At a certain business hotel, a guest notices that the middle-aged room attendant is an alluring married woman. He calls her to the room for service, relaxes her with friendly conversation, and gradually introduces sexual topics. She blushes but seems surprisingly receptive, so he offers a generous tip and takes a chance by asking for intimate bedside service. Claiming that sex with her husband has become infrequent, she gives in and begins an intensely close, sensual service.
