Dressed as a sexy doll for Halloween, Alexis Pawg sneaks into Adam Muscle's room, eager to prank him. Unbeknownst to him, she's his stepsister, and he's none the wiser as she climbs onto his lap, grinding her curvy, big-booty figure against his growing erection. Believing her to be a doll, Adam indulges in her perfect ass, rubbing and squeezing, lost in his taboo fantasy. Alexis, aroused by his unknowing advances, plays along, whispering dirty nothings as he slips his uncut cock into her tight pussy, fucking her senseless while she moans in delight.
