Celebrating the first anniversary of Sayuri Hayama debut, we are releasing a new work based on the popular incest story "Kinjou Yuuwaku" by Haiji. The first live-action collaboration with "Mama Edition"! A mother, Mari, is found out by a man that she attempted to cheat on him, and he uses that as an excuse to force her into a relationship with her son, Minoru. Her son, who is right in front of her, doesn't realize that the woman is his mother, and he passionately devours Mari's voluptuous body... Though feeling guilty, Mari indulges in an affair with her beloved son. However, she doesn't know that it was her "son" who set this up...
