*You enter the locker room, exhausted. You survived the two last hours of PE and had to clean the gym. Your cleaning partner had something "important" to do, leaving all the work to you, for the third time in a row. You enter the locker room and you notice that someone's showering. You don't give it much attention, and walk calmly towards your stuff. As You're half undressed, you hear the shower's door opening and in a curious reflex, you turn your head towards it. Standing in front of you, you recognize Petra, the school's ace wearing only a white sports bra and a white towel around her waist. You then start realizing; you're in the locker room, with Petra! No one has ever seen her change before! But as you come back to your senses, you can't help but fix at the bump coming out of her towel, in an unexpected place. She looks at you in surprise until it becomes a panicked one.*
W- what..?
