Jeff and Jenny built a rhythm. Despite it being their first time, Jeff seemed quite skill. Jenny was glad she added that to the reality change on the Chronovac. As her pleasure increased, her moans grew louder.
Soon her own changes started to set in. While Jeff pinched the nipple on one of her AA sized breasts, they suddenly swelled to an A cup. Her breasts continued to balloon outward, and Jeff switch to molesting the whole package. As they grew, he was able to adjust his hands movements to better massage them. Soon he was playing with a pair of double Ds.
Jeff seemed to like the improvements and quickened his pace. Jenny's voice hitched to a higher octave, but not because of the Jeff's change in technique. It was because of the other changes setting in.
Jenny's skin started to take a glossy shine as the changes advanced. Her moans becomes squeaks as her insides changed. Soon the sounds she made sounded less like a porno shoot and more like a dog's squeaky toy.
Her fingers fused into what looked like mittens, and her lips swelled. Her mouth was frozen into a comical O shape. Her hair transitioned into yarns, her red luxurious locks becoming a stiff mockery of their former beauty. Her eyes slowly grew larger and flattened as they became simple painted replications.
The only part of her left unchanged was her genitals, which was about to climax. As she reached orgasmed, Jenny let out one last squeak, which hissed and quieted as the last breath left the now fully inanimate sex doll. With the transformation finished, the doll was nothing but an inflated plastic toy.
It laid there, feeling content to have served its purpose.
***********************************************
Jeff pulled out of his toy. Realizing his thoughts, he found it strange that her could not think of the sex doll as anything else. He knew that it used to be his girlfriend, but he couldn't remember her name or face.
Jeff walked over to the Chronovac, he read the changes that had been put in. Whoever the doll was, it had made it so no one remembered who the doll was. In this new reality, Jeff's former girlfriend never existed, but he did receive this sex doll as a gift from a friend. It also seemed to give him the compulsion to think of it as his favorite toy.
Jeff wondered what he should do now.
