He had always had this fantasy of finding out what a vagina felt like and now with the Chronivac he had the opportunity to find out what his favourite models vagina felt like, it was like a dream come true. He realized that he was super turned on and rock hard at the thought of this change.
In the details of the proposed change he had designed he made it so that others were not aware that this change had occurred, the rest of the world wouldn't find it weird or anything. It would just be normal for everyone except for him, he pushed the initiate button on the Chronivac and Jeff realized he didn't want to miss watching the change so he dropped his pants and underwear and lifted off his shirt, standing naked in front of his full body mirror.
He looked down as he started feeling a strange warmth spread through his dick and balls, at first they started shrinking really slowly and he almost couldn't see it happening but he could definitely feel it. The shrinking started getting much faster and all Jeff could do was stand watch as his balls disappeared into his body all the while the sensation of warmth increased up into his hips and lower stomach. He guessed that his balls had become ovaries and he now had estrogen filling his body. just as he thought about this his penis disappeared but it kept going inside of him to form a neat slit, Jeff wanted to see more so he tried to open the slit slightly so he could see inside and as he touched it he was hit with shockwaves of a pleasurable new feeling. He moaned in pleasure just in time to see his new clit forming, he rubbed it gently and passed out backwards onto his bed from the new intense pleasure.
