From Princess to Privy (scat)

"Noooooohohooo!" Celestia cried out loudly, still overwhelmed by the unholy experience of the intense smell and the beyond horrible taste of her new owner's farts combined with the sour urine trickling down her once white, royal fur.

That was not why she was crying this desperately, however. That was owed to the fact that she was about to experience something far, far nastier...

Compared to what the Queen had planned for her, the previous torture had merely been a warm-up. Like pulling out a few teeth of the victim before giving them the knee-splitter, or perhaps like whipping them a while, before putting them on the rack... For Celestia... This was her rack.

The play session was over. Celestia had been deemed to be sufficiently warmed up. The harsher torture could finally start. She was about to truly suffer. It would not be painful, but it might as well have been, for defilement of this caliber could barely be rivaled by any form of classical torture. For a princess, there was no worse fate. For there was no deeper fall from glory, than going from goddess to sceptic tank.

...

She was wailing and screaming like a desperate child because she knew she was about to be force-fed Queen Chrysalis' literal fecal matter, and having to heave for air through the queen's nasty pre-shit flatulence, had certainly not helped ease her nerves for this awful experience. Her eyes were darting wildly in an attempt to watch her captors anus as it was held against her pried open mouth, her instincts telling her to keep watch over the threat before her, even if this would make no difference in her disgusting fate.

Above her, Chrysalis was smirking cruelly, her deep-green eyes glowing with victorious glee. She enjoyed every rattle of her toilet's bindings as the Ex-Princess thrashed against them, to no avail. Even more than that, she adored the endless, panicked screams of the bound equine, and the feeling of her desperate breaths against her unwashed anus and marehood. Oh, the humiliation she brought upon that filthy horse by merely sitting here, having her endure her scents and superiority.

"Thleaaase! THLEAAAASSSSEEEE!! " Celestia begged loudly, her words unable to properly form due to the hooks that held her unfortunate maw agape and ready to receive its torturous meal.

She could feel the Queen's royal anus unfolding lightly against her parted lips, a light crackling sound accompanied by a light fart, the puff of rancid gas oozing into her mouth, the scent burning her tongue like a toxic torch. The queen's sadistic smirk was turning to an expression of almost orgasmic joy, her cheeks turning redder as her eyes gently rolled upwards. She had been fantasizing about this for years. Oh, how often has she not imagined herself defiling the filthy horse-goddess in this manner. Now it was finally happening, and it was even better than she dared dream about.

The queen's mouth slid open, strings of saliva connecting her two rows on deadly teeth, soon broken as her long tongue rolled out, laying across her thick lower lips, her breathing turning louder, while she strained herself.

Celestia's screaming only got louder as she felt the anal kiss against her lips. Heavy tears streamed down her cheeks, mixing with the urine. She wailed like a child who thought their parents gone. She wailed on the very top of her lungs, as Chrysalis sighed in sadistic euphoria, her tainted flower unfolding like an unholy rose blossoming with torment.

"WHAAA! WHHAAA! AARRRGGGGHHH!!! Arggghhh. .. Ch . . Mmnn. . Ugh.."

At the very climax of her screeching cries, Celestia's voice was muffled. All at once, she felt almost silent, her white cheeks turning green with disgust, and her teary eyes rolling back with utter nausea.

Chrysalis's thick, dark log slid across her equine tongue and slowly it made it passed her uvula, triggering her gag reflexes. But any natural reflexes her body had were quickly drowned out, as her queen continued to unload her foul waste, her log soon lodging down into her throat, preventing her from puking.

" Argh ... a ,... urgh .... *whimper* "

There was nothing Celestia could do while she was being forcefed this way, the vile fecal stench was oozing out of her own nostrils with each strained breath she took. The soft, yet solid log of changeling waste was pushing deeper into throat, soon sliding down her esophagus.

"Eat it, Celestia ~" The queen uttered in evil bliss as she felt her reeking waste fill her prisoner's throat. Chrysalis could smell her vile waste from where she sat, and while she didn't find she scent pleasant in any way, the thought of how horrible an experience Celestia was having made her enjoy every vile whiff. Her thoughts were skipping straight past how unpleasant it was for her, and straight to how much worse it was for her victim, bathed in the stench. Choking on it, like a cock of defilement.

Celestia, was not given a choice anyway. The queen's log of dung was girthy and filling, and as it slowly snailed its way into her, deeper and deeper. Her body was given no choice but to gulp it down.

The taste of fresh, warm, bitter waste was increased tenfold as she started sucking down the gross dump. The feeling of lumps of shit breaking from the main load and gliding down had her in a haze of utter suffering. Yet, she swallowed. She gulped down piece after piece, her face wilting like a flower with each consecutive slurp of fecal-matter, the back of the turd liquifying with her saliva, making it go down easily, as much as she wanted it out.

This was utter bliss for the new queen, and literal hell for the former princess turned toilet-slave.
