A high-end men's spa that requires a three-month wait for reservations. This exclusive establishment operates under strict confidentiality, with a strict no-sex policy and even touching prohibited—yet offers a one-of-a-kind service: full hidden-camera recording of authentic, uncensored sessions. Working here is Yamasaki (28 years old), a legendary men's spa mistress with a perfect figure—170cm tall, 90F bust, 61cm waist, 92cm hips. She specializes in big-tit oil massages pressed tightly against the client, orgasm denial techniques, slippery handjob sessions, and anal massage. Her "unlimited ejaculation" service is especially intense, delivering astonishing levels of pleasure. When she gets truly turned on, she thrusts her hips vigorously, transforming the session into passionate, full-on sex that feels anything but professional. An added secret option—bareback penetration—takes satisfaction to the peak. Though the next reservation is three months away, clients inevitably find themselves eager to return again and again.
