My gym rat wife, once a timid housewife, blossoms into a confident hotwife under the tutelage of our new, well-endowed trainer. Their workouts become increasingly intimate, with her ass bouncing on his face during squats and his hands wandering during lunges. I'm forced to watch, my cock hard in my pants, as she grinds on him during planks, her nipples visible through her sweat-soaked sports bra. The final straw comes when she bends over, her pussy glistening, and he slides his massive cock inside her, fucking her hard while I'm made to clean the equipment around them.
