As madame was finishing up for the day and was leading everybody to the their establishments she saw one of the young contestants (looked around 15) looking and playing around with one of the harnesses made for the horses.
Madame was intrigued by him and closed the distance while saying:
You're kind of young to be here.
The boy was startled by her coming from behind and answered rather quickly.
I...I want to be here!
And why is that? Have you come here to be turned into an animal?
No quite..., howeverI would much rather pull heavy objects around as an animal then as a human, I would like to become a new species.... One that would merge the genetic boundary between humans and horses while still being able to plow.
Well that's a lot of fancy talk!What do you really want boy?
I want to be turned into a horse just enough to be able to pull a plough.
A new species huh!
It is doable, however, beware... You will live mostly the life of an animal.
Do with me as you see fit, I want to be the first of a new species.
OK boy, come with me,she said.
Wait now, it's in the middle of the night....
That's when new species are born, by Dusk you won't be a human anymore, nor an animal.
As she said this the boy followed her to the main gathering area and was greeted by a wooden contraption right next to a shoing post for horses.
As he saw this he was placed on the wooden contraption with his feet dangling down and Madame right next to him saying:
Lets begin!
As she said she applied a generous amount of a cold gel like substance on his back legs as she began chanting and pulling them downwards.
The boyslegs started elongating from his heels downwards quite a considerable amount while his femurs were becoming a bit shorter. His lengthening feet resulting in his cannons being formed shortly followed by a numbing sensation in his toes. After a while he couldn't feel them at all, it was like blood had stopped flowing to them and his sense of touch had stopped, he couldn't even move them anymore. As this was happening he looked at his toes or what used to be toes only to see his outer most toes being reabsorbed back into his legs and his 3 central toes fusing into a solid bone that eventually produced another joint and then 2 black keratin hooves sprouted from his once nails.
Made wasn't done however and moved on to his arms or soon to be forelegs.
She spread the se cold gel on his arms as he was getting arroused more than he had ever been in his life,the cold gel fueling into the anticipation of what was about to happen to his hands.His hands started bulking with a small amount of extra muscle while his wrists started elongatjng and becoming the main transformation area. His upper and lower hand did elongate, however it was nothing in comparison to what his hands needed to go through in order for his backlegs and forelegs to be at the same elevation.
His wrists started elongating and his metacarpal bones started fusing together to create a more sturdy bone structure, something that wouldn't break as easily as a flimsy human hand. His thumbs and his pinky fingers just started to be outgrown by the resulting sturdy legs and at some point just were absorbed after being carried downwards with his extending forelegs much longer then they should have.
The final nail in the coffin was when the same numbing started to settle in his fingers, he tried to wiggle them and see for how long he could feel something in them, however to his surprise he could only move his remaing fingers forward and backwards due to the tendons responsible for intricate and fine motions having been replaced with more sturdy basic ones that performed much more rudimentary jobs.
His remaining fingers melted and fused together while he was still trying to move them back and forward, however eventually the bone structure fused as well turning into a single column of bone and cartilage,while his useless nails started gaining a lot of mass and eventually turning into pitch black hooves. The act of endesly trying to tell your fingers to open and not accomplishing anything was very arousing to him. This was the first time when he tried to flex his new forelegs,resulting in them only being to move under him a moderate amount, as for what was left of his wrists turned hooves they could only bend back a small amount.
He was getting increasingly aroused over not being able to do anything to open his hooves and feel anything besides the wind on his uncovered skin.
At some point he tried to get rid of his arousal by grabbing his member, however that didn't get him very far, as he became even more frustrated and settled on moving his member by moving one of his back legs to create motion.
Just as he was about to come Madame stopped him and fixed his member to his stomach and held it there while chanting. The result of this was that a burning sensation was felt between his member and his stomach while the head of his member flared out, elongated and became thick enough to be considered a monster by human standards and small to average by horse standards.
After this was done Madame applied some gel on his ass and after further fondling she slowly but surely elongated more and more of his spine. His new tail got a coating of black hair and started hanging limply downwards.
Once this was over, Madame took him off the stand and said:
You're finished! Actually..... No as she came up to him she started pulling up his ears to the top of his head. Due to having pulled them from the edges they also became more pointed and could also rotate around.
Now, you're done! I will call you: HomoEquis.
There you go!
He was so excited about this that his member elongated out of his sheath as he tried to reach it with both forelegs and hind legs,however he was only able to make that up and downotion with his back leg to move his member.
He couldn't believe it he...he he had hooves and a tail and was down on all fours.(talking to himself).
As he was thinking this he saw an old door that was rested on a wall and his hooves started claking out of anticipation as he wanted to kick it like a real animal would.
He positioned himself with his forehooves down looking right at what his limbs have become and what they were resting on and then he started bucking against the door, each clack connecting in a way his body didn't think it was capable of.
He started getting increasingly aroused while looking down on what his hands had become and how they were digging themselves deeper into the earth with each one of his bucks.
He wanted this, he needed this he had to have it as he started kicking the door more rapidly with his member slapping more on his belly he couldn't take it anymore.
Madame made a gesture while looking at his neck and snapped her fingers as the boy on the edge of his orgasm started braying: HE HAW! HE HAW! HE HAW! HEEE HAWWWWWW!
As he was braying his forehooves started digging themselves deeper into the ground and then he could take it anymore!
HEE HAW! HEEEE HAAAAWWWWW!
As he came his dick started splattering his load onto his belly while he was still kicking the door with his back legs one strike more powerful then the other while non stop braying: HEE HAWW! HEE HAWW!
Hee Haww! He Haw! Haw Haw haw haw.
The boy eventually stopped kicking the door leaving his hoof prints clearly visible on the wooden door. He was still lightly hawing as he was catching his breath with his belly full of his splattered seed and the ground equally so.
He took a few steps from the door and layed down on the grass on his belly as far as his backlegs allowed, with them being on the side and his belly on the ground driving his member into the grass and looking at his forehooves which managed to get splattered as well as he fell asleep in the cold grass.
