Aaron decided to start with something simple. After saving the personal details the Chronivac had recorded as the default so he could go back to how he was easily, he figured he'd just change his sex. As a nerdy sort of boy, he'd never had a girlfriend or even really been that close to many girls. So why not take the opportunity to find out how it felt to be a girl.
He copied the settings to a new file and clicked on Sex to change it from Male to Female. The name at the top of the list changed from AARON CARAGHER to ARIANA CARAGHER, and the other settings like height and weight adjusted themselves to fit a girl of his age and average build. Excitedly, he hit Apply.
He quickly began to feel funny. Looking in the full-bodied mirror next to his desk, he noticed that his face was becoming more feminine, the traces of facial hair vanishing and his cheeks softening. His hair lengthened and he could feel his skin softening and his body hair thinning, pulling off his jeans and realizing he suddenly had lithe, smooth, feminine legs. The male side of Aaron's mind was swimming in arousal, but the femininity was taking over, and he realized this when he noticed that despite how arousing he found the changes to his body, he was not hard. His soft cock almost seemed to have merged with his scrotum, and thoughts of taking something inside him were seeming more and more alluring.
Suddenly, he felt a pleasant itch in his chest, and pulled his T shirt off, standing naked in front of the mirror, watching his body change. A feminine figure was starting to form in his torso, and his skin seemed smoother. He noticed his nipples had begun to expand and swell, and pinched one. He panted as the newly minted mammary sent pleasure rippling through him, and his other hand quickly began massaging the other nipple. As Aaron eagerly watched his breasts grow, he felt his testicles move up inside him, starting to become ovaries, and his scrotum was reshaping, becoming flatter and longer and changing from a sac into a pair of lips, the penis at its top dutifully following its lead by beginning to shrink.
Almost simultaneously, the three most feminine parts of Ariana's new body finished forming. Her breasts finished swelling at a pert C cup, her penis receded into its hood and became her clitoris, and her vaginal opening emerged in her slit. She held herself up by her arms against the mirror and panted as she looked at herself, still reeling from the sensation of becoming a woman.
