Mary Rock's tight body writhes under the sun, her bikini barely containing her lust. She plays with her pussy, fingers glistening, before hungrily swallowing a thick cock. Straddling him, she grinds, her ass slapping against his thighs. He flips her, pounding her pussy from behind, his balls slapping her clit. Mary's screams mingle with the river's rush as she cums, her pussy stuffed with hot cum.
