A legitimate men’s spa in Tokyo reportedly offers post-workout massages. Yuu, a petite new therapist with a cute smile, wears skin-tight workout gear that reveals her nipples and a sweat stain outlining her crotch. Her body-to-body stretching and training feel almost deliberately seductive, sending testosterone soaring and leaving her client rock hard. He persistently pressures the easily persuaded therapist for an off-menu session until she agrees to raw sex.
