"I wish I was your older brother," Mike said. One of the dollars of Wishing Money disappeared in a puff of smoke, and he braced himself for his transformation to begin. Only 98 dollars of Wishing Money remained.
Strangely, Mike did not feel himself changing at all. Just then, Jennifer gasped. "What's happening?" she said. Mike looked over at her and realized that was shrinking. She was getting shorter, causing the already oversized shirt she wore to increasingly cover more of her body. Although much of her body was out of sight now, it was plain to see that her massive breasts were deflating. Additionally, her face was gradually looking more innocent. Then, she shrieked as she passed through a growth spurt in reverse, feeling a sudden drop in height. At last, the remaining lumps of her breasts vanished, and the changes stopped.
"Aw, man," Mike whined as he walked up to her. "I didn't want you to get younger. I wanted to grow older."
Jennifer looked up at him fearfully after realizing that he was taller than her now. "What did you do to me?" she said. Her voiced sounded so high-pitched. "Why are you so big?"
"It looks like you're younger," Mike said. "...like maybe 10 years old."
"What!?" Jennifer squeaked. She held up her hands and stared wide-eyed at how small and soft they looked now. She rushed back to the bathroom to get good a look at herself in the mirror. The reflection of a very cute blonde girl in a giant shirt peered back at her from the mirror. She put her hands on her adorable round face. "Oh, this is just great," she said. "Now, I'm too young even for middle school."
Mike entered the bathroom and loomed over her with his comparatively larger body. "Well," he said. "At least, I get to be the older brother now."
She turned to him. "Mike, you jerk!" she said and gave him light a shove, which was all she could manage now at her size. "Don't do that again without asking," she said. "If you're going to use the Wishing Money, you need to know about the rules."
"What are you talking about? What rules?"
"The Wishing Money rules!" she said. "You're lucky that this wish only cost a dollar. Now, can I have the money back?"
