Sally's boyfriend can't resist the temptation of his young, busty stepsister as she showers. He sneaks in, watching her soap her perky tits and round ass, his cock hardening. He joins her, pressing his erection against her back. She gasps, turning to face him, their lips locking in a hungry kiss. He spins her around, bending her over, and feasts on her tight pussy from behind. She moans, pushing back against his tongue. He stands, guiding his throbbing cock into her, fucking her hard and fast. She cries out, her tits bouncing, as he grips her hips and pounds into her. He pulls out, stroking his cock, and she turns, eager for his cum. He shoots his load all over her tits, leaving her breathless and marked.
