In a dimly lit room, Katie and Jay, dressed in robes, await their niece Kylie. As she enters, they pounce, pushing her onto the couch and locking the door. Katie, wearing only a strap-on, commands Kylie to strip. Kylie complies, revealing her young, firm body. Jay, naked and hard, approaches Kylie, who tentatively reaches out to touch his cock. Katie guides Kylie's hand, showing her how to stroke him. She then pushes Kylie's head down, making her take Jay's cock into her mouth. Meanwhile, Katie lubes up the strap-on, pushing it into Kylie's tight pussy, making her moan around Jay's cock. They continue their taboo threesome, fucking Kylie in every position, their moans and groans filling the room as they all chase their orgasms.
