Wishing Panties

"I wish that this stone and only this stone would turn into a pair of red silk panties that would only grant wishes to the person wearing them. In addition, the person wearing the wishing panties would enjoy wearing them and want to wear them as often as possible. Finally, if the person using the wishing panties would turn female from the waist down, if they aren't female already, and would stay that way until they gave the wishing panties to someone else." With that, the figure pocketed the second stone and slipped out again.
