It was now Jeff's Mom's turn to be surprised. She too was turning synthetic, just like her daughter Jill. In fact, she was becoming almost an exact replica of her, save for her hair which, while the same length as Jill's, was platinum blonde, not black. "Um, Honey?? Why am I becoming a sex doll too?"
"Because I wanted to be loved and served by sex doll servants who also were twins. So, you are not Jill's mother anymore, but instead, now you are her twin sister, Amy."
"But Master I... Master?" Said Amy as she finished her transformation into the sex doll twin of Jill. Jill looked at her sister somewhat sympathetically, eventhough this is more or less what Jeff was planning on doing anyways.
Their master took a seat on Emily, and ordered his new servants to pleasure him. Having received their orders, Jill and Amy began eagerly taking turns sucking their Master's cock while sitting on their knees. Jill however took the initiative and got up onto her Master's lap, face down, with her pussy pointing towards their Master's mouth. With her tits hanging down, encasing the cock, she used her mouth to cqp the tip of it, fully encasing the cock with her body. Amy laid down underneath them, and began rubbing her hands along thenunderside of her Master's long shaft with a few fingers. Her mouth was positioned just right to catch any overflow from her sister's mouth. She was determined to not let a single drop reach the floor.
Their love making continued for a quite a while, a few hours at least. After which, Jill and Amy both had their wombs filled to the maximum with their Master's cum. Something both of them secretly loved feeling. Even Jeff, who still was trapped inside and hated to admit it, but she also accepted that it really felt just that good to have so much cum inside of her body. She was starting to lose herself to Jill. Even now, Jeff already considered herself to be a girl. How long would it really take before Jill was all that remained?
Having finished serving their Master, Jill and Amy went to clean themselves up with a bath, however they just began making out with each other in the tub instead. Amy was actually the one who initiated it too. She knew Jill was infact her daughter, but also thought of her as a sister, as well as a shared romantic partner in their polyamorous sex life with Master. "So is me kissing you like this not considered wrong?" She asked Jill.
"Were twin sisters, and living sex dolls at that. So who cares even if we were to fuck each other?" Answered Jill, too turned on to answer how she felt internally. She slowly submerged her self and began sucking on Amy's breasts. To both of their shock, milk began to flow, and at quite a steady rate, out of her nipples. Curious, Amy returned the favor, and sure enough. Jill felt 2 streams of milk begin to flow out from her tits too. "Well, we are twin sister's I guess. So having matching milk fountains makes sense. I'll bet Master would love to be showered by our tits, right sis?" Commented Amy, with an unintended level of seduction in her voice.
Jill, not use to feeling milk flow out of her, only could shiver from the pleasure as she managed to answer quickly "Yes." Amy now moved to begin sucking her sister's nipple, letting her milk trickle down their bodys once her mouth cavity was full.
When their "bath" was finished. Both girls found matching maid uniforms, complete with the same boots as before, and a top specifically designed to support and display their breasts, fully uncovered. The skirt bairly covered anything too for that matter, and not a single pair of underwear could be found. What they did find though, were matching black chokers with an engraved dog tag hanging from a metal ring attached to them. The tags had their respective names engraved cleanly onto their front face, and "Property of Matthew Smith" on the back. For some reason, seeing the chokers had made Amy and Jill unexplainably happy. If either of them could, they likely would be crying tears of joy, but their synthetic faces were not capable of such things. However both girls felt the cool trickle of their lubricant which was being excreted by their auto-lubricating feature start to drip down their legs as it overflowed their pussy's and asshole's.
