Jodie Johnson, the busty, innocent-looking stepsister, finds herself alone with Lilibet Saunders, her rugged stepfather, on a steamy vacation. As they lounge by the pool, Jodie's itsy-bitsy bikini leaves little to the imagination. Lilibet, unable to resist her youthful allure, propositions her. Jodie, intrigued by the forbidden, agrees. He lifts her onto his lap, her wet, dripping pussy grinding against his growing bulge. He pulls her top off, exposing her luscious, full breasts. She moans softly as he pinches her nipples, his thick, throbbing cock pressing against her. She reaches down, stroking him through his swim trunks before pulling them off, revealing his massive, pulsating dick. She strokes it, feeling its weight, before sliding down onto it, her tight pussy stretching to accommodate his size.
