When I went to a men's grooming salon, I happened to meet a quiet, reserved female colleague with a large bust! Ever since I discovered she had a sexy part-time job, she became my paid massage girl; I can sleep with her anytime. Her name is Miyaji Rio. MIDA-450

By day, Rio is a diligent office lady working at a company. But in reality, she hides a secret identity as a "men's beauty salon hostess." One day, a colleague catches her in the act and forces her to perform sexually harassing massages. The man's desire for her voluptuous breasts, soft body, and submissive service gradually escalates. In the office, the beauty salon, the changing room, she's available for sex whenever called upon. Unbeknownst to her, Rio has become a J-cup breast-filled sex slave, a subscription-based rejuvenation massage hostess ready to be ejaculated upon at any time.
