Jon took a deep breath and started his tale. "So I had a fantasy and I started masturbating in the upstairs bathroom."
"Was it this fantasy?" Karyn asked. As she sat right there on the leather couch, her bikini top and miniskirt morphed into a black-and-white latex version of a skimpy maid's uniform, her long blonde hair somehow styling itself to be piled atop her head, her clear acrylic platform shoes changing into a slightly more reasonable pair of black pumps. Her makeup and jewelry changed not at all, so she looked not at all like she'd do any actual maid activities. "And why were you jacking off by yourself? Why didn't you call me?"
"I-I'll get to that," said Jon, stunned by Karyn's wardrobe change, although realizing that it seemed completely appropriate for this porn world.
"You look tense," Karyn pointed out, reaching over and pulling down Jon's zipper, then fishing out his cock to begin a handjob. It was already thickening into an erection.
"Uh, I wanted to wish for my fantasy to come true, but just in case, I left myself an out, so I wished that when the conditions were fulfilled, things would go back to normal."
Karyn was now using both hands, one stroking Jon's shaft and the other gently caressing his balls. "Okay, but I can't imagine you wanting to reverse a fantasy-come-true wish, any more than I'd ever want to go back to only being a C-cup."
Jon wondered if a C-cup was the minimum breast size in this world. "Well, my fantasy was -- I'm not sure if you'll know what this means -- I wished the world were like the kind of porn I like."
Karyn's hands actually stopped moving as she narrowed her eyes. "You're right. I don't know what that means."
She leaned over to spit some of her lubricating saliva onto Jon's cock, and continued her ministrations as Jon said, "Porn -- pornography -- it's, uh, something that causes you to become aroused. Uh, pictures, or video, or even stories --"
"What are you talking about? 'Become aroused'? When are you not aroused?"
Just as Jon had feared, Karyn didn't seem to be getting it. He wondered if he should wish that she remembered the old reality -- or maybe he should wish for her to forget this conversation, and get to those other wishes she'd wanted to make.
