Gym floor slick under dim lights, blonde femdom in shiny black latex pants and red bustier straps on her thick toy, circling the helpless male locked in red corset and crossed pose. She lubes up slow, then presses the tip against his tight hole, hands prying latex cheeks wide as he tenses in restraints. Towering over the treadmill with his legs bound helpless, she thrusts in steady, building rhythm while her heavy tits strain the corset fabric. Pegging deepens — he arches back against straps, latex creaking with every push-pull. She grips his hips harder, pounding faster until sweat beads on her pale skin and his body shakes uncontrolled. Strapon buried full, she owns the pace completely.
