Work Text:
Bakugou downed his beer in one go, the dark circles under his eyes a true testament to how little he’d slept that week.
To say it’d been rough would be an understatement. What with a new stupid case and Deku always trailing after him and their whole agency undergoing renovations on account of one of his outbursts that ended with half of the building in shambles.
No, rough was too nice of a word to describe Katsuki’s week.
“Hey, Kacchan, are you okay? Maybe we should just call it a night, what do you say?” Deku’s voice took him away from his thoughts.
Typical Deku, annoying, and inconvenient. Well, except for when he brought him his pint, that had actually been kind of useful.
His sidekick just looked at him, a worried expression on his freckled face.
From where Katsuki was sitting (in a booth, right in front of Deku), his sidekick seemed to be almost looming over him. Logically, he knew he wasn’t but goddammit, why was he taller than him?
“Shut up, stupid beta,” Katsuki said, nonetheless pushing his empty glass away from him. He did feel a bit sick.
Deku smiled minutely and started to rub his back in what he (wrongly) assumed to be soothing movements.
“There’s nothing wrong with being a light-weight, Kacchan,” he said, and though his voice seemed to be very sympathetic given his drunken state, a look at the mischief behind green eyes told Katsuki everything he needed to know.
That fucker, he thought, he's trying to one-up me.
“Fuck you,” he whispered, feeling the slightest bit flustered, the point of his ears feeling warmer than usual.
“No,” Deku said, a weird edge to his voice, “fuck you, boss.”
--
Katsuki’s night had ended with him puking the beer he’d had right into his toilet bowl, then dragging his tired body toward his bed.
When he woke up the next day, his head pounding and ears ringing and feeling like the textbook version of your typical hangover, he remembered how Deku, a mere beta had helped him out of their usual booth at their usual bar and inside his car.
Deku had driven his drunk ass home. Great.
Deku was incredibly strong for a beta and his quirk wasn’t half bad. He could admit to that, well, inside his head anyway.
But none of that mattered anyhow.
All heroes had to be alphas.
Betas could aspire to be sidekicks at best and omegas… well, the only omega hero he knew was Recovery Girl, and even then it had been quite a struggle, the Pro Hero Association only letting her work due to healing quirks being in high demand.
Such was the world that they lived in.
Alphas were meant to protect, Betas were there to serve the alphas and omegas were meant to mate alphas and have healthy pups that would grow up into functional members of society.
Alphas were strong, omegas were soft. Together they were the perfect balance, the yin to the yang and all that bullshit.
Then why, pray tell, was Katsuki so averse to the idea of mating one?
Katsuki groaned when he finally accepted his fate and got out of bed, the whole world around him shifting momentarily. It wasn’t even six in the morning and the whole fucking day was ruined already.
He checked his phone and found a lot of messages, half of them were photos of shitty hair with that dunce face and that kid with the tape quirk hanging out in the background.
One message from the old hag reminding him of the old man's birthday coming up next month and to "buy something nice or else".
There was also a message from the PR team about a press conference to be held the following day regarding the agency’s renovation. Fun.
And then there was a message from Deku.
It read: “I hope you made it home safe.”
Which was absolutely ridiculous. For one, because Deku had literally driven him home and then again, even if he hadn’t...
Katsuki was an alpha, a motherfucking hero, and a great one at that. He'd been awarded a mention as the most promising newcomer. (Well, resident pretty boy Todoroki Shouto had also been mentioned as the most promising newcomer hero, but who cares about that, right?)
He’d made more arrests and closed more cases that year than seasoned heroes the likes of Endeavor and Miruko.
He was the definition of safe.
Before changing into his uniform, Katsuki deleted nearly all of his messages, without even opening them.
Well, all of them except for Deku’s.
The mere notion of him needing that green menace to protect him was ludicrous and that message was clearly meant to mock him.
Obviously.
--
The villain had a quirk that allowed him to shapeshift. He called himself “Purple Chameleon” or something like that. To be honest, Katsuki hadn’t been paying too much attention.
Deku had been there beside him when they’d been handled the details concerning the villain after the dumbass had attempted to rob an art museum. After a kid had spotted him trying to camouflage himself and failing (because this B lister was also stupid as all fuck) the villain had escaped.
“Then why the fuck do we have to go after him?” he’d asked detective Tsukauchi. The man sighed and turned to Deku, who was by his side, much to Bakugou’s chagrin.
“We suspect he’s collaborating with a group of villains that have stolen around a thousand works of art from museums all over the world. We have reason to believe they have more competent villains in their ranks.”
Deku nodded, taking a step towards Tsukauchi’s desk to examine the pictures of the villain in question and in doing so, brushing Katsuki’s right shoulder.
“I understand, we’ll take care of it.”
Katsuki harrumphed, face dark red.
“You mean I will take care of it, stupid Deku, you’re just there to assist.”
Both Deku and Tsukauchi rolled their eyes.
--
Presently, the stupid Chameleon villain was a few feet away from him, Bakugou on hot pursuit, a big grin on his face.
The week had been absurdly busy and stressful and this one easy arrest could turn everything around for him. He just needed to reach that sucker so he could tell him where his villain friends were hiding.
Easy.
“Hah! Gotcha!” he screamed, fingertips almost reaching the villain’s ankle when he realized… it wasn’t the villain at all.
Turns out this fucker could camouflage more than his own dumb self. Once he touched what he believed to be the villain’s ankle, it promptly changed into an airplane toy.
It had been a trapt and worst of all, Katsuki had activated his quirk the second he’d gotten close to the villain and he was next to a construction site.
Of course, he thought while listening to Deku’s frantic screaming coming from his receiver, it had to happen to him.
--
When he came to, he was being carried by strong arms, was any other hero near his location when he’d try to make the arrest?
“Do you have him?”
Katsuki’s eyes couldn’t focus but he was almost sure that voice belonged to Deku.
“Yeah,” Uraraka said. Huh, so floaty bitch had made the arrest. Well good for her.
“Did you have to beat him so much? He looks terrible!”
Deku made a noise that sounded suspiciously like a roar. It sounded so stupid coming from a beta.
Stupid and calming, Katsuki thought, rubbing his face against the hero that was still holding him. Boy, was he strong. I mean, he was holding Bakugou after all, and he was almost pure muscle, right? So this dude had to be …
“Well,” he heard Deku say, “he’d tried to hurt Kacchan… I mean Ground Zero!”
Floaty bitch giggled.
“Oh, Deku, you have it bad.”
Wait…. why would she giggle?
Katsuki’s eyes started to feel heavy again. The mysterious hero did not seem to have realized he had momentarily regained consciousness.
Well, time to nap again then.
--
The first thing Bakugou saw once he woke up in a hospital bed, in a white sterile-looking room that should smell like nothing at all was…
“Fucking Deku,” he said, noticing how his voice was now rougher than usual, “you reek.”
Deku, who was sitting on a chair, impossibly close to his bed, rubbed his eyes, and once he realized he'd woken up, he hugged him tightly.
“Kacchan!” he screamed, eyes welling up with tears (of joy? Katsuki couldn’t tell).
“Ugh! Of course I’d wake up and find you of all people next to my bed, you leech,” Bakugou said, trying to shake Deku off of him.
Deku went back to sitting next to him.
“Sorry, Kacchan, I was happy to see you awake!”
Bakugou rubbed his eyes, careful not to accidentally pull out his IV line. That would be a pain in the ass.
“What happened?”
Deku blinked, a soft blush coloring his cheeks.
“You mean the arrest?”
Bakugou sighed and closed his eyes. God, did he wish he could fucking strangle Deku to death sometimes. Opening his eyes, being greeted by Deku’s confused frown he sighed again.
“No dumbass, I wanna know what happened with you and round face out there,” Katsuki made a pause to clear his throat. Fuck, he was hurting all over.
“You were awake?” Deku said, his blush intensifying tenfold.
Somehow, that didn’t sit well with Bakugou. Why would Deku blush? Was it because of …. Uraraka? Were they together?
“No,” Deku answered.
Fuck, he must have said that out loud.
Deku looked a lot more serious all of a sudden, "I'm not seeing anyone right now."
Katsuki rested his head back against the pillow.
“But you want to.”
Deku visibly gulped, then nodded.
Bakugou felt like he had stones in his stomach. Somehow he doubted it had anything to do with any physical ailment whatsoever.
“There’s… an alpha,” Deku said slowly, dragging his words out, “but he probably just wants a cute omega and not a…” he gestured towards himself as if that made any sense whatsoever.
Bakugou rolled his eyes, hard. Well, that was just rich. It was just like Deku to catch feelings for some unworthy alpha with a huge ego.
“Shut up, Deku.”
Deku stopped gesticulating and panicking once he realized Katsuki was talking to him.
“Not every alpha wants an omega.”
He felt again how the tip of his ears started to get warm for the umpteenth time that month. It only happened when he was near Deku, for some reason. Probably a coincidence.
--
The bar Kaminari had chosen for the three of them to hang out was, unsurprisingly, a really popular hip bar modeled after the NY subway, which was ridiculous. Who wants to relax and have a drink at a place that looked like a dirty subway station?
Kaminari and Kirishima, apparently.
Since it was popular, the bar was also packed. It was also a terrible excuse for Kaminari to hover over him and put his arm around his shoulder like the needy bitch he’d always been. Fuck, why were his friends so lame?
“So, get this,” Kaminari said, already on his third cocktail, “this dude totally thought that hot girl was the villain and then…”
Bakugou rolled his eyes.
“Can you fucking shut up for a second?”
Kirishima sighed, probably experiencing second-hand embarrassment once Kaminari started swaying while exaggerating his work-related anecdotes.
“You know, dude, maybe you’d had a little bit too much to drink and…”
Kirishima tried to prevent Kaminari from finishing his drink and once it, inevitably, dropped (staining Bakugou’s white hoodie, because of course it would) there was an eerie silence at their table.
Bakugou kept very still.
“Er… I’ll… I think I can see Jirou over there!” Kaminari said, standing up and making his way toward the bar in wobbly legs.
“Sorry bro, hey! I’ll get you a new one,” Kirishima, always the good sport, apologized in Kaminari’s stead.
Bakugou groaned but decided to let it go. Those dumbasses would be the end of him.
“You better, shitty hair, dunce face is as good as toast if he ever…”
Kirishima patted him on the back.
“Dude! Chill! He’s just being… well, himself,” he finished awkwardly. He smiled and somehow Bakugou was reminded of Deku and his big dumb smile. He was sort of useful in rescue missions. If Bakugou ever tried to smile reassuringly to any civilian they’d probably get scared shitless.
Kirishima waved his hand at him, and fine, maybe he’d had a bit much to drink as well. Maybe that’s why he was spacing out.
“You okay?” shitty hair said before a grin appeared on his face. Bakugou did not like that grin, not one bit.
“So…” he started, his grin becoming wider and wider, “Are you dating anyone? Any cute omega I should know about? Huh?”
This time it was Bakugou who dropped his drink, which again landed on his now completely ruined hoodie.
“The fuck do you mean, shitty hair?”
Kirishima shrugged, having the gall to keep on looking amused.
“Is it a beta?”
Bakugou was about to punch him when he was assaulted again with images of Deku smiling. Deku in his hero… sidekick suit, kicking ass. Deku’s muscles when they worked out together. Deku towering over him and ….
“Dude, you’re spacing out again.”
“Shut up!” he screamed. Great, he was probably blushing now. Fuck everything.
Kirishima whistled playfully.
“They must be quite a catch if you’re getting this flustered … hey! No punches inside the bar, ok?”
Bakugou lowered his fist.
“Doesn’t fucking matter, he likes someone else and I…”
“And you?” insisted Kirishima, now looking genuinely concerned.
Okay, so maybe he had overestimated his alcohol tolerance and should maybe shut up before spilling too much information but… this was Kirishima he was talking to. His quote-unquote best friend.
“I am a shitty alpha,” he finally said, “I fucking can’t have sex… not like… that.”
He didn’t want to say it.
Yes, he had dildos and lube he’d purchased online inside his bedside drawer but no one needed to know about those. Except that if he ever got with someone (anyone) that information would have to be shared and what kind of alpha likes getting it up the ass?
Kirishima didn’t ask him further questions. He could always tell what was on his mind.
“If you like him,” he started, his tone somewhere between serious and earnest, “and he likes you back, then I don’t think it will matter.”
--
Their shift was finally over and Bakugou was left waiting for Deku to change and be ready to leave the agency.
Bakugou had decided to change back into his civilian clothes once he’d reach his apartment. He needed those extra minutes to mentally prepare himself.
He’d reluctantly practiced with Kirishima and Mina what he was gonna say.
Mina had almost got herself killed by laughing at his efforts a bit too much but it had been worth it. Now he knew more or less what he’d say to Deku.
He’d tell him…
That he knew he probably didn’t feel the same way but he needed to tell him.
“Yeah, because I’m a selfish prick like that,” he thought out loud, kicking an innocent pebble away from his combat boots. Fuck it, he was going home. Who needed feelings anyway?
He was stopped by a big hand grabbing his shoulder.
“Kacchan, you waited for me!”
Deku had changed into his civilian clothes but something was different.
Instead of his "T-Shirt" t-shirt and his worn-out sweats, he was wearing black jeans (the fit was still questionable but an improvement is an improvement), a green shirt, and a cable knit sweater over it. He looked… not like shit, at all, and he was beaming.
“Kacchan,” he said before Katsuki could start on his way home before he made a complete idiot of himself like he suspected he would if he stayed a minute too long.
“What,” Katsuki said, trying his best to sound bored.
“Can I ask you something before you get on your way?”
Katsuki turned to look at his dumbass sidekick and for once he truly looked at him. Deku looked nervous and he was shifting his weight from one foot to the other. It was annoying.
“Just spill it, nerd! Some of us are tired.”
Deku seemed to be snapped out of whatever spiral of self-doubt he’d obviously trapped himself in and was now grabbing him by both his shoulders, his eyes burning with an intensity Katsuki had never seen before.
“Please go out with me!” he screamed, bowing his head.
A few middle schoolers that were passing by stopped and looked at the scene playing before their eyes. Katsuki stood frozen for a few seconds.
“Huh!” he screamed, feeling his face getting warmer and warmer.

It’d been a month since that embarrassing confession.
A month of Bakugou being slightly (read very) annoyed at tabloids for picking up on their new relationship status.
So, whenever they went to the movies or they decided to go running together or eat outside, some scummy reporter with an annoying quirk that concealed their presence was there, taking pictures of them.
Ground Zero blushes! Is the world coming to an end?
Sidekick Deku helps pro hero Ground Zero put on his coat.
Relationship expert breaks down Ground Zero and Deku’s body language. Will they last?
Those were some of the headlines that Bakugou unfortunately remembered.
Great, so his mind was now focused on that.
So far though, all of their dates had been outside either his or Deku’s place. Which was annoying as hell because it was obviously feeding those fucking hungry reporters with endless content but on the other side…
On the other side, Bakugou hadn’t felt pressured to initiate anything intimate with Deku and fuck if that wasn’t both a blessing and a curse.
But of course, his luck was bound to run out.
“Kacchan,” Deku exclaimed one day after work while they were both walking to get some coffee together.
It had been an exhausting shift. Night shifts were the worst on Bakugou since he was and had always been a morning person.
He yawned and stretched, bones cracking.
“What,” he said, noticing how even his voice lacked his usual bite.
Deku sighed and hugged him from behind, almost lifting him from the ground.
Great, Bakugou thought while blushing, keep feeding those vultures, they’re gonna fucking love taking a photo of this.
“Please come to my place tomorrow?”
Bakugou’s blush intensified. All of a sudden he wasn’t feeling so sleepy anymore.
“Fine…” he agreed, looking everywhere but at Deku. Fuck, he was probably looking elated or something.
When he dared look up, Deku was smiling fondly at him.
Bakugou gulped.
It was time.

Midoriya wasn’t nervous about Kacchan finally coming to his apartment.
No, he was having a meltdown, trying to somehow salvage what was left of the chicken pie he’d ambitiously tried to make before remembering his cooking skills were subpar on the best of days and downright non-existent the rest of the time.
So what if he couldn’t cook? Kacchan had said he didn’t want a perfect omega that cooked and cleaned.
Clearly, he thought, taking a look at his now ruined oven.
Kacchan arrived predictably on time, and looked… well, he'd never looked so good.
He was wearing tight jeans that left nothing (and he did mean nothing) to the imagination, a red silk-looking shirt half unbuttoned already and … was that… eyeliner?
Midoriya gulped visibly.
“Can I fucking come in now or are you not done staring at me?” Kacchan said in an irritated tone and Midoriya wordlessly moved aside to leave enough room for Bakugou to enter his apartment.
His boss turned boyfriend wrinkled his nose at the evident state of disarray of his apartment.
“Did you burn something?” he said, an amused lopsided grin on his face.
I think I’ll die, Midoriya thought as Bakugou approached the source of the burning smell.
“Yeah… thought I’d cook us something.”
“Yeah, no shit,” Bakugou said, still sounding amused.
Midoriya sighed dejectedly.
“Wanna order some pizza, instead?”
Bakugou turned around looking every bit as fierce as when he was in his hero suit, ruthlessly beating up villains.
He rolled up his sleeves and clicked his tongue.
“Fuck no, you shitty Deku,” he said before starting to rummage through his kitchen cabinets, “I’ll cook us something decent and you’re gonna watch me and learn, got it?”
Midoriya’s cheeks got warmer as he nodded, taking a seat near his boyfriend.
And so, Bakugou made the best, most delicious (yet spicy) curry he’d ever had the pleasure to taste.
Then they watched one of All Might’s old films. Bakugou complained about it but Midoriya could tell he was also such a fanboy of their childhood hero.
As time went by, Kacchan got closer and closer to him. Midoriya was itching to touch him, no longer paying any attention to the movie.
“Are you…”
He was interrupted by Bakugou forcefully kissing him. His lips were chapped and he was a bit too rough but it was fine. He grabbed Kacchan by his shoulders and deepened the kiss. Kacchan moaned and Midoriya could already feel himself getting hard. Kacchan looked every bit as excited as he was, though.
He reluctantly stopped their impromptu make-out session.
“Do you wanna…”
“Fuck yeah,” Kacchan said, cheeks tinted a lovely shade of pink, chest heaving.
Midoriya nodded, making for the bathroom where he kept lube and condoms.
When he returned though, he dropped both the bottle of lube and the condoms out of shock.
Midoriya blinked in confusion.
“What are you doing?” he asked, a bit panicked, watching Katsuki completely naked and on his knees, spreading his ass.
Katsuki, Kacchan… he was on the floor of his living room, next to his coffee table, chest pressed against the floor, ass up, spreading his cheeks like an…
“Will you fucking get on with the program, Deku?” Katsuki said, and though he sounded exasperated, his blushed neck betrayed his nervousness.
He arched his back in a very pornographic way, his lubed up hole clenching around nothing. Lubed up? When did he do that?
“Fucking Deku just fuck me already!” he screamed, turning his head back right at the same time Midoriya finally snapped out of his daze and made his way towards Katsuki.
He grabbed Katsuki's round, soft ass cheeks, and started massaging them, feeling Katsuki's breathing hitch.
Kacchan’s most private part, his delicious pink hole was right there. Midoriya was not about to pass on the opportunity to taste it.
“Oh fuck!” Katsuki screamed when Izuku started kissing his hole, right before pressing his tongue against it.
“You don’t mind, do you?” Izuku said, his hot breath hitting Bakugou’s skin and making it tingle, “that I’ve always wanted to have you like this. So ready to take me.”
Katsuki whined, then tried to muffle his voice by pressing his mouth against the carpet.
That won’t do, Izuku thought before leaving Katsuki’s puckered hole alone and grabbing his hair, pulling his hair back, making Katsuki scream in both pain and pleasure.
“Kacchan,” Izuku whispered softly against Katsuki’s ear, “When did you prep?”
Izuku pressed a finger against his entrance, penetrating him just with that one finger very slowly.
“Ah,” Katsuki moaned, his blush spreading all over his face until it reached the tip of his ears.
Cute.
“Before… I got here, dumbass,” he said, eyes rolling back on their own once Izuku added a second and third finger almost instantly after that.
He started scissoring them, trying to find that special place that would surely make his Kacchan lose his mind. When he finally found it, Kacchan moaned loud.
“You’re such a good alpha,” he praised him while licking behind his ear, pressing his fingers against Katsuki’s prostate, seeing how Kacchan’s dick was already leaking precum.
“Deku, fuck me, fuck me!”
At that moment Izuku realized he’d never been able to deny him anything.
He took his cock out of his pants. It was extremely hard. He pressed it against his alpha’s entrance.
“Ready?” he warned and just when Bakugou was about to scream at him in anger, he started pushing the head in.
“Ah!”
Oh, it felt so good.
Midoriya had done it with other Betas and the occasional Omega, but nothing could compare to Kacchan. His insides were so tight but also soft, the perfect place to bury his cock.
“Ah, yes, yes, you’re so perfect,” he said, picking up his pace almost instantly.
Kacchan whined, hips snapping back, trying to meet his desperate thrusts.
“Why didn’t you wait!”
Izuku kept on fucking him desperately, grabbing Katsuki by his waist and marveling at how his big hands almost circled the entire way around it.
“You can take it, alpha, you’re so good for me,” he said, fingers pressing, searching lower for that place where he might feel his dick pulsing inside of Katsuki.
"Ah, stop doing that, fuuuuck!" Katsuki said once he could feel the outline of his dick. Well, that was hot.
His pace increased, and yeah maybe he was too excited to control his quirk, sue him.
Katsuki was almost incoherent at this point, breathing harder, hips moving back, trying to meet Izuku’s now brutal pace.
Izuku detached one hand from Kacchan's small waist, in search for his alpha’s cock and when he found it, he grabbed Kacchan's already forming knot and squeezed.
Kacchan screamed and started cumming all over his carpet. Izuku kept on fucking him, feeling himself get closer to completion.
Just when he was about to, Kacchan turned his neck, showing his gland to Izuku.
“Do….it, Deku…”
Betas don’t have fangs the way omegas and alphas do but when his teeth met Kacchan’s gland the skin broke.
His mark was imperfect but it was there, a clear proof of his claim on Katsuki, an alpha.
He felt Kacchan clenching around his cock, squeezing the cum out of it and inside his hole.
Izuku grabbed Kacchan’s knot again and kacchan cried, still cumming in waves.
When he got off Kacchan’s sweet greedy hole, he saw a bit of his cum drip out of it.
“No,” Kacchan whined and trembled, seemingly too exhausted to get himself off the floor.
Izuku grabbed a bit of his cum that was dripping out of Kacchan and pushed it back inside as far as his finger would go.
The likelihood of Kacchan (his alpha, he thought looking at his claim mark) ever having pups was close to zero.
The likelihood of an alpha ever submitting to a beta was also close to zero.
Izuku carried Katsuki to bed before wrapping his arms around him and drifting off to sleep.
