Karyn blinked. She'd been afraid of what Sarah had in mind for her, but for a moment she didn't know what to think when she suddenly found herself able to move and feel like normal. She even had clothes on!
'What happened?'
Silence was her only answer, so she puzzled it through herself. She had been conscious when Sarah had made her wishes, so she knew what they had been, though unable to do anything about it. Now she used that knowledge to figure something out.
And what she came up with made sense. Karyn had not been confined to the form of a bra, as Jon had, thus when she'd been made to be inside Sarah's body, there was no telling what PART of Sarah's body that she would become. Apparently, the parts of Sarah's brain that controlled her motor skills and sensory input were parts of her body that would also fit inside her purse. "Neat, I'm in control of Sarah now."
Meanwhile Sarah was trying to scream, rather unsuccessfully. She was fully capable of seeing, hearing, and feeling everything that her body did, but for some reason she was no longer in control of any of it. It was still HER body, but so was Karyn now, so how, and why, did Sarah find herself unable to control her body? Shouldn't Karyn be subject to her will? But NO, Karyn was apparently in control of HER, now. Which sucked.
Karyn used Sarah's mouth to smile a little, and moved the appropriate parts of Sarah to look down at said girl's breasts, "Hey Jon, can you hear me?"
