Jennifer reached into a pocket and fished out the stone. "Oh no you don't!" Karyn said sharply as she snatched it away.
"Karyn, give me that!" Jennifer huffed.
"No!" Karyn said. "You decided to try this, and we're playing by the rules. You're not getting out of this; you're spending a year this way just like the rest of us."
Jennifer's tail puffed, and Karyn knew that she was about to make a grab for the stone. Quickly, she whispered, "I wish that for the duration of the dice effects, Jennifer would also be ten years old."
Jennifer lunged, but Karyn held it up above her head, and to Jennifer's surprise she found that she couldn't reach it. She looked down at herself and realized what was happening. As her body shrank, her breasts disappeared and her curves straightened out, leaving her with the body of any other ten-year-old girl. "Dammit, Karyn!" she snapped, stomping her foot.
"I wish," said Karyn, still holding the stone aloft, "that for the duration for the dice effects, this stone would disappear into an otherwise-unoccupied dimension and return on top of the dresser in this room once the effects wear off." In the blink of an eye, the stone was gone.
Jennifer looked at herself. At least the breasts were gone, but she was still a girl, and she didn't like that at all. Her hair, which had come to just below her shoulderblades before, now hung to her waist; apparently it hadn't shortened when her body did. She was still wearing the shirt-and-skirt ensemble, but the clothing had shrunk to fit her new body.
"Why did you do that?" she groaned. "Now I'm stuck as a little girl for a year!"
"You were trying to weasel out of the game," Karyn said. "We were going to try this out to see what would happen if everybody was in the same boat. We are now, and I'm not going to let you just wish your way out of it."
Jennifer sighed. "Then why the little-girl thing?"
"Because you were about to pounce me and get the stone back before I could do that. This way, you were shorter, so I could hold it out of your reach, and if you did try to pounce, you wouldn't have enough weight to topple me. Plus, when you're ten, there's no real interest in the opposite sex, something I doubt you want to deal with in your present form, so I'm really doing you a favor. Now calm down, it's just a year."
Jennifer sighed.
"Oh come on," said Karyn, "what's so bad about being a girl?"
