The doctor's eyes gleam with lust as the mature brunette patient straddles him, her saggy tits bouncing with each movement. She grinds her pussy against his hard cock, moaning softly. He grabs her tits, squeezing them roughly, pinching her nipples until she cries out. She leans back, offering her tits to him, and he takes one in his mouth, biting down gently. She guides his cock to her pussy, impaling herself on it, riding him hard. He smacks her ass, leaving red handprints, as she fucks him faster, her orgasm building. She comes with a scream, her pussy convulsing around his cock. He pulls out, stroking his cock until he cums, painting her tits with his hot seed.
