Nishimiya Yume has just become an assistant homeroom teacher, her relationship is thriving, and life seems perfect. But the school custodian is a deranged pantyhose fanatic who constantly hunts for worn stockings. He fixates on Nishimiya’s 85-centimeter inseam and slender legs, soils the pantyhose soaked with her sweat, sexually assaults and abuses her, and records the ordeal for his twisted collection. His obsession and warped breeding fantasy keep escalating as she becomes the victim of his increasingly violent fetish.
