The sirens discover a new type of magic and attempt revenge on Sunset with it.

After the sirens lost their powers, they discover magic stones containing a new type of magic: The power to make someone fart. So naturally their first course of action is to use it to try to take revenge on Sunset Shimmer. Can Sunset's dignity and friendships survive the sirens' stinky revenge plan?

Contains: Farting, with a brief, light scene each of spanking and omorashi and a bit of soap/washing and facesitting. And stretchy scenarios and lower quality. I'd recommend this only to people who either have a fetish for this or find it funny, and don't expect it to be written like a fancy novel.

I have been experiencing writer's block, and in the event I do write something I usually don't feel like posting it anymore. I wrote this some time ago but I only decided to submit it now, usually due to shyness or lower quality than usual. But I was inspired to post this after a talk with the friend I mistakenly thought I lost recently.

It was originally inspired by a dream I had about Sunset farting, and it being caused by some monster with a fart fetish. I remember being shocked we actually hear her fart in the show, and when I woke up, I was all "Of course, I knew they wouldn't have any of them fart onscreen," but it got me thinking about it for days until I wrote this.

Fart Magic

Adagio Dazzle, Aria Blaze, and Sonata Dusk were wandering a cave, a ways outside of the city. They had adjusted to living a life without their siren powers, but hated not being able to control people anymore. The world they had been banished to had gotten ten times worse, and it was all because of Sunset Shimmer. After hearing of more Equestrian magic coming through, they had searched for something, anything, they could use to get their revenge.

Eventually, while exploring a cave, they saw a glowing light, and ran towards it. As they got near, they saw the source of the light: Three glowing stones, nothing like their siren pendants, but definitely magical.

"I wonder what they do," said Adagio, picking up one of the stones.

Aria picked up another. "One way to find out," she said, and she aimed it at Sonata and blasted her with its magic.

...

A few days later, Sunset Shimmer and her friends were having a picnic at the park. Sunset had been exercising a lot lately, leading to more fun times with Rainbow Dash, so Rarity had fashioned a new exercise outfit for her, consisting of a pinkish purple T-shirt and skintight black spandex shorts that went down about a third of the way to the knees.

As the girls were making plans for a big party at Rarity's house tomorrow, the sirens watched from behind a bush. They were each wearing a necklace with a magic stone on it.

"Whatever you do, keep your trap shut," Aria warned Sonata. She knew the silly siren would be tempted to laugh.

Adagio raised her stone, pointed it at Sunset, and cast a small bolt of magic. It hit Sunset directly, though she didn't feel or notice anything. Until a second later.

FFFFFFFFFRRRRRRRRRRRRRT!

All the other girls turned toward Sunset. Sunset blushed and giggled nervously.

Sonata burst out laughing. Adagio and Aria shot her a disapproving look, but luckily for them, their enemies couldn't hear her laughter because Rainbow Dash and Pinkie Pie were laughing louder.

"Sunset!" said Rarity. She sniffed. "Ugh! This is absolutely foul!"

"I'm so sorry," said Sunset, blushing beet red. "I didn't mean to."

Rarity could see how ashamed Sunset was. She remembered the times she'd held it in for hours, and how humiliated she'd have been if she had been unable to in front of her friends. Especially considering how loud her farts were afterwards, once she was alone. "Oh, it's all right. Just... try a little harder to hold it in."

Sunset was relieved that Rarity wasn't holding this against her. Rainbow and Pinkie had stopped laughing, and they continued their conversation from before as though nothing had happened.

"Well, that didn't work," said Sonata.

"I told you one fart wouldn't have much of an effect," said Aria.

"Then let's take the next step," said Adagio, raising her stone. She and Aria had experimented on Sonata with the stones to find out the extent of their powers. Sonata was the only one who wasn't afraid to fart in front of the others, and she found it rather fun. The sirens had discovered that the stones could make a person as gassy as they wanted for as long as they wanted, and had planned to use it to get revenge on Sunset by humiliating her in front of her friends.

Adagio thought, Make her fart for an hour, and zapped Sunset with the stone's magic a second time. If this went according to plan, her friends would be too disgusted with her to go near her again. Except Rainbow Dash and Pinkie Pie, who would never let her forget it.

Sunset groaned.

"You all right, sugarcube?" said Applejack.

"I... think I should step away for a few-"

BBBBBBBBBBBBRRRRRRRRRRT!

This loud, deep-pitched fart was followed by many shorter farts.

Rainbow and Pinkie started to laugh again, as did Sonata from the bushes.

"Stop it," said Applejack. "Can't y'all see how embarrassed she is?" She patted Sunset on the back. "Don't worry your pretty li'l head none. We all fart. It's nothin' to be ashamed of."

Rainbow Dash and Pinkie stopped laughing. They still thought it was funny, but they didn't want to make Sunset more uncomfortable.

"It..." PRRRRRRRT! "won't..." FFFFFRRRRP! "stop!" PPPFFFFT!

"You must've eaten something that didn't agree with you," said Pinkie. "It happens to me all the time! Just wait it out!"

Sunset grunted and let out a longer, wetter fart. "This doesn't seem like it will go away any time soon." She tried her hardest to hold it in, but after about ten seconds, a boisterous wet fart made its way out of her. She sighed. "I'd better go home until this stops. I don't want you to have to put up with this."

"Do let us know when you're feeling better, darling," said Rarity.

...

As Sunset ran home, she farted several times. She'd try to hold it in if she ran by anyone but farted in front of them a few times, causing them to either snicker or shoot her a disgusted look. Once she got home, she lifted her leg and let loose, no longer having to worry about feeling ashamed.

BBBBBBBBBBBRRRRRRRRRRRRAAAAAAAAAAAAAAAAP!

She had to admit the relief felt wonderful, but it didn't last long. Another loud, higher-pitched fart later, she climbed onto her bed. She lay facedown and let out several wet farts. Then she lay on her back and lifted her legs into the air.

PPPPFFFFFFT! BBRRRRRRRT! PPPPPPPPPRRRRRRRRRRRRT!

Her bedroom was starting to smell now, but she didn't mind the smell of her own farts. After laying in this position and farting for five minutes, she positioned herself facedown again with her rear end in the air.

PPPPPPBBBBBBBBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRRRRRT!

A loud, deep-pitched fart made its way out of her, and several more farts came after. Why am I farting so much? Sunset thought. She feared explosive diarrhea or something was coming, but as minutes went by, nothing came out of her behind but farts.

An hour after Adagio had cast her spell, Sunset finally stopped farting. She waited ten minutes to be sure, after which she texted the other girls saying she was better now. They met up again and hung out as though the whole thing never happened.

A Day of Farting

Sunset woke up in the morning. She was looking forward to the big party at Rarity's house today. She was a bit concerned at farting a few times while laying in bed, but this time she wasn't much gassier than any other night. She hoped that what happened yesterday wouldn't happen again.

She changed into her athletic outfit, which she would often wear for a few days before washing them at night. Standing in her shirt and black panties, she sniffed her shorts. They smelled a little, but she had to sniff them point blank to notice. Besides, half the smell was probably from sweating in them. So she put them on and walked out the door, and started jogging.

...

"We need a new revenge plan," said Adagio.

"Here's an idea," said Aria. "We make her fart for a whole day! That will keep her from her friends AND the party they were planning yesterday!"

"No," said Adagio. "If she farts for that long, she'll know something's up. We don't need her on alert."

"I need to go to the bathroom," said Aria, and she walked upstairs.

"Now," said Adagio. "What are your ideas, Sonata?"

Entering her bedroom instead of the bathroom, Aria climbed out her window and ran to Sunset's house. Sunset was on her way back from her run, walking over to her door. Aria held up her stone. Make her fart for 24 hours.

Her stone hit Sunset with its magic, and a few seconds later, Sunset groaned and ran inside. Aria snickered.

...

Once Sunset closed and locked her door behind her, she let loose with several farts. Some high-pitched, some low-pitched, some long, some short, and some wet. All of them loud.

"Not again..." FFFFFFFFFRRRRRRRRRRRT! "Well, the last time subsided, so..." PPPPPPPPPFFFFFFFFT! "...maybe I can wait this out too."

An hour went by. Two hours. Three hours. Sunset did not stop farting.

"If this doesn't stop, I won't be able to make Rarity's party..." PPPPPRRRRRT!

Aria watched from a window and snickered. She continued to keep an eye on Sunset, and whenever Sunset ran to the bathroom, Aria would find a bush to pee behind, keeping her pants dry.

Soon, it was half an hour before Rarity's party.

Please, PLEASE stop farting! A long, wet fart made its way out of her, and she sighed in disappointment. There was no way Sunset could ask her friends to put up with her farts. She could probably fart silently if she really tried, but she'd stink up the place too much, especially for Rarity.

Sunset sent Rarity a text. "I can't come to your party today."

Rarity replied. "Why not, darling?"

Sunset texted back. "That thing that happened yesterday... It's been going on again for hours without end."

There was a pause. Then Rarity's next reply came. "Oh, you poor dear. You shouldn't have to miss a party for that. Come anyway. I'll bring air freshener." Then "But please try to fart silently if you can."

Sunset's heart leapt. She'd get to enjoy the party after all. She hoped Rarity had some strong air freshener. She'd need it.

She practiced farting silently before she made her way to Rarity's house. Aria followed her, unseen. Sunset knocked on Rarity's door, and Rarity opened it.

"Sunset, you'll be pleased to know I sprayed the house with air freshener that will eliminate any foul odors for 24 hours, so you can... do that... all you want. Again, please try to keep it silent."

"I will, and thank you."

Once all the girls arrived they had their fun while Aria watched bitterly from outside. She couldn't believe her plan had backfired. Sunset was really enjoying herself here.

Sunset farted silently most of the time, but occasionally a loud fart would burst out of her. Sunset would blush, and Rainbow and Pinkie laughed a bit, but they made sure she knew it was in good nature, and Sunset felt less ashamed of it, knowing it didn't put her friends off too much.

"Even the humiliation of farting so much is going away," Aria muttered to herself. "None of them, not even Rarity, will ever turn their backs on her."

After another accidental loud fart, Sunset said "It's strange that this should happen to me. I'm usually never this gassy, not even after eating beans. Ponies don't fart any more than humans do."

"They do here," said Applejack.

"I agree that farting for this long is not natural," said Twilight. "I once ate the gassiest foods imaginable - as a test, purely for scientific reasons - and I did not fart non-stop for more than a few hours." She blushed lightly, and continued. "I think magic might be involved."

"Only one way to find out!" said Rainbow Dash. "Let's pony up! It's funny to hear her fart once and a while, but for that long? I won't let her suffer for it!"

Aria gasped. If they ponied up and used their magic, it might destroy her stone, like it did her original pendant. There was nothing for it. Aria raised her stone and lifted her fart spell.

"Wait a minute." Sunset paused, waiting to fart again. "I think it might be done." She waited a whole minute, without farting. "Yes, whatever it was, it's gone now."

"We still get to pony up, right?" said Rainbow Dash.

"There's no need to," said Twilight. "Not unless it happens again."

"I'll need to change my shorts now," said Sunset.

"Oh PLEASE tell me you didn't," said Rarity.

"No, nothing like that. Wait..." Sunset felt her butt. "No. My shorts are a bit damp, but only with sweat. I'm just saying, they must smell like farts now." She blushed lightly.

"Any... volunteers?" said Rarity.

"I'll do it!" Pinkie sniffed the air around Sunset. She sniffed close to her. Nothing. Then she sniffed her butt. "Phew! Yes, your shorts are really stinky, but you have to be right next to them to notice!"

"Must be the air freshener," said Sunset.

"In that case, just enjoy the rest of the party," said Rarity.

...

Aria returned home.

"Where have you been?" said Adagio.

"At the movies," said Aria.

"You went and did it, didn't you?"

"No!"

Adagio raised her stone. "Tell the truth or I'll make you fart in front of Sonata!"

Sonata giggled and watched with excitement.

"Fine," said Aria. "I thought it would ruin her day, but it didn't. Their friendship's too powerful, and so is Rarity's air freshener."

"So after I specifically told you not to, you did it anyway. Did they suspect anything?"

"No." Adagio gave her a glare. "I mean, yes, but I removed the spell as soon as they did so they couldn't pony up!"

Adagio raised her stone and cast a spell on Aria.

FFFFFFFFFFRRRRRRRRRRRRRT!

Aria blushed at the sound that had come out of her while Sonata fell on her back and laughed, kicking her legs in the air.

Aria and Sonata's Failure

A few days later, the sirens were plotting again.

"I wonder whether the stones can make people wet their pants," said Adagio.

"Let me test that," said Aria, and she pointed her stone at Sonata. Make her pee herself!

PPPPPPFFFFFFFFFFFFT!

Sonata giggled. "Nope!"

"If the stones affect the bowels, maybe they can make her mess herself," said Adagio.

Aria chuckled and pointed her stone at Sonata, who looked very nervous. Make her soil herself!

PPPBBBBBBBBBBRRRRRRRRT!

This fart sounded dirtier and wetter, but Sonata felt her butt and giggled. Aria lifted Sonata's skirt to inspect the damage, and was disappointed that there was none.

"So, they can only make people fart," said Adagio. "Hmmmm... I have an idea. But I'll need to stay here and think of a backup plan in case this fails. While I do that, Aria, make Rarity fart while she's hanging out with Rainbow Dash in the woods."

"Ooh, sounds evil," said Aria. "But why Rarity?"

"Because she played a part in our defeat as well, and she'd be the most embarrassed about farting."

"Gotchya!"

"And Sonata, fart in Sunset's face. But no longer than an hour!"

Sonata giggled. "That'll be fun!"

...

As Sonata was walking to Sunset's house, she ran into Pinkie Pie halfway there. Pinkie was wearing a white and pink T-shirt and short, tight jean shorts today.

Ooh! I can make another one of them fart and get revenge on her! Sonata raised her stone. Make her fart for an hour!

Pinkie let out a loud fart, and giggled.

Sonata squealed and ran over to her. "I think farts are funny too!"

Pinkie farted several more times. "Ooh, why am I farting so much?"

"I made you fart with this magic stone!"

"Ooh! We can have so much fun with this!"

"Wanna have a farting contest?"

Pinkie's eyes lit up. "Sounds like fun!"

Sonata immediately cast a fart spell on herself, and she and Pinkie took turns farting, each fart being loud and several seconds long. With each fart the other would laugh hard, accidentally farting a few times, but still have plenty of gas for their turn. Sometimes Sonata would stick her butt out to fart, and her skirt would be blown back by her farts so that her white panties could be seen, causing Pinkie to laugh more. Pinkie was in the lead halfway in after a boisterous 34-second fart that Sonata couldn't top. And after an hour, when they ran out of gas, Sonata cast the spell again!

...

Aria stood by Rarity's house and watched her leave. She followed her to the entrance to the woods, where she met with Rainbow Dash, and they walked in. Aria followed close behind, keeping as quiet as possible.

After a few minutes, Aria raised her stone and pointed it at Rarity. Make her fart now, and then for an hour!

Rainbow Dash turned around and saw Aria. "Rarity look out!"

As Aria shot her magic spell at Rarity, Rainbow Dash pushed her out of the way and was hit by the spell instead. Rainbow farted loudly.

"Shit!" said Aria.

Rainbow Dash and Rarity turned toward Aria.

"What are you doing here?" said Rainbow Dash. She felt a pressure in her bowels. "Oh no... Rarity, you might wanna keep a distance from me."

"Why..."

PPPPPPPFFFFFFFFFRRRRRRRRRT!

Rainbow chuckled. "Excuse me."

"Wait a minute," said Rarity. "That thing with Sunset, then you take a magic spell for me and now you're breaking wind suddenly... You did this, didn't you Aria?"

Aria turned around and ran, but Rainbow caught up to her and tackled her to the ground. Then she sat on Aria's face. Aria let out muffled cries. Rainbow's butt was a little sweaty and smelled slightly, but she knew it was about to get worse.

Rainbow looked up at Rarity, as if asking her approval.

"Oh, go ahead," said Rarity. "You just saved me, and this will teach that ruffian never to try this again."

Rainbow grinned and unleashed a flurry of loud farts on Aria. Many of these were long and/or wet. Aria thrashed her legs, screaming from under Rainbow's tush and trying her hardest to get out, but the farts made her feel nauseated, and she knew Rainbow would be farting for an hour. Eventually, Aria reached her limit, and everything went black.

"Is she all right?" said Rarity.

Rainbow got off Aria and saw her chest moving. "She's fine. She's just unconscious." Rainbow turned Aria over facedown, sat on her butt, and continued to fart on her.

...

Adagio was pacing back and forth. "Where are those two idiots?"

The door opened, and Aria walked in, looking weak and shaking slightly.

"What happened to you?" said Adagio. She walked up to Aria and sniffed. "Ugh, you smell horrible!"

"Rainbow Dash... took hit for Rarity... face-fart..." Aria shuddered.

"You need a bath." Adagio filled the tub with soapy water and threw Aria in fully clothed. As Adagio scrubbed Aria, Sonata ran into the room.

"Guys, the most amazing thing happened!" She noticed Aria, and quickly cast a spell on her. Bubbles appeared in the water around Aria, who blushed lightly but said nothing.

"Lol Aria farted in the tub!" said Sonata.

"So, how did your mission go?" said Adagio.

"It went great! I made Pinkie fart for revenge, but she thinks it's funny like I do, and we had a farting contest! She won, but it was the most fun I've had in EVER!"

"What?" said Adagio. "You were fraternizing with the enemy?"

"They're not that bad," said Sonata. "They forgave Sunset, why won't they forgive us?"

"Get out of here," said Adagio. "I don't want to see you in this house ever again!"

"But..."

"NOW!"

Sonata sighed, packed her things, and walked away.

Once Adagio washed the fart smell off Aria, Aria sat on her bed, still in her wet clothes, with her arms wrapped around her legs. She sat for hours before she eventually got over being farted on. But she didn't want that to ever happen again.

...

Pinkie was at home, enjoying the parting gift Sonata had given her after their farting contest. She had just let out a fart nearly as long as her winning fart in the contest when she heard the doorbell ring. Pinkie answered it. Sonata stood at the door.

"Ooh! Are we having another farting contest?"

"We could. Adagio kicked me out for betraying her."

"Aw, that's too bad. But no problem! You can stay here for now and help out around Sugarcube Corner!"

"Really? Thanks!"

Pinkie lifted her leg and farted loudly. Sonata cast a fart spell on herself...

The Final Plan

Author's Note

In this chapter, Sunset and Twilight are wearing their Legend of Everfree shorts, Sunset's shorts as short and tight as Twilight's. Applejack is wearing short, tight jean shorts. Pinkie Pie is wearing short, skintight teal shorts. Rainbow Dash, Rarity, and Fluttershy are wearing their main outfits. Again, no skirt over Rainbow Dash's shorts.

The Final Plan

"Aria, let's come up with one last revenge plan! Let's put all our effort into this!"

"No thanks," said Aria.

"What?" said Adagio.

"I don't want to get farted on by Rainbow Dash again!" Aria shivered.

"Well, she loves to fart, so we can target everyone BESIDES her! Or Pinkie!"

"I won't take that chance!" Aria threw her stone on the ground and crushed it with her foot.

"You will regret that." Adagio put Aria over her lap and spanked her ten times. Aria winced in pain with each swat and let out a little yelp on the last three. "Now go to your room and don't come out until I get back."

Adagio led Aria to her room and Aria walked inside.

"I have to go to the bathroom," said Aria.

"Like you did after I told you to not make Sunset fart for a day?" said Adagio dubiously.

"I really mean it this time!" Aria held herself. "Can't I pee first?"

"Just hold it," said Adagio, slamming Aria's door and locking it.

Adagio returned to the living room and tried to think of a plan. She decided to make all but Rainbow and Pinkie fart so that they'd make fun of them. It was a longshot, but the best she could think of.

...

The girls were hanging out at the park. Adagio watched from the bushes and raised her stone. Make them fart for an hour! One by one, she cast the fart spell on Fluttershy, Applejack, Rarity, Twilight, and Sunset.

The five of them moaned in discomfort, and as they were starting to fart, Sonata walked by the bush. "Hi Adagio!" she said loudly. The girls turned in her direction, the five gassy ones trying to hold in their farts. Sonata gave Adagio a wedgie and dragged her over to the girls by her white panties. "She cast a spell to make you fart! It's all her fault!" She took Adagio's stone and threw it to Pinkie Pie. "Here, now you can fart all you want!" Sonata cast a fart spell on herself while Pinkie cast it on herself and Rainbow Dash.

"There," said Pinkie. "Now Dashie and I will fart for as long as the others! How long is that exactly?"

"An hour," said Adagio. "Now give me my stone back!"

"How about we fart on her?" said Pinkie.

"That'd be awesome!" said Rainbow Dash.

"Normally I'd be above something so unladylike, but..." Rarity farted loudly again. "My dignity today can't be saved now."

"If you're all doing it, I suppose I can too," said Fluttershy quietly, letting out a silent fart. "I just hope she'll be all right after this."

"She'll be fine," said Rainbow Dash. "She'll just faint, smell bad for a while, and lose the will to seek revenge anymore!"

Adagio gulped as Sunset, Twilight, Rarity, Rainbow Dash, Pinkie Pie, Fluttershy, Applejack, and Sonata surrounded her facing away from her. They all stuck out their butts and farted as loud as possible, except Fluttershy, who farted silently. Adagio fell on her butt and the girls walked closer and continued to hit her with a flurry of farts. They all farted loudly except Fluttershy, whose farts remained silent, and some of Rarity's farts were silent too, though the rest were as loud as Rainbow Dash's farts.

After Adagio passed out, they continued to fart on her.

...

Adagio woke up hours after they had stopped farting. She sniffed herself and recoiled. She smelled several times as bad as Aria did the other day. And she accidentally let out a loud fart, and when her farting did not subside, she realized - Sonata must have put a fart spell on her, and set it to activate as soon as she woke up!

Adagio lay in various positions, farting as loud as possible non-stop. After an hour, she stopped farting, and made her way home.

She opened Aria's door. Aria was sitting on her bed, looking miffed. She had wet her pants in the hours it took Adagio to return.

"Phew," said Aria. "You smell really bad!"

"I know," said Adagio. "I need you to give me a bath."

"Just let me change my pants first."

"No. Bath now, then you can clean up."

Aria groaned and followed Adagio into the bathroom. Adagio filled the tub with soapy water and sat down, still in her smelly outfit. Aria washed her as she had done, and Adagio told her what happened.

"I told you so," said Aria.

"I should've listened to you," said Adagio. "Pinkie has my stone now, but I won't even try to get it back. We underestimated the power of their friendship and what they could do to us. It's useless to try to get revenge on them."

Adagio farted in the tub. She blushed, and Aria scoffed in disgust and continued to scrub her.

...

The girls put the whole embarrassing fart moments behind them - except Pinkie, Sonata, and Rainbow Dash, who would have fun with it.
