The echoes of grunts and clanking iron fill the gym as a muscular personal trainer takes a client through their paces. But as the session progresses, the trainer's professionalism wavers, her gaze repeatedly drawn to the client's growing erection. The client, a black beauty with big tits and a big ass, is equally distracted, her fingers creeping towards her pussy as she imagines the trainer's thick, tattooed form pounding into her. Unable to resist their growing desire, they lock the gym doors and give in to their carnal needs, the trainer's wet pussy squelching as she takes her client's big dick, their bodies glistening with sweat and satisfaction.
