As the couple's workout session heats up, so does their desire. The girlfriend, her massive tits straining against her tank top, can't resist the temptation of her boyfriend's growing erection. She pauses their workout, pushing him onto the mat, and climbs on top, grinding her ass against his crotch. She turns, her eyes locked onto his, and slowly unzips his shorts, pulling out his throbbing cock. She licks her lips, ready to give him a workout he won't forget, her big tits swaying as she bobs her head up and down, taking him deep into her throat.
