"A what?" Jeff exclaimed as his skin became a realistic looking rubber. It looked like normal skin, but definitely was now a synthetic material. All of Jeff's clothing disappeared as a copy of his mother's thigh highs materialized on his feet. Next his legs filled out the rest of the boots, becoming shaply and feminine, and giving him a bit more height. Next his ass pushed out into a perfect shape for grabbing and squeezing, as well as having enough movement to make his walking only capable of being described as seductive. His waist thinned out and became slender, as his back arched slightly. This was to support the new GG cup breasts that pushed off of his chest, identical in size to his Mother's pair. Each topped with a pink nipple.
His face became extremely feminine, and his mouth opened into a "O" shape, with his lips puffing up a bit. Then his hair grew, becomming long enough to reach down his back, ending finally at the back of his knees. His eyes also locked staring forward only, incapable of blinking too.
Lastly, his dick retracted into him, leaving behind a perfectly shaped pussy, with a full interior, which even included a womb. His asshole also became gaped as it too became one of his new fuck holes.
Now that Jeff has becone Jill, the sex doll, she stood up and turned to face her owners. "Good afternoon Master and Mistress, do you have any need for Jill today?" She found herself forced to say.
"Yes, please pleasure my while I make love to my hot wife Jill." Commanded her Master. Inside, Jeff was fully aware of what was happening to his, now her body, but couldn't stop herself from doing as instructed. As she dropped to her knees and unbuttoned her Master's pants, taking out his cock with one of her small delicate hands. Jill then began to give her Master a titty fuck, much to Jeff's horror and disgust. "Could this get any worse?" Jeff thought.
