A woman is driven to a client, presumably to have sex for money.
Much of the story takes place outside of a strip club.
A man goes to a motel room. The neighbors are having sex (slapping noises) and the woman is moaning loudly. He looks outside later and sees a man and scantily dressed woman walking up, presumably she's a hooker.
A man and woman kiss. They are shown in bed, presumably post coitus. He gets out of bed, and his fully nude backside is shown.
