Mai Sakashita, a female college student working as a private tutor, is sent to a household where she is subjected to relentless torment and abuse. Her ordeal begins immediately upon arrival, as she endures endless cruelty from her student, the student's parents, the family dog, and even a veterinarian. Her beautiful face contorts in constant agony. She is forced to defile food, perform deepthroat oral, endure coercive sex, clitoral clipping, mud and water torture, spanking, and treated like a female dog in brutal training sessions. She suffers group lesbian abuse and is left exposed outdoors. Harassed not only by men but also by women and even the pet dog, her body and mind are utterly destroyed.
