The grunts and slapping of flesh fill the empty gym as the blonde, her big tits swaying, rides her partner's cock, her pussy stretching around his thickness. She leans back, hands gripping his knees, as he pounds into her, her juices mixing with sweat, coating his shaft. As she cums, her pussy clenches, milking him, and he pulls out, his cock erupting, painting her stomach with ropes of cum.
