Dolled up (transformation)

"I'm not sure if that's a good idea, babe." John commented.

"I already signed the papers, they paid me 10k to test a new **** that could protect from diseases and significantly slow down body aging. You can't expect I'll pass on that!" His girlfriend, Jane, answered.

"But those kinds of tests are made in a lab, not at home. It sounds fishy!"

"I'll do! Every day!"

Despite her boyfriend reserves, Jane took the pill, and she just got a look of disappointment from him. It didn't give her any side effect or anything and didn't feel much different. She even thought that maybe she got the placebo.

Later, in front of the TV, John's hand passed on her leg and she felt in the mood to answer. Kissing him, her arousal grew fast. But Jane didn't know if it was just a good day or if it was some side effect. Both of them took off their clothes and got herself on his lap, rubbing her pussy against his hard cock. He could feel the warms coming from it as well as the moist on his erected member. Sitting on his cock, she moaned just by its insertion.

"Fuck, I'm so horny, baby." She mumbled.

He started to pump his cock in her wet slit, making her moan and cry out from pleasure. She indeed seemed quite motivated tonight.

That evening, she came three times in half an hour. That never happened. And she ended up exhausted.

It could have passed as some psychological reaction to the medication. But, every time she came back from the lab, she was clingy and horny. Her body was also looking more clean, with less and less imperfection on her skin. Her body hairs were being less and less visible, making her skin a bit shiny, while her eyelashes were growing longer.

"Do you... uh... I want to try... anal." She asked one day.

"Uh? You always found anal disgusting and dirty." John said, surprised.

"I know, but... I don't know... I feel more, confident... in a way... I want to do stuffs... sexy stuffs."

"Ok, sure! I won't complain."

Sitting on a chair, John grabbed her legs to pull her ass close to him. Then, slowly, but with a maintained pressure, he pushed his cock deeper and deeper in her ass.

"Ooooh... fuck... That's... That's even better!"

Indeed, it was tight and clearly different from her pussy, a bit more dry, but still, it felt great.

It wouldn't be the last time he fucked her back door, she was able to come as easily as vaginally, and it was a good change when they were getting bored of her pussy.

The more time passed, the more her skin looked perfect and shiny, her breasts big and round, and her pussy turning into a perfect plump slit. It made John feeling uneasy about her changes. But she loved it, taking pictures and dressing all sexy for him. She was also, almost constantly horny and less unsecure about her body, which was leading her to wear sexy clothes even outside, when the weather was fine.

Sex was of course amazing, she seemed to enjoy everything and didn't mind doing things John only seen in porn. The **** test was coming to a close, and it was clearly a success. She looked in great shape and sexy as hell.

Then, after her last day at the lab, Jane came back with permanent purple makeup and hair. Making her look even more like a sex doll.

"How do you find me? Like the change?"

"It's a bit strange, but, you look sexy."

"I know, right? They said the test was a success, I will look like this for a very long time, and my immune system is like nothing they've ever seen."

"That's great!"

"I know, right? I feel so sexy, and horny. I want to suck your cock so much right now."

"Sure, babe."

Jane went on her knees and immediately started to suck his dick.

While time passed, John started to get gray hair, while she still looked like a living sex doll. The only downside was that she was having losing her sense of self bit by bit, becoming more and more what she looks like... a sex doll.

"Babe, come here and suck my cock, please."

"Yes, daddy!"

Jane came out of the bedroom, where she was playing with herself, and started to suck his cock.

"Wanna watch a movie tonight?"

"Glurp... Yes, daddy... slurp..."
