My alpha

Katsuki?!?

He pulls me to the courtyard as he yells at a green-haired omega for suppressants
"Take these" he says and I can't stop thinking about how sexy his voice is.
After taking the pills he takes me back to the courtyard
"We are going to hang out with the damn nerd and half'n'half"
"Who..?"
He didn't answer me until we got there and I noticed the same green haired omega and a boy with a burned face
"Hey Kacchan."
"Hey bakugo, who's the girl?"
"I-I'm (y/n)"
"Kacchan, did you force her to come here?"
"NO I DIDN'T YOU DAMN NERD!"
"Shut up Bakugo" the burned alpha says as he grabs the omega
20 minutes later
"I-I just realized I don't know your names"
"I'm Izuku Midorya!"
"Shoto Todoroki"
"Katsuki Bakugo, just call me Katsuki"
We talk for a while and then we all walk to the dorms to hangout.
"Let's hangout at mine" Midorya said as we walked to his dorm, which they were all next to each-other
We all hear a ding and Katsuki looks at his phone and growls.
"What's wrong Katsuki?"
"Just some motherfucker"
"Oh okay..."
"Bakugo, who was it"
"FUCKING ROUND FACE"
"Ochaco?"
"Yes roundface"
I feel my heat coming back and I rush to the bathroom and frantically search for suppressants but I couldn't find any. All of a sudden a knock at the door.
"K-Katsuki" I could barely get out
(Sigh) he opens the door and takes me out of the dorm before I could even object
He took me to my dorm and sat me on my bed while he went and found the pills
He sat next to me and fed me the pills. I could tell it was taking all he had not to loose control. I tried to slow down my pheromones but they increased. He suddenly pushed my onto the bed with him on top of me.
"K-Katsuki w-what are you-"
He stoped me as he brought his lips to mine wasting no time to add his tongue. He brings himself up as he notices what he almost did and runs out.

The next day I see him in a hoodie with todoroki and midorya in front of a soba shop. I try to avoid them but I see the nine year old talking to black hair.  But as I run away from them I run straight into Katsuki
"S-sorry k-Katsuki...!"
He helps me up as he glares at me, most likely thinking about what had happened last night.

Katsuki POV
I stare at (y/n) remembering being on top of her.
"Fucking forget it"
"Again I'm really sorry"
She was so adorable I could almost die. She left and half'n'half looked at me with a fucking smirk on his face
"WHAT"
"I could be asking you the same thing- what happened~"
"STFU IT WAS NOTHING"
"You sure Kacchan~?"
They both looked at me expecting an answer, I caved in.
"J-just lost control of her pheromones"
I said as I walked off to who the fuck knows where as I see (y/n) again talking to the damn sleep deprived alpha. I growl as he looks at me and grabs her by the hips. As she- DOES NOTHING. I growl internally not wanted her to hear me.
(Y/N POV)
Shinsou grabs my hips and I can't do anything with his quirk enabled. I follow his gaze to a running Katsuki.
DID HE THINK IM DATING SHINSOU
When shinsou deactivated his quirk I push him against a wall
"WHAT THE HELL IS WRONG WITH YOU!"
"Whatever do you mean~?"
"Just stop shinsou, I don't like you, and I'm only here because you had to use your stupid brain washing quirk."
"Whatever" he got up and walked off
I run after where Katsuki  went but I couldn't find him.                                                                                         

I run to the dorms as I see his door open I go in to find an empty room but I hear something from the Bathroom as the door opens and I see a half naked Katsuki and we are both frozen and I release pheromones

"Y-your p-pheromones (Y/N)"

"K-Katsuki w-what are you doing..."

He pins me to a wall and holds my shoulders tightly

"K-Katsuki p-please-"

He kiss's me but its kind of nice and sweet. I melt into the kiss as his tongue enters and explores my mouth. My pheromones get less intense as he gets up and runs to the bathroom to get away from them
