A hulking, muscular trainer is in for a treat when two new clients arrive at the gym, their toned bodies barely contained in tight, sweat-damp leggings and sports bras. The girls, with their big, round tits and fit, athletic frames, can't resist the trainer's charms. They engage in a sultry threesome, the trainer's thick cock sliding between their eager, dripping pussies as they take turns riding him on the gym floor.
