Wish Misinterpretation

"I wish that Sarah would become male," Jon said. The stone flashed, then Jon and her sister Zoe watched the changes. In a matter of seconds, Sarah's body dissolved into what appeared to be ... paper? A large pile of envelopes mixed in with her clothes sat where Sarah used to be. Jon hesitantly moved towards the pile, wondering what had happened. When she saw that it wasn't just envelopes, but also magazines and postcards, she realized that her wish was misinterpreted. The wish had turned Sarah into *mail* instead of a male. On one of the magazine covers, there was a picture of Sarah. She was still transgender and naked, her cock extremely visible.
