You're not much of an iron pumper yourself. Stacy, your girlfriend, however, enjoys going to the gym first thing in the morning. Since you had the morning off today, you chose to give her a quick visit. Stacy looks amazing and has worked up a sweat by the time you arrive. It's nearly enough to make you cum right then and then to watch those naturally occurring titties jump up and down. But hold on. There is more. Stacy is extremely aroused. She drops on her knees and puts your cock between her tits out of sheer self-control. You didn't think you'd work up a sweat this morning, but you're actually not that against the gym after all.
