The Herd-Master's Colt

Part 1

For Repanbo

By Draconicon

Shadolm knew that a certain little dragon would summon him again, though he knew not when. What had been a mere possibility at the time of their parting rapidly became a surety due to the information passed on by a unicorn in the dragon's presence. She was quite the gossip when it came to her friends, and as they were...acquaintances of some level, she was more than willing to tell him what happened in the mortal world with his little 'colt.'

Gann, as the young dragon was called - heh, young, compared to the Demon Lord of thousands of years - had been deeply touched by their last encounter. Not by the corruption, as Shadolm had done the proper thing and drained the dragon of all but the slightest bit of it during their last meeting, but by the way that they had interacted. According to the unicorn, the dragon was touched, happy, and horny to be treated like a little colt again.

Shadolm smiled as he reclined on his throne in the back of his great hall, running his fingers along the horse-heads that marked the edge of the throne arms, leaning his head back and rolling it along his shoulders. Yes, it was just a matter of time until the dragon summoned him again.

It happened during a meeting with the rest of his herd in Hell when he felt the summoning words, the tugging spells. They were the same as last time, doubtlessly done in a way to try and pull him up as quickly as possible. Perhaps Gann had not been educated on the lack of protections that he had put on his summoning spells, or how non-specific they were. Or perhaps the dragon didn't care, and just hoped that he, the Herd-Master, would reach out and take it as he had the last time.

Shadolm gestured towards his 'court' of mares and stallions, telling them to wait a moment. He reached out with his power over his realm of Hell, of his place of plains and crystal trees, and snagged the spell. With the power of a Demon Lord, he twisted the unprotected summons and reversed it. No longer was it summoning a demon, but rather, the demon was summoning the dragon.

Gann appeared in a shower of sparks before the Demon Lord, the horse smiling as he shifted his loincloth slightly. The green, pink-speckled dragon blushed as he got to his feet, still wearing the same assless chaps that he had been wearing the last time, and he looked right at the big black stallion on his throne.

"Well...hi," Gann said, blushing. "I didn't think you could -"

"I can do many things, my little colt. But we aren't alone."

The dragon blinked, turning, then turning some more, slowly rotating in place inside of the burnt circle in the floor of the throne room. The summoning spell had had its own little effects when it dragged someone out of their own plane and brought them somewhere else. In fact, Shadolm would bet that was the only thing that was protecting this little mortal from the corruptive influences of the Hell plane.

As Gann finally completed his circuit, the dragon had gone from blushing to flat-out burning in the face. He couldn't look away from the various naked or half-naked horses, the stallions covered by loincloths, the mares barely dressed any more than that. Some of the higher-ranking ones had nothing on, showing off their status with rings around their cocks or with piercings in the chest. Their manes, smoky and fiery all, were other marks of status, with different colored flames meaning different things.

Gann stood with his hands covering his butt, looking down at the ground and clearing his throat a few times.

"Um, I think I might have jumped the gun on this one."

"Perhaps," Shadolm said with a smile and chuckle. "But that does not mean that you will not have some fun."

"You - um, are you going to come up and..."

"No, my little colt."

The dragon shivered at that, and Shadolm chuckled as the little one stroked his face with his cheeks, as if remembering the marks of the reins that had been there last time that they had played together.

"But you will stay here, and we will play. Very soon, as a matter of fact."

"Herd-Master, are you saying that you intend to breed this brat instead of me?"

He looked up at the mare demon, the woman thrusting her chest forward, standing with her hands on her hips. She towered over the mortal by a good foot, and her mane was tossed to the side, flaring with blue light and heat. Her legs were thick with muscle, and her rump more so, looking like a farm-horse that had made good for herself.

Shadolm looked at her with a gentle smile, but nodded.

"Yes, that is exactly what I am saying."

"But we agreed! It has been a hundred years of service, and that means I get a studding from the Herd-Master."

"Then we will put your service on hold until we get to it. My little colt here needs a little bit of education of how things work in a herd," he said, gesturing at the dragon.

It was almost adorable how the little dragon looked like he wanted to melt through the floor and disappear. He probably thought that he was going to get his fun and then get to go right back to sleep, go back to whatever he was doing with his life in the upper world, in the mortal world.

Oh, what a foolish little colt. Then again, they were all foolish until they were trained, thinking that they could take on the world with their wild energy and beautiful dreams. It was a wonderful thing for them to have, and one that needed direction more than it needed breaking, despite what most horse demons thought. He leaned back in his throne, gesturing at the mare to back down.

She did, though not without a snort. As she took her place among the rest of the herd again, Shadolm dismissed them, sending them out of his manor. They left, but as they did, Shadolm did not miss the way that Gann turned and stared, watching as the many muscular horse butts walked by.

When they were alone, Gann finally turned to face him again, and Shadolm chuckled.

"I imagine that you didn't expect to be dragged down to see me, colt."

"Mmmph. Do you have to keep calling me that?"

"Do you want me to stop?"

"I...mmmph...no..."

"Is it such a bad thing, to be reminded what you are? Someone so joyous, so happy, so eager to challenge the world? Testing your boundaries every day, only to find someone that will help you explore them safely?"

"..."

He had succeeded in making the dragon blush, so he counted that as a success. The stallion lifted himself from his throne, and wished himself elsewhere.

In less time than could be measured, he was, standing behind his colt, rubbing the dragon's rump through the chaps. Gann jumped, almost leaping right out of his scales, staring at him.

"How did you...you were right..."

"In Hell, I am master of my domain in ways that none on earth could understand."

"...That's scary. And hot."

"Yes, it is. Shall I show you?"

"...Oh, boy..."

"Lean your head forward for me, boy..."

The little green dragon - little, in comparison, as he was quite the tall horse - leaned forward, his head extended a bit like a pet for strokes. Shadolm reached out, rubbing his hands along the sides of the dragon's face, gently scratching under his chin, along his jawline, and up and along the sides of his head. The dragon moaned softly, shivering, his eyes slowly closing.

As the demon touched him, the power of the realm reached through him, breaking through the protective circle that the summoner stood in. It didn't take long for the corruption that the Demon Lord commanded to take effect, beginning to shift, crack, change the dragon's face.

Fur replaced scales, spreading through his face in a soft red color, the sort of shade that looked like the rust on iron made soft and luscious. He smiled, stroking his thumbs under the dragon's eyes in soft, massaging motions, making sure to spread the flesh under the scales that much better.

He dragged his fingers down, rubbing along Gann's lips, making the teeth push in, sinking further into the gums before becoming flat, proper horse teeth, properly like a colt. He smiled to himself as a snout became a muzzle, as pointed ears lifted and rose out of the scales that were becoming fur. The actual anatomy changed less than one might have expected, as horses and dragons were rather similarly shaped.

Finally, he pulled his hands back, allowing the dragon to gasp in shock, waking from the soft petting that he had been receiving. Gann opened his eyes, blinking, and then the dragon with a horse's head froze. His hands came up, touching his face, and his mouth opened in pure shock.

"How...you..."

"I can do anything I like to a mortal," the demon stallion said with a small chuckle. "Here, I am the Herd-Master, and all that enter my lands will become part of the herd, given enough time. All I did was speed up the process in your face."

"Oh boy...oh boy."

"I can tell that this isn't that disagreeable," Shadolm said, nodding down at the dragon's bulge as he began to walk around the summoner's circle. "After all, you quite enjoyed being my colt the last time that we were together. You actually begged for it, if I recall correctly. It was quite the sight."

"Mmmph. Do you have to keep teasing me so much?"

"I do."

"Whyyyyyyyy?"

"Because a colt is a very high-energy little horse...and you get a lot of energy from teasing."

Gann stomped his foot, and it was a rather cute little moment, something that he hadn't quite expected to be as adorable as it was. He shook his head, focusing on the summoner circle, watching as it started to fade. The corruption of Hell was eating away at it, and soon, Gann would be completely vulnerable. Shadolm wondered if the tempestuous little dragon had even noticed.

Chuckling to himself, he walked around the circle one more time before scuffing it with his heel. Gann gasped, finally looking down, and then gasped again.

"Oh, fuck! Why didn't you tell me that was fading?!"

"I thought you didn't want to be teased, or treated like a colt," he said with a teasing smile.

"Yes, but...but..."

"But you didn't expect to hit your limits so soon?"

Shadolm stretched his hand through the summoner's circle, the magic trying to stop him as it had before, but it was useless. These basic protections were nothing for a powerful demon. To a Demon Lord like him, they might as well not exist. He reached through the shield, touching the dragon's shoulder and giving it a gentle squeeze.

"You are here to learn, my little colt. You are here for fun, but to have fun, you have to do what you're told. Don't you want to do what you're told?"

"Mmmph. Maybe if you're the one telling me."

"Don't worry. That's what it will be. Down here, I will be your Sire."

"...Mmmph. That...that might be a button," the dragon muttered.

"But first, we must complete your transformation."

"Do we have to? I mean. I...I..."

"Trust me. It will be so much more fun as a proper colt..."

The demon horse gently stroked down the dragon's back, his finger tracing a line right down Gann's spine. The young man moaned under his breath, eventually taking a step towards the edge of his protective, fading circle. Shadolm took a step back, giving his new 'colt' some space to make the decision for himself.

After a moment, the young dragon stepped through the barrier, shivering and gasping as soon as the heat of Hell hit him.

"Oh, fuck..."

"Yes, it's quite the experience, isn't it?" Shadolm said with a small chuckle, helping support his guest with one hand on his shoulder. "Just take a moment to breathe. You'll get used to it."

"Mmmph. Yeah, but will - ah...oh..."

He could see what was happening, but he'd known that it was coming. The little dragon's cock was starting to thrust forward, filling up the front of the assless chaps. Hell had a way of making someone want to stay, their bodies filled with the energies of the lower planes, their cocks throbbing, their balls filled to bursting. They would want to stay, to find someone that would make them feel good.

It was a lie for most souls, of course. If you did not have a demon to look after you, then the raw pleasure of the flesh would go from a temptation to a need, and a need that would never be fulfilled. That pent-up energy was then channeled by the demons, pushed to various wars in the other parts of Hell, used by the Crown to push its agenda. Even here, away from the Crown's power, the temptations of Hell were strong.

But here, he could give some relief. Here, he could do what he wanted.

Shadolm reached between his little dragon's legs, patting his balls softly. Gann moaned, leaning forward and grabbing hold of the horse's arms, shivering and grinding his hips forward. The bulge was still throbbing, still pushing the leather chaps forward.

"Nnngh...This...this wasn't like this...before..."

"That's because you were protected before. Your master sent you here to see me, and his magic kept you safe. Now, you have nothing."

"Mmmph...why...why is it so..."

"Hell wants you to stay. Hell wants you to want to stay."

The hot air had the dragon sweating, his scales damp and shiny. The soft, rust-red fur on Gann's face was slowly spreading down his cheeks, running along his neck and down to his shoulders. While some muscles started to appear, they were faint, not the bulging sort that the bigger stallions had. Shadolm had expected that; Gann was not a big man, nor was he the sort that would sport such large muscles. He was more the sort to hunt down those that had them and make them into his companion for the day.

Further, further the rust-red spread, going across the dragon's shoulders and along his arms. Gann shook, humping his hips forward almost mindlessly, his eyes closed tightly as the corruption spread through his system.

"It's so...so hot...mmmph...It feels like I'm burning up...but...but in a good way...it's so..."

"Weird?" Shadolm offered.

"Mmmph...yeah..."

"Hold on, little colt. Hell wants you, but you want me."

"Mmph. Yes...you...D-daddy..."

He smiled, leaning in and gently brushing his forehead against the dragon's, giving him the softest of headbutts.

"Call me Daddy, and I'll be your Sire."

"Daddy...Daddy Shadolm..."

The horse-becoming moaned as the transformation sped up, and Shadolm continued the slow ball-rolling on the palm of his hand, gently encouraging the continued shift in Gann's body. There was a slow growth going on, a pleasurable, pleasant show to observe. He could feel the weight in the palm of his hand growing, and knew that the chaps weren't going to last for too much longer.

As Gann's neck started to grow out a bit, getting slightly longer, a mane began to grow in. It was a soft, purple flame out of the back of his neck, something that writhed and grew like smoke and fire. He reached up with his free hand, running his black-furred fingers through it, shaking his head at the way that it was already trying to tangle up.

Just a rambunctious little colt, as ever...

The further the transformation went, the more speed it picked up. Soon, it was down to Gann's hips, his upper body that of a rust-red stallion, the lower half still a green dragon with pink speckles. That was changing, though, his hips growing, flaring, then ripping through the leather chaps as the changes demanded a horse lower body to go with the equine upper half. He was taller, but still sleek, rather than pear-shaped.

As the leather ripped, Gann's cock popped out, showing itself off, giving a little show to the Demon Lord. It throbbed eagerly, wanting attention, and he chuckled, slowly rolling his fingers up from the swelling sac to the throbbing shaft.

"Ah...ah..."

And just like that, Gann started humping his hand like a horny little colt, eager to get off, eager to enjoy his big dick. And quite a large dick it was becoming, as the shaft swelled, stretching forward past what the dragon had. The head throbbed, flattening slowly, becoming more of a proper stallion shaft. Slowly, the already-decent sized shaft lengthened, pushing forward, rising out of a crotch that was becoming more fuzzy, less scaly.

Gann had his tongue hanging out, panting, barely seeming aware of his changes as Hell bestowed on him a proper form. He just hugged Shadolm's arm all the harder as he went through the changes, his eyes closed tightly, his body shaking from head to toe as he was altered, changed, turned into something more befitting this realm of Hell.

The changes went all the way down his legs, strengthening his thighs and calves, but at the same time making them slender. He was a colt, after all, not a stallion, and that meant that there were proportions to be kept. Shadolm squeezed the base of his little colt's cock, and Gann gasped, arching his back.

"Nnnngh..."

"Soon. Soon. Hold it, little colt."

"Mmmph...wanna..."

"Just a moment, now."

He gently stroked the colt's face as the change ran down, spreading to the ankles, running along the dragon's feet. They were slowly changed, too. Not to hooves, as the horses with hooves in his realm were more of the workers, an uplifted feral, but to broad soles, suitable for pounding the earth as one ran, suitable for carrying one long distances.

Still smiling, the Demon Lord gently stroked his fingers up his colt's cock, making Gann shiver the whole time. A little more, then a bit more, and a bit more still, all the way to the tip. His finger stroked along the flared head, teasing the sensitive tip before he flicked his thumb right along the hole on the top.

That was all that it took.

Gann slumped down, his new legs not strong enough to hold him as the pleasure took him. He came and he came, his cock jerking as his new, leathery balls pulled up to empty themselves in his first horse orgasm. Shadolm supported him gently, rubbing his back and whispering softly as the little guy came.

"That's it...let it all out...keep cumming for your Sire..."

The new colt neighed and whinnied under his breath as he kept stomping his new, larger feet, panting as he came. His orgasm lasted for nearly a minute, his cum changing color from white to white with a hint of pink corruption through it. It was nothing harmful, of course, merely a sign that he had been partially converted to a horse demon for the moment. He planned on filtering that out when this was done, but for now, he knew it would only make it more fun for his new colt.

He patted Gann's back one more time, pulling his head back so that they could look at one another. Cupping the colt's face so that they could butt heads gently, he stroked his fingers through the colt's new mane.

"How do you feel?"

"Nnngh...so...different."

"That's alright. It's good to be different."

"I feel stronger...faster..."

"Yes?"

"More...bouncy."

The new colt whinnied softly, pulling his head back, smiling.

"Oh, wow, more bouncy. Is this what horses feel all the time?" he asked, jumping from one foot to another, almost springing from place to place within Shadolm's great hall. "Oh, man, I feel like I could run, and run...and run..."

"Horses can run for a very long time," Shadolm said, shaking his head. "It's part of what we do, after all."

"Mmmph. Can we start running now? I feel like I'm going to explode if I don't burn off some of this energy."

It was like a colt to want to move, he supposed. The new ones always wanted to push their limits, see how it felt to go from place to place, see how their bodies felt. He remembered being a colt a long time ago, remembered how it felt to feel invulnerable.

That was why he had pushed so hard to get where he was. Now, he didn't just feel it. He almost was it.

Chuckling, the Herd-Master flicked himself to the door, opening it slowly. He walked outside, and Gann followed him, the pair of them walking side by side. Shadolm stretched his legs as he walked, his large feet thumping against the earth as he deliberately chose to walk rather than zip about as his powers allowed. His loincloth covered him, barely, and his gold chest plate clicked against his pecs.

The new colt followed, prancing about, almost jumping rather than walking or jogging. Every time that Gann threw himself into the air, it was like the little guy found a new joy in life, like he had found out just how much there was to have fun with.

It was a simple life, as a horse. One ran, one played, one ate, and one rutted. He knew that the cycle would move forward soon. A run, a meal, and then...

Well, then they would have some fun.

As the purple-maned, purple-tailed colt hopped about, Shadolm finished his stretching. He waited for his boy to finish, but eventually had to snort loudly to get his attention. Gann immediately stopped chasing after crimson butterbees and trotted over.

"Yes?" the colt asked.

"I thought you wanted to run."

"Oh, yes. But you can't keep up with me. Not like this," Gann said, grinning as he ran his hands down his legs. "I've never been faster."

"You've never raced me before."

"Think you can keep up, sire?"

"Oh, I know I can."

"Without cheating?"

"Oh, do you think I would cheat? Against you?" he asked, ruffling the colt's purple mane.

"Mmmmph."

Looking out at the horizon, he pointed at one of the stands of crystal trees in the distance. The branches turned upwards in jagged fingers, almost like they were trying to rip the clouds open and make them rain.

"First horse there and back wins."

"What do I win when we're done?" Gann asked.

"Careful, little colt. I like confidence. Arrogance, on the other hand..."

"Okay, what does the winner win?"

"Let's keep that a secret. Besides, I'm sure you love surprises."

"Daddy 'Dolm, why? Why you tease me?"

"Because it's fun."

The stallion smirked, turning his attention to the trees.

"Count us off, Gann."

"Okay, um...Three, two, one, g - HEY!"

Shadolm was already off like a black flash, galloping across the plains. It might have been on two legs, but he still galloped, running like the wind that streaked across the sky at night, faster than the light that chased it down. He heard the colt pick up speed behind him, and smiled as he felt Gann starting to catch up.

At least the colt could make it a race.

If he had not been the Demon Lord of this part of Hell, Shadolm was sure that he would have been exhausted running the colt around. He had forgotten just how much energy a colt actually had, and particularly one that had been changed by the realm. He looked down at the rust-red boy, shaking his head a few times as Gann flopped over into a pile of red hay, half-sinking into it.

"I can't move anymore," the boy said.

"I'm not surprised. You've run for years."

"..." Gann lifted his head, but lift no more than that. "You mean hours, right?"

"Oh, no. I mean years. I knew how long this would take, so I picked a place where time could...stretch, for lack of a better term."

"How long was it back where all my friends are?"

"Oh, perhaps twenty minutes," Shadolm said, shrugging. "For you? Probably about ten years."

"We played for ten years?! We were just...running around, chasing butterflies -"

"Butterbees, actually. Butterflies are quite different down here."

"But for ten years? How?"

"I told you. Colts have a lot of energy."

Gann stared at him, then flopped over, flailing his arms and muttering to himself in incomprehensible grumbles. Shadolm chuckled, shaking his head as he leaned against a bale of hay himself. They'd come for a stop at one of the barns that he had set up at the far end of his particular domain, for those that wanted to enjoy their time as horses in a more traditional sense, to indulge in certain types of play.

From what he remembered of the last time that he and Gann had fun together, he was all but sure that his colt would enjoy what he was planning.

First, however, they needed some sustenance. His connection to his dominion told him of fruit that was grown and picked, and with a thought, it appeared in his hands. He offered an apple to the flopped-out colt, but Gann whimpered.

"Too tired, can't reach."

"Must I feed you?" he teased.

"You wouldn't."

"I would, and will, if you don't sit up."

"Mmmmmmmph!"

Gann tried to reach up, his arms straining at the shoulders, but the rest of his body refused to move. It was just as Shadolm had thought. The colt had pushed himself that little bit too far, and that meant that he was completely exhausted, his body too tired to play, his limbs too tired to do what he wanted.

"It seems that I must take care of you, since you can't take care of yourself," Shadolm said, kneeling down at the colt's side and slowly lifting him up, putting the smaller horse on his lap as he supported his colt by the back of the neck. He held up the apple, a flicker of his power cutting it into slices as he offered one.

"Eat," he said, his voice deep and firm, but gentle.

It didn't take long for Gann to stop squirming and eat the apple like a good little colt. Shadolm smiled, slowly running his fingers along the back of his boy's neck, stroking him from the back of his head down to mid-spine, and then doing it again, and again, and again. The submissive colt moaned, his eyes half-closing as he sucked on the apple slices, munching them quietly before swallowing. He would open his mouth for more, and the cycle would begin again.

When the whole apple was gone, Shadolm pulled the colt against his chest, nuzzling him gently.

"Better?"

"Mmmph. Yeah."

"That's good. You were close to overworking it."

"I wasn't trying to. I was just having so much fun."

"I know. That's why I let you."

"Mmmph. So...What was the bet?"

"Hmmm?"

"We put a bet on that first race. You wanted it to be a surprise. What is it?" Gann asked.

He smiled, shaking his head a few times. That was something he'd have to do tomorrow, considering how tired his little colt was now, but that was something that was going to be a lot of fun.

"Don't worry. You'll enjoy it."

"Come ooooon, tell me."

"Not yet. Soon, but not yet."

Patting the boy a few times, he allowed his colt to rest against his chest until he felt ready to stand up again. Helping the rust-red horse to his feet, he walked him towards the barn. There were some oats in there, as well as a few other treats that would help Gann embrace his new equine body, something that would leave him comfortable and allow him to start resting for tomorrow.

Because he was going to need it.

The Demon Lord smiled to himself, feeling the eyes of various other members of his herd following him as he walked along. It was not common, though not unusual, for him to play with mortals. It was, however, a rarity for him to bring them down to his realm without the other members of the herd getting to know them first. It was considered a courtesy for anything more than a one-night stand.

He knew that he had a little to make up to them. They'd be able to get to know Gann better tomorrow. They'd get to know him very, very well. And considering how much his colt wanted to play around, he knew that Gann would love it, too.

The End

Summary: Gann is summoned to Hell when Shadolm reverses the dragon's summoning spell. He is then given the chance to really become a colt, instead of just play one for the Demon Lord.
