Sweat glistens across big-assed trainer Rui Shinomiya as she lifts barbells with her tits bouncing, pressing herself close enough to make every client rock hard. Her strictly private one-on-one sessions turn into cock worship and screaming hard thrusts. During an oil massage, she lets a client knead her ass while she strokes his cock, then takes it on the workout bench. Her whole body shakes, her hair flies, and she cums again and again. Somehow this gym attracts nothing but huge cocks, and the air is always thick with sex.
