Alpha!Katsuki who is so agitated and aggressive although protective of Omegas even if their scents bother him. Roughly keeping them at arms length and openly snarling or grimacing at their scents as he saves or even just interacts with them.

Then there is you, an Omega who acts like an Alpha. Your scent is as strong as an Alpha, you're just as aggressive and have plenty of scars on your throat to show it. When someone thinks of a "traditional" Omega they think the opposite of you. In fact most people already assume your subgender is Alpha, you never correct them.

But you're not, you're an Omega. One with conflicting feelings of wanting to be soft and cozy but can't bring yourself to be less than combative. One who has several nests around your home in all your most comfy spots piled with blankets and stuffed animals you treat with care. An Omega who's given in and stolen her boss' smokey caramel shirt after a workout despite saying you can't stand his scent. An Omega who can't resist the urge to shove it into the nest on your bed as slick gathers between your thighs, naughty fingers toying with your throbbing clit through the fabric of your underwear until you're cumming so hard and so often you're panting. Borderline throwing yourself into a heat over his stupid sweaty shirt because his scent makes you feel safe, soft.

It's tempting to call out the next day but truly you were his front line, he hired you because of your bad attitude and snapping teeth. Because you could and would stand up to an alpha three times your size that demanded to see Katsuki even when they didn't have an appointment. You could handle yourself and you've proven it. Plus what Katsuki will never admit out loud is that he likes the way you smell, loves it. To him it makes sense he's only ever bedded two people and both were Alphas like he thinks you are.

Yet when you come in reeking of distress, shame, and arousal Katsuki finds his body moving on its own.

Pulling you by your lower back until your pelvis is flush with his before you can protest even as you lean away and accidentally expose your throat to him. His nose goes straight to your scent gland, inhaling to make sure it's you that the distress is coming from. The arousal

"Bakugou." You try to push him away but as the number one pro he's much stronger than you, not to mention his scent gland is right by your nose now. His spiced scent sweetening in an attempt to make you relax, pheromones he doesn't realize he's releasing as you fight your body from going slack in his hold.

On lookers stare and when bromine eyes meet them they flare. Lifting his face so they can see him bare his teeth as he pulls you into his office.

"Ya outta suppressants?" He growls and all his voice and strength do is spur on more and more of that arousal that wafts off of you in waves. Sweet floral spice that makes him dizzy as he tries not to get hard. He should let you go, he should step back, but he can't peel himself from your body. You feel good in his hands. Soft, round.

"I don't take any."

"Ya can't go into a rut in my office." He snarls but his lips are resting against your collar bones, "I've got extra in my desk."

"It won't be a rut." Your skin feels hot, so hot and with Katsuki smothering you it's only worsening the effects, the shame that burns when you admit out loud to your boss that you never corrected on what you are, "It's a heat."

Suddenly his massive body is rigid, you can hear him swallow thickly three times before you feel the hardness of his fat length against your leg

And that's enough to send any Omega nose first into a long overdue heat.

@kweenkatsuki-fics sorry it's so long 😭
