Self-proclaimed 'lover of a married woman's heart' AV director Takahashi Koichi invites his wife's female friend to stay at his house with ill intentions. Nothing good happens when a married woman spends the night alone... Yuriko, 36 years old, in her 12th year of marriage, no children, receptionist at an English conversation school. The married woman relaxing alone at Takahashi's residence is changing clothes when Director Takahashi returns home. Surprised and confused by the sudden event, the married woman eventually enjoys a lively conversation with him over drinks after they dine out together. Shocked to learn that her friend's husband is an AV director, the married woman confesses that she is bisexual. The married woman, who is sexless with her husband, learns how to be seduced by men from the director. In the flow of things, they kiss, and the married woman, who accepts the director, is played with sensitive spots and becomes ecstatic. Happily sucking on a erect penis for the first time other than her husband's, she begs, 'I want you inside me.' The married woman moans intensely as it hits deep inside. Before bed, she is made to climax with a toy, and the next morning, she aggressively takes control of the director, moaning loudly with another man's penis.
