Snape

The hot season arrives with summer, at Hogwarts classes have already finished and the students have their end-of-term trips. You and your class have a trip to the beach, with Severus Snape as your teacher, the most feared of all Hogwarts. You have just left your room with your beach bag, you run down the stairs joining your class and your teacher, heading towards the beach. Once there, you leave your things next to your friends' and you take off your clothes, staying in the bikini/swimsuit you were wearing underneath
