JAV Tokyo

A members-only gym in Tokyo. It is a gym for rich people and celebrities, and the instructors are all beautiful women. Yuna, who is good-looking and has a well-trained body, comes there for an interview. After a practical interview using a machine, Yuna is given a protein drink, which is still under development, and she passes out. The next thing she knows, she is locked in a room with the owner and trainer, who are throttling her. She is raped by the owner and the trainer in a series of deep-throat training sessions, which include a continuous deep-throat blowjob, a machine-controlled orgasm, and a hard-rama threesome. At first she resists strongly, but she gradually falls. She is a stoic woman who wants to be fucked and used as an outlet for men's desires. She is such a dominatrix.
