A sequel to Dirty Inflation…

Arctic stood in the throne room of Canterlot Castle, the magic of the two alicorn sisters winding around him. Moment by moment, his body was no longer his own, though the pegasus pony still had his wings, his tail and more – all the parts of him that he was so used to. Even the cutie mark, which was often covered up by something that his mistress deemed appropriate wear for him, stayed the same, though his body did not.

He whimpered, his light coat moving over flesh and bone, though there was no pain, only a sense of weightlessness as Princess Celestia’s magic bound with Luna’s, helping him to stand upright, on two legs, his spine re-aligning itself. Parts were the same but, being changed from a four-legged stance to a comfortable, anthropomorphic body was not something that the pet-pony ever thought that he would get used to.

“Stretch out your wings, Arctic, you know it helps settle the transformation.”

He tried to think of the grandeur, the splendour, of the throne room, to admire the stained-glass windows so that he did not have to think about anything else, even though his heart beat harder and faster. For he could not forget just why it was that he was being set on two hooves instead of four, his forehooves moulding seamlessly into more pliable, dextrous hands, fingers aching oddly. He flexed them, sucking in a breath, his chest lightly muscled, though his sheath and balls were even more obvious in such a position.

Of course, they used their magic a little more to play with him, caressing him, stroking the plump fullness of his sheath as his balls hung down, trembling with the tiniest shifts of weight in his body. His massive prick could not help but slowly, so slowly, slip out, filling his sheath and swelling forth, hardening in a thick length of stallion flesh that, oddly enough, was not all that often used for the virility he possessed. His mistress preferred to turn that against him in most cases, reverse-milking him so that his balls backed up, his body producing more and more seed with nowhere for it to go, or if she took his cum from him, it came without the usual dose of pleasure from him.

Such was the will and the life of being a pony pet. And it was a place that Arctic was only too happy to be, submitting to his mistress and doing all that the others around her willed to. He was there to be hired out and he was the only one who could be entrusted to satisfy the evil desires of the other halves of the princesses, their darker halves with such sordid desires that, so often, they could not be spoken aloud.

They preferred him that way, apparently so, using hands themselves to manipulate and use him, though their magic, to be fair, could have more than easily done the trick too. But that was not for the submissive pegasus to worry about, not when his life and his day was well and truly out of both his hands and his hooves, Princess Luna leading the way down the steps that had appeared beside the throne to the dungeons. Those, of course, were kept locked by magic at all other times. Somepony might have considered Arctic privileged to be able to see such a part of Canterlot and the castle, but the stallion wasn’t sure about that.

“Thank you, Arctic, for being willing to do this once more. As you will see, their desires have…grown.”

He gulped, but Celestia was behind him. They may have been sympathetic to his cause and the reason he was there to please the nightmares of night and day, but there was no real option for him to back out either.

“It keeps them in check,” Celestia added, a deeper note to her voice. “Our magic holds them, but it grows tiring to push them back if they are antsy. And that’s putting it mildly.”

He lowered his head as much as he was comfortable doing while still descending the steps.

“Anything I can do to serve, I will.”

For that was his cause and place in the pony world as their pony pet, owned by Mistress Shy and doing her bidding under due orders at all times. The cell, however, that he was led to, was not quite the same as what he had been used to, the cavern larger and more open, though it had looked more like an expansive, somewhat homely, prison cell before. The bookcases and amenities, for their use, were still there, of course, but it was all one big open space, the roof rising into the stalagmites high above. They glowed with the lingering, resilient magic of the castle and the princesses, but he did not think of that, trembling on two hooves, his cock hard and wanton. For the evil alicorns were there before him and there was no turning back to the comfort and safety of Mistress Shy anymore.

“Well, well, well… Look who has come to visit us, dear sister.”

Arctic could not be sure who Nightmare Moon was speaking to, whether Daybreaker as her “sister” or Princess Luna, though Luna took half a step back, her muzzle wrinkling in distaste. Even after her time on the moon, however, she was too proper and composed to rise to the bait. The entry to the cell was about the height of the grand doors into the throne room, metal bars blocking the way, though a magical signature was required to unlock it as Luna, cautiously, did so.

The door clicked open and he took a deep breath. He could have squealed and run and said that he didn’t want to do it anymore, but, truly, he would have been lying, in some way. His cock throbbed and bounced under the weight of his arousal, pulsing and drooling, for he was not wearing any gear at all, nude from head to hoof, everything that he had on show and available to the nightmares of day and night before him. Daybreaker, with her flaming, dancing mane, licked her lips, the two alicorns already in anthro form, leaving only Celestia and Luna in their more conventional four-legged shapes as the princesses of Equestria.

“Come in, come in,” she drawled, though the flash in her dark eyes begged ill-will. “I’m sure we can, ah…be suitably entertaining for a slut like you, Arctic.”

It was one of the only times that she had ever said his name and the stallion caught his breath, a band tightening around his chest. It was wrong but it was right, coming from her, in that particular tone, a voice that made him want to drop to his knees and worship her, service her, do anything dirty, decrepit thing that either of the evil alicorns would have ever wanted him to do.

Quietly, knowing when their presence was no longer needed, Celestia and Luna retreated, locking Arctic within their expansive cell. It was not much of a cell anymore, to be honest, but he supposed, through a delirious throb of anticipation, that that was the price for housing two of the most wicked beings in all Equestria. And it was him that would satisfy them, soothe their lusts so that, at least for a little while longer, they would be “happy” with being restrained and not turn their attention to more devious means.

That was, after all, what everyone hoped. But maybe the alicorns already had all the power they craved tucked away down in that dungeon, the caves offering them everything without even having to go after it for themselves.

“Look at the slut stallion, he’s already hard. And you don’t even know what we’re going to do to you yet.”

Daybreaker walked around him in a slow circle, taking the stallion in from all angles, although both were still bigger than him in their anthro forms. Arctic was large, even for a stallion, in more ways than one, his cock throbbing, standing out straight before him even if it could not help but pull down lightly under its weight. No matter of blood in the world filling his dick with passion could keep him rigid under such condition, cock drooling thick dollops of pre-cum, a stallion-like whicker on his lips.

“Ohhh, he is randy…” Nightmare Moon licked her lips, showing her fangs as the starry nebula of her mane danced back and forth, catching the eye. “But I can take care of that.”

No more were Princess Celestia and Luna there to protect him, not that they would have done anything anyway. For Arctic knew well and truly what he was getting into as Nightmare Moon lunged for him. A flicker of darkness enveloped her and her power swept through, not even needing her magic as her wings flared, lancing through the air in the blink of an eye. He squealed but didn’t even have a chance to take a step back before his hooves too left the ground.

Airborne, strangely so. Yet the feeling of weightlessness only lasted for a minute as he was turned upside-down, the cell jolting around him, made to know, in no uncertain circumstance, that he was there to please and only to please. The nightmare queen, however, was more powerful still and even a hyperphallic length such as his posed no true trouble to her as she sucked his cock-tip into her mouth.

“Mmmph…”

It took Arctic a moment to realise quite what position he was in, his legs pushing…what was it, over her shoulders? He was upside-down, facing away from her crotch, though he wondered, vaguely how it would have been if he had faced her, his nose pushed into her crotch. Of course, she was too large for him to line up in that manner, which was a shame, even if his heart pounded fiercely. His balls rested on her chest as she kneaded and squeezed them, taking delight in the susceptibility of his body to arousal, cock throbbing despite his predicament, so much cum contained within his foal-makers. Her size worked against him even as she dragged him in against her, cock disappearing inch after gloriously fat and heady inch straight down her throat as it bulged around his size.

“Ohhhh…”

Arctic moaned out loud, as much as his head spun, wings flapping helplessly, though they did not feel large enough in an anthro form to take flight and lift his body from the ground. It was difficult, so very much so, as he grunted and gasped, but pleasure had to come one way or another as Nightmare Moon dug her fingers deliriously into his fat nuts as they spilt down. Upside-down, they bounced on top of her head as she deepthroated his dick, though he could only be glad that they parted to either side of her horn, the heft and weight of them rendering them churning.

Yet there was another alicorn there to take him and he felt the heat of her flames before he knew she was so close to him, dragged back from Nightmare Moon’s crotch and lower abdomen, even though his tongue was already out as if he sought to please her. The alicorn’s arms tightened around his hips, arms hooked around his legs to leave her hands free to grope and squeeze his nuts with too much force, but Daybreaker demanded more. She squatted a little to bring herself to a better height, snarling and grumbling under her breath about Nightmare Moon putting him in an awkward position, though all it took was dragging his head back to an admittedly uncomfortable angle to cram his head between her thighs.

“Get to work, slave!”

That was all they saw him as, all he would ever be to them. Daybreaker settled for lying back on the ground, her shoulders and upper back pressed into the ground and her legs raised, though she did not need to contract her abs to keep her legs off the floor. Oh no, it was much easier for the alicorn to use Arctic’s body as leverage, looping her thick thighs and strong calves around his shoulders and upper body, a hoof digging in here and there – but who really cared about something like that? It meant that she had to push her buttocks up towards him, but his muzzle was far more easily accessible to her like that, Nightmare Moon grudgingly acquiescing and lowering him, just a little, so that the two of them could be pleased at once.

All he knew, all that he had to know, was the sweetness of Daybreaker’s pussy as he dug his tongue fervently into it. Pleasing a mare in such a way was a form of worship, especially to him, something that had his head spinning and swimming, taking him away to a deeper, more passionate state of being. It was sub-space, something that Mistress Shy had taught him about, but he could go into that deeply submissive, subservient state of mind in many ways, his lust rising, curling deep in the pits of his guts.

His balls ached and he did, at that time, experience true pleasure as it swept through him, ecstasy bringing a shrieking whinny to his fluttering nostrils, as muted as his cry was by Daybreaker’s thick thighs. She closed them more fervently around his head, forcing his tongue into place over her clit, even as she gushed and practically painted his muzzle in her juices. Such a flow would not be stopped as he strained and moaned, trying to gulp down every drop, though only a small amount slipped teasingly down his throat as it worked and worked.

“Unff… You’re just like you were before, slave.”

Whether that was a compliment or an insult did not matter to Arctic, not considering all that he could do for them, the devious nature of their inclinations. He didn’t want to be in control, not one bit, not even as Daybreaker released her bladder while his muzzle was still shoved between her thighs. There was nothing clean and fresh or delicate about either of the alicorns, their carnal passion demanding satisfaction at the cost of all else.

One load. As piss splattered and coated his muzzle, he grunted through it all, his nuts churning, spending a load of seed down Nightmare moon’s throat. Barely an inch or two of his dick remained outside her muzzle as she swallowed down everything he had to give, pouring straight down into her grumbling stomach, though there was still plenty more where that came from. It was not enough for her, never enough, though Arctic was too caught up in pounding, mind-numbing ecstasy to wonder just why she was so intent on draining his balls, why his creamy load of stallion cum was what she had gone for first.

But that would come to be known later as Daybreaker ground on his snout, marking him messily with her juices. Her arousal squirting, painting him once again in her essence, yet he parted his lips willingly to take it all, his tongue pushing out over his bottom lip as if he needed to signal his readiness and willingness in some way.

She pressed him deeper, his nose almost seeming to disappear into her folds, her scent enveloping him. There was nothing else left in Arctic’s world, right then and there, but what the alicorns laid forth for him, his moans rising, muted, muffled, and still there. The acrid aroma of piss was a welcome companion in such circumstances as what had had to be the third load of seed shot from his nuts, which were only slightly smaller from having been milked in such quick succession. He was sensitive, too sensitive, and yet there was no escape from sensations crowding in from all sides, assaulting all his senses.

The taste of her cream mixing with piss, a delectable concoction that had him flushing even as he slurped it all up, reeking of them. The aroma clung to him, marking his muzzle, his coat, though there would be nothing more that he would more proudly wear, if given the choice. The feel of being sandwiched between their thickly muscled, dominant bodies, layered over with a feminine nuance of softness that did not hide their power in the slightest. Yes, that was how he liked it, his vision filled with the white of Daybreaker’s legs and marehood, the winking folds tugging against his tongue as he brought her to orgasm after orgasm.

Finally, their moans filling the air, claiming him, dominating him, sent him spiralling deeper into blithering subservience than ever before – or, at least, that was how it felt every time to him. He was their slave, their pet, yet another load of cum pouring forth, the milking ripples of Nightmare Moon’s throat pulsing around him.

There was no denying him as he gave over everything that he was to the alicorns and more.

Daybreaker, however, had a more devious nuance in store for him as Nightmare Moon set herself about draining his balls. Oh, that manner of water sports had been light, a little touch and a taste of the dirtiness that was to come for him, though she did break for a moment to release her bladder again. The slave pony moaned out loud as a hot stream of urine soaked his mane, streaming between his eyes and through his forelock, dirtying his coat in a yellow gleam that would soak in and set him up for all else that he was to do. He drank some, the little whore, though not even Daybreaker considered him to be in his right mind as he strained to press his muzzle to her cunt, letting her piss flow straight down his throat.

“Whore…”

He heard the word, but that was all he wanted to be, even as his head spun. He didn’t know what had happened, not at first, but a dirty smog of her gases rolled forth. Her tail hole puckered and trembled as she let it loose, the sound cutting through the air, blasting him and dousing the slave in rancid essence. He gasped, eyes streaming, but he had to keep pleasing her, another load of cum leaving his nuts, revulsion making him squirm, yet the weakness that swept over him gave light to something else.

Submissiveness… Well, it ran deeper than pleasing mares orally. It ran deeper than staying in bondage for hours, solely to make his mistress happy. And that was just why Arctic was a pony pet, a slave to those that considered him such, a pissy pony, a toilet slut, everything and anything that others wanted to consider him and more. She broke wind again, stealing oxygen from him, the deep musk of the alicorn working its way all too easily into his fur, his mane, clinging to him like a second skin.

“Take it all, you fucking slave pony.”

Nightmare Moon grunted her agreement, though her arms trembled around him, hardly able to hold him for too much longer, even as Daybreaker alternated between dousing him in the smoggy air from her backside, the reek cloying and clawing at his respiratory system, and pissing. It was more difficult to do both things at once with the devious accuracy that she wanted, head thrown back in passion against the ground, tongue hanging out with a wicked grin stretching her lips.

“Yesss…”

Yet the evil alicorn of darkness could not hold him up for much longer without pulling on her magic and, well, she had far better use for that. Arctic hung from her, his legs over her shoulders, like a dead weight as he struggled and gasped, fighting for air that was no longer fresh in the manner that he wanted to claim it. He wheezed as Nightmare Moon dropped him, though they had no concern over his safety or comfort in the way that he might have wanted them to think, all legs and arms sprawled while Daybreaker shoved him off her with a glowing burst of golden magic.

“Being more careful would not hurt, dear.”

She hissed, tongue flickering out, treating Arctic to a touch of her anger, the alicorns facing off against one another. Yet there was, most thankfully, the lure of a stallion cock for them to take, his dick standing up firm and hard, though Nightmare Moon was slower than Daybreaker to claim it, regardless of how sloppy her inner thighs were with her juices. Daybreaker smirked as she impaled herself on that dick, Nightmare Moon’s bloated stomach revealing just how much of Arctic’s cum she had taken down her throat, though she still licked off her lips as if there was a drop more for her to savour.

“Oh, yesss…”

Daybreaker rode him as if he was nothing more than a living sex toy, Nightmare Moon squatting over his face. Arctic squealed breathlessly, though was still too dizzy and faint, the cell feeling as if it was tipping and jolting around him, off-balance and lying there helpless. He couldn’t even get his hands up around Nightmare Moon’s hips and arse to please her more, to rub and caress and worship her in the way that he knew that she adored.

His dick ached, but he didn’t have to think about that, some of his nuts drained but still more loads to cum, his body working overtime to replace what had been lost. Arctic was not such a fool to think that milking him dry, in a pleasurable way, was what they wanted over and over again, however, too canny for that, as much as his gut ached to know what was planned for him. The flaming princess riding his cock threw her head back and moaned out her lust again and again for him, slamming down, resting on her hooves so that she could squat and gain the best leverage to ride his cock. It bulged up into her lower abdomen as she slammed down, yet he was thick enough to please her despite the differences in their heights, the alicorns so much larger than him even then.

He gasped, shocked back to Nightmare Moon as she could not merely content herself with slathering his tongue in her honey, the tartly sweet essence that flowed so freely from her pussy that it was as if there could be no end to it. Again and again, she humped down against his face, taking her orgasm at the same time as squirting her piss in his face, hosing him down, letting the thick stream paint him yellow. Her orgasmic fluids were nowhere near enough to make the piss pony anything other than what he was, a slut and a slave that revelled in the dirtiest of play, the acrid stench of urine clinging to his coat, seeping into his mane. No part of his head and neck remained dry and she laughed mockingly as she crushed her marehood to his lips, forcing him down and pinning him in place so that he had no choice.

No choice but to gulp down her piss, taking it down his throat. He gulped and swallowed so that he would not choke on it, yet Arctic did not even have the energy in him to tell himself that it was to please them, to serve them, that he did not truly enjoy it. It was vile in a way that made him, instinctively, want to squirm away from the sordid nature of it all, and yet he did not, his hands finding her thighs, straining to hold the too powerful alicorn down on him while her piss filled his belly.

“All of it, piss pony… Waste a fucking drop and there’ll be Tartarus and all the monsters down there to pay for it.”

He didn’t know what that meant and neither did he want to, eyes closed, losing himself in the moment. It was better, in a way, to slip away, to forget, Nightmare Moon pissing down his throat, his throat burning with the reek of it, how cloying and thick her urine felt when it was so hot, taken straight from the source. Daybreaker was no better, riding his cock fervently, her mane whipping back and forth, her belly bloated from one load that he had not truly felt in his debasement.

The slave pony’s nuts ached, he couldn’t give anymore… Yet he was forced to. It did not matter to them that every orgasm pained him, that he wanted a different kind of release, only that he was there to please them in every way that they wanted him to. Daybreaker’s belly swelled heavily as if she was pregnant, though he was not present for all of it, blinking as the scene changed before his eyes. One moment he was gulping down piss, his stomach heaving and roiling with the sheer volume in his belly, and the next he was sucking on the fat nub of Nightmare Moon’s clit, bringing her off again and again as if that had been what he’d done the whole time.

Time had no meaning down in the dungeon as they howled, riding him with feral cries that he would never have heard from Mistress Shy. They were raw and, in a way, regal, yet still not in the same way that Celestia and Luna were. There would always be a difference to the evil alicorns, a brokenness to them that came through in their willingness to explore debauchery to an extreme that no one else was. Between all four alicorns, good and evil, indeed, they led the way.

Daybreaker took six loads of cum into her womb, depleting Arctic’s natural production while Nightmare Moon panted before her, tits heaving, the huge mounds of them begging attention. With her womb massively inflated with cum, his cock crammed up as deep inside her as it could possibly go, her orgasm yet again painted his cock with her cream. Her delight slopped forth messily, marking his dick, his thighs, even her inner thighs too, the drooling mess of it something that would not be stopped even as she kept his seed inside her.

Still… It was too clean, too pristine, all in a way that oh so very much was not in keeping with what they had the slave pony there for. To be a slave to them, a piss pony slut, was all well and good but Nightmare Moon took her leave and liberty of him, pressing her tail hole to his lips and forcing it between. There was no denying her as he squirmed and weakly fought, arms falling out against the ground, a blast of rancid air flowing into his mouth. He choked on it, hacking and gagging, but he could do what he liked under her, as far as she was concerned, as he would get the full dose of it whether he wanted it or not.

A toilet slave, nothing more or less to them. Frankly, they could make him be whatever it was that they wanted, whatever they craved, grinding onto him, Daybreaker keeping his loads in her womb while she released her bladder too. Other than his head and neck, perhaps a little of his chest, he had not been duly marked, after all, and a hot and ready stream of piss gushing down around his crotch, staining his sheath, swilling around the base as gravity took it, was just what was needed. Between them, Arctic twitched weakly, feeling as if he was fighting with all his might, overcome with the strange sensation of having wet himself even as his cock and balls screamed for relief.

But he was there and there was no escape as he moaned into Nightmare Moon’s backside, taking the reek of her stench down into his belly. He had to gulp it, though gulping air felt wrong, going down the wrong pipe, grunting and heaving, the strain in his stomach burning through with a sharp pain. The pain should have been grounding but it sent his mind spiralling even more, enveloped in the reek of her, piss coating his fur, soaking into his lower abdomen, the paleness of his coat there, once again, stained with stark, yellow piss.

“He loves it.”

“He’s such a slut.”

“And, oh, what we have in store for you…”

Continued from part one…

He tried to grab a gasp of clean air but there was so much of a thick smog around him that even breathing through his nostrils did not allow him any respite, not even then. It enveloped him in a dizzying haze, Daybreaker riding him and Nightmare Moon grinding down on his muzzle, her dock pressed over his nose so that there was no escape to be had. Her musk swamped him and he swore there was wetness over his neck too, the mare wasting no time where she could abuse him.

Her marehood flexed and twitched as she squirted, piss mixing with her juices, though it was all so erotic to her that to hold back one but not the other would have been outside the realm of possibility for her. She needed it as much as he did and Arctic was merely there to serve every one of her filthy needs, blasting gas over him, the pucker of her anal ring rippling and twitching within his mouth, his stomach bloated and heaving. Her gas could only go one place and that was down his throat as he heaved for filthy breaths, eyes bulging, his belly strained and tight, though the piss sloshing about inside with a mix of mare juices was a little better, just a little. It was hard to think of any one thing as his head spun and spun, his cock throbbing as one last load, for the moment at least, was taken from him, Daybreaker moaning. Her head tipped back as she too released her bladder, yet the noxious fumes from under her tail were not as terrible when released in such a place. Still, she added to the thick, heaving smog, a cloud of it encasing him, wrapping around so that there was no escape, his eyes streaming, whimpering as the bloating strain in his stomach tightened and tightened.

“Now…”

He trembled, his whole body aching. More… Yes, there had to be more, though they did not use their magic straight away to show him what that was. They dragged him, a dead weight, exhausted and forced through everything, wanting to please, as tired as he was. The metal chair seemed to be designed for a pony like him, though the open expanse of the cavern begged the reasoning behind its placement there, shockingly small in the grand tenacity of it. He was strapped in, in his anthro form, his wrists locked to the arms and his fetlocks manacled to the legs. That there was nothing around his waist or hips, well… He didn’t want to think too much about that.

Daybreaker waddled with the weight of his cum in her womb, though she was not content with all that had passed, not yet. His head hung, belly bloated, the strain of holding so much gas inside him making his belly gurgle and churn, giving him the impression that even that was working its way through his intestines even then. Could he release it through his own tail-star? He wasn’t so sure how helpful that would be, not when there was that old scar in there still that would be disturbed, not ready for whatever it was that they surely had in mind with him.

“Toilet slave…”

He shuddered.

“We have a burden to rid ourselves of.”

Oh…

“And you are the vessel.”

They made a show of hauling in the machinery, tanks and pumps, hoses dangling, grunting and heaving as if everything took far more effort than it did. The alicorns, of course, were strong enough to do whatever they pleased down there without exerting themselves physically at all, but it was all a ploy to make him squirm, lips parted even as he panted. Arctic whimpered and shook his head and yet, still, did not say “no”, not out loud, not that he didn’t want it. For his purpose in life was to serve, regardless of the disgust he held in his heart for the filth of it all.

His cock, after all, told a very different story, standing up tall while they surrounded him, the blinking lights and whirring gears catching his attention, ears flicking back and forth. It was too much, too much all at once, his cock sore and needing respite, though he knew, of course, that that was not to come. He never got a rest when he needed it.

The machines hissed and ground and he shrank from them, the beeps most terrifying to him, erratic and startling as he nickered nervously. Yet Nightmare Moon turning her back to him, Daybreaker helpfully pointing his cock more horizontal for her, to grind back onto his length was something that he did not expect. There was a shot of pleasure to be taken alongside the strain as not her marehood but her twitching tail-star pushed back onto him, the alicorn grunting as her wings spread, feeling the thickness of him.

“Ooof… Yes, this is much better than a dull, lifeless toy…”

He moaned. Yes, he was a living toy. Maybe that was why he managed to interest them so, to catch their attention. Yet he could not sweep himself away from the throbbing pulses of pleasure, grinding onto him, the tightness of her hole increasing every time she clenched down, most likely only to hear him whimper. Toying with the toy had always been one of their favourite pastimes when it came to him.

It was…different. His eyes widened and he scraped in ragged breath after breath, the filth of the room still present, near enough toxic gas from their backsides reeking through it all. Her backside was not clean, far from it, clumps of excrement clinging to her passage, though he could not possibly consider it to be accidental. No, anything that came with filth-play, with them, was deliberate, terrifying so.

His cock throbbed, unable to do anything but to take it, his entire length disappearing into her mucky arsehole, right up to the hilt. And she was hardly gentle with him either, the flared tip of his shaft scraping along her filthy walls, the mare humping and grinding, spreading her wings as she released just a little more of the tension inside her.

“Unnff… Yes… Yes!”

She screamed, showing her fangs, horn glowing in a blistering flash of magic, but he did not climax with her, regardless of how much the alicorn tightened around him. Nightmare Moon humped and bucked back onto him as if anal penetration was all that she had wanted and yet he could not relax into the moment, knowing that there was something more to come, something that he could not anticipate, regardless of what they had done to him previously.

Her marehood squirted, coating his hanging nuts with a liberal dose of her fluids, his knees wide enough to allow his balls to sink between them. The slickness of it only added to the mess but her grunt as she stayed, to the hilt, on his length heralding her piss splattering forth again in a rancid hiss. His pale nuts were sullied well and truly, though any manner of cleanliness was due to be taken from him, moment by moment, urine trickling over them, marking the skin, soaking into any light coating of fur wherever it was found.

Nightmare Moon panted, her tail hole flexing around him, though Daybreaker demanded that her lust be sated too. The mare’s eyes flared up fiercely as she half-shouldered the queen of darkness aside, her backside shoved onto Arctic’s face.

“Feel my power, slave!”

She released a blast of gas onto his face while Nightmare Moon recovered, though there would be little needed for her as her magic rejuvenated her sexual desire. Yet Arctic gagged and hacked on her stench as she released a dominating blast of noxious gas over his muzzle, the fumes from her backside sweltering as the pegasus pony’s eyes watered. There was no reason for her abusing him in such a way, especially as she ground onto his cock next, taking his cock into her anal ring too.

She could have just had her fun. But she chose to humiliate him regardless, to show him just how weak he was.

“Little slave… You never fail to be entertaining.”

Arctic’s head spun dizzyingly, barely understanding her, as she took him into her backside, the mare huffing and grunting. Working her arse down on the long pole of colt cock, her burning tail flicked up high, leaving nothing hidden, her marehood thick and plush and gleaming with her arousal and his leaking cum. Of course, she could keep as much of that inside her as she liked, but it was alluring to her too to feel it trickling over her marehood, grinding it down onto his nuts as she faced away from him.

He didn’t want to lose himself too much in the pleasure, as much as Daybreaker squealed and half-kicked out in orgasmic bliss on his cock. He wanted to think of himself as virile, as a stud worthy of the name, able to make them orgasm through anal stimulation alone, but he was a fool, a complete fool. The stallion may have ducked and struggled not to make assumptions, but he was cocky even tied to the chair, the hard, metal manacles closing in a little tighter, tightened with a magical touch that he could not even take note of. The machines were close, too close, and he caught his breath, the mare arching her back, her filthy arsehole pressing down on his cock, stretched wide around his fat, mare-pleasing girth.

He felt it before he realised that they were both staring at him, fangs showing in evil grins. It was a good thing that the manacles were as strong as they were, for the first worming push of excrement grinding into his cock, straining his urethra wide, stole every breath of air from his lungs. Arctic screamed a stallion’s scream, though orgasm was not his to take, neither was he proud of anything in the moment. How could he be when his body was being used and abused in every way by the evil alicorns who only knew how to satisfy their own dirty pleasures. For that, could he blame them?

No… It was their way as they laughed at him, words about how they were going to fill him, stuff him to the brim, bouncing off him. He was not truly present overwhelmed by the sensation of “horse apples”, the rounder, firmer droppings, pushing their way, one after the other down into his shaft. His balls, however, were their first target, even if he did not quite know how they were so easily able to direct their excrement down there.

He grunted, heaving, gasping, his chest tight while his belly heaved and roiled. Maybe he had been wrong to worry about his tail hole that day as shit piled into his nuts, the consistency changing. That much, he could expect, though squishing it through a previously tight tube down into his nuts forced it to squash and press together, the harder droppings compressing, though he felt the weight of them intimately. Even the stench of them relieving themselves washed around him, leaking out around his cock and their anal rings, Nightmare Moon shoving her tail hole back into his face as if she was giving him a taste.

“Lick, slave.”

It was a command given to him as if it was an afterthought to her and he obeyed without thinking. What else could he do? That was all he was, everything he was, a slave to the two of them, his emptied balls now serving another use, a better use. He had not considered why they were draining him, but he might have fought back more if he’d known why – or perhaps not at all. That was not the way of a slave, not at all, his body reacting when while his mind fell deeper and deeper into subservience, gasping at the erotic horror of it all.

There were pangs of pleasure still as his urethra was stretched grotesquely. He didn’t think it could strain any wider than it already was, but, of course, the nightmares proved him wrong every time he thought that something could not be done. Arctic panted heavily, trying to bow forward, but his tongue was too busy sweeping around and around Nightmare Moon’s dirty tail hole, acting as her slave, her toilet slut piss pony in all ways. She released a gush of hotly rank urine over his head, just to show him his place all over again, though that did not wipe the increasing brown stain from his muzzle.

Yellow marks would not be the extent of his debasement that day, not as Daybreaker hissed and climaxed again from the lure of dominating him in such a way. Her backside pushed onto him with raw need coursing through, pumping him full of her excrement, filth working its way deeper and deeper, straining him even as it pressed against his prostate in a very unconventional way. He’d never considered where that tube went inside him, even though it was an integral, important part of his anatomy, though it twisted around to drop into his balls, allowing the bulging of it to grind right up against his prostate.

He shuddered, trying to buck his hips instinctively, for the urge to push back would not be present at such a time, as much as that old scar twinged and pulled within his anal ring, tucked away and not to be made sore, not yet. Arctic heaved as his piss-bloated stomach gurgled yet again, though it was the churning of his shit-filled nuts that made him want to pull away, to serve and yet relieve himself both at the same time.

His tongue pushed into Nightmare Moon’s tail-star, thought it was not clean, not as she relieved herself just a little, letting watery excrement stain her star. The pucker pulsed against his tongue even as the alicorn laughed mockingly, taking full advantage of him in every way, dirtying him, teasing him, taunting him with his complete and utter inability to fight back. His nuts bulged, straining out as lumpy scat filled them, for it was not a smooth round, not like his stomach, as much as the piss and gas in there gurgled and strained to be free. There was nothing much at all that could be free when it came to the alicorns.

His nuts swelled, filled to their normal size, sagging down under their weight, though they squashed against his legs, the feel of a waterier pulse of scat squeezing into him making his head spin. Nothing else existed for him but the filthy dominance of the alicorns, senses awash with dirty scents, clinging to him, even a little filth squeezing down around the length of his cock. He would reek of it for days, weeks, months, his body a vessel, as they had said, nuts swelling, churning, bulging disgustingly. The watery load of scat was a little easier, physically, to take, but his mind still shuddered from it in raw and abject revulsion. He had to, knowing how disgusting it was, how vile it was to have his cock strained and forced to bulge around load after load of scat, all for them to revel in his abuse.

Arctic tried not to pant too heavily as scat clung to his lips, Nightmare Moon revelling in abusing him. Though Daybreaker had to be running empty soon if she did not use her magic. He clung to that thought, the moments of respite that could be his to greedily snatch up for his own, taking while he could. Still, he lapped and lapped, obeying as his nuts bulged, the pushing sensation of the last bits of thicker, heaving excretion making them heave and rumble as if he was able to blow a load. Yet it was not cum and, of course, could not be allowed to leave his body in the same way.

He stole a breath, heaving and panting, trying to wriggle in place to relieve a little of the pressure as Daybreaker pulled off him, Nightmare Moon taking her place. The dirty pucker of the evil sun-mare hung in his vision for a moment before she humped and ground onto his face as if she was using him as nothing more than a rag to clean herself on. There were, of course, more delicate ways to wipe herself off, though Arctic would have been severely amiss to think that she would not take every chance to abuse him.

Pleasure pressed through him as his cock tried to leak, though there was no cum left to drool out, nothing inside him that was not compressed and shoved aside by scat, as much as his body naturally struggled to work to overcome and replace it. He thought his nuts would receive a second helping but it seemed that they were correcting what they had not abused previously, taking his body via his cock instead of focusing on his stomach, stuffing him then from both ends. That was why he gasped and heaved against Daybreaker’s filthy backside, tail hole crammed up to his lips, as his urethra bulged again, straining, pain sparking through even with a throb of pleasure, his bladder taking the brunt of Nightmare Moon’s load.

“Yesss… Oh, it feels so good to relieve myself into a pony again…”

“That’s what the slave is here for, dear.”

Of course, he had no other use but to be used. He panted and stuck his tongue out as he fought to please Daybreaker, as much as everything pressed in on him all at once. The path to his bladder was more direct but that did not stop his body from tightening, trying to push it out, the thick slop of scat not something that could be borne through so easily. It was thick, forcing his body to widen around it, accommodating it, for there was simply no option for him to say no. Even if his body had not been able to take it into his increasingly bloated bladder, she would have used her magic to force him anyway, Arctic panting and heaving, whimpering as he twisted back and forth, straining for some manner of relief.

It was not to come, not as the lumpy bulge under his piss-filled belly rose and rose, his body already not looking like his own anymore. How could it when he was stinking with scat, marked with piss? He was no longer himself, not at all in the way that he remembered, head spinning, his world narrowing. Still, he wanted to serve, as much as it made his guts heave to take scat down into his bladder, trying to tell himself repeatedly that he had no choice, as if that made it any better at all.

It didn’t help, not as his body was forced through the most decrepit of acts, grateful only, in a weak-minded way, that he did not have to taste it. That helped, if only a little, grunting and groaning, lapping pathetically at Daybreaker’s backside, though he hardly noticed where his tongue was anymore. All he knew was that his guts heaved and rolled, straining to take it, his bladder overfull, making him feel as if he was bursting to take a piss, wanting to shift his weight. Yet relief was not to come as watery scat poured forth, sliding more easily through his broken tube, pouring into his bladder to soften the edges of what was already in there, though the bulging lumps remained.

He hung in the manacles, head tipped forward, hardly aware that Daybreaker was no longer abusing his muzzle. His tongue hung out, ready for use, and the evil alicorns stood back, wings lifted, their breasts trembling lightly with the shift of excitement in their bodies. As much as he wanted to squirm and rock his hips, his filthy cock dirtied and stained with scat, he could not, seeking a moment of rest where he thought that it could be afforded to him. Both his nuts and his bladder were overpacked with filth and he hoped against hope that that was the end, that they had no more within them.

Of course, that was not it. That would never have been all.

His flare leaked, thick and full as if he was about to spend a load, yet their lips turned down in the most terrifying of ways.

“That’s not right…”

“No, we can’t have that.”

“Not a drop must escape from the little filth slut.”

Their words washed over him but there was nothing clean about them as he moaned, hips feeling as if they were rocking and thrusting, even if nothing at all was happening to him, locked where he was, leaking and helpless. Arctic whimpered open-mouthed but they lifted him with their magic, carrying something thick and white that crinkled a little towards him.

“Filth ponies like you need to be wrapped up, don’t they?”

His cock ached and throbbed, but he could not understand why it did not soften, lips parting further as he howled with indignation. Despite his submissiveness to them, it was still humiliating, abjectly so, to be wrapped up in a diaper, his cheeks burning, ears tingling with heat, the crinkly material sliding over him. It was soft on the inside with a waterproof layer beyond that, something for little ponies – but he was not little at all! He was a grown stallion!

Yet he had no say in his abuse as they laughed and patted him on the head, though it was harder coming from their hands even then, his crotch bulging thickly even through the diaper, cock shoved into it without a second thought.

“Diapers are traditional for those who can’t control themselves, toilet slave. Didn’t you know that?”

Daybreaker smiled creepily, though that was perhaps as it was so strange to see genuine joy and pleasure in her face. He panted as they taped it up tightly, hiding his dick and equipment, though his stomach ached and churned. Piss sloshed about inside as he turned his head one way and the other, his heart sinking. It didn’t take a genius, of course, to consider what was in those tanks that they had brought in, but the alicorn queens had more dirty play in mind for him still first.

His bladder and nuts ached furiously as they used their magic and their hands to fit him with a deep blue latex suit that was set to cover his full body. At least, that was what he thought, imagining that a full-face mask would slide over his head, but there was only a muzzle to gag him, something shoved between his teeth at the back of his mouth to keep that hole of his open. Arctic did not even fight it, whimpering and whining, the crinkling rustle of the diaper humiliatingly making his ears flick back and forth.

Pinches and gropes had him shivering as they took advantage of him, ensuring that the suit sat exactly where it was meant to, his eyes left able to see, flicking desperately back and forth. It covered even the diaper, though he dared not consider the implications of that, Nightmare Moon wheeling in more tanks and barrels that reeked of waste, marked as such with crude, obscene images and words.

For the scat slave.

Toilet slaves only.

Scat whore load.

Diaper slut droppings.

He whimpered. There was more, not only fresh waste but old stuff too, far more than he could ever have imagined came from the castle itself. Maybe they had gone around Canterlot, in some way, collecting it? Arctic shuddered bodily, wings twitching, flapping, though Daybreaker took care of those, binding them tightly, too tightly, pinned down to his back so that they were rendered trapped in latex straps between his back and the metal of the chair.

“All for you, piss pony…”

He didn’t want to think of what they were going to make him do, the “muzzle” that had been locked over his lips clinging tightly to his face, ensuring that not a drop would escape. He panted and heaved, the rancid stench of scat already overwhelming him, dizzyingly so. There must have even been a septic tank in there somewhere, though he didn’t want to think of where that had come from either. It was too much, too much for him, even if he worried that his limits, finally, were about to be reached.

The alicorns did not care for him, not his comfort, not anything. That was just how and why they had spiked every tank and barrel and pail, after all, with diuretics and laxatives too, forcing the slut pony to debase himself further! That, however, was a surprise for Arctic to come later, something that alicorns held in store, exchanging knowing looks with one another.

“Shall we begin?”

He tried to shake his head but a metal band like a manacle clamped around his neck, pinning him in place to the chair, ensuring that that part of him, at least, remained in place while his stomach, nuts, bladder, every other part of him, was left free to bloat and to expand as they pleased.

The mask allowed various hoses to be connected and they fitted one of the largest immediately to a tank that seemed strangely empty, or at least only half-full. He tried not to react, to appear as if it didn’t bother him at all, but the fear shone through in the whites of his eyes. Another two hoses crammed into the sides of his mouth, curving down towards his own body, though he did not yet know that they fed through the latex suit back, quite literally, to his backside, allowing another tantalising pour of filth to squeeze forth from another source.

Three hoses in his muzzle and so much more to come. Arctic panted and heaved as he tried to close his teeth around what he realised was a thick, heavy, rubber-coated ring gag forcing his mouth open, eyes wide and wild. That could have made it more comfortable for him, but the hoses crammed in there strained his lips even wider, the alicorns giving them all a good shove and a twist to ensure that the mechanism locked them quite securely into place.

“Wouldn’t want anything escaping from our toilet whore now, would we?”

Arctic whined. They didn’t listen.

To be continued in part three…
