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 with another man... Misuzu, 30 years old, in her third year of marriage, no children, works at a department store information desk. She was supposed to borrow her friend's husband's room while he was away but ended up staying together unexpectedly. After drinking and loosening up, she consults with the AV director, who also makes how-to videos, about her lack of marital sex. After receiving advice, the married woman is made to change into sexy lingerie. Carried away by the lewd atmosphere, she surrenders her body, and as her vagina becomes wet enough to make embarrassing sounds, a penis is inserted, bringing her to orgasm. The married woman, who was supposed to have learned how to arouse her husband, masturbates with a toy in the quiet of the night and plays with the sleeping director's penis in the morning. During another round of sex, she enjoys the pleasure, saying, 'Does it feel good, Mr. Takahashi? I feel good too.'
