Kendra shifted her weight a little as she readjusted her sitting position. A little sadly she reached down and gently touched the smooth skin between her front legs. She was flexible enough that she could reach her genitalia between her rear legs, but needing to contort herself just to do that ignited a fire in her.
She alt-tabbed back to the news article from around the time of her birth, hoping it might have some insight into why her genitalia was all the way back between her rear legs, instead of between her front legs, like she would expect. Or for that matter, why she didn't have 2 pairs of genitalia... That made sense to her: If in this reality she was the result of twins merging during gestation, at least she could get a good deal out of it.
The Chronivac program's easy navigation quickly lead her to a section full of vaginas. Kendra was shocked by the number and variety of them, and quickly found the option to duplicate her own native sex. In the 3D preview she adjusted the duplicate sex to rest in her front crotch and was about to hit the "Apply" button when a thought struck her... It wasn't just her sex that she was missing a 2nd copy of.
She quickly searched for and added a duplicate pair of arms to her upper torso, below her existing arms. A pair of duplicate breasts came next and she spent several minutes getting them place just right below her existing pair. Before she moved on, she gave in to the nagging voice of self-doubt in the back of her head and tried inflating her breasts a little to see what she would look like. She had always liked sports and always been in good shape, but she also had not been blessed with very good genetics and her active lifestyle reduced her breasts even further.
Kendra quickly decided on a size slightly larger than a C-cup. If she read the information correct, they would be firm and perky enough to not sag too much, sizable enough to be proper handfuls, and not so big as to cause her problems when running or playing sports. Besides, there was a "Firmness Age Modifier" slider that had defaulted to -0.6. She slid it up to 0.1 and happily clicked yes to a confirmation that her breasts would actually become more firm and self supporting as she aged. Then, giddy with the freedom she now had, she also changed the "Post-Maturity Growth Age Modifier" from 0.1 to 1.5, ensuring that as she aged her breasts would grow quite noticably as time passed.
The 3D previewer looked appealing to Kendra - most of the changes were fixated on her upper body and she liked how they looked. But it felt like something was missing.
She quickly realized that while she had set out to give herself "everything she was missing a 2nd copy of", the preview still only had 1 head. Suddenly her enthusiasm waned and she became nervous. Would giving herself a 2nd head make a copy of her mind that she would have to share her body with? Or could it do something worse like create a sister from nothing? Would doing that make a person who also knew about the Chronivac? That could be a problem.
Kendra mulled it over and stalled for a few minutes before deciding to take a look at the options for the head, and if she didn't see something that made her comfortable, she'd just omit it.
