Rainbow Dash was sitting within her cloud home, warm and cozy on her couch. It was another late night for the weather ponies, and the soft, gentle feeling of her cloud-made furniture was more than welcome as a good end to a busy day. A pleasurable tingle washed into her when she stretched her tense wings out.

Eventually she settled back into her half-sitting, half-lying position. She reached down beside the couch and took a fairly generously sized book into her hoof, lifting it into her view. A content smile spread over her face as she read the cover; "Daring Do and the Golden Feather," one of the newest, rarest additions to the series that she totally didn't blackmail Twilight into giving her first dibs for.

Rainbow was just reaching the end of the proglogue when there was a knock on the door. Not bothering to hold in her disappointed sigh, she dragged herself over.

Who the hay would be bothering me at this time of night? She rolled her eyes. If it's Fluttershy wanting more cuddles.. She stopped in her tracks, thinking about that. I guess I'd be cool with that.

But when she swung the door open, Rainbow didn't see her adorable yellow pegasus-pal, nor did she see a purple bookworm unicorn. In fact, the thing she saw was so far less than any pony she'd ever known, she closed the door and turned away from it as soon as she saw it.

A recognizably masculine voice came muffled from behind the door. "C'mon, Dash, don't be a dweeb! I just wanna talk for a sec."

Annoyance filled Rainbow's tone. "Get out of here, Gilda. I don't need friends like you."

Gilda pushed the door open, glaring at Rainbow Dash. "Is that how it is? You're just gonna leave your old, awesome friends behind for your new dweebish ones!? After all that I've done for you!?"

Rainbow turned around, shouting. "All you've done for me? Gilda, you've hardly done anything for me, and what you have done has gotten me into trouble!"

Stopping to think about that, Gilda shook her head. "Don't you remember back in Junior Speedsters? You were getting bullied all the time, and I stood up for you!"

With a snort, Rainbow rolled her eyes. "You only helped once! Then you asked to keep the lunch money they stole for me! When things were actually bad, I saw you bucking watching it all happen!"

Gilda looked offended. "That didn't happen!"

--- Some Years Ago ---

It was the final week that Junior Speedster's Flight Camp would be open before fillies returned to school. Rainbow Dash sat on the bottom bunk, the top of which belonged to her new griffon friend, Gilda. She did nothing but sit on her bed, thinking about the bullies that had been welcomed into the camp. She sighed. "You'd think being a blank flank didn't matter for somepony as awesome as me."

Gilda peeked her head down and smiled surprisingly sweetly at Rainbow. "Aww, don't worry about them! They wouldn't know awesome if it bit them on the flank!"

"You're acting cheerier than usual.. is something up?" Rainbow's voice squeaked. Her question earned a nervous chuckle from Gilda.

"Hehehe.. don't I always act this way?" She looked around, as if making sure there was no one watching. "Okay, you caught me, I need a few extra bits." She pouted a little. "Please?"

Rainbow rolled her eyes, unable to help smiling. "Alright," she decided, "my saddlebag is outside. You wanna go get it for me?" Turning her head to look at Gilda, she saw nothing but empty space. Above her, a faint snoring was audible. She face-hoofed in frustration. "Dumb gryphon falls asleep faster than anything I've ever seen..!"

A hop, skip, jump, and a few pegasus-wing-flaps later, Rainbow was walking out of the tent she shared with her group, most of which was out doing flying exercises. Gilda and Rainbow Dash were both exempted from the exercise program due to their natural abilities. Well, and the fact Gilda's a gryphon and their wings are strong enough to do all kinds of things with no exercise or warm-ups at all. Rainbow was the one with true, natural-born talent.

The campfire site was a tiny distance away from their tent, which is why Rainbow felt comfortable leaving her saddlebags there when she didn't need them. She could easily hear anypony in the general area, and if she couldn't, Gilda definitely could. She approached her bag and picked it up, when two voices suddenly right next to her made her jump in surprise.

"Hey there, Rainbow Crash!!" Rainbow felt her IQ dropping just from how obnoxious the voice sounded.

"Heheh, yeah, Rainbow Crash!" The other echoed. It was deeper, stupider, and somehow even more obnoxious. Rainbow felt like her mind was vomiting.

"That's a nice bag, Rainbow Crash!" The colt walked around and grabbed her saddle bag. She yelped.

"H-Hey, that's mine..! Buck off, you losers!"

"Sorry, it's a nice bag, Rainbow Crash!" The other colt echoed yet again, clearly completely following the first colt's lead. "That means it belongs to us!"

"I said give it back!!" Rainbow lunged at the two bullies, but they both stepped aside, causing her to hit the ground with a painful whack followed by several less-than-desired somersaults. Her back smacked into a tree, effectively stopping her momentum while also sending jolts of pain through several parts of her body. Dizzy, she sat upside-down with her back against the tree for what seemed like several minutes.

She spat, trying her hardest to regain her thoughts through the agonizing pain. Had the two flankfaces moved a half-second later, she would have knocked them both out. As she was about to get on her hooves, her vision was blocked by two large hills with a crevice in the center. Two plump, round things sat in a sack of similar color to the hills, and a slightly darker, winking donut sat in the northern area of the crevice. It only took Rainbow a few seconds to realize she was staring right at the plot of one of the colts.

At the descent of the entire structure, Rainbow's world was thrust into musky, smelly suffocation. A scent that could only be properly described as ass stung her nostrils. Laughter erupted from outside of her filthy hell.

"That's a nice look for you, Rainbow Crash!"

"Yeah! Nice look, Rainbow Crash!"

The echo in the area was starting to get on her nerves. There was nothing at all she could do about it, though, with her face stuck in this flankface's flank. She struggled and grunted, desperately trying to get out of her prison, but her efforts were fruitless. Her captors must have been at least four years older than her, which resulted in her being easily overpowered. All she could do was groan and cry out as loud as she could until somepony arrived to save the day.

Unfortunately, though, her screaming stopped when the colt on top of her shuffled his position a little. Eventually, when he settled his full weight back onto her muzzle, she felt that puckered hole enter her mouth, the colt's slightly fatty flanks sealing off any exit. Able to now taste the colt's disgusting plothole musk, Rainbow now struggled more and more violently, but still had no luck.

Finally tired of Rainbow's attempts to flee, the colt grunted. She heard a small murmur come from inside of the stallion's lower belly, before a grotesque gas began to quickly fill her mouth. Rainbow found herself dry heaving. To her dismay, this only resulted in the inadvertent stimulation of the colt's anus. More torturous gas flew into her mouth; the vibrations of the colt's flatulence shook her face uncomfortably. She wanted to vomit, or at least get some fresh air, but the colt's rump remained firmly planted on her muzzle, keeping her in place.

It was about this time that the colt felt a solid, discomforting feeling in his gut. "Hey, Rainbow Crash, did you know that if you eat from stronger ponies, you can absorb some of their strength?" The other colt smirked, quickly understanding his friend's intentions. "Well, eat up!"

Rainbow didn't predict the colt's actions as well as his friend did, and thus didn't expect it when a slimy, bitter mass pressed into her mouth and against her tongue. The flavor immediately cut away at her every sense. Tears welled up in her eyes, but she hadn't the strength to fight anymore. She felt the waste slide down her tongue, covering it in vile residue. All the while, the massive log the colt was producing was still attached to his tailhole, and he was still pushing more fresh, warm-hot manure out.

All of the scat settled down into her throat, quickly forming a round lump that stuck to the walls of her esophagus. She would have given anything to spit it out at that point and eat a pound of dirt, but had no choice but to keep it in her throat where eventually her reflexes forced her to swallow the entire serving.

Even after swallowing, however, the fumes of the shit attacked Rainbow's sinuses, keeping her trying to vomit. She held it back, though, knowing that if she did vomit it would just be pushed back down her gullet by the ass blocking her exit. The colt's flank on her face was a problem, too.

After what felt to Rainbow like many hours, the colt cut another thick, heavy gas pocket into her mouth before standing up. As the colt stood, Rainbow noticed a fairly large creature standing at the doorway to her tent. There Gilda stood, watching the entire event go down without a word of protest. The poor, abused filly was about to call out to her gryphon friend when her mouth was filled with a meaty, thick rod. A salty, sweet-yet-sour juice dropped onto her tongue from the tip of the rod, which she quickly recognized as colt-number-one's rock-hard member.

She obviously considered biting down on the stallion's private weak point, but she knew the result would only be further, more cruel treatment. The colt worked his dick deeper into her mouth until he was content with the depth. Rainbow could feel the tip poking against the the back of her throat.

His hooves held on the back of her head to keep her in place, the colt began to urinate directly down Rainbow's throat, causing chokes and gags to come from the violated pegasus. The warm fluid flowed down her throat with little resistance, and came to a stop pretty quickly, to Rainbow's luck.

Soon, he pulled out of Rainbow's mouth and wiped his lubricated stallionhood all over her face, giving it a thin layer of her own saliva and his piss. The first colt turned and looked back at the second. "You wanna use her?" A gleeful smile answered his question. However, when the two colts turned and looked back at the tree where Rainbow dash was pinned, they found that she was nowhere to be found.

"Buck it!" The first colt yelled, galloping in a hurry around the area to search for the filly.

"Her bag is gone, too." The second observed.

Meanwhile, a safe distance away, the rainbow-maned filly sat atop a tree, saddlebag in hoof. She sniffled, shaking her head.

"They raped me..! And she just stood there..!" Rainbow Dash couldn't believe her friend's negligence, despite seeing it with her own eyes. What kind of friend would just stand there and watch as you got forced down and used as a toilet by two bullies? Rainbow could accept pretty easily what had happened to her; those colts were flankholes, and she knew for a fact that she was better than them. But the disloyalty of Gilda didn't sit right in her head.

She lifted her saddlebag up to her face and screamed into it, using it as a pillow to muffle the sound; the last thing she needed at all was the colts to find her again. She wailed for a long time, the moon starting to disappear at the horizon for its place to be taken at the sun.

Rainbow glared at her hooves, running the moment she saw Gilda standing there run through her mind over and over. "I'm never talking to you again.."

--- Present Day ---

Gilda scratched her head with her talon. "I didn't even think you remembered that.. and I thought you got over it! You said you forgave me!"

Rainbow Dash sighed. "Gilda, my best friend stood there and watched me get raped and shat on, and you expect it to be as simple as forgiveness!? Are you that stupid!?"

Gilda looked off to the side, blushing. "No, I hoped you were." The truth was, she had a personal reason for not helping her friend out of the complicated situation. She couldn't deny that watching the attractive mare get forced to eat and drink that young stallion's waste contents got her.. hot. Not with embarrassment, and not with anger, but a heat so much deeper and more pleasant that she found herself frozen when she saw what was going on. Even to that day, she remembered the whole scene.. she made it top priority for a week to memorize every detail she'd witnessed. "Are you gonna let me talk to you or not!?"

Rainbow shook her head stubbornly, and Gilda knew from the look in her eyes that she wouldn't be getting a moment more of her time. An exasperated sigh escaped her lips as she made made her way back toward the door. However, she was surprised when Rainbow Dash flew ahead of her and closed it, locking it.

"What are you doing, dweeb? I thought you wanted me gone?" Gilda questioned, starting to get frustrated at the situation.

"I didn't say that.." Rainbow scuffled her hoof, looking off to the side in a shy, cute manner, as if to distract GIlda. Then, without warning, hooves went flying. The pegasus's stronger-than-the-average-mare collided with Gilda's face twice in quick succession, causing the gryphon to yeild and fall onto her back due to the mix of surprise and pain. Rainbow Dash lept onto her, pinning all of her limbs with surprising strength.

"Let me go..!"

"Not until you went through what I went through." Rainbow spat in Gilda's face, making her cough and sputter. "And a hell of a lot worse." Trying to look back into Rainbow's eyes, Gilda was met with the forehoof again. This time, the collision made her vision fade to black.

Punishment

View Online

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.

If Twilight had any complaints about her captivity, it’d be that ponies didn’t have to use the bathroom often enough. She’d been alone for at least seven hours at this point and still nopony came in to use her.

If she had anything else to complain about, it was that she wasn’t even in her own body. The furrier, or featherier nature of gryphons was proving to be really bad as far as comfort went. She constantly found herself having itches she couldn’t scratch.

Oddly enough, those were her only two issues with her imprisonment. If she desperately needed out, Gilda was just outside in her real body, “keeping an eye” on her (napping). The meals didn’t always taste the best, and she would have killed for a pillow, but her weeklong stay as a toilet was proving to be rather luxurious.

In truth, she loved when she was used. It took her a few feedings to realize it, but she wouldn’t have minded staying this way for months if it meant she got to bottom-feed from her friends every time they needed to relieve themselves.

What was odd to Twilight was that two of her friends still hadn’t used her. Fluttershy, she understood, because the pony is so shy and kind that doing such a thing to another living creature wouldn’t feel right at all to her. Rainbow Dash, however, was the only responsible for Gilda being locked down in the first place; turning her into a toilet was her idea. To not use her after arranging all of this was unusual, especially for Rainbow.

Twilight let out a sigh, staring up into the darkness hanging above from the ceiling. All she could do was wait. She’d already tried several samples of scat from four different sources, one of which even technically included herself. Her conclusion thus far was that bodily waste is, indeed, enough to live off of for small periods of time; she estimated from the weight she was losing that one could last four to five weeks with such a diet. However, this research had an unexpected variable in it; at the moment, she was a gryphon, and it would be impossible to test it on a pony while she was, indeed, a gryphon.

In other words? Once she got in her body again, she would have to do this all over again. Another week. More scat.

She wouldn’t have it any other way, either.

---

Twilight awoke from her sleep to see a familiar yellow face in front of hers. Fortunately, to not blow her cover, she’d forced herself into the habit of not speaking unless it was absolutely necessary; and in those situations that it was, she would attempt to remain in-character. As such, she stared into the green eyes inspecting her every blink.

“Umm… do you maybe w-want to um… be free…?”

Twilight wasn’t surprised the mare would attempt to come to her rescue. She nodded, staring into Fluttershy’s eyes. She’d already reached her conclusion and there was truly no need for her to continue the experiment as she had already seen major flaws in it, one of which being it didn’t even apply to the appropriate species.

A sigh of relief passed Twilight’s lips as Fluttershy moved back and seemed to play with the binds… until Fluttershy couldn’t help but allow a smirk to cross her lips. Then a giggle. Then a laugh. Then what could only be described as crazed, violent cackling.

Then, her cackling stopped. An eerie quiet surrounded Twilight, and she started to struggle, wondering if Fluttershy had succeeded in freeing her. Nope.

“Do you really think I would let you go?”

The voice coming from Fluttershy’s mouth didn’t sound like her own. No, it was her voice; but it wasn’t the Fluttershy she was used to.

“After all those mean things that you said to me? You think I’d be the one to come and save you!? Even I can’t tolerate a worthless meanie like you!”

Definitely not the Fluttershy she was used to.

The enraged mare hovered her plot over Twilight’s face, her tail twitching and lifting slightly.

“I bet you thought that I wasn’t going to do this, that I was too shy or too weak to come and give you the treatment you deserve… well I’ve got news for you!”

The “news” came out as a high-pitched squeak from Fluttershy’s rear end. It took a graceful moment to settle and rush into Twilight’s senses…

...Twilight began to gag and choke forcefully, desperately wanting to get away from Fluttershy’s ass. This wish obviously wasn’t granted as Fluttershy lowered her plot and sat on top of Twilight’s face. Another small pocket of gas escaped, this time muffled by Twilight’s beak.

The scent was far more dreadful than anything Twilight had the misfortune of smelling in her entire life. She’d personally concocted a potion designed to be the stinkiest thing in the entirety of Equestria, setting two records in the process… Fluttershy’s ass could have broken both of those records, and many more.

“Um… excuse me…” Fluttershy giggled, wriggling her plot on Twilight’s face and working the disgusting scent further into her. Twilight made a mental note to tell Gilda to take several showers once they returned to their original bodies.

Twilight was going to name a tier of foulness after Fluttershy, and it would definitely be the highest tier of anything Equestria had ever known before. The horrid stench of whatever indescribable horrors once occurred within Fluttershy’s stomach were so bad that Twilight instinctually attempted to use magic to cleanse the air around her… which would have worked, had she actually been able to use her magic.

Instead, she was forced to lie beneath Fluttershy and inhale every molecule of the pegasus’s toxic gas. It was only natural at this point she’d dread the next part, which she knew was coming; it was obvious to her that Fluttershy had altered her diet over the past few days just to ensure this moment was absolute hell for her. However, as expected, Twilight’s nethers didn’t quite agree with her mind, enjoying the situation for every little thing it was.

Fluttershy grunted again above Twilight, spraying out more fumes all over the poor gryphon’s face. A moist, crack-like sound followed the gaseous release, as Fluttershy moved the solid, snake-like matter through her bowels. In only a few seconds, it was visible to Twilight.

Sending a rather fast prayer to Celestia begging the substance to not be nearly as foul as Fluttershy’s gas, then proceeding to hate herself for possibly revealing to Celestia she’d gotten herself into this embarrassing situation intentionally (and was even enjoying it), Twilight slowly opened her mouth to catch the thin, smooth treat. Not to her surprise, Fluttershy’s scat was just as, if not more foul than the intestinal air she was breathing before. In fact, as Twilight felt the mass of waste in her mouth, she was so intently focused on the terrible flavour that she forgot to breathe at all.

Fluttershy’s tailhole twitched and contracted several times, before forcing another fresh and warm helping of disgustilicious manure into Twilight’s mouth; intense, conflicting flavors all burnt at her tastebuds as the shit rested on her tongue. Bitter, sour, sweet, foul, and overall cripplingly vile waste.

Twilight had a lot of trouble getting Fluttershy’s waste down, but eventually did pull it off. Chewing was a decision that cursed Twilight just as much as it aided her. It helped the waste slide down her throat faster and get the bulk of it out of her mouth, but the flavors released by chewing were far worse than she would have liked to deal with, plus much of it got stuck in her teeth. Not chewing didn’t release those flavors, but a lot of Fluttershy’s waste would stick to her throat as it slide down, where she’d feel it and taste it for hours more.

The pegasus’ shit, though potent, lacked volume. Only two servings later, less than a mouthful for Twilight, Fluttershy was done and let her tail fall back into its proper position. She hesitated before standing up.

“A-And um… you remember that…! I-I’ll be back in here t-to use you again…!”

A moment after Fluttershy got off the table, Twilight heard the door open to let a large amount of light through, then immediately close. She was alone again, with yet another unpleasant taste in her mouth. She could get used to it.

---

It wasn’t long after Fluttershy left that Twilight heard the door being messed with, as if somepony was desperately trying to get in but couldn’t. In fact, it sounded like somepony really, really needed to use a toilet, but their bathroom door just wasn’t cooperating. Something told her that wasn’t too far off from the truth.

A few more seconds of stumbling with the door knob, the door flew open then back shut. In a time that seemed faster than instantaneous, Twilight was beak-deep in her next tormentor. She would have wondered who it was, but it was unnecessary; the speed told her more than enough.

“Alright now, bitch,” Rainbow Dash practically growled above her, though Twilight quickly realized it only sounded that way because of how much she was straining to keep her asshole closed. “I’ve been holding this in - *Hnngh* - way past its due date… Hope you’re ready!” Twilight hoped so, too.

Easily smelling the mixture before it had even escaped Rainbow, Twilight could tell it was either going to be the high point or the low point of her stay as a toilet. On one hoof, she could love every second, and she could find herself sucking at the tasty cyan plot-pucker for another bitter drop. On the other hoof, however, she knew this could be the worst, worst, worst shit in the world. Every strain from Rainbow to fill Twilight’s mouth would result in yet more screams and more squirms, every grunt filling poor Twilight with dread - and, of course, bowel contents.

Faster than she can fly, Rainbow rushed a deluge of utterly disgusting waste downward into Twilight’s mouth. Runnier than any she’d had the displeasure of tasting thus far, Twilight let the brew rest in her for a second before making any full conclusion about how terrible this was going to be.

Her conclusion? This was going to be a nightmare.

Twilight swore she tasted small chunks of… something in Rainbow’s waste that was even worse than the liquid crap covering every tastebud she had, and, she thought, managing to actually be less bearable than the fluid feces was a feat that no taste should ever be able to claim. Indescribably painful waves of disgust put Twilight’s stomach in her throat and tears in her eyes.

Unlike most of the other waste she’d been fed, which was mostly bitter and/or sweet, like chocolate, the river of mud being dispensed into her mouth tasted… like nothing she could ever imagine. She wasn’t even sure how to describe what it tasted like. Not bitter, though bitter, not sour, yet completely sour - the taste of her own breath was enough to push her over the edge. Fluids from deep within Twilight rushed forth up her esophagus and out the other end, seeming to Twilight like they would rather be outside of her than attempt to digest such a wicked substance.

Too bad Rainbow Dash’s ass was in the way. The only relief Twilight got from throwing up was that her vomit tasted far more tolerable than Rainbow’s waste, even once the two were mixed together. She retched and spat it into Rainbow’s plothole, only to have it pressed back into her throat with another hot serving of death. Her relief was short-lived as every taste of vomit in her mouth was washed away, more quickly than it came.

The assault on Twilight’s mouth only stopped long enough for a long and sputtery, wet blast to fill her mouth and nose with the scent of everything rotten in the world. Being forced to inhale it was like being forced to suck year-old broken eggs out of a dead skunk’s ass, or probably worse. Twilight was so distracted by the brutality occurring on her tongue that she didn’t even notice she, at some point, started involuntarily sobbing.

Vomiting again did not give the same results as before, because vomit could not save her senses from the scent and taste of Rainbow Dash’s flatulence. And, without fail, a lot more came.

An onslaught of more shit pressed out with more gas pressed out with more shit pressed out with more gas… Twilight wasn’t sure how any living creature could contain this and remain alive, nor did she know what in the living hell Rainbow could have possibly eaten to cause this kind of violent reaction in her stomach. All she knew was that, for one of the first times since she’d been imprisoned and forced to be the slave of everypony’s asshole, she actually wanted it all to stop. She wanted free. She wanted to get out of her position.

It was far, far too late for that wish to become reality.

Rainbow Dash cried out above her, jolting her out of her self pity to look up at her friend. To add insult to injury (and a lot of already potent insult), Rainbow was rubbing herself between her legs as she squatted on Twilight’s face. No doubt, just another fluid that was intended for stuffing down Twilight’s throat.

Another mouthful of runny disaster splashed into her mouth with a disturbing sludge-sound. By now, Twilight had stopped swallowing, letting it splash all over her face and dye her head a new color. She had to keep her eyes tightly shut, otherwise blindness would have been certain. Her nose burned as her nostrils kept a recurring, fresh coat of excrement.

She was content with her sickening facial, though the scent of waste directly blocking her nose was sensually catastrophic, she couldn’t hope for any better - the only alternative was swallowing the liquid toxic being distributed to her.

Then Rainbow repositioned herself, planting her anus directly against Twilight’s mouth. As she squeezed, Twilight lost the ability to choose - excess drops of it sprayed off in other directions, but the bulk of Rainbow’s shit was shot into her mouth.

“Don’t think… you can get off that easy…!” Rainbow was close. The excitement and kinkiness of effectively vaporizing her ex-friends’ senses of taste and smell with the matter inside of her plot was plenty enough for her to get off to. A cry-moan of pleasure exploded from Rainbow, as well as a powerful blast of shit and just as much gas, filling Twilight’s mouth so much her cheeks hurt from attempting to keep it all contained.

The sweet, no-doubt-far-better-than-the-terrors-within-Twilight’s-mouth fluid silently squirted all over her face and neck, its sweet and spicy scent completely masked by that of Rainbow’s other expulsions. Twilight tasted as much of it as she could, allowing it to create an excellent sauce for her vile dinner.

Rainbow was panting above her, the after-effects of her orgasm apparent within her blissful, flaming expression. As if in estrus, she’d sharply raised her flank as she came, leading Twilight to wonder if that was due to her pleasure or just because she wanted to cover her face in it. Rainbow remained in this position for several minutes longer.

Once her consciousness had fully returned, Rainbow shot Twilight a glance. “Gotta piss too, keep it wide open for me, okay?”

The dominance in her tone seemed to have leaked out, causing her to sound much more casual as she calmly used Twilight’s mouth for relief. Unsurprisingly, Rainbow’s urine was nowhere near as bad as her scat, though it was still at least in her top twenty of most foul things in the world. Flutterfarts were number one.

The room went silent aside from the ever-so-satisfying sound of stream-in-mouth. There was no trouble in drinking every drop Rainbow gave Twilight, and she even went so far as using her piss to clean her mouth of the previous droppings. She quickly found herself aroused with Rainbow’s fit body above her, tail lifted, marehood directly in front of her beak… she’d fantasized the moment in the past, though in slightly different context.

“Wait, are you getting turned on by this?”

Twilight froze as Rainbow stared at the wettening slit between her legs. Silence followed, awkward for Twilight, confused for Rainbow- who, at that same moment, felt her well run dry.

And then, realizing exactly what the arousal meant, Rainbow burst into laughter, practically falling over and slamming her flank on Twilight’s face in the process. Not that she would have minded.

“Y-You…! Y-You’re turned on by this!?” Her laughter intensified. “I just took a dump in your mouth, made you drink my piss, a-and you…” Laughing reduced itself to a few giggles and snickers. Rainbow shook her flank above Twilight’s face. “Maybe we should make this permanent… looks like we both like it!”

Twilight was too humiliated to give any kind of answer or response as Rainbow got off of her and walk out of the room, giggling some more as she walked. It was only a day until she was going to be let free, and then she’d have all she needed to end the experiment and hopefully conduct it again with some ponies with non-toxic asses.

---

The next day came and Twilight was ready to get out. The door opened, causing her to think for a moment that she was going to be used again, but she was quickly relieved to see her own body standing before her. “Hey.”

Twilight sighed, lying her head back and relaxing. “Hey… time for me to be let free, right?” Her furs individually raised as she heard Gilda snicker.

“Free? Not quite!” Gilda hopped onto the table and turned around, letting Twilight take a good look at her own plot for the second time in a week. “I got the others together, and we all agreed since you loved how Dash treated you yesterday, to keep you in here another two weeks! Isn’t that great?”

“W-Wha-” Twilight was interrupted by her very own flank being pushed down on her muzzle.

“Of course, since we all agreed, who am I to go against it? If you did get let go today, I’d have your friends after me! And who wants that?”

Muffled protests were all Twilight could manage before a roaring gust of air forced her into silent submission.

“Looks like your fun is just getting started, Gilda!”
