A cosmetics salesman visits the home of a married woman named Rinono. The man wants to seduce Rinono at any cost, so he asks her to help with a survey and gives her tea laced with aphrodisiac samples. Due to the effects of the aphrodisiac, Rinono becomes overly sensitive and unable to resist as the man takes his chance to assault her. Her body is touched all over by a man other than her husband, and she is penetrated by his penis, feeling lewdly aroused.
