Washer's erotic wife

Harumi (Nishimoto) marries a certain laundry shop. Her husband, Yuzo, and her mother-in-law, Kiyoko, cherished Harumi, but Harumi had one thing that she was dissatisfied with. That is Yuzo's impotence. For Harumi, who was originally a playboy, this was extremely unbearable, so she indulged in masturbation to relieve herself... One day, Ishino, a playmate before marriage, comes to the store. Harumi goes to Ishino's house as he is invited. Around that time, Yuzo's mother advised him to buy an aphrodisiac made in South America.
