For years, office lady Kumi has been forced to consume middle-aged men's semen as a sexual object. Through rigorous livestock-style masochist training, she has become so dependent that her fingers tremble and her body immobilizes unless she ingests semen at least once a day. This documentary captures the true nature of a genuine female masochist who transforms pain into pleasure. Part 5 includes strict training scenes such as being whipped with crotch ropes, being lent out at public toilets, toilet training, and controlled piss-drinking restrictions.
