Self-proclaimed "lover in the hearts of married women" AV director Takahashi Koichi, with a hidden agenda, let his wife's female friend stay in his home. A married woman who spent a night alone with herself has no reason to have nothing... Makoto is 38 years old this year, married for 8 years, with no partner, living in a dog-like apartment. The owner returns home after taking a bath and explains that he covered his forehead with a towel. The married women get to know each other at dinner, play in the tent set up by the director, and kiss. The married woman, aroused by caresses, looks at the erect shaft and repeatedly says "great", skillfully sucking on it. When it is inserted, she faints in pain, her voice hoarse and gasping. As she falls asleep, the director teases her, torturing her repeatedly with an electric massager. The next morning, she plays a prank on the sleeping director, and enjoys washing her body in the shower. When the penis penetrates her body, she moans and begins to breathe irregularly.
