Arctic perched nervously at the end of the alicorn dining table in their private quarters of the castle kitchens, an area where the princesses knew that they would not be disturbed. One would have thought that he would be more than used to being there by that point but it was just the way of it for one little pegasus pony to be duly nervous before the princesses, sitting down tightly on his haunches. Even that action was difficult for him, however, considering how his old scar had been aggravated the day before, Celestia wearing him out during the day and using him between sessions at court and, of course, passing him over to Luna so that she had more than enough entertainment for herself through the night.

The pony-pet wore a collar, however, that did not belong to either of the alicorns, even though he was frequently sent to Canterlot to service them, his dark blue mane combed back from his face to hang softly down his neck when he was in a less than dishevelled state. They wanted him to look presentable, after all, as much of a stretch as that was with all the raunchy ways that they made use of the submissive pegasus stallion. And Arctic was familiar with more of the princesses than most of Equestria could have honestly said, which was a rather dubious claim to fame in itself.

Celestia kept an eye on the sun, her horn glowing, bringing it down slowly, though, for her evening meal, she had prepared a particularly large piece of cake topped with pink icing and, of course, her favourite strawberries. Those had been harvested from a speciality farm just outside Ponyville as there was nothing but the best that the princess would accept - and that came to her use and abuse of pony-pets just like Arctic too.

Frowning at her sister, Luna shook her head, her first meal of her waking hours, for she kept different hours to her sister of the sun and day, a sensible meal, though there was a particularly large coffee set beside it, one little-big vice of hers. Celestia, on the other hand... Well, one could not say that she was quite as sensible as her sister in some instances, despite the small difference in their ages.

"Tia, are you really going to eat that? For breakfast?"

Celestia looked up, her mouth already full, eyes wide.

"Whuh? Ithh nothh beck-fasth faw me."

She spoke with her mouth full, even though she could have easily made herself coherent and heard with the use of her magic, eyes glinting with alicorn glee. All her sister could really do, under those circumstances, was roll her eyes and ignore her, though that would not stop Celestia's mischief, as she had so very often found before. Still, she had other matters, "princessly" matters, to attend to before adjourning on her work of the night.

"There have been some interesting dreams lately," Princess Luna said, the alicorn cocking her head and casting Arctic a pointed look, though he could only flick his ears in return, not understanding what she was referring to. "Some...desires coming to light. Would you like me to show you, Celestia?"

With her rainbow-pastel mane dipping and flowing with serene grace, the princess nodded and Luna touched her horn to hers, showing her what she had seen in her dream walking. Dream walking, after all, was not something solely reserved for night hours and there were still some of her subjects, like Arctic that needed to be cared for and tended to during daylight hours, snatching what sleep they could where they would. And what she had found in there, well... There were some dreams that not even the ponies that had them remembered and Celestia's eyes widened more and more as all was revealed.

"Well, well, well," she giggled, shooting Arctic a look that he was only to find out the meaning of later as she parted horns with Luna. "That is something indeed. Is there nothing this one will not debase himself to?"

Arctic shook his head. Maybe he should have known what they were talking about but so much that the princesses said was beyond him and his multiple sessions with Celestia throughout the day had rendered him softly in a glow of subspace too. Better not to worry too much about that, not even as Celestia opened a portal to speak with Nightmare Moon and Daybreaker, the evil halves of the alicorns imprisoned, quite rightly, in the castle dungeons. Regardless of their wicked inclinations and distinct lack of any manner of morality, they still needed to eat and the castle cooks knew just who they were preparing the "extra" meals for, even if they were locked into secrecy with spells of silence.

But it was that little portal that meant that the evil alicorns saw everything as Arctic hustled to obey Celestia's bidding, rushing to fetch the plates that had been brought up for them. He didn't know quite how it happened but one moment he was trotting and the next he had slammed into Celestia's backside, nose throbbing, tail clamped down, pain reverberating through him, the sharpness of his impact with her dulling to a throb.

"Ow!"

As if she had been waiting for an opportunity, Celestia rounded on him, fire in her eyes.

"Little stallion, did you think that a wise move?"

In that moment, she was more like Daybreaker than Princess Celestia, the kind ruler of Equestria that everypony knew and loved. Her mane took on a darker hue, whipping up as if caught by a chilling draught, his bones aching, tail hole clenching - not that any of that was going to help him one bit. Oh no... His fate was already sealed as he scrambled away and blubbered, Luna's smirk going unnoticed as wide as it was, plastered across her face as she more than simply enjoyed the show.

Magic fizzed around him and Arctic was no longer in the palace kitchens but the dungeons - the darkest, dingiest corner of them. Moisture trickled down the walls and his hooves scraped and scrabbled frantically to get away even as Celestia laughed with a cruel edge to her tone, something harder and meaner than should ever have been naturally present there. He was in a cell, not just the dungeons too, the cold, metal bars glistening faintly in the light of Celestia's horn. Arctic whimpered and shivered, ears slipping back, backing away instantly, though he should have already known that such a transgression, well - it simply could not pass by without punishment.

Wrapping a bite of her sparking magic around his tail, she dragged him back, toying with him, Luna joining them even though she had to use her magic to get there, setting a blue illumination orb to cast a tasteful, night-like glow over proceedings.

"No one will know we're here," she said, a smile on her lips. "Time is still, but for the moment. We must proceed..."

His tail released, Arctic gasped, knowing that he shouldn't have tried to run and just not able to stop himself anyway. Fight or flight or freeze... Well, his body could only cling to one of those at a time, instinct overruling what his rational mind knew to be true. The princesses, regardless of all that they and their evil counterparts had done to him, would never truly hurt him, would they? No, no, no - he knew that, he knew it to be true. He had to hold onto that, cling to it, dig his hooves into it and _remember_even as he clamped his tail, muscles shaking, knees knocking together from the sheer fear of his position.

He was going to be punished. And there was nothing he could do to stop it.

"Slave..."

Arctic shuddered. They didn't often call him that. That meant that something far more serious was going down, setting his guts churning, rumbling and bubbling with nervous gas. He tried to quell it but there was only so much he could do as Celestia backed him into a corner, his eyes plaintively wide and ears back, the alicorn managing to tower over him, even though Arctic was larger than most ponies in Equestria.

There was a wall behind Arctic but the stallion as never destined to reach it as Celestia's horn glowed. Maybe he should have stopped, understood that things were no longer going as he may have wanted them to, thought about things in a different way, a different light. He was there to serve and any transgressions deserved to be punished, something that he had been more than well trained and conditioned to think under Mistress Shy's stern hoof. Yet it was not the time for thinking like that, thinking of how things could have been different if he'd been with her, if even he'd paid more attention.

He stiffened, ears pricking. Was there something behind him? Celestia's horn glowed, something catching the corner of his eyes, and even Luna had her eyes fixed on something to his back. Was there something there? His stomach turned over, roiling and rolling sickeningly. Would he even keep his guts in place as his body threatened to rebel, pushing back against even what his mind wanted?

Oh no...

"Go on, slave," Celestia hissed, eyes darker than he'd ever seen them, even the light of her sun wiped away. "Back up more. Escape from me. Where else do you think this is going?"

The mare turned her back on Arctic but that only upped the ante in another way, showing off her thick back end and her heavy udders. She could use her magic during the days to make sure that they were not too much on show all of the time but, well, she had use for them too when it came to driving stallions like Arctic crazy. His shaft pushed from his sheath, his training having conditioned him to respond immediately to such raunchy and lewd stimulus, though there was nothing he could do. He was helpless to resist her allure, everything throbbing through, shaft pulsing, need rising, knowing that there were more watching. Oh, Nightmare Moon and Daybreaker were two that liked a good show and the portal crackled, allowing them some control over what they saw and did, even with the restrictions that Celestia and Luna place on them. Yet them seeing just how far he'd fallen, fearing a punishment as the beat of his heart drummed into a continuous drone, was the least of his worries as Celestia advanced backwards, flagging her tail, showing off the softness of her marehood winking that, surely, he wouldn't get to enjoy and taste in any kind of a good way after all that he'd done.

Arctic shuddered. Had it been that bad, bumping into her? But it wasn't for him to decide the punishment.

However, he knew that things were amiss as she backed him up to something thick and firm, pushing against his large balls - the very balls that had drawn the princesses to request use of him that very first time too. They were large, far larger than those of any normal pony, churning and rumbling with seed, many loads waiting within, though the bloating of them was still to come, he was sure of it. It was a dildo behind him, it could only be the one thing, Celestia's horn glowing as she snatched up his rump in her magic all over again and positioned him just where she wanted him.

He could have stopped but there was only one end to all that the princesses had planned for him as he whimpered and shook his head and obeyed despite everything else. He didn't want to, didn't even like being penetrated under his tail, though it was the pleasure of servitude that made it "worth it" for him. Not that he felt like he could disobey anyway, the tag weighing heavily around his neck.

"Second thoughts there, slave?"

Celestia shoved her rump into his face, forcing him to adore her thick hindquarters, flagging her tail well out of the way so that everything was on show. Her scent overwhelmed him, the sweetness of her sex, and yet he knew too that he had not been given permission to taste her, closing his lips against all temptation. Oh, but she didn't make it easy for him, his thick cock pushing up against his stomach as it throbbed with raw, raunchy, stallion need, trembling with desire. He rocked his hips back but the poke of the huge toy up against his tail-star stopped him, making him tremble in place, teetering on the edge of starting a battle, fighting back, when he knew that he could never win.

To do it or not... That was the question.

Arctic gulped. His mistress would punish him worse than even the princesses if he did not obey.

That was why he backed up onto the dildo, breathing heavily, flanks shuddering, the first drops of sweat darkening his pale hide. He had to do it, for them, or it would all be worse later. The strain and stretch without any lube at all was made only a little easier by fixing his eyes on her rump, watching how her tail flagged, imagining that it was for him. If he was a big stud of a stallion, not a submissive pony-pet, maybe he would have been strong enough to mount and breed the princesses but, really, that was never and would never be his style. No, he was much better submissive, head hanging, broken even then, breath ragged as he backed up more and more.

Yet he could not go further, tears pricking in the corners of his eyes, wondering what the punishment was, for the pain under his tail could not possibly be all that she had to give. No, there had to be more, had to be something else, and he was right to suspect worse still as the mare's backside remained thrust in his face, hardly allowing him space to breathe. Celestia smirked back at him over her shoulder and another wave of fear curdled in his guts, bubbles of gas churning and rumbling as if he had not eaten in hours, although the princesses were careful to ensure that enough "sustenance" went down his throat too. Whether that was "food" of the kind that he would have chosen for himself or not, however, was another question entirely.

She pressed up to him, forcing her teats back against his muzzle. They were already dripping with milk and, at least, in that case, Arctic knew a command from her when it was given like that, locking his lips anxiously around one and suckling, not knowing what to expect. Of course, there was only milk in there but one never knew what the alicorns could have thought of, their horns glowing, promising so much more. He shuddered, the sweet cream of it sliding over his tongue and straight down his throat, throat working furiously to please them. Maybe if he gulped down enough of Celestia's milk, she would forget about punishing him, move into pleasure instead.

Yes... Oh, yes. Where there was pleasure for them there was heaven for Arctic and he swapped one teat for the other, drawing it as deep into his mouth as he could. He had to show her what a good pony-pet he really was, yes, yes, he could do that for her, always for her. Blinking in a flutter of eyelashes, he sank down, drifting into sub-space, that place in his mind where he didn't have to worry about anything other than pleasing his dominant of the moment. That was all that mattered with the princesses above him, Arctic's eyes flicking, half-expecting Luna to make use of him next, standing over him with her particular large and full udders. They had to be weighing on her, surely - why didn't she use a little pony-slave like him to relieve them? His heart pounded. He could be useful too, he just had to show them, drinking down Celestia's milk, tongue pressed up to her nipple for an added tickle of pleasure. If only he could push on that far, maybe, just maybe, things could be different from what they had surely planned for their pony-slave of the castle.

When Celestia yanked her milky teats from his lips, however, udders swinging heavily, he knew that he had been a fool to even hope for that much.

"You should have been better."

Arctic's stomach lurched, the moment stretching out, seconds daring him to try to make an escape, as trapped as he was with his pucker strained painfully. Where could he go? What could he do? They were the dominants of the entire land and to fight back against them, well... There was nothing he could do, nothing at all, overpowering him as the cruelly sweet aroma of her marehood taunted him with all that could have been.

Celestia ground back on his muzzle as Luna encouraged her on, stomping and nickering, telling her sister that "she knew the slut wanted it", though Arctic still did not know what "it" was. Had something in his dreams come to light again? There was no way to know and yet it would have to come to be sooner or later as the mare tucked her hindquarters just a little, rounding her rump, and forcing a blast of gas from her guts.

It rolled over Arctic, noxious and devastating, and he coughed and wheezed, turning her muzzle away even as she grabbed him with her magic, forcing him into place. There was no getting out of it as she smeared her scent over his muzzling, grinding her tail hole down on top of his head, forcing the thickness of the blast into his forelock, his mane, even over his ears. Arctic quivered, only part-penetrated by the toy, though he was well and truly trapped and even, in that moment, backing up onto the toy to get some space seemed like a more appealing notion than staying where he was.

His veins throbbed with fear, gasping and yet not breathing, the mare's guts gurgling as she prepared for more. For not even Arctic would have been so foolish as to think that the princess would let him off so easily as Luna laughed in the background, though even that sound was dim in comparison to the grumbling rise of gas blowing from Celestia's backside. Her tail hole flexed and relaxed, releasing the deluge, though the rippling pulse of sound overwhelmed him, tears streaming down his cheeks.

It was hot. He'd never considered that about gas before but, of course, it could not be cold when leaving the body. The first release of gas had been toxic enough but that had simply been the warm-up for one, long, continuous stream, blasting him in the face as her guts gurgled, overpowering his nose, though he could not even turn his head away. The princess rocked back on his face, the blast of wind rippling over him, stirring up even the hairs of his short coat, dominating him with sound and sight and smell, though he kept his mouth clamped shut despite the urge to cough. No, that would have pushed things too far, on too much, a moan trying to rise but forced down at the last moment.

"Maybe you should have submitted..."

But what did that mean? He tried to cling to it, cling to the thought, as the wave of gas rippled over him, his body getting used to the sensation of it, as new and as strange as it was. His cock throbbed, though Arctic could not have said quite what he was responding to as bile rose in the back of his throat at the same time. Sometimes it was hard to say what was what but he didn't have to know for the princesses to make their use of him, his muzzle wet, not even realising just how much she'd made his eyes water.

His head spun, dizziness overcoming him. Why was he dizzy? Well, Arctic had never been assaulted in such a manner and his hooves no longer seemed as steady as they should have been, tail flicking, the toy under his tail, that couple of inches, the only thing that just barely kept him upright. Celestia was waiting for that, however, as the wind finally passed, the pony staggering and skittering, head dipping, shoving him back neatly and forcibly with her rump to knock him all the way back. The dildo rammed deep, up where it belonged, and he was so overwhelmed that, in that moment, he was relaxed enough to allow it, forcing his passage open crudely and roughly in a way that it should never have been.

"Harder, sister..."

Was that Luna? He blinked dimly but there was nothing before him but the princess' backside, rubbing her dock over his head, somehow still with the lingering aroma of her gas clinging to it. That smell seemed to get into everything and even more so when it came from an alicorn, though Arctic had never before had to face such a toxic blast of gas from any pony, let alone one of them. Her juices smearing over his muzzle were bare and tiny relief from the sick feeling churning in his belly, though he had to hold back the urge to lose whatever he had eaten last, forcing down the bodily desire.

The princesses would be more displeased with him than ever if he gave in to that, yes... No. No, he could not, moaning open-mouthed as he finally gave in, parting his lips to suck in what air he could, though it was still woefully tainted with a thickly pernicious scent that could have quite duly knocked out a yak.

"Holding that in all day," Celestia said with a groan, "oh... Oh, slave, you don't know how hard that is. But I have to be their princess, have to maintain my image. This though... This a slave like you likes."

Luna rolled her eyes, though not at the reference to the quivering Arctic.

"Your diet doesn't help either, sister."

"Shut up."

They bickered over him, Arctic merely a toy to be passed between them as they pleased. The two of them ignored the evil alicorns watching for their play was the sort that those two would likely join in on later, when it pleased them.

"Don't get too comfortable, there's more where this came from."

Arctic's head swam though, for once, it was not due to any manner of being sexually overwhelmed, trembling in place. He was pinned - pinned and penetrated. Just what did a pony like him think that he could do about it? They were huge, so much so that even their bodies could pin him, as big and as strong as he was, naturally, as a pony. It was his submissive inclination that rendered him completely and utterly incapacitated to push back against anything they wanted, doing their bidding day in and day out. Mistress Shy had been the first to recognise that quality in him, truly, even after all that had happened to him before, though the headiness of Celestia's ever so slightly still musky taint pressing over him was enough to remind him of his place right there and then nonetheless.

Celestia, however, was not idle, her stomach rumbling, releasing more wind as her guts churned. It was all deliberate, very much so, and a part of the pony-pet still could not blame her considering that she'd mentioned something about holding it in all down. The blasts of air rippled over his coat and he was forced to keep his head still as she bore back on his nose, releasing the foul-smelling gas directly into his nostrils, forcing him to take every last bit of it, no longer simply drenching him in her rancid stench. Indeed, that clung to his mane and was so deeply woven into the fibres of his coat that there was no easy way to ever clean himself of all that ever again, though that was a problem for later.

However, there was one more thing that Arctic had not considered as her tail hole clamped down around his muzzle, easily taking it inside before tightening her muscles again, squeezing around his nose. He could still breathe but, well, any breath that he did get into his lungs was full of the gas and there was nowhere for him to exhale, his lips parted and forced there as she let out a long, rippling fart. With his mouth parted, it eased down his throat, working and gulping, though his lungs could not take it while his stomach could.

The first thing that he realised was "wrong" was the tightness in his stomach, how the air filled him, forcing him to feel full as if he'd just eaten a large meal. Or perhaps, more accurately, the last time Mistress Shy had shoved a hose down his throat, hooked him up to an air pump, and left him there until he was fit to burst from her dungeon. The pony shuddered, hardly able to open his eyes, struggling and flailing to no avail, tail flicking against the wall. Although he was not rocking or grinding on the dildo rammed up under his tail at all, he felt fuller all around, every part of him swollen and bloated mentally even if not physically. No, that was for his belly alone as she forced more and more gas into him, rippling pulses of relaxing muscles driving it forth, laughing at his debasement, the position he had been forced into.

He couldn't move! It no longer mattered that he was not wearing any bondage gear of any kind, only that the gas bloated him out more and more, incapacitating him in such a bodily manner that he could only wriggle, his belly unbalancing him. Maybe they should have chained up him in the cold, damp, dingy dungeon but Celestia had already known just how she was going to restrict him, using and abusing him as her gas forced him to swell.

"Oh, little slave, you didn't think we were going to go easy on you, did you?"

The stallion tried to grunt but her tail hole closed around his nose, forcing every last breath of gas into him, rippling and bursting, pulsing against his snout. It was too much, he couldn't do it, heaving and whining, even though he knew that he would not be heard. It was the way of it, simply how things were for a pony of his station, wings fluttering out weakly even though he knew the bars would not permit him any manner of escape. It seemed to pull him down, make him feel weak, though he could not have said quite how that was possible, regardless of just how much he twisted and tried to evade the growing, swelling strain.

"What more came from your dreams, Arctic?"

He didn't know, could not know, every last one of his senses overpowered as he could even taste the gas, his stomach heaving, though it could not throw up or his throat even retch with so much going on. He was prey to them, a slave to them, slipping down and down and down as the pegasus knew that he could only do one thing: submit. There was only submission for him even as the heat of her enveloped him, tail hole sucking his muzzle even deeper, all the way up to the point in his muzzle where it curved up to his eyes.

Arctic struggled, wriggling and squirming, though he may as well have not been doing anything at all for all the good it did him. His head felt like it was twisting back and forth violently but, truly, all he was doing was twitching a little, a little jump in the muscles of his jaw. Without forcing his nose back out from within the tight grip of her tail hole, there was nowhere for the gas to go as she pumped him full, his guts and belly bloating out smoothly. The only tiny thing that Arctic could be thankful for was that he was used to the inflation, the smoothness of it pressing out against his stomach, his belly rounding out nicely. It made his cock throb all the more deliciously, though he was delirious, losing all sense of where he was and even who he was as the fabric that made up his world changed around him.

Yet something more was coming, his lips forced apart by the pull of muscles in her passage, forcing something into his mouth. It took the mind-boggled pony a moment to release what was happening as it pushed into his mouth, the taste hitting him a moment later, thick and sordid, reminding him, only in passing, of what her last meal was. For the pulsating farts and breaking of wind had to come to an end sooner or later as Celestia let out a long, low moan of absolute relief and defecated straight into his muzzle.

"Ahhh..."

It was not as he'd wanted and a far cry from the heaven of suckling down mouthful after mouthful of sweet milk from her teats, the taste and feel of it crude and sickening. Yet there was not even any option to reject what was being given to him as he finally realised, too late, that Celestia was a little plumper than usual. She was a good head taller than him and, frankly, he had been so caught up in serving her needs during Day Court that he hadn't taken note of another need that he never saw her relieving and she now was using his body for in full force.

The portal for the evil alicorns crackled as they clearly sussed out that something was going on in another part of the dungeons, even though they could not actively leave their cell. Daybreaker reeled visibly as she looked down on the scene, thick logs of half-solid droppings worming their way down Arctic's throat as it was forced into his stomach along with the hefty dose of gas that had already bloated him up. His cock was no longer visible as it was squashed down to the ground under the lump weight of his stomach, the sensation of something forcing its way down his throat again and again, only allowing him to snatch toxic gulps of breath from time to time, only enough to stop him from passing out. The alicorns, after all, wanted him to feel everything as Princess Celestia used his body for her most intimate kind of relief.

"Celestia, that is disgusting..."

"Why not use the portal?"

"He likes it still..."

The alicorns, as shocked as they had been to see what was happening, were just as depraved in the very best of ways, after all, as Celestia and Luna and it would have still have been impossible to ignore Arctic's arousal. He didn't want it, oh no, but his body told the truth for him, cock drooling pre-cum as the droppings squeezed into his mouth, breaking down around his tongue, his throat working constantly to gulp them down. He didn't even know whether it was Celestia forcing him anymore or if he was actually doing part of it of his own free will, although even that was not something that the submissive slut of a slave had to worry about while he was merely being used as their toilet.

He was nothing more than that, maybe had never been more than that, swallowing hard and holding that "feeling" there, tightening his throat. If he held off, he could not take any more down his throat, he was sure of it, his cheeks filling with excrement as she forced more and more of her scat into him. Celestia grunted as she bore down, most certainly not accepting "no" for an answer, though there was a manner of force to it.

He would submit.

Arctic should never have fought back as her droppings built up, the rancid stench washing over him even worse than the gas she had forced into him. What she'd already deposited down his throat churned and rolled in his stomach, fat, heavy logs of scat becoming more and more solid as she went along, though he didn't want to think about the stomach-churning, retch-inducing liquid that had flowed up and around his tongue was not something that he wanted to let his mind linger on too much. Even then, he wanted to heave and empty the contents of his stomach, get it all out, as she forced her way past the barrier he'd put up, his throat opening up to take the logs of scat, lumpy and roiling, coiling their way down into his guts.

Yet nothing was under his control as his face grew more and more stained, scat slopping down his face as Celestia finally pulled off his muzzle, because it was not as if he was going anywhere. Without clamping her tail hole around his muzzle, she could deposit greater sizes into his muzzle too and wiggled her rump tenaciously back in his face as if to taunt him with what would never be his in the debasement of it all.

"You wanted this... Look what you got!"

Even Arctic could not truly say anything back to that as he trembled in place, his front hooves splayed, half-liquid droppings slopping messily over his nose, the reek too much for even him, he tried screwing up his muzzle but the alicorn princess simply was not going to allow him to wrench his head away as everyone watched on, curious to see just how far he could be pushed. Rapidly thickening and solidifying piles of scat pushed their way down his throat as she clamped her tail down over his head, holding him there with her magic, though his struggles were so weak, regardless of how hard he thought he was fighting, that she hardly had to use any of her powers at all.

He was just that weak when it came to standing up to the princesses, his every raunchy, sordid desire revealed in the dreams that the poor pony had not even remembered on waking. That was just how Luna had realised that there was something more that they could use him for, finding him asleep and his cock twitching, drooling cum but not quite blissing out into orgasm even in sleep, his training holding true. Whereas he did not remember the dream where he'd swallowed pile after pile of shit direct from the source of a mystery mare's tail hole, Luna had filed it away for careful reflection, the wickedness of their desires something to be teased into the light again and again too, however they pleased.

With alicorns, there were no limits.

She forced a thick, continuous coil of scat down him, bearing down viciously on her body and his muzzle. There was only one place for it to go as he gagged and tried to even push it out with his tongue, but that only served to get even more of her sickly taste into his muzzle. Arctic could not even remember just how her marehood tasted when he was subjected to so much, able to feel every last inch and twist of the long rope of shit as it wormed and twisted its way down his throat into his stomach. It was like a tentacle, in a way, but that was no longer a comforting thought when his ability to breathe was cut off.

Hold out... Yes. Yes, that was all he had to do, stomach heaving, his body rebelling even as the alicorn forced her way so very easily past every last one of his defences. A retch was just another opportunity to shove a thick log of scat down his throat, more making way for even more, his belly lumpy and engorged, squashed down to the ground around his cock as she forced him to take it all. The evil alicorns watched on hungrily, Arctic aware of their presence as they commented on what Celestia should do to him, saying that she should keep him under her throne to relieve herself in the day too, just so that she never had to go out. Of course, they were not concerned in the slightest with Celestia's comfort, only what they could force him through.

Arctic weakly struggled, the light brown smears over his muzzle darkening as different parts of her daily meals slid into him, feeding him in a way. It was not much of a feeding as she kept him there, speared onto that cock and trapped against her rub, another blast of gas rippling through her with a wetter dose of droppings. They were not quite as solid there, even as the consistency slackened off, and Arctic whimpered and blubbered through the encroach of shit, neither of the princesses caring one bit about the mess that he was leaving on the floor, for what he couldn't get down his throat. That could be dealt with later, whether they made him lick it all up with his tongue or even simply magic it into his belly. It would sit there nicely, filling out the spaces between the thicker ropes of excrement, filling in all the gaps, his stomach gurgling and bloating out noisily as Celestia prodded his gut with a hind hoof.

"Hm... You still have room in there."

No - no, he didn't! Arctic's head spun, reeling and tipping, the world swaying sickeningly around him. The need to retch was overwhelming but there was no end to the debasement, scat slopping down his chin, Celestia even lifting her hips to deposit a steaming pile over his head, rising with heat from just being pushed out of her body. It shoved his head down, although it could not pin his head to the ground, considering his position, the weight of it tipping his head from one side to the other. Arctic moaned, trying to dislodge it, but Celestia only "rewarded" such an endeavour by pushing out another load, plopping pile after pile down onto his head to smear into his mane, clinging darkly to the hairs, even getting into his ears. There was not a single part of his body that did not feel dirty and stained and covered in shit even though she had not even moved on to the rest of him, the pristine white of his coat so tempting to sully. Why, it was a wonder that they had not brought up Arctic acting as a living toilet full-time with them, considering all the watersports they too had engaged in!

It was a good use for him, some may even have argued the very best use. A piss-pony could only go so far but a scat-slave, well...that was all the way. Arctic squirmed back on the dildo, that pressure and pain no longer seeming significant at all as the evil alicorns, that infuriating pair, commented out loud on all the liberties they could take with him next time. Arctic's stomach gurgled but that was not even noticeable as Celestia broke wind again, grinding her taint right up to his lips once more, forcing him to take the runny droppings down as he gasped. He was not gasping for her, however, just to get air into his lungs, though it had the added "happy" effect for her of making him seem as if he was deeper into his submission than even he was.

More and more poured down his throat as Arctic's neck seemed to bulge, the logs of shit thicker than ever, his belly heavy with scat. He had to widen the stance of his hind legs just to stay in position, for he did not want to put his full weight on that dildo. No harm would come to him but pain was pain at the end of the day and one sensation could overwhelm another in the wrong kind of way too if he was not careful about monitoring just what was happening, at least in that manner. His stomach brushed the floor around his cock, hiding the fatness of his girth as his lumpy belly bulged out and out, Celestia proving to have quite a load within her, though, even then, Arctic dimly thought that there was some manner of magical influence at play.

She farted, splattering wet droplets of shit over his muzzle as he gasped and heaved, abdominals tightened, throat closing up, his body fighting back even as his mind sank. There was nothing to be fought back against but, sometimes, the natural reactions of the body simply were not something that could be pushed back on. It was fortunately unfortunate, in that instance, that the princesses were more than well-equipped with magic to push him past any natural limits that may have tried to come into play.

"Slave, you should not spill it..."

Using her magic, Celestia scooped up what he had not managed to get down his throat (or some of it, at least), forcing it between his lips as she hooked a magical "tendril" into the corner of his lips. There was nothing Arctic could do but accept it, as much as he grunted and twisted, trying not to think too much about what he was swallowing, as much as that in itself was utterly impossible to ignore.

"Take it all..."

She forced the droppings into his mouth, feeding him with her magic as he hacked and gag, sides trembling, the magical tendril forcing him to keep his mouth open as much as he wanted to clamp his lips shut against everything that was still coming. The coils of shit in his belly seemed to wriggle back and forth just like tentacles and his head pounded, vision greying, losing his grip on reality as much as he didn't know anymore whether he wanted to be there or not. He was there and he had to feel everything, how his body succumbed to it, cock flexing and twitching, on the edge of climax. For there was some part of him, even if he didn't honestly want to acknowledge it, that lusted for their treatment of him, falling all the way down to the lowest of the low. He didn't need to be under their marehoods, the sweetness of their mare-ish femininity, to know his place when their tail-stars promised so very much more for a slave-pony like him.

Had he been a pet? His head swam, leaving him not knowing what to think as more scat still was forced into his throat while they toyed with the dildo under his tail. Whereas Luna had not made herself an active participant so far, merely watching (he was not so much a fool as to think that she was there to make sure that her sister did not go too far), that was about to change. The toy shifted shape inside his backside, shifting to anal beads that reminded him of the more traditional shaped "horse apples" that Celestia forced into him, though her excrement did not truly follow the usual forms for ponies. He supposed as an alicorn, there was some level of control that she had there too but he did not know the full extent of that - not yet.

The beads pressed up against his backside, swelling as if they were being inflated and pumped up, tightening with a sharp increase of pressure. He tried to clamp his tail down but that was, really, not so much something that was going to help him, the beads shifting to a flared stallion's shaft with a thickly bulging tip and back to a normal dildo, the tapered tip no longer needed for penetration. Yet it was all a matter of control in twisting it to suit her uses and, of course, entertain Luna too, reminding him quite clearly that his body was theirs, for the time being, to do with as they wanted too.

"There's more..."

But not much more, Celestia teasing him, her tone softening just a little as she packed her scat into him. He'd been shown his place, after all, and there was nowhere for their slave of the moment to run off to, so why keep on a harsh face when she could enjoy herself too? Her hide trembled, body shaking lightly, relieved to finally get all of that out of her while his belly bloated out massively. It was a far cry from the inflation that she'd seen him pushed through before but, well, sometimes one did not have to go that far to see the desired effects. Her marehood pulsed and twitched, catching his attention, Arctic trying to lean into it even with brown stains splattered down his chest, his legs coated all the way down the front.

"Perhaps you have earned a moment of your own relief..."

His heart lifted and he dared to turn his muzzle up for a moment as her tail hole closed up again, returning to its comfortable, natural tightness while he clenched down around the vibrating toy in his backdoor entrance. It was nothing worse than what had already been done, even though his stomach gurgled and burbled with discomfort that could not have been ignored, but the hosing down of his muzzle with piss sent him gasping too. He twisted his head back and forth as she washed him down, marehood flexing and pulsing lightly as she released her need. The slit of her urethra was tucked within her marehood, which was one of the reasons why she had to "wink" it after urinating, a self-cleaning method, the throbbing nub of her clit well enough on show.

Arctic fixed his eyes on it even as she soaked his sodden forelock down between his eyes, tongue pushing out, a moan on his lips. Yes, that was a better thing to focus on, though the strain of gas rumbling in his stomach was still something that needed due attention, his guts aching painfully. Best not to think about that, to worry about that, not too much, to push on, to please her, to do everything that the princess of Equestria would have him do. It was his place, where he was supposed to be, and that was just what allowed him to submit to it, not delving into whether he wanted it or not, toeing the line and yet unsure which side of it he'd rather stand on.

Some things were best left untouched.

His pale fur was already stained but Celestia had so much more piss to wash him down with, her bladder swollen and ready to deliver all the coffee that she'd drunk that day back out of her body in a natural way. He tried to spread his hind legs but he was too stuck on the dildo to manage it, the vibrations travelling into that tentatively sensitive patch of nerves in his tail hole, the bit that could, fairly, be pleasurable, if stimulated in the right way. He may not have liked anything much under his tail but he could find some manner of eroticism in it too if the time was right, wiggling his hips a little and moaning as Celestia forced his lips up to her marehood.

Of course, she was not demanding pleasure as she was already taking all of that that she could ever have needed from him, but urine did just as well as scat to fill his stomach, bloating him out wickedly. He obediently locked his lips in close to her marehood and sucked it down as it filled his mouth, gulping loudly as if to show them what an obedient pony-slave he was at the end of it all. Celestia's magic wrapped around his cock, forming a second layer of "skin" in a glowing, magical garb, able to slither in there despite the bulge of his gut, how it bloated out terribly.

Piss slopped into him, filling in the gaps around the droppings filling his stomach, softening the appearance of his gut just a little, though there was no relief to be had in it for Arctic. As much as the pony squirmed, he was still very much stuck right where he was, panting and sucking in what breath he could through flared nostrils, the reek of shit still permeating the air. It was in him and on him, clinging to him, though he was relieved too in a way to return to the depravity he knew in letting her treat him like her piss-pony, something that he was more familiar with in the real world rather than his dreams.

His cock though... Oh, it was impossible to ignore that pleasure as the stream of urine flooded down his throat and pooled in his stomach, softening everything, breaking it up so that there was room for more. The strain on his gut was no longer quite so great, only a little bit easier, but it was that ease that allowed him to move, stroke by magical stroke, to orgasm. Celestia milked his cock with his magic, cooing to him, even though there could still be no question about it as to who was in charge. She could be gentle when she wanted to if it served her purpose and Luna changed the shape of the toy under his tail to one that ground up against his prostate, forcing his body to reply with ecstasy.

He screamed through the stream of piss flooding his muzzle, spilling over the edges of his lips and between his teeth, wanting it all, needing it. He couldn't have said how long it had been since he'd last climaxed but the pleasure was tantalising, drawing him in, making him want it even more as his seed splattered the floor. Throb after throb of cum left him in the pulses of ecstasy, head spinning, though he could not ignore the reek and stench of the dungeon, the debasement that he was being put through. There just didn't seem to be anything else he could do but to try to find something there that made him moan in joy too, legs braced and hips rocking, even grinding back in fits of lust on the prostate massager too as it vibrated and pulsed.

"Look at him..."

"Such a slut..."

"This is all he deserved..."

He caught snippets of what they were saying, his audience, but it did not matter, not even as they plotted out loud what more to do to him, Arctic forgetting what had happened for a minute and licking his lips. That was something that he immediately regretted but the press of Celestia's marehood grinding back onto his lips begged his attention and he slid his tongue into her with a sigh of relief even as she doused him in yet another stream of piss.

"You're broken," she said out loud, toying with him on the edge of another orgasm, holding him there. "Why don't you give in?"

He had given in though, that was the truth of it, the alicorn's horn glowing gold as she spread her wings, relishing in the power, the dominance in sexuality that she could embrace and embody. There were few ponies in Equestria that she could relieve such needs with (sweetness and kisses got boring after a while) and Arctic was the perfect pet or slave for that, depending on how they wanted to use him at that moment. Pulsing her magic, she forced him over the edge all over again and he cried out plaintively, painting the floor with another load of cum even though the prostate massager under his tail was doing a good job of milking him of his cum too. There was pleasure in it, however, for him and his playful mind, bouncing between submission, humiliation, pleasure and ecstasy, would never cease to entertain her, her sister rubbing her jaw as she added her magic to the mix too.

"Such a ready cock," Luna murmured, shaking her head, though the wonder in her tone was admiring too. "He's ready. Everything is as I saw in his dream, sister. Let's go all the way - the dimensional pocket will be ready and waiting for us."

Arctic blinked but he couldn't see, wrapped up in a glow of alicorn magic as they plugged his ears. That didn't matter too much as it dulled his senses, allowing him some relief from the stench as his cock was smoothly pumped and milked to a third orgasm as if his climax did not matter at all. He was just something for them to entertain themselves with, like a fidget spinner, something to keep the edge of their magic engaged while their minds worked away at humiliating him, bringing him down to such a level of debasement that they could push him even further. For that was all he was there for, after Mistress Shy had allowed them to borrow him once again, his tail flagged and the toy under his tail swelling all of a sudden into a huge dildo that pressed up against all the right-wrong spots, sending him into yet another orgasm as his seed flowed freely.

And then he was wrapped up in light, hooves lifted from the floor, the dildo left behind, a flash of teleportation magic taking the slave-pony just where he needed to be. Well, where the alicorns wanted him to be, although Luna knew more about Arctic's own dreams and desires than even the poor stallion himself did. That was to his detriment and his benefit, however, as his limits were pushed beyond what even he thought possible, his body bloated on piss and scat and gas, everything churning and grumbling up together in the pit of his stomach.

With his coat dirty, Arctic blinked into wakefulness in a place that did not look at all like the dungeon that he had been swept up and away from, turning his head back and forth, not understanding one bit why he was there. Everything looked brown, which was a shade, indeed, to match his grubby, stained coat, the pressure released under his tail, although the pucker of his rosebud was slow to tighten up again. Maybe his body knew still that it would be needed and hung onto that looseness and flexibility for him, though Arctic was still not to know just what the princesses, away from their evil counterparts for once, as much as they liked to watch, had in mind.

When he realised what he was doing and where he was, however, the poor pony in question could only reel, hooves skittering, though it was too easy for them to flip him upside down on his back. Their plans had been made while his ears were plugged and he was enjoying the last orgasms he would have for a while, even though whether he climaxed or not at that time was not something that would stop them from getting what they needed from him.

Piles of shit filled the room, though the walls were brown too, making it seem as if there was no end to it. The mystery of "where alicorns popped" (soon to be a comedic Manehattan show, a joke on the fact that no one had ever come across them in any bathroom or manner of reliving themselves) was revealed as they had somewhere, that inter-dimensional pocket access with their magic and a portal, to put all of it. Celestia and Luna did not have to worry about going to the bathroom during their duties as they had somewhere to simply transport all of it, ensuring that their needs were taken care of away from the limelight in a fashion best-becoming ones of their station.

There was no rancid stench that was overpowering but still a thickly musky undercurrent to it all, Arctic mumbling and squirming as Celestia planted her rump against his muzzle, wedging him against one of the mounds of shit and her body. She had him right where she needed him and still bore back, the pony screaming, his head disappearing under her tail as her tail hole stretched and strained around him. Arctic knew what happened in there and, still, he could not help but resist, fighting back in the heat of the moment while Luna locked a pair of manacles and hobbles around his front and hind legs respectively. Those had not been in the dream but, well, an alicorn could only improvise where needed and able. They wouldn't have wanted him to get away, after all, when there was still so much for them to take their pleasure with, involving him and his dirty little fetishes.

Arctic fought and kicked, chains clanking, but there was no getting away as Celestia's tail hole closed around his neck, almost tightly enough to cut off his air supply. There was still a way for him, however weakly, to breathe in there, but it was difficult and did not come easily without a touch of Luna's magic at play too. Arctic did not need to be privy to that, however, as scat pushed into his mouth, sliding slickly and thickly over his tongue, his throat forced to accept it. It coiled down his throat, seeming to twist back and forth like the thick girth of a living tentacle or even a fine, his guts aching, churning, trying to rebel. He should have known by then that his fighting was in vain, cock throbbing weakly, spilling pre-cum even though he had only just gotten off. Considering all that was happening to him, Arctic but a passive player in his debasement, he may as well have done nothing at all.

Ropes of thick, almost slimy droppings pushed down his throat, twisting down into his stomach and giving him the impression that they were pooling in there, the coil thick and unwilling to yield. The scat that was already in his belly sloshed about with piss and bloated gas, though his stomach was still lumpy and swollen, appearing as if he had, perhaps, been filled with eggs of all different shapes and sizes. The stallion shuddered, though his mind could not linger on another humiliation, however hypothetical it was, for too long. Maybe that would give them more ideas if he did not wipe it from his mind.

Still, the feel of it dominating his tongue could not be ignored, how it squelched down between his teeth and flowed around his tongue, the appendage striving, even then, to do what it thought was natural and right in wiggling and helping to push the excrement down his throat. Celestia laughed as she let out another blast of a fart but the noxious gas was not enough anymore to render him dizzy and swaying - anyway, he was already lying down. Just what more could that manner of treatment, even as it ruffled his mane, her tail hole rippling and pulsing around his neck, do to him?

His stomach ached but he could not evade it, feeling out it bloated out, swelling up and up, though the inflation was still within the bounds of what his body could handle, at least for the moment. It was not as if he was being pumped up to parade-balloon sizes all over again (something that Mistress Shy took great amusement in) and it was not as if it was not something he could bear through. The pony tried to grit his teeth but there was too much scat in the way, the potent taste grinding headily up into the back of his mouth and throat as she forced him to accept it all.

All he had to do was to hold fast, he thought. It would be over eventually, regardless of just how his cock throbbed so very tenaciously and wickedly for more. That part of it, well... Well, he wouldn't spend too much time thinking and worrying about that.

Luna, however, was set to change that and was not idle, taking her leave and liberty of him as her guts ached to relieve herself too. His position allowed her to, deviously, place herself butt to butt with him, tail flagged so that the contact could be as close as physically possible. His tail hole had been strained and stretched by the dildo already in preparation for what was to come, although that was by no means for his comfort but so that she could force as much into him as her body and magic had the capability to demand. For there was more than one entrance to his body that could take such a dirty load and sullying such an impeccably clean tail hole was truly only the start of it.

The first he realised that something was different was the pressure on the rosebud of his under-tail. He tried to clamp his dock down but there was something in the way, though it did not feel like a dildo - and he would have known what that felt like after all his experience with them. He tried to roll away but that only shoved his nose up even more deeply into Celestia's tail hole, gasping and gulping and whining and trying to be heard to no avail. Yet the encroach of Luna's scat was not to be denied or ignored as it pushed up more and more deeply into his anal passage, shoving deeper, curling by his rectum. Nothing stopped it as it coiled up deeper and deeper, reaching depths of him that dildos had not even squirmed into, for they were not designed to penetrate soft tissue without causing damage.

Princess Luna moaned, rolling her head from one side to the other, her horn aglow with a sheen of her magic. It was not so for her, her droppings worming their way into his intestines and throbbing there, his body trying to push them back out. Yet Arctic's body did not know what to do, what it could even possibly do to think of getting some semblance of control back, for none of it was for Arctic to worry about even as his stomach bulged, a different kind of lumpiness gracing his lower abdomen.

The stallion fought and squirmed, jerking and flopping weakly back and forth, the manacles clanking without any sense of rhythm. They sent a chill of fear into his heart, however, the iron fist clamping around it as if even Discord was there, setting off his own brand of chaos simply to turn Arctic's world upside down. He vaguely remembered a time when he had, indeed, had thick vines worming their way up his arse and through his body but something had softened the edges of the memory, perhaps a potion of Zercora's. Fluttershy had been known to give him those sometimes when things got too hard for him, his mind shaky and needing a sense of stability after a particularly arduous session, even though he knew he'd always consented to it. Knowing that it would be brutal, however, and yet not remembering all of the details had his spine aching, tingling with icy fingers, claws raking down his back in the bindings of his imagination as the bulges increased more and more.

The princess of the night groaned, rocking her hips from one side to the other, though Celestia was more than in her element as she sought to empty the very last drops of excrement into her toilet-pony of the night or day... She didn't really remember whether it was day or night anymore, time having no meaning in the dimension that they had slipped into, somewhere where they, indeed, could remain forever too, if that was what they wanted. Her pastel mane and tail seemed out of place in such a sordid activity as she used her magic to create a tighter seal around his neck, ensuring that no gas would escape as she let out yet another ripping fart.

Arctic gasped and really shouldn't have as she tried to choke him of air, forcing the gas into his lungs. There was no way, surely, that she could produce that much, though the only meagre blessing of her gassy bloats blasting forth was the fact that the stream of droppings paused for a moment. It was scant relief, however, as his lips were forced open, taking the bloating gas into his stomach. What Luna was dumping in him too had reached his stomach, sloshing and dropping through a sphincter into his belly, piling up and mixing with gas and piss to create a truly deadly concoction.

His belly smoothed out, four times the size of his body and growing more, although it spilt more to the sides of his body rather than rising like a beach ball, as so often was the case with his usual manners of inflation. His cock jutted straight up in the air as Luna ground back against him, tail sweeping over it and his balls, but he could hardly think about that as his stomach rumbled and smoothed out with the pulsing force of gas filling him more and more. It was respite, in a way, from something more, but not any kind of break that he was willing to lean into as if it was a relief, the stench of it wrapping around him. It was devious too, not employing much pressure as it moved down his throat, yet the pressure in his belly was impossible to ignore, how bloated and overly "full" he felt.

Arctic groaned. Yes... It was the feeling of being too full that the gas brought, not the heaviness of scat and piss, which were both easier and harder to bear in equal doses. His belly swelled, trembling with each rippling fart, the princess breaking wind as if it meant nothing at all to her, flanks shudder, though he could not see what he had done to her body too. She was lighter in herself as she bore back on his head and ground onto his body like the living toy he was, moaning as she revelled in the moment, the absolute release of relief that using him in such a way brought her.

"Unnff... That's the stuff..."

Simpler, cruder language was more her forte when undergoing such a rancid act, her heart pounding harder than ever. Her stomach, just before her udders, bulged out where his head was shoved, the pony disappearing inside her up to his withers and shoulders, more, always more. Celestia's magic gripped his cock and she smirked to hear him moan, driving her on, though she had not yet taken any sexual pleasure from him. The use of him as her living toilet had been simply too good to pass up the opportunity to do.

Luna, however, had needs to attest and tend to also, using her legs to hook herself more tightly rump to rump with Arctic, her tail flicking over his nuts. She had to drag him up a little to her level and form a tighter seal, much as Celestia had done, with her magic, though it would be needed for what more she had in mind. For the churnings and insidious "rippling" of bloating gas had puffed out her sides too. A princess, after all, could not break wind in public and even in the privacy of their chambers, well... It was a habit, so to speak, that Luna had had to temper down just a little to make sure that she fitted in with Equestrian society or at least did not consistently get invited down to the farm bars with rough and tumble sorts of stallions.

The gape of his tail hole helped as she pressed up to him, passing gas with a groan that almost came out as more sexual than anything else, wiggling her hips back to him, the filling of it pumping through his intestines. If not for her magic, it may have passed straight back out of Arctic all over again but the pony, in such a position, was forced to take it all. His cries were muffled by Celestia's tail hole but his pain and debasement was still clear to see as she filled him. It shot through his innards and poured into his stomach, though Luna did not solely have the goal of bloating him up, releasing the seal and drawing back only a touch to blast another pulsing fart over his hindquarters and his balls.

"Unnff... Oh..."

It was a crude sort of groan that Princess Luna unleashed but there was no one there but Tia, not even their evil halves at that time, to bear witness to how she used and abused him, washing down his backside in her fumes. It was a relief to finally let it out and she let the heat rise over his balls, which lay just over her backside, her tail pushed up with the dock against their soft roundness, curling and teasing, the sensation pleasurable in a way even if the reek was not.

It was not too much, however, to a pony that had been put through far worse so he bore through it bravely, even though Celestia was still trapping his head, holding him there for Luna, her dear sister. The younger sister of the night had more than he needed and used her hooves, flexible to a fault, to knead one of them teasingly, though his cock would have to be left out for the moment. Her magic could have brought it climax but all she had for him was the wrapping of her magic with Celestia's, pumping his length and denying him climax even though that was something that would have tenderly eased the pressure within him in a good way.

Luna smirked, a little more of her giving in to the raunchiness of debauchery. It wasn't for a pony-slut and slave to have good things all the time.

She wasn't done with him yet, however, Arctic wriggling and flexing his rump, the muscles there enough to hold him steady, tail flat to the floor as his body was abused. The heat of her pouring gas was something that dissipated but the crawling sensuality left in his body, the bulging and rippling... His head fogged up, the pony in question shaking it within Celestia's body, not knowing what to do, where to go next. There seemed to be a confusion spinning his head one way and then the other, perhaps a lack of oxygen. The inflation, for a moment, almost felt pleasant as he wriggled his hips, though the churning bubbles in his gut were unlike anything he had had before.

Arctic blinked, the flesh of Celestia's backside, musk fading, closing in around him. Where was he? Yet a slip in consciousness, darting between the waking world and the one that he was not quite as used to under her tail, was not going to change the mention of his reality, Luna crushing her backside back to his with a magical seal and letting rip. Her magic still teased his cock but the clamp of it around the base stopped him from climaxing amongst the piles of shit that he could not even see anymore, forcing his ejaculate back into his nuts as his shaft throbbed and jerked with raw and wanton need.

Yet it was a need that simply was not destined to be satisfied as Celestia bore back against him, filling his mouth all over again with wet droppings, slick and damp and pushing insistently over his tongue only in one direction. Luna's fart bloated him up, stretching out his colon, his intestines, every last bit of them plumping up and swelling, inflating him from the inside out. Arctic howled through a mouthful of scat and wriggled, his stomach tight and heavy, churning and gurgling, yet there was nowhere to escape to as he was filled with dirty air. Thickly musky and rippling on, her release of wind went on and on without a break, flanks shuddering a groan that went unheard. For the relief of it too was something that Luna had to take into account, his guts puffing out, filthy gas finally reaching the stomach of the slave-stallion and pumping it out and out as if he had been hooked up to a hose for their pleasure. Arctic tried to moan but so much excrement was being stuffed into his mouth that it was all he could do to keep up, the sensation of it pilling up against his nose and squashing and squelching around his cheeks worse even than letting it go where it was going to be forced anyway.

He'd never known before that there could be so many different layers of submission all piling on top of one another and even clamouring for attention as his belly added another few inches, perfectly smooth as his girth swelled with Luna's gas. There may have been so much broken and churning scat in him that he hardly knew how he was ever going to walk again with all of that forced up inside him but it was the dirty air of her innards that made him feel heavy and weighed-down above all else. His cock ached for release but that was a familiar pain as he was kept on the edge, not expecting any orgasm, anyway, at that time to come with the sense of relief that he truly needed.

Maybe he should have lingered on the bloat of the gas for a little while longer as Luna's guts gurgled, air slipping into solids in the blink of an eye or maybe even the flicker of magic. One moment he was gulping down even more scat from Celestia's behind and the next Luna was emptying her guts into him. The churning grind of more droppings still forced the logs of it deep inside him, turning against reality and how his body should have worked in a way that not even a sex toy could do. One log of shit was forced up against the one that preceded it and a touch of magic too filled him, easing it along, though the insistently tight and painful filling was something that every fibre of his being rebelled against.

Yet there was pleasure there too, like when he was penetrated against his will, each rope of shit teasing up against his prostate. Arctic would have whined if he had the breath in his lungs to do so, yet air was not his to take as he was fed mouthful after mouthful of shit, not even knowing anymore where it came from. Surely Celestia did not have that much inside her? Yet it was not up to him to question the will and being of an alicorn, how Celestia chose to relieve herself, the thought slipping from his mind as he dropped more and more into subspace. It was an acceptance of his fate on new and softening levels, though it did nothing to ease the tension from his body.

Luna's groan reverberated through him as the pressure on his prostate increased, her shit pouring into his stomach, helped along by the parts that were half-solid or even lightly liquid. If it was in his stomach, the smell didn't have to claw at his nostrils, although he knew it was there, more and more gas emanating forth, stinking him up from the inside out. The coil and thickness of her scat pooling inside him was heavier and heavier, though the placement of his body on his back made him feel the whole while as if he was being driven down into the ground, made heavier and weightier with every passing moment.

Arctic tried to roll his head but he was trapped in a world of scat, nothing else existing for him, regardless of the end that was in use. His body was theirs and the thickness of Luna's droppings plopping into him, changing consistency as another meal was released into his backdoor entrance, sent reverberating tremors through his body. The stallion grunted and tried to flex his back end but found himself trapped and pinned in place, cock aching, Luna bringing him over the edge without stopping him from feeling pleasure that time. Yet painting his stomach with his seed felt like a futile kind of victory as it spilt forth, pumping out more and more, his guts aching, pulsing and pounding. It was as if there was something quite alive within him, his stomach rising with more lumps and bulges, body trying to reposition her droppings inside him in a way that would make it easier to bear. Of course, that could have been a side more feasible to do if Celestia was not doing the same thing to him at that very moment.

His belly bulged and strained, though Arctic could not see just how it darkened, the barrier of skin and flesh between his belly and the outside world thinning as his hide strained to hold it all. It was not like air or piss and was something more sordid altogether as his prostate ached, body not knowing which way it wanted to go, what pleasure could be clung to in the heat of such a tenaciously rampant moment. His stomach rolled out hugely, towering higher than even the alicorns, though the slow pumping up of his guts felt like more than it was. His body was allowed to strain and meld around the new shapes and bloats forcing his belly out but it did not know how to hold so much as he wobbled on his back, legs sticking up and out. The swell of his belly forced them apart further and further, even drawing the chains taut, thought the manacles, if left on, would not be the first thing to give out.

With his gut easily large enough to hold several fully-grown ponies inside if such a comparison had been made, he squirmed between the two princesses, his lumpy belly practically groaning as he was blown up more and more. Celestia pulled back off his head for a dose of further humiliation, releasing a steaming load of droppings over his head, splattering his cheeks, his face, leaving him gasping while the stench rose around him. It was fleeting, however, even though he was already amongst so many piles of shit that it was beyond belief, his coat stained and dirty, reeking while he knew not how he was ever going to get the smell out of it.

It hit his head with a pap-pap-pap of sensation, the sound oddly loud even amongst the moans of the alicorns. His wings were spread and dirtied against the ground, his fine, white feathers sullied with excrement, though that in itself should have been the least of his worries. Blinking, Arctic looked down the expanse of his massively bloated stomach, how it rose, blocking Luna from view, though he knew too that she was still there, considering how she was still forcing her droppings into him. The seal, however, was broken around his tail hole and hers and she raised her hips with a groan and a grin, pushing shit out over his nuts, spilling and splattering down his legs and rump too.

Shit flowed over his head, weighing down on his throat, seeping around his neck, leaving him wondering if bondage was necessary at such a moment when he was so trapped. He could have been buried under a pile of shit for their pleasure even if they had had nothing else at all, not even their magic, to hold him down, though Arctic was not about to highlight that to either of them. He couldn't even hear most of what was going on around him even though his head was out of Celestia's tail hole, shuddering and trembling in place, for all the good he could have done for bothering to push away, to fight back. He was there to stay and it was about time he understood that as horse-apples plopped over his head, another steaming pile of shit flowing down his balls as Luna marked him as hers all over again.

He tried to swallow, moistening his mouth with nothing but leftover smears of shit to stain his muzzle, but even that was difficult, his throat sore and raw after being forced to gulp down so much. Yet there was the question as to how much of it was forced upon him when his cock stood up so tall and proud, throbbing obviously, Celestia's tail wafting over it as she tried to see if she could get the flowing wave of it over his colossally towering stomach just for the fun of it.

There was no escaping it, the hot, wet splatters half-solid at times, leaving him simply not quite knowing what to expect at any one time. His tail was soaked and piled up in scat and he didn't even have the will left in him to flick it back and forth, whipping it out of the way, lying there and simply letting it all happen to him at long last. Some small part of his psyche accepted that there was pleasure to be had in there too even if he didn't truly know quite what to do with it or about it. It was not for him to worry about, however, as Celestia ground onto his muzzle, smearing shit into his nose and ears, covering his eyes so that he had to blink it away. No, he was there to be used as the mountains of scat filling the hidden room, the secret of the alicorns, towered around, showing him all that was still yet to come.

Depositing their droppings on top of him had no comparison, to them, as to when it slid down his throat and thickly up into his tail hole. His mane and tail were beyond ruined, shit matting up in the hairs that had, before, been looked after very carefully and well-cared for, though there was still more that could be forced into him, Luna pressing her tail hole back to his and farting deafeningly. The rippling waft of it poured into his grumbling guts but the ropes and coils of thick scat bulging through his colon and intestines all over again had the pressure increasing, once more, tenfold.

However, there were two others interested in his debasement, perhaps even more so than Celestia and Luna...
