The alicorns moved away, over that tank that had an open-top, reeking the most for its openness. It had been one of the most obviously easiest for Nightmare Moon to move, but its purpose became clear as Daybreaker smirked and turned it on, the machinery rumbling to life, the hose twisting and vibrating as it fed pile after pile of scat down it, straight to his mouth.

"Take it all down you, you filthy whore..."

It should have been too far, too crude of a name, and yet that was not the worst of it as he grunted around the tube, thick piles of fresh (kind of), lumpy scat forced into his mouth. With the ring gag in place, he could have potentially not swallowed it down - but where else was it to go if he refused to do the most basic of things in servitude? Their control over him was secure as he grunted and moaned, tongue pushed down to the bottom of his mouth while gross scat poured in.

The thick lumps were the hardest to work down his throat, hating how he was made to swallow. It would almost have been better if a tube was rammed straight down his throat, but the alicorns were most certainly not about making anything at all easy for him. Oh no, they wanted him to feel every sordid, splattering mess as it oozed and squelched into his mouth, squishing around his tongue, filling his mouth with the taste of it so that there was nothing else that he could think of. Right where they wanted him to be, he was forced to gulp it all down even as his stomach bloated out and out, straining obviously through the front of the suit.

Yet Nightmare Moon and Daybreaker showed him quite obviously how they were relieving themselves into the feeding tank that he was hooked up to, even then, giving him more fresh lumps of "horse apples" to take down his throat, scat sloshing about in the piss that was already in his belly, mixing horrendously with the gas there. Yet that would no longer be the dominating featuring of his swollen, pained belly as scat pumped into it, forced down his throat into his stomach where it plopped into the already present mess. He grunted and twisted back and forth to the tiny extent that he was able, though it was his belly and heavy, bloated nuts that were even more effective bondage for him, his body restraining him.

He was there to take everything they had to give, Nightmare Moon and Daybreaker finishing off briefly with the feeder tank taking their waste - but they had more still! It may not have come from their own bodies but the lust in their dominance came from abusing him, and they took turns, one after the other emptying pails, tanks, buckets, barrels - everything they had available to them - into the feeder tank. It rumbled and churned away, pumping everything it was given into the hose, even as Arctic's stomach gurgled ominously, his bladder and bowel feeling very strange. He only caught a glimpse of what was in there, general trash from the palace above, diapers ripped up and stained, even what smelt a bit like compost from the palace gardens... His head swam. How in Equestria had they gotten hold of that? He didn't know what was worse, if anything could be worse than the filth of their bodies, scat smeared, the mess of diapers in their humiliating presentation.

It was not normal, not as his belly bloated more and more, bigger than a beach ball, though that was a comparison that would swiftly go out the window as his size overcame everything that had come before. Arctic struggled, eyes closed, face screwed up, holding back for as long as he could, twisting, grunting, heaving. If he held off as long as he could, maybe that would help, tongue pushing back against the hose in his mouth, trying to stop the filth from working its way down his neck. He could not understand, not even then, the scale of the muck that was due to be forced into him as his stomach gurgled and gurgled, whining through the hoses while his bowels relieved themselves. It was partly his own waste and mostly what had been forced into him, his body confusing what was to go where, piss flowing down his backside while he tried to relieve the strain in his guts.

Until the very last moment, he fought and fought, his guts gurgling, straining, wanting to release everything, pain lancing through. He needed to go, needed to relieve himself, yet he didn't want to humiliate himself further, breath coming in panting, snatched, wide-eyed gasps. But the nightmares before him knew that he would fall, eventually. It was all part of the process for them in abusing him.

"Here it comes!"

They mocked him, emptying two barrels in at once to the feeder tank, forcing more and more down his throat, his nuts aching, churning, every part of him crushed from the inside and the outside. There was simply too much scat to go around, pressing in, the pony messily filling the diaper as a thick slop of messy excrement soaked into the fabric. He whimpered and tried to shrink away, but there was simply no way for his humiliation to not be on full show, not even then, his bowels aching, breaking wind as spattering heaves of scat filled the diaper more and more.

Understanding a little more of what was happening to him, Arctic clamped his mouth down around the gag and tried to push it back with his tongue, to hold his bladder, his bowels, as much as his guts ached and pulsed. It seemed to be coming no matter what resistance he offered, however, his belly bloating, the alicorns feeding more and more mixed waste into him, leading him to wonder, dimly, whether it was from farms and properties around Canterlot too, like what Applejack had once had him do with the septic tank. It was gross, bubbling around his tongue, the insides of his lips, but the steady stream of varying scat and waste, piss swilling through it, the liquid easing the path a little, kept right on coming.

Everything that his bowels blasted out was fed back to him, however, as his cock trembled, too much sensation rendering resistance mute. His dick tried to release too, his body knowing that there was something in there that had to come out, though it was not true seed that poured forth, his bladder weakening, mixing with piss. Arctic howled mutely into the gagging hoses and shook in place, his belly lifting higher than his chin and rising quickly. Soon, it would be difficult to see where the pony lay behind his stomach, slick in the blue latex bondage, his guts merely a vessel for the waste that the alicorns wanted to see him pumped through with.

The suit squeezed the waste from his diaper, as that grew too full, into the hoses connected to his backside, funnelling it to his muzzle as his cock ached and spent a load of filthy piss into the sodden padding. It was overfull and had to go somewhere, Arctic grunting, unable to even tell where each load of scat that was fed down his throat had come from. His neck may have burned sickeningly with the humiliation of messing himself, again and again, and yet that was not the main point of it, old mess mixing with fresh as it was forced through his body.

An unending cycle, a circular system... He might have admired their ingenuity in abusing him, though he was more concerned about the massive tank they were emptying into the feeder tank, messy slop splattering in, a mix that he heaved at the thought of it ending up inside him. He may as well have welcomed it, however, for it was going into him one way or another.

Still, his belly rose and rose, even though his diaper tried to keep up with it. The hoses, however, simply were not enough to keep feeding the excess waste back to his mouth, forcing it into his belly, more going into him as the circular system forced it back round again. He hacked and gulped but the throbbing rise of his belly dominated everything, no matter how his guts churned. Arctic no longer even felt his cock and tail hole relieving themselves, everything funnelling straight through him, though he could only be mildly, faintly grateful that it was mainly liquid that poured from his dick.

Mildly. Faintly. It was overcome by all else.

He bloated and bloated, yet the diaper could only hold so much, covered by the suit as he squirmed in place. It warmed around his body, the roil of waste within forcing it to its limit, yet the compounding diet could only lead one way as he howled brokenly, the diaper finally rupturing, filling the suit with all the waste that it should have held! The latex bulged obscenely, showing his inability to hold his bladder, the alicorns laughing and pointing, his backside rising from the chair as the suit was forced to hold it.

"Look, he's not even any good as a toilet slave anymore!"

"Can't even keep his own waste in... Pathetic!"

They mocked him all in a way that was designed to humiliate him as the suit shifted, trying to accommodate the mess, though gravity helped a little there. Runnier, more liquid waste seeped down his legs, soaking his crotch, a disgusting sensation of wetness overcoming him from all sides. It stained and soaked his fur, turning it from pale to a vile concoction of brown and yellow and grey, old green to soak into his coat later too, though that would only be seen when, once again, he was bare. The suit covered all as he whimpered, filling the inside of his suit, a messy stallion who couldn't control himself, who needed to be controlled.

His suit bulged and bulged, for there was no slowing of the waste that was fed to him, the suit rising more and more. He could barely see anything, head pushing back so that his nose pointed to the ceiling, so far above. Blinking, he tried to focus on that, the stalagmites pointing at him, the crystals so far away, yet it seemed to grow more and more distant before his eyes. Only later would he find that the cavern had been expanding too, the personal effects of the alicorns tucked away in a portal, leaving only them and the waste there to abuse him as they willed.

His gut churned, the pain of it bulging through, lumpy and grotesque, chancing that even the shade of the scat within him could be seen, what with how tightly his skin was stretched along with the suit. That was his imagination at work, however, for he could not see it for himself, even it was true. A steady stream of pissy fluid streamed from his cock as if it could not be stopped, grunting and moaning as the suit billowed out, thicker around his backside yet the weight of it slopping from one side to the other. With the huge strain in the waste from his backside, it could not even be pumped through to his mouth, the suit too giving up in a massive splatter of shit, excrement and piss bursting forth as the alicorns protected themselves.

"Eugh!"

They frowned, shaking their heads, though the relief that Arctic felt was only temporary as they rounded on him, anger flashing. It might have been for show or it may have been genuine, he would never know, as the ruined diaper flopped about, a stinking, massive pile of waste steaming from his backside.

No, they wouldn't have that, not from the toilet slut, no. Grabbing the huge pile of filth, mixed through, and the diaper, they latched onto the two hoses that were now useless, fixing them to another two feeding tanks so that he could still receive a steady stream to his mouth! Of course, there was no diaper for it to instantly slop into as it was forced through his system, pinning another diaper on him as soon as the floor was scooped clean with his magic. Every drop of scat had to go right where it belonged, after all, and they were not accustomed to receiving anything less than everything they demanded.

The bigger tanks rumbled and churned, forcing more and more waste into him as they loaded them up, using their magic to lift tanks that were bigger than they were as more and more containers flooded in. With their magic, they seemed to appear from nowhere, though the alicorns revelled in his filthy debasement as Arctic was forced to take it all, the new diaper filling rapidly as his body simply could neither contain nor control any of it.

All of it. All had to come out, working its way through him, triple-feeding him at his muzzle while his cheeks bulged with waste. The slop of it worming around his tongue was almost expected, though the harder, thicker lumps of it were more difficult to take down, even then. There was nothing else to do, however, for he would not be able to breathe if he did not obey, gulping as rapidly as he could with the sheer volume of waste burned his throat, piss rank in the swill of mess.

Filthy rubber, the remnants of the suit around his hips, clung to his groin, marking the outline of his cock through the diaper, the bulging mess straining through, evident as the white material slowly became darker and darker in shade. It leaked around his legs, though he could not feel it through the all-encompassing wetness, grunting and heaving, eyes half-closed, some primal part of his mind finally submitting, in a raw fashion, to their dirty lusts.

Something crinkled and he started to see another diaper floating before him, disappearing around the grotesque round of his stomach, which would have been able to fill a cave easily by that point, to fit it over the previous one. Whether it was bigger than the other or not was none of his concern, grunting thickly, tongue pressed flat as the hoses suddenly pumped a sickening volume of scat into his mouth. That reeked the worst of all, the rancid stench clawing noxiously at his nostrils, demanding that he pay attention to it, as much as he wanted to ignore it, to forget it to the exclusion of all else.

But he could not ignore it, not as his stomach rose and rose, the second diaper containing what the first could not, billowing out, bloating with the mess. That one too blew out, splattering messily, a third laid over the top, responsible for strapping down the mess and the muck of the slutty stallion bound there. He could not control himself, as much as he, so very weakly, still tried to clamp down, to clench his tail hole, though he should have realised just how far beyond his control that was. His belly filled faster than his anal ring could keep up, bladder and bowels spending the waste, the mess rising in all ways but, of course, faster in his stomach than it was anywhere else. The bloat from his bladder could not even be seen anymore, small and pathetic compared to his heaving, churning, gurgling stomach, the lumpy rise challenging all to push his limits even more.

Leakage spilt forth, staining his legs, though they were already slick and brown. The alicorns scooped up the mess, shoving it back into his mouth via the feeder tanks, the rumbling, groaning machines heated with how hard they had to work to feed him, a scat slave with an insatiable appetite. That diaper too stretched thin, scat bulging through, thick logs of it pushed from his backside, though there was no telling what consistency would bulge from it at any one time, it was just that varied. It leaked and spilt, the floor cleaned once more to not let a drop go to waste, stuffing more and more into his mouth, through the tanks, the hoses trembling as they funnelled more and more.

That, however, could be an endless cycle for the alicorns, and they were not in the keeping of finding themselves bored. The waste in the diapers bulged and strained, kept there seemingly by the grace of a god that was not being kind to him in that moment, huge and bulbous, larger than a carriage - maybe a carriage that would have carried all four of their alicorns at their full sizes. Arctic's head swam. Comparisons were hard, only feeling strain, pressure, slick stench and rancid rumblings...

"You test us, slave pony."

He did not mean to, not even as they removed the diapers, relieving him of the strain, at least in one way, a new latex suit going over the top of everything in the same shade though, of course, leaving everything contained. A plug rammed up his tail hole with a burst of pain that had his eyes rolling, no consent given, not even then, for such a crude action. Arctic howled brokenly, though the sound would never reach the ears of Nightmare Moon and Daybreaker, not as they shoved everything into the tanks, fixing the new hoses to the mask.

Of course, what they did ensure remained in place was a fresh diaper, thickly padded and humiliating as if he needed it, as if he really could not control himself. Even with the latex suit in place, the slick blue covering him, soon to become as filthy as the pony bound in it, it crinkled and rustled, reminding him of his place. Arctic trembled. The option of choice had been taken from him, just as was right.

"Now... We'll see how big you can really become!"

They laughed, the new latex suit a thicker layer still of heavy rubber, more and more manacles going around his arms and legs, holding him in place while allowing his gut to bulge. It swelled heavily over the arms, no longer a smooth-ish round but weighed down by itself, scat churning and swelling inside, pushing for precedence over the mess of all the other waste locked up in there. His belly even lay on the floor as he wriggled there, pinned by his own stomach, panting and heaving, though they would take him elsewhere once he was too large for even that. Of course, they still wanted access to every part of him as they sat on top of the tanks that they fed, using their magic to levitate more and more into them, feeding his mouth.

However...it was not all clean waste, the kind of waste that he was used to, that was stuffed into the tanks, forced into the hoses. The billowing, heady swell of his stomach, only ever so slightly depleted by what they'd managed to force out through his bladder and bowels, bulged out grotesquely, more and more, forcing them to levitate the chair, his bondage intact while their fizzing, crackling magic bound him in chains stronger than any metal. Yet they wanted him to feel trapped, even as his stomach rounded more and more, gurgling with scat, the diapers and trash and other waste that filled other tanks and barrels all very suitable for shoving into the scat slut's throat.

More and more filled it, the alicorns relieving their bowels and bladders too into the feeder tanks, as they had before, though it was not enough alone to bloat him up. The suit swelled to accommodate the bulge of his belly, infused with magic, yet he did not feel at all like he was floating in the air, his stomach dominating, filling the cavern.

He was huge, grossly so, his nuts bulging through the latex, an afterthought to the heaving roil of his stomach. He'd far surpassed what had been their original living quarters, back when he had first met the evil queens, but the cavern seemed to grow around him, allowing him to expand more and more, delirious, his cock aching, throbbing, though it was merely the broken remnants of orgasm that pulsed through him. Maybe it could have been pleasure, at one time, but it was impossible to consider it such when his body was tiny, dwarfed by the heaving monstrosity of his filthy, scat-filled stomach.

There seemed to be no end to the tanks, but, alas, the alicorns were so apt to grow bored with him when their appetites were not sated justly. They needed more, to take him, to abuse him, the hoses adjusted so that the thick, central one was replaced by another that had been set up ready to go, three hoses still and two rammed in the sides of his mouth. That hose was already fastened to a giant tank that appeared as if it had, previously, been at the back of the cell before the cavern had expanded, their magic making it so that he could take everything and more while his belly bloated and gurgled ominously.

Arctic may not have known, but that tank, fed by two hoses, disappearing up and up and up into the darkness, fed the waste from Celestia and Luna's private chambers, respectively - a few more plumbing changes for the alicorns to claim fame too! All he felt, however, was the thick mass of waste pouring into him, a sloppy sludge that felt, to him, as if it had been sitting there for weeks already, maybe even longer, the latrines well-used and the system overflowing with all that had been poured into it.

He was dimly aware of them adding more to the feeder tanks, though those seemed to be further away from him still as scat pressed out through his belly in thick logs, the latex strained. It was stretched so tightly that the shading of scat, piss and filth through it made it look dirty, even if the outside was clean, filth squirting and oozing around the plug. That was just a tiny flicker of the pressure being released, however, for his tail hole instinctively clamped back down around it as his nuts churned, cock throbbing, the stark outline of it massaged cruelly by Nightmare Moon through the suit. That too had been stopped up with a long sounding rod that fed right the way down into his nuts, though he had not realised, only felt his nuts churning, trembling with the need to spill both a load of cum that had built back up in there and all the scat that he had been filled with too. Plugged where they didn't want his waste to come from... His head pounded, the pony groaning. It was fitting, as disgusting as it was. If only it didn't make his cock so hard.

"I thought you must have missed the princesses and their filth," Daybreaker hissed, sparing a moment to croon, cradling his head, his stomach hanging and bloating, thankfully, away from his face while he was suspended and allowed to grow in tight restriction. "So dirty... No one but us knows what goes on behind closed doors with them."

All their waste too, all of it... He drifted in and out of reality, three tanks fed to him, swallowing the whole time. As much as the thick lumps of filth stuck in his throat, there was a part of him that was dimly aware that he should have been honoured, to know that he was serving them, satisfying them, playing his part as their toilet slave, regardless of their penchant for humiliating him in filth. His stomach ached fiercely, though it was the strain and pain of being overfilled, the cavern roof appearing closer to him than before. The massive cavern had, previously, stretched out and out, though their original cell had merely been a ruse, something else to twist his sense of reality as they teleported him to another part of their messy, sordid chambers for his abuse.

Arctic didn't need to know that. All he knew was that there was a diaper thick in his throat, ragged and torn, forcing him to choke it down as he gulped down more and more. It was a never-ending stream of waste, always more, nothing to stop it, months and months of the princess alicorns' waste pumping down his throat amongst all that the queens stuffed him with. For they were evil queens, it had to be said, furious to debase him, the machinery emptying everything into his muzzle, pump after watery pump.

He didn't know how long it took until the machines were empty, only that his head pounded, drifting back and forth, swimming in lustful debasement, submissiveness dragging him down. Their wings and magic kept them aloft around him, though the alicorns merely walked on "air" as if it was the ground, their tits huge and heaving, teasing them against his muzzle.

"Shame that you can't drink straight from the source..."

No, they would not do that, not bearing him the sweetness of that, instead milking their tits into one of the feeders, allowing that to rumble and force the milk to his lips through a sludgy, remaining layer of scat and waste. It tainted the cream from their breasts and yet he still had to gulp it all down, the lump in his throat larger and harder to push by than ever.

It should have been a treat...but it wasn't. Their milk was another nuance of abuse, something to remind him of what he could have had, if he was the sort of pony to match up to mares of their stature. But that wasn't what they wanted when they could make his belly churn even more vehemently with their milk and scat mixed, slickening and slopping in a watery haze down his throat as he kept right on swallowing and swallowing.

There was just the one diaper left on him, though it was anything but clean, under the bottom layer of latex, though even the torn edges of the original suit clumped and clung uncomfortably to him. His bloated bladder pressed into the waistline of it, cock wanting to relieve even more, though his body did not know whether it was urine or seed that it needed to spend, compounding the problem for him.

Huge. Suspended. The body that was him no longer seemed to be part of him, only the belly, bloated, a huge, lumpy round that took up near the entire cavern. If he had been in Ponyville, he would have flattened several clearings with his size alone, though the alicorns giggled, darting around him, cruel mischief in their tone. The diaper crinkled, though the rustle of the cloth could not be heard through the suit, even if he could feel it. He felt everything, moaning, everything tight, so very tight, his throat working and working to take that whole revolting mess down his throat, right where it belonged.

"Do you think he can go even bigger than this?"

Of course, they were keen to see, though they did not give him that treat from their breasts. In fact, he didn't even get to taste their milk as they alternately used their hands and their magic to milk their breasts, creamy rivulets of milk flowing into the feeding tanks. Sometimes, their magic kept it together, allowing him to feel something warmer flowing down his throat, even if he could not taste it, though most was mixed in with the filth and the waste, the slut pony not even good enough to warrant a taste.

No... Not a toilet stallion, a filth slut. It was only for them, just for them, and they revelled in his debasement far too much for that. Arctic whimpered, only half with reality, the alicorns pumping an increasing amount of breast milk into the tanks, his stomach coming up onto the size of the cavern again.

Too much, he was too big... The alicorns did not look small, per se, but they seemed far away to him sometimes, his belly cramming against the cavern wall. He could have flattened at least nine clearings as his stomach swelled and gurgled, the milk mixing viciously with the waste inside him as it churned violently. The gas produced increased the strain, smoothing out his stomach as it filled in the lumpy, scat-ridden gaps, yet it did not help anything, his belly huge even as somepony, somepony who very truly might have been able to help him, entered the room.

With his fur covered in filth, clumps of scat sunk into it, sodden with piss, gurgling with so much waste that his body was no longer his own, Princess Celestia and Luna bore witness to him, the only slave pony in Equestria who could satisfy the lusts of the nightmares. He saw them, the glows of their bodies, but could not even feel shame for his condition, his stomach dominating all. Did his mind matter when what was left of his body was merely attached to that hugely bulbous belly? The cavern grew larger again, within the bounds of, presumably, what the alicorns were permitted to excavate beneath the castle, allowing him more room to grow, even as his backside pressed down heavily into the ground.

"I..."

Lost for words, Celestia shook her head. Luna frowned, but was hardly more eloquent than her, though she did lead the way by shifting to her anthro form. The diapered pony sagged back from the bonds of his bloated belly, the blue of the suit filling the cavern, so huge that one had to turn their head back and forth and up and down simply to get some small idea of the huge scope of it. His diapered backside sagged with filth, anal ring tightening around the plug, though the mess shoved up in there had been all by their design, his body made to be disgustingly used at all times.

"You..." Celestia joined Luna, though her shock could not be hidden so. "You took this from our private chambers? The pipes don't even reach that far!"

"Oh, relax, Tia, where's your sense of fun?"

Squatting over the feeder tank, Daybreaker winked and sent another load of excrement into the tank, piss washing it down the pipe, right into the pony's belly where it belonged. But she approved of being on display too much to spend more time on words, offering only another hose to truly debase the pony, one that linked up to the tanks that were, quite obviously, painted with the cutie marks of the princesses.

That hose locked onto his backside, though not into his tail hole. He felt the tug and the push of it, though anything they filled him with there would not match his belly by a long shot, not unless they kept him there for hours upon hours, used and abused, filth pumped from the princesses into his diapered backside. It squelched crudely through the padding as he gulped, unable to even whimper, muck squishing around his backside, soaking even more powerfully into his fur, the reek clinging to him. Even through the suit he could smell it, burning his nostrils, fed so much scat that he doubted he'd ever be able to taste anything ever again, the latex stretching and stretching to accommodate the lumpy, bulging diaper.

He was huge and their shock, to be fair, could not be long-lived as his diaper inflated with filth, to the point that he would not have been able to waddle with it on, even if his belly had not been so huge. The rubber stretched and stretched, Luna rocking back as it bloated out, though a little magical reinforcement helped keep it in place. The muck, however, could not help but squash and ooze around his nuts as he was filled, Celestia smirking ever so faintly, rubbing her hoof against her muzzle.

"I think there's a part of him that you missed..."

She could see what they had missed, as grotesquely bloated as Arctic was, magicking in a new tank of fresh waste as Daybreaker raised her eyebrows.

"You missed what the party guests deposited," she said with a wink and a rather evil grin. "This will fit in those nuts of his quite nicely."

With his diaper swollen with filth and the suit bulging, it was set to be challenged more as a little magic helped fix a hose into the diaper itself and lock around the head of his cock. It may not have been comfortable as it locked into place but the filth squelching into his dick, worming its way down his length in fat, penetrating logs, could not be held back. No part of Arctic's body was not left strained, bulging, squeezing out more and more into him, his nuts aching. He didn't know where that filth was coming from, his diaper overfilled, his balls fit to burst - though that would never happen. No... Oh no. That was not the way of it as his body was forced through more and more humiliating acts, straining and stretching to contain everything dirty, everything that a slave pony toilet like him deserved.

Crrreeeaaak!

_ _

The suit strained, his lumpy balls bulging, everything bulging. There was no shape left to him anymore, Celestia shaking her head even as she shook her finger at the alicorns, though they were not to be swayed by her scolding.

"Our waste should never be used in this manner..."

"You aren't being all that convincing there, Celestia." Nightmare Moon scoffed. "Maybe if you hadn't hooked the filth slut up yourself..."

Yet it was all in their fun, a good kind of fun, Arctic moaning, eyes half-closed. Thickness pushed through him, his throat forced to bulge around even nastier logs of filth, fresh waste mixing with old as it cloyed its way down his throat, his tail hole squeezing around the plug, his body fighting to force it out.

"That's why we're feeding him fresh from the source instead..."

He tried to turn his head, but all he felt was the wrap of firm magic around him, Luna's blue glow encasing him lightly, gently. Yet the muzzle and hoses being removed from his face did not offer him any respite as he caught her smirk, his vision suddenly filled by the round moon of her backside, her tail hole grinding into his mouth.

Thus, he was forced to gulp down her waste too from her very own backside, so broken that he could not even resist, trapped in the bondage of his own inflated, scat-filled stomach. He swallowed and whimpered, throat raw and burning, though the thick flow kept on coming. Only vaguely was he aware of his cock being drawn out, the hose filtering, only a short length, to Celestia's backside, the nightmares laughing raucously as the princesses themselves fed and filled him with their scat.

His dick ached and throbbed, but Celestia's waste was going down his cock, filtering into his nuts, which swelled and swelled, gurgling and rumbling. Even with no available space in his nuts, they still tried to make more cum, his length pulsing in faux orgasm, even though there was nothing to come out, no way that a pony like him could experience true, euphoric pleasure from an act like that.

They'd made sure any orgasm would leave him strained, so that it didn't even feel like an orgasm at all. All he was proved to be a vessel, a toilet, stained and reeking of scat, taking more down his throat, even then, as Princess Luna giggled and held a hoof to her lips.

"Seems I had a little more in me than expected..."

He could not complain. The stallion did not have it in him to complain. Not even as a particularly thick log followed a pile of round droppings from Celestia, squishing their way down his cock, the log forcing them there as the tight passage inside his length was forced to thicken and widen for it. She moaned out loud, relieving herself openly, but Arctic was not even present in that moment, feeling only, yes, only feeling.

There was nothing else for him, drifting and fading, some part of him luxuriating in the dirty abuse, even though it was not something that he would admit out loud.

The last thing he remembered before passing out was appearing in the woods being Mistress Shy's cottage - at least, that was where he thought he was. It was strange to see it from so high in the air, his wings hanging weakly, balanced on the grotesque rise of his stomach, trees pricking into it, though he flattened them easily.

So big... How much space did he take up? The cottage would not have been large enough to match the size, as petite as it was, of his testicles, leaving the bulging mass of his belly enough to crush at least half of Ponyville. He swayed on the bulge of his stomach, a diaper plugging his muzzle full, though the squeeze of scat oozing around it was not to be denied.

Dimly, he was aware of Mistress Shy flapping around him, a high-pitched whinny bursting from her lips.

"What have they done to my pet?!"

But it was only what she had agreed, even if more than intended. Her pet was there, the huge, overfilled diaper sagging behind him, filthy and disgusting, though there was more to his use and abuse than even she had realised he could take. Despite her revulsion, holding her hoof over her nose, Fluttershy surveyed him with the calculating eyes of a mistress who had realised a little more about their pony pet than had before been in play.

Their magic kept him safe, but there was only so much that a toilet pony could take, slipping into unconsciousness while his mistress screamed for her friend, Twilight. Ponyville would reel in horror from the scat-filled disgust of his body while the scat pony revelled, in some deep, dark way, loving the filth when he was not permitted to like such a thing openly.

"Interesting... Ugh, you reek!"

Thick, inflated, as he was meant to be. Even in unconsciousness, his lips shifted around the diaper-gag in a weak smile. Fluttershy shook her head. Her toilet pony had more for her... More ways to abuse him, to break him down into her submissive pet, always and forever.

Submission was one thing. But there was always a way to take it deeper.

Always.
