In the dimly lit gym, the personal trainer's eyes linger on his wife's client, a petite Latina with an ass that won't quit. He can't resist, pushing her against the weight rack, his hands covering her mouth as he turns her around. She gasps as he slides his thick cock into her ass, her moans echoing in his palm. He fucks her hard, her big ass bouncing against his hips, her pussy dripping onto the gym mat. He grunts, pulling out, his hot cum coating her ass as she collapses, spent and satisfied.
