Katsuki's chest, and then started pushing in.
There was burn, at first; sort of like a carpet rubbing you wrong. But within seconds it felt so fucking good Katsuki was as lost as Eijirou, who started babbling nonsense. Beautiful, love, darling; all manner of sweet shit slurred with lips smeared against his pectorals. Katsuki had never known himself to feel so hot, so cold, so electrified and yet helpless. His limbs felt like rubber, and then stronger than they had ever been. His legs locked around Eijirou's hips, his ankles linking in place like an anchor coil.
Everything was rising higher and higher and fucking higher, until-
Eijirou came with an obscene moan. Katsuki had barely noticed he was hard again, but disappointment washed over him as Eijirou stuttered and then slumped, before it morphed into something warm and proud.
He'd made Eijirou come.
"Wha, whadda," the redhead slurred. His come was leaking out around his softening member.
"Doesn't have anywhere to go," Katsuki replied, relaxed more than he'd ever been in his life. Sure, he was slightly frustrated, but he'd already had one mind-blowing orgasm. May as well let the birthday boy enjoy himself.
"Whaddja mean?" Eijirou said, clearly still out of it.
"Secondary quirk thing, I'll explain later," he replied, rubbing Eijirou's hair between his fingers. Ah, gods, he wished they could escape somewhere, be just the two of them. Just as Eijirou let him down, Katsuki barely avoiding getting his elbow caught in the hook awkwardly, they almost slipped in it, and both of them snorted and chuckled, and then started giggling like bloody idiots. Katsuki was nude from the waist down, and swore colourfully when he gingerly fingered his limp underwear. Eijirou apologised in horror, but Katsuki was too elated, his spirits too high. He got it now, why people actually went after and risked so much for a lay. Just being able to sleep a little more relaxed had never seemed worth the mess and effort to him before.
But with Eijirou it was different. With Eijirou, everything was different.
They got dressed, and at least Katsuki was relieved that the trousers half-and-half got him were the baggy sort that wouldn't chafe his naked ass. He helped Eijirou pull up his hair into a messy ponytail, and Eijirou very much couldn't seem to keep his hands away from Katsuki either.
That was until Denki practically fell into the bathroom, already plastered, and dragged Eijirou away. That was almost the last Katsuki saw of him all night, with him being passed around like a party favour, everyone pouring him a drink (and everyone teasing Shoiji and all the others who hadn't hit majority yet and had to take non-alcoholic drinks).
By the end of the party, Kirishima was a complete disaster. Hair everywhere, cheeks so pink they glowed, eyes shining but very clearly vacant. He tumbled into Katsuki's chest, laughing brightly, rubbing his cheek against his pectoral.
"Kass'ki!" He slurred. Katsuki couldn't help the snicker that escaped him. "Ya titsh a'so pretty"
"Yeah, yeah, ya drunk," he snorted, holding the redhead up. "I'll take him home."
"Oh thank heavens, Blasty!" Mina moaned. "I think I drank enough to skip the hurling and go straight into hangover, ung. You work tomorrow?"
"Serves you right," Katsuki rebutted, standing off the barstool and hefting Kirishima up under one armpit, around his back and palming the other. Fucker was heavy. "We're off duty. I cleared my tab an hour ago, go clear yours. Half-and-half!"
Shouto looked over from where he was ensconced… with Sero. Huh, he had to keep an eye on that for both their sakes.
"Yes?" came the reply that tried very hard to sound as bland as usual. Hum.
"Take care of them for me," he replied. Deku wasn't here anymore, so half-and-half would have to do. He'd speak to Sero some time this week, too.
At Shouto's nod, he heaved Kirishima up again, hitched him against his side as much as possible, and hobbled out, booking a cab on his phone as he went.
That was how it began; but that was certainly not how it ended.
°°°°°°°°°°°°
"Your first time?! That can't have been your first time! Dude; tell me you're joking, please!" Kirishima wailed, hiding his face in his hands and groaning. Katsuki looked at him, nonplussed.
They were at a café a week later, a comfortable little place near Hirakata park, half way for both of them on the Shinkansen. They had agreed to meet, since Katsuki had spent the morning after taking care of a very ill Kirishima, before having to return home in order to prepare for the night shift he'd start at 10pm. There was precious little they had managed to speak of, and a lot they needed to clear up.
So here they were, in a small café, window seat in view of the park wheel on a cloudy Tuesday afternoon.
"What's the big deal?" Katsuki replied, understanding on some level, but also not really. "It was good."
Kirishima didn't raise his face from his hands, but his ears went red. He mumbled something.
"What?"
"I said," Kirishima repeated, taking his hands away, "that it was in a toilet stall! It was supposed to be special!"
Katsuki felt oddly flattered, but Kirishima was just being a soft idiot as usual.
"You're not listening. It was good." Kirishima's colour deepened and this time Katsuki had the pleasure of watching it overtake his face. "And it was with you, so it was better."
"Still," the redhead said, eyes darting to his face with some more confidence than before. "It shouldn't have been like that..I didn't even ask, hell's goons."
"I said yes all the way," Katsuki reassured. He would normally be losing patience at this point, but Kirishima wasn't being obtuse: he genuinely felt this much, and Katsuki had learned to appreciate that. "Fuck, I put you inside."
Kirishima honest to Amaterasu squeaked. He had to stop himself from snorting.
"A-about that," he said in a small voice. Katsuki braced himself, knowing the question was coming. "What if, I mean, is there a chance you're, um, pregnant?"
Good thing he hadn't been drinking.
"No; s'just a pipe," Katsuki said. "Leads to nowhere. You know how Mina's horns are just there and don't do anything? Or Tokoyami's head is just…. Pointless bird? Their quirks have nothing to do with it, but some great great great grandfather had horns they used, and they stuck around."
"And you have a, um …" Kirishima floundered. He was fucking adorable.
"Sort of cunt, yeah," Katsuki replied casually, more to see him squirm than anything. "Pa's got one too. Grandpa thrice removed had a quirk where he could blow this bouncy ball out that hole that was super resistant and could only break when he popped it with fluid from his hand. Hand sweat quirk stuck around, but the bubble-ass shit didn't. Thank heaven," he added, and Kirishima snorted.
"I can't… imagine…" Kirishima was a mess of choked laughter for the next five minutes.
"Apparently could bounce him around on his seat real high and shit," Katsuki went on, thoroughly enjoying the show of Kirishima losing his mind with laughter. "He went around with these pants with two buttons and a flap and when someone pissed him off he just- mooned them, blew an ass bubble and bounced off."
"St-o-o-o-p please!" Kirishima begged, holding his belly which was obviously cramping with laughter.
"But yeah, no need to worry about making babies," Katsuki concluded as Kirishima gasped and wiped his eyes. Katsuki smiled at him, sipping his coffee and watching him regain control over the cup rim.
"You're not shitting me with this?" he finally asked.
"No. It's got its uses, but making babies isn't one of them. Well, sort of; the process is the same," Katsuki said. Eijirou went quiet, his pupils dilating again as his eyes fell to a point on the table that, if he could see through the wood, landed straight on the blond's crotch. "Gets wet when I'm having fun too; convenient."
"So, you …"
"It was good, Eijirou. It was great." He sighed but didn't relent, because he knew the redhead was a fucking idiot about some things. "You made it good, ok?"
Eijirou looked up at him from under his lashes, and Katsuki just smiled, before holding his hand, palm up, on the table. Kirishima blushed hard again, but scrambled to cover Katsuki's hand with his own. It was awkward and uncomfortable, but they smiled at one another.
They were silent for a few moments, simply holding each others' hands as the café bustled around them and their coffees got cold.
"So, um," Eijirou began again.
"Was it yours?" Katsuki interrupted, trying for nonchalance, but failing spectacularly. Still, it was out now.
"What?"
"First time," he insisted.
"Oh. Um. Sort of." Kirishima scratched his head with his free hand. "I fooled around with a dude in a club once. Same thing, in a toilet stall… it felt awful after, you know. So I didn't want you to feel the same."
It stung a little, that he wasn't Kirishima's first everything. But also…
"I told you, idiot, it was great because it was you. And it was your first time inside, right?" Katsuki could admit he felt fucking smug about it, and Eijirou just kept blushing and nodded. "That's what counts," he decided, even if it wasn't necessarily true. "Anyway, what were you going to ask?"
"Huh? Oh...just, just if, you know. If you liked it because it was me, I was wondering if you wanted, maybe…"
"You wanna do it again, you perv?" Katsuki teased.
"No! I mean, what, I am- yes but also no, I mean," Kirishima floundered. "I just want to date you! But also you're too hot and my brain stops working, so stop teasing!"
There was the absolutely gobsmacking feeling of pure flattery again.
"Shit yeah, I'd date the fuck outta you," Katsuki replied with a smirk. Kirishima's elated expression as he looked up brought the sun back into the cloudy day. Katsuki was rapidly becoming addicted to putting that expression there. "We can start now."
"Huh?" Kirishima said, and Katsuki also liked him looking like a confused puppy, head tilted and slightly muddled. He nodded at the waitress, who came quickly and then rushed off to get their bill.
"Let's go to the park; it's 10:30 AM, it's open. Let's make this a date," Katsuki said. Kirishima stared at him for long enough that he started feeling antsy. The waitress came with the bill, which Katsuki promptly covered, and that seemed to break Kirishima out of his reverie.
"Hey …"
"You can buy us tickets, if you want," he said, and waited. He'd learned a thing or two, and patience always came easier with Kirishima anyway.
"Oh heck yeah, you mean it!" The redhead was looking at him the way he looked at his vintage, signed Crimson Riot poster. Katsuki decided to take the win.
"Let's go," he smirked, standing up and throwing his jacket on. Kirishima, always in nothing more than a hoodie, stood awkwardly beside him until he was done, and then shyly offered his hand. Katsuki took it, making it a point to entwine their fingers.
By the end of the day, as afternoon passed into evening, they'd been on all the rides, stopped at a photo booth, eaten junk food from the Pansy takeout truck and then bought ice cream to take up with them on the Ferris wheel. Katsuki stole a kiss when they reached the top, and by the time they got out, they were freezing but happy, throwing the cones away and huddling together to share Katsuki's scarf.
