Alyx Star, the nubile teen, is left to her own devices, her curiosity piqued by the arrival of a new sex robot. The doll, an uncanny replica of Alyx herself, stands waiting, its silicone form flawless and inviting. Alyx, feeling ignored by her partner Johnny Castle, decides to explore the doll's capabilities, running her hands over its petite frame, admiring its big, firm tits and tight, perfect ass. She can't help but compare her own body to the doll's, leading to a heated, self-exploratory session with her mechanical doppelgänger.
