The only way to stop staring at Ariel X’s abs is to have a machine pounding her ass. Follow your eye around her hard body, the deep cock plunging in and out of her ass, past her squirting pussy and you will find Serena Blair hovering in a painful squat above Ariel’s face.
This is ultimate form of mental discipline - this is exercise torment. That dark place deep in Serena’s will is all that can keep her from failing. She must push on the with machines fucking her, she must endure Ariel’s difficult demands and withstanding cumming before she’s allowed. All of this is not easy, all of this is a game with every inch of Serena’s body playing along.
Ariel squirts and rips orgasms after orgasm out of Serena’s tiring body.
