When the guy's friend came over with his new sex toy, a lifelike fuck doll, he was eager to give it a try. His friend had to step out, leaving the doll in his care. Being a fan of big tits, he found the doll's attributes quite appealing. As he undressed the doll, he noticed his stepdaughter walking in, and she was equally impressed by the doll's similarity to her. Seeing her huge tits, he had an irresistible urge to fuck her instead of the doll.He wasted no time, and before she could realize what was happening, he was thrusting into her. The sight of her big tits bouncing as he fucked her was too much for him to resist. After a wild session with her, he quickly dressed her up in the doll's clothes and waited for his friend. When his friend returned, he was thrilled to see his doll getting some action. Little did he know, it was his friend's stepdaughter all along.
