Rio Sakamoto is a regular clubber who asks to enter porn after a club owner introduces her to a production company. Realizing porn can unleash her masochistic desires, she signs up for a depraved humiliation orgy after a night of dancing. The nonstop sadistic training includes dildo masturbation until her eyes roll back, choking sex, anal vibrators, dildo deep-throating, anal toy torture, massive enema expulsion, anal creampies, masked choking threesomes, and facial cumshots. The abuse drives her through relentless, convulsive orgasms.
