## Description
Kouhei works at preschool. He lives an extremely busy life surrounded by kids, but he is satisfied with his job there. He also enjoys watching their mothers looking forward to seeing their kids grow up. As he becomes close with the mothers, they tell him about their personal concerns. They are tiny complaints at first, but they gradually become something erotic such as, "about sexual relationship with husband" or "if Kouhei has a girlfriend?" His physical contact with them gets bolder day by day and Kouhei's libido gradually arises....

She is an extremely mild-mannered, and a somewhat natural-feeling wife. Her husband (50 years old) is a section chief at a trading company and is moderately wealthy.

She has only one man in her life, as they had an arranged marriage immediately after graduating from an all-girls' junior high, high school, and university.

Her husband, who is much older than her, sees her as his “daughter,” and she has had almost no sexual intercourse with him.

She is extremely frustrated, but is unaware of it. A minor incident leads her to recognize Kouhei as a “man,” and she is unable to stop her physical desires.
