A 14. At this point, Jennifer was getting a little scared about her body's size and the high numbers she kept rolling. A fourteen was a guaranteed exotic change, and Jen knew she needed to prepare as she felt it coming her way. She took a deep breath, trying to keep her nerves as she began to feel the heat, this time in her lower half. She thought it would be her twin cocks, or her snatches, or the overly large rump behind her. But it was about to surprise her with something incredibly different.
Her ass suddenly shifted, causing her to stumble forward like someone had slapped her ass. Except, her ass moved backward, along with her twin cocks, her four balls and two pussies. Like someone was pulling her like taffy, her body stretched out, gaining an extra eight feet of length. While her torso extended, two protrusions appeared on the midway point of the torsos. They inched out quite fast, while Jen's back suddenly shifted into a 90-degree angle with the extension. The new appendages, two full feminine legs, touched down as her form was closing on its current shape. The sensations that ran through Jennifer's mind were of pain and bliss; she was starting to enjoy transforming, which really worried her. Having finished shifting, her eyes fluttered open to an unusual sight in her sister's mirror.
Before her eyes was the reflection of a 'humantaur' - a form of centaur spawned by the internet's love for human girls and weird bodies. Jen was familiar with them, as one such image had circulated Reddit several times. In the picture was a human-like woman with a second torso and legs, along with a horse tail and a custom suit of armour. The image was... alluring and spawned many questions about the logic of two pussies. She had that image in her mind right now, except she was staring at a real one. And while she had no front vaginas, she most definitely had two between her rear legs. Right behind two monstrous cocks. 'God, I'm becoming even more sexualized than a fucking morphed image,' she thought. Already her cocks were stirring, lengthening out to full mast as she kept thinking about her change. She tried to reach them but was surprised to only be able to grab their tips from above. Her change made it tough to manage them, and now she faced a dilemma. She needed to get off, but having no gripping room made it impossible to fully rub her cocks. Being 90 degrees from her lower torso complicated the matter. She needed to find a way to either fix herself or pleasure her body.
Looking around her sister's room, she found no sex toys, nothing to rub her dual penises on and no open holes anywhere. Jennifer stopped her thinking for a moment, 'damn, did I just think about fucking holes? Jeez, these poles are messing with my mind now.' After continuing her search, she yielded nothing. 'Shit, I might be out of-' Her thought was cut off as she heard someone bounding upstairs. She had no time to waste! Hiding would be her only option. Thankfully, Abby had a walk-in closet big enough to fit Jen's massive body. It was still a tight squeeze, but she managed. She knelt down on all fours with the door closed just as the intruder entered the room. It was...
