"You don't seriously believe in this stuff do you Kyle? God you're such a dork."
Jen could hear the smile on Kyle's face as he replied "Oh yeah? We'll see who's the dork. Since your time's up, you get both!"
Kyle paused for a moment to think, until he had a flash of inspiration. "That's right, a dork, the complete opposite of your current self. Jen, you're the hottest girl in school, you can get with any guy you want and have sex whenever you want, you're super popular, and you hate me with a passion."
"What's your point, freak?" Jen snapped, blushing slightly at Kyle's accurate but flattering statements.
"Let's reverse all of that." Kyle sneered. "For the first part of your transformation, all of your clothes will disappear so you can properly appreciate what's about to happen to you."
"As if, you perverted little f-" Jen began, but she was interrupted by the surreal sensation of her clothes disappearing into thin air, leaving her stark naked. "What the fu-"
"Next," Kyle continued, clearly enjoying the shock and horror in Jen's voice, "You're going to lose that hot bimbo figure of your as you turn into a plain, underdeveloped nerd girl, with all the prerequisite nerdy interest and hobbies. You're going to be a stereotypical little dorklet, the total opposite of your usual self."
Jen could already feel her curves melting away as her body began to narrow. She felt her long blonde hair shrinking and shortening as it darkened and turned brown, eventually settling into a plain and neat chin-length bob cut, held in place by a cutesy hair clip. She realized with horror that her prized E-cup breasts, the envy of every girl in her class, and her secret weapon for attracting boys, were beginning to regress. Jen cupped her precious assets in her hands as if trying to physically prevent them from shrinking away, but it was hopeless, her once proud and jiggling tits gradually receded away until she was left with nothing to grab any more. Her chest was now barely even an A-cup. Practically flat. Combined with her narrow hips and body, with only the barest hint of a feminine curve her figure was practically boyish.
Jen was furious, "What the fuck have you done to me? Fix it now or I'll... I'll..."
Kyle interrupted, "Oh no, we're not done yet Jen, we still need to fix that attitude of yours. You'll now turn into a total nerd, your confidence will melt away, especially around me, because..."
"B-because?" Jen stammered, suddenly feeling much less fierce.
"You're totally in love with me." Kyle continued, "it's a hopeless, desperate crush. You're so in love with me that you only have eyes for me, even my voice alone is enough to get you desperately horny."
Jen realized that this was true, Kyle's voice was making her feel really warm and fuzzy inside. Hot, even.
"That's right," continued Kyle, "Just thinking about me gets you so incredibly horny..."
Jen's hand found its way to her crotch, and she began to rub at her slick, wet slit, feeling tingles of pleasure. Kyle's voice was so hot, she couldn't believe she was actually talking to him...
"But it won't be easy for you," said Kyle, "I'm taking away all sexual sensitivity from your pussy and transferring it to somewhere else."
As Kyle said this, Jen realized that rubbing at her wet pussy was no longer getting her anywhere, it was about as erotic and pleasurable as rubbing the lips on her face.
"As horny as you get, masturbation won't help you any more. From now on, you can only achieve sexual pleasure and orgasm from getting fucked in the ass. Good luck with that!" Kyle laughed. "Well, I think that's about it, I'll see you at school tomorrow. I can't wait to see the new reverse Jenny." And with that, Kyle hung up.
Jen, now Jenny the dork, stood in complete shocked silence. She was still burning with lust after hearing the voice of her beloved Kyle, but no matter how hard she rubbed her pussy, she couldn't feel any pleasure or release. It was even starting to get sore from her efforts. She noticed that her room had changed. The walls were now decorated with posters of Japanese idols and her favorite 80s anime, Sailor Cutie Kitties. Her shelves were stacked with retro gaming consoles and expensive anime figures. (rare collector's editions, Jenny noted with pride)
Not knowing what to do with this mixture of fear and lust building up within her, she threw herself onto her bed, clutching a plush figure of Pyonko, the fairy animal mascot from Sailor Cutie Kitties.
"He actually talked to me, Pyonko. Kyle Perkins talked to me and said he's looking forward to seeing me tomorrow!" Jenny lisped in her nerdy new voice. She still felt horror at what Kyle had done to her, but it was being overpowered by her newfound hopeless lust for him. She began to dry hump her bed as she clutched Pyonko tightly to her chest, but her useless gyrations did nothing for her pent-up sexual frustration. "I can't wait to see him..."
