This very popular mature woman, Natsukayama, is a tight-knit naked body!! Natsuko, who had separated from her husband and raised one son, Shiro, was unable to forget the violent sex of her ex-husband. And I often visited my ex-husband's house secretly by Shiro. One day, Shiro finds out that he is in close contact with his ex-husband. A foolish mother to a man...A brutality of handing over his father grew among Shiro, who did not see her lightly. And Shiro slowly tied this body with a rope in his hand.
