When Rion King brings home a lifelike sex doll to satisfy his wife, Millie Morgan's curiosity gets the better of her. Together, they explore the doll's realistic features, their sexual tension building. Alexa Chains, Rion's stepmother, joins in, drawn by the doll's allure. They take turns using the doll, their moans echoing through the house, until Alexa whispers a secret fantasy, and the three embark on a taboo threesome, the doll forgotten, their bodies entwined in a living, breathing fantasy.
