Yes.

“I guess I am ready.” You answer more curious than anything.

“Normally when I want a new slut **** I have to break the person down then build them back up. It is a long and painful process, but it works. Now here you are asking for it.” He walks closer holding something behind his back. Once he is behind you he continues, “I suppose I can go without the pretense of science if you really want it. Do you really want it?”

“Sure.” You say, not really sure what the hell he is talking about.

He sets down a brown leather satchel and moves the tray with the makeup out of the way. “Fine, you shall have it. Lie on the stool on your stomach then grab your knees and pull yourself into as tight of a package as you can but don't touch the ground with any part of your body.”

A little afraid that he is going to fuck you up the ass, you do as you are told. It is rather uncomfortable, but you manage using the rungs of the stool to keep balance. “Like this?”

“Perfect. Now hold it and don't let yourself hit the ground. This will take a few minutes.” He then circles around you pouring what you decide must be gunpowder or something in a circle around you as once it is done it bursts into flames. Next he uses the same powder to draw sever symbols around the burning circle, then as these burst into flames as well, he rings these with a second flaming circle. Once finished you can see him mouthing words, but he doesn't make a sound. Which you find very odd because you can see him exhaling in what should be shouting, but you can't hear anything but the dull crackle of the fire.

The soft caress of a small hand sends a chill down your spine as it runs down the length of your body stopping to rest on your ass. A feminine voice says, “Nice, I accept your manhood as sacrifice.” The voice is a bit hard to hear as the crackle of the flames seems to drown out everything. Then suddenly the voice rises to full volume as the flames suddenly vanish, as does all of your surroundings and you find yourself lying on red satin sheets of a large pillow covered bed. “I shall take your manhood from you mortal, but don't worry if you can resist, you may survive.”

“What?” You ask rolling over and looking to see who is behind you. But the hand on your back proves to be far to strong and you are unable to roll over.

“Shhh. Not just yet.” Then a finger from her other hand probes into your tight asshole causing you to grunt. “Mmm nice and tight just like I like it. I am going to enjoy this.” You can feel her body press down onto you as she climbs onto your back, her hot breath tickles your ear as she first licks you then whispers, “The longer I fuck you the more feminine you shall become. The only way to fight it is to fuck me back, for every contact with my cock causes parts of your manhood to fade away as I take it from you. One hour is all I have you for, so shall we get started?”

“No I don't want to get fucked.” You say, panting, her every touch of her hot body causing waves and ripples of pleasure to rip through your body like a ****. Then her finger slips out of your ass and is replaced by something much larger, “Oh god don't do....” The head slips in and something electric jolts up your spine, “Oh my that is so fucking big. Are you really going to put that in me?”

“Shhh be a good little girl.” She whispers licking your ear. “Your ass is the key to changing your size and structure, the longer I fuck this hole, the smaller and more petite you become.”

The pressure builds and an inch slips in, the wave of pleasure is unlike anything you have ever felt, your cock rises to attention in an instant and spurts a small blast of cum up your torso. Her cock digs deeper, your body giving in and opening the passage for her long intruding member. Finally as you feel the tickle inside, as if her cock was caressing your spine, her body presses warmly against your ass, her entire length sheathed within you. Her hard nipples dig into your shoulder blades as she clamps tightly onto you and begins bucking back and forward fucking you with hard short strokes only pulling out a few inches with each thrust. You can't believe yourself as you lie there biting into the sheets, grunting and moaning. As she pounds away something else starts to become apparent, slowly you notice her body seems to be getting larger, as at first she was just on you, yet more and she is riding you. “Oh god this can't be real.” You finally let out and try to resist finally, pushing off you lurch backward, impaling your asshole as you do, but you do manage to buck her off of you like a prize bull ride. Spinning on her you see a magnificent creature, she/he is most likely nearly 6' tall with massive bat wings, a serpentine tail with a bulbous head, long lean legs, tight sexy torso with impossibly perky DD breasts. Her face is a work of art, angular features in symmetrical perfection with piercing deep blue eyes and a mop of long deep red hair. The only thing not quite right is the 12” thick cock hanging between her legs.

She smiles a wicked smile springs back on you and takes your head in her hands. She kisses you deeply then whispers, “Your mouth is the key to your femininity, the longer I fuck it the more voluptuous you will be, your breasts and hips will swell, and eventually your cock will shrink till it transforms into a pussy. Then that will open the entry to your mind, fucking your pussy will make you crave and worship cock.” She pushes you down and you can't resist a taste taking her thick member into your lips. As you drink it down deeper and deeper, taking it down your throat as if you had done this a hundred times before, you can feel your chest swell just a bit, your nipples leaping to attention first becoming feminine in an instant. She draws back and fucks forward fucking your throat for several seconds as you succumb to the bliss of being taken by such an amazing creature. Your breasts swell to tiny little A cups, and your hips widen a bit to give you a sexy little hourglass figure if still mostly masculine before your mind rebels and you push her back.

“Wait I don't want that.” You yell, but staring at her beautiful form how can you not want her inside of you.
