The self-proclaimed 'lover of a married woman's heart' AV director, Takashi Koutarou, invites his wife's female friend to stay at his house with ill intentions. Nothing good happens when the married woman spends the night alone with him… Shoko, 28 years old, in her fourth year of marriage, no children, works at a resort hotel. Just as she is about to take a shower, the landlord, who shouldn't be home, returns. With no choice, the married woman ends up having dinner and staying the night with the landlord. When she finds out that the landlord is an AV director, she consults him about her marital troubles. She gets practical guidance on how to respond to her husband's advances… from body contact to kissing. The married woman inserts the erect penis just a little, moaning 'it's inside...' and reaches climax multiple times. When caught masturbating late at night, she is made to reach continuous orgasms with toy punishment. Upon waking up, she immediately has sex in the morning sunlight.
