Celestia and Luna get trained and used as toilets after a failed diplomatic mission to Yakyakistan

Celestia and Luna's diplomatic mission to Yakyakistan did not go to plan. They wake up bound in the dark without their magic, and from there things only get worse as they are used and trained into toilets by the Yaks.

Chapter 1

Yakyakistan was a strange place with strange customs. It was understandable, as without the ideals of friendship and the powerful magics that kept the pony kingdom running like a well oiled machine, the world was an extremely harsh place in which to live.

And the Yaks, to their credit, had adapted well to it. They had become tough warriors and powerful within their own right, even without the magical powers that the ponies took for granted.

That was why Princess Celestia had been sure that the diplomacy mission was going to go well. She and her sister provided the moon and the sun to the yaks, and they were offering them safety and security in return for an alliance. It was meant to be a simple trade.

The yaks had taken it to be an insult that she had bought guards along with her however. She had no idea why that was the case, but the guards either side of her head been knocked out, and then before she had been able to react, she had been forced to follow along with being knocked out cold.

She awoke with a splitting headache in the dark, having no idea what it was that was currently happening as she was not able to see. Her first instinct after realizing this was to light up her horn in an attempt at lighting up the toilet around her, but for some reason her magic wasnâ€™t working, and all attempting to use it did was send a jolt of pain through her.

Her magic was bound, she was sure of that now, and it only slightly intensified her panic as she begin to struggle. Her hooves were bound behind her back, and it felt like her mouth was being pried open as well. She just needed some light and some time to think her way out of this situation.

Had the Yaks done this? But why? And to what end? The pure white alicorn had been alive for thousands of years and yet she had never seen a diplomacy mission fail quite this hard before. Was it something she had done? Something she had said?

She did not know, but she begin to struggle roughly against her binds, giving a soft growl as a sense of rage swelled up inside her, burning brightly before she managed to repress it.

Across from her, she heard her sister make a muffled noise. She would recognise her sister from anywhere, and she desperately wanted to see if she was OK. She was starting to get seriously worried that something had happened to her. Thankfully she did not have to wait long to see the terrible state of affairs that she was currently in.

A beam of light came in from above, with a circle shaped hole that sent beams of white light shining down from above. Celestia was bound, just as she had expected, but she had no idea where she currently was. It looked like some kind of pit, but she could not be sure.

She stared up at the circle of light from above, but it was quickly blocked out by something she did not manage to look at, at least until a musty light bulb managed to flicker to life over head, weakly working to fill the small room within which they were bound with a sickly yellow light.

It was a small wooden box that they were confined in, and above was the rear end of an absolutely huge Yak. She almost vomited in response to the situation as she took in the next few details of their situation. The Yak was sat in what appeared to be in a toilet, with a clear plastic toilet bowl, and leading from said toilet bowl was a clear rubber tube that connected straight to her sisterâ€™s mouth after about eight foot of pipe.

Her sister was wearing a metal ring gag through which the tube had been forced, and she was bound within a device that looked much like an old stockade from back when Equestrian used such brutish punishment methods.

And she was bound in a similar situation, only her hooves were spread apart with a spreader bar. She had failed to notice because there was a harness holding her up and reducing the weight on her joints.

Normally Celestia was not one for cursing, but at the moment a number of the most profane curses time had ever seen were tearing their way through her mind. The massive backside of the Yak firmly seated itself in the toilet, and somehow she was able to take in every detail as their massive puffy anus slowly spread with the sound of foul gases reverberating so loudly that she was able to hear it from even down in the pit where she was currently bound.

A thick brown log of yak shit begin to force its way from out of the yakâ€™s rear, spreading itâ€™s ass wide as it let out a soft, satisfied sounding grumble and tensed its anus hard, forcing even more of the massive log from out of its rear, where it touched down against the toilet bowl, the Yakâ€™s anus tensing to cut off the massive log.

Unfortunately, it was not done yet, and with another soft grumble, the Yak begin to squeeze a second log from out of its rear, Celestia wanted to look away, but she was transfixed in horror at the scene unfolding before her, the second log joining the first as the Yak gave a soft sigh and then a stream of golden yellow fluid joined the logs of waste in the toilet bowl.

The Yak didnâ€™t bother standing up to urinate, its member somehow managing to get every single drop in the toilet bowl without the slightest of issues. Things only got worse from here, as the Yak stood up from the toilet and pressed a button.

A loud hiss filled the air, and some kind of magic forced the massive logs of shit down the rubber tube without the slightest issue, forming into a foul slurry with the urine that had been mixed with it, and all of it was currently flowing down the tube to the maw of her sister who was currently on the other end of the tube.

The poor mare could do nothing but scream as the foul fluid flowed down the tube. Right now Celestia wanted to turn her head away and focus on anything but the scene unfolding in front of her, but it was not possible to do so due to the way she was restrained. Luna was forced to stare up at the toilet bowl above and wait for the next load of vile substances to be forced down the tube.

Luna was not able to form proper words due to the gag, but she was certainly able to show how unhappy was with the loud series of screams and pleas she tried to force through the gag upon seeing the torture that she was about to endure.

She would never forget the squeal her sister let out as the foul substance finally reached her lips and slid into her mouth. Her eyes rolled back in her head and for several moments her throat convulsed so roughly it prevented the thick load of shit from going down her throat.

And then her throat convulsed again, vomit suddenly forcing the shit from out of her mouth and back up the tube, Celestia able to see the sickly yellow bile mixed with the remains of her last meal as it tried to push the shit slurry up and away from her maw.

Unfortunately, whatever magical spell they had to force the scat down the tube was not going to give up that easily, and the thick slurry of shit suddenly pushed downwards, and now her sister was forced to swallow her own vomit on top of the massive load of Yak waste.

Luna was sobbing at this point, tears streaming down her cheeks as she desperately tried to break her bindings, but as Celestia had already found out, the bindings were almost impossible to break, and along with that their horns were bound so magic was off the table.

Celestia felt her heart break, tears starting to drip down her cheeks as she tugged against her own bindings, desperately wanting to help her sister, but not able to do anything. She felt totally helpless, but on top of that, she felt angry. A deep rage unlike anything she had ever felt before suddenly flared up within her.

Her frame was large, and although she had spent most of her life eating cake and living a life of luxury, she was far from weak, and more then able to take care of herself if it came to it. Steel chains should have been no trouble at all for her to break, and yet that was not possible for her to do.

Whatever these chains were, it was a lot more difficult to break then simple steel, maybe they had been toughed up somehow. Luna was making a series of terrible retching noises as the thick substances were forced down her throat, making her wretch even more.

This carried on, Luna would force it back out of her body, and then it would be forced back down into her mouth, only for her to fail to swallow it again. And while this was happening, Celestia got a nasty shock of her own, as there was a door down in the pit that suddenly swung open, and two Yakâ€™s walked into the room.

Almost instantly Celestia begin to cry out into her gag, desperately attempting to beg them for help, although she knew it was likely pointless, the fact her younger sister was in danger made her ignore all of that.

The yaks were talking to her, and she should have likely paid far more attention to what was being said, but at the moment her head was tearing itself apart, and she simply wanted help, nothing else mattered.

The tube was pulled from out of her own mouth, and for a moment hope blossomed within her chest. And then a moment later it was crushed in the cruellest way imaginable. In fact, all of this was beyond her imagination, and beyond the imagination of all but the most unhinged of ponies.

The larger Yak, who she did not even get a proper look at, suddenly turned around and presented his anus to her, still crusted in scat and shit, along with other foul substances that she was not able to identify. She actually lost a few seconds of memory as her brain totally flipped out and she tried her best to scream.

â€œPony lick!â€� The Yak said firmly. Celestia totally ignored him, trying her best to turn herself away so she did not have to look at the shit smeared hole. The yak showed off that classic lack of patience when just a few seconds later he pressed his ass back roughly and rubbed his anus against her face, smearing shit over her lips and nostrils, which instantly begin to drink in the foul stench.

She was crying again, her nostrils felt like they were burning, and she was sobbing softly as she tried desperately to pull away, but it was all hopeless, there was no getting away from this nightmare.

Her sinuses felt like they were on fire, tears were streaming down her cheeks, and right now she wanted nothing more then for this to end. But unfortunately it was not like most nightmares, because this was not something that she would be able to wake up from. She was trapped here, there was no escaping the seemingly endless torture, and the assault on her mind and body from the thick scent of the Yak scat.

Some of it was still up her nose, and she had no way to get rid of it, meaning her nose was now constantly being burned and assaulted by the constant overwhelming scent.
More sobbing tore from her lips and into the anus of the massive sweaty Yak, who was pressing his rear back against her roughly with a series of soft satisfied grunts and groans, smearing all the shit that coated his rear onto her face, before pulling his sweaty rear away.

Tears were still rolling down her cheeks, but the second Yak moved up and pressed something into her mouth, forcing it passed the gag before slotting her tube back into place, cutting off any attempts at pleas or begging.

She did not see what the Yak had forced into her mouth, but it seemed to be a pill of some kind. Celestia was angry, and her stomach turned rather suddenly, attempting to empty her stomach and get rid of the foul scent and substance.

Her eyes rolled back in her head slightly, and a thick stream of burning bile that tasted terrible suddenly forced up from the back of her throat, washing the pill away and forcing it up the tube.

She knew what was going to happen next, and she was totally helpless to stop it. The magic spell on the tube forced the vomit back down her throat, and she let out another broken sob as the vomit was forced down her throat, along with the pill within it.

What had she done to deserve this? The question kept playing in her head as the pill slid down her throat, and it did not take long for its effects to become apparent. Rather suddenly she felt like she was disconnected from her body, watching as the Yak moved over to her sister and forced the same purple pill down her throat.

Her whole body felt like it was miles away from her at the moment, she wasnâ€™t Celestia, Royal Princess of Equestria, she was just a third party watching from somewhere else as a Yak moved up behind Celestia and teased gently against her snatch with one of his cloven limbs.

The pleasure that this sent spiking through her body almost made her eyes roll back, legs shaking softly as she worked to press back against their touch. She should have hated it, if the part of her brain that controlled her sense of self was actually functioning at the moment, but unfortunately for her, it wasnâ€™t.

The only thing she did know was that it felt good when the Yak pressed his cloven hoof against her cunt. And she liked feeling good, so she wanted more of it. She desperately ground her snatch back against him with a series of soft, needy whines that certainly did not suit the princess of Equestria.

Not that it mattered, she was not really a Princess any more. Nobody knew where she had gone, apart from the guards that had been with her, and who knows where they had ended up.

But before she was able to reach an earth shattering climax, the cloven hoof was cruelly pulled away from her snatch, leaving her to give an animalistic whine in a desperate attempt to get the Yak to make her feel good again.

Her entire body felt hot and heavy, her muscles felt weak and unresponsive to her attempt to get them to move. Above her, a rear of a rather small yak suddenly took a seat over the toilet. A large load of shit was soon on its way down the tube towards her waiting maw, and normally she would have vomited, struggled or thrown a fit upon seeing it flowing down towards her.

At the moment she simply didnâ€™t care in the slightest, the thick load of shit soon touched down against her lips, and she did not even wretch in the slightest.

She could tell it was bad, she could tell she wanted to spit it out, but it wasnâ€™t sending her into the same blind panic that it would normally have.
â€œPony swallow and Yak make stupid pony princess feel good.â€�
She didnâ€™t think she liked being insulted in such a fashion, but it sounded like a fair trade to her, and she pulled her head back and begin to swallow down the thick load of shit, her eyes rolling back dopilyy in her head as the Yak let out a soft grumble and begin to rub at her snatch with that hoof. He groaned in pleasure and arched her back roughly.

The thick, warm slurry of foul tasting fluids flowed down her throat easily as she groaned in pleasure. An orgasm suddenly ripped through her. She cried out into the gag and almost choked on the thick load of shit sliding down into her belly, which didnâ€™t seem very happy about having shit rammed into it.

Her belly retorted with a loud rumble that she barely even noticed as she desperately pressed back against their cloven hoof, groaning and whimpering loudly as she tried her best to get the Yak to give her more pleasure.

It did not exactly work out for her, as the Yak was already walking away, leaving her alone in the dark toilet pit.

The next few days proceeded, there was a lot more drugs and a lot more shit to eat, and to Celestia they passed in a blur, barely even noticing the existence of her suffering, and only really caring in the slightest about her next drugging and the next series of orgasms that she was going to earn.

When the drugs did finally get chance to wear off, Celestia found herself coated in a mixture of shit and urine, filling the air with a foul stench that had soiled her coat and drenched nearly every inch of her body.

Celestia didn't let any of this break her spirit however, even in the face of such terrible odds she held onto hope. She had lived for thousands of years after all, and she had been through far rougher times then this.

She had seen and lived through hell, and she had endured to the very best of her ability, this was nothing new, and between her drugged up trances, she was plotting an escape, she was planning to break out of here and return to her kingdom, then she would get revenge on the Yaks who had allowed such horrible things to happen to her.

That spark of hope, that spark of defence, could carry her through anything!

Luna, meanwhile, had already given up. Her sister had trapped her for a thousand years on the moon, and the ponies did not really care for her in the slightest. They would happily leave her out here as little more then another forgotten relic, and while she would have liked to have had some shred of hope for her sister, it was her who had gotten them into this situation in the first place! It was unacceptable, and it was hopeless.

She certainly didn't enjoy her new life, but at least the Yak's had the decency to give her drugs that made her feel good between the rounds of torture that she underwent. That was more then her sister had ever done, and while she was trying her best to stay calm, the old hate for the way in which her sister had treated her was flaring back up.

Time lost all meaning to the two sisters, passing in a blur of drugs and shit slurries that their stomachs eventually got used to. Celestia's willpower showed cracks, but never got weakened beyond that. She was as unyielding and unbending as the sun she commanded, a sun which was currently drifting along unaided by her.

The magic bindings were an issue, the fact she couldn't summon up even the most basic of spells was certainly trouble for her escape plan, but her mind was as sharp as ever, when it wasn't drugged up. Or when she wasn't horny. Or when she was eating shit.

She was just now realizing that it was actually a lot of the time that her brain was not working properly, not that it mattered, she still had plenty of time to figure out a way to escape, and the perfect opportunity came when one of the Yak's entered the room and put a gold collar around her neck, and a blackened steel one around that of her sister, releasing them from their bindings and slowly escorting them from the room.

This was her chance, this was the perfect time for her to make her escape! Her mind was racing a hundred miles a minute, and yet with her loins burning like they were, not much of that was going towards anything useful.

She wanted to get this heat out of her loins more then anything, to have one of the Yak's rub at the burning, aching place between her legs until the thick fog was lifted from her mind and she was able to escape.

Unfortunately that was not possible, and her mind should have instead spent that time worrying about where it was that they were going, as things were about to get even worse then they already had been for the two sisters.

For the first time in what felt like forever, Celestia was bought outside. It was mid-day. Celestia's connection to the sun could not be broken completely without killing her, and therefore she always knew what time it was if she focused enough, but feeling the sun's warmth shine down on her, it helped to lift the fog from her mind just a little.

All she needed was to get this horn binder off and she would be able to use the power of the sun mixed with her own magic to burn everything in sight without the slightest of issues. It wouldn't be a problem in the slightest with how powerful she was, and how angry she currently felt towards her captors.

They didn't deserve the slightest hint of mercy, and she would be sure to not grant them any as she burned them to ash.

There were other creatures here! Other creatures going about their day to day lives like nothing had changed, griffons and zebras, and... And none of them had bothered to help in the slightest, in fact they actually seemed to be supporting the horrible things that had happened to her, clapping and cheering as she was paraded down the street.

The worst part was, if it weren't for the ring gag she would have tried calling out for help. She was still coated in shit and other foul substances that she could not even name at this point, the stench coming off her own body was unreal and she would have done anything for something as simple as a shower!

She didn't think it was asking for too much. Celestia, Goddess of the sun, and the most powerful creature in all of Equestria wanted to cry.

In the middle of town, a set of metal stockades had been set up, with the cutiemarks of her sister and herself carved into them, along with other things set up that she didn't even know how to begin identifying.

Celestia and Luna were bound into the stockades and consigned to their fate. At this point there was very little she could do. A crowd of different creatures formed around the stockades, and some of them happened to be holding ponies, ponies on the ends of leashes, ponies that looked like their spirits had been shattered.

How long had Luna and herself been gone? She wanted to get angry, she wanted to break the Stockade and put the fear of a goddess into these damn fools, but that thick fog was still hanging over her mind, and about the only thing she was able to focus on was the fact her loins felt like they were on fire.

"The two princesses of Equestria, supposed Goddesses that came crawling to us on a mission of diplomacy, foolishly dooming their own country in the process!" A zebra stallion in a wine red overcoat declared.

"Today, they will be starting to make up for their failings by serving as public toilets! Form an orderly line and use them to your hearts content. Buckets are provided, or you can force feed them directly from the source."

Celestia thought about just how easily she could reduce him to ash if she managed to get her horn binder off, wondering if his smugness would hold up when every atom of his body was on fire.

Such thoughts were soon brushed away by the events unfolding in front of her however, several of the bolder creatures had already stepped up onto the stage, a zebra using a bucket to relieve himself into, while one of the bolder diamond dogs stepped up and took his member in one hand.

The strange pointed member was hard with excitement from her suffering, and a stream of dark yellow fluid that stank of musk soon begin to pour from it, splattering onto her face warmly and forcing her to close her eyes.

Some of it had landed in them, and it burned. Celestia had talked about how she would never bend or break, but if what they were saying about her kingdom was true, then she had failed her people.

They were suffering because of her! Because of her failings, and she did not think she would ever be able to forgive herself for that.

The Zebra stallion stepped up next to her with the first bucket once the diamond dog was done drenching her face in his warm fluids, apparently having been aiming for her mouth and nose.

"Now, if you gargle this shit like a good little mare, I think I might help you with your little problem back there, does that sound good to you, toilet?"

Without waiting for a response, he tilted her head back and pressed the bucket to her ring gag, tilting it backwards until a watery shit slurry poured from out of it and entered her maw.

She gagged almost instantly upon it touching her mouth, but the zebra didn't let up until he had filled up her mouth, at which point he covered the ring gag up with a hoof, forcing her to swallow or attempt to gargle it.

What happened was much worse. Her body was attempting to get rid of the foul substance, but with her mouth covered, the only exit it could take was out her nose.

Celestia suddenly convulsed wildly as part of the shit slurry spilled from out of her nose, making her gag loudly as the zebra stallion jumped back with a soft laugh, watching as she contorted and gagged with her eyes rolling back and her entire repository system feeling like it was on fire.

Her eyes were bloodshot, her nose burned, pretty much every ounce of her body was in some amount of pain, and the stallion just laughed like it was the funniest thing that he had ever seen, like her suffering meant absolutely nothing to her.

He didn't even bother to satisfy her heat. The buckets got filled up and dumped over the two sisters, over and over until every inch of them was coated in shit and hurt or itched due to the foul substances coating them.
Celestia held strong, but her sister broke like a twig under all the pressure, her eyes becoming vacant and glassy as she obediently licked at the anus of any creature that wanted it. It was watching her sister bury her nose in the anus of a griffon, licking every ounce of shit from it, and then thanking him, that finally broke Celestia.

Her sister didn't even need the ring gag any more. She spent half the day hoping it was some kind of trick, that her sister was simply doing it to fool them. But that was not the case, and the zebra stallion who had organized this whole thing stepped over to Luna and force fed her the same sloppy mixture that Celestia had been fed.

Her sister gargled it. She tilted her head back and rolled the foul slurry of digested food around her tongue like it was some kind of delicious treat, making her cunt gush until a griffon stallion gifted her with an orgasm, at which point she begged to be fed again.

Celestia's mind couldn't take it, and it shattered apart as she finally accepted her fate, finally accepted that there was no way out of this situation.

And so it was that the two royal sisters fell, minds shattered, now little more then glorified toilets for whatever creatures wanted to use them.
