Chapter 1- Hot shit

—————
"That will be all students! Have a good night and do not forget to finish those essays! It should be easy you're just writing about a dog!" Izuku sighs and watches his students rush out the room excited to go home. Izuku packs up his stuff ready to go home himself but then a knock at the door catches his attention

"Hm? Oh Kacchan what brings you here to UA?" Katsuki approaches Izuku and kisses him passionately with much lust "Ah~ Kacchan wait we're still at school" Katsuki ignores and kisses Izuku's neck making the Omega moan

"And? The students are outside it's fine~ now get ready for me to fuck you" Izuku nods and moans loudly. Izuku sits on top of his desk moving the paper work and things in his way. Katsuki rips the greenette's pants away having him bear from the waist down.

Katsuki takes his own pants off and pulls Izuku down onto his dick. "AH! Fuck Kacchan! Please more!" Katsuki thrusts hard in and out of Izuku's entrance making him a moaning mess with tears running down his freckled face.
"Fuck Izuku- damn you're tight today" Katsuki says breathlessly and groans as he looks at the pleasurful eyes of the Omega he knows well

Katsuki then lifts Izuku up having them make out lustfully. "Mngh- Ahh Kacchan!" Izuku moans and groans as Katsuki hits his sweet spot hard "Fuck! Deku god you feel so good" Katsuki moans and kisses the masterpiece of marks he placed on the Omega. Katsuki soon pulls away completely from Izuku. The two pant trying to gain their senses again.

"Fuck that was good" Izuku chuckles at Katsuki's comment and kisses him one last time "yeah it was" the two dress themselves and clean up. Katsuki was about to leave but he did one more peck "Oi tomorrow?" Izuku sighs and nods happily making Katsuki smirk.

Katsuki walks out the door as Izuku gathers his stuff. He soon goes home and slumps onto his couch and opens his computer to grade some work. "How did he get that answer? It's obviously C! 65% how can he do that badly on a simple test?" Izuku sighs and continues.
Izuku eventually fell asleep

............
The next day comes along and the lunch bell rings. "Enjoy your lunch break!" The students run out and soon came in Katsuki "Oi Izuku or should I say sensei~" Izuku looks over "Kacchan what are doing here? It's school hours!" Izuku lectures to Katsuki who yawns

"Well I'm on break and you are too! I'm horny let's go somewhere private we only got 30 minutes" Katsuki drags Izuku to a nearby storage closet and locks it turning the little light on. "Are we seriously gonna have sex in a storage closet?" The blonde nods and starts to kiss the greenette lustfully making Izuku moan loudly. "Shhh don't wanna get caught do you?"

Izuku shakes his head no "Then stay quiet" Katsuki says softly "I don't know if I can~" Izuku then proceeds to go down and unbutton the blonde's pants "Fuck Deku are you about-"

Katsuki immediately covers his mouth feeling Izuku start to suck him off. The greenette licks the tip of Katsuki teasing him which makes the blonde impatient "Damn nerd- fucking suck it" Katsuki pushes Izuku down on his dick making Izuku moan.

Suddenly a knock at the door caught their attention making Izuku immediately stand up and Katsuki zipping up his pants ".....Problem children" Aizawa frowns seeing Izuku wiping his mouth and Katsuki covering his very aroused friend. "Izuku get to your classroom their lunch is almost done and Katsuki go back to work" the two run out the closet in embarrassment. "After all these years I still have to deal with their bullshit" Aizawa sighs and goes to his sleeping bag

"Oi call me!" Katsuki yells out as Izuku nods and waves bye. Izuku soon enters his loud classroom but soon silence once they see Izuku

Izuku was still very embarrassed and tried to get back to what he was doing. "Alright guys let's start math!" The students groan and get their things out. As Izuku gets ready for math Kota notices a marks on Izuku's neck "Um Mr Midoriya what are those marks on your neck?" Izuku touches his neck confused and goes on his phone to see.
