A boy and a girl are sitting next to each other
Boy: If you let me kiss you, I’ll give you a piece of chocolate.
Girl: Okay.
Boy: If you let me touch your boobs, you’ll get another piece of chocolate.
Girl: Okay!
Boy: If you let me touch your pussy, you’ll get another one.
Girl: You know what? At this rate, I’ll have diabetes by the time we finally fuck!
