Ex-girlfriend Elizabeth Darling, now his step-sister, sneaks into his room, her petite frame barely concealing her nakedness. She climbs onto his lap, her tiny pussy already wet and ready. He watches, mesmerized, as she grinds on him, her small breasts bouncing. She guides his hard cock inside her, gasping as she takes every inch. They fuck in missionary, her legs wrapped around him, their bodies slapping together, her tight pussy milking his cock until they both climax.
