Forced by a strict and sadistic husband, Chiharu is a wife who continues to have a physical relationship with her son. A quiet and withdrawn son does not refuse to have a relationship with such a mother. At first, I was tormented by a sense of guilt, but as I came into contact with the young and majestic son's penis, I was confused. I was drowning in that body. When the husband notices the change in his wife's feelings, he abuses her even more sadly. And... finally the feast of incest of three parents and children begins.
