A man asks beautiful H-cup married coworker Maki Koizumi to be his massage practice model, and her kind nature makes her agree. What begins with her legs soon escalates to her ass and soft breasts. Claiming her butt is stiff, he brings out a wand and slides it from her cheeks to her pussy, making her climax; fingers inside make her cum again. Then they trade roles to massage each other's most pleasurable places. Finally he insists the inside needs treatment too, drives his bare cock deep into her vagina and finishes with a creampie.
