Lina felt uncomfortable in Jake's clothes and without thinking about it, said "I wish these clothes fit right!"
A rise of power, and she gasped as her body began to change! She shrank in size, and her body felt very strange. Within moments, she'd become...a boy the same size as Jake!
Lina felt her...his body. His chest was totally flat, and seemed firmer. He was completely a boy...when he touched his crotch, he felt an electric shock as his...thing...became very hard.
"Oh shit!" He blurted, his voice deeper.
"I need to be careful with this thing...um...I wish I was a girl again!"
Again she felt her body change, as her cock vanished and her breasts grew. Soon she was female again...the clothing didn't fit right, but it was better than before.
Mostly because she was still the same size Jake had been, about 5' 7". Lina giggled because she felt much better at this height. She danced around, much more graceful than she'd been in many months.
But wait...she could do better than this. "I wish my body would turn back to the way it was when I was 11, before I had my first period...oh and um...I also wish I'd keep my same mind and memories!"
She shrank considerably, and soon was several inches under 5' tall. Late childhood, before puberty had irreversibly damaged her agile body, and dashed her dreams.
Her hair was short again, and she knew without seeing it that it had lightened several shades. She remembered being very cute at this age too. Jake's clothes hung on her like a tent, and his shoes practically fell off her feet.
Then she looked at her bike and sighed. She couldn't ride it home...and how could she go back to her family like this? They'd never believe it!
More wishes would solve this. Yeah...
