Part I - Breaking Twilight

Part One:
Breaking Twilight

The first thing that Twilight noticed as she came to was the smell. Or more accurately, the stench. A foul, bitter odor greeted her as she groggily opened her eyes. It took her a while to comprehend her surroundings - a dark, stone room with faint neon green glows illuminating passageways leading out in different directions.

A hard, stone-cold floor pressed into her body, and the alicorn weakly pushed up off of it with a groan. In a half-sitting position, she desperately tried to make heads or tails of her situation. There was a constant, faint chittering sound, not unlike hundreds of light hoofsteps skittering around distant hallways, and the buzzing of insect-like wings.

Twilight looked around, trying to locate where the idle noise was coming from. It seemed to emit from everywhere around her, echoing around the empty room. Then, all of a sudden, it stopped, and an eerie silence surrounded the small pony.

“Well, well, well,” a hissing, echoing voice suddenly reverberated throughout the room, shattering the uncomfortable silence. “The little, purple princess is finally awake.”

Twilight’s eyes darted around the dark room, and she swung her head around into each corner. The distorted voice was oddly familiar, but she couldn’t quite place where she had heard it before.

“I had wondered about you for a while, you know,” the voice continued. “I heard the rumors about Equestria’s new princess of friendship. But I never would have guessed it was you.”

The alicorn could hear the contempt dripping off of the word “friendship,” even without seeing whomever it was that was speaking. The guttural, unnatural nature of the voice made a shiver go down her spine. “W-who are you? Where am I?” she finally managed to ask.

A chittering, cackling laughter erupted from the unseen speaker. “Foolish little pony,” it hissed. “Are you really too stupid to realize? I’ve been told I have a disssstinctive voice.”

As the creature emphasized its hissing slur, Twilight’s blood ran cold. Slowly, she came to realize who it was that was speaking, and where she must be.

“Chrysalis,” she said, a newfound anger filling her voice. “I should have known.”

“Yes,” the taunting voice replied. “You should have.”

Twilight suddenly detected movement above her. She looked up and watched in horror as Chrysalis came into view, crawling down the walls of the room like a spider. Her neck was unnaturally twisted back to glower smugly at Twilight as she hung, twisting the right way back around with a sickening crunch of bone and flesh as she reached the floor.

“Hmmm, you look a little uncomfortable over there,” the changeling hissed with a cruel grin. “Was it something I said?”

Twilight forced the disgust and fear back down, choosing instead to bury it beneath her anger. “Why am I here?” she asked, refusing to let Chrysalis see any of the anxiety coursing through her veins.

Chrysalis gave her a non-committal shrug. “Why not?” she asked. “If it makes you feel any better, you’re not alone.”

The room Twilight was in suddenly got brighter, a sickening green glow illuminating the entire space. She was in a cave, it turned out, but that wasn’t what grabbed her attention. Off to the side of the room, large cocoons hung from the ceiling, and inside each was a pony. The comatose faces of Celestia, Luna, Cadance, her friends, her brother, and countless others sent a chill down her spine.

“Y-you’ve been busy,” Twilight said, trying and failing to put on a brave face. The reality was that the sight terrified her.

Chrysalis let out a cackling laugh. “Drop the act, Princess,” she spat out. “You’re scared shitless. There’s nothing you can do, and you’re realizing that right now.”

The Queen was not wrong. For the first time in a while, Twilight had absolutely no idea how to fix this. She didn’t even know if she could hope for a way to fix this.

Twilight did not have time to dwell on this thought, however. Changelings began to crawl out of the shadows, and gathered in a group around Chrysalis and the alicorn. Their low, chittering hisses and hushed whispers sent chilled shivers down Twilight’s spine.

Chrysalis clearly revelled in her captive’s discomfort. A wicked grin was plastered to her face as she watched Twilight sink lower and lower into her defeat, a most wonderful juxtaposition from their previous encounter.

“My my… How the tables turn. Isn’t that right, little pony?” she hissed sarcastically. “It fills me with great pleasure to see you on the opposite end of this affair.” Twilight warily met her gaze, anxiety evident on her face. “Mmmm, yes. Soon, you will find out how delicious raw, untamed love is,” Chrysalis hissed as she idly paced around the outside of the group. “But unfortunately, you are not in a state to consume emotions yet. Your transformation has not yet begun.”

Twilight’s face paled at the words. “M-my transformation?” she asked, barely above a whisper. “My t-transformation into w-what?”

A cackling laugh dwarfed her feeble voice. “Why a Changeling broodmare, of course! What else?”

A new feeling of dread washed over Twilight at the realization. Chrysalis wanted her not only as a prisoner, but as a tool. She would service them, be of use to them. And that was so much worse than just being held captive.

“N-no,” she stammered in disbelief. “I won’t! I won’t do it!”

“I’m afraid you don’t have a choice, little pony,” Chrysalis sneered. Then she turned to her drones. “Hold her down!” she ordered, and the swarm rushed in. Rough hooves grabbed onto Twilight’s four legs and roughly pressed her down against the hard stone ground of the cave.

“No, wait! Stop! Please!” Twilight begged as she struggled against them to no avail. Even if individually, the drones were weak, there were too many of them to fight off.

Chrysalis laughed haughtily as she watched the mare get pressed down against the ground. “Foolish pony,” she hissed. “When will your kind learn that it is useless to fight back, and just submit?”

Twilight barely paid any attention to the Queen’s words, too focused on trying to fight her way back up. She shrieked as something hot and slimy suddenly began to smear across her legs. The alicorn turned and watched as the changelings holding her down began to secrete a viscous green goo from their mouths, essentially webbing her down to the floor. She fought the urge to gag at the repulsive feeling of it matting down her fur.

Eventually, she was held down by the substance alone, her body spread eagle across the floor. The changelings skittered back and away as their Queen advanced forward, a salacious glint in her neon green eyes.

“And now, at last, the Pony Princess presented before me,” said Chrysalis, her voice nearly cooing. She ran a hollow hoof lovingly against Twilight’s cheek, and the alicorn twitched back away from the touch instinctively. “You’re mine, Twilight Sparkle,” she said quietly.

A cold shudder ran down Twilight’s spine at hearing her name on Chrysalis’ tongue. She tried her hardest to pull away from the changeling’s unwanted touch, but she couldn’t get very far. The slimy webbing around her legs had solidified into thick masses of a resin-like bonding. As hard as she tried, she wasn’t going anywhere.

Chrysalis backed away, her changeling swarm following. Twilight was silently thankful for the distance, but was incredibly wary of whatever was going to come next. The Changeling Queen appeared to be directing her subjects to do something, but the alicorn could not discern what it might be from the insect-like chittering.

Several changelings went over to the side of the room and latched on to the cocoons imprisoning Celestia and Luna. They bit through the slimey material tying them to the wall, and dragged them over to the center of the room. Then, with surgical precision, they sliced open the chitinous chrysali and tore the fleshy sacs open.

The limp bodies of the two royal alicorns tumbled out of their casings, ungracefully splaying out onto the floor. The action seemed to have no effect on them, and Twilight panicked for a moment, thinking the worst. However, their chests rose and fell with the miniscule motions of their breathing. They weren’t dead. At least not yet. Twilight had no idea what plans the Changeling Queen had in store for them.

The torn cocoons were discarded, and four Changelings stepped forward, two for each princess. They took a hold of their limbs, and unceremoniously dragged them right in front of where Twilight was restrained. Then, without any modicum of respect, they parted their highnesses' hind legs and dragged their tails out of the way.

Twilight quickly glanced away, not wanting to tarnish her fellow princesses’ dignity. “Oh, come now, Princess,” Chrysalis admonished playfully. “Don’t be a prude! Take a nice, long look at these pristine, pony princess pussies!”

A sickly green magic took hold of Twilight’s head, and she was forcefully turned to look at what Celestia and Luna had on display. Both of their vaginas were, in fact, what Twilight would call perfect. The young alicorn couldn’t help but be captivated by the forbidden sight, however, she was not prepared for what was to come.

Twilight looked on in horror as large, turgid horsecocks suddenly began to slide out from hidden sheaths beneath the drones with large, round sets of balls dropping down to accompany them. The massive endowments were almost comical in size, but the alicorn was too caught up in the fear of what was about to happen to appreciate such comedy.

“No!” she cried out. “Don’t!”

Chrysalis turned her attention back to her. “Why not?” she asked. “Do you want to take their place?” Twilight didn’t answer, instead unable to tear her eyes away from the sight of the changelings lining their cocks up with the sleeping princesses’ pristine rears. “Don’t worry, you’ll get your turn after them.”

And then, without any ceremony, the changelings slid inside.

There was no reaction from the sleeping alicorns as they got double teamed. The first changeling slid into Luna’s pussy with relative ease and a wet, slick sound as the thick rod of changeling meat parted the deep blue flower. A slapping sound started to steadily ramp up in volume in time with each of his thrusts. The one below had a slightly more difficult time squeezing its way into her tight anus, but it wasn’t long before he too began to steadily fuck Luna’s ass.

Celestia’s breath hitched lightly in her sleep as both cocks slid into her with little to no effort, and the princess involuntarily widened her spread legs to allow the changelings easier access. Twilight winced as she saw flecks of brown smear across the rim of the alicorn’s white anus.

They pumped in and out of the limp bodies, brutally fucking them without any remose or limit. They panted and groaned in pleasure as they pistoned their cocks in and out of the princesses, enthusiastically violating them as they quickly approached their climaxes.

It didn’t take them very long to do so.

Almost simultaneously, all four changeling drones hilted themselves inside their respective holes as they came, pumping their cum into the two sleeping princesses. The off white spunk spurted out around their cocks as they pulled out, and Twilight gagged at the gross sight. As one of the changelings slid out of Celestia’s ass, Twilight gawked as she saw it was not only stained with his cum, but also tinted brown to match the smeared mess around the white alicorn’s anus.

Without any hesitation, the four drones descended upon Twilight, dangling their used cocks in her face. Twilight grimaced and turned away, trying to avoid the turgid members, only to be met with the sight of another one.

“Clean them, Twilight Sparkle,” Chrysalis hissed. “Slurp the love off of their delicious cocks. Don’t let any go to waste.”

The Queen’s magic grabbed a hold of Twilight’s head, guiding the alicorn towards the first pair of phalluses. “No…” she whimpered as the damp members brushed against her face. “Please! I don’t want to!”

“Do it!” Chrysalis hissed, her magic prying the alicorn’s mouth open, and one of the changelings thrusted its cock into opening.

The salty taste of changeling cum and mare juice filled her mouth, and Twilight reflixely ran her tongue against the intruder. The oral organ slurped more of the spunk off of the dick, the slimy texture making the alicorn’s eyes bug out as she tried to pull away. But Chrysalis’ magic held her firmly in place, and she had no choice but to continue to fellate the drone.

As soon as the first one pulled out, a second took its place and she was forced to clean that as well. Twilight unenthusiastically allowed the changelings to wash their cocks in her mouth, providing as little oral attention as she could aside from a few reflexive licks. Between each one, Chrysalis forced her mouth to stay closed, proving no other option but for Twilight to swallow the sexual grime that clung to her tongue and lips before the next one slid inside.

Then, a dirty, brown dick was suddenly shoved in her mouth and Twilight nearly gagged. The foul flavor of pony shit rubbed off on her tongue, and Twilight was intimately aware that it was Celestia’s poop that was being rubbed off into her mouth.

She practically spat the dick out of her mouth as the changeling stepped back, his cock once again back to it’s proper color. Twilight tried to get the lingering taste out of her mouth, but was stopped as Chrysalis’ hoof reached under her chin and lifted up her head to look her in the eyes.

“Don’t fret,” Chrysalis said in what Twilight assumed was her most reassuring tone. “You’re going to hate this at first, I won’t lie to you. But by the end, you’ll be begging for my eggs, begging for my touch, begging for my shit…” the Queen trailed off as she saw Twilight’s eyes widen with each word. They practically bugged out of her head by the time she reached the end of the short list.

Chrysalis chuckled - a grotesque hybrid between a hissing cough and a wet chittering sound. “Hmmm, did that last one trip you up?” she asked, a wicked glint in her eyes. “If you’re going to be my broodmare, we need to make a few… anatomical changes. Namely, you need to be more like a changeling.” She began to slowly circle around Twilight’s immobile form.

“And tell me, Princess, do you know what sustenance a changeling derives nourishment from? Love. And tell me, Princess, can you consume raw emotions?” Chrysalis paused, looking down at the alicorn. “Can you?”

Twilight silently shook her head, not liking where this was going. “No, you cannot,” Chrysalis affirmed. “And to be quite frank, you never will be able to. That is an ability unique to pure, egg-hatched changelings.” She resumed her pacing, yet another evil smile taking over her face. “Which brings us to our main problem. If you must consume love to survive, how are you going to get it?”

By now, Chrysalis had done a full circle around Twilight, stopping in front of her once again. Her menacing eyes bore down into Twilight’s emanating pure evil intention. “There is no need for you to fret over this trivial matter, however. I am a gracious host, and thus I shall provide all of the nourishment you shall need.”

Chrysalis stepped in closer. “I consume lots of love. More than I need, honestly.” She patted her thin belly, mockingly poking at the gaunt flesh. “Does it show?” Twilight gave no response, still terrified as to where this exposition was heading. “So, as with most changelings, there is some unprocessed love that just… well I suppose you say it goes to waste.”

Oh, sweet Celestia, please no. Twilight silently begged to whatever deity might be listening that this was some sick cruel joke and she would wake up in Ponyville on her soft comfy bed and none of this was actually happening.

But Chrysalis’ movement anchored her back in reality as the Queen took another step closer to the frightened mare. “Oh, yes, that’s right. I can see that you know exactly where this is heading,” she drawled with a faint hiss. “But let me spell it out for you anyways.”

“Changeling feces is full of love, just ready for you to consume.”

And there it was.

“Oh I won’t bore you with the details, you’d probably enjoy it too much,” Chrysalis said with a wave of her hoof. “But just know that it’s the only real way for a non-changeling to actually feed on love. Of course, there isn’t a lot of it left behind. Most of it is absorbed by the changeling. We’re not that inefficient, obviously.” She bared her fangs in a wicked smile. “It’s no problem of course. That just means you’ll have to eat a lot more of it to get your fill. And we have plenty to give.”

The Changeling Queen leaned down even further, bringing her muzzle right up in front of Twilight’s. “So tell me, little pony, are you hungry?”

Twilight violently shook her head no. No way. There was no way she was going to do this. She would rather starve to death than eat Chrysalis’ rancid shit.

“No? Oh that’s too bad,” Chrysalis pouted as she backed away. “Cuz I have a fresh, warm meal cooking for you, already. I put a lot of time into it when I heard we were having guests.” A quiet poot came from behind her, and Twilight visibly paled as she realized what the sound was. “Oh, and it sounds like it’s almost ready!”

Chrysalis turned around, revealing her flank to the alicorn. The thin, translucent tail barely hid anything, but she flipped it up and out the way anyways, giving Twilight an unobstructed view of her rear.

“Oh, Celestia, please no,” begged Twilight, a twinge of panic barely hidden in her voice.

The Queen only laughed in response. “You can look for yourself, but I don’t think she’s really in any position to help you right now.”

The filthy anus in front of Twilight suddenly flexed, and an onslaught of foul air exploded against her face. The boisterous fart took the alicorn by surprise, and she unwillingly inhaled most of the noxious fumes. A rotten odor overwhelmed her sinuses, making her gag and choke on the anal air, trying to force it back out of her lungs.

Another fart ripped out into her face immediately after the first, this one more wet and more potent. Twilight clenched her eyes shut as she felt particulates of Chrysalis’ wet waste spew out against her face along with the nasty wind.

“Oh, you’ll have to excuse me, little pony,” Chrysalis cackled. “But you’d better get ready for more.”

Twilight barely heard the changeling’s condescending remarks, she was too busy focusing on not breathing in the stinky air. However that was becoming harder and harder as yet another disgusting fart blew out against her face. She couldn’t hold her breath forever. The alicorn was forced to take in a deep breath just as another rancid burst of air squeezed out of the changeling’s rear, and the scent knocked her back. But the changeling was to have none of that.

Chrysalis lit her horn and pulled Twilight’s face back up close to her smelly ass. She forced the alicorn’s face deep into her crack, pressing her nose right up against the wrinkled star as she let another stinky fart rip out into the Princess’ face. The hole opened and the puckered flesh vibrated right against Twilight’s nostrils, forcing the foul air right up her nose. She coughed through the thick stench and desperately tried to expel the toxic fumes from her lungs, but to no avail. Chrysalis just filled them with more.

Her mind was completely consumed by the potent aroma of changeling flatulence. Rotting, digesting something overwhelmed her senses. Twilight had no choice but to keep breathing in over and over again. How could anypony possibly have this much gas inside of them?

Finally, after what felt like an eternity, Chrysalis stopped farting. Her anus continued to flex however, lightly sullied by the thick bursts of anal air she had produced. “Mmm, did you enjoy that, little pony?” she asked sultrily, flexing her asshole even more. “I certainly did. I was even fortunate to get a few whiffs of that mouth-watering scent up here.”

The Queen looked back and watched as Twilight gasped for fresh air, the pungent odor still hanging around her head like a cloud. “You’ll come to love that stench, Twilight Sparkle,” she hissed. “It’ll become your scent of home, your desired perfume, your life.” One more fart ripped out of her ass as if to punctuate her words, unwillingly being sniffed up by the purple pony’s nostrils.

“But, now, Princess,” Chrysalis continued, turning back around and grunting. “It’s time for your meal.”

The dirty, black anus twitched, its wrinkled surface began to pucker in and out. Light airy wisps of gas slipped out in time with the flexing, but their additions barely contributed to the smelly atmosphere.

Chrysalis’ butthole flattened outward under the massive load that was waiting in her rectum. She had been planning this for weeks - months even - and the Queen had been sure to save up a gratuitous amount of changeling scat just for her guest. “Are you ready, Twilight?” she asked with a resonating hum.

The alicorn frantically shook her head no. “No!” she cried out. “Please no!”

“Mmm, too bad… here it comes,” Chrysalis said as she began to push.

The anus pushed outward before it stretched open around the head of a massive turd. Chrysalis sighed as it started to slide out, the large chunk of waste pleasantly stretching her rosebud with its girth.

Twilight closed her eyes and turned away, desperate to get away from the approaching scat. The log pressed out against her cheek, smearing across her face as it continued to slide out. She whimpered as the gross paste draped over her, breaking in half and falling onto her fluffy chest below.

“Hold her mouth open!” Chrysalis ordered, and two drones swooped in to grab at Twilight’s face. She tried to fight back, but it was useless. Their hooves reached down and pried her muzzle open, holding it up to the wide open asshole in front of her.

Chrysalis’ anus flexed again, an airy fart sputtering directly into Twilight’s mouth as she started to push again. The puckered ring stretched wide around a second log of shit, crackling as it was pushed forward right into the pony’s waiting mouth.

The compressed texture of the poop slid across Twilight’s tongue, coating her taste buds with a disgusting, bitter flavor that nearly forced her to gag. Cleaning the changeling dick from Celestia’s ass was nothing compared to what she was experiencing right now. The foul taste seemed to seep into her tongue, the flavor threatening to overwhelm any and all of her remaining senses.

Tears welled in Twilight’s eyes as her mouth continued to fill with the stinky waste of the Changeling Queen. She refused to swallow, forcing the shit to pile up and collect in her maw. It packed into the pony’s mouth, filling it to the brim. The remainder of the poop that couldn’t fit slid out around Twilight’s wide lips and dropped onto her chest in a sloppy coil.

Twilight desperately tried to force the mound of horseapples out of her mouth, but Chrysalis continued to push more and more out. The mound on top of her was beginning to grow, the dull brown scat beginning to stain the pony’s pristine lavender fur.

It was not long before she had no choice but to swallow.

With a great amount of effort, Twilight bit down into the crap filling her mouth. Her flat teeth cut through the muck, releasing a much more potent and horrendous flavor than she could ever imagine. The bitter taste exploded into a conflicting mess of nasty, earthy glop. Her throat spasmed as she tried to throw up, but the absurd amount of feces in her maw prevented anything from actually coming up. The alicorn had no choice but to keep on chewing, and desperately try to choke the disgusting shit down.

Twilight managed to swallow her first mouthful, clearing room in her mouth for more. Chrysalis immediately filled the empty gap, her anus squeezing out another soft turd and packing it into the hole.

“You’re going to have to pick up the pace, Princess,” Chrysalis called back to her. “It would be a shame to let so much of my thoughtfully digested love go to waste!” Her goading was accompanied by even more shit sliding out of her ass.

Twilight did her best to keep up, if only to discourage further vocal intimidation. She chewed through the earthy muck, forcing it down her throat as more plopped in to replace it. Chrysalis did not relent, and she cackled as she deposited more and more scat on top of the alicorn.

“Eat your fill, little pony!” she cried through her maniacal laughter. “There’s plenty more to come!”

Twilight pulled herself backwards, leaning up against the rough stone wall of the hive. Sticky fluids - a mixture of piss, cum, and other unspeakable filth - matted down the fur all over her body. Her mouth was smeared with the thick, stinky remains of the changeling scat that she had just been forced to eat. Bile rose in the back of the throat at the fresh memory, but she forced it back down. She would not show any more weakness in front of her captors.

She looked down at her ruined coat, the once pretty lavender hair smeared and stained a deep brown with Chrysalis’ creamy shit. Twilight willed herself not to cry, not in front of them. Instead, she simply watched with defeated eyes as a number of drones hefted the limp bodies of Celestia and Luna up and back into their glowing chrysali.

As if to add insult to injury, a dull splattering sound filled the room as a pale yellow stream of urine suddenly arced onto Twilight’s breast. The hot fluid sprayed across her chest, soaking into her fur and dribbling down to her crotch.

Chrysalis stood above the alicorn, her hind leg cocked back like a dogs as she pissed onto her newly christened changeling slave. Twilight did not even lift a hoof to resist and reigned to just letting the queen continue to defile her. At least it would wash away some of the poop.

“I hope you enjoyed what will be your first of many meals,” Chrysalis taunted smugly as her pee stream tapered off and she lowered her leg. The tall changeling turned to tower over the alicorn. “And if you didn’t… well… just be patient. You will eventually.”

The evil smile somehow managed to dwarf the horror of the grotesque act Twilight had just endured. The pointed teeth signified so much more to come, and she was terrified. All she could do was hope that somewhere, somepony knew that she was missing, and knew where to come and find her. But until then, Twilight was on her own.

And there was only so much more of this disgusting, de-equinizing filth that she could endure before she started to break.

Part II - Twilight Breaking

Part Two:
Twilight Breaking

The following days were much the same for Twilight. She was harassed and fed often, sometimes multiple times per day. Thankfully, the drones had not taken to brutalizing her as they had with Celestia and Luna, even if they appeared to be in a constant state of arousal.

Changelings would walk through her isolated little cave, cocks out and with large, swinging testicles dangling behind them. They were crude, vulgar displays, and to add to her humiliation, they barely affected her anymore. If anything, she had gotten used to them. The sight of thick changeling cock no longer surprised or disgusted her - it had become a new normal.

She didn’t really know how she should feel about that.

There was also a constant, lingering smell that hung in the air. Part of it was undoubtedly from the perpetually exposed sweating genitals of an entire changeling hive. Their heavy musk mixed with the rotting stench of stale shit and piss that coated her body and the ground around her, creating a potent odor that constantly burned her nostrils.

But the worst part was that she was getting used to the foul smell as well. It was still fairly unpleasant, but it was only a matter of time before she became fully noseblind to it.

The final development was perhaps the most disturbing of all, however. The last time that Chrysalis had been through here, Twilight found that the stench of her fresh poop made the stench more bearable. It sickened her that she preferred the pungent odor rather than the lingering aroma. However it was getting harder and harder to deny that fact as Chrysalis stepped into her little alcove.

A shudder rippled through her body as the faint stench of Chrysalis’ ass reached her nostrils. Even though the Queen had just entered the room, her heady aroma had already drifted towards Twilight’s nose. She breathed in deeply, trying to get a stronger sense of the smell, before she suddenly recoiled in shock.

Had she really just done that? Was she really craving the foul stench of changeling shit? What was happening to her?!

Twilight tried to reign herself in, but unfortunately, it seemed that Chrysalis had already noticed her slip. “Hm, enjoying yourself?” the Queen asked with a sly smile. “I told you that you’d come to love the role you were meant to play.”

The alicorn glared back at her. “I know you’re using some kind of magical influence on me,” she growled. “Even if it is working, it’s still against my will.”

To her surprise, Chrysalis chuckled at the retort. “Oh, Twilight. The naivety of you ponies is endlessly surprising.” She waved a hoof and pointed between them. “There is no magical influence on you whatsoever. I wouldn’t force you to break. I want it to be slow, gradual, and satisfying. Magically breaking you would be too easy.” She took a few steps forward. “You just won’t admit to yourself that you’re actually enjoying this.”

Twilight didn’t really know how to respond to that. The idea that she was slowly becoming like this of her own volition was such a foreign concept to her. She wasn’t actually becoming a depraved mare, was she? She didn’t actually like this, right?

“I can see the gears twisting in your head,” whispered Chrysalis as she leaned down next to Twilight’s ear. “You don’t want to believe it. But it is true.” Her tongue slithered out and faintly licked along the tufted ridge of the alicorn’s lavender ear, making it twitch in response. “Do you want me to prove it to you?”

Twilight wanted to say no. She wanted to yell in Chrysalis’ face and tell her that she would never turn - that she would never be like her. Piss and shit and being used like a common whorse did not and would never appeal to her. Twilight desperately wanted to deny all of these things. But a growing part of her was begging for her to say yes.

“I’ll take your silence as a yes,” the queen hissed with a sadistic grin and backed away. “I had a feeling this would happen soon, so I came prepared.”

Twilight knew what was coming as Chrysalis turned around and bared her filthy ass to the alicorn. This had gone down the same way several times before, and she had regretfully gotten used to it by now. But this time was a little bit different.

The Queen’s butthole was disgusting. Twilight had gotten used to the changelings’ lack of general hygiene back there, but this time the butt was even more messy than usual. A thick layer of brown, drying waste caked the puffy pucker, and streaks of shit radiated outwards, staining the black cheeks. The foul smell of stale scat grew ever stronger as Chrysalis magically pulled her ass open, forcing Twilight to see and smell all of her dirty ass.

“As you can see, I’ve worked hard to prepare this one for you,” Chrysalis said. “Dietary variety is very important after all.” She waved her tail and wafted more of the odorous stench into Twilight’s face. “Now, get licking.”

Chrysalis pushed her ass back against the purple pony’s face, pushing her muzzle deep into her crack. Twilight whimpered as her nose pressed right up against the wrinkled surface of the dirty pucker, and greasy shit smeared across the tip. The potent smell of shit flooded her senses, and she forced back the gag that rose in the back of her throat. But she didn’t dare try to pull away, and instead parted her lips and stuck out her tongue.

The alicorn gingerly ran her tongue across the surface of Chrysalis’ pucker, grading it through the crappy muck. The filth smeared across her tongue, coating it and letting the taste fester against her taste buds. The stale shit tasted bitter, not unlike the fresh changeling scat she had been forced to endure for days now. If anything, the sensation was duller than usual.

Her second lick was less hesitant, and Twilight pushed her oral organ against the anus firmly, scraping the dried shit off of the wrinkled star and smearing it into her own mouth. Each subsequent lick got more and more enthusiastic, and soon, Twilight was eagerly making out with the changeling’s anus.

Chrysalis pushed back against the muzzle between her cheeks, gently grinding against Twilight’s mouth. She flexed her pucker against the dutiful tongue, encouraging the alicorn to push deeper into her rectum. “Mmm, you’re quite good at this, Twilight Sparkle,” she murmured. “One might start to think that you’re enjoying cleaning my shitty ass.”

Twilight ignored the goading. To be honest, she was too absorbed in the ass in front of her to even hear them clearly. She simply continued to push into the anus, and licked and slurped and sucked on the puckered flesh as much as she could. Her tongue dug through the thick filth, gleefully sucking globs of shit off of the wrinkled flesh.

The tight hole started to flex rapidly against her tongue, signaling the oncoming release. Twilight gasped as the brown star opened up to let a rancid fart burst out right into her mouth. The explosion of gas was unexpected, but did nothing to deter the alicorn from her current goal. She sucked down the foul anal air as it spewed out, practically huffing the disgusting farts down as she continued to slobber over the pronounced pucker.

“You’re disgusting,” Chrysalis degraded, squeezing even more gas out of her colon, directly into the alicorn's face. “You’re laying there, eagerly sucking shit off of my ass and snorting down my rancid farts. Some princess you are.” A particularly loud and wet fart ripped out, and its ripe stench singed Twilight’s nostrils as she breathed it in.

When there was no more grime on the wrinkled hole, Twilight spiraled her tongue outwards as she began to clean the inner cheeks of the Queen’s ass as well. Her tongue scooped more and more filth off of the smooth, dark flesh, infusing her senses with the foul taste and scent of Chrysalis’ waste.

A loud, long moan rose out of Chrysalis’ throat as her entire backside was orally cleaned by the former princess. The teasing trails of the pony’s tongue on her ass sent ripples of pleasure through her, and she fed heavily off of the massive amounts of lust simply oozing out of the mare.

But all good things had to come to an end, and soon, her butt was clean enough to eat off of. (Not that it being absolutely filthy would stop Twilight Sparkle at this point.) The Queen pulled away, standing up and turning around. She looked down upon the pony below her in satisfaction, noting the deep brown smears around her muzzle.

Twilight only realized what she had done as the delicious ass was pulled away from her. She fought back a gag as all of her senses suddenly revolted against her, and it was as if the disgusting, bitter taste had just settled in her mouth. Her breath tasted and smelled awful, having just been used as a personal asswipe for the changeling queen.

How had she even begun to think she was enjoying this?

“You’ve done an excellent job, pony,” Chrrysalis complimented with a sinister grin. “I’m glad to see you’re finally truly taking to your new role in my hive.” Twilight looked down in shame, still in disbelief that she had actually done that. “However, there is one more activity that you need to indulge in before you can fully call yourself a broodmare.”

Chrysalis stepped over Twilight, towering above her restrained form. The alicorn flinched back as she continued to step forward, until she was practically standing on top of the purple pony, with her thin legs spread wide around her cowering form.

Twilight’s attention was pulled away as the hard chitin near her hind legs suddenly shifted, pulling back as an appendage slowly slipped out from the newly formed gap. It was dark black, just like the rest of her body. However, as it slowly pulsed and got harder and harder, the tip began to shift into a dull green neon glow. It extended further and further until it was nearly the length of Chrysalis’ entire undercarriage, and it was almost touching the tip of Twilight’s muzzle.

The alicorn gulped as she realized the appendage was the same shape as a horsecock. The only distinctions being its far longer length and the oddly shaped flared head. It flexed in time with its pulsing bioluminescence, hovering above her with an imposing authority.

“Well, little pony, what do you think?” came Chrysalis’ voice from somewhere above her. “Think you can handle it?”

“W-what are you going to do with it?” Twilight asked weakly. But deep down, she already knew the answer. Chrysalis simply stepped even closer, nearly poking her in the face with it. “P-please don’t put your p-penis in me…” whimpered the alicorn. She had sworn not to give the changelings any more satisfaction in her suffering, but this was quickly pushing it.

Chrysalis laughed at her. “Penis? What penis?” she almost cackled. “Don’t worry, Twilight Sparkle, I can’t put something inside of you that I don’t have.”

Twilight was practically cross-eyed as she stared at the massive dick bobbing in front of her, so she really didn’t know what Chrysalis meant. She could see the damn thing! Was this some sort of new psychological torture method? Telling her prisoner that they were imagining what was actually happening?

“It’s an ovipositor,” Chrysalis explained, flexing the large organ in front of her. “Not a penis. It can provide equal amounts of pleasure, however. Maybe even greater.” Twilight could practically hear the vile grin on the Queen’s face as she explained. “And you’re going to become quite acquainted with it.”

Chrysalis thrusted forward, pressing the phallic organ into Twilight’s muzzle. A glob of pre (or whatever it was that an ovipositor secreted) smeared across her lips, streaking down her cheek. The alicorn grimaced as she saw that the viscous fluid was glowing a sickly green color. She really didn’t want to know what it could possibly be.

“Lick it,” Chrysalis commanded as she thrusted forward again.

Deciding it wise to comply, Twilight hesitantly parted her lips and extended her tongue. The thick, syrupy fluid oozed out onto her tongue, and a salty-sweet flavor flooded into her mouth. The taste wasn’t nearly as bad as she expected it to be, and as a matter of fact, it was a welcome reprieve from the bitter shit that the alicorn had been forced to consume over the past days. She ran her tongue curiously over the ridged head of the ovipositor, trying to sample more of the interesting flavor.

The organ flexed against her tongue, and Chrysalis let out a pleasant sigh. “That’s it. Lick all that delicious lube up,” she said and pressed forward even further. The flared tip pressed against the pony’s lips, and her tongue swirled around the tip before her lips parted and she let the stiff rod slide into her mouth.

Twilight moaned around the thick shaft, and did her best to run her tongue around all of the ridges and pulsing veins. The texture of the flesh was addictive, and Twilight wanted to feel all of it, everywhere, all at once. She moaned as the heat of the stiff phallus seemed to spread outwards from her mouth and warm her entire body.

Slowly, Chrysalis began to thrust into her maw, and the queen built up her movements into a steady rhythm. Twilight opened up her mouth and throat as much as she could, letting the changeling queen fuck her mouth freely. The alicorn’s mind slowly began to fade into a submissive bliss, and all that she could focus on was the ovipositor as it plunged deeper and deeper into her throat.

In her mind, it was simply a massive, juicy horsecock that was sliding in and out of her throat. Twilight was perfectly content to just lie there and let herself be fucked away into oblivion. The taste, the sensation, all of it built up into a wonderful combination of sexual bliss. It was only an added bonus that the wonderful stiff rod of stallion meat was attached to Chrysalis’ undeniably beautiful and attractive form.

The stiff rod in her mouth suddenly flexed, and the action caught Twilight off guard. She barely had time to react before her mouth was suddenly flooded with a warm, sticky substance. It was slightly sweet, slightly salty, and overwhelmingly thick, but overall not that unpleasant. The alicorn’s eyes slipped back shut, and she began to suckle on the tip of the phallic organ, coaxing more and more of the warm fluid out of the member.

She acted purely on instinct, like a foal sucking from a mother mare’s teat. The only thoughts in Twilight’s mind were how to get more and more of the precious, life-giving nectar. Her mind slipped into a lust-filled haze, and the pseudo-cock pulsed in her mouth and delivered to her what she so desperately craved. And Twilight was in her own personal heaven.

But as Chrysalis’ cumming came to an end, and the thick meat was pulled out of her mouth, the alicorn crashed back down to reality.

Wait, what?

Twilight’s eyes bugged out as her brain caught up with her own thoughts. Was she seriously enjoying this? She couldn’t possibly be...

Chrysalis stepped off of her, backing away as her ovipositor slowly softened and retracted back inside of her abdomen. “An excellent first start, Twilight Sparkle,” the Queen hummed as she licked her lips sultrily. “Now, it’s time for the real fun to begin.”

Twilight had been so caught up in her own thoughts that she had not noticed the large ring of changeling drones that had slowly gathered around her. She looked around at the group, anticipation and fear coursing through her body as she wondered what they were going to do to her. Given the previous few day’s worth of “activities,” she did not have to take too many guesses.

The group of changelings closed in around her and turned around. They lifted their thin, translucent tails, baring their backsides to Twilight. The alicorn looked on in apprehension as she took in each of their low-hanging delicates and smeared anuses. This was really about to happen. Why wasn’t she more disgusted?

A sputtering fart signaled the beginning of the shitstorm to come. In turn, each of the dark black buttholes began to flex, farting out foul-smelling flatulence that descended upon Twilight like a thick cloud. Their disgusting, rotten scent began to build up, filling the room with more and more of the potent odor that the pony seemed to be getting more and more desperate for.

Twilight took in a deep breath, inhaling the anal air and letting it mingle in her brain, mentally preparing her for what was to come. She still didn’t feel the normal revulsion she should have felt, and had she not currently been getting high off of huffing changeling farts, she might have been more concerned about that fact.

Finally, with a drawn-out wet fart, the first of many changeling’s sphincters opened up and began to push out a thick log of shit on top of her. The warm turd slid out quickly, falling down on top of her belly with a dull, wet thud.

An unwanted moan slipped between Twilight’s lips as the vile warmth landed on her coat. Her eyes widened and she went rigid in a mixture of disgust and horror at her pleasure. “No no no no no…” she whispered. “This isn’t happening. I don’t like this!”

But the warm shit piling on top of her was quickly breaking her resolve. The feeling was too pleasing, too intriguing for her to continue begging for it to end.

Twilight splayed out her body even more, as much as she could, and let the poop fall down upon her. The warm logs piled up on top of her, smearing into her coat and slowly burning her with filth. The stink of shit began to fully fill the room at that point, permeating and dominating over everything else. Twilight greedily breathed it in and revelled in its potent stench.

Was she really enjoying this? Enjoying being used as a communal toilet for an entire hive of changelings? Was this really what her existence had boiled down to?

She had no time to keep thinking about it, however. The changeling standing by her head let out a rancid fart by her face and a torrent of fetid diarrhea suddenly sprayed out of the quivering pucker and plopped right onto her face.

The wet and sludgy slop soaked into Twilight’s face like mud, and it was only a matter of time before it managed to get into her mouth. The taste was absolutely disgusting. A horrendous, bitter flavor with undertones of both spicy and sweetness tingled her tongue, and much to her own chagrin, Twilight opened her mouth as another deluge of semi-solid crap squeezed out right into her open maw.

Twilight’s back arched in grotesque pleasure as the vile grime filled her mouth. The slick and heavy diarrhea quickly overflowed, running out over her cheeks and plopping to the stone floor of the cave. A deep, wet fart exploded out, spraying fecal sludge across the alicorn’s face, before it squatted down to bring its anus right up to her lips.

She swallowed the semi-solid shit as quickly as she could, gagging as the bitter waste hit the back of her throat. But she managed to get it all down after a few mouthfuls, and stuck out her tongue. The pronounced pucker flexed against her oral organ as the alicorn began to drag it across the wrinkled flesh, and dutifully cleaned the hole of its speckled filth.

All the while, more and more changeling crap was pushed out onto her body from counteless drones. Logs and droppings of various texture and consistency piled on top of her once lavender hair, now smeared and stoned a deep brown.

Twilight reached down and pushed her hoof through the warm piles of shit on her body. Her hoof smeared the waste even deeper into her fur, breaking the mush apart and creating a thick paste to cover her coat with.

She shoved her tongue deep into the ass on her face, orally cleaning out the drone’s rectum and sucking fecal residue from its colon. Her mind buzzed with gross pleasure as the taste, smell, and feeling overwhelmed her brain. Twilight was teetering over the edge, and she did not want to come back.

Two sharp pin pricks of pain began to blossom in Twilight’s mouth. She pulled out of the messy butthole, feeling at her teeth with her tongue. The small fragment of her mind that was still connected to reality watched on in abject horror as both of her canine teeth fell out of her gaping mouth and tumbled to the floor and two, long fangs began to push forward out of the empty gaps left behind.

She sat there in the pile of filth, watching as more and more fell down on top of her. It just kept coming, each drone being replaced by another as their asses were emptied out on her chest, stomach, teats, pussy, legs, face… the muck encased her like a disgusting cocoon, priming her for the transformation that had only just started.

Part III - Twilight Broken

CONTENT WARNING FOR THIS CHAPTER: This chapter starts off with a pretty gorey transformation scene. If you ain't into that, and just wanna get back to the sexy scat, skip to the first page break. It also contains a retching scene (but no vomit).

Part Three:
Twilight Broken

Urine splattered onto Twilight’s chest as Chrysalis’ dull cackling echoed from across the room. The alicorn’s tongue poked at her new fangs in gross curiosity, feeling them and tasting them. They made her mouth feel too small, and the sharp points nipped at her lips as she opened and closed her mouth.

“It’s finally beginning,” Chrysalis taunted her from some unseen corner of the cave. “I’ll admit, you held out for longer than most, but in the end you fell just like the rest.”

Twilight barely heard the changeling queen. Instead, she was more fascinated at how her vision had started to change. It felt as though her eyes had suddenly gotten wider and her field of view had shifted outwards. The room nearly spun as she turned her head, and the blurring vision slightly nauseated her if she moved too quickly.

Her skin started to feel really itchy, as if she was covered with tiny bugs that had crawled up underneath her fur. She started rubbing at her body desperately in an attempt to try and quell the uncomfortable sensation. Her hooves smeared through the cooling shit that clung to her fur, spreading it deeper into her skin. Then, all of a sudden, she paused as she felt a tugging sensation in her belly.

Looking down, Twilight almost screamed at what she saw. Clumps of her fur were matted around the mushy brown paste that caked her hooves, having been ripped out of her skin. Frantically, the alicorn rubbed harder and looked at her hooves in horror as she pulled out tufts of lavender hair with each pass of her hooves. Large patches of her body were being stripped bald, and beneath them, the once pale purple skin had gradually transitioned to a smooth, shiny black - just like a changeling’s.

Twilight was turning into one of them. She was becoming a changeling.

Her entire soul should have been in a state of horrified shock. But it wasn’t. Instead, Twilight was surprisingly… content with the transformation. It hadn’t been anything she wanted - quite the opposite really. But she was not against the idea at all.

As a matter of fact, it was very quickly growing on her.

Her hooves worked across her body, and they took entire clumps of hair with them. Each tug and pull at her balding skin sent a shiver of pleasure down her spine, and with one, least hard yank, she completely succumbed to that pleasure.

Loud, wanton moans ripped from her throat as the feathers on her wings gradually began to fall out; the skin webbing them together thinning out to a near-translucent state. The flaps were pulled taut against the bones of her wings, and Twilight stretched them out, tearing through it and creating large, round tears in the flesh.

A loud cracking sound echoed in the room as her horn split and became a jagged, holey cusp, and parts of her muscle began to atrophy and sink in, turning her once lean form into a brutalized swiss-cheese shape. Her mane and tail thinned out into a light, almost transparent state, draped across her back and flanks as though they were lifeless.

With a final, sexual scream, the transformation finished. Twilight stood in place with labored and heavy breathing. Her body quivered in untold pleasure as feelings of lust, love and hunger flooded over her.

Chrysalis stepped over to stand before her, a strange look of pride on her face. “Welcome to the hive, Twilight Sparkle,” she said.

The physical transformation prompted the mental one as well. There was something liberating about letting go of all of her inhibitions, and simply leaning into the debaucherous, filthy, hedonistic pleasures of the Changeling Hive.

Where before she would shiver in fear of what the drones would do to her, now she shivered in pleasure. Twilight would let herself be wantonly used by them, and she practically became a personal cum-dump pleasure whorse to service their nastiest desires.

The foul diet that had been fed to her over the past days became her desired meal. If she was just moderately peckish she would call out for Chrysalis, or even the nearest drone, and latch her mouth onto it’s ass to suck the precious pre-digested love from its bowels.

Such was the state that she was in now, her lips locked around Chrysalis’ pronounced, black pucker as she slurped the fresh shit right out of her ass. Her neck bulged around the thick, creamy turds as they slid down her throat, and her lips and mouth were stained a deep brown from the newly deposited scat. Grotesque, wet slurping noises accompanied the dry pops and crackles of the excretion, punctuated by a heavy fart every so often as Twilight reached a pocket of air. The vile sounds were an orchestra to the former alicorn’s ears, and all she wanted was to hear more of it as she tasted the bitter waste on her tongue.

“I’m glad you’re enjoying your meals, little drone,” Chrysalis said. “I know I’m certainly enjoying feeding them to you.” Twilight moaned her affirmation through a mouthful of poop as she vigorously chewed through the filthy muck.

As her bowels emptied, Chrysalis stepped away from her muzzle, and Twilight was briefly confused as to why her queen was leaving so soon. But all of her confusion swiftly melted away as Chrysalis walked around to her rear, lined up her ovipositor with Twilight’s dripping snatch, and slammed home.

A loud, pleasure-fueled moan earupted from Twilight’s mouth, and her eyes rolled back into her head as Chrysalis began to brutally fuck her. The Queen yanked back her head, forcing her mouth to drop open. Brown drool dribbled out as her tongue lolled out, glazing her black breast with thick saliva. She arched her back and angled her rear to push back against the relentless pounding she was receiving and clenched her pussy repeatedly to try and heighten the pleasure.

For her part, Chrysalis was merciless with her thrusts, and she slammed her faux phallus over and over again until it was hilting itself in Twilight’s gaping pussy with each thrust. The green organ rippled as it finally primed its shaft to release the batch of eggs that the queen had been preparing ever since she had first captured the former princess. And now she was finally going to get the chance to plant the seeds of her future hive.

It was not long before Twilight succumbed to the pleasurable pounding, and her first orgasm tore through her body like an electric current. Jolts of painful pleasure arced across her nerves, tingling her pussy and making her shudder in ecstacy. The motion was a singal for Chrysalis to somehow start fucking her even harder, drawing out the intense pleasure that Twilight felt.

Time was lost to the two equines as they fell into a chaotic pleasure-pit of fucking and moaning and groaning. Chrysalis’ ovipositor was now flexing rhythmically as she approached her own release, and with a few final thrusts she slammed home into the broodmare’s cunt, ready to release her eggs.

The tip of the ovipositor opened wide, stretching the flexible entrance to Twilight’s newly transformed cervix. The feeling was intense, and the former alicorn let out a low moan as she shuddered around the suddenly overwhelming sensation of sheer fullness that she felt. She could not help but pant and moan as she felt the slimy orbs slipping out of Chrysalis and right into her own womb, each one filling her up more and more.

Viscous, green goo started to seep out of her pussy around the ovipositor, and the organic lube dribbled down her thighs and dripped to the floor with thick wet plaps. More and more eggs slid out of the phallic organ until Twilight was stuffed as if she had just eaten the largest meal ever. Her stomach was distended with the weight of the new life she was carrying, and her legs trembled as Chrysalis finally pulled out of her.

A gush of marecum, egg-lube, and other unsightly fluids squirting out as the changeling queen withdrew her ovipositor and splattered onto the floor between Twilight’s legs. A low moan was drawn out of her throat as she nearly collapsed, but she rolled over just in time so as to not crush her newly impregnated belly.

“Oh my gosh,” she managed to croak out. “That… that was amazing!”

Chrysalis chuckled as her ovipositor withdrew back into her body. “Mmm, wasn’t it?” she agreed. “There is no feeling quite like it.”

Twilight couldn’t agree more with that statement. She drifted off, content, satisfied, and looking forward to whatever sexual escapades were to come.

As the days passed, and Twilight had yet to experience any effects of her new impregnation, the satisfaction of finally getting bred by her queen was starting to wear off. The drones were no longer allowed to rape her, for fear of damaging the fresh eggs, and she also had no appetite for some unusual reason. Besides, she was eager to experience something new.

Her mind kept drifting back to how the drones had played with Celestia and Luna when she had first woken up, and the more she thought about it, the more she wanted to do something similar. Her intense horniness was driving her actions now, and it wasn’t long before she found herself wandering back towards the cave where she and the other ponies had been held captive.

The prisoners were exactly where they were the last time Twilight had seen them. Wrapped up in luminous green cocoons, suspended from the ceiling of the cave that Twilight had called home for so many days. Celestia and Luna had been tucked back away in their own hanging prisons, neither of them having had any knowledge of what had occurred.

But Twilight didn’t want to play with somepony who was unconscious. She wanted a pony who was awake, who would react to what she was going to do. After all, those reactions were part of the fun, were they not?

In the end, her choice was simple: Cadance. Bordering on incest, deliciously off-limits, and it would finally fulfill the small, childhood crush she had on the princess. Her decision made, Twilight speared through the thin material restricting her, and watched with glee as the princess’ unconscious form tumbled out onto the floor. With just a little bit of magic, Cadence groaned and began to stir.

“Sunshine, sunshine, ladybugs awake,” Twilight’s whispery voice taunted as she circled around the mare. “Clap your hooves and do a little shake.” The newly christened changeling wiggled her backside in Cadance’s face before dragging her thin, translucent purple tail sultrily over her muzzle. “Ah, those were the days, weren’t they?”

The alicorn’s eyes widened as she took in her surroundings before they settled on the changeling in front of her. “T-twilight?” she asked. “What? Is that you? Are you… what happened to you?”

“Oh, nothing much,” Twilight replied with a sadistic grin. “I just have finally evolved into what everypony should desire to be. I’m part of the hive, now.” Her eyes glowed with untold deviousness. “And I’ve decided it’s time to say hello to a few of my old friends… starting with you.”

Her horn lit, and she dragged Cadence up into a sitting position. “Oh, fucking you is going to be so much fun,” she said as she licked her lips.

“T-twily, please…” Cadance whispered fearfully. “This… this isn’t you! Please stop this!”

Twilight’s grin grew even wider. “Oh, but it is me, Cady,” she replied, a demonic spark in her eyes. “And I have absolutely no intention of stopping anything.”

Cadance’s eyes widened in fear as she stared back into the slitted black pupils that radiated pure malintent. This was real, it was happening. This creature really was whatever was left of Twilight Sparkle, and Cadance could feel the powerful waves of lust that poured off of her. The heavy sensation shook the alicorn’s core and she really didn’t know what was going to come next.

“Unfortunately, I’m not allowed to turn you. So we’re going to have to miss out on a lot of the fun that comes with that,” Twilight drawled as she idly paced around Cadance. “But hey, I’m sure that giving you a little taste of the process won’t hurt at all.” Cadance cringed at the wicked smile that crawled across Twilight’s face as she spoke. Whatever the former alicorn was planning for her certainly would not be that good at all.

Cadance grunted as she was magically pulled up into a sitting position and the sudden movement sharply pulled on her fatigued muscles. The new position placed her right at eye level with the underside of Twilight’s smooth breast, uncomfortably close even as the dark skin brushed against the tip of her muzzle.

Twilight kept her body in close contact as she turned around, replacing her front with her rear. Cadance couldn’t help to stop the brush that rose on her cheeks as her sister-in-law revealed her dripping wet slit right before her eyes. However, her attention was swiftly drawn to the hole above it.

Being the princess of love, Cadance had seen quite a few mare rears in her time, and granted, not all of them were the cleanest of places. However, Twilight’s butt was fighting to win the title of the dirtiest that she had ever seen. Dry, flakey specks of old shit clung to the puckered flesh of her anus, and spread outwards onto the asscheeks surrounding it as well. They were thick clumps, as if the mare hadn’t bothered to wash her flank in days if not weeks.

The smell of stale scat wafted down over Cadance, and her eyes nearly watered from the intensity of the aged crap alone. However, she was definitely not ready for what was about to come.

The loud fart that exploded out into Cadance’s face caught her by surprise. She pulled away as much as she could, clamping her mouth and eyes shut and trying to hold her breath. Unfortunately, she hadn’t been quite fast enough, and the pungent odor of Twilight’s anal air settled in her nose. The rotten stench made her eyes water, and she flinched as yet another one blew out against her clenched face.

“Ooof, you’ll have to excuse me,” Twilight chuckled dryly. “My new diet of only love hasn’t been all that forgiving on my digestive tract.”

Twilight’s dirty pucker flexed as another rancid fart slipped out of her rectum. The warm flatulence actually shifted the hair on Cadance’s mane like a harsh, warm breeze. She continued to hold her breath as long as she could, but eventually, her lungs were going to run out of air. Unfortunately, that moment seemed to coincide with a third burst.

Just as the mare began to suck in some air, a loud, wet fart ripped out against her muzzle. Cadance coughed on the thick, smelly air, and nearly gagged as she felt warm moisture flick out against her face, particulates of shitty residue and anal juice no doubt. It was disgusting and vile, and she could only hope and pray that Twilight’s gassy torture would be through with soon.

But that definitely seemed to not be the case. Cadance gasped in surprise as she felt Twilight’s magic take hold of her head and position her directly underneath the changeling’s flank. She stared up in horror, terrified at the prospect of being subjected to more of Twilight’s rancid anal air, and chlenched her mouth shut with a deep gulp of air in preparation for the onslaught.

For better or for worse, more farts were not what was to come.

A burst of hot, deep yellow urine sprayed out against Cadance’s face. The warm fluid soaked into her fur, and she squeezed her eyes shut before any of the acrid fluid could get into them. The arc of piss splattered onto her muzzle, and the heavy scent of dehydrated pee seeped into her nose.

“Open up,” Twilight commanded, and her magic shifted around to pry open the alicorn’s mouth. “Don’t you want a taste of my refreshing nectar?”

The sound of Twilight peeing shifted into a dull echo as her urine stream landed squarely in Cadance’s forced-open maw. The satisfying sound of stream-in-mouth was like music to the changeling’s ears, and she let out a pleasured sigh as she continued to empty out her bladder onto her sister-in-law.

Cadance tried to spit the salty fluid out of her mouth, and it waterfalled out over the edge of her lips. But Twilight simply tilted her head back a little bit more, forcing the piss to drain down the back of her throat. Cadance had no choice but to start swallowing the acidic fluid. The taste somehow got even worse as it hit the back of her mouth, becoming even more salty and bitter. She had to keep swallowing though, less she wanted to be drowned with the former alicorn’s piss.

Twilight continued to waterboard the princess with her hot pee for the next few moments as her large bladder slowly drained itself down her throat. But eventually, she was out of liquid waste and the golden stream slowed down to a mere trickle. It dribbled over Cadance’s breast, marking a dark trail down her front side.

Her pee break finished, Twilight pushed her rear back up against Cadance’s mouth, wiping her wet pussy against the alicorn’s muzzle. “Clean it up,” she ordered. Cadance hesitated, afraid to voluntarily stick her tongue out against the damp folds. This was the wrong choice. “I said clean it up!” Twilight ordered a second time, and she forcibly pressed Cadance’s muzzle deep into her wet cunt.

The alicorn's air supply was quickly cut off, and she frantically stuck out her tongue to lap at the wet folds. She orally wiped marejuice and piss out of the quivering snatch, adding in some extra swirls to half-heartedly try and pleasure the dominant changeling above her.

“Mhmmm,” Twilight cooed. “That’s more like it. Let’s see some of that fancy tongue-work from the Princess of Love.”

Out of fear of more punishment, Cadance obliged, throwing her all into the combined oral cleaning and pleasure of the changeling’s rear. She worked with gusto, twirling and flicking her tongue on all of the sensitive parts of the marehood against her face.

“Mmmm, that feels pretty good, Cady,” Twilight goaded. “Have you been practicing?” An arrogant huff against her lower lips was all she got in reply. “Does Shining know?” she teased with a sick grin. To her disappointment, Cadance refused to dignify the remark with a response.

With a sigh, Twilight pushed her rear back up against the alicorn’s face. “Why don’t you try going a little higher, hm?” the changeling encouraged and waved her thin tail in the air to entice the princess currently slurping at her cunt.

Having learned not to argue back, Cadance conceded to the rimjob and slowly circled her tongue out of Twilight’s vulva and up towards the dark black pucker of her anus. It was only then that she remembered just how filthy the changeling’s plot was, and her tongue recoiled as a disgusting, bitter taste swept over her taste buds.

Twilight quickly lit her horn and firmly pressed Cadance’s muzzle in between her cheeks before the alicorn even had the chance to pull away. “Mmmm, that’s the stuff. Keep licking you brown-nosing slut!”

Reluctantly, Cadance took a few moments to steady herself and then extended her tongue back out. The oral organ dug through the dry filth that clung to Twilight’s ass, scraping the crusty shit off and moistening it back up with her tongue. Twilight sighed in pleasure at the oral attention to her anus, flexing it back against the pink alicorn’s mouth.

It took a lot of Cadance’s willpower not to gag at the foul taste of stale changeling scat, and she powered through the dirty rimjob lest she incur more of Twilight’s annoyance. Twilight continued to push her ass back into her face, and the motion encouraged Cadance to press her tongue more firmly into the puckered hole, nearly slipping inside.

A sudden flex of the dirty anus let a wet, sputtering fart slip out, right into Cadance’s face. The alicorn cringed away as much as she could, but had no choice but to breathe the foul fumes in. “Sorry about that,” Twilight apologized sarcastically. “Must have been something I ate.”

Cadance’s tongue was back on the pucker in no time as her head was practically shoved against the dark anus. Twilight was winking her hole frequently now, as if begging for Cadance’s tongue to slip deep inside of her rectum. Instead, Cadance began to run lazy circles around the wrinkled outer edge.

And then, Cadance saw the butthole flex a few times before a silent burst of air blew out against her face. Twilight grunted, and then pushed with all of her force, and the alicorn behind her had no time at all to prepare herself or react to what was about to come as the head of a thick turd slid out of the wrinkled hole.

A grotesque, bitter taste flooded into Cadance’s mouth as Twilight deposited a load of horseapples directly into her open maw. The princess of love forced herself not to gag on the disgusting flavor as she tried to desperately pull away. But Twilight’s magic held her head steady as another log began to squeeze its way out of her dark anus.

As her mouth began to fill up, Cadance realized that unless she wanted to choke on the fecal fudge, she would need to start breaking it down. Reluctantly, the alicorn forced her teeth together and began to chew into the poop.

Even more potent, stronger flavors burst into her mouth from the mushy waste. An intense sour, slightly spicy taste dominated her taste buds, and she was unable to hold back her gagging this time. A glob of shit spilled out of her mouth with her retching and the half-chewed paste smeared down her pink coat before falling to the floor between her legs with a dull, wet plop.

“Oh no, that won’t do at all,” Twilight tutted as she watched Cadance fight to keep the contents of her stomach down. “You have to eat all of it.” Her magic grabbed onto the fallen lump of horse shit and levitated it back up into Cadance’s mouth. She pushed it into the already full orifice, cramming the waste down into the back of her throat.

It was all too much for the alicorn to handle.

With a muffled cough, all of Twilight's shit was pushed out of Cadance’s mouth and throat. The half-chewed muck pressed right back up against the changeling’s ass, smearing across her pucker, pussy, and upper thighs. A gush of hot bile followed it, splattering against the already filthy ass. Thankfully (or unfortunately, in Twilight’s opinion), there was barely anything in Cadance’s stomach for her to expel, and her gagging was limited to just the scat and a few spurts of bile.

“Hmmm, well I suppose that not everypony can get it on their first try,” Twilight hummed in annoyance. “That just means that I’ll have to train you more. In the meantime though…” she pushed her filthy ass back against Cadance’s face. “Clean up the mess you made.”

Still not fully recovered from having Twilight’s shit shoved down then back up her throat, Cadance was reluctant to voluntarily taste her poop again. But, she also figured that she didn’t have much choice in the matter.

Her tongue darted out, scraping through the thick muck that coated Twilight’s ass. She scraped globs of the nasty scat off of the wrinkled flesh, choking it down the best she could. After a few tries, the pink mare fell into a steady rhythm of orally cleaning the changeling ass.

Twilight could fix that. She let go of her grip on Cadance’s mane and instead summoned a magical horsecock - a glowing purple phallus that hung, suspended in the air. Without any ceremony whatsoever, Twilight hovered it down and placed it’s tip right against the alicorn’s own anus.

Cadance screamed out a strangled moan as the arcane apparition speared her asshole, stretching her wide as it filled her to the brim. It started pumping in and out immediately, and the force of the penetration rocked Cadance’s body and pushed her against Twilight’s messy rear.

The alicorn’s tongue lolled out of her mouth, scooping up more and more of the disgusting scat as she was ruthlessly fucked from behind with the magical horsecock. She was very quickly approaching the edge, and in record time too. She pushed away the odd, nagging thought that this would be one of the quickest orgasms of her life, and that some small part of her was sure to look back on the moment with some amount of lust. Instead, she focused all of her effort on trying to stall her inevitable defeat, (or perhaps, in the deep, dark recesses of her mind, prolong the strange feelings of pleasure she was experiencing).

It was a humiliating sensation, trying not to give in to the nonconsensual pleasure she was being subjected to. But it was pleasure nonetheless, and as Twilight continued to brutalize her ass with no relent, it was futile for her to continue fighting the sensation.

Against her will, Cadance came. A muffled moan escaped her mouth as her entire body shuddered. A gush of marecum exploded out of her used cunt and squirted across the stone floor of the cave with a wet splash.

Twilight continued to pound her throughout her orgasm, not letting up even as Cadance started to spasm from overstimulation.

“P-please T-twilight…” Cadance half muttered half moaned into the filthy muck against her face. “I… I can’t t-take any moooooore…” Her protesting trailed off into a drawn-out moan as Twilight suddenly slammed home into her ass, burying all two feet of the magical cock deep into her bowels.

Cadance had never felt so full in her life. Some amount of magical stretching had to be going on to accommodate the length currently buried inside of her. There was no way that Twilight could be plunging this deep inside of her without doing major damage.

And when the relent finally came, a new, even more humiliating issue arose.

Twilight dissipated the magical horsecock in her ass - she didn’t pull it out. The sudden void in her rectum forced Cadance’s colon to start moving, her muscles fucking on an obstruction that was no longer there.

The alicorn was pretty much helpless as her ass started to dump out a pile of horseapples right onto the floor. Her stretched pucker was useless in trying to stop any of the poop from sliding out of her gaped ass, and her body had still not caught up to the fact that her ass was empty. Gross, wet squelches and farts airly hissed out of her ass as she continued to hopelessly shit out any and all of the crap that had been inside of her.

With a satisfied smirk, Twilight stepped away from Cadance and watched as the alicorn’s upper body collapsed down onto the stone floor. Her pink ass was still help up in the air by shaking rear legs as she continued to slowly push out log after log of thick, solid shit. Twilight stepped around to get a better view, only just barely resisting the urge to lean in and take a bite. She was sure it wouldn’t taste as good as Chrysalis’ anyways.

“How undignified of Equestrian royalty,” the new changeling mused. “But I suppose I shouldn’t complain when I have the privilege of such a spectacular and debaucherous view.” Her temptation did get the better of her then, as she leaned in and gave Cadance’s dirty pucker a firm lick, catching the head of another, final turd before it crackled out and fell to the floor with a dull thud.

With her impromptu bowel movement finished, Cadance’s rear legs finally gave out and crumbled under the weight of her voluptuous ass. Twilight continued to pace around the fallen mare, looking down at the mess of a pony she had created.

“I really do hope you enjoyed this experience,” she said softly, leaning down to speak directly into Cadance’s ear. “Because it is your new reality. Every day, you will service me and you will service this hive. And I would hate for you to not thoroughly enjoy this unique pleasure.”

Twilight stood back up with an evil grin. “But, who knows what the future really holds?” she taunted. “Maybe one day, you too will have the honor of transforming into a changeling, just as I have.”

The cackling evil laughter echoed in Cadance's ears long after Twilight left. She was in shock at what had just occurred, and not at all prepared for the number of changeling drones that seemed to just appear out of the dark edges of the room. They steadily approached her with their long, hard throbbing cocks dangling beneath their bellies, ready to be used on her.

Cadance knew in that moment exactly what her future held, and the uneasy feeling of curiosity at what was about to occur frightened her even more than the disgusting, brutal sex she was about to have.
