A muscular gym rat, his cock already stiff in his shorts, can't resist the temptation of his girlfriend's big ass and tight pussy. He bends her over, slapping her ass and running his hands over her curves before sliding his massive cock into her wet, welcoming cunt. He fucks her hard and fast, her moans echoing through the gym. She reaches back, spreading her ass cheeks, and he takes the hint, pulling out and sliding into her asshole. He fucks her in doggystyle, her ass jiggling with each thrust, until she squirts all over the gym floor. He keeps fucking her, his cock slamming into her ass, until he can't hold back any longer, pulling out to cum all over her big ass and back.
