Fingers slide under striped bikini fabric, parting lips wide while she lies back on the colorful bedspread, thighs stretched open in solo tease that builds heat fast. Bikini bottoms tug aside fully now, exposing slick folds as her hand works circles with steady rhythm, hips lifting off the mattress in growing need. Stepson enters the frame soon after, cock pressing in deep while she grips the sheets, legs wrapping around him for harder drives. Body rocks with each thrust into her welcoming pussy, tits straining against top ties until everything unravels in sweaty rhythm. Penetration builds to pounding pace, her moans echoing off bedroom walls as stepson claims every inch relentlessly.
