A married woman who decided to help a business trip massage shop started by her husband's acquaintance. However, the guests who came are cuckolded and have a desire to be a husband and guru's guests. A customer who requests sexual services from a married woman who is unfamiliar with the procedure. A hand extending to the crotch of a wife who can not refuse and handjob. The sense of immorality touched by a man other than her husband accelerates the excitement, and eventually the power to refuse is drowned out by pleasure and accepts even insertion.
