Just Another Workout Day

Saw my primary's new lover today. Knew they'd be meeting here; we had this talk beforehand. Saw them fuck in the parking lot, behind a truck. Couldn't help but watch as he rammed her from behind, balls deep, her tits bouncing like she was on an elliptical. Spent twenty minutes jerking off to it, pretending to wait for my own clients while they climaxed and cleaned up.
