It was the day after his exam for U.A. and Katsuki was quite confident he was going to get in. He sat alone in Izuku's room on his lower bunk of their new bunk beds. Izuku was in the shower, humming quietly. Katsuki would never admit it but the thought of the other boy naked gave him warm tingles in his private area. He had known he was gay for a long time. He felt nothing towards girls though his fake friends at school talked about them all the time much to Katsuki's annoyance. They also talked about jacking off so frequently that Katsuki was disgusted and thought that something was really wrong with them. Then they bragged about having sex with girls. Katsuki shook his head at this. Who in their right mind would have sex during middle school? The risk of pregnancy and STD's ... it made Katsuki shudder.
Katsuki hissed in annoyance at the growing ache in his groin wishing it would go away. He decided to ignore it. He got up and went to his dresser and opened it. He looked at the clothes then selected a black sweatpants and a black baggy longsleave shirt as well as new boxers. The ash blonde checked to make shure the door was closed before stripping. He groaned slightly after pulling off his boxers feeling the cool air hit his throbbing erection. The grit his teeth and pulled on his clean boxers and the rest of his clean pajamas before dumping the dirty clothes in the laundry hamper. He crawled into bed after shutting the lights off. Izuku soon came into the room still humming and drying off his wet hair. Katsuki watched the green haired boy who was only in a towel as he forgot to bring clothes. Katsuki sucked in a breath as the dowel was dropped and he got a full view of Izuku's soft ass. Izuku turned slightly to the side as he put on his boxers unknowingly allowing Katsuki to see his most private area causing the ash blonde to blush darkly and his erection to throb harder. Izuku obliviously continued his actions of putting on his boxers then a white tank top and grey basketball shorts before climbing up onto his bed. Like clockwork Inko entered the room after knocking. She smiled softly and said in a soft voice "Good night boys." Both boys responded "Good night" to her. Inko continued to smile as she softly said "I love you both" before closing the door and waking away. After a few moments Katsuki heard the soft snores of his roommate and turned to the side pondering weather he should deal with his problem or not.
He decided against it and rolled to the side attempting to fall asleep with the annoying ache. Finally after a few hours it went away and the explosive teen fell asleep. Only to be plagued with nightmares.
