Zoe mulled it over for a while, "Ok, I've decided", she said.
Jon and Karyn perked up, "What exactly do you have in mind?"
Zoe smiled, "Well I thought it over, I really don't want to risk permanently changing myself if Emily is going to hate it. So if it's ok with you Karyn, I want to borrow your penis for a while and try it out"
Karyn looked at Jon, "If it's ok with you, I'm not that fussed"
Jon shrugged, "Ok, fair enough. Did you want me to arrange the swap for you or what?" he said.
"No, I think I'll take care of that, may as well give these swapping powers a try", Zoe replied.
Jon and Karyn just watched Zoe, she was thinking intently and looking at the rock the same time, "I want this to be right, but I don't want anything to change, let me think"
After a moment, Zoe spoke, "Well, I think I have the wish now"
Zoe held up the rock and spoke to it, "I wish that I would speak the same wishes that Jon said in regards to his swapping wish", she said.
The rock glowed in Zoe's hands. Jon and Karyn waited intently for the outcome. In a few seconds Zoe looked around, she couldn't tell that anything was different, but she suddenly had an urge to speak words she'd never heard before.
Jon and Karyn watched as Zoe recited the three wishes that Jon made four years ago to give him the swapping power. Each time she completed a wish, the rock glowed in her hands, by the time she finished the wishes, and she just stood there, unsure of what to do next.
"Glowing means it worked, right?" Zoe asked curiously.
Jon nodded, "Why not just try it out?" he said.
"Makes sense", Zoe said standing up, she looked over at Karyn and pointed her ring finger, and "Give me that penis" she said.
Both Zoe and Karyn had a sudden surprise as the swap occurred, Karyn found herself with a void between her legs, similar to that which she felt yesterday when she and Jon swapped genitals, at the same time Zoe felt a very unusual sensation in her legs. She looked down and saw a large bulge in her skirt, pushing her panties and skirt out; it was hard to not notice.
Zoe walked back to the cabinet and put the rock back in the display and closed the cabinet behind her. She walked back over to Jon, looking proud with herself.
"I should get going", Zoe said, looking at the two of them, "It's been fun"
Jon and Karyn rose from the chair, they both took their turns embracing Zoe in a friendly hug before she headed for the door.
Karyn called out behind her, "Give our regards to Emily"
Zoe turned back to them as she opened the door, "Oh, I will"
"Have fun!" Jon added.
Zoe waved back at them as she walked to her car in the street, the door swung closed behind her. Jon and Karyn hugged each other tightly.
"Well, do you reckon she's going to be sick of it in a few days and want to change back?" Karyn asked.
"Did you?" Jon replied.
Karyn laughed, "No, I guess not, but she'd better give it back", she grabbed Jon's arm and pulled him towards the bedroom, "Come on, it's time for some fun", she said playfully.
As Jon was being pulled towards the bedroom, he asked Karyn, "How do two people do it with two pussies?"
"I'll show you", Karyn replied.
"Hey, she left her dagger behind", Jon commented as they walked past the table.
The both of them laughed as they headed for the bedroom.
