It was Sarah that found the stone under the pillow. "So there really is a stone," he whispered.
Jon turned around and saw him holding it. "Is that it? Maybe we should test it out, see if it really works like Karyn said it did?"
"Hmm, ok," Sarah replied. His mind flashed back to Jon's perfectly shaped butt in his face, and said "I wish you were completely naked!"
The stone shined brightly for a moment, and when it cleared Jon was standing there in Bethany's amazing body without a stitch of clothing on!
"What did you do that for," Jon hissed at the lanky figure of the farm boy with a devious grin on his face. Suddenly, she became very worried... she hadn't thought the stone would really work, but it did, and Sarah had it. "Sarah, you're a girl too, you should realize how embarrassing this is," said Jon as she covered her crotch with one hand and threw her other arm across her large, perky breasts.
"Well, Joe-Bob here has always lusted after your body, and I signed up for this exchange to experience something new, so... I wish Jon were madly in love with me, and would have sex with me whenever I ask!" Sarah's smile broadened as the stone lit up, but Jon's face turned to a look of horror, but only for a moment. When the light cleared, Jon's expression changed to one of lust. The hand that was over her breasts began to pinch a nipple and knead a breast, while the hand that was over her pussy began to massage her clit. She wanted Sarah's new body so very badly!
