Amateur beauty and married woman Tsubasa experiences her first visit to a female-oriented spa, nervously entering a hidden, intimate space with a handsome male therapist. Watch secretly as she indulges in 90 minutes of erotic pleasure during an oil massage that spreads warmth and sensation throughout her body. The session progresses from kissing to cunnilingus and handjob, climaxing with cowgirl-position cunnilingus that makes her lift her hips and convulse repeatedly in orgasm. Even this previously abstinent wife passionately begs for forbidden penetration. Mounting the handsome man's cock, she impales her long-dry pussy and rides frantically, lost in relentless ecstasy. Positions shift rapidly—from cowgirl to reverse cowgirl, doggy style, side-back, and missionary—as the hidden desires of a married woman explode in a raw, unfiltered sex documentary. A must-see record of uninhibited passion.
