Karyn felt the stone warm in her hands as the wish was granted.
"Good, now with her out of the way I can get things done."
Karyn smiled uncharacteristically, looking down at her breasts, knowing they could not respond without her addressing them. A feeling of power ran through her. It felt amazing.
"You know, maybe it's good that nobody else knows about the stone."
Karyn reached up and squeezed one of her breasts, feeling it's weight as she bounced it up and down.
Jon's eyes would have gone wide if he had any. He felt a surge of fear flow through him as Karyn's voice shifted into a more cruel tone, and she refereed to herself as being the only one who knew about the stone.
He tried to speak, tried to warn Karyn that Sarah's body was influencing her, but it was too late, and he wasn't able to speak at all as a pair of breasts. He felt a hand cupping over half his body and lifted him up and down.
Karyn smiled again, moving her hand back away from her breast and peeking into her pants, spotting the panties which Sarah now inhabited. Karyn paused for a moment, taking a moment to lightly tease one of her nipples as she did so, knowing that Jon could feel every touch.
"I wish that these panties fit very snug against me, and that all the sensations of being my panties are twice as strong."
The stone warmed in Karyn's hand.
Sarah felt as her body tightened around her former legs, and she felt the taste and smell of her pussy and ass grow stronger. She felt as she wrapped tightly around her former pussy, and it's warmth grew stronger.
"I wish that my panties can never speak again, or make wishes using this stone. Finally, I wish that my panties will always crave the feeling of being wrapped around me."
The stone grew warm again.
Sarah couldn't help but feel herself relax at the words. The feeling of being wrapped so close to her pussy was comforting. The tastes, while not appealing, reminded her of home. This was where she belonged, everything was good with the world.
Karyn smiled as she looked down at herself. Sarah's body wasn't the best, but as she looked at it she realized it wasn't really worth the trouble to change around.
However, as she looked down she couldn't help but notice her breasts again, and the fact that inside them was her former friend. She knew that he would be hating his current condition, and something about that appealed to her.
"I think it's time I have some fun with these."
