"... make Karyn sturdier?.." I finished trailing off as I realized I changed dramatically.
As a teddy bear, I was an inanimate, plush, one-foot-tall toy - as far as I could possibly get from my original form of Jon Gibson not so long ago. But at least as a teddy bear, I had two legs, two arms and a head. Now, somehow even this vague feeling of familiarity was gone. I had no idea what Sarah turned me into and I wasn't sure if I wanted to face that reality.
My body felt completely foreign to her.
I couldn't feel any limbs and instead the entirety of my existence seemed to consist of... bloaty pudgyness... jutting forward from my back. Which in turn seemed to be stuck to some roughly flat surface. It felt like if my old human body got fatter and bloatier eventually absorbing my arms, legs and head, also splitting horizontally at some point along the way into two overgrown-human-sized fatty blobs.
I could feel the gravity pulling the mass of my structureless body down, pulling on where it attached to something at my back. What mostly seemed to hold me in one place though was my skin, which I just realized was only stretched in my front and then bending back and underneath her - but not at my back. I could also feel something like a vast piece of fabric clinging close to my volume up to about half-way my height. Where the bottom of my body lied, the fabric supported my mass, kind of like a hammock, sharing the load with my back.
A thought popped into my mind making me grateful for the fabric. Somehow I knew that if it wasn't there, my own skin would have to do the same job of containing my mass, probably stretching painfully.
My vision returned. It wasn't very good - everything seemed blurry as if I looked through a semi-transparent veil. I saw the bed she used to lay on as a teddy bear and the wall on its other side. Everything was even bigger than when I was a toy. I also seemed to be suspended some four feet off the floor.
Two more things struck me as unusual. Firstly, I felt... warm and... alive. A nice change from being an inanimate object. Secondly, I could hear a dull, rhythmical thumping noise right behind my left side.
As I took all of that in, the gears in my mind started spinning, presenting a terrifying conclusion of...
"So how do you like it as my boobs?" Sarah's voice came from the back and slightly above, was almost unbearably loud and strangely muffled. With each word I could feel the wall I was attached to move slightly and vibrate.
"Oh my god." I thought. "So I'm her..."
"I wish that when she is a part of my body, Jenny will use the name of that body part to describe herself and only respond to such name."
I would have sighed if they could. Even that last part of my humanity - a name - was stripped off me. Now all I was, at least until Sarah changed me again, was the fullest pair of tits on the cheerleading team.
"Hey breasts, what just happened?" I heard Karyn's voice in my mind. "Oh god, why did I just call you..."
"Yeah Karyn" I responded resigned. "It seems Sarah have just turned me into her breasts."
"Damn right I did." Sarah's voice was still overwhelming. "I wanted to keep you close but I wasn't going to take my teddy bear to school, was I? Besides, you little perv seem to enjoy the idea of large breasts without any thought of how much of a pain they can be. Let's see how you like your size after a long day of hanging off my chest. Especially after I wish that while you're my boobs I took every opportunity I had to flaunt you in front of cute guys. Maybe we'll even be lucky enough to have a quickie with David. Or Mark. Or Jonathan..."
