Jon excused himself to the bathroom. The stone!, Jon thought. I can't believe it!
Jon had ended up as woman the last time he had used it. Since forgetting the stone, most of his masturbatory fantasies had revolved around transforming into a woman in some way. I guess now I know where that kink stemmed from...
But now he had the chance to transform for real! He thought back to his friends in the other room. He could even include them...
He just had to be smart about this. He could have as much fun as he wanted as long as he worded his wishes correctly. Something in his control that had rules and an end, but also something slightly outside his control, for fun...
A game! What game would Jon wish to create?
