Omegaverse

Students find out their secondary sex during high school exams. Alphas and Betas can do whatever they want (par the course) but if the school accepts an omega, that student has to work as a cumdumpster for the school in lieu of paying tuition.

Guess what Deku presents as?

Everything goes as canon – he’s worried more about how he didn’t get any points in the exam rather than what his blood test would show because his parents and their parents are all betas so he should be a beta too, right?

And then the video came in and he’s so happy, Inko has to check his paperwork to see what he presents as.

She stops, bites her lips as she starts crying again, but not with the joyful tears of just a few moments ago.

“Izuku, sweetie,” her voice wavers. “Did you read your results?”

Deku takes the paperwork and his world shatters once again

He’s an omega – a state mandated cumdump to any and all depending on his school/class. Anyone who presents higher than him can use him as they see fit until he has an alpha (unless his alpha wants him to be fucked by everyone). The only thing worse would have been if he didn’t get in.

At least as a UA omega, he has the right to refuse anyone other than his classmates and his teachers – anyone else who tries to force him into sexual situations can (and will) be punished by law if his teachers and classmates don’t get to them first. He’s assigned as 1A’s only Ω.

That night when he meets All Might, Izuku sobs and apologizes – of course All Might doesn’t want an omega as a successor, he can give One For All back so he can find someone better, more like All Might because who would take an omega hero seriously?

And instead of doing the “smart” thing of taking it back, All Might hugs Izuku instead. “There’s nothing wrong my boy.”

All Might might present as an alpha but Yagi is a beta, and while laws weren’t as bad when he was in school, he has friends who are omega and heroes. Yagi says he will help Midoriya anyway he can, to make him the best hero he can. And if he wants to hide he’s an omega he will help, show him the tricks to fool people. If he wants to be the first openly omega hero, he’ll help too.

And Izuku starts crying (“We are going to have to work on that Midoriya-shounen”) but he can’t stop because he’s so happy and grateful and…

“Touch me, please.”

He’s not used to having others touch him and if he’s to be an omega and a hero he needs to get started right?

All Might obliges; the two leave the beach with a hand on his shoulder, fingers brushing against the sides of the new black collar Deku needs to wear.

“It looks good on you, you’ll look even better once you get UA’s insignia against your throat.”

Those words make Deku heat up in a good way

It’s a secluded area. All Might runs thin fingers through Midoriya’s hair and across face, resting against his lips and pulling a whine out of the boy. But he doesn’t do much more than touch.

“Experiment a bit my boy and come back if you want.”

Experiment huh? There’s only one person…

There’s still a week or so of middle school. Deku keeps his jacket collar closed to keep his omega status secret but he tells Kacchan when he corners him.

“I’m an omega and new to my quirk but I’m going to be the best and be worthy of an alpha as awesome as you!”

(Because of course α!BKG)

That sounds like a challenge to him.

“There’s no alpha as great as I am you fuck and I’ll show you who’s worthy!” And then he blinks cause that was lowkey a proposal but who the fuck cares. He’s an alpha and any omega would be lucky enough to have him. “Prove you’re not useless and maybe I’ll give you my dick.”

(And even before Deku presented he had wet dreams about Kacchan, to have that fierceness and drive directed at him. It’s just dreams but the chance they can be reality…)

Deku licks his lips. “Show me what you got when classes start”

(When the results come in and Deku comes back from Recovery Girl with a hand in a brace and a lot more male omega literature than he expected, Katsuki sneers and says his ass got lucky since he wasn’t gonna ruin it now)

---

I just really want the rest of 1A to use Deku as they want, cockwarming between (and sometimes during) classes, licking pussy during breaks, eating cum during lunch, etc.

If someone does write this I kinda really want Enji to be an omega (the friend Yagi knew who was both hero and Ω) and helps Deku through heats etc

He’s still pretty shit at being a dad but he is surprisingly good at peptalking Deku to Shouto’s deadpan delight.

I’m not sure if Rei is an α or Ω – both have their perks from a story standpoint.

Enji’s quirk is powerful and his family had money which kept him from getting pulled into being a cumdumpster too often in high school. Yagi also helped to Enji’s ire.

---

I really like the idea of omega!Enji coaching Deku as one of the few active omega heroes (although he masquerades as a beta or alpha). Showing how to snarl like others, the best kind of suppressants and how to deal with heats.

Shouto is weirded out; his dad can parent another kid better than he can parent his own.

“That guy is a failure as an omega.”

Enji is in earshot – “that’s why i’m working with Midoriya.”

“…guess that makes sense”

Midoriya does not get the Todoroki’s they’re a different breed.

Dynamics of the rest of 1A

α: Baku, todo, Uraraka, Toko, Jirou, Momo, Hagakure, Sero, Shouji, Tsuyu

β: Iida, Mineta, Kiri, Kami, Koda, Mina, Aoyama, Ojiro, Sato,

Deku is overwhelmed by how much the class enjoys his presence. Even outside the sex.

Not that he doesnt like that too, wow, he never thought sitting on a cock for an hour would be so comfy!

α×α is actually pretty common as is β×β and α×β – omegas are actually fucking rare so while everyone will use Deku at some point or another (I really love the idea of Jirou using Deku to keep her cock warm while sounding his with her jacks) but will definitely fall in love with others

Which on one hand, he loves his class/friends but on the other, everyone is falling in love around him and he’s getting sex and friendship but no one who really wants to be with him. Forever.

And maybe they’re young but still.

He wants to be with someone. Eventually.

But hes not gonna stop having sex.

Deku is going to be the best hero ever and he is going to learn how to use being an omega to his advantage (Within the law. Mostly).

Tsuyu likes playing with Izuku with her tongue and cock during their academic classes. In another universe it would be sexual harassment but here, Tsuyu using her tongue to play under Deku’s collar is foreplay.

Monoma makes fun of Deku during the sports festival because of his gender. Bakugou decks him during the 2nd round because of it cause he’s been more protective of the him.

“Only our class can make fun of Deku you shitstain!”

1A has gotten into pack mentality  early on and doesnt take kindly to threats to it. Especially their omega. 

You can probs blame USJ for that actually – they banded together to not die and their little omega fucked himself up to save people and –

“It was just really manly.”

Shinsou tries to use his quirk and omega pheromones in round three. Which uh. Didn’t work as planned and instead worked up Deku’s heat early.

The two bond afterwards because they’re two omegas wanting to be heroes and unwilling to hide the fact.

---

Stain is a chauvinist pig who looks down on omegas so he doesn’t think Deku can be a hero.

“You have a hero’s soul, but a body that is meant only to be a victim or a damsel in distress.”

This pisses off Iida a lot because Deku is more than just his status.
