Jon shouted at Zoe. "Quick, Zoe, get the rock Karyn's got."
Zoe saw Karyn, with a strange look in here eye, holding the rock. Zoe tried to grab it, but Karyn was too quick "I wish Zoe would stand still" she ordered, and then Zoe stopped where she was.
"I was going to let you off, Zoe dear, but you've crossed the line now. So what can I do with you?" Karyn eyed Zoe up and down. "Those clothes are wrong for a start. You say you're a goth? Okay then. I wish you were wearing a black leather peephole bra and panties with a zip down the front, thigh length black shiny boots, and fishnet tights."
The transformation was complete. "Please don't" pleaded Zoe, but Karyn looked at Zoe. "Oh no, I've only just started."
Jon realised with horror that Karyn was now completely power-hungry because of the rock. She could do anything!
"Right. I wish that you and Jon would swap heads." Suddenly, Jon's head was atop Zoe's body and Zoe's was on top of what was left of Jon's.
"Thank you for swapping my head with Zoe's" said Jon.
"You're welcome Jon. Right, Jon with Zoe's body, I wish you were unstuck, but if you tried to grab the rock you would be racked with the most excrutiating pain."
Jon felt himself go limp and collapsed to the floor. Slowly, he got up again, teetering on the high heels of the boots he was now wearing.
"Right, now for the final flourish. I wish that Zoe would get a hard on." Karyn watched as Zoe's new penis became fully erect. "I wish that Zoe's penis would only get flaccid again after Jon has either fucked her or sucked her off. I wish that Jon was in love with his sister, and wanted nothing more to make love to her or suck her off."
Jon walked over to Zoe and put her penis in his mouth, stroking it gently, getting quicker and quicker. After about ten minutes, Zoe came, and Jon felt Zoe's cum in his mouth. He was disgusted by the taste, but one look at his darling Zoe made it all worthwhile.
Jon moved forward and kissed his sister on the lips, the cum running out of Jon's mouth and down Zoe's cheek.
"Aah, don't you love a good romance?" sneeded Karyn. "Right, part two. I wish that Jon and Zoe..."
