“Have her ass grow every time she’s rude to someone.” Said Karyn
“Alright, I can do that.” Replied Jon as he started to walk over to her. He tried to speak as fast as possible to not get interrupted “Sarah, gain fat in your ass every time you’re rude to someone else. Have the amount you gain be dependent on how rude you are. As little as five pounds for something minor, and up to fifty fo something blatant. Don’t have anyone other than me or Karyn notice the growth until the next time you aren’t wearing pants including yourself. Forget everything I just said.”
Sarah just stared at him blankly. “What the fuck did you just say to me.” She was wearing loose fitting pants that got slightly tighter, but not yet form fitting. If Jon had to guess, she just gained about ten pounds.
“Oh, nothing.”
“What ever loser.” Jon could see her pants were now looking a little snug and she was trying to hide removing a wedgey, Jon would guess another twenty five as she walked away.
Jon walked back over to Karyn “What happened? Why isn’t anyone noticing that Sarah’s ass is over twice as big?”
“I made it so no one, even her, would notice until she wasn’t wearing pants except for us.”
“Why, I wanted her to be embarrassed in front of the whole school.”
“I do too, but I don’t want her to be sent home right away before any serious damage is done. Besides, what are the chances that she’ll be nice enough all day to not burst out of her pants by the end of school where everyone will finally notice.”
After giving it some thought “You got me there. This is better.”
“Yep, now lets get to first period. I don’t want to miss any of the rude antics Sarah will perform.”
