It took Kendra a little while to find the reality settings in the Chronivac - they were intuitively set under her profile. A realization that the placement probably meant it could have different settings for different people soothed her annoyance and spurred her to inspect each setting and read each informative tooltip fully. To her surprise and delight, the settings seemed incredibly exhaustive, but the ones she was interested were was at the top: "Are non-subjects aware of change having happened" and "Normalize".
She glanced down past her front legs to her rear legs and shrugged. It wasn't like the change was that permanent, not with this device that could alter her more. Kendra enabled both options and saved.
Kendra looked around the room. Nothing seemed different. Wait, that wasn't true... There was another dresser over by closet. That hadn't been there before!
She quickly got to her 4 feet and lazily walked over to the dresser. Pulling open the drawers revealed it was full of modified underwear for her rear legs and modified pants, skirts, sportswear and even a couple of dresses for her 4 legs.
"Huh. It's almost like I've always been this way." Kendra quietly mused to herself. It seemed plausible that if she went downstairs or outside or even to the mall, that people would likely accept her for the way she was.
She returned to the computer and did a quick search for her name. To her surprise a plethora of articles came up from around the time she was born. They all focused on a newborn who as an embryo had split into twins in the embryo, then the twins had partially re-merged but had not done so fully. The newborn, whom Kendra quickly identified as herself, as a result, had been born with a 2nd torso where the butt would be, and a 2nd pair of legs at the end of the torso.
"Oh that's neat. So it actually found a way to make me being a humantaur work without like... going to magic or something."
Kendra loaded up her facebook profile and was un-surprised to see that her pictures all showed her as a humantaur. It seemed her social life hadn't changed, although a few of the more goofy pictures had people sitting on her lower back. For some reason the idea of someone riding her edged on her nerves and the grimmace she had in a few of the pictures revealed that was not a new feeling.
All in all, it looked like her life had changed only a little, and if she wanted she could pack up the Chronivac and hide it away somewhere safe and enjoy it for a while. Or, she mused, she could experiment a little further. Or maybe involve someone else... Either with or without their knowledge....
