Tiffany's personal trainer rides her so hard, she finishes every workout with her clothes soaked through and sweat dripping between her perky breasts. During their session, Tiffany noticed Nat feasting his eyes on her body, and made a show of dropping her ass to the floor in deep squats. And when Nat put his hands on her ass to give her glutes a squeeze, Tiffany was happy to let him feel her muscles flexing with every pump. Finally, Nat went for it and pulled her in close for a deep kiss, opening the door for Tiffany to get on her knees and suck his cock. Watch how much fun they had working up a sweat in today's hot gym sex scene!
