It was some time later. Karyn was splayed out on top of Jon, and Sarah was curled up kitty-style at his feet. All three were basking in the glow of their activities.
Karyn purred as she lay on top of Jon, her head on his shoulder, her hands touching his hands, palm-to-palm - or rather, palm-to-stone, as the stone was still stuck in his hand. "Oh, Master," she sighed happily. "You're so wonderful. So good to us. I just wish you didn't have to go to school or get a job. I almost...I wish you had a life like ours, forever and ever, and then we'd never have to be apart."
She sighed, wistfully, as Jon felt his body begin to change. He frantically tried to think of a wish to reverse Karyn's wish, but there didn't seem to be a way to reverse it without directly counteracting it. He felt his body change shape, his hips widening a bit and his waist narrowing a bit, his legs becoming long and shapely, his arms becoming slender and delicate. His entire body shrank, leaving him significantly shorter than Karyn. He yelped in surprise, only to find that his voice had changed to a soft soprano.
More changes were occurring now. His face became soft and feminine, and his hair grew much longer; if he hadn't been lying on his back, it would've reached to his waist, but as is it spread out in all directions, a crazed sea of hair surrounding his upper body on the bedsheets. At the same time, all his body hair disappeared, except for the hair in his pubic region. There was a swelling sensation in his chest, and flesh gathered under his nipples, expanding them out into two smallish female breasts, pressed against Karyn's as she lay on top of him, surprised but too enthralled by the changes to move. Then there was a sucking sensation in his genitals, and he felt his penis shrink back into his body, becoming a vagina, the back expanding into a uterus, his testicles pulling inside of him, becoming ovaries. Jon was all girl now.
Then the final wave of changes set in. Her ears relocated to the top of her head, becoming thin and triangular, covered in grey fur that matched her long brown hair nicely. Her fingernails and toenails became claws and her palms became padded as her whole forearm became covered in fur; her feet went even further, becoming full cats' paws, her shins also becoming fur-covered. Even Karyn and Sarah weren't this catlike. She let out a very female, very feline yowl as a tail grew from the base of her spine, and then it was over. Jon had become a petite brunette catgirl.
Karyn stared at her for some time, as Sarah, who had been not quite asleep when Karyn made her wish, was alerted to the goings-on by Jon's yowl. Both concubines gaped at the new Jon, who lay there, completely speechless. Then Karyn grinned happily and hugged Jon tight, smushing Jon's smaller breasts against her large ones. "I forgot about the stone!" she laughed. "We better be morecareful with it, huh?" Jon nodded, still speechless. "Well," Karyn purred, "I'll miss having you as my Master, but I'm so glad we'll never have to be apart!"
The hugging continued as Sarah joined in. "Welcome to the club, sister!" she smiled. "But I wonder who our Master is now?"
