When they got to Jon's house, they went to Jon's room and got the stone. Jon gave it to Karyn. "OK, it's your turn to try the stone. What do you want to transform?"
Karyn held the stone. "I wish I had the same sort of powers as Jon only I want to be able to turn myself into a magical shemale witch with the power to transform and control people and put spells on them. Like Jon, I want to be able to return myself to normal, and the people I've transformed if I want to."
Again nothing seemed to happen. Karyn put the stone back in the box and willed herself to change into her new shemale form. There was a brief whirlwind and Karyn was a naked Shemale witch. She now had the powers to change back and forth just as she had asked the stone to grant her.
"Whoa!" exclaimed Jon. "You wanted the same powers as me! I thought you would be disgusted with me. After all I did do some pretty awful things with my new powers."
"Actually", replied Karyn, "I think it was a very clever wish. You made it so it's not permanent and now you have special powers. That's better than wishing for a change you can't undo later. Besides I have a plan for my new powers and I want you to help me."
"What are we going to do?" Jon asked.
"We are going to go back to the park", Karyn answered, "Now bring your digital camera. I want you to take photographs as I transform Craig Thomas"
Jon took in a breath. Craig had asked Karyn to a school dance then turned up with his ex-girlfriend. She had never forgotten the humiliation of going home by herself minutes after she had arrived in her best ball gown. She had learned later it had all been a setup. They hadn't really even broken up. It was just a trick to make her look stupid.
Craig took a jog in the park at about this time every day. Karyn and Jon hid in some bushes near the running track. Jon had the camera. Karyn turned into her naked shemale form. She stood with some bushes hiding her cock, so when Craig jogged past all he could see was her top half, bushes hiding the rest.
"Oh Craig", Karyn called, "I've got something for you. Don't you want it?"
Craig saw Karyn's naked breasts and walked quickly over to her. Karyn took his hands and placed them on her breasts, "I want you", she said.
Craig stroked Karyn's breasts and kissed her. He hadn't yet noticed she had a cock. "I want you", Karyn moaned as Craig kissed her, "I want you Craig, I want you to..SUCK MY COCK!"
Craig looked down and saw Karyn's shemale cock. It shone with the same hypnotic light Jon's penis has used earlier to hypnotize people he had transformed. Craig couldn't look away, the cock drew him in. Craig put Karyn's cock in his mouth and began to suck.
As a shemale witch, Karyn could just cum and cum and cum. Her cum was also magical. As Craig drank it, he found himself unable to stop sucking Karyn's cock. It was magically taking him over. He tried to stop himself, but he couldn't. His hands fell away from Karyn's breasts as the magic took him over. Craig's clothes disappeared as the magic began.
"That's it you loser. Suck my cock for all you're worth." Craig had always made fun of any girl who had sucked his cock often calling them his 'cocksuckers' as a schoolyard taunt. Once they had done it, he never let them live it down. Unfortunately he was the sort of boy who could always get another girl to do it no matter how obvious it was he was just using them. The way he had humiliated Karyn at the school dance was made worse by the fact that once, just once Karyn had sucked his cock.
Craig made some 'mmm, mmm, mmm' noises as he drank more and more of Karyn's magical cum. Its powers soon became appearent when Craig began to transform. His hair grew longer, his skin soft and his figure female.
"This is just the beginning Craig. I'm not nearly finished with you." Karyn told Jon to take a picture. Jon held up his camera and pushed the photo button.
"There we go", Jon said, "a nice photo of Craig sucking your cock and turning into a girl"
Jon looked at the picture on the camera's screen. Not a bad shot. You couldn't see Craig's cock hanging below his legs. He may have been turning into a girl, but there was still some work to do. Jon wondered what Karyn was going to do to him next.
