The gym echoes with her moans as the trainer's thick cock pounds into her, her flexible body contorting to accommodate his size. Her tits bounce with each thrust, her nipples hard and aching. She wraps her legs around him, pulling him deeper, her pussy clenching around his shaft. He grunts, his fingers digging into her hips, leaving bruises. She cries out, her orgasm ripping through her, her pussy pulsing around his cock. He pulls out, his cock glistening with her juices, and comes on her ass, his hot seed dripping down her crack.
