A curious stepmom, too curious for her own good, decides to swap places with her son's sex doll for a night. She climbs into his bed, mimicking the doll's pose, waiting for him to return. When he does, he's shocked but intrigued, exploring her body as if it's the doll's. She plays along, letting him have his fun, his hands and mouth roaming her curves. He fucks her missionary, then switches to cowgirl, her riding him with the same enthusiasm he'd give the doll. But this is no doll, and their shared secret threatens to blow their innocent family facade apart.
