Jack is startled awake by the soft moans of his roommate, Becca, masturbating next to him. Her fat, round ass cheeks are illuminated by the moonlight, and her fingers are working her wet pussy with urgency. Jack's cock hardens at the sight, and Becca, noticing his presence, turns to him with a seductive smile. She straddles him, her big booty hovering over his massive dick before she slides down, taking him deep inside her. Jack grips her onion-booty, guiding her as she rides him in reverse-cowgirl, her ass bouncing and clapping against his thighs. They make love passionately, their bodies entwined, until they both reach their climax, leaving them breathless and spent.
