In this all-adult mother-son role-play, a mother's devotion to her son is brutally exploited. Reiko visits a reform academy called Kikukai Academy, hoping it can straighten out her school-refusing son, who has become violent at home, but she quickly begins to question the headmaster's vicious methods. Then Hikaru, another mother facing the same problem, incurs his wrath and is dragged away. Reiko's feeling that something is deeply wrong with the academy proves correct, but by the time she understands the true meaning of its name, it is already too late. The two mothers have their asses penetrated by their adult sons and the instructors.
