With many options at hand, you went to your short term memory for an idea instead. Of all the animals you passed, the donkey had been the most comical. Most of its fur had come off, along with ears and one eye. Compared to the jenny, the jackass had been in good shape. The jenny was mostly assumed to be that by the look of the male on her as it could have been any sort of equine at that point. And worse still, was the pathetic 'hee-haw' it made.
Feeling you needed to make it up to donkeys, for some reason, you choose the Jenny icon on screen.
First, you're treated to a box where you could put a name. Assuming this was some cheap build-an-animal machine, and knowing calling her 'Jenny' would be low hanging fruit, Klaudia pops into your head from nowhere. You type it in and are met with another option.
"Gestation period," followed by selections ranging from 'Infertile' to 'Standard' and various 'enhanced versions' which culminated in what was listed as 'Good Jenny 12' with it taking only a month for your donkey to produce yet another donkey. Knowing you wanted this one to be special, you make that choice.
"Experience duration," was the last question and vexed you somewhat. In the end, you reason it probably speaks to the quality of the stuffed animal you'll get. Since you'd rather it not disintegrate in your hands upon leaving the fair, you ignore the first option, 'Easy quick' and past even '6 births' to what was simply labeled 'Forever Bred'. Figuring the toy would have to be made out of titanium to last 'forever', you nonetheless take that option and are finally rewarded with smiling pixelated donkey. It winks at you and 'Processing...' reads on the screen.
You step back a bit and look for where the toy is likely to be dispensed and sure enough, you find a chute door leading to a rather crude bucket that was lengthened almost to a trough length. When a rattling could be heard from behind the flap of the chute and soon after, you get an unexpected treat. Feed is funneled in and quickly fills the trough. The dust in the air causes your nose to twitch as you back away.
Glancing back to the screen, you see a new message.
"Unexpected gender in containment crate. Resolving..." and the ellipses blinked continuously in a loop.
When you straightened back up, trying to think what it could mean, you noticed a wetness on your left inner thigh. It's already damp by the time you look down and see the stain down your left pant leg. That's when you become aware of your dick simply leaking fluid. At first you think it was piss but are more worried when the aroma of your own spunk is what greats you.
You shivered as you first felt a moment of pleasure from the expulsion of seed from your testicles but it faded into embarrassment and worry. Not wanting to undo your pants, lest you be seen by a worker or other patron, you simply feel around for the bulge of your cock. It takes a worryingly long amount of time to find the now emaciated and shrivel thimble of a cock you were now sporting while your testicles tugged up into your body, leaving your sack empty and hanging. You can feel it happening, but you can't imagine seeing it. Or wondering what was happening to you.
"Release submit Jack-four-five-thirty," crackles a vaguely female voice on an intercom you heard muffled through the wall.
Again, you were distracted by a pain in your crotch, that was somehow burning, itching, shivering, and almost arousing at the same time. The burning was your body parts moving to take on a new structure, the itching was the prickling grey hairs that were sprouting around the cause of the arousal. What had started with the slightly of holes had grown into a somewhat formed vulva, with testicles now pulling and changing to fit a new gender and species. All of this, to you, is just feelings and sensations, mixed with a blushing embarrassment over your lack of self control.
There was a clatter of hooves that startled you. Turning around, you didn't notice the 'Gender corrected. Beginning Jenny protocol' scrolling across the screen.
Instead your attention was on the shadowy creature trotting towards you. Heart pumping, you were starting to sweat. Your clothes started to get damp, and were beginning to show signs of tightness as your body gradually begins to add mass. You move back against the wall, about to start pounding when the figure comes into view. You laugh to yourself as nothing more than a donkey trots up, sniffing at the air, and just looking around.
You think that maybe this was the surprise and you expected to see 'Klaudia' tagged someone on the animal. You did find a tag, but it seemed to indicate a male. Glancing under it, you're definitely sure it's a male. It's pendulous balls hung low but were the size of grapefruits, with just six mottled inches of donkey cock hanging from its sheath. It looked thick as your arm which, now that you noticed, was looking rather hearty.
It was then that you nearly jumped out of your sneakers when your belt unexpectedly snaps clean off; taking most of your belt loops with it. Looking down, your gut and midsection, and thighs, had all put on considerable weight and even more, your bones themselves felt thicker. You're so busy trying to move without ripping your clothes, you don't even feel your ears starting to grow and even sprout their own dark grey hairs.
Despite your best efforts, seams in your jeans and shirt and even now your shoes were looking stretched to the near breaking point. The donkey seemed less interested, having turned his attention to the feed on hand.
"What's haWWWpenig to me," you say, unable to keep the odd gravely bray from cutting in. You had no idea they would be your last somewhat intelligible words.
Your shirt was riding up, revealing your gut and the dark hairs growing in gradually from your crotch.
Everything in your body is changing, racking your mind and senses with more than you can handle. You try and use the donkey for support but slide off and end up landing on your hands, leaving you on all fours. As if on cue, many things happened at once, leaving you dizzy and only able to watch it all unfold.
Your pants rip to shreds, while your pelvis and spine let out a series of loud pops and cracks to lock you onto all fours. You feel your ass cheeks spread in the open air, but the sensation is tempered but the wiggling tail that had sprouted from the base of your spine. Exposed as well was a shame you were lucky you didn't have to see. Your sex had changed genders but also species, leaving a swollen, dripping entryway to his new fertility. The puckered bestial asshole was simply the added piece of what made your back end look almost unmistakable from a Jenny, in heat.
Your shoes and socks finally gave way too, revealing your deformed, elongated foot with your toes merged into a black hoof. Looking away, you tried to shake your head out of what had to be a hallucination or dream. Instead you feel your ears, now long, hair and fit only for a donkey, wobble side to side.
You try and call out again, "HEEE HAWWW HAWWWW!" is all that comes out and you're reduced to whimpering. Even when you crack your eyes, which are looking down and under you, you see a leather udder forming, two teats taking shape. You quickly lose sight as your gut and ribs continue to grow more and more, forcing you to lift your head away. Your neck then started to hurt and trying to look back was all but impossible. Your head, save for the ears, was still human.
During all of that, you let out a spray of urine from your new pisshole, filling the air with an aroma that finally stopped the other donkey's eating.
Your hands cramped and arms realigned and grew, with the body below your still growing neck was now almost entirely donkey. And jenny.
You heard him huff and start to move around. You tried to move as well, but you were clumsy and slow, and he got around behind you. All you managed to do was see that nearly two feet of donkey cock was now hanging below the beast.
Heart racing still, you're forced to endure a moment of pain as your neck gains the proper muscle and thickness to support the changes soon coming to your face. All of a sudden, that pain seems like nothing to the heft of pain suddenly pressing down on your hindlegs. Your feet clatter as you try to stay up, unable to turn your head enough to see what was happening.
Then you feel his forelegs scrabbling at your sides fora grip. Then nipping at the dirty black mane you were still growing. Finally, the prod of something hard against your rear end. Your entire face goes a beat red as you feel the donkey trying to find its mark. You try to step forward but he tugs you back. Despite your new mass and size, he's stronger than you. Even with some slight movements, you've only managed to get yourself facing the corner and now truly being pinned.
You remember how long, and thick it was. The size of his testicles, and what they contained. You tried to reassure yourself that it wasn't possible. You couldn't take, no, not all of it. This couldn't be happening to you and this wasn't real.
All doubts were washed away when the Jack finally got in and forced every inch into you. The feeling took your breath away and left you wide eyed. All the better to watch your face finally starting to push out.
"AWWWWWW HEEEEE," you bray loudly, letting out a pained noise that wasn't all discomfort. Even when he was buried to hilt in you, you took it all. Your cunt clenched around the cock in a sensation you couldn't explain, but felt pulled towards. The jack quickly found a rhythm and proceeded to fuck away any humanity in your head, leaving your vision decidedly equine.
Head lowered shamefully, there was simply nothing you could do to stop what was coming. The donkey came inside you, and while only feeling the cock at first, you soon also feel yourself filling almost. Cum drips out of your backside as the jack dismounts.
You start to trot backwards, to see the damage, when your vigorously mounted again. You can't believe the jack's audacity until you realize the first one was trotting off while a second, bigger jack, was now mounting you too. Beyond him, at least seven more donkeys were standing in a row, cocks hanging drooping out from the smell of you.
Looking up at the screen, it's hard to read as yet another donkey's cock pushes into you. Still, what you can make out, in your dull, horny, mind, are the words, "Welcome to the farm, Klaudia." You can only bray as the second of many inseminations begins.
