She was furious and upset that her best friend would do that to her.
"Jon give that stone here!" Without waiting for his answer Karyn snatched it out of his hand and started trying to take back the wish.
"I wish I was back to normal! I WISH I WAS BACK TO NORMAL!" Seeing that his friend was getting hysterical, Jon took the stone back and dodged her punch.
"Look, I get you're angry but you've got to calm down before you do something worse."
"Worse?! This, "Here she gestured to her package, "is all your fault! Change me back!" Enough was enough and Jon decided that it was time for her to learn some lessons about the wishing rock. It was mean but she had been the one to start all of the messes so far and had to be done to make things better in the long run.
"You know what Karyn? I wish that for today the wishing stone didn't hide your new changes and that everybody would be able to figure out what was in your pants. You need to learn a lesson Karyn, so it's only for today. I'll fix you later I promise!" Karyn wasn't having any of it and started crying.
"Jon how could you? I can't hide this." He shrugged and handed her a tissue.
"Guys have to hide erections all the time,I'm sure you'll get by. The bus might be bad though... I wish Karyn was in her homeroom seat." Jon still had a little while to get to school and started to think of ways to fix Karyn.
"Hmm interesting." He got dressed and noticed that he was circumsized. Probably becuase it was tradition in Karyn's family or something. Jon gasped when he realized how to get Karyn back to normal. After she forgave him, that is.
