Struggling with loan payments, a young couple asks the husband's father for help, but he refuses despite regularly visiting a men's massage parlor that offers happy endings. Tempted by the high pay, the wife secretly starts working there and learns handjob techniques from the hung manager. Her new skills nearly give her away when she pleasures her husband. Then his boss blackmails her into penetration, and once her father-in-law discovers the secret, she is made to use her soft, voluptuous body to service him too.
