A throbbing 6-inch cock aches for satisfaction, and a silicone doll becomes the perfect stand-in for a forbidden love. As the man's fantasy unfolds, he pictures his stepsister's curves, her reactions, her secret desires. He pounds into the doll, his lust ignited, until he can't hold back any longer. With a guttural groan, he releases, leaving the doll filled with his hot, cum-filled fantasy.
