She's troubled by her son, who loses his rationality and even sees his mother as a sexual object, but then she remembers her slutty mom friend, Mary Tachibana, and consults her about her son. A sex monster battle between Koichi, with his insatiable sexual appetite, and Mary, who offers to handle his sexual needs, now begins.
