A little game of mix and match

You could probably fuck your father into eager submission the same way you did Zoe but you're not keen on the idea of screwing a guy even in this dollified state.

Luckily, your previous experiment with your sister suggests a solution.

Carefully you tease apart the almost invisible seam around dad's neck locating the fastening pins and popping them free. His head lifts off easily and you set it aside while you repeat the process on your mommy-doll. As you'd hoped parts are fully interchangeable between the two dolls and your parents heads lock neatly into place on each other's bodies as if they'd been made that way.

Next you detach your dad's dildo cock and balls and swap them for your sister's pussy.

Lastly you reconnect Zoe's limbs and revert her to her Zoebot state.

"Zoebot online" she says impassively seemingly indifferent to the plastic phallus that now juts from her crotch "awaiting instructions from master."

You grin admiring you're handy work. Your cuntboy father-doll with your mothers head. Your mother's milf sex doll body with your father's head attached and your teenage futa-bot sister ready to comply with you most perverted whim.

The only question is which of your new toys do you want to play with first?
