Abrupt Speed Sex  I'm near a cash register in a small store. There is a man younger than me working there. A man named Tom who was in my Cellular/Molecular Biology class comes up to the register. A man is having sex with a woman. They are both on their stomachs. He is lying on top of her, and she is on the floor. He is thrusting hard and very fast. She is lying there moaning. He looks at his watch while he's having sex, and then gets up and leaves with his pants partially down. The woman sits up on all fours and stretches, rotating her pelvis. I'd like to have sex with her.
