The only way for people to stop looking at Ariel X's abs is for a machine to pound her behind. If you look around her hard body, past her squirting pussy and her deep cock that goes in and out of her ass, you'll see Serena Blair in a painful squat above Ariel's face. This is the hardest way to train your mind. This is workout. Serena can't fail because of anything but that dark place deep in her will. Before she's allowed to, she has to push on the while machines fuck her, put up with Ariel's hard demands, and take the cumming. All of this is not easy, and Serena is playing a game with every part of her body. Serena is tired, but Ariel keeps giving her orgasm after orgasm.
