Into the Omegaverse

Aomine ~Aggressive~

I'm testing the waters out with this one since I'm new to posting on Wattpad, so here's a shorter and tamer fic I wrote

Warning: Sexual themes
————————————————————————

Being a beta and coming from an all beta family left you in the dark about omegas and alphas. Of course you knew the basics about them, but betas typically mated and married other betas seeing as how omegas and alphas were typically attracted to each other more commonly. So because of this the all beta school you attended never really touched on the topic of omegas and alphas, all you really knew about them was that omegas were submissive and alphas were dominant. You also were never really interested in learning more because you always saw yourself getting married to a beta, like your family always said you would.

So when you met Aomine Daiki, an alpha, you were introduced to many new things.

For example, how possessive an alpha was. He would constantly scent you (which you found pointless, because you went to an all beta school). He was always jealous so when you two went out he made sure you were always by his side. And you weren't really sure if it was an alpha thing or an Aomine thing but he had a pretty high sex drive (not that you complained).

Aomine was also introduced to many new things as well. Like how you didn't depend on him like an omega would. He figured out scenting you was difficult because an alphas scent didn't stick to a beta the same way it did to an omega. And he very quickly found out his commands didn't work on you. You didn't have that instinctual need to listen to an alphas commands, so whenever he used that tone with you, you just scoffed (on the bright side it taught Aomine how to ask you for things nicely).

He also wasn't used to someone not knowing how he felt by how his scent smelled. You weren't able to tell how he felt unless he told you, which lead to many frustrating moments for him in your relationship.

Like now.

You had gone over Aomine's house to hang out, you were currently laying on your back on his bed, with your head pointing towards the footboard playing on your phone. While Aomine laid against the headboard, trying to read one of his magazines. Keyword: trying.

He never paid attention to his calendar, so he wasn't expecting to feel the beginnings of a rut. Whenever he tried to calm down and pay attention to his magazine he would find himself staring at you, finding you way more interesting than the models. Still wearing your uniform skirt, his gaze would start from your calves and his eyes would trail up your bare legs hoping for a peak under your skirt.

"Hey, pay attention!," you yelled throwing a shirt from his floor at him.

"What?" He grunted, throwing the shirt back.

"I've been trying to get your attention for like 5 minutes, what's up, you've been staring at me like all night." You sat up.

Aomine sighed, "You should probably leave," did Aomine want to take care of his rut, of course, but he didn't want to scare you off, his rut would just get stronger, and he didn't want to freak you out by getting all aggressive and rougher than what you were used to.

"What? Why?" You asked confused.

Oh how he wished you could've known just by his scent, "It's, uh, my.. rut."

"What's a rut?"

Aomine looked at you incredulously, "Did you really just ask me that?"

"Yeah? Well— I know it's an alpha thing and has something to do about mating, I think my health class touched on it briefly but I fell asleep."

Aomine rolled his eyes and nodded, leaning his head back against the headboard, "Do you know what it means when an omega is in heat?"

"Yeah, they get super horny or something."

He rolled his eyes at your bluntness, "Yeah, you could put it that way, well a rut is like a heat but for alphas."

"Oh," you muttered in realization.

It was silent as he expected you to get up and leave, but instead you asked, "So you wanna fuck?"

He rolled his eyes again at you, "No shit, I wanna fuck, but I'm starting a rut so you should probably go before I jump you."

"What if I don't want to." You asked, crawling closer to him and sitting next to his outstretched legs.

Aomine looked at you for a few seconds, contemplating his options, but before he could speak you said, "I'm kinda surprised, why would you want me to leave during your rut. It's not like it would be our first time."

"Because it's different, they make alphas more aggressive than usual," Aomine tsked, not looking at you anymore. His self control was diminishing and he really was close to jumping on top of you.

You scoffed, "If an omega can handle an alphas rut, then I think I'm more than capable to handle my alphas rut as well."

It was getting to be too much. Your words only making it worse and unknown to you, your scent changed, no where near what an omegas would be, but it was still there. It was subtle but affected Aomine greatly.

He gripped the magazine in one hand and covered his mouth and nose with his other hand, "(f/n), I'm giving you one last chance to leave."

You swung one leg around him and straddled his lap. Instinctually, his hands immediately gripped your waist and pulled your body flush against his.

"Daiki, I don't know if you've noticed," you smirked, "But I like aggressive, why else would I still be with you?" You giggled.

He suddenly flipped both of you, so that he was above you and you laid flat on your back, "Says the girl who still has a limp from last time," He muttered lowly against your ear before biting your earlobe.

You wrapped your legs around his waist and grinned wickedly at him, "But I never complained, did I?"

He growled lowly, lips latching onto your neck, "Fine, but no whining if you can't walk next week," he muttered, pushing his shorts down and flipping your skirt up.

It was true that you learned many new things by mating with an alpha. Like how helping an alpha through a rut meant nonstop sex for three days and that you'd be too sore to do anything for an entire week after.
