The gym becomes a playground for John Strong and Ava Devine's taboo lust. John, Ava's step-son, can't resist his step-mother's luscious body, and Ava, bored with her marriage, finds John's young, throbbing cock irresistible. They start with a sloppy blowjob, Ava's makeup running down her face as she struggles to deepthroat John's massive cock. Then, John turns Ava around, spitting on her tight, little asshole before roughly pushing his big dick inside. Ava moans, feeling every inch of John's thick cock stretching her tight backdoor. John slams into her, making her wet pussy drip onto the gym floor. Their loud grunts and the sound of skin slapping against skin fill the gym as they fuck, oblivious to anyone who might catch them in their forbidden act.
