Intent on correcting the mistake, Karyn grasped the stone. "I wish that for the duration of the previous wish, the genital swap includes all appropriate adaptations I intend."
"I thought that you were just going to add your vagina to complete the swap", Jon asked?
"I started to, but then I thought: What about all the other parts and plumbing? I could never be sure I could specify everything, so I figured I go with intent. So let's make sure it worked, shall we?"
Feeling embarrassed, Jon slid his hand down between his legs, still half expecting his normal package, and gasped when he penetrated himself.
Karyn grinned at Jon's quick little gasp. "Judging from your reaction, I'd say it worked. Now where were we? Oh yeah, I was going to take this stick for a test drive. I intend to make you squeal."
Jon was momentarily disconcerted by the ease with which Karyn embraced and controlled him but analytical thought was washed away in moments.
Karyn wasn't sure exactly what to expect. While it certainly felt good, it was the indescribable feeling of domination and control that infused her whole being with each thrust into Jon that was paramount. Each thrust brought a gasp from Jon. Initially it was just a barely heard low exhalation of air, but each additional thrust brought a growing echo of excitement to her as Jon's gasps became more and more vocal, rising in pitch as Karyn slowly sped up. Somewhere along the line, Karyn lost the careful control she had over Jon and became focused on an undefined success that demanded that she go faster and harder while Jon squealed in high pitched mindless encouragement until an explosion of what might be described as an overload of delight mixed with accomplishment exploded out of her and into Jon. "Wow! That was different", she thought as she eased her weight fully down onto Jon and drifted off to sleep.
