Rarity sat straight up in bed, her hands trembling as she watched a video playing on her phone for the what must have been the millionth time. She absolutely refused to believe that what she was seeing was real, it just couldn't be. She had to be having a horrible nightmare. But no, as much as she wished for that to be the case, she wasn't dreaming.

Rarity had just been going about her day at home, brainstorming new dress designs for the upcoming fall formal celebration, when her phone buzzed. Initially, she thought it was just going to be a text from one of her friends, but upon checking it, she was surprised to discover that it was actually a text from Sunset Shimmer.

The girl was an infamous bully at school whom, up to this point, Rarity had been very lucky to have very little contact with. She had absolutely no idea how the girl even had her phone number, but right now, that was of very minor concern.

She'd been sent a short video clip, only about a minute long in total. But that was all that was required for Rarity to be sent into a numb shock. In the video, somebody, presumably Sunset Shimmer herself, was holding the camera and appeared to be sneaking around behind a house in the middle of the night. A quick glance towards the structure, in addition to the houses surrounding it, revealed it to be Rarity's home. The camera would pop up under a window or two at first as if searching for something inside the house, but most windows had dark curtains blocking the view inside.

However, at around the 20-second mark, the camera finally found a small opening in one particular window's curtains, a window into Rarity's bedroom. The fashionista herself could be seen strewn out on her bed, almost completely nude save for skimpy black lingerie. Her right hand was moving rapidly up and down between her legs as she repeatedly jammed a long pink equine-shaped dildo into her widely spread pussy. The video had no actual audio to accompany it, but Rarity could visibly see her past self moaning from lust and using her free hand to grope herself. After the longest 30 seconds Rarity had ever experienced, the footage finally faded to black and a couple lines of white text was displayed on the screen.

"If you don't want this video to be seen by everyone in the school, meet me in the girl's bathroom in the west hall at 4:00 P.M. tomorrow. And don't even think of telling anyone about this, or else." Rarity read aloud to herself in a hushed whisper.

She felt so utterly violated. After seeing the video for the first time, Rarity had been tempted to call her friends, the principal, or even the police to ask for help. But she quickly realized that if she were to do that, Sunset would almost certainly find out and post the video before anything could be done. She could only begin to imagine the horrific impact such a video might have on her public image.

Rarity, the school's most popular, hip, and trendy fashionista would be revealed to secretly be some kind of kinky slut with a passion for...the equine. She'd become a laughing stock at school and her reputation would likely be soiled forever! Not to forget, how might her family and friends react to the news?! Would they disown her out of pure disgust?! What if she ended up getting expelled?! Even if the video could potentially be taken down, if there was one thing Rarity had learned from popular fashion celebrity scandals of the past: Once something was on the internet, it was there forever.

It wasn't worth the risk, Rarity had eventually decided. She would just have to give in to Sunset Shimmer's threat and follow through with whatever she might be asked to do. She wasn't sure what horrible thing the bully might have planned, but under no circumstances could she allow that video to ever reach the internet...

"Goodbye, girls!" Rarity called, waving back as she stepped out into the empty school hallway. The fashion club's room door swung shut behind her a moment later.

The west hall of Canterlot High was empty and quiet, with not a soul wandering through it. Classes had already ended for the day, however, many clubs, including Rarity's own, stuck around for a few extra hours. Glancing down at the stylish purple watch she wore around her wrist, she read the time. It was 3:50.

Rarity was wearing her usual school outfit. It was nothing too fancy compared to the kind of outfits she made for special events, but she liked how the ensemble looked on her. The set consisted of a light blue short sleeve shirt, a simple purple skirt, and her favorite pair of purple shoes with white socks. Underneath, she had on one of her many pairs of lacy black panties and a similarly stylized bra.

However, as much as she really liked this old shirt, it was getting a bit too small in recent years. She had put it together during her freshman year of high school and, now a senior, she had outgrown it. It felt tighter than she was used to and the neck opening had been stretched, creating a visible line of cleavage that also hadn't been there just a few years ago. Rarity had been planning on making a new shirt with a similar design that would fit better, but she still felt a pretty strong emotional attachment to the one she had on.

As she walked down the hall, Rarity had her eyes locked on the bathroom doors just up ahead on the right. As far as her friends in the fashion club knew, she was headed home. Approaching the bathroom, she kept glancing over her shoulder, making absolutely sure that she wouldn't be seen entering. With any luck, she could go in, find out what Sunset Shimmer wanted, and be done with all of this mess in less than ten minutes.

Once confident that she was in the clear, Rarity pushed open the girl's bathroom door and quickly stepped inside. She Immediately spun around and shut the door behind her.

"Well, well, well, so you really did show up after all." A cocky voice spoke behind her.

She whirled around to see Sunset Shimmer leaning up against the wall at the far end of the row of bathroom stalls, a smirk on her face. Thankfully, they appeared to be the only ones in the bathroom as every stall door was left wide open. All of them, except the one at very the end.

However, Rarity had little time to contemplate that as almost immediately she was struck by a pungent odor that nearly knocked her down. It was unmistakably shit. She struggled as to not gag from the smell and attempted to keep herself composed as she stepped forward to confront the fire-haired bully.

"I don't know what you could possibly want from me, but I must demand that you destroy that video at once!" Rarity declared.

"Ah, ah, you're not the one who's going to be giving the orders in here Im afraid." Sunset calmly replied before taking out and holding up her phone.

Rarity cringed as she saw the video of her playing on it. however, it quickly became apparent that it was a different one than the one she had been sent in the text. There was even audio. From the other side of the bathroom, she could clearly hear her past self's lustful moans and groans as she pleasured herself. Rarity was tempted to try and run up to snatch the phone away but she lost the will too as one of Sunset's fingers hovered dangerously over a big red button sitting beneath the video which read: 'Post ' in bold letters.

"I convinced one of those dweebs in the computer lab make me up a script so, should I press this button, it'll post this video onto every major porn site on the web. I wouldn't be trying to make any kind of demands in your delicate position."

"W-what do you want from me?! Why are you even doing this?!" Rarity begged. She had barely even seen this girl before now and now it seemed like she had some kind of vendetta.

"The reason why I'm doing this is not important. But as for what I want from you..." She began ominously. "You are going to do everything that I tell you, no matter what."

Rarity felt her heart sink. Sunset Shimmer was known for being one of the most brutal and ruthless bullies that the school had ever seen, and yet somehow she always ended up getting away with it. There were even rumors that some teachers were actually scared of her.

"Go stand over there," Sunset commanded, pointing to the corner of the bathroom by the sinks.

After a bit of hesitation and some silent grumbling, Rarity eventually did as she was told and walked to the corner. Sunset moved quickly past her to the bathroom door, and after slipping out a small key from her pocket, locked the bathroom door with a chilling *Click!*.

"There, now we won't be interrupted," Sunset said, turning back to face Rarity, a janitor's keyring twirling around her index finger.

"Now, go inside that stall," She said, gesturing to the only non-wide-open bathroom stall.

Fiddling her fingers anxiously, Rarity walked slowly over to the cracked open stall door. The stench in the air seemed to get denser as she neared it. Then finally, after a bit of hesitation, she pushed it open. Part of her expected a bucket of red paint or something similar to be suddenly dropped down upon her head as she entered, but no such thing happened.

Instead, as the door swung open, the putrid smell hit her nose like a train, almost knocking Rarity down from just how powerful it was. She steadied herself against the side wall of the stall, suppressing another gag. She was eventually forced to start solely breathing through her mouth as the smell grew too intense to handle. Looking down, Rarity finally spotted the source.

Dark murky brown water filled the toilet bowl, almost going up over the rim. It was slowly swirling around and around, clearly very thoroughly clogged. But Rarity didn't dare attempt to flush it as the contents would almost certainly overflow and make a disgusting mess all over the floor.

"Oops, sorry about that." Sunset snickered, coming up behind her. "I took an absolutely massive shit before you got here and I don't think It went down quite right," Sunset said in a mocking tone, much to Rarity's utter disgust. "Now, get on your knees in front of the toilet" she commanded.

"W-what?! No!" Rarity shouted, immediately thinking of the potential swirly that Sunset might have planned for her. "Who knows what kind of horrible disease I could catch from your-" Rarity suddenly stopped short as she turned and saw Sunset's finger dart towards the post button once again, an angry scowl on her face.

"-Wait! Please don't!" Rarity desperately begged. Sunset's finger only stopped a mere quarter of an inch from the phone's screen.

"On.Your.Knees." Sunset commanded.

With a shaky breath, Rarity pinched her nose with one hand and shielded her mouth with the other. Then slowly, she got down onto her knees, trying her best to avoid even looking at the contents of the toilet. At this level the smell seemed almost lethal, burning the insides of her nose whenever a bit of the air was able to get through. She could hear Sunset entering the stall behind her and then slide the lock on the door.

"Now, you're going to be putting on a little show," Sunset explained, putting a very familiar looking pink phone with butterfly stickers on top of the toilet paper dispenser mounted on the wall to Rarity's left. Sunset angled the phone so that the selfie camera and screen were at about eye level with Rarity. The phone had been put into selfie mode, allowing Rarity to see herself.

"S-show? What do you mean a 'show'?" Rarity said, almost too afraid to ask.

"Well, as our school's number one fashion expert, I figured that you must be capable of looking good in just about anything." She began. Rarity already didn't like where this was headed. "So, why not share your valuable knowledge with the rest of us? Just think of this as a kind of... makeup tutorial."

"A makeup tutorial?! Is that what all of this is about?!" Rarity said in utter disbelief. "You violated my privacy, recording a video of me during my...personal time, just for makeup advice?! I'll have you know that I have already made thousands of makeup tutorials and posted them all online!"

"Oh, trust me, I don't think you've ever done one quite like this," Sunset said ominously. "In this tutorial, you will be showing your audience how to look 'absolutely fabulous'...all while using nothing but the shit in that toilet."

"WHAT?!" Rarity exclaimed in surprise. "I-i absolutely REFUSE to do anything of the sort! What kind of sick person do you think I am?!" She inched away from the toilet, only to bump into Sunset's legs.

"Well, I guess if you're not going to play along, then I suppose you'll have to live with the consequences of your little 'sex tape' getting published for all the world to see," Sunset said, playing said video on her phone once again.

Rarity was about to just ignore Sunset's threats and demand that she be let out anyway... But then she heard her own moans and orgasmic cries. Unlike the version she had been sent, this version of the video sounded like it went on until...the finish.

"Oh YES! Fuck me harder you handsome stallion!" Rarity heard her past self-cry out, reaching climax as she plunged the full length of the horsecock inside herself on final time.

Rarity imagined the video appearing online. She could already see her friend's horrified expressions as they watched it, wondering how they could have ever been friends with such a disgusting sexual deviant. One of her friends, in particular, would probably never let her near her farm ever again. Meaning she would never be able to see him again...

"But, I suppose If you really aren't willing to do what I say, then I guess I have no other choice but to-"

"-Wait!" Rarity shouted, just as Sunset about to press the button again. "I-i...fine...I'll do it." She eventually said in a defeated tone.

With a knowing smirk, Sunset reached down to the phone resting on the toilet paper dispenser and pressed the red 'record' button. Then, with a light bump from one of Sunset's knees, Rarity was edged forwards again, coming right up to the edge of the dirty toilet bowl.

"What do you want me to do first?" Rarity quivered out, trying not to think about what she might have to do.

"Well, why don't you start by washing your face first? Get off all that pesky 'fancy' makeup that you already have on." Sunset suggested, her voice suddenly taking on a strange edge.

"W-wash my face? With what- Mnf!" Rarity started to say, only to be interrupted as Sunset's hand gripped hard onto the back of Rarity's head. Before she could do anything to resist, she was pushed forwards, her face plunging down into the toilet bowl.

Rarity had only just barely been able to close her mouth and eyes in time before her face hit the surface of the swirling brown water. Her arms and legs flailed around in a panic as her face was dunked, trying desperately to pull herself out. Unfortunately, the initial splash made it impossible for her to get a solid grip on the toilet seat.

Finally, after a few terrible seconds, Sunset let up, allowing Rarity to finally rip her head from the toilet. She gasped for air and then promptly descended into a series of rough ragged coughs.

"There we go, now you're all cleaned up," Sunset chuckled.

"H-how- *Cough* -dare you!" Rarity choked out, a long purple lock of her hair laying down flat against her forehead.

"See? Look at how much better you are looking already," Sunset said, pointing to the phone filming her.

Despite her best efforts, Rarity had failed to properly prepare herself for what she saw. Her eyes widened in absolute horror. Her whole face, normally pearly white in color, was now soaking wet and dripping with dirty brown water. Her black mascara was running down from her eyes as if she had just been crying. If all that wasn't bad enough, Rarity felt her heart skip a beat as she noticed a small no-so-liquid brown glob tangled within the front curls of her hair.

"Now, I think you should introduce yourself to the audience," Sunset began. " Just because your face is covered in shitty water doesn't mean you shouldn't at least be polite." She teased.

Rarity quivered as she felt too overwhelmed to even think clearly. "...H-hello there, I'm...R-rarity and today I will be-*gulp*-I will be showing you how to look f-fabulous with...f-feces." She trembled out, falling back on her usual makeup tutorial introduction, while still on the verge of breaking down completely.

"Ah, I like the alliteration, nice touch," Sunset said, seemingly unfazed by any of this. "Now that that's out of the way, why don't you reach down in there and gather up some facial cream."

Arm shaking, Rarity lifted her arm up and hovered it over the toilet bowl. Closing her eyes as to not see what she was about to do, she very slowly lowered her hand down, letting out a sharp yelp as the tips of her fingers made contact with the cold water. She recoiled away from it instinctively, cringing hard.

"Do it!" Sunset commanded.

Steeling herself as best she could, Rarity once again lowered her hand down, until finally, she broke the surface of the water. Relying purely on what her hand felt, she fearfully felt around in the water, though she did not initially feel anything. Then suddenly, something she felt something solid brush past her hand.

"Eep!" Rarity gasped, her other hand clenching down around her knee.

"Oh? You find something down there?" Sunset asked, laughing darkly. A few moments later, Rarity felt something else brush up against her hand, this time on the other side of the bowl.

She couldn't take this anymore, she needed to get this over with, now. With a burst of speed, she splayed out her fingers and plunged her hand deep down into the center of the bowl. Doing her best to ignore what she felt as the water rose up to her mid forearm, Rarity wrapped her fingers around the first solid thing she could find and immediately yanked her hand back out of the water. It splashed everywhere as she did so, speckling the front of her shirt and skirt with droplets of the filthy liquid.

"Wow, you actually got a pretty big piece, nice," Sunset said, sounding impressed. "Didn't think you actually had the guts to do it."

Slowly, Rarity cracked open one of her eyes, daring herself to look at the squishy mass held in her outstretched hand. She cringed hard as she finally saw it. A large chunk of milk-chocolate colored poop was being firmly grasped in her hand. Her fingers had dug deeply into it, making it resemble a wet and soggy chunk of play-dough. Dirty water was dripping down from her hand and running down her arm, threatening to either drip onto her skirt or worse, down her shirt sleeve. But for Rarity, the worst part of it of all...was that the poop was still warm.

"Now, why don't you show the viewers how one properly applies this new brand of facial cream'?" Sunset instructed.

Very carefully, Rarity brought her hand around so that she could face the phone, making sure to keep her shit filled hand at a good distance from the rest of her. She looked around for a place she could put down the thing, wanting to get the disgusting mess out of her hand as soon as physically possible. She reached up, intending to drop it next to the phone that was recording her, only for Sunset to suddenly speak up.

"Sorry, but I'd rather not have either of my phones getting covered in shit, find somewhere else to put it. That is, unless you'd rather to just rub the whole thing into your face?"

Rarity pulled her hand back and instead moved to put the turd on the floor, hoping that it wouldn't end up spreading out and reaching her knees. However, in her desperation to get it out of her hand quickly, her grip loosened for just a fraction of a second. In the midst of moving her hand downwards, the chunk suddenly slipped free from her hand. To Rarity's utmost horror, it fell down towards her chest, and with a wet *Squelch*, plunged right into her exposed cleavage.

As she held back a horrified scream, Sunset instantly descended into a laughing fit behind her. Rarity could feel the wet and sticky mass resting between her soft breasts, smearing and spreading its filth over her clean white skin. Some of it even began dripping down through the crack of her cleavage, eventually making a brown trail down her stomach and staining her shirt from the inside.

In the midst of trying not to completely lose it, Rarity spared a glance back up to her hand, only to find it in a similar state. The palm and insides of her fingers were caked with a thick layer of brown muck that squished and squelched whenever she flexed them.

"Well, it looks like you found the perfect place to keep it. Now, we can get into the really fun stuff." Sunset said, having finally calmed down from laughing. "Go ahead, I think you know what to do with all that shit on your hand. But don't touch the turd stuck between your tits, I'm sure the viewers enjoy the look~."

Slowly calming her shaky nerves, Rarity cautiously began moving her filthy hand closer to her face. Somehow, it seemed like her nose had actually gotten used to the putrid stench as she could no longer smell it anywhere near as strong as before. It was either that or the extreme level of stink had caused her to lose her sense of smell completely. Rarity honestly couldn't tell which possibility was worse.

Her whole body shuddered as her fingers finally made contact with her right cheek, leaving behind a small smear of brown. Shutting her eyes tightly, as to not endure watching herself do the unspeakable, Rarity began cautiously rubbing the sticky mess over her cheek. Rarity tried to imagine that she was anywhere else but here: Doing her makeup at a fancy beach resort, wearing a mud mask at the town spa, anything at all to distract her from the fact that she was currently spreading someone else's shit all over her face.

A few tense and traumatic minutes later, the tense silence only being interrupted by the occasional amused chuckle or two from Sunset Shimmer, the bully spoke again. "There, that ought to be enough of that for now.."

The moment the blessed words reached Rarity's ears, she pulled her hand quickly away from her face. She was almost too scared to open her eyes, but when she finally did, her mind nearly shattered on the spot.

Her once beautiful face was completely covered in filth, to the point where there was barely a part of her complexion left that hadn't been turned some shade of brown. The bridge of her nose had a particularly large glob of shit sitting at the end, having oozed down from her forehead. Rarity felt light-headed and she was trying desperately not to pass out.

'I-it's just a mud mask, that's all, n-nothing more...' Rarity repeatedly told herself, if only to prevent herself from fainting.

"Now, there are just two more things we are going to do for this little tutorial. I know you must be absolutely loving this, but I'm afraid we don't have too much time left before they start cleaning out the bathrooms." Sunset explained though Rarity was far too busy staring blankly at herself on the phone to really pay much attention. "A missing key ring will only delay the janitors for so long."

*Zzziiipp*

The sound of a zipper being yanked down, followed by the rustling of clothing, finally shook rarity out of her trance. She likely would have gasped as she turned to see Sunset suddenly pulling down her jeans, only she was too fearful of allowing any of the poop a chance at finding its way into her mouth.

Jeans falling down around her ankles, Sunset turned away from Rarity. Her panty-clad ass was perfectly at eye-level with the shit-smeared fashionista, and due to their close proximity, she could make out every detail of the girl's posterior. The bully's red panties hugged her ass tightly, partially sinking down between her yellow-orange cheeks.

"Next, we're going to be applying some special perfume~," Sunset said, the tone she took on not exactly filling Rarity with confidence. She wasn't sure how stripping down to her underwear was supposed to help apply perfume of any kind. As it was, Rarity highly doubted any kind of perfume would ever be able to cover the smell likely infused into her skin by now.

It was then that, with Sunset leaning up against the stall door, she bent over slightly, sticking her ass right in Rarity's face. Just as she had finally worked up the courage to speak, it happened.

*Pwwwwfpt!*

"Ah~" Sunset sighed as she blasted Rarity in the face with a warm fart.

Rarity wasn't sure what was worse, the fact that she couldn't even smell the girl's flatulence over the gunk already covering her face or the fact that her eyes and mouth had been wide open at the time. She could almost taste the noxious gas in her mouth, causing her to start gagging and coughing yet again. It was a miracle that she managed not to lose her lunch as of yet.

*Pwwwwfpwarpt!*

Another fart ripped out from between Sunset's clenched ass cheeks, plowing into Rarity's face and even causing her hair to be blown back. The feeling of light-headedness she had been feeling all this time intensified. The realization of what she had already done, the stress of the events that lead up to this moment, everything was hitting her all at once.

"Ough~" Sunset groaned. "Here comes a really big one-"

*Pffwpwparrptlpt-splort!*

A third blast, much more bubbly and wet than the previous was the final straw. After witnessing the formation of a dark brown line along the middle of Sunset's panties, Rarity wobbled on her knees, her eyes rolling upwards. As she collapsed, she fell forwards, her nose speared down right between Sunset's cheeks.

"Oh~? Well, looks like you've finally had enough. I'm genuinely surprised someone like you was even able lasted this long." Sunset said, a shiver running up her spine as she felt the tip of Rarity's nose pressing the wettened fabric of her panties right against her dirty anus. Reaching back she grabbed the back of the fashionista's head with her hand, forcing it further between her cheeks.

"I guess I'll have to do the last step for you." She mumbled, a pleasurable tingling sensation running up her spine. It was then that she felt yet another ball of gas prodding at her anus.

While still holding Rarity's face deep between her cheeks, Sunset braced herself against the stall door and relaxed, intent on giving the girl one last gassing.

*Pfworpt-crackle!*

"Oh, shit~" Sunset gasped, feeling an unexpected bit of solid waste pass through her anus.

Letting go of Rarity's head, the unconscious girl feel to the side, leaning up against the side of the stall. Sunset reached down and felt the seat of her panties. Beyond the smearing from the fashionista's shit face-mask, having pretty much used her as living toilet paper, she could feel a small bulge in the fabric.

"Huh, I thought for sure I was empty after everything I managed to dump into that toilet. Oh well, nothing can be done about it now." She murmured. At least it hadn't been very much, easily coverable by her jeans.

Bending down, she grabbed the hem of her jeans, pulling them back up. "I'll have to get cleaned up at home, It won't be very long until the janitors get here. They probably got another set of keys by now..."

Sunset unlocked and opened the stall door, walking out from the stink box she left Rarity in. Checking in the bathroom mirror, the evidence of her own little accident was pretty much nonexistent. Noticing the sleeping form of the fashionista laying in the stall behind her, Sunset pocketed both her phones.

"Well, for your sake, I should hope you wake up before the janitors get here. I'd hate for all that to have been for nothing." Sunset called back, though she honestly couldn't care less about the girl's precious reputation. Taking her own keys out from her pocket, she walked to the bathroom door.

'And if she thinks I'll just delete these videos, that girl has another think coming...'

Author's Note

A bit more extreme in terms of scat play than I am used to but was fun to write nonetheless. Hope you enjoyed!
