Jon is changed.....forever?

"Oops." Sarah said, moving slowly towards Jon. "I forgot to do something when I changed your clothes. And I should probably change myself back to normal first." Sarah thought for a minute, with Jon looking on.
"Hey," Said Jon. "If I tell you what to wish for, will you let me have the rock and go? Or at least let me leave?"
"Maybe." said Sarah, looking down at her improved body, now barely covered by a baggy sweatshirt she had thrown over it. "Tell me."
"Just wish that youcan change your bady anyway you like for a short period of time." Jon explained, fidgiting in the blue dress. "then you can make yourself normal again."
"That would work". Sarah said after mulling it over. She clenched the stone and wished that she could change her age to any age for one minute. One minute later, Sarah stood in the room at her original age, 16 and a half.
"You can let me go now." Jon said, looking at her.
"I said maybe..." Sarah said, looking at him as she carefully changed into a t-shirt and jeans under the sweatshirt. "I still think that you should be punished for playing peeping tom!" She finished and walked over to him.
"I didn't mean to peek! I just wanted my stone back!" Jon tried to explain himself. Glad that her parents were gone, Sarah simply told him that he should have knocked or given her an indication rather than watching her.
"Now," she said, holding the stone. "You will pay." She held the stone and mumble a few wishes under her breath. She walked over next to Jon.He looked down at her. "Of course!" She said. "I knew I forgot something!" Suddenly the dress grew tighter and the skirt slid up to mid-calve on Jon. "A girl usually isn't 5'11.5" unless shes tall and lanky."
"Now hold on here." Jon demandanded. "What are you doing? It's sick fantasizing about men in womens clothes, but putting them in them..." Sarah laughed.
"Just look at the mirror on the wall Jon." Jon did as he was told, having no choice in the matter. "Now Jon," Sarah stated. "we can't have you being taller than me now can we?" Jon's eyes opened wide as Sarah put her left hand on Jon's head and pushed down...and he shrunk! "Hmm. About there." Sarah said as she stopped pushing. Jon turned and found himself a little below eye level with Sarah, who was 5'7"!
"5'6.5"! Perfect!" Sarah grinned. "Now...how would you like your voice?"
"What do you mean?" Jon asked, already guessing. Sarah looked at him.
"your voice should be a hair higher then mine I think." Jon watched in horror as his adams apple shrunk and dissapered.
"wha.." he gasped, and then clamped his hand to his mouth. His voice was high, almost like Karyn's! Sarah smiled.
"Now for the rest of the changes..." She motioned and Jon looked at the mirror. First, his hair changed color, it's light brown changing into a brighter red, like Karyn's! It began to flow out, down and down, stopping just at mid-thigh. Then, his face began to change. It narrowed out, his checkbones becoming higher. His lips puffed up and swelled while his eyes changed from plain brown into emerald Green. Then waist of the dress quit being quite so tight as his waist narrowed out. Hair fell of his legs and arms as they became undeniably feminine and smooth.
"you'll like this!" sarah said, as Jon's chest suddenly narrowed into a young womens petite shoulders, the dress now resting lighly on them, with the exception of the large, loose hanging bosom. Jon looked on, terrified as the loose cloth suddenly filled with substantial breasts. Jon looked down just in time to see hid butt expand out to fill the last amounts of cloth. Now he was uncomfortable. Womens dresses were not designed for male organs, and the result of Jon seeing a beutiful young lady int he mirror, even if it was him, was taking its toll.
"We should change that!" Sarah said, looking disgusted at the crotch of the dress. She motioned with her hand. Suddenly, it was gone. Jon's ammoruouss feelings left. He was a women.
