Excuse yourself from the class and follow her
From Create Your Own Story
You follow Tina to the girl's locker room, and she leads you into one of the showers. She looks up at you shyly.
"I've always wondered what It'd be like to fuck you." She says, leaning into you. You feel immensely turned on and kiss her. She pushes you against the wall and begins to pull off your clothes. You let her, your hands wandering under her shirt.
