You Belong to Me

Izuku slid off the side of the bed and started pulling at the back of his shirt and pulled it over his head. He stood up and started unbuttoning his pants, pulling down the zipper.

"Ngh," He bit his bottom lip and moaned when he pulled down his pants, creating friction on his painfully hard cock. When Izuku had all his clothes off, he wrapped the blanket around him and walked over to the door with shaky legs. He set one hand on the door nob but it quickly slipped off and he had to catch himself on the doorway. His hands were matted with sweat and he had to wipe off both his hands on the blanket to get a firm grasp on the door knob.

Izuku opened the door slowly and peaked outside to see if anyone was there. When Izuku was sure that there was no one in the hall way he swung open the door and stumbled to the door opposite of Katsuki's room. He pushed open the door and slammed it shut behind him.

Katsuki flinched and turned around in the shower. He blushed like crazy when he saw Izuku and was about to turn off the shower. But stopped dead in his tracks when he saw Izuku smirk and drop the blanket. Exposing his naked body.

Katsuki had seen Izuku naked many times, but seeing him do things like these really made him blow a fuse. He locked the door behind him and licked his lips, slowly walking towards Katsuki and opening the door. He closed the door behind him before turning back to Katsuki and placing his hands on Katsuki's abs. Feeling them up and down until he had the feeling burned into his memory.

"Izuku, what are you doing?" Katsuki asked, trying to push him away. Izuku blinked up at Katsuki and leaned closer so that their noses were touching.

"I was getting hella horny. And my Daddy is the only one that can satisfy me~" Izuku whispered seductively. Katsuki hummed and smashed his lips against Izuku's. Burying his hands in Izuku's messy green mop of hair. Izuku pressed against Katsuki harder, desperate for more skin to skin contact. He placed his hands on both sides of Katsuki's head moaned when he pushed his tongue into Izuku's mouth. Their tongues twirling around each other, mixing their saliva together. Izuku moaned again making Katsuki's mouth vibrate and turned his neck to the side, deepening the kiss.

Katsuki pushed Izuku around so that he was standing directly under the shower head. Water plumbing him from above. "Let me guess, your heats bothering you?"

Izuku relied by bitting his lip and wagging tail. "Heh, I love it when you do that." Katsuki leaned forward and whispered in Izuku's ear. He reached behind him and grabbed the shower handle that controlled the temperature and turned it up to the point that it almost burnt Izuku. Katsuki looked at Izuku with a confused expression on his face when he whimpered. "Is that too hot for ya? I thought you'd like it. The simulation of the hot water raining down on us while we have sex. Sounds nice, don't it?"

Izuku tried his best to conceal anymore of his moans while Katsuki sweat talked him. The parents were down stairs, and if they were up here too long they would wonder were they were. They had to make this fast.

Izuku wrapped his arms around Katsuki's neck and jumped up. Katsuki quickly caught him and squeezed his ass. "Impatient much?" Katsuki teased.

"We don't have time. This needs to be fast." Izuku told the Alpha smirking. "Now fuck me like you mean it."

"You don't need to ask me twice." Katsuki muttered before slamming Izuku against the shower wall and spreading Izuku's ass cheeks and lining up his cock with Izuku's wet entrance. Izuku pushed Katsuki's head forward so that their foreheads were touching, enjoying the small intimate moment they had, and then absently realized that Katsuki wasn't wearing a condom.

"Wait- Ahh!" Izuku screeched. Before he could finish his sentence Katsuki slammed his cock in Izuku's entrance. Izuku bit down on Katsuki's shoulder to try and keep his moans sound but having Katsuki inside him didn't help.
