In a primal display of lust, a girlfriend submits to her lover's carnal desires, kneeling on all fours, ass high, and head low. He grabs her hips, positioning himself at her slick entrance, and drives in with a force that makes her gasp. Her body rocks with each powerful stroke, his balls slapping against her clit, sending waves of pleasure coursing through her. She claws at the sheets, her cries of ecstasy muffled by the pillow, as he fucks her mercilessly, claiming her completely.
