Robert, intrigued by his girlfriend Sophia's birthday gift, a realistic doll, decides to explore its limits. The curious teen lubes up the doll's tight ass and begins to thrust, his cock hardening at the sight of the doll's lifelike moans. Sophia, catching him in the act, is initially shocked but quickly aroused. She watches, her pussy dripping, as Robert's pace increases, his balls slapping against the doll. With a final, deep thrust, Robert unleashes his load, filling the doll's ass with his creamy gift. Sophia, unable to resist, joins in, licking the doll's cum-filled hole, tasting Robert's pleasure.
