Omega Bakugo confuses the fuck out of everyone bc he likes to cross scent with everything. Alpha shower gel because its strong enough to mask the scent of his gross quirk sweat, omega shampoo and conditioner because fuck 4-in-1 alpha hair products, alpha

deodorant bc once again, gross quirk sweat, omega body spray because it's the only thing offering a scent profile that fits to his own omegan scent. The only things he doesn't care about are body lotion and hand moisturizer. He tends to just take scent neutral stuff for that, or

even scent suppressing stuff, because he gets self-conscious about his skin getting smelly over the day.

So naturally, nobody knows what the fuck is going on with him, and Bakugo doesnt bother to explain as long as nobody asks. Its not anyone's business anyway.

Except Deku's.

Its logical - that he knows. He's been exposed to Katsuki's scent since they've been /babies/. He's so used to his scent he won't even detect it anymore when he comes over to his dorm room or visits the Bakugo house. But he does detect his mood swings and pheromones, most of the

time subconsciously.

Not that Katsuki cares. It doesnt matter to him that the nerd knows whenever he feels needy, happy, sad or gives him used clothes bc he felt him getting upset about something.

It doesn't matter.

But he's still grateful for it whenever he's in preheat and

Deku just - won't leave him alone.

Katsuki's pretty sure Deku doesn't even realize he does it. At this point it's just ingrained into his stupid alpha brain. He'll sit next to Katsuki during lunch and won't leave his side, he'll scent the air a little more when he's close to

him, he takes his hand when they're walking and sometimes even puts his arm around his back or waist when they're sitting in the common room in the evening.

Katsuki would like to say he's annoyed with it, but goddamn, he's just an omega like every other omega. And since no one

even knows what his subgender is and that he could potentially be in preheat, Deku's the only one tending to him.

And not gonna lie, that feels kind of /really/ nice. Kind of like - he's Deku's - Deku's his -

Ugh.

No, he doesn't care. They're just childhood friends. That's

just what childhood friends do for each other.

At least that's what Katsuki tells himself until he goes into heat in the middle of the common room and Deku's the only one that realizes.

It's just the beginning, and Katsuki doesn't even realize it /himself/. They're watching

a film on Friday night, and his friends have forbidden him to flee the scene, even made him promise to not ditch them in the middle of it like usual. He was grouchy the whole time he waited for the film to begin, until Deku sat down next to him and pulled his head against his own

shoulder with an arm around his back. He was still sulking after that, but at least he was quiet about it now.

It all went well for the first half of the film, and just as Katsuki started to get hungry for some sweets and couldn't decide between falling asleep or getting up to

get some, Deku pulled his arm away like he got burned (which only startled Katsuki back to full awareness bc he was on alert, not because his alpha just rejected-) slapped his hand on his own neck aggressively like he remembered to do something, and then immediately went behind

Katsuki's back, under the blanket they had across themselves, and -

and right down Katsuki's sweatpants, cupping his hand smack dab across his /crack/.

Obviously, Katsuki's first instinct was to scream.

But before he could even think about it, his body curled into Deku's

shoulder painfully, pressing his face into the bony thing almost to the point it hurt, in what was unmistakably the first cramp of his heat hitting.

That fucker. That goddamn fucker knew before even Katsuki himself! /How?/

Katsuki would be angry if he wasn't just in massive

pain.

It takes about 15 seconds for the cramp to subside, and Katsuki knows; the first wave of slick should hit right after. Deku has masked the oncoming scent well enough for now, with his heavily scented hand /blatantly/ over Katsuki's entrance, but it won't hold for long.

"What the fuck?", Katsuki hisses at Deku, completely embarrassed out of his mind but also very grateful because this stupid alpha's closeness is actually /helping/. He cannot believe this just happened, what is he going to do, what even is this? How are they gonna get out of this

without embarrassing both of them? There's no way!

- Deku's being Deku and brings him upstairs
- Deku's being brave and brings him upstairs
- Deku's being bold and they stay downstairs
- Deku's being possessive and they stay downstairs

{ thank you all for the overwhelmingly big support on this thread. I can't express how happy that made me. next time I'll make the poll longer so everyone can vote! }

{ remember: likes, rts and qrts are always appreciated! have fun reading! }

Deku looks back at him, with an equally embarrassed and shocked expression, but at least there's also the age old stupid Deku determination mixed in. It's a reassurance that this situation isn't entirely a lost case yet, albeit not a big one.

"So what now, idiot," Katsuki

prompts again, when the mortification of his goddamn /ass/ slicking up right against an alpha's hand sets in and Deku seems to not bother making another move at all. "What's the next fucking step?"

Deku makes an aborted noise, his face staying slack while he goes beet red.

"Uh. I don't know. I uh, that was my first instinct. Wasn't really thinking ahead when I did it."

Great.

Absolutely impeccable.

(And that's the alpha his omega had chosen?)

Katsuki wants to punch him, but that would be counterproductive in this situation. Probably.

Hopefully. Its the only reason keeping him from doing it.

Katsuki lets out a pained noise, trying to ignore the fucking /hand/ on his /ass crack/ while he thinks.

"So you just expect me to, what, stay like this? Huh? I'm in fucking heat, think of something, you braindead

knothead!"

That finally seems to kick in some common sense in Deku. Though, not the right kind.

Katsuki can just barely smack his own arm to the back in time to grip Deku's wrist and keep it where it is.

"Don't you dare pull out your goddamn hand now, after you got slick on

it like an idiot. I'm not keen on every extra here knowing what my - what I smell like."

There is a baffled pause between them, where they just respectively stare at each other like the other just went completely insane.

Katsuki feels another gush of slick slide down inside and

immediately feels like crying. He cannot /believe/ this is happening.

"Alright, alright, I, uhm - "

Deku keeps on stammering until his hand gets soaked with the new wave of slick and immediately gets silenced by the overwhelming feeling of /fear for his goddamn life/. His eyes

get really big then, for a second, before he finally regains some semblance of sense and uses his quirk to get them out of there.

It's messy, but it works. It's the furthest from subtle, Deku bundling Katsuki up in their throw blanket and bunny hopping them out of the common

room with One for All lighting them up, but it works. Katsuki won't complain, as long as he doesn't have to experience his first wave of heat hitting in the middle of his class members.

So. There they are. Katsuki in Deku's arms in the middle of the nerd's bedroom, one of

Deku's hands weirdly stuck in a chaotic cocoon of throw blanket and slick sweatpants, the other one completely holding Katsuki's whole body and weight. (No, that's not kind of hot just because the idiot's strong as fuck now. Nuh uh. Katsuki refuses.)

"Uh, uhm, uh, Kacchan - "

"Let me down."

"Ah, ye, yes! Of course, uhm, how, how do I - "

"Just - fucking. Pull your goddamn hand. Out of my underwear. And put me down."

Katsuki is holding onto the last figments of his nerves. Not only because he's utterly frustrated by this situation, but also /his

heat is literally about to take over his goddamn body and he doesn't know how much longer he'll have to kick Deku's ass/.

After some grueling seconds of Deku fiddling around with the chaos of blankets and clothes, he's finally able to pull out his hand and set Katsuki on his

own fucking feet again. He immediately goes to rip the blanket from around him, discarding it onto the floor and pulling up his sweatpants so they sit right. He's already a little sweaty and the tips of his ears are certainly NOT red from embarrassment because -

his heat and slick scent start permeating the room.

Goddamn, he's standing in the middle of Deku's - /alpha's/ room, maybe seconds away from his knees buckling and presenting. Preheat's literally at his neck right now trying to convince him to stay here and /nest/.

What is he supposed to do?

what happens next?

- Deku gets curious and licks his hand
- they argue about what just happened
- Deku's alpha instincts set in
- Katsuki's omega/heat instincts set in

https://ko-fi.com/baltic_breath 

It's quiet between them for a few seconds, in which Katsuki thinks he might actually be hallucinating and dreaming up some weird ass shit. Maybe he got hit upside the head too hard last training session with shitty hair.

Maybe - ah, no. No, that cramp feels a little too real.

Katsuki regrets life.

"Ka- , om -, sl.. slick.."

It's almost laughable, what Deku stammers to himself sometimes. Even with their friendship renewed, making fun of it is one of Katsuki's favorite pastimes. This time though, he doesn't even /dare/.

Deku has his hand lifted

a little, palm turned up, fingers closing and spreading slowly, and /fuck, Katsuki knows what he's doing/. He sometimes does it too, after a particularly rough heat wave or after fingering himself, but, /God/, this is Deku! Deku is inspecting his slick!

"Fuh, fuck, stop that -"

Its embarrassing how small Katsuki's voice sounds, so he instantly decides against finishing that sentence and shuts up instead. He watches in mortification as Deku lifts his hand more, holds it against the light shining in through the windows and continues spreading his fingers,

even going so far as putting his thumb against the pads of his fingers and feeling around the slick between them.

Katsuki chokes, but his omega purrs.

"Hm, I wonder how Kacchan's subgender and instincts influence.. mhm.. maybe similar to hum, hum.."

Deku continues to mumble,

but his sight isn't as distant as it usually is when he gets into his own head like a maniac. It is still very much focused on the slick glistening on his scarred, fuck up, rough hands, like he is planning something big with it. Katsuki is /not/ a fan of that.

Deku lifts his

hand even more, closer to his face, and Katsuki's hands explode by instinct. He's /so embarrassed/, there's no way Deku's trying to - that he wants to -

"Don't, Deku, don't. Don't you dare. Izuku -"

At the last second, Deku's gaze sweeps over to Katsuki, eyes big and bright at

being called by his actual name, but not even that could deter him from his path of absolute destruction. It is already too late by that point, and they have to stare each other dead in the eye as Deku's hands connect to his mouth and his tongue darts out to lick across his palm

as well as in between and around his fingers.

It takes Katsuki absolutely way too long to look away. He can't even do it without whining out a soft "oh my god" which would've embarrassed the fuck out of him in any other situation if his omega wasn't going entirely fucking feral

in his head right that second.

Deku, Izuku, his /alpha/ is licking Katsuki's own fresh slick from his hand. Just like that.

Katsuki can basically feel his pupils dilate. Deku's pupils have been dilated for a few minutes already too, he realizes.

(How long until one of them

breaks? How long until their instincts take over?)

Katsuki throws his hand against his eyes, trying to shield them and relieve himself of the tension building up between their gazes. He even wants to turn away, maybe walk over to Deku's bed or desk just to distract himself, but

there's a small growl coming from the alpha in front of him before he can. It's not a big or intimidating growl, just a little warning. It makes Katsuki unable to turn his back on his - on him.

There's even - Katsuki can't believe it - he lets out a little omegan sound. He has

never really done that before. Not even when he was with his pack, not even when they were grooming him or letting him groom them. But there it is, something along the lines of a trill or a chirp, a reassurance to his alpha that he had Katsuki's full attention.

Its truly embarrassing. It shocks Katsuki out of his stupor and makes him realize how far down the road of his heat he already is. To counteract, he reacts with anger. As usual.

"Wuh, why did you fucking do that shit?"

Deku looks stunned.

"What?"

"Licking your goddamn hand!"

Deku stammers around helplessly, almost looking a little dejected.

"But. But it's Kacchan's."

Katsuki doesn't know what to say. His omega is roaring in his ears.

"Also, Kacchan smells really nice. Needed to know if he tastes as good."

It's over for him. It's goddamn fucking

over for him. Katsuki spent months, maybe years, trying to keep his omega in check, and this is was ultimately makes him break.

What a way to go, honestly.

"/Alpha/."

(With both parties' instincts at war..)
