Jon watched as his feet slowly changed, his shoes becoming pink 3 inch heeled sandals, his nails were painted a matching pink, he could see the change move slowly up his legs as hair disappeared from then, as the change got higher his pants were vanishing from sight, and once the change got to his knees, instead of disappearing they became a frilly white skirt.
As the change approached his crotch Jon felt his boxers grow snug and then the change was gone, he could only assume he had panties on now.
The change continued up his body his T-shirt didn't take on a radical change but just shrank a bit and became much more form fitting around his thin waist.
The change got up to his chest and he could feel the breasts growing as his shirt tightened around them. as the changed passed his shoulders he felt the unique feeling of bra straps over his shoulders and behind his back.
It progressed over his face, Jon couldn't so much see the changes, other than watching his nose shrink, but he could feel them his whole face felt tingly. Finally as the top of his head tingled his brown hair fell in front of his face.
Jon stumbled to his feet, teetering on his high heels, noticing his hands also sported the same pink nails.
Jon was stunned, he would be stuck like this for 6 months as this 17ish year old girl. the only thing that made him feel better was that he was probably not the only person he knew that would be going through this.
Stuck, Jon figured he might as well go downstairs and tell his family what happened
