Jeff yawned as he sorted through the Chronivac options. It was getting late, but with Amy's help, he was just about done setting up his big changes. Hopefully because of his sleep-deprived mind, he won't wake up in the morning regretting his decision. But he wanted to make sure he took care of this while it was on his mind.
Amy seemed more awake than Jeff was. The apatosaurus-for-a-butt may have been content with the intial transformation she was dealt with, but she was excited for all the changes Jeff was about to make to himself, and by extention, herself.
With all the options in place, and a determination to make things right with Amy, Jeff hit the "Confirm" button and the Chronivac went to work.
Having stripped down to watch the changes, Jeff watched his hips, as Amy's thick blue skin started to travel around it. As it reached Jeff's crotch, his maleness started going away. Both he and Amy quietly grunted as his testicles were sucked into his body, being repurposed as a pair of ovaries. As his penis was sucked in, though, it did not open up into a vagina. Instead, his crotch completely smoothed over with the thick dinosaur skin, as the changes started spreading down his legs. And as the changes reached his feet, his feet and ankles thickened, his five human toes merging into three thick, clawed toes. However, the spread did not go much above his waist. Though apatosauruses were his favorite animal, he wasn't entirely willing to turn into one. Above his waist, he would wholly retain his humanity, while his lower half would become like an apatosuarus, giving him a look like a dinosaur-type satyr.
While his legs and feet were changing, Jeff was receiving some more feminine changes. His hips had widened just a little bit, and his body hair was thinning. He placed his hands on his chest, as his nipples puffed out a bit, and a pair of female breasts started filling out behind them. Not too big, likely around a C-cup. They were a bit sore and tender from the transformation, but that would pass, soon. Higher up, Jeff's shoulders narrowed a bit. And eve furthur up, what little facial hair he had disappeared completely, and his head of hair started growing out.
But what was really interesting was what was going on internally. The inside of Jeff's neck was changing, as his Adam's apple disappeared, and his male voice was changed to a female's voice. But that's not all that happened in Jeff's throat. He felt a light pinch, as a new, small hole opened at the base of his tongue. The texture of his mouth also changed slightly, as it gained an unusual taste. And his tongue felt slightly more sensitive. Like how Amy's mouth functioned as Jeff's anus, Jeff's mouth now doubled as a vagina.
The Chronivac pinged as his transformation completed. The next step was the reality change. For the most part, nothing in the immediate vicinity seemed different, as Jeff chose to be more or less the same guy, even as a girl. But he was so distracted by his changes, he failed to notice his discarded pants and underwear disappearing. In fact, he would later discover that he no longer owned anything to cover his lower half. With his anus being a dinosaur's head and his crotch smoothed out, decency was no longer a concern. And his dinosaur-like lower half was built to endure the elements. With no need to cover up, all relevant clothing of his had vanished.
Then came the final step. Jeff clutched his head as a headache came on, as the Chronivac began inserting new memories into his head. Amy had showed him the option, when Jeff expressed concern about blindly learning about his new female life. This way, he will already know everything he needed to about it. His old memories would not be replaced. Rather, he will be able to easily access his new memories as needed.
The Chronivac pinged one last time, having completed all its tasks.
The headache subsided a little.
Having felt the changes herself, Amy looked concerned. "Are you okay?"
Jess continued rubbing her head. "Yeah, that... was a lot to take in." Jess noticed something about her voice seemed different. But between the headache and the soreness of her transformation, she didn't have the energy to dwell on it.
"Your body does feel like it was put through the paces. Maybe we should sleep for the night."
"If I can with all this hurting." With a little tired awkwardness, Jess got into bed, covering herself and Amy under the blanket. Underneath the blanket, Amy curled herself into Jess's belly, and Jess pet Amy's head before quickly falling asleep. Amy soon followed.
