Karyn turned to Jon, with a wicked smile on her face, and said "I just have to check if that wish is working.". She then walked in front of 'the Stud' and bend over to tie up her loose shoe lace. When Jon called to her, she looked around, while still bent over and gave 'the Stud' and nice view down her front.
Having set the ball rolling Jon and Karyn went over to the corner to watch as the changes started taking place, firstly his ass started to plump up nicely, apparently some fantasy elements were coming into effect as Karyn was observing complaining that her ass wasn't as wide or round as 'the Stud's new booty. His body thinned down with his legs softening and his feet shrinking to a more petite size, her arms were also thinner, and her hands more delicate and the fingernails painted a subtle shade or coral pink. Her hair filled out into a wild eighties style, with her face morphing between his favourite baywatch babes before settling into something completely new but very erotic with high cheekbones, and large pouting lips, her eyelashes were curving and batted with desire. Unfortunately the Stud seemed to focus most of his desire upon Karyn bust. He had developed into the most buxom girl in the whole of the school. She seemed very scared, having no idea what was happening, or why.
Jon then took pity on the new girl, and wished that her clothes had changed to reflect her new gender, and her name had changed to Joanne. With a green crackling flash, she was wearing a cheerleader's outfit, to perfection. It was at this point that a couple from the cheer squad came along and took the stunned Joanne off to training. The original wish still seemed to be in effect as Joanne's bust shrank to a more reasonable 38DD, although she seemed to be the only one who had noticed. Her nipples poked imprudently through her top as her thoughts wandered to the showers after training and the hot guys who would come to watch her train and shake her ass (but only as part of the training).
Karyn and Jon looked on a little dismayed, but hoping that 'the Stud' would keep her reputation for multiple partners with her new gender. Revenge would come one way or the other.
