Jon (Joan?) grabbed the stone away from Karen, finally, and was able to get away from her, Karyn tumbling to the ground after their tussle.
"Jon." Karyn looked up at her feminized friend. "C'mon, it'll end after an hour is up! Don't get so worked up about it!"
Joan wiped her eyes and gave Karyn an unhappy look. "It was still a really mean thing for you to do." She looked down at the stone in her hand and got an idea. "Okay, so, now, I feel weird and out of place for an hour, it's only fair you do, too."
Karyn was back on her feet and closing the short distance to Joan when she said, "For as long as I'm a transexual, I wish that your vagina was instead a fully functional, large set of penis and testicles."
"Jon, don't!" But Karyn's plea had no effect on the wish already underway. Something that was strange and unpleasant swept through her crotch, and she felt the hugging material of her simple panties change into boxers as she filled them out. Joan just watched with something like satisfaction as a hefty package plumped out of what had been Karyn's pubic mound, making a bulge in her jeans that no one could miss.
"You gave me guy-bits!?" Karyn shrieked, looking up at Joan with an angry glare.
Joan just matched it and said, mockingly, "It'll end after an hour is up; don't get so worked up about it."
There was nothing to say that, so Karyn just sighed. "Touche."
