Erin secretly replaced "cowslut" with "sexdoll". She was currently thinking under the influence of her new species being a bunch of super horny sluts, so her ability to think properly was slightly off. However luckily, the magic seemed to accommodate her somewhat for it. If going by literal wording, Erin had just erased Maddie from existance. But the magic instead understood what the horny cowslut was intending. Maddie was a "living" sexdoll, since only sentient beings could have the emotional capabilities to be shocked. She also made only herself and Maddie aware of the change.
Looking back at Maddie, Erin was able to watch the transformation happen. Maddie suddenly opened her mouth up wide. Her teeth quickly disintegrated into nothingness, and her gums became extra soft. Her cheeks puffed up a bit, shrinking the space inside her mouth, while not changing the exterior look. Her tongue and the roof of her mouth also inflated slightly, becomming soft and puffy. Her mouth cavity was now only a moist, squishy tube. It honestly was a bit gross to see.
But this was just the start afterall. Maddie's lips began to round out, forming a perfect O shape. It was impossible to distinguish what was once her upper or lower lip now. The circular gap in the middle tightened a bit, leaving a hole about the size of a quarter permanently open. Her lips then dawned a coating of bright pink lipstick.
Next to change was her eyes. They moved to stare directly forward, and her eyelids lowered slightly, giving her a more relaxed look. Her face became properly made up, without looking overly whorish, or like one of those cheep sexdolls. Instead she looked like a real makeup expert had done it. Apparently Maddie was to be a lifelike sexdoll.
Erin watched as the changes moved downwards, now focusing her breasts, which pushed up and a bit forward, while becoming fixed in place. Their natural position seemed to be one which made a good amount of cleavage, even without a bra. Her nipples became permanently erect, sticking out the full 4 inches. They looked just like how Erin's had looked like when she was being milked. Erin realized that Maddie was actually a "cowslut" version of a sexdoll. Finally her nipples lightened a bit, turning slightly light pink, similar to the shade of lipstick that she had on.
Moving even lower, Maddie lost all pubic hair. Her stomach thinned, and her pussy stretched open, creating a similarly shaped opening as her mouth. Her lips puffed up to somewhat cover the gaping hole. Erin imagined that any clothing she wore would now have a very pronounced, but also sexy camel toe. Although she doubted that any sexdoll would wear tight fitting clothes often. A similar change also happened to her asshole.
The last bit to change was her body lost all hair from below her head, and turned into a synthetic material, which felt similar to rubber, but definitely way more expensive. Maddie was now an extremely lifelike sexdoll. Nearly indistinguishable from a real person if you ignored her obvious fuck holes.
Now a complete sexdoll, the Maddie-doll just sat there motionless. "Erin... what just happened to me? I feel wierd, and I can bairly move my face. Even my arms and legs feel stiff." The sound came from within the Maddie-doll. Aparently the Maddie-doll now spoke from somewhere inside her body. The good news was that as Erin watched, the Maddie-doll began twitching subtlety.
"Oh, I am glad you can still move" comented Erin.
"Bairly, and wth happened to me. I can't see most of my body, but I can see that my boobs are all wierdly pushed forward even though I am naked. My nipples are super long and somehow very, very sensitive. Oh, but please Erin, don't touch them. Well, not yet at least. Same with my mouth, pussy, and asshole. For some reason, I think I will lose my mind if any of those get touched right now."
"Uh, sure. No problem. And you look super hot right now. It is like you are begging to be fucked." Erin was being vague with her response, while not exactly avoiding the real answer.
"Huh, well you are not exactly wrong. Now that you mention it, I feel like I could have sex for my entire life and never get tired or board of it. It is like I just feel empty in basically every fuckable hole in my body. But that can be for later. Erin, what happened, seriously please." Begged the Maddie-doll.
Erin grabbed her tail and began teasing the Maddie-doll's nipples with the tuft of hair on its tip. The Maddie-doll was helpless and could only cry out in pleasure as it begged her to both keep going and to stop repeatedly. However, because of her invoulentarry convulsions from the pleasure, the Maddie-doll quickly regained a lot of her lost movement back. Her face however remained the same though. She only could move her arms, legs, and bend her waist and neck. Basically below her head was able to regain back some normal movement capabilities. Although there was some, rigidity still, which didn't seem to go away entirely.
Erin was getting carried away a bit and had moved on to licking the Maddie-doll's pussy with her ass shacking playfully in the air. This of course only inticed Becca to shove her cock as far as she could into Erins own pussy. Erin of course welcomed the sudden intruder. Her tail, moving of its own accord once again, wrapped itself around Becca and locked her inside of Erin.
Not wanting to stop, Erin grabbed her phone and generated a new sentence. Holding up her phone, she showed the Maddie-doll what was made.
"The Maddie-doll is a one of a kind, hyper-realistic, sexdoll with a fully integrated personality, the ability to self pilot through almost any situation, has practically no maintenance, and if left alone, will solidify in the position it was left in until it is needed."
"I became a fucking sexdoll?!?" Cried out the Maddie-doll, still unable to move properly due to Erin constantly lapping up her lubrication directly out of her fuck hole (pussy).
