I stopped chasing Zoe. Unsure what to do, I tried to cover my huge tits with my hands, and stared at Karyn. Since she appeared to be totally naked to me, I don't know why it was so embarrassing to be totally naked in front of her. Maybe I was just humiliated by my lack of control over my own thoughts.
Karyn started to laugh. "Fuck, Jon - I leave you alone for an hour and I find you chasing your sister around the house, buck naked, with huge boobs and no dick! What is up with you?"
I felt my face flush red with embarrassment. I also felt a strange, wet warmth emanating from my crotch. Holy crap, was I ever getting turned on by this!
Karyn looked at Zoe. "Zoe, are you recording this?"
Zoe put her phone away, and said "Maybe," with a sheepish grin on her face.
"That's cute. Did your brother explain what is happening to him?"
"No," said Zoe, "He said he had some kind of curse, but he wouldn't tell me how he got it."
"That's because you..." I started, but Karyn cut me off.
"It's not a curse," she said. "Not really. He actually wished this on himself."
I did NOT want Karyn to tell Zoe about the stone, but I was too slow. "Karyn, don't tell her..." I said, but Karyn interrupted me again.
With a snap of her fingers, Karyn said "Jon, concentrate on having no vocal chords for a minute, will you? And sit down, or else I'll think of something worse for you to concentrate on."
I tried to speak, but I couldn't make any sound other than the faintest of whispers. Karyn pointed to the leather couch, and I went and sat down, obediently.
"Don't tell her about what?" Zoe asked.
"The wishing stone," said Karyn, reaching into a backpack she was holding. She pulled out the stone and held it up. "Jon forgot it at my house. It grants wishes, but you have to be careful or else they'll be permanent."
"It grants wishes?" Zoe said, her eyes widening.
"Yep, let me demonstrate," said Karyn. She held up the stone and said, "I wish that the outfit Zoe is wearing right now would change into a bikini."
The eye-twitching sensation came over me, and when I looked up, Zoe was wearing nothing but a black bikini.
"Holy shit!" said Zoe, looking down at herself. "Have you guys been using it much?"
"Yeah," said Karyn, "A little. I accidentally wished for big boobs and long blond hair."
"That's not your natural colour?" Zoe asked.
"No," Karyn explained, "and that's another thing about the stone - anyone who doesn't hear the wish thinks that that's the way things have always been."
"Wow," said Zoe, "but what about Jon's curse? I didn't know about that."
"No," Karyn said, "I assume that, since it only affected Jon, he was the only one who knew about it. Same as with his OTHER wish." Karyn glared at me.
"What wish?" said Zoe.
"He wished that he could see me naked," explained Karyn, "So no matter what I'm wearing, I always look naked to him."
Zoe laughed, and then her eyes widened. She covered her chest and crotch, looking at me.
"Don't worry, he didn't wish it about anyone else," said Karyn. "I wished to know what Jon had wished, and it was just that and the thing where he can change his body by concentrating on it."
Zoe relaxed, and then asked, "If he has to concentrate, why is he so suggestible? I got him to do this," she waved towards me, "just by talking about it."
"Well," Karyn smirked, "I may have made a couple of wishes about Jon while he was heading back here..."
My jaw dropped. Zoe said, "What, exactly, did you wish?"
