Some *horsecock* assembly required
The face he saw immediately disarmed all of his suspicions. The ears were rather plucky and affectionate, the white fuzz on the small face and reddish blushing cheeks was adorable, and the bared tiny white body was streamlined and elegant.
Why had he come to this musky horse-smelling building? That truth had been forgotten like a distant dream. All he could do was stare at the lovely little stallion and feel an erection grow against his pants.
"The drugs should be working right now. You've probably forgotten a couple of hours of what you were doing before."
Forgotten what? He eyed the small sexy horse in a fog of delirium. Last thing he remembered was getting a call this morning-a call about what? He remembered it was about someone being ready to do something.
"Don't be afraid about that. We don't brainwash anyone here; they're just to make you more ammendable to the training and calm you for the physical portions of the process. For those who aren't dosed, the assembly line can be scary and quite painful."
He nodded dumbly, certain he hadn't been tricked into this situation-fully trusting that whatever he agreed to was one of those things he had forgot.
"I have the consent form right here. You agreed to do this, and I only force you through the process as you gave your rational choice when you were fully aware." The pony calmly remarked, handing it over for him to look at.
He did, recognizing his signature-if in a hasty excited way, before the pony carefully took it from his hands and put it on a nearby table.
In any case, he didn't need to remember anything to know that he had a sexual lust for the little pony and that cute white rump, long tail flicking about.
"Do you remember what will happen to you? We explain it in the article and in the contract since we know most probably won't remember the details anyway."
He shrugged, looking at the plain white door leading into the next room. He only knew that it would start in there.
The pony flirted his tail in a sexy way with a shy blush and simply asked; "Do you love stallions?"
When he nodded to this, the pony then asked:
"Do you want to make them happy?"
After he nodded again, the pony simply smiled with a cute giggle and said; "Then I'll leave the whole thing as a surprise to you."
The pony-who was half his size but still very cute and fuckable-led him to the door and in the next room was a black painted metal armchair.
"If you'll please have a seat, we can begin."
He did as asked and when the chair felt his weight, it warmed and vibrated in a comforting way.
Even as four cuffs slammed securely around his limbs and a padded metal belt came around his abs, he was still massaged and melting calmly into the chair.
"Remember that the process is reversible-people just don't want to reverse it." The pony mused with a knowledgable grin before turning some switches and buttons on a wall control panel.
He watched the frame slide up out of the chair like a skeleton and lock securely in place in a tight dark space. Up ahead, random mechanical tubes glistened in chrome dyed silver.
He clacked forward, restrained in his simple 'H' shaped thin pole bonds as the plucky little stallion waved goodbye, lovely cheekbones now red with shyness.
Inside the machine, things were dark like a cave with the occasional peek of illumination. It also proved more cramped and tight than he liked. The assembly line slowly brought him into a dark mouth with jagged metal teeth whirring with pistons and cylinders for various pumps.
The first unwelcome surprise came from above-faucets flooded him in a pungent bitter liquid that ate his clothes and every strand of his hair.
Almost all of his hair-he felt as the frame-which had him positioned spread-eagle bent him helplessly over at his waist and raise his butt high into the air like he had been tied over a step ladder for a good fucking. Instead, he felt as two cold sharp talons grabbed his asscheeks followed by a short burst from a hose right at his butt hair and left him so bare and cold, that he couldn't forget he had been stripped of everything.
Even if he had been physically revealed, mentally, the process had only begun as he was sprayed all over to remove any trace of the caustic fluid from his body-droplets smacking his raw bald head like hammers.
He wanted to cry. All of this was so humiliating and he found himself wondering why a stallion would want to do this to anyone if they loved to play with humans so much.
All thought was driven from his mind as he felt the frame make him bend over as if for a spanking and he almost panicked when a small thing slickly wiggled into his ass like a greased finger and began to slowly pump fluid into him even as it inflated itself to make shitting impossible. He felt his rear fill to the brim before the probe deflated and shot from his ass in a blink as he emptied his overloaded hole all over the tracks and floor-helplessly dragged forward on the conveyor belt to the gleaming arm ahead. He passed under it and no sooner did he stop than he felt the long thin anal probe slide into his lubricant-enema leaking asshole-fucking his greasy hole for at least ten minutes-stopping and shooting a little bit of warm lube into his asshole as if it had cummed in him.
His loosening hole spasmed and sucked desperately after the hard dildo as it slid easily out with a squirting trail of sloppy smacking noises. A final silent little pop and his ass was unplugged, oozing out long thin streamers of veterinary hand lubricant that looked somewhat like gooey raw eggwhites.
On the right came a slowly encroaching swath of white light starkly into his unaccustomed eyes as the machine spun him slowly toward the opening ass first still bent over.
He wasn't able to look back, but he knew there was a stallion poking and prodding his ass with cold gloved fingers like an inspector grading a 'rump roast', the occasional thick cock-sized finger slid easily into his sore well-used hole as the tips of those fingers were used to feel ever slowly and gently around his anal rim before they were removed.
His ass impatiently milked every finger senseless as the last gave him a few hard thrusts and vacated-leaving his ass unused for a moment as he heard some clicking behind...
Then his ass exploded with mare heat as a long thin hot object was rammed into his ass and held there as he repeatedly sucked on it with his nether muscles for all he was worth like the little slut he was.
A loud beep sounded off; some kind of signal-and then the rod was removed from his ass with one hasty zip as a loud click snapped off and he was forcibly turned and moved further down the processing line; asshole soggy with lube and beginning to chafe and rash over from all the moisture even as the assembly line stopped him again and shoved an even thicker dildo into his ass that felt as big as a fist, but probably wasn't so thick.
The tapered end began to burrow at his hole and sunk easily inside him with a sensuous slide and wiggling vibrating squirm of rubber over a flexible metal tentacle as the machine dick began to rape him ever emotionlessly with pleasureable rams into his ever loosening hole. Where it had hurt at first with soreness and the popping of overextended anal muscles, his spincter now widened like a rubberized mouth and began to engulf the fake member as easily as the fingers that had tortured it earlier.
He couldn't believe how helpless he was to the pleasure; his mouth hanging open and drooling in bliss as the pistoning machine-cock used him and performed its job with oiled precision ease. His anus almost seemed to flop open and outwardly in a goatse as the thick thing expanded, squirting J-lube into his ass as copiously as a horny horse's questing member.
It was over too soon as his eyes closed in delight and the snake of pulsating machine dick left his squirming needy ass with one last jet of lube-cum, the juice leaking out of him and mixing with the other lube already in his body.
His eyes lit up in shock as an even thicker cock-like object invaded him suddenly and pushed through his ass so painfully, it felt as if his ass were on fire. It shot a long hot jet of lube into him, locked in his body for a moment, and then left-his ass now unblocked and dribbling the lubricant enema in a maregasm-like way of afterglow as his cock stiffened and lengthened a little more than it had.
It was strange; he noticed that his cock could increase in size a slight amount if he were REALLY horny; like fiery flaming horny.
His body shuddered helplessly as the machine moved him into the light again, where his defenseless ass was immediately turned toward an opening where another stallion working in the factory would do something.
Immediately, he twitched and spasmed in pain as a buzzing needle began to wander over the skin above his buttocks in an arcing pattern, seeming to trace several letters or something. As the stallion stung him over and over with this unseen stylus, he knew he was getting tattooed.
It stopped, giving him a brief moment of respite from the pain-
Then an even worse agony coursed through his body as he felt something hot burn his right asscheek. He panicked and fought against his cold immovable restraints-
He was getting branded!
After it singed his skin for what felt like eternity, he heard another button and was turned around to go down the line to the next step.
The sudden shove of thick cold rubbery pony flesh caught him by surprise and made the fresh brand sting even more. The fake pony cock raped his hole without mercy; nearly making him cry out. It worked into him ever so deeply with every throbbing thrust of motion and soon filled him ever completely with fake flesh like it belonged there. After the member came in him for what seemed like a gallon of juice, it yanked out of his ass with an eruption of 'cum' from his ass like a cannon shot; his ass leaking in such a way it would probably never feel dry again.
Even with the calming sensation of the drugs, this was still a confusing ordeal! Some parts felt fantastic, but the others were so uncomfortable and he didn't know why they were happeing. Did he agree to being permanently marked? He couldn't remember.
No sooner had the pony organ left his hole, than a metal buttplug as thick as a draft stallion fist was stuffed up there to take its place. He shuddered as the cold giant thing touched his asslips; the plug sinking neatly into his anus and making itself home.
Immediately after getting stuffed like a sex slave turkey (like so many times before), two plastic objects immediately fastened over his body. One sucked his penis and testicles into some kind of airtight enclosure which disengaged onto his crotch as if a plastic leach, and another plastered itself to his face that had a breathing hose attached. No sooner had the machine prepared him than he was slowly and fully dipped into a warmed dip of some kind of thick slurry-his entire body dripping with the strange mixture as he was removed from the bath and the different attachments slowly removed from his body as it dried.
Except for the buttplug-
He felt as the strong pull of a magnet quickly yanked it out despite his ability to squeeze his butt against its flared thick body. It erupted from his ass with a sting of horrific pain with a loud bang against the metallic magnetized pan held right by his bared rear.
Another machine arm snapped a long white silky wig over his head and a long white pretty horsetail against his ass below his tattoo.
As the slurry of juice hardened all over him, he felt he could move even less and soon found himself trapped in a cocoon of plastic that trapped him completely. He could barely breathe as it dried and hardened rigidly around his chest like a corset.
But it didn't end there; another coat of some kind of chemical sprayed all over his body-it melted into the plastic, and though it was just as hard as when it dried, it somehow made his skin super sensitive and he felt everything touch his plastic body like nothing he had felt before.
He came out into a dimly lit little hall of mirrors where he could see every part of his body.
The pretty tail, the tattoo that said 'Mare Slut' in Italic lettering, the brand that had a horseshoe and 'Property of a Stallion Master' circling it like an official title.
His body blushed an involuntary scarlet when he realized a huge horse master was going to be taking him home and using him as a sex doll.
The last part of the assembly line stuffed a huge pink horsedick into his ass and locked it into place since it was built with a buttplug neck to keep it burried. He drooled in embarassment as his anal muscles pushed and played with the monster thing inside him even as the robot arms slid pink silky panties up his legs, a pink frilly dress over his head, and covered his face in different makeup as a giant shadow loomed overhead and smiled with white horsie teeth.
"That should do. His master will definitely be pleased with the transformation." Came the voice of the little pony as he fell soundly asleep from the tiring ordeal.
He awoke later in warm fuzzy naked dark chestnut arms as a soft muzzle nuzzled his face.
"How are you hun?"
Looking up nervously, he remembered the tender face of his mate and smiled. "I'm fine; a little stiff."
Furry hot arms caressed his body, reached under his pretty dress, and began to play fervently with his cock and wiggle against the giant horsecock dildo drilled obscenely into his hole like a slick thick worm.
"You wanted to be a doll, and I thought it was hot as well." The sulky passionate creature remarks, brushing his new white hair with a pretty coral pink currycomb. "The manager said that the plastic is too thick for average humans to bend, but a strong stud like me can easily position you in whatever way I want-like a pretty poseable action figure."
The human blushed, remembering his humiliating new body marks and knew without any doubt he was a 'mare slut'. Even dressed for submission, he just lay there and let the experienced hand play with him.
"Dirty little dolly mare, aren't we?"
"Yes." He mused simply, allowing the big pretty horse to play with him.
