Considering there were now 2 girls in the house, neither of which old enough to worry about anything, Jeff decided that he would be the adult in the family. Pulling out the Chronivac, he noticed his mother's settings had been moved to the "templates" file, presumably to make a new one. The idea downed on him, and he sort of liked it: he would become his own mother!
After scanning himself, Jeff went to the templates and chose the "Karen" template to override his, but decided to save his own, just in case. Before becoming his mother, he decided to make a few changes to her body.
First off, he made it so the 'reality change' toggle wasn't on, so he would remember being Jeff, but clicked "Obtain Memories" so he could know how to do everything mom's do.
Second, he decided if he was going to take his Mom's body, he would change some of the things about her body to make the experience more enjoyable for him. Namely, her rather small breasts. Jeff increased the size of his mom's bust to a good 42DD, and increased the firmness and made it so he wouldn't need to wear a bra.
As a guy, Jeff had always wondered how it would be like to compare orgasms in the female body to those in the male one. His mother's libido was rather low, so he slided it almost all the way to the end, and pushed the slider for sensitivity all the way. He also made her asshole, clit, butt, nipples, and tits incredibly sensitive. Also, as long as he was using her form, he made it so she wouldn't be able to get pregnant.
After thinking for a moment, Jeff realized that the mother of 10 year old twins wouldn't be in her early forties. So, he scaled back his mom's age from 42 to 32, but she looked like she wasn't a day over 22.
After saving the changes, Jeff removed his clothes so he could witness the change. He pointed the emitter at himself and pressed the confirm key.
The changes were subtle at first, like his Adam's apple disappearing and the hair disappearing from his arms and legs, but they soon got more drastic.
First off, his hair went from a short brown crew cut, and grew slightly until it became a red shoulder-length style. His eyes were the next to change, turning from a murky brown to a brilliant ocean blue. His eyes changed shape, and his nose became slightly upturned and receded into his skull a bit more. His lips became fuller and more pouty, changing from a dull pink to a deep red, and blush appeared on his face, along with his mother's mascara and eyeliner. His jaw reshaped, and his ears shrunk, and soon they were decorated with tiny diamond earrings.
The changes began flowing to his body, and he felt his waist shrink and arms become less defined, his fingers becoming more dainty and the nails growing longer and turning scarlet. A golden wedding ring appeared on his ring finger, and a gold bracelet appeared on the opposite hand.
As Jeff looked down, he saw his aureoles getting bigger, to the size of a silver dollar, and his nipples began poking like inch-long bullets. Finally, bubbles of fat began to form underneath them and grew larger and larger. Jeff put his hands to his chest to feel the growth, and it felt weird. Finally, they stopped at a full 42 DD, fully natural of course. Jeff squeezed her breasts to make sure the Chronivac worked properly on them. Sure enough, they were firmer than his mother's breasts were before, and felt great to be squeezed.
The magic worked down to his crotch, and his dick was now hard but shrinking, becoming his mom's new clitoris. His nutsack shrank too and his balls retracted inside him to become her new ovaries. The scrotum rearranged itself into various labial folds and became his new pussy. Wanting to test out the sensitivity, she brushed past the clit and pussy, and she nearly had an orgasm with the pleasure.
Her legs became more defined and toned as her feet shrank and the nails were now the same colour as her fingernails. Jeff now went upstairs to his parent's bedroom to see the final part.
Looking at her butt in the mirror, she saw it expand in shape and lift upwards, becoming the dream of every female in Hollywood. She curiously stuck a finger in her asshole and shuddered at the pleasure. With her other hand, she began fingering her new pussy and rubbing her clit. Within seconds, her hand was soaked by her own juices. Jeff, now completely her mother physically, put her fingers in her mouth and savored the flavor of the pussy he was born from.
