"Transform," Kyle finally blurted out. Instantly, part of him regretted it, but choosing one was better than getting both, and surely that mousey little twerp couldn't think of anything too bad to do to him, right?
If only he knew.
Jen chuckled before responding. "Really? Well, Kyle Smith, it's your lucky day! When I'm through with you, you'll be the most attractive person at school, and you'll have all the pussy you ever wanted!"
This was certainly not the response Kyle was expecting, but he knew better than to assume anything positive.
"Okay, then," Jen continued, "for your transformation, your body will become almost entirely female, except that your male genitals will remain. However, your head and neck will disappear, and between your shoulders, you'll instead just have a vagina."
...What the fuck?
"Oh, I'm not even close to finished. First off, your brain's functions will be fulfilled by a spherical core in your chest, near your heart. As for your senses and consciousness, you'll be able to see, hear, and smell like your head was still there, and you'll taste things with your genitals." Jen had initially wanted Kyle to have to literally think with his genitals, as sex was generally the only thing he ever bothered thinking about, but this would be a decent compromise. "You won't be able to talk, but you'll use telepathy with anyone close enough to hear a normal human voice. You won't need to eat, either, though you'll want to have sex or at least masturbate once every day or two. Not that that'll be hard, since you'll be a sexual being now, and people will expect you to be fucking in your free time.
"As far as anyone's concerned, you're still a dude, and they'll treat your changes as though you just got a haircut or something. Any women who were attracted to you will still be, though you'll be giving off some pheromones that might influence everyone else to want you. Your own sexuality should only change a little: you'll like women almost exclusively, but you'll tolerate men just long enough to transform them."
Jen paused, and Kyle heard a slapping sound. "Oh, dammit, I almost forgot! Whenever you do fuck a dude, he won't be a dude much longer; you'll end up turning him into a creature like yourself. They'll work pretty much just like you, aside from some of them being more traditionally futanari at both ends, and they'll be treated the same as you are; the only thing is that they can't transform more men nearly as easily as you can, unless you explicitly want them to. As much as I wouldn't mind this spreading out of town, I'll leave that decision to your horny ass."
Kyle heard a sigh on the other end of the line. "Okay, I dunno what else... No one will care how you or any other transformed men dress, so if you want to keep wearing the same clothes or go nude or whatever, go ahead. You don't even need to cover your "head" if you don't want to, though I'd consider it."
After another pause, Kyle had had enough. "Okay, I get your batshit sexual fantasy now, so are we done yet? I'm late for class."
"Sure thing, stud," Jen mocked. "Try not to have too much sex today!"
After a second, Kyle heard her finally hang up. "Great," he thought, "now I'm even later thanks to that crazy perv bitch. Better not lose my head over this, though, right?"
