Stay AWAY... (DekuKatsu Omegaverse)

Chapter 1

Katsuki P.O.V
Hey, I'm Katsuki Bakugo. I'm 14 and about to end my last day at this damn crappy middle school. The only thing that doesn't suck right now is the damned deku.
I don't know why but, every since a few days ago I've been feeling, well, it's this weird warmth that comes at the pit of my stomach. Also when-ever I'm near him I feel all hot and flustered. But, then again I want to be near him. Lately he's been, changing. Well, maybe he's starting puberty or some shit, but he's gotten taller and he's starting to bulk up. Well, today's pretty nerve wrecking. We get our assigned second genders today, and I really hope I'm an alpha and Deku is an Omega, so I can claim him. Wait, claim him?! What the hell am I thinking?!

Ugh, that dammed nerd. He's got me thinking about things I don't want to be thinking about. Anyways here goes. (Izuku meets Katsuki at the door to the school.) "Hey, Kachan!" Ugh, why does his voice have to be so attractive!? "What do you want nerd?!" I yell trying to cover my pink face.
He didn't seem to take my tone any different as he chuckled at me and then said, "Oh no! Come on Kachan, or we'll be late for the gender identification!" I checked my phone and realized it too, the thoughts being replaced by nervousness. "Oh shit! Well let's go!" I used my quirk, while deku ran with me by foot, he's still quirkless but, damn he's in shape. We got into the class just barely as the first names were called. Deku gave me a look that said, Good Luck! I just did my usual, "Tch" As I buried my face into my arms to act cool. Then Deku's name was called, "Izuku Midoriya, please report to the room next door." He nodded then, smiled at me sheepishly as he walked out the door. A few minutes passed and he came back into the room with his scent glands already starting to appear. I wonder what he got, but my thoughts were interrupted by the teacher calling, "Katsuki Bakugo! Please report to the room next door. I just got up and left the room. I went into the room next door and it looked like a mini doctors office. The man in there started to talk, "Are you Katsuki Bakugo?" "What's it look like?" He just rolled his eyes at me and told me to sit down. I sat down and he said, "Hold still, I'm going to pour this over were your scent glands will appear. Once the start to appear your scent will tell you what your gender is." "Tch." Was all I responded. I could only feel a cold, tingly sensation on my neck. He then used this thing on me that was kinda like those things you see scanning stuff when you buy groceries.
It beeped and he removed it,  Alrighty." He said. "Congrats! Your a male Omega!" "W-what?"
Was all I could get out. No, no, no. I-I can't be the weakest gender! He just handed me a slip of paper with a small black collar. "Alright so, now that you are an omega. You must wear this collar at all times, unless you are marked by an alpha. Also, when in heat you will experience some pain. But, unless you have an alpha to satisfy you stay in one protected place." I just nodded. As I walked back to the class, I noticed we were being dismissed. "Alrighty! Have a good summer!"
I heard the teacher say as I grabbed my shit and tried to walk out as quickly as possible. I didn't want to see anybody, especially not Deku. What would he think of me? I know I can't go home, my mom will beat me again if she finds out about my gender. I just decided to wonder around and found my self, in the back of the school. I completely forgot about my collar, until I was surrounded by an unfamiliar red haired dude.
I looked to see that he was, courting me!? I tried to get away, but my omega instinct made me submissive thanks to the alpha scent.
He pinned me to the ground, as he hissed. "Hello omega, I see you have no collar." "Get the hell off of me you fucking perv!!" I tried to use my quirk but he growled at me making me shut up. "Now, omega, is that any way to talk to an alpha." He started unbuckling my pants. I knew what was about to happen and tried to stop it, but it was inevitable. He shoved him self inside me, making me scream in pain. He kept thrusting and thrusting, the pain was almost unbearable. I tried to escape once more when he dug his claws into my arms making them bleed. Once he was through, he climaxed into me. I hoped he would leave when he said, "Now your coming with me cum rag." I wanted to cry for help but couldn't, as I was about to give up due, to exhaustion I heard a familiar voice, yell with anger. "GET THE HELL AWAY FROM HIM!!"
