Robbin Banx, the thick-assed MILF, takes a skinny dude under her wing for a personal training session in the gym. Her big, round booty is encased in tight gym pants, begging to be touched as she guides him through exercises. She can't help but grind her ass against him during lunges, feeling his growing erection. The gym's empty, but the risk of being caught only heightens their arousal. Banx's milky skin glistens with sweat as she leads him to the yoga mats, straddling him in downward dog, her pussy rubbing against his hard cock through their thin workout clothes.
