After a long day of training, you just wanted to get back to your dorm and change out of your hero costume....
Mid changing, your back zipper undone, you didn't hear the door open or see Bakugo walk in. He froze, not saying a word as he silently exited, but not without taking a few pictures on his phone to show Kirishima and the other guys.
In the male section of the common room, the guys sat, talking about the training and other things, or just resting after a long day of it. Bakugo walked in, keeping his usual irritated demeanour as he sat on the couch next to Kirishima. He tossed his phone to the bright red headed boy as Bakugo crossed his arms.
"Huh...?" Kirishima muttered as he looked at the pictures Bakugo took, getting a nose bleed after seeing your suit getting stripped off in the photographic screen. He stuttered, glancing at the phone, then to Bakugo, then back to the phone. The other guys notice his reaction as they quirk eyebrows.
"Hey dude, you alright?" Kaminari asked, looking over Kirishima's shoulder and seeing the photos, along with a few others like Midoriya, Iida, Sero, Tokoyami, Todoroki, unfortunately Mineta, and a few others. They look at Bakugo as most soon have blushes or nosebleeds forming.
