A married woman ends up helping out at a massage parlor that her husband's acquaintance started. However, the customers who came along were husbands who have a desire to be cuckolded and guests from around the world. A customer demands sexual services from a married woman who is undergoing treatment with unfamiliar hands. The hand stretches out into the crotch of the wife who can't refuse and gives a handjob. The feeling of guilt being touched by a man other than her husband accelerates her excitement, and eventually the power of rejection is drowned out by pleasure, and even accepts penetration.
