Upon waking, Gilda knew that she was in a dark room; the metallic scent told her it was probably a cellar of some sort. One thing was for certain: she didn’t like it one bit. Her oldest friend was absolutely pissed at her, which alone was bad enough, but now she was probably going to get raped and brutalized until she died or something worse.

The door into the dark room opened. Gilda was granted a quick glance at the outside world before the door closed once again. The immediately recognizable, pissed off Rainbow Dash walked over to where Gilda lay sprawled out over a table.

“Comfortable, bitch?”

“C’mon, Dash, you don’t gotta do this! We’re in this together, alright? I’ll never let anything like that-“

Gilda was silenced by Rainbow’s hoof, once again, but this time she’d forced it down her throat. “Shut up. I’m not taking excuses from the likes of you.”

Gilda teared up a little, wanting to squirm away, but she was firmly locked into her current position. Rainbow chuckled. “Hope you’re ready for a whole week of suffering... you’re not going to be getting a moment’s rest from us. It’s just a shame that I’ll be the last one using you.”

Gilda’s eyes narrowed as she felt her signature gryphon rage and hatred start to boil up. “Using me!? For what!? Lemme outta here, Dash, or I’ll make you regret it!”

Rainbow Dash only shook her head in response to her ex-friend’s complaining. “Tsk, tsk… c’mon, Gilda, don’t be a little foal about it. Or a little egg. Or hatchling. Whatever your babies are called.”

With that, Rainbow Dash made her way back up to the door. Gilda was once again left alone in the darkness, waiting for whatever punishment was going to be forced upon her. To her surprise, it only took a second or two for another pony to open the door and walk down. She recognized this one too; one of Dash’s dweeb friends. The purple one with the uniquely striped mane.

She found herself moderately attracted to a few of Dash’s dweeb friends, particularly the orange one and the yellow one at whom she screamed last time she visited. Looking back, she did feel a little bad about that one, no matter how dweebish or lame her friends are; that one actually seemed pretty okay. It seemed like she would have submitted if she’d just asked her to, nicely.

The purple unicorn with the stupid striped mane made her way over to Gilda. To Gilda’s surprise, though, she looked around and started whispering into her ear. “I don’t think you want what’s going to happen to you down here, but I’m performing a study on the nutritional value of… what you’re going to be getting fed. I’d much prefer a willing subject and I want to see the experiences first hand, so if you want to, I’ll take your place.”

Every word was like beautiful music to Gilda’s ears. It was all going to work out to everyone’s benefit, hers included, if this unicorn was right. “Yeah? What’s your plan?”

“We switch bodies, until your body is set free… I’ll still have a little bit of my magic to escape and fix myself up if it turns out my studies are fatal, so don’t worry about that,“ she looked around again. “But we have to hurry before any of my friends see us.”

Gilda nodded. From what she could tell, there wasn’t a single downside to the entire plan- she definitely wanted in. “You got it, let’s go.”

With the glow of the unicorn’s horn, she spoke again. “I’m Twilight Sparkle, by the way,” she grunted; obviously the spell was fairly difficult, and Gilda didn’t even know anything about magic. “I don’t think we’ve been properly introduced.”

“Name’s Gilda. Well, I guess I’ll be Twilight Sparkle in a few seconds,” she chuckled. “Does this mean I’ll technically be helping to punish you?”

Twilight nodded softly, just as her spell finished; a bright, yet controlled light filled the room as Gilda’s vision went black. Next thing she knew, she was staring down at her own body, and she was much shorter than she was used to being. Her body looked back at her, curiously. “Did it work?”

Gilda nodded. “It definitely worked. I think I owe you one, Twilight Sparkle,” she laughed softly. “So, should I head back up?”

Twilight nodded in response. “Just don’t let them get a good look at your eyes…”

Gilda wasn’t sure what she meant until the door opened again. When the light hit Twilight’s eyes just right, she saw that that’s what they were- Twilight Sparkle’s eyes. At least, they were the exact same color. Understanding, Gilda turned away and looked up at the door; there Rainbow stood, looking at her curiously.

“Twilight? Whatcha doin’ down there with the bitch?”

This was just too perfect, Gilda thought. She walked back up the stairs and out the door. “Just making sure she’s comfy~”

Rainbow knew something was up immediately, but shrugged it off. Things often seemed off to her even when they weren’t, mostly because she liked when things were just exactly how she wanted them to be. It became second nature for her to ignore her mind’s desires to question things like that.

She turned to her other four friends, who were gathered around the entrance to the cellar she’d borrowed just for the punishment of the gryphon bitch. “From now on, all of your ‘business’ gets done here. Any objections?”

Surprised that even Rarity was content with the idea, Rainbow continued on. “She’s staying here for a week… let’s make it the most uncomfortable, disgusting week any pony or gryphon has ever had to endure.”

Gilda couldn’t help but wince a little bit. This treatment was all originally intended for her. Dash was willingly doing this. She would have been hurt, if she gave a fuck.

But, she did hold some responsibility for Twilight being down there, and she didn’t entirely like the idea of letting her take every last bit of the blame. Even gryphons had hearts, and cared about things. They just didn’t show it. Why should they? They’re awesome. “I’ll stay here and um… watch her.”

Every eye was suddenly on here. She started sweating. Thankfully, Rainbow unwillingly saved her flank by shouting, “Great idea, Twilight! Somepony needs to make sure she’s at least barely alive. We don’t want to kill her.”

The others nodded in approval. It was obvious to Gilda that Twilight was the leader of their little group, with Rainbow Dash seeming to come in at second place. Gilda trotted (God, did that feel weird) over and sat down next to the door.

She was startled to hear the door next to her open up. Somepony was going to use Twilight already. She glanced over and spotted a pink tail; another glance at the other four retreating ponies told her that it was the fluffy-maned one and not the cute yellow one.

When the door closed, she safely muttered to herself, “Twilight’s problem now, not mine.” Deciding to take a nap and try to get used to her new body a little more, Gilda closed her eyes and rested against the wall.

Inside of the cellar, Twilight closed her eyes and thought about getting some much needed rest. This thought was banished, however, when she spotted Pinkie Pie bouncing down the stairs, right toward her. She thought about what Gilda would say in this situation, then decided to just stay quiet throughout most of the week. She had no experience being a bully like Gilda.

Pinkie bounced closer until she was right next to the table, her figure barely visible due to how dark the room was. “Hiya meanie-gryphon! How ya doin’? Oh wait, we’re supposed to be mean to you!” She cleared her throat, reconsidering her words. “Hiya, bitchy bitcherson! How ya doin’?”

Twilight suppressed a smile at her friend’s silliness. She silently stared up into Pinkie’s eyes. Pinkie sighed softly, and then jumped up onto the table. “Open up for me, would ya? Got lots of tasty cake!”

Unable to help herself, Twilight did consider the idea that Pinkie’s excrement could easily taste like cake, what with all the sugary snacks and everything that she eats. She was, though, sorely disappointed when an absolutely foul and stomach-wrenchingly sloppy log was squeezed into her mouth. Quite similar to (extra dense) whipped cream out of a can, Pinkie’s waste found itself rushed out of her backside and inside of Twilight’s beak.

After letting it sit in her mouth for a few seconds to sample the actual taste, Twilight swallowed the feces. It wasn’t much different from how she imagined it. Despite definitely having a foul, bitter flavor at first, Twilight found that, inside, it truly did have the consistency and almost the taste of quadruple-fudge chocolate cake. For a moment, she wondered if it was possible that Pinkie simply shat out chocolate cake that had been caked with fecal matter; but she knew an idea like that was unrealistic (thus, it was probably true).

Pinkie Pie grunted above her. Twilight noticed her unknowing friend’s tail twitching; but instead of something falling from the sky, another fresh helping of scat plopped right into her mouth. The pasty substance stuck to her teeth and the roof of her mouth, causing her to furiously rub her tongue against it in order to relieve the uncomfortable feeling. She noticed, as she did this, a wet feeling between her thighs. Constrained the way she was, there was no hope for her to hide her aroused gryphon slit.

“It’s for science, Twilight,” she repeated in her head, but her body just wouldn’t believe it. More gryphon sex fluids leaked out of her as Pinkie’s filthy, moist plothole was pressed against her beak. A high-pitched squeak shot out of Pinkie’s ass as she released her last present into Twilight’s face: A small, ice cream scented pocket of gas that blew against her mouth.

Pinkie allowed Twilight to stew in her filthy plothole contents for a long moment longer. Despite only being a few minutes, it felt like hours – though, that's not such a bad thing. Upon being forced to inhale one of her best friends’ anal fumes for a significant amount of time, she found the scent was quite enjoyable.

The sweet mare above her snorted and giggled. "Why are you getting wet down there? Maybe Dashie was right: you are a filthy bitch!" Twilight was unable to resist wincing away from the pink mare's harsh words. So much for "Smile, Smile, Smile!"

A hop, skip, and a jump later, Pinkie Pie was staring into Twilight's eyes with strange interest. "Oh, hey Twilight! Whatcha doin' in there? Ooooh! You like eating poop so you took Gilda's place! And I bet she's in your body too!" She snortled more, leaving Twilight utterly confused. "Don't worry! I won't say a word to Dashie! Pinkie promise!"

After a familiar series of gestures, she turned away and departed the room. It was only a few seconds later that Twilight saw her body re-enter the room, looking at her. "So," she couldn't easily recognize her own voice coming from another source. "How do you like my body?" Gilda hesitated slightly. "I swear it's probably more comfortable when you don't have shit being shoved down your gullet by the pound."

Twilight gave her most reassuring smile. "It's actually scrumptious! Or, at least, Pinkie's is," she thought for a second, staring up at the ceiling. "I need to eat a lot more from different sources before I can come to any valid conclusion... for all that I know, Pinkie Pie's feces tasted good because she eats so many sweets."

Suddenly, to the discomfort of Twilight, Gilda began to give her the most mischievous grin she had ever seen. It didn't help at all that it was on her own body - she had no idea she could look so menacing.

"You say you need it from different sources, huh?"

"Well, I-"

What came out of her next was neither squeaks nor moans, but a squawk. Without any warning, she found her beak planted firmly between the legs that used to be her own! The warm and firm, plump cheeks engulfing her face had a musky scent coming from them... but she was completely used to it. Why wouldn't she be used to her own sweat?

However, something she wasn't prepared for, was the flamethrower-like blast of methane that snaked its way deep into her nostrils and into her mouth.

One thing was for certain: there is a reason that anuses are on the opposite side of the body from the nose. When the two meet, the outcome is no less than lethal.

Another blast of the steamy gas slipped its way out of her ass right into her face. The sounds alone were plenty enough to make a pony with excellent manners turn a thousand shades of red, but that was tame compared to the scent and the... feeling.

Twilight decided that something in her diet had to change, and she suddenly felt bad for Spike for being around her so often. The farts assaulting her senses were more vile than the scent of skunk, wet dogs, stallion armpits and Big Macintosh's sweaty balls all combined into one small vial of vomit-inducing perfume. Potency included for added effect.

Gilda grunted above her; Twilight never noticed how cute her little grunts were until then. Then she punished herself slightly for thinking such a self-absorbed thought.

Some more grunts, her plothole twitching and flexing, and it finally released a deluge of muddy excrement directly into her mouth. The most quickly noticeable feature was the texture, rather than the taste; gritty, yet still smooth; rough, yet still soft. It instantly settled into her mouth as she noticed Gilda pushing out more melted horseapples.

Next, she noticed the taste. It was bitter. Very, very, very bitter. The bitterness flooded her entire mouth and all of her senses, making her want to throw up rather violently. She would have, too, if it weren't for Gilda speeding the flow of earthy shit into her face.

And then, all was dark and quiet- or rather, muffled. Twilight thought she may have died due to illness or something, but almost immediately realized that her face was stuck right into the humid source of her sickening meal. Gilda moaned, softly, pressing her rump right against Twilight's face with much force.

A few more soaking pockets of air sprinkled Twilight's face with the last remnants of ass-food, giving her a few extra shit freckles. Gilda didn't let up off her face until she was gasping for air.

"How was that?~"

"I think... I need... More fiber in... My diet..."

Gilda chuckled. "I'd say so. That felt like a river coming out."

Twilight lay sprawled out in her new gryphon form, still tasting her own waste in her mouth. She considered all kinds of escape routes - but in the name of science, she was going to stay put until her life was at risk. She was just testing the strength of the old shackle on her left hind hoof when the door opened.

"Hello, darling," A familiar white unicorn entered. Oddly enough, the idea of Rarity actually using the bathroom didn't fit inside of Twilight's head. She went so far as assuming that Rarity had a spell that allowed her to dispose of bodily waste directly. Yet here she was, ready to unknowingly take her friend and force her excrement down her throat. The idea, to less and less of Twilight's surprise, was getting her hot.

Rarity whimpered a little once she reached the side of Twilight's table, looking off to the side. "Well, I do understand you're in an unpleasant position, but the least - or, most, really - you could afford is to have some decent manners."

Twilight didn't know how to be Gilda, but she knew from stories that "decent manners" wasn't the way to go. So she remained silent.

"Either way, I suppose we both know what I'm here for. Do be a dear and make sure none gets on my coat."

Rarity climbed up onto the table and turned around, getting into the position Twilight knew she'd take. The unicorn's white vulva was completely exposed to her and only an inch away from her beak. Spiked definitely wouldn't have minded being her test subject for this part, Twilight thought.

In truth, Spike wasn't the only one who would have enjoyed this position. Despite knowing what was going to happen to her, Twilight couldn't help but take a few long, big sniffs of Rarity's most feminine parts.

She was, basically, the first one to actually consider Twilight a friend when she first moved to Ponyville so very long ago. There was always feelings that were kept under Twilight's bed, in her pantry, under her socks, anywhere she could keep them hidden from the public eye - feelings for this white unicorn about to take a dump in her face. Twilight was going to share this very intimate moment with Rarity, yet Rarity had no idea that Twilight was actually Twilight.

Life is a pile of horseapples.

Horseapples were, however, not immediately present, as Rarity began to fire a gentle stream of piss directly into Twilight's mouth. She knew she should have expected it, but she was so busy with self-pity that the warm, salty, and more-than-ever bitter taste took her off guard. It was all she could do not to choke and spit the urine back up onto Rarity's flank.

The stream was neat and well-aimed, somehow creating a perfect, thin line in the air. Needless to say, Twilight was impressed - she wondered if she should ask Rarity how she urinates in such an orderly manner when she was back in her own body. Then she thought about that again, and decided it was a bad idea.

The golden fluid (and by golden, to Twilight, it tasted absolutely luxurious) kept filling her mouth after every time that she swallowed. With how soft and excellent the stream was, it was obvious that Rarity could have kept going for any length of time. Twilight even found herself getting tired of swallowing, and so let it fill her mouth and slowly overflow, getting onto her cheeks and her neck.

Eventually the stream lost even more of its force. Twilight felt the last few steamy drops drip into her open mouth, which was still full of Rarity's scrumptious piss. She swallowed again a few more times, savoring her last mouthful as if it were her last breath of oxygen.

Rarity sighed in relief above her, glancing back down at her. "Very good, darling, I didn't feel a drop come back up. Now for the main event!~" Twilight watched in interest as her friend slowly lowered her plot, aligning her slightly puckered hole with her face.

Despite its absolutely clean appearance, Rarity's anus gave off a rather sour scent when up-close. Once again, and hopefully not for the last time in her life, Twilight took eager sniffs of Rarity's rear end. Musky, humid air emanated from the beautiful poop chute, making Twilight's eyes involuntarily water.

Barely noticeable to Twilight was the slow opening of Rarity's plothole, silently shooting a gust of warm air against her beak. Of course, a whiff or two revealed exactly what had just taken place, but the maregryphon was slowly losing her ability to care about the entire situation. She wished her nose loved the abuse as much as her privates did.

Finally, Rarity's asshole expanded, showing to Twilight the solid, steamy matter escaping the mare's bowels. A beautifully feminine grunt came from Rarity as she strained to push the log of shit right into her open mouth. The sides were rather rough; undoubtedly resulting in a small amount of pain for Rarity as she pressed the waste out.

Clearly not caring, Rarity delivered more and more horseapples onto Twilight's tongue. Unlike Pinkie's, the taste of Rarity's excrement tasted almost salty, while still being more bitter than any food bits can buy.

Twilight began to chew the shit, finding the inside to just be the same exact taste, but much, much, much stronger. The vile flavor caused her body to tense and freeze up. It barely phased her when Rarity dropped a log onto her forehead.

Suddenly, Rarity lowered her plot and forced her asshole around Twilight's beak, surprising her and causing her to jolt out of her tastebud-shock. The unicorn grunted once again, only to release a long series of loud, wet farts directly into Twilight's mouth and nose, forcing her to swallow all of the waste in her mouth - while choking and gagging and retching and anything else a pony or gryphon can possibly do in excessive disgusted reflex.

To Twilight's misfortune, Rarity managed to keep the gaseous assault going for a surprisingly extensive period of time. Whenever she thought the mare was done, another sick blast of undescribable ass vapor would force its way into her mouth and nose.

This continued for at least a full minute. Twilight questioned how any part of a mare could possibly hold so much gas within it; she came to the conclusion Rarity is secretly a balloon.

Finally, after three minutes of pure flatulent torture, Rarity's heated emissions stopped. She stood up and left the room without another word (to make Twilight feel more used and abused). The scent of Rarity's gas hung in the air for the rest of the week.

The creaking of the opening door was like a gunshot within the silent chamber Twilight was (willfully) imprisoned in as Applejack entered. Immediately being hit by a foul stench, Applejack raised a hoof to her nose.

"Phew-ee! Ah reckon somepony needs to change up their diet. 'Smells like somethin' crawled in 'em an' died!"

Twilight would have cared, had she been conscious. The sleeping gryphon was getting some well-needed sleep. Being a toilet is pretty rough, after all, especially if you're forbidden regular meals.

Applejack approached the sleeping creature, putting her hoof on its chest; the slow, yet firm breathing revealed her health was in no state of compromise. It also revealed that gryphons sleep quite similarly to rocks; n omatter how much Applejack nudged her, pushed her, poked her, or shook her, the damn gryphon simply wouldn't give her any acknowledgement.

"Alrighty then," She muttered under her breath. "Ya wanna do this the hard way? Ya'll'll wish ya never woke up when ya get a whiff o' this..."

One graceful hop later Applejack was standing over Gilda's body, her tail lifted ever so slightly to not disturb the sleeping gryphon. This was in vain, however, once the horrid scent of sweat and hard work was corrupting and filling the air around the gryphon's face. Twilight awoke with a gag, tearing up a bit.

"Sorry 'bout that, partner," Applejack smirked above her. "Figured I might as well wake ya from your beauty sleep. It ain't doin' ya no good."

With that, an tragically familiar sound erupted from the cheeks in front of Twilight's face. The air dampened and Twilight's feathers seemed to curl up, the potency and volume combined creating a powerful gas only describable as similar to a dragon's.

The fumes burnt within her nostrils and dried her throat (which came as a surprise to Twilight since the emission sounded rather wet). Fortunately, as Applejack began to forcefully grunt and strain above her, no more gas slipped.

"Get to lickin, an' maybe ah won't suffocate you in it when it comes out," Applejack's dominant voice broke the silence. "Sugarcube."

Twilight, not wanting to get herself nor Gilda killed, began to flatten and slap her tongue against Applejack's barely puckered anus. An assortment of salty, bitter tastes violated her mouth, and she couldn't help but notice a few faint brown marks on Applejack's asshole. She wasn't Rarity by any means, but couldn't she at least put more effort into wiping her ass? So it wouldn't be her job to do it for her?

So bitter and sharp was the flavor now stabbing at her tastebuds that Twilight had to stop and pull away just to make sure her mouth didn't commit tongueicide. At the same time, Applejack was feeling content with her rimjob, and so started her work on the entrée.

The puns about horseapples here are so obvious that I will be neglecting them completely for both of our sakes.

A helping of lightly apple-scented brown mush descended from Applejack's plothole and onto Twilight's face, making her wince. Aside from apple, the waste also smelled vile and repulsive, and to Twlight, infinitely arousing.

She wasn't sure at exactly what point she'd come to love this treatment, but being shat on by her best friends was proving to be an extremely rewarding and informational, albeit smelly, experience. Learning the taste of what most consider to be disgusting or sickening was interesting, and the information about scat nutrition Twilight was gaining in the process was definitely going to be written down (with, of course, some details of the most enjoyable parts of her experiment).

More of Applejack's messy manure seemed to melt onto Twilight's face. Her wide open mouth did a fair job of helping the shit slide off of her face and eventually down her throat, though in the end, there wasn't a thing she could do about her face being covered. More weight collected on her face, to the point that, had Twilight not been gluttonously devouring every spoonful of bowel contents she could collect within her, she would have drowned in the feces. In retrospect, Twilight began to wonder if that would have been such a bad fate. Gilda herself sure as buck deserved it.

Another mouthful of Applejack's waste went down Twilight's throat, the texture mostly creamy but gritty if she attempted to work her tongue into it. It was as though her friend was pumping out bitter, sour mud that had been once had apples in them. Horseapples.

Okay, just one.

After yet another serving of atrociously flavored watery mud, Applejack gave Twilight a slow, mildly approving glance.

"Well, seem like yer better at eatin' shit than anypony coulda given ya credit for. How 'bout a shower as a reward?"

In all honesty, Twilight had expected Applejack to unchain her and take her to an actual shower. Ha! Hot, salty fluid, directly from Applejack's urethra began to splash all over Twilight's face, soaking it and seeping into her fur and feathers. The cowpony's still-warm mud slowly broke apart and slid off of Twilight's face alongside her spicy apple cider.

To Twilight's discontent, the stream of urine lasted but a few seconds. Aplejack turned around and stared down into Twilight's eyes, her own narrowing with dominance and pride. Then, in a quick motion that left her temporarily confused, Applejack lowered her plot and wiped her filthied, scat-coated asshole and the area around it directly against and into Twilight's wet gryphonhood.

Content with using the most intimate bits on Gilda's body as toilet paper, Applejack hopped off the table and shot a wink back at Twilight.

"Maybe if ya behave this good with Rainbow, she'll let you out a few hours early."

And then Applejack was gone. Yet another one of Twilight's friends gave her a feeding, a quick word, then left.

Author's Note

This was originally going to be the last of two chapters, but I've decided to stick on two more. Mostly because it would have taken me a while to finish the Rainbow Dash and Fluttershy parts as well as the conclusion, and it's been way too long since I've made any sort of update.

More coming soon! And by soon, I don't mean months this time!
