[It was normal for you to start presenting as you started highschool, therabouts. But Izuku...he hadn't yet. He was a late bloomer, as he seemed to be with everything, which made him wonder if maybe he wasn't just a Beta or something after all.

Ever since they were kids though, Katsuki would drill it into him that he'd only ever be an Omega. He was too wimpy and weak to be anything but. So why hadn't it shown up yet? Surely it would have by now, especially now that others are presenting all around him, Omegas experiencing their first heats before being put on supressants, and the same with Alphas and ruts.

But there was no change for Izuku. At least not until second year.

It had been a normal day, or so he thought. No abnormalities, nothing really out of the ordinary as he entered school grounds and headed towards his homeroom class. Once he actually made it inside though, something strange hit him. All the people he could normally smell throughout the day...their scents had amplified tenfold. He could immediately scent each and every one without having to look at them.

Alpha. Alpha. Omega. Beta. Omega.

He stepped past the threshold into homeroom, assaulted by too many smells and too much noise. He felt...hot, and overwhelmed, bringing his sleeve to his mouth for a moment for a breather as he sat heavily down in the seat behind Katsuki's. He hadn't come in yet...]

[Katsuki, for fuck's sake-

Izuku just sighs, licking over the mark a bit more as Katsuki continues to gripe about it.]

You know I would have stopped if I could.

Tch.

[Is his immediate reply, jutting his lower jaw out in a pout because he simply doesn't have anything else to say. It's too late now and whether Katsuki likes it or not, they're mates.]

....whatever. Guess it wasn't the worst sex I coulda' had.

...yeah? Was it really okay?

[It doesn't...really matter, but.

Also it does.]

Shut the fuck up, I didn't say that so you could start getting a big head!

[He says that with a small smack to the side of Deku's head, his cheeks flushed all the way to the tips of his ears.]

It just wasn't the worst, got it?!

Ow! I-I'm not, I'm just asking...

[It's kindof important to him, okay. He doesn't like to think that he maybe ruined Katsuki's first time because he was awful, or something. Not that either of them have any experiences to compare it to, or anything.

He sighs, his brows furrowing as he feels that knot steadily receding.]

...I'm glad, though.

[Bakugo lets out an annoyed sounding sigh, turning his head so he doesn't have to look Deku in the face anymore. At first it looks as though he's done with the conversation, perhaps just silently waiting now for the swelling of Deku's cock to completely go down.

But he does speak up, eventually. A bit quiet and grumbly.]

....what about you?

[Katsuki is a jerk but even he cares about both of them feeling satisfied.]

[Oh...

Izuku blushes, keeping his gaze angled sheepishly elsewhere.]

I-it was great.

[He thinks he would have enjoyed it more if his first time wasn't in the school bathroom, but you know.]

Good answer.

[Katsuki snorts at the other teen, before twisting his hips a little to reach behind and feel the base of Deku's cock. It feels pretty small now.. he could probably slip off if he worked on it, and so he does. Leaning forward against Deku as he tries to coax his penis out of him.]

I would've-- [He winces, as he feels the knot finally slip out, his breath catching in his throat for a few seconds before he has to pant to get air back in his lungs.]

...I-I would've killed you if you said it was anything less than great.

[He threatens that, as he tries to ignore the wet semen oozing out of him now that Deku's no longer keeping it all in.]

I don't...ah- think it could have been anything le-less...

[Like, Katsuki doesn't know this, but Izuku...sort of already has a thing for him, so. It would have been amazing even if it was the worst sex in the world.

Also, the feeling of his cock popping out of Katsuki is...uncomfortable, but probably not as uncomfortable as Katsuki is.]

Tch..

[Is Katsuki blushing at Izuku's compliment? It's hard to tell, but all signs point to: probably.

Either way, he slowly starts to push himself off of Deku finally, wincing when he puts weight against his feet.]

I'm goin' to the nurse's. Don't follow me, got it?

Mhm...

[He wasn't planning on it. Not like he has time right now anyway, his whole face and neck are bloody from biting Katsuki, so he needs to clean up some in here before he's caught with his pants down. Literally.]

[Good. It makes things less awkward, when Katsuki leaves to get his body checked on by the nurse. To make sure everything is okay.

...it's. It's not. Not really. It takes a couple more check ups to be sure of it but sure enough.. Deku had gone a little too far with Katsuki. A little too far, in a way that cost more than either of them were prepared for. And it shocked Katsuki to his bones when he was told he'd be having Deku's kids, he didn't know how to properly absorb that information so he ignored it as long as he could.

...well. About a month. That was about how long he could keep quiet about it, before the thoughts and fears surrounding the situation started to suffocate him.

That's why, one night at around two in the morning, Deku hears a soft knock on his dorm door.]

[It's maybe been a bit of a Problem that Katsuki has more or less been completely ignoring Izuku for a month, because...they didn't just have a random fling in that bathroom. Izuku claimed him, they mated, making them actual mates now. Which meant that not having any real contact with his Omega- no ability to scent or even stay in the same room- had been taking a toll on Izuku. He'd been more irritable lately and easy to tick off, and it showed with his friends. They could tell something was off, but there wasn't much they could do other than gently let Izuku know he could talk to them if something was wrong.

Of course, he never did. He couldn't. They knew he'd presented finally, so maybe it was just the afteraffects of dealing with the new hormones. Izuku, such a meek and shy person, becoming an Alpha had been totally unprecedented, after all.

Izuku had finally gotten to sleep when he's jerked awake by a knock at his door, a low growl rumbling deep in his chest as he throws his blankets off and gets up, stomping to the door. He pulls it open with eyes still half shut.]

What-

[...and then he blinks a time or two, realizing who it actually is standing there.]

...o-oh.

[When Deku throws that door open, growling in a deep commanding voice, it actually gets Katsuki to flinch for just a split second. Deku being his Alpha means his anger... is a bit more terrifying to Katsuki than anyone else's. But it's quick for him to shake off that momentary surprise, an annoyed expression set on his face and he steps forward into Deku's room, pushing him aside with his elbow as he does.]

"Oh"? That's all you've got to say?

[He scoffs, and turns around so he can lean his lower back against Deku's desk and so he can look at him, as well.]

[Izuku closes his door as Katsuki unceremoniously barges his way in, his gaze slightly narrowed even though every instinct has left him feeling happy to finally see his mate again...]

It's not like you've spoken to me for a whole month. What else am I supposed to say?

Oh, don't start bitching-- it ain't like you own me!

[Katsuki snaps that at him, folding his arms over his chest with his chin jutting forward in a snarl.]

We fucked once, that's it!

[Izuku's gaze narrows further, his expression darkening slightly at that response.]

We mated.

[It's a firm correction. They fucked, yes, but it would be different if that's all they did. Katsuki's neck is still scarred from it, after all, so he's probably been having to keep it covered somehow.]

[Just the mention of it is enough to get Katsuki to reach up to the scarred tissue, calloused fingers running over the fresh scars in the shape of his mate's teeth.]

...did you expect me to get all lovey-dovey with you now that we're mates?

I expected you to not ignore me for weeks.

[Comes Izuku's low reply, the backs of his teeth grinding together as he holds himself back from saying something he might regret.]

I know you must have been feeling it, too.

["It" being the pain of being apart. The instinctual tug to want to at least be near, especially for those first few days.]

So what if I have? You just-- you fucked me against the fucking door and expect me to be all over your cock immediately after?!

[Katsuki almost can't believe the nerve of this guy. He's gotten so confident just because he's an Alpha.. ugh. It's so infuriating but at the same time it gets Katsuki riled up in a way he loathes.]

I was giving myself time to get fucking used to this shit, asshole!

Stop putting fucking words in my mouth!

[Izuku fires back, moving off the door and a step or two closer to where Katsuki is still leaning on his desk.]

You don't get to come in here and talk to me like that! You're acting like I took advantage of you!

[Katsuki is immediately on the defensive, straightening his back to try and seem taller-- more intimidating than the Alpha raising his voice.]

You didn't, but you don't get to act pissy 'cuz I haven't been eager to talk to you after that!

I came here because we haven't talked, but I can easily leave if that's what you want!

I'm "pissy" because it hurts!

[Izuku hisses through gritted teeth, trying not to raise his voice anymore because he knows he's at risk of waking his dorm neighbors if he does.]

It hurts for me to be apart from you right now, don't you get that?! It doesn't have anything to do with how you or I feel, it's because I marked you.

[Katsuki is sort of his responsibility now. To guard, protect, and care for. Kindof hard to do that when he won't talk to or acknowledge him, even if he has a valid reason for it.]

[If Katsuki felt bad, he doesn't show it. There's no remorse on his expression, in fact he looks even more annoyed at Deku's confession.

But he doesn't argue or mock him, no. Rather than making a bigger deal out of this which he very easily could, Katsuki steps forward towards Deku and grabs the collar of his shirt. From there he pulls his face close, and wastes no time pressing his lips against the smaller boy's. Maybe it's an apology in his own way for ignoring him.]

[Admittedly, Izuku wasn't expecting that at all. In fact, he was braced for a punch more than he was a kiss, so the surprised grunt he gives is more than just involuntary. He stiffens as Katsuki holds tight to his collar and kisses him, Izuku's expression tight until a handful of seconds have passed, enough for him to slowly relax. This is what he's been wanting for weeks, after all...more than, even. He just wanted to be near him in the first place.

He stands a bit straighter, kissing back carefully even though he's still not entirely sure how to do it right.]
