A members-only sports gym in Tokyo. It's a gym that only hires beautiful female instructors and caters to the rich and famous. Yuuna, who is strikingly beautiful and has a well-toned body from her own training, arrives for an interview. After a practical interview using machines, she is forced to drink a protein shake that is still in development and faints. When she comes to, Yuuna finds herself kidnapped and raped by the owner and trainer. Continuous deepthroating leading to a massive ejaculation, machine restraint orgasm, hardcore 3P deepthroating—she is brutally trained with these sadistic throat exercises. Initially, she resists strongly, but gradually falls—her true nature as a woman who is meticulous about everything is that she wants to be messed up and used as an outlet for male desires. She was such a masochistic woman.
