A refracted family image, a shocking controversial work. A son who knows his mother's desires and gradually becomes uncontrollable. His parents divorced because of his father's cheating habit. His mother, Chiaki, raised her son single-handedly. Since she was an elementary school teacher, she was a serious, straight-laced and strict mother. One day, Chiaki's colleague Sanmoto begins to visit the house under the guise of work, and his son sees a thread of saliva stretching between their lips. To the aggressive Chiaki, the son involuntarily groped her crotch, and eventually her mother as a woman.
