As she was still quietly perusing through the options offered her by the Chronivac, a strange thought entered Kendra's mind: "Centaurs and other such beings have tails, so why couldn't a humantaur?" She had to be careful, though: as far as she knew, there was no going back once the changes were made to her body.
Turning her attention to her hair, she found a hair tie and tied her hair back in a ponytail, the tip of which hung less than an inch above her lower torso. Gripped by a sudden flash of inspiration, she entered "I have a tail like a horse." As soon as she entered the change, she once again found herself completely naked from the waist down, standing upright and firmly rooted in place - this time with her rear legs and butt facing the desktop, her vagina on full display.

But it wasn't enough - a strange passion and desire still burned within her, and she needed more!
She had yet another strange thought enter her mind: "I'm already a freak...so why not go all the way?"
She once again sat in front of her computer, this time with her rear legs in a kneeling position on the carpet while she used her lower torso and front legs as a tripod. She then entered "I have..."
