This one's commission for FA: hairymage

It's a story about Dawnheart, who's somewhat the runt of the herd and who's often bullied because of that. But it all changes when he finds an idol of virility that gives him the power to steal size from others...


Dawnheart could still hear the laughs of the other stallions that were trotting away proudly, leaving him holding back tears as he lied in a puddle of mud. The Shire horse's white fur was covered with soil, water and mud and his blonde mane was matted and messy. A few moments after the other members of the herd were far enough from him, Dawnheart tried standing up and took a few moments to stabilize on his four shaky legs. Every time he thought he had gotten used to this humiliation and bullying, the other stallions' cruelty brought him back to reality. Almost all the horses in the herd were mocking him for his lack of muscle, for his slow galloping or for his unremarkable looks. Dawnheart was a scrawny stallion, standing at four feet tall at the withers, had a plain white robe with a messy blonde mane, and he hadn't good stamina nor power in his legs. He was leagues away from any of the three bullies, who all had something exceptional that he completely lacked.

Feeling particularly depressed, Dawnheart began walking very slowly with his head hung low towards the barn. Thanks to his small height, the white horse was able to walk behind the wooden building. It was cramped, but he liked going there because there was a hole in the fence of the enclosure, a hole that was just large enough for him to slip outside when he needed to escape. Like many times before, Dawnheart considered leaving and never returning. But every time that he went, he got scared of becoming food for the wild wolves and bears that lived in the nearby forest, and thus always came back. He knelt, stepped forward and wiggled his way through the hole in the fence and once he was out of the enclosure, began walking away from the farm. Wandering away for a while after the particularly rough humiliations like the one he just went through was something that he liked to do. It didn't help at all with the problem, but at least he didn't have to see his bullies. He always used these small strolls to re-live the bullying, except that he'd reverse the roles and he'd be the one humiliating the assholes.

Today's walk was particularly long for Dawnheart, he explored a part of the mountain that he had never gone to before. While trotting on a path full of rocks and pebbles that was difficult to walk on with his hooves, he spotted a small natural tunnel in the mountain. Thanks to his small build, he was able to squeeze through the passage in the rocks, making dust fall down the rocky path as he went down the way. When he reached the bottom of the tunnel, there was a small cave that looked like it had been carved out. There were flickering flames coming from six candles arranged in a half-circle pattern lying on a sort of stone altar at the middle of the small chamber, lighting up the walls with their flickering faint light. Dawnheart looked all around the place, fascinated by his discovery. The stone wall was covered in weird symbols and pictograms of all sizes and shapes. On the altar-like boulder was resting a small idol shaped like a man hugging two large cylinders, casting shadows on the wall behind it. Curiosity got the better of Dawnheart, and so he approached the trinket. As soon as his snout passed through the ring of candles, a giant spark appeared at the top of the statue,immediately jumping at his nose and startling him. As he was pulling away, the flickering flames of the candles expanded to form a sort of screen made of fire. The white horse whinnied in fright, moving backwards and hitting his behind against the stony wall, weakening the cave's structural integrity. The fire danced and split in two, forming two distinct images for the stallion to see. On the left, there was a small horse made of fire and sparks, and on the right, a shape very similar to that of the idol he had seen. A spark went from the magical trinket to the horse, then the artefact faded and the horse began backing up. The fiery show continued with a new image of a large stallion appearing into the air, who then pranced around the smaller one for a couple seconds. As soon as the big one stopped moving for a moment, the smaller horse lifted his head to point at him and a constant stream of sparks flew from the bigger horse to the smaller horse. In a matter of a few seconds, the two had exchanged sizes, and then went even beyond. Dust and rubble began falling from the ceiling and Dawnheart was starting to panic at the idea of being buried alive. He quickly flipped around and began galloping towards the exit, throwing just one look back at the scene made by the flames. The fiery stallion that had started tiny was now gigantic and surrounded by hundreds of smaller horses. As Dawnheart wondered what was the meaning of this, the ceiling of the cave came crashing down and fell upon him.

It was late in the afternoon when the white horse came back to. He was on the same path where he had found the cave before, except that this time there was no tunnel. He vaguely remembered passing out when the cave collapsed on his head. However, he was feeling so groggy that he concluded that he had taken a nap - even though he didn't remember about trying to do so - and that the whole experience had just been a nightmare. There was no other reasonable explanation. Still, there was something that was odd, he felt exceptionally good, it was as if all of his worries had just disappeared. He looked around to try to remember where he came from when he realized that he had a pretty good view of the farm where he lived. The grassland looked small from where he stood, despite how big it felt when he was down inside the enclosure. It seemed like he had wandered quite further than usual with this stroll and set off to head back before the others would start remarking that he had disappeared.

As soon as Dawnheart saw the hole in the fence behind the barn, his glumness came back to him, stronger than before. He took a deep breath and slipped back inside, trotted to under his favourite tree and laid there, acting as if nothing had happened. He didn't even have time to try to relax; he heard the hoofsteps of the trio of bullies approaching. He wanted to get up and run, but decided against it as every time he fled and hid, it made the things worse for him when the three found him.

Onyx, a giant draft horse with pitch black fur, was very haughty and proud of how gifted he had been with his muscles and his height. The black stallion stood at 7'3 at the withers, he was the tallest of the herd and he was impressively built. His muscles were a sight to behold, it was as if being a draft horse was in his genes, he was able to carry twice his own weight for several miles. Though he was gifted with physical attributes, he wasn't the brightest one; he really lacked in brains and it showed. Anyone who showed even a slight bit of admiration - genuine or fake - would earn his favour.

Prince, a stallion of noble lineage, was a handsome palomino shire horse. He wasn't as tall as Onyx but he was still standing at 7' at the withers, and while he didn't have a lot muscles on his frame, he was a fine and extremely good looking specimen. Being from a noble lineage also guaranteed him to be the top breeder of the herd, his sperm was in high demand from all over the world. All of that, along with his heritage, fed his ego and he acted like he was much better than any other of the horses. He'd only acknowledge anyone who is superior to him in one way or another, though he'd definitely challenge anyone who'd claim themselves to be the most handsome or even just a bit pleasing to the eye.

Flash was smaller than the other two horses, standing at 6'5 at the withers. He had brown fur and was pretty much normal, except that he had something that no other stallion in the herd could ever hope to get. His speed and stamina were unmatched, he could run marathons at record speeds without ever tiring. That wasn't his only strength, his rear legs were so powerful that he could jump over obstacles that were twice as high as what any other horse could jump over. When he was introduced to the pack, Flash was intimidated by the other horses and acted pretty shy; befriending Dawnheart even though the white horse was the runt of the herd. It quickly changed as his confidence grew and he began despising everyone that he deemed useless.

"Hey, shorty." said the draft horse, "why're you in our spot?"

"I... I'm sorry." replied Dawnheart.

"My, my, my, my..." began Prince, "little Dawn, you are ruining our view with your hideous face. Would you be so kind as to disappear?"

"And by that, Dawnfart," added Flash mockingly, "he means you should get the fuck away before we stomp all over you."

Anger swelled in Dawnheart, never before had the three assholes claimed that spot as theirs and he was pretty sure they just wanted to torment him. However he had no intention of confronting these guys and just stood up to leave. For a moment he thought his memory was toying with him, flashbacks of the cave assaulted his mind. Those images were so strong that everything blurred around him. When his eyes were able to focus back on his surroundings, he was surprised to see a large flame hovering inside each of the three bullies' hearts. He looked at them wide eyed for a few moments, though he was quickly brought back to reality as he saw Onyx get closer to him. Dawn turned away, muttering excuses and galloped away.

"Hey, Dawnfart," yelled Flash as Dawnheart was running away "I hope you won't forget about our race. I'm really looking forward to it!"

Once he was sure they couldn't see him anymore, Dawnheart looked back and observed the flames in their hearts. It felt as if those weird fires were calling to him. More flashbacks came to his mind; the images of the flames transferring from the big horses to the small one and more distinctly, images of the small one growing bigger as the flames reached into him. He didn't know what any of this meant but he knew he wanted to understand why he saw the altar, the idol, and the weird fiery show from earlier. He found himself another spot where he could rest and dozed off, dreaming about the cave from earlier.

Dawnheart was having a wonderful dream when he was awakened by the sound of heavy trampling next to him which made the ground tremor. When he opened his eyes, he saw Onyx standing on his rear legs and about to stomp his full weight on the ground. The white horse quickly moved away, fearing for his life. Onyx loudly crashed on the ground next to the smaller horse, rocking the ground with another tremor.

"Oh, is that you, shorty?" said the black horse. "You're so small I didn't see you there!" added Onyx before bursting into laughter.

Dawnheart was greatly annoyed by the disturbance. He got up and looked at Onyx, noticing once more the flames around the draft horse's heart. He stared at it intently, wondering if he could just try to maybe-

"What're you staring at, shorty? Is it my muscles? That must be it, you're envious of me because you'll never have such big and strong muscles and you'll never be able to lift anything that weighs more than a pebble!"

While the beefy stallion was mocking him, Dawnheart focused all of his attention on the flame. He was able to grasp it with the help of his mind and guided a tiny spark out of it to reach into himself. He wasn't sure how it worked, but it worked.

"Hey, shorty. It's rude to ignore people!" groaned Onyx. "You're lucky that I'm in a good mood, so I'll pardon you."

As the giant stallion was busy with his pointless tirade, Dawnheart saw Onyx shrink an inch as soon as the spark left the body of the draft horse. That fragment of energy was still hovering in midair, slowly fluttering toward the white horse. As soon as it reached into him, he felt a burst of energy explode within himself. His whole body instantly burst outwards, making him grow a full inch in height. The rush of power in him felt invigorating, even erotic and luckily for him, Onyx was too busy congratulating himself on his mercifulness to realize that he had been drained of an inch in height.

"Uh... yeah, thanks..." said Dawnheart, struggling to articulate the words because of the intense pleasure running through his mind, "you're the... the greatest indeed..."

Upon hearing that, Onyx puffed his chest up even further and laughed even louder. He was so busy that he didn't even see the white horse slip away.

Dawnheart was amazed by the change that he just went through. While strutting in the enclosure, he stumbled upon Prince.

"My, my, my..." said the noble stallion, "look who it is. Mister uglyface what's-his-name."

Dawnheart bowed to Prince while gritting his teeth. It was the only way for him to avoid a full-on bashing from the noble stallion.

"I don't have time to waste with you today, my time is precious." sneered the palomino horse. "You see, I have an appointment in less than an hour with a gorgeous mare. I have to prepare myself for that and make sure that I'll be up to the task. The struggle of being popular is most definitely not something that a nobody like YOU could understand..."

Being belittled by Prince was something that Dawnheart especially hated. The only thing that the spoiled stallion cared about was looks; he never cared at all about what was beneath appearances. The smaller horse instinctively began using his newfound power to grab a portion of the fire in Prince's heart. As the palomino stallion was already turning away while huffing 'you commoners', he didn't see what was happening to him. A whopping four inches disappeared from the equine noble and were flying in the form of an invisible flame toward Dawnheart. The small horse was curious as to how pleasurable it'd be to gain that much, but that question wasn't left unanswered for long. His whole body was invaded by the pleasurable energy that made him burst in size once again, instantly gaining four inches all at once. The immense bliss that invaded his mind was so overwhelming that his cock exited his sheath and dropped and came to half mast in the blink of an eye. While this felt absolutely amazing to him, the pleasure faded almost instantly afterwards and he was left with a half-hard erection. He took a bit of time to huff and recover from his arousal and then headed to the place where he and Flash would race for the 'daily challenge', which was more an occasion for the race horse to show off rather than a real challenge.

Dawnheart showed up at the usual starting block, which was a fallen tree trunk. Flash was already waiting, trotting in place and getting hyped up for the 'event'.

"Hey, Dawn, how about we raise the stakes?" suggested Flash, "Winner gets to fuck the loser! And if you don't accept, you're a pussy!"

"I don't fucking care anymore, Flash," said Dawnheart. It was like this every time Flash challenged him. "let's just get started..."

"Alright! The crowd is cheering, the race horses are getting ready! On the first door, Flash, the star of the stadium, undefeated yet, will he finally fall today? Listen to those cheers as the incredible stallion just appeared, the crowd is going wild!" said the brown stallion to hype the event, "his opponent is Dawnfart, a newcomer in the stadium that has never performed well, will he finally be able to take back the first place? The race is three laps on the standard obstacle course!"

Dawnheart sighed. Even though he knew he'd lose, he got ready to gallop. An idea sparkled in his mind however; as Flash was getting in place, the white horse focused on his opponent's flame. He took a tiny bit of it, stealing just an inch at first, and getting ready for more. But all of a sudden, Flash gave the go and the race was on. In a matter of a few seconds the race stallion was almost out of sight, galloping through the enclosure and following the usual race tracks. Dawnheart began galloping too, realizing that his speed was much greater than it ever was before. He slalomed around trees, jumped over the water dispenser, running over the track as if his life depended on it. He heard galloping from behind him and saw Flash about to lap him. Dawnheart knew what the other horse was up to, but he wouldn't let him have his way, he prepared himself.

The brown horse slowed down to the same rhythm as Dawnheart just to taunt his opponent "you call that running? This is the pace at which I'm resting! You're so slow it's almost boring!" he said before speeding off again.

Dawnheart smirked as he looked at the sizeable flame that he had gathered and infused it into himself. He grew two more inches and his whole body felt as if it would explode with energy. It gave him a noticeable boost in his galloping speed. He accelerated even more to try and get back to Flash. It was unfortunately nowhere near enough. Despite being faster than he ever was before, Dawnheart was still slower than the brown stallion. He was about halfway through the first lap when he heard Flash's hooves right behind him, so he prepared for another drain.

When Flash reached right next to Dawnheart to tease him again, the brown horse didn't look as good as the previous lap. That however didn't prevent him from taunting the smaller horse, "Hey, Dawnfart, you see that? Even though I'm having a bad day this time, I can still beat you so easily! It's laughable how useless and powerless you are! See you at the finishing line!"

Dawnheart had once again taken a bigger flame from Flash and sent it through his body. This time, he almost exploded in size, gaining four inches all at once. He fought the powerful urge to stop and get off because he was in the middle of the race. Instead, he accelerated once again thanks to the growth and enhancement of his body. He got faster and faster, galloped and slowly caught up to Flash, who was looking very tired. As soon as he was next to the race horse, he smirked at him before speeding up. The two passed the finishing line with less than one second of difference, though that was still a loss for Dawnheart as he had done only one of the three laps.

"I was even having a bad day!" yelled Flash between huffs, trying to make excuses, "I slowed down because I took pity on you! I swear I'm gonna make you regret passing in front of me next time!"

Seeing the anger in Flash's eyes was delightful to Dawnheart. He knew that the brown horse took great pride in his speed; being bested in that regards must have been extremely painful for the race horse.

"And anyways, I still won, so you owe me your ass."

Dawnheart sighed, he had secretly hoped that Flash would be too shocked to remember about that. But at the same time, it gave him an idea. He turned around, showing his back to Flash and moved his blonde tail out of the way.

Immediately, Flash rose on his hind legs and mounted on top of Dawnheart. He approached his filling sheath to the smaller horse's butt and began rocking back and forth as his cock slowly slipped free from its fleshy folds. So many times before Dawnheart had to endure this, but today he'd enjoy it. As soon as he felt the flared head of the stallion's cock against his asshole, he began focusing on taking away size. The flames danced, flowing from Flash's heart into Dawnheart's body, filling him with intense pleasure and satisfaction. Unlike with the race, he wanted to go slowly and enjoy the theft as much as he could, he wanted to make Flash regret his misdeeds. Usually, he'd be gritting his teeth from shame and anger by the time the sixth inch of the race horse's cock invaded his behind. This time, though, he was enjoying it because of how pleasurable the drain was. His own cock was slowly hardening, exiting his sheath and flopping down towards the ground. He began working on his power to slowly attract the energy flames into himself, taking spark after spark. Every one of the little fragments he took made him grow bigger, stronger, faster and more potent. They were happening in little bursts of size; first his muzzle grew a tiny bit, then the rest of his head. Then it was his front legs that gained an inch, followed by his hind legs. His butt swelled next, then waist, chest and neck. Flash was completely oblivious to the changes, even though he had to put slightly more effort into his thrusts with every time that Dawnheart grew. As the first foot of the race stallion's cock slid in his tailhole, the white horse tried to focus the theft onto Flash's cock. And it worked! He felt the shaft in his ass recede a few inches while his own cock throbbed, gaining a few inches in length and getting harder. He then drained an inch of girth for himself, making his shaft expand in width. It was the first time he enjoyed getting fucked by another horse, even though the fucking wasn't the reason he liked it. Every time his body expanded in size, a huge wave of pleasure invaded his mind. He soon had taken enough size from Flash that he had grown taller than the other horse, he was reaching to five feet and half. In an attempt to not make the race stallion suspicious about the theft, he crouched ever so slightly to compensate for his increase in height. In the meantime, he continued draining more and more. He took an inch in height, stole some leg muscles, took more height. His cock was fully hard at a foot and half, which was already one and half times longer than it was before he started the theft. It was painfully hard and leaking droplets of pre that fell on the grass below them.

Dawnheart decided to accelerate the theft, he couldn't tolerate Flash pounding in his ass any longer. He began draining size faster from the now smaller stallion, making himself burst bigger and stronger with every second. His left ball grew to the size of an orange, his dick then burst another half foot in length, his right ball caught up with the other and passed it as it grew to the size of a grapefruit, his cock grew in girth as he took away one more inch in width from Flash. Every single one of these small bursts were so highly pleasurable to him that his shaft was shooting strings of pre with more strength as it grew, and with an increasing output as his balls expanded. He could feel that Flash was close to orgasm and that would be when he'd hit the hardest with the theft. As soon as the race horse began neighing, seed started shooting from the cock, reaching deep in Dawnheart's ass. The white horse sped up his draining of size, not even caring about the consequences should Flash realize what was going on. His whole body was hit by a shockwave of pleasure as he drained everything he could from the other stallion. He started with his bully's cock, taking a whole foot in length and the last two inches that were of girth that he had. His own cock surged forward to three foot long and exploded in width to eight inches wide, and thanks to the overwhelming pleasure, he was brought to orgasm. His shaft grew harder and its flare expanded as it began shooting seed with an impressive strength and output, the jets of the sticky fluid flew way past his front legs and landed a couple feet in front of him. Even though it was difficult to focus on stealing size through the intense pleasure from the orgasm, he continued draining more from the smaller stallion. Dawnheart's shoulders grew, his pectoral strengthened and heaved forward, his belly expanded with size and finally, his butt exploded in size, pushing the race stallion backwards and in a matter of a few instants, he had reached to 7' at the withers. It was at this moment that Flash realized that something was wrong. He was panicking as his tiny shaft was spurting rather large shots of cum. Dawnheart looked back over his shoulder and grinned at the 4' tall dwarf horse that Flash had become. He then used his power once more to aggressively drain from his ex-bully's balls. His left nut expanded all of a sudden in size, reaching to the same width as his right ball, and then the two swelled in a massive burst, reaching to cantaloupe-sized and dropped much lower between his rear legs. This last part of the theft made Dawnheart's orgasm feel that much more intense, his output increased threefold and the jets of cum were fired twice as far away as they were a few moments ago, while Flash' output was reduced to mere drops spurting weakly from his tiny one inch dick.

"Hey!" cried Flash in a voice that was high pitched, "Dawnfart, what did-"

"My name is Dawnheart, you useless deadweight!" interrupted Dawnheart in a sharp voice, making sure to use Flash's own insults.

"Wh-what did you do, Dawnheart, tell me!"

"All that size didn't fit on you, Crash, so I just took it for myself."

"My name is Flash, not Cr-"

"Your name is now Crash, you useless waste of space! Didn't you say not too long ago that if you can't run, lift or seduce women, you're a deadweight that shouldn't have been born? Let's see how you run with those tiny legs now, Crash!" replied Dawnheart, insisting heavily on the dwarf horse's new nickname.

"G-give it back!" cried Flash.

"I'm sorry, Crash, I didn't hear what you said."

"P-please, g-give my speed back to me... I'm nothing without that, please, I beg of you!"

Dawnheart grinned widely at Flash before saying "At least you realize that you're useless now, don't you?" he then turned away and had a wicked idea. He briefly looked at the dwarf horse and sneered "I'll show you what speed really is, Crash."

The white horse then proceeded to gallop, following the race course from earlier. He was so much faster than before, the wind felt amazing against his face and mane, he felt like he could run for hours like this. He effortlessly jumped over any obstacle, sped up through straight paths, perfectly executed any sharp turns and reached the finishing line in a time that was much faster than Flash's old best time.

He trotted proudly back toward the scrawny four feet tall ex racehorse and looked at him in the eyes. "See, Crash? That's real speed. You should feel honoured that a winner like me is making a show for a loser like you. I'd be willing to train you, but only in the form of races every other day. Oh, and let's bet stuff to raise the stakes, just like the good old times, right? And if you don't want to do that, you're just a... boring pussy, was it?"

Dawnheart didn't even wait for Flash to react, he just turned away and went his way. He could still feel the anger-filled glare of the dwarf horse on him as he strutted away proudly and that felt amazing. He was delighted at how his revenge on Flash had turned out.

As he was approaching one of the barns in the enclosure, Dawnheart overheard cursing from not too far away. He strolled confidently toward the source of the yelling.

"How could that hoe reject me! I'm the best stallion she could ever have had!"

As he approached, Dawnheart recognized Prince. The palomino horse was fuming; he was stomping his hooves on the ground while throwing curses and swearing.

"I'm not her type?" yelled Prince, "She should have been honoured to get fucked by a stud like me! Bitches like her deserve only the worst of scumbags and idiots! That filthy commoner had the nerve of ignoring how great and noble I am, it's always the nice guys like me that get..." he suddenly stopped as his eyes fell on Dawnheart. "Oh, good day to you, sir. My apologies for losing my temper, I have been on edge ever since I have been rejected by that... pretty lady" he said, contorting his face as he spurted these two last words. "Who might you be? Are you new to the herd?"

Dawnheart was surprised that Prince didn't recognize him, though he had to admit that it was very convenient for him. He just offered a slow nod.

"Not very talkative, are you? It does not really matter, I do not mind that. My name is Prince, I come from a long lineage of beauty. People say I am the finest and most refined stallion in the whole family. I pride myself in my amazing look and in my humility."

Dawnheart wanted to laugh at the palomino stallion for his stupidity, but stood there in silence, staring at Prince.

"And here I was," began Prince dramatically, "giving you a chance to talk with someone as great as me, and you are giving me the cold shoulder. Not even a single compliment on how good looking I am. Your company is unpleasant, you remind me of an annoying plebeian that I despise and I find that upsetting."

The palomino horse turned away and headed inside an old wooden building. It was a place that the stallions used whenever there was no mare in heat available to tend to their needs. There were individual stations that could act as a substitute for a partner. Dawnheart was well acquainted with this place as there was no mare that had ever wanted to mate with him, they all wanted the bigger and stronger stallions. In that barn-like building, the breeding stations were of very varying sizes and shapes; the most used were the newer ones that were shaped like the back and behind of a mare without a tail. Dawnheart looked at the building from the outside and headed in, finding Prince mounting one of the medium-sized stations and grumbling something about 'blue balls'. The white horse stepped inside and looked at all the section containing the two small-size stations. Up until two hours ago he'd have needed one of those, but now that he had grown a lot thanks to the drain of Flash's height, he could easily handle one of the medium-sized ones now. He approached the row of stations and picked the one that was right next to Prince. The palomino stallion was so busy grumbling about the mare that had rejected him earlier to notice that Dawnheart had risen on his hind legs to mount the station next to his.

Dawnheart's cock began rising out of its sheath, dangling down toward the ground at first, but the more blood was pumped into it, the more it rose up. He already had a foot of it out when he began provoking Prince: "That mare would have had an awful time if you had fucked her like this."

Prince snarled as he slowly turned his head towards Dawnheart "I bet I get more pussy in one week than you'll ever get in your whole life, little Dawn, I don't need you to tell me how-" but he interrupted himself as soon as his eyes fell upon the white horse next to him. He looked in complete disbelief. "You look and sound like Dawn, but bigger and manlier... who the hell are you?"

"I'm the guy that will take your place as the most prized sperm donor of this farm, Prince." taunted Dawnheart "Let me show you how you breed a mare!"

To prove his point to the haughty noble, Dawnheart began pushing his cock into the hole of the breeding station. It felt so tight around his fat cock that it was extremely pleasurable. He shoved two feet at once and his arousal grew, making his cock lengthen as it continued hardening. Prince, who did not like the provocation, began humping faster in his own station, thrusting and pulling out all three feet and half of his cock inside. Immediately after that, Dawnheart began working his newfound power, focusing it on the other stallion. The raging fire that was hidden in Prince's heart looked enticing to the white horse. He'd take great pleasure draining it all while mocking the haughty stallion. Dawnheart started slowly, though he immediately took something that would hurt Prince deeply. His shaft suddenly burst forward half a foot, and a few seconds afterwards, it swelled in girth a whole inch. The increased tightness around his tool felt amazing, especially since that instantaneous growth made his cock reach full hardness, all four feet were buried in the breeding station. He turned his head towards Prince and grinned wide as the equine noble was looking confused.

"What just happened?" said Prince, panicking "Did you feel that? What's going on?"

"Oh yes, Prince, I did." replied Dawnheart, suppressing a moan "And it's going to happen again! And again!"

"What? What do you mean?"

Dawnheart began draining overall size from Prince. His legs lengthened a couple inches, thickened slightly and his hooves expanded. This whole growth was incredibly erotic to him, the wave of power travelled through his body, starting from his butt, then belly and back, then pectorals, followed by his neck and finally, his head. He had already taken away half a foot in height form the noble horse.

"What the fuck is going on!" cried Prince, "Are you doing this? Fuck it all, I'm out of here!"

"Stop right here!" ordered Dawnheart as the palomino horse tried getting down from his breeding station. He then continued "if you leave now, I'll take everything from you. You hear me? Everything. I might feel generous enough to not drain you completely if you stay and witness my ascension to a top class breeder."

"Wh-what do you mean? So you're the one doing this?"

"Do you want a proof? I can give you one." sneered Dawnheart, who used his power to take away two inches in width away from Prince's balls to add them to his own, moaning through the growth.

"Fuck! No! Stop it! I believe you now! I'll stay! Please, don't take everything. I'll..."

"Just shut up. You should go back to enjoy yourself while you still can use one of those stations, Prince. Or you could just enjoy looking at my growth."

After that, Prince went back to his station, though he didn't have the heart for this. Dawnheart could almost feel the resentment and resignation from the horse as he faced his fate. It make him smirk and the more he looked at Prince, the more he wanted to make him pay. He'd take not only size, but also everything that made the palomino stallion proud of himself. He began draining once again, taking small fragment after small fragment of energy away from the horse, making himself grow. He coordinated the theft of cock length with one of his thrusts to make it feel more intense, his shaft burst another half foot in length, piercing the inner reservoir of the breeding station because of the strength of the growth and thrust. At that point, his shaft was reaching to four and half feet in length and nine inches in girth. He continued with that scheme of theft, taking an inch with every one of his thrusts. The look on Prince's face was priceless, the palomino horse who was usually so proud and haughty was now cowering and almost crying as his maleness and virility were stripped away from him. While continuing to hump into the device, Dawnheart paused his theft of cock length to start with another kind of drain. His shoulders burst with strength and muscle mass, then it was his neck's turn. It continued with his face and his snout. His front legs then beefed up and lengthened, making it easier to grip on the breeding station for a brief moment. His butt was forced up as his rear legs lengthened and strengthened, so much so that he had to crouch slightly to be able to continue the shoving of his massive cock down in the device's tight hole. Satisfied with his height for now, Dawnheart decided to hit somewhere else where it'd hurt. It wasn't size, but it was still one of Prince's best feature, his mane and tail. As the flame of energy left Prince's body, the pretty and long mane of the equine noble withered and got rougher, and as soon as this fragment of energy reached into Dawnheart, his hair lengthened, softened and took on a prettier blonde colour. His tail went through the same treatment, changing from rough, messy and short to beautiful blonde tail.

When Dawnheart looked at Prince after that drain, the palomino horse had lowered his head and closed his eyes in defeat, and he had stopped moving his hips back and forth. The proud and haughty stallion was but a shadow of his former self, while Dawnheart had become much more handsome, much bigger and much sexier. He was however nowhere near done with the noble palomino horse, there was just so much more that he could take and he would help himself to it. Dawnheart resumed the theft, making himself grow in uneven messy spurts, his head expanded, then his hooves, then his butt, then his whole torso. There was no stopping him now, he continued taking fragments of Prince's size to add them all onto himself. As he felt his orgasm closing in, he pulled almost the full length of his shaft out of the sexual device, leaving only his flare inside. He then looked at Prince with a devious grin, and more specifically at what was left of the palomino horse's cock. It was just a tiny bit over two foot long and even though that was still quite large, it was so much smaller than just a few minutes earlier. Dawnheart resumed the theft of cock size, coordinating the drains with the throbs of his cock. Every time it pulsed, an inch on length was added onto his shaft, making it slide back inside the sexual device. After a full foot of theft, Dawnheart pulled his cock once more to show Prince how big it had gotten, it reached to a whopping six foot in length. He then very slowly began pushing it inside once more, very slowly, inch by inch, until it all six feet were buried deep in the breeding station. There was still something that went pretty much untouched yet on the noble horse, so Dawnheart got to it. His own nuts burst two inches in width while dropping slightly lower, then his left one gained three more inches and dangled closer to the ground than the other orb. His right one got back in the race, swelling six inches at once, and finally, the two balls swelled until they both were a foot and half wide. The immense pleasure he got from that was enough to send him to orgasm and his cock began firing torrents of cum. Because the internal reservoir of the breeding station had been pierced earlier, seed began invading the whole device, which started leaking some of the white liquid at the seams. Some cum even backflowed toward the hole in the back and began spilling down on Dawnheart's balls and on the ground. The pleasure from this orgasm was so intense that he almost forgot about Prince, but he snapped back at it. All of a sudden his cock expanded a whole foot in length and half a foot in girth and burst out of the device, seams tore apart all around the gigantic shaft, which began pumping seed anew, coating every part of the wall in front of him with the sticky fluid. With the device completely destroyed, Dawnheart turned toward the station where Prince was moping and showered the small horse with his seed. Wave after wave splattered all over the breeding mount and over the white horse, covering everything with the thick fluid. Five minutes after it began, his orgasm finally started weakening; the aftermath was dumbfounding, a good portion of the wall was covered with cum and there were two horse-like masses of seed standing there. One was moving weakly and the other was completely still. Prince shook his head to get rid of some of the seed and dragged his hooves to exit the gigantic puddle of cum.

"Can... can I go, now?" mumbled the white horse weakly.

"Of course you can, little Prince. See? You stayed, so I didn't take everything. I left you one inch, that should be plenty enough for you to use the small stations, right?"

Prince nodded in shame and started walking, leaving a trail of cum behind him as the sticky fluid was slowly dripping down from all over his body. Dawnheart was delighted by the spectacle of the bedraggled four foot tall palomino horse dragging his hooves away while sobbing, how many times had he dreamt of doing just that and humiliate all of his bullies. Now that he had this amazing power, he was finally able to take revenge upon all of them. He was as merciless as they used to be with him and he'd enjoy tormenting them as a way to make them pay for all of the pain and hatred he had felt throughout his time in this herd.

Dawn knew what he wanted to do next, there was still another bully to get back to. There was a place in the enclosure where boulders were lying after a landslide that happened many years ago. It was Onyx's favourite spot as he could work out by pulling or pushing the huge rocks. The black stallion had improvised a harness to pull the rocks and show his strength. The draft horse had made a challenge for himself. Every day, he'd drag the boulders over distances as long as he could and eventually, he'd try to move the giant boulder that was in the middle of the area. For years he had trained to do it, and yet he never was able to make it move an inch. Just as Dawnheart had expected, the black draft horse was working out by moving the large rocks around. He knew the guy was a musclehead, so he quickly devised a plan to get his revenge on him. The first thing that Dawnheart realized upon getting closer is that the draft horse now looked small when compared to him. Onyx was just a bit taller than seven feet tall and Dawnheart was nine feet tall at the withers. He absolutely loved how he could now look down at them and how they were the ones that needed to look up at him.

"Hey, Onyx!" said Dawnheart, booming with confidence.

The draft horse replied without even looking at Dawnheart, he was too focused on his exercise "What's up?"

"Still stuck trying to move that giant boulder?" sneered the white horse. He knew that belittling his strength was one of the things that irritated Onyx the most.

"Who are you kidding? I can now move it an inch a day!"

That threw Dawnheart off. He wasn't expecting the draft horse to have actually made it, that boulder was absolutely massive and had to be incredibly heavy. He however quickly found another way to mock Onyx "Wait, only one inch? That's disappointing!"

"I'd love to see you lift that much weight, you shorty!" shouted Onyx, who was done with dragging this particular rock. He looked around to find Dawnheart and once he saw him, his mouth fell agape. "Shorty? That really you? What happened?"

"It doesn't matter, Onyx. All that matters is that I'm now stronger than you are."

"Don't make me laugh, shorty. Takes tons of effort to become strong enough to drag these rocks."

"How about we make a bet, then?" suggested Dawnheart

"Whatcha going on about?"

"If I can pull this rock six inches, I win. If I can't, you win."

"What's in there for the winner?"

"Winner can do whatever he wants to the loser."

Onyx took a moment to answer. "I'm in."

Without even waiting, Dawnheart went to the rock, grabbed the makeshift harness with his mouth and placed it against his chest. He began pushing in order to drag the rock behind himself. While he definitely overestimated himself, he had a weapon to win this bet: his new power. Draining the two other horses had given him powerful legs, more muscles than he could have hoped for and he was now nine feet tall, there was no way he couldn't do it. And if push came to shove, he could always 'borrow' some muscle mass from Onyx. He focused really hard into the matter, trying at first to use his own strength and digging his hooves into the earth to gain a better grip on the ground. He pulled and pulled, using his whole body to try and drag that boulder behind him.

It was hopeless for him, he wasn't strong enough yet to do it. He thus focused on Onyx and began draining a bit of muscle here and there. His pectorals heaved forward as they grew in strength, then his calves bulged with power while expanding, his whole back and torso exploded with power as he took away the draft horse's muscles. Every time he took a bit, he took a few deep breaths before digging his hooves in the earth to try pulling the rock. As he was losing hope, he felt a rumble from behind himself, a rumble that gave him the boost in confidence that he needed. He stole a tiny bit more muscle to be able to drag this rock, the effort was tremendous but he eventually did it. It moved an inch, and then another, and then another. And then, with what little momentum he had managed to build up, he was able to make the rock slide against the grass for the rest of the needed distance. As soon as he heard Onyx's "no fucking way..." Dawnheart let go of the harness and the rock and went next to the draft horse.

"I win."

"No fucking way... you... you did it..."

"Piece of cake!" lied Dawnheart, huffing loudly because of the exhaustion from pulling that weight.

"I've trained my whole life... and you just... on your first try..."

"I did, yeah. Now, remember our bet?"

"I do..."

"Don't try to find a way out of it, there's-"

"A bet is a bet," sighed Onyx, "you won fair and square, I lost, I ain't tryin' to dodge the penalty."

Dawnheart almost let out a chuckle when he heard 'fair'. Onyx wasn't one to break his promises, no matter the circumstances.

"So what's it gonna be?" asked the black horse.

"You already know what it's gonna be, Onyx," replied the white horse, "suck my dick."

"Figured as much..." sighed the draft horse.

Onyx approached Dawnheart, stood on his side and lowered his neck to bring his muzzle to the white horse's groin. The tip of the cock was already out of the sheath and more was spilling out with every second. The draft horse opened his mouth and licked the shaft, which was hardening faster as Dawnheart's arousal was growing. Even though he wasn't hard at all yet, the girth of that tool was already immense, it was just shy of a foot and half wide. As the first half was completely out of his sheath, Dawnheart got impatient. He used his power to drain a tiny bit of cock length. His shaft shot forward with a large throb that made it lengthen half a foot from the theft, plus a whole foot from the instant-erection effect from the growth. He had already been big before this one drain but now he was massive, his cock was still far from being fully hard and yet it already reached to five feet of glorious horsecock, with his medial ring about four feet from the tip, meaning that there was still plenty more to come. While all this already felt very pleasurable to Dawnheart, he wanted more than just the shy licks that Onyx was giving him at the moment.

"Hey, Onyx, when are you planning to get serious? You've seen how big it is, your tongue is definitely not enough. And besides, I told you to suck it, not to nuzzle against it."

The black horse grumbled in annoyance. He however took a few steps back so that his snout was in front of the fat flare of Dawnheart's cock and opened his mouth. The sheer girth of the white horse's shaft forced Onyx to stretch his maw extremely wide for it to fit inside him. As soon as the flare slid under his next victim's lips, Dawnheart got on his front legs and turned so he'd be facing the black stallion and landed heavily on the shoulders of the draft horse. He used his front legs to encircle the other in grip as tight as he could. He then thrust his hips, shoving a few inches of his cock inside Onyx before he stepped closer to the black stallion. He repeated his movement, forcing sometimes as much as half a foot of his enormous shaft inside the draft horse. The tightness of Onyx's mouth and throat was very pleasurable to him and he knew it would get even better if he drained more so he took half a foot in height from his victim, making the already tight mouth around his cock become even tighter. He paused the insertion as he was halfway through to start humping into Onyx, bringing himself intense pleasure. He leaned to the side to take a look at the draft horse's balls and licked his lips before he took half of their size in one go, making his own cum factories swell half a foot in girth, bringing them to two feet each. His massive orbs dropped lower while sloshing audibly with all of the seed that they were containing and producing. As he was going to reach his fully hard state very soon, Dawnheart resumed humping inside Onyx's mouth. He shoved a foot inside, then stepped closer, then stole a good amount of cock length, then pulled back, then stole a bit in girth, then forced one more foot inside before once again draining some more length. He absolutely loved the way he was toying with Onyx and using his size to gain size in small but incredibly pleasurable bursts. He decided he'd take another foot in size, making his body grow in both size and muscle mass, starting from his back hooves, going through his legs, making his butt swell, then his lower body expand followed by his chest puffing up with strength, then his neck and front legs at the same time and finally, his head. At that point, he became even more relentless with his assault on Onyx's mouth. He shoved a foot, stole almost half a foot in girth, making the black stallion's skull and neck bulge as the width of his cock was becoming larger than the draft horse's throat. He then stole a whole foot in length that was buried even deeper in Onyx's body before he shoved the last foot of his cock inside.

Dawnheart was humping weakly inside Onyx, the draft horse's body looked comically bulged because of the three foot wide and ten feet long cock that was protruding from his belly. The difference in their sizes had become much bigger than when Dawnheart had challenged Onyx thanks to how much he had stolen from the draft horse. He was twice as tall as him, standing at eleven feet at the withers. He was almost reaching another orgasm and he knew he wouldn't need much to achieve it, though he knew exactly what would be enough to bring him to it. With one last drain, he took almost everything that Onyx had to give: one last foot in height, one last foot in cock length, half a foot of width and finally a whole foot in diameter from the balls. It left Onyx with less than an inch in cock length and with an oversized ballsack where his balls weren't even visible. The gigantic burst of size that resulted from that drain brought him so much pleasure that he came. His three foot wide balls began unleashing their contents as the head of his cock flared and began spewing gallon after gallon of the white fluid. In just the first two blasts of cum, Onyx's belly swelled until it reached halfway down to the ground, sloshing with the enormous amount of cum inside. The input of white fluid was so great that some of it began escaping from the black horse's asshole and leaking down on the ground. Wave after wave of seed crashed in Onyx's belly, and after the tenth shot was fired, the draft horse was forced off the ground because his belly had reached down to the earth and was pushing him upward. The pleasure going through Dawnheart's mind was so intense that he didn't even realize that the cum balloon that Onyx had become was swelling so much that his front was being pushed slightly upwards.

Dawnheart's orgasm had weakened enough so that his output of cum inside Onyx's belly wasn't enough to keep up with the tailhole leak of the black horse. He slowly began walking backwards out of the wobbly cum balloon, while trying not to trip and fall, to pull his cock out of the smaller stallion. He took foot after foot of his glorious - and drenched in cum - shaft out, and when the medial ring on his cock slid out of Onyx's mouth with an audible pop, a large deluge of cum began. After looking at the aftermath of his revenge with great satisfaction for a couple minutes, the white horse began looking at himself to see how much he had changed. Dawnheart was mesmerized by the immense size of his body, by the impressively large muscles he sported now, by his enormously long and thick cock and by the giant balls that were already sloshing as they were overproducing more cum. He had become a handsome and virile giant, and no one would ever match him in speed, in strength, in breeding abilities or in anything else. Dawnheart was going to be at the top and if someone ever dared to mock him again, that guy would pay the price just like Flash, Prince and Onyx just did. He looked one last time at the black stallion, or rather, the cum balloon that used to be a draft horse and sneered. He had no use for that dwarf horse anymore.

Dawnheart was walking proudly in the meadow, enjoying the view from his newfound height. His cock was only starting to soften up now, even after the good amount of time since he had had his intense session with Onyx. It was impressive even when flaccid, it almost reached down to the ground. An unpleasant feeling began invading his whole package, making his balls, cock and sheath itch. It made him wonder if it was an aftereffect of the theft, though there was no way he could know for sure.

"Holy fuck! Is that you, Dawn? What happened to you?" said an excited voice from behind him.

The muscular white stallion turned towards the source of the voice, his eyes fell upon Hazelnut, a beige furred horse that stood at 6 feet at the withers. This guy was one of the few horses in the herd that never picked on Dawnheart ever before, he was even one of the very few that actually tried to befriend the small horse. The white stallion was however too preoccupied with the itch that had significantly worsened in the past minute to answer.

"Holy shit, it IS you, Dawn!" yelled Hazelnut, completely in awe before the stallion that was twice as tall and broad as he was.

The smaller horse began walking all around Dawnheart while admiring how muscular and large the white stallion had become. He took a long pause when he was behind the equine titan to take a good look at the giant balls that were dangling between the lower half of Dawnheart's rear legs. A feeling of dizziness invaded the wholly body of the white stallion, who began losing balance and staggered. Dawnheart fell backwards, almost flattening the other horse under his large butt, and landed in a sitting position.

"Dawn? Are you okay? Dawn!"

Dawn let out a loud neigh as the itch in his privates became an unbearable heat that moved towards the depths of his sheath. It felt as if it was growing and getting fuller with every second that passed, and the more it went on, the more the intense heat was transformed into waves of pleasure that rocked through his body. He shivered at the intensity of the feeling and began huffing loudly as his cock began hardening once again. It became stiffer as blood was being pumped into it, it enlarged and lengthened progressively under the eyes of Hazelnut, who was in complete disbelief at the show. The dick began rising upward, pointing at the smaller horse's head. It slowly moved towards the left as Dawnheart's sheath began filling with a large bulge that travelled towards the exit of the sheath. A second flared cockhead began poking out of the sheath and it quickly expanded in size and length, pushing the first shaft to the side. It engorged with blood, growing harder with every second, at a rate faster than the original cock as if it tried to match its size. Hazelnut's eyes opened even wider and his jaw dropped. Dawnheart's new shaft pulsed, gaining a couple of inches with each throb, sometimes growing as little as an inch and some other times bursting half a foot. It quickly grew to half the size of the original and continued swelling, adding more girth and length with every second. Dawnheart huffed loudly because of the intensity of the arousal that this new growth induced in him. He could feel an orgasm rapidly approaching as his second cock was reaching up to the size of the first. As soon as the two shafts were the same length and girth, a surge of energy reached into him, making both of these giant shafts burst with one more foot in length and half a foot in width. The two massive fleshy spires both began leaking copious amounts of precum.

"Ho. Ly. Fuck." said Hazelnut. "Dawn. You know how I said you were too small for my tastes? Well you're not anymore." he then turned his back to the white stallion and lifted his tail away, revealing his well-used hole, "Fuck me. Please?"

Dawnheart didn't have to be told twice, he stood up. Both his shafts were so long that they reached slightly past his front legs and they were so thick that they took up all of the space between his front legs. He stepped closer to Hazelnut and prodded his gigantic left shaft against the hole of the smaller horse. The cock was so thick that it was almost as wide as Hazelnut was, though neither of them cared; they both wanted it. Because Dawnheart was twice as tall as the brown stallion, he didn't even need to mount on Hazelnut's back to fuck him. He just pushed forward while the smaller horse braced himself. The flare of the shaft was so massive that the two had to put in some serious effort to make it slide in. As soon as the smaller stallion's asshole was split open wide to let the flare slip in, all of the rest was easier to push in. Foot after foot of shaft was pushed inside the brown horse, making his body bulge from the sheer size of that fleshy spire. The amount of pre that was shot from Dawnheart's dick was immense, he had been on edge of orgasm ever since his second shaft had appeared and grown. Because of the angle of the insertion, the giant shaft in Hazelnut's body was slowly bulging his stomach, forming a large protrusion in his underbelly skin. The more Dawnheart pushed his cock inside, the more that protrusion swelled, reaching to pass between Hazelnut's front legs. The smaller horse's legs were forced apart as the huge bulge of the shaft in him was growing to be massive. Hazelnut's field of view was obstructed by Dawnheart's second shaft, he found himself instinctively turning his head toward it to start licking at the pulsing flesh. The whole situation of being pierced by a giant shaft and by having another titanic shaft right next to him oddly exciting and that, plus the way his prostate was being smashed by the giant dick in him, brought him to orgasm.

Dawnheart was getting ever closer to his orgasm, but there was something he wanted to do before erupting. He pulled backwards, triggering Hazelnut's protests, taking almost all of his shaft outside of the smaller horse. When there was nothing left but his flare inside, he used his left front leg to bring his second shaft towards the brown stallion's asshole. By some sort of miracle, Hazelnut's tailhole stretched open wider and wider around to accept the flare of the second massive dick that was pushing against his hole. Square foot after square foot of that gigantic cockhead began slipping inside the smaller horse, bulging Hazelnut's whole abdomen with the two gigantic flares that invaded his behind. As soon as the second cockhead was fully in, Dawnheart pushed a full foot inside; both of the dicks were forming huge bulges and the pleasure that the two stallions gained from that was immense. Dawnheart began pushing his cocks deeper, they were fighting for space inside the all-too-small brown horse. Eventually, the two shafts began bulging Hazelnut's belly, each forming a gigantic and obscene protrusion in his stretched body. The two bulges were growing bigger with each second as Dawnheart continued pushing his two shafts inside. They were leaking gallons of pre, which already began filling the smaller horse's belly. As soon as the white stallion was inside Hazelnut up until his medial ring, the protrusion in Hazelnut's belly began reaching past the brown horse's front legs. The outlines of his shafts were stretching the smaller horse's skin so much that every time a giant glob of pre exited one of the slits, it was easy to see the squishy bulge made by the liquid. The more the giant cocks were pushed in, the bigger those rushes of pre were becoming.

Dawnheart pushed forward with a lot more strength so that the medial rings of his cocks could slide through the smaller horse's ass. Hazelnut's anal ring spread even more around the two gigantic shafts and eventally, they slid inside, making the brown horse moan in ecstasy. The white stallion continued pushing his cocks inside his fucktoy, soon reaching to the point where he was fully hilted inside the smaller horse. The shafts throbbed more powerfully and with each throb, a giant amount of pre was forced into the brown stallion. He pulled out and pushed in a couple times to bring himself ever closer to orgasm until finally he reached his release. He neighed loudly with his deep voice and his two shafts began pumping waves after waves of cum inside Hazelnut. The first few shots protruded massively from the small horse's belly, making it look like his skin was elastic. His belly filled quite fast thanks to the huge waves of cum that were flowing in him. His throat was quickly invaded by a gigantic flow of cum that he desperately tried to keep in by closing his mouth, but he was already so stretched that the cum had nowhere else to go. Massive amounts of the sticky fluid began leaking from the small gap between Dawnheart's twin cocks and from Hazelnut's mouth. Despite that continuous spill, the flow inside of the brown horse was still greater than the flow outside and thus, his belly continued expanding. In less than a minute, Hazelnut had already been as inflated as Onyx was earlier, and yet Dawnheart's orgasm was only beginning. The smaller horse had become so full of cum that his legs were forced on his sides, pushed by his ballooning belly. He was also slowly being lifted off the ground until he was resting solely on his own overinflated body. Dawnheart's twin canons continued shooting wave after wave of seed, making Hazelnut's belly swell to ridiculous sizes and completely coating everything in front of Hazel's mouth and behind his back because of the spills. Even Dawnheart was lifted off the ground by the inflating horse beneath him.

When finally his orgasm weakened, Dawnheart was almost standing on his two hind legs because of how inflated Hazelnut was. At this point, the brown horse was a gigantic balloon that was leaking from two points, showering everything with the white stallion's seed. He was amazed by the amount of seed that his cock had shot, but also amazed that Hazelnut was able to take it all. It was perfect for him, though. That day marked the start of his rule over the herd. He'd rule with an iron grip, he'd make his ex-bullies pay for mocking him, and he'd have some fun with Hazelnut when he felt like it.
