Fucking your inanimate milf dad with Zoe's help

Obeying your orders without comment or complaint Zoebot lifts your mother's artificial body with your father's head attached onto the bed. She handles the bulky doll easily suggesting a level of strength that makes you glad she's completely under your control.

You have her lay underneath him while you climb up behind him taking a firm grip on his plump doll's ass to press your cock into the crack.

"How does it feel in there Daddy?" You ask reaching around to grope his soft fake tits "I bet you love it. These big milf tits. This hot woman's ass. Your daughter's tight little cunt between your legs, so hot and needy it's driving you crazy."

Zoebot shifts underneath them as she positions the tip of her dildo-cock against his pussy while you push the tip of your cock against his tight back passage.

"Oh yeah take it you little bitch." You groan as you and Zoebot thrust together plunging deep into him "That's right your nothing but my bitch. Getting double teamed by your own children and loving every second of it."

Zoebot fucks his borrowed pussy with a relentless mechanical pumping while you ride his ass like you're breaking a wild bronco. A real woman would be screaming under the rough pounding you're inflicting but the doll's artificial ass takes everything you can give it and more besides.

"Master," Zoebot's voice cuts in something close to urgency in her flat mechanical tone "This unit is experiencing unexpected stimulus. This unit believes it may be approaching climax!"

"Yes!" You cry on the edge of your own orgasm "Cum with me. Cum in our helpless doll and we'll make him our subby little bitch together."

With a deep groan you empty your load into the doll's ass at the same time your robot sister stiffens and shudders through her own release.

You roll off flopping on the bed besides them. You're short on breath and your cock is raw and aching from over use but thoughts of what else you could do with with the fantastical raygun throng in your mind...
