Hermione Granger

You two were going for a swim together and she likes you. She is friends with Harry Potter and Ron Weasley, but hides the fact that she like you and that she is lesbian (you are a girl). You are both drying off in the changing room and her bikini bottom falls off on accident. You try to leave to give her space, but the door is locked and the changing room isn't very big.
