A barbershop in downtown Tokyo. Yoshiko (Aoi), who lives there with her son Yasuo, was popular with men because she had a lewd body. What's worse is that Yoshiko is light-hearted and has a habit of following men when invited. However, I could not hate my husband who made such a mother, and not only that, I was raising a nasty feeling when my mother was in the store with customers and indulging in masturbation. And one day, Yasuo couldn't stand it and hugged Yoshiko tightly.
