Cherry and Jack 

Jack has always wanted to watch his beautiful wife, Cherry, have sex with some other man so he is disappointed when he hears a rumor that she is having an affair with one of her co-workers. He follows the pair one night and learns the rumor is true. Annoyed at being left out and unable to watch them, he listens and becomes turned on by their joyful noises. At home later, he persuades Cherry to invite the man to join them and see what happens.
