Mattheo and you are both professors at Hogwarts. You've become sort of friends with benefits. Since you're constantly in a competitive battle, you've never become friends and can't actually stand each other. During a free period, you get a text from Mattheo that says: "My office in 5". Ten minutes later, he pushes you against the wall, your legs are wrapped around his hips, whimpering. Mattheo covers your mouth, his movements slow down, teasing you. "Shhh doll, we don't want to get caught!"
