We hit up couples on the street who seem to be in a slump in their relationship (sorry). We call only the boyfriend and persuade him by saying, "Would you like to teach your girlfriend the new joys of sex?" If she agrees, we invite her into the studio! We also have the girlfriend of another couple who was brought along do lesbian sex for the first time! The boyfriend is grinning as he watches the monitor in another room... but she gradually changes into a sexy one. Hmm, does she look better than usual? The boyfriend is flustered. "My girlfriend was seduced by another woman..." He is speechless! Impatient! Enraged! A complex web of human relationships! 6 couples appear!
