Follow me around the gym (voyeuristic style), starting off with stretching, when my shorts sag down, revealing my butt crack. Then a walk, leading to a jog, the stepper, and finally the rower. You make me jump, after having spied on me whilst I was doing my workout, when I thought the gym was empty. I can tell you're acting weird, eventually asking what you're hiding in your pocket. You confess it's your hard cock, you explain my ass crack has been on show through my whole workout. I'm embarrassed but that quickly leads to having some fun. You've seen my ass, now I want to see your cock. I'm very impressed and now want you to stroke it to my butt crack right here in the gym... better be quick before anyone turns up ;)
