Deku noticed that his childhood friend, Bakugo, was acting a bit differently around him. Why was that? Was it because he'd presented and the blond now knew he was an Omega? Or was it for a different reason entirely?

After he'd presented to the class, as everyone had, he'd been made fun of in a friendly way from his Alpha friends. Bakugo had gotten really mad at them and blew up a desk.

When Izuku asked why, the Alpha just scoffed and shrugged. "You're an Omega Deku. It was pure instinct that made me act. Don't go reading into it."

One day, Izuku had enough of it and, even though he was dangerously close to his heat, he stormed up to Katsuki's dorm and pounded on the door.

"What do you want nerd?" Katsuki demanded when he opened the door. He took a deep breath and held back a moan. "You're close to heat, so this is either really important or you're just stupid."

"It's important. I need to know why you've been acting different recently. You're more... Caring. It's kinda scary to be honest. You're an Alpha, but you haven't claimed anyone yet. Even Shoji claimed someone. So why haven't you? Kirishima isn't claimed, and you had a shot at Mina or Kaminari. Why didn't you take it?"

"Get in." He moved so the male could step into the room. He himself was on the brink of a rut, but he surpressed his Alpha to talk to Izuku, his childhood friend and crush.

Unable to resist an Alpha's command, Izuku did as told and sat on his bed. "Well?"

"I like you Deku, hell, even love you. I half expected you to accept Half n Half's offer to mark you, but you didn't. Why is that? You even rejected Shinsou and Floaty Bitch."

"Because I want you to mark me. I've known you since we were kids and I've liked you since then. Maybe not love like, but I've admired you since we met."

"Then let me mark you." Katsuki demanded. "Let me claim you as mine and we can be together forever." He offered.

"Yes, you may." He tilted his head, exposing his scent gland.

Bakugo took no time in marking him, pinning him to the bed. While lapping up the sweet taste of it, he undressed both of them. The Omega under him hit his heat and soaked his boxers with slick. The smell of him alone made Bakugo fall into a rut and there was no stopping him.

"Fuck Deku~ I'm in my rut~" He groaned. Izuku just moaned to encourage him. Katsuki undressed completely and used Midoriya's slick to lube himself, pushing in and waiting for him to adjust.

"Kacchan~" Izuku moaned, rolling his hips. "Y-You can move now~"

"I'm not starting slow." He warned. Izuku nods and let's the Alpha do what he wants. Katsuki started pounding him into the sheets, releasing his Alpha.

The smells the two released were intoxicating and it was lucky everyone on that floor was gone for the day or they'd possibly hit their heat or rut almost immediately.

After several long minutes of Bakugo absolutely destroying his Omega's hole, the green haired male moaned his name. "I'm gonna cum~ oh fuck please let me cum~!"

"Do it Deku~ Cum for me~" Bakugo purred. When he did, the blond pulled out, panting. "I didn't finish Deku~"

Taking the hint, Midoriya got on his knees and sucked on Bakugo's cock. It didn't take very long for him to cum and when he did, Izuku swallowed all of it, sticking his tongue out to prove it.

"Good boy Deku~" Katsuki purred and kissed his head. The two laid down and Bakugo covered them with his comforter.

"I love you Kacchan."

"Love you too Izuku."
