Vince Karter is touring Billie Star in the gym. He asks her out for drinks later but she has a better idea. She started sucking his cock right there in the empty gym. They're there when a busty trainer, Tina Fire, peeps at them from the other side of the gym, getting hot and horny as she watches. Tina decides to toy with the couple a bit before inviting them into the bathroom for a steamy and wild threesome.
