Karyn got up early the next morning. After she had showered and cleaned up, she looked at her naked body in the mirror. She realized that her new power would make it easy for her to change some things about her body that she wasn't totally happy with.
Her breasts were back to normal size; while she didn't want the heavy DD jugs that the wishing stone had given her, she thought it wouldn't hurt to have a little more up top. She touched her breasts and grew them to a comfortable C-cup. She decided that her areolas were too big, and decided to see if she could shrink them separately from her breasts. To her delight, it worked. She made her nipples just a tiny bit bigger, and for the first time since puberty she was happy with her breasts.
Karyn proceeded to fine-tune the rest of her body. She made her hips a little wider, her stomach and butt a little smaller, her waist a little narrower, her fingers a little more delicate, and her ears a little smaller, too. She discovered she could shrink her body hair, and soon her armpits and bikini areas were effectively hairless.
She looked at herself again, and was pretty happy with what she saw. She still didn't like her straight, blonde hair, and started thinking about how she could fix it when her telephone rang. It was Jon.
"Karyn! The stone is missing!" Jon said, sounding panicked.
"Don't worry, Jon, I've put it somewhere safe," Karen reassured him.
"Thank God!" Jon sighed, "I need it to... fix... something."
"What could that be?" asked Karyn, feigning ignorance.
"My, umm... you know..." Jon began.
"No, I don't," teased Karyn, "what's wrong?"
Jon sounded embarrassed, even over the phone. "My penis is tiny... and my balls are still microscopic..."
"Oh, that," said Karyn, "I'm sure we can fix it later!"
"But Karyn, my first class is Phys Ed! And we're swimming today!"
"Okay, don't worry," Karyn said, "I'll figure something out."
Karyn got dressed quickly, thinking about how she could help Jon. She didn't relish the idea of touching Jon's penis and balls at school... what if they got caught? On the other hand, she knew that penis pride was a big thing for boys, and she didn't want to humiliate Jon in front of his entire P.E. class.
She realized that the wishing stone could probably help, but she didn't want to accidentally make a wish that she couldn't reverse. Her straight blonde hair was a constant reminder of how dangerous the stone could be.
