Cody scrolled through the options- nationality, race, build, age- but he stopped scrolling when he noticed 'sex'. That seemed like a fun place to start, assuming this thing actually worked. He clicked it, and the drop-down box had three options: it was set to 'Male', but could be changed to 'Female' or 'Intersex', which seemed to have more options if you clicked it. For now, he just set it to 'Female'.
Once he clicked off, he realized the data on the box had changed. It now read:

Cody had barely had time to finish reading it before he began to feel very strange. His naked form on the screen seemed to be shifting, and when he pulled off his shirt to look at himself, he noticed he had goose bumps all over, and his skin felt sensitive. His nipples swelled up and he panted and gasped in an increasingly high-pitched girly tone as his chest slowly swelled, much of the rest of his body seeming to slim down as if his chest was sapping fat and muscle from him. Soon he had two soft B-cup breasts and a feminine body.
With the sensations shifting downward between his legs, Cody pulled off his pants and underwear, giving himself a perfect view of his castration. His balls moved up inside him and rapidly transformed into ovaries, his penis receded into a small sensitive nub, and his scrotum hunched up to his crotch and split open at its centre, forming a vaginal slit.
As the changes finished, everything slid into place in Chloe's head. She was not a boy, she was a girl, her new sex and body and name felt as natural to her as if she'd been one all her life. "This thing really works," she realized. She even had very similar feelings about her body as Cody had- she felt like her breasts and butt were too small.
Looking at the Chronivac settings, she wondered what to do next...
