This is the first work by Rin Higashi, who has completed her contract as an exclusive actress and is now a freelance actress. She was living a happy married life, hiding her past as a sex worker, but when she meets the former manager of the sex shop again, he threatens her and forces his dick into her mouth. Rin has to take customers in secret. Her perverted father-in-law finds out and threatens her, treating her like a sex slave. He re-educates Rin with two dicks, as she won't let him use her pussy. Rin remembers her instincts as she arches her back and reaches a convulsive climax.
