Jon closed his eyes and felt the stone work its magic. When he reopened them, it looked like nothing had changed. He supposed he'd have to do some exploring before he could see the effects of his wish.
His train of thought was derailed however, by a knock on his door. He quickly went to hide the stone, only to find that he no longer had it. Thinking he'd have to search for it later, he ran across his room. When he opened it, he was surprised to find his mom standing in the hallway, in a tight green t-shirt he'd seen Karyn wear a hundred times and a pair of what also looked to be a resized pair of her jeans. Oddly enough, she now had long sandy-blonde hair and sported a huge pair of breasts. Remembering that these were the results of Karyn's last wish, Jon supposed (correctly) that his mother knew about the stone now.
"So Jon," she said, pulling the stone out of her pocket and giving him a playful smile. "You want to go hang out at the mall or what?"
