Softly, the stranger whispered into Jon's rock, "I wish this stone and only this stone would turn into a lacy C-cup bra that would only grant wishes while it is being worn by someone and only to the wearer."
There was a flash and the stranger was suddenly holding a pink bra, complete with bows and frills. They placed the unmistakably feminine object carefully down at Jon's bedside.
As they were about to leave, the stranger turned back with a second thought. Pulling their own stone from their pocket, the stranger added, "Furthermore, I wish that for each wish that bra grants, the wearer's breasts would immediately grow by a cup size and would remain that way for three days.
"Finally, I wish that the chest of any male affected in this way would become female in terms of both appearance and sensitivity for the duration. That should prove... amusing."
With that, the stranger left as silently as they had come.
