This is the first film from Higashi Rin, who has become a freelance actress after completing her contract as an exclusive actress. She was living a happy married life while hiding her past as a prostitute, but she reunites with her former brothel manager and is blackmailed, who forces his penis into her mouth. Rin is f** to take clients in secret. Her perverted stepfather finds out and blackmails her, treating her like a sex slave. Rin refuses to let him have sex with her pussy, so he re-educates her with two penises. Rin arches her back and convulses in ecstasy, remembering her instincts.
