Karyn held the rock and said "I wish, that for one hour ... "
"...Jon's deepest most secret fantasies would come true by me tempting him with them" Karyn wished.
Little did Karyn realize that she had just opened herself up to be the object of all of Jon's fantasies.
Standing before him, she now found herself fully dressed in boy's clothes, with a boy's body, but still looking like herself. It was as if someone had done a head swap on her. She found herself wearing a guy's shirt and pair of guy's jeans
A compulsion came over Karyn, and in a teasing voice she found herself saying, "So this is what turns you on, Jon? You want me to be more like a boy in so many ways, is that it, Jon?"
Mesmerized Jon replied, "Fuck yeah, Karyn. You make such a hot looking boy!"
"Then think of what you want Jon, and I'll become it" Karyn commanded.
A flood of changes began to overtake Karyn, and she unbuttoned her shirt to reveal her flat manly chest
Jon began to pant heavily as Karyn tossed her boy's shirt at him. Her flat masculine chest glistened with sweat and Jon moved toward her and took one of manly nipples between his teeth. Karyn moaned in delight as she pushed him away.
Pointing at the bulge Jon's hard cock was making in his jeans, Karyn continued teasing him, "So this the true Jon. Is this what really turns you on? Maybe you'd like me to be your own personal studly dancer"
Karyn pushed Jon down on a chair and then thrust the bulge in the crotch of her jeans against his mouth. Jon reached up and began to undo her jeans to pull them down.
"Oh "“ so you want a peek at my underwear?" Karyn said laughing.
Karyn's cock was now as hard as a rock and a dribble of pre-cum made a wet spot on the front of her boy's underwear.
Jon pulled his cock out the fly of his jeans and began stroking it as Karyn continued to strip and then laid down on the couch, her rock hard cock on full display.
"Does Jon want a little taste?" Karyn said giggling. Jon moved closer to Karyn and just as he reached to stroke Karyn's cock, she said "Uh-uh-oh! I detect that there are other things that turn you on"
With that Karyn's cock and balls retracted up inside her and she sat back and spread her legs, to show that she now had a pussy. The contrast of seeing her with a pussy and flat chest like a boy was driving Jon crazy and his balls were aching.
"Fuck damn! You are so hot with a flat chest, whether you have a penis or a vagina. Please Karyn, stop teasing, I have to cum" Jon begged.
"Oh no "“ I know you want to beg for it. So you can't cum just yet. Just keep thing more of your fantasies, Jon and I'll be them" Karyn ordered.
Jon's balls continued to tighten, and his mind was reeling.
"Damn right Jon "“ you want me to see my pussy in a jockstrap! Then you shall" Karyn said as she transformed. Her jockstrap was pulled down, her legs spread as she offered her pussy to Jon.
Karyn laughed, "But I thought you like cock, Jon!"
Jon was moaning, "It doesn't matter. You just make such a hot looking boy! You look so much hotter as a boy than you ever did as a girl and I so want to fuck you"
Karyn stood up and pulled off the shirt she was wearing to display a thick forest of chest hair.
As she began to pull down her jockstrap to reveal her cock, she made one last request "Which one all you fantasied about me do you want fuck, Jon? Your choice, and I'll be it"
