"What's up with the sky today?" Rainbow Dash stared quizzically upwards.

"Are the clouds.. Usually green?" Fluttershy added; one by one her friends gathered and stared up to the sky.

"What's goin' on?" Applejack looked to Twilight, expecting an answer.

"I'm... Not sure..." She thought for a second, and it hit her.

"I thought you and Discord had made up, Fluttershy." Twilight sounded concerned.

"I... I thought we had too... I haven't seen him in a while."

"This has discord written all over it!" Applejack cried determinedly.

At that moment, with a flash, the draconequus appeared before the group.

"What are you doing this time, Discord!?" Twilight demanded.

"You ought to know." He looked at Fluttershy.

"Me? No! Why?"

"Last month was the grand galloping gala, and once again you did not invite me."

"Oh... Oh, I'm sorry, Discord.."

"You will be sorry. I suppose I'm just not important enough to be seen with any of you. I'm just an embarrassment to be around, right? Well, I'll show you all that you're not so pish posh important yourselves!"

Discord snapped his fingers and disappeared.

"Wh-what did he do? Did he mess up my mane??" Rarity panicked.

"I don't... see anything wrong. Ponyville looks normal."

"The clouds are back to normal, too." Rainbow Dash commented

The rest of the day was spent full of paranoia as the ponies all tried to work out what was wrong, but they simply couldn't.

Night fell and the group disbanded to head off to bed, still unsure about what Discord had set wrong.

Twilight rolled over as her alarm clock went off, moaning into her pillow.

"Spike... Can you turn that off?"

There was silence.

"Tw-Twilight... What... What's wrong with you?"

She opened her eyes to see Spike looking on in horror.

"What?" Twilight did feel heavier than usual.

She looked down to notice her body has swollen up to about twice its usual size, her belly inflated and plump with a huge extra layer of unwashed, sweating fat.

"Wh-what??!"

She felt a strong, sharp pain in her stomach. There was clearly a lot of gas inside her and she had to get it out.

Almost without trying Twilight let out a loud, abrasive belch. -uuuuuurp-

"E-excuse me..." She said, although she didn't feel like she really cared.

"Twilight! You smell awful, what's wrong with you!?"

"I don't know Spike! I'm.. I'm massive!"

Her stomach growled uneasily. "Ooh.. And I've got seriously bad gas.."

"That's gross, Twilight! Don't come near me!" Spike held his nose as he headed to the door.

"What's the matter with me!?" Twilight asked herself, a silent fart leaking between her thighs as she sighed.

She decided to check on her friends; perhaps one of them could shine some light on the problem.

As she left her house she found her five friends sat around, groaning and moaning; they were all just as bloated as she was. Each of them had also accumulated a large amount of fat, each one resembling large snowmen more than ponies.

"Twilight... Urgh... What's happened to us?!" Rainbow Dash groaned, laboured by her heavy, bloated belly.

"I refuse to even look!" Rarity kept her eyes firmly closed.

"I don't.. Know! I..." Twilight let another flavourful belch roll up out of her mouth.

Before anypony else could speak, in a flash Discord appeared around them, laughing loudly.

"Oh, brother! You should see the look on your faces, it really is priceless!"

"What did you do, discord?" Twilight inquired, trying to hold in a mammoth fart.

"Well, I simply amplified the contents of your gastrointestinal chambers, making you all a little gassy."

"A little?!" Applejack snapped.

"Oh, please, it's only a little gas. It'll pass... And something tells me that you ponies won't find it as disastrous as you think..."

The first to break wind was Rainbow Dash, a sudden thundering fart booming against the ground. She shivered.

Discord cackled and held his nose. "I see it's already working... But don't worry, girls, there's an easy solution."

"What?"

"Just get rid of all the gas." He disappeared.

"Ladies don't do such crude things." Rarity commented bluntly.

"Oh, come on, girls.. It's just a little gas!" Pinkie Pie giggled, her tail shooting up and several popping farty blasts cracking from her fat butt.

Twilight still felt.. Strange; as if something was not normal. Her repulsion towards the current situation seemed to be lowering by the second.

"Girls.. Are you all starting to feel.. Okay with this?" The others looked at her.

"Now you mention it." Applejack responded, "what's the big deal? It's jus' a little wind, right?"

"No! No! How could you excuse something so vulgar! So uncouth.. So... Toasty and warm and wet~" Rarity wasn't sure what she'd just said.

Twilight began to panic.

Rainbow Dash laid back on the ground, holding one leg up in the air and releasing a tremendously loud fart, making Fluttershy jump and expel a short squeaker herself.

"How 'bout a fart contest, girls?" Rainbow Dash smirked.

A few moments ago Twilight would have questioned the idea, but she didn't seem to mind -- in fact, she seemed to warm towards it very much.

"Oh, and I guess you think you can win, huh?" Applejack jeered at Rainbow.

"Of course I can!"

"I guess it wouldn't hurt to let a little gas out." Fluttershy added quietly.

Pinkie just sat burping grossly into her hoof and inhaling the result.

"Not as if you two ruffians would know how to produce flatulence correctly, anyway." Rarity added.

"So it's settled!" Twilight cried.

"Each pony gets to show off their gas -- we judge them, and the winner gets to use the others as... As fart cushions! One by one!"

"I like the way you think, Twilight." Applejack smiled. "Who goes first.

"The order will be... Rainbow Dash, Rarity, Fluttershy, Pinkie Pie, Applejack, and me."

"Alright!" Rainbow cheered.

Every pony gathered around the bloated cyan Pegasus as she rolled her body over awkwardly and lifted her tail, her quivering pucker exposed.

The girls moved in as close as they all could, ready to take a sniff of what their friend had to offer.

Rainbow grunted to herself, before the floodgate opened and a loud, abrasive, raspy fart pumped out of her like a chimney. The hot, foul-smelling breeze blew over her friend's faces. The smell of her farts was not unlike rotten eggs, dashed in with a slither of burning rubber and mouldy cheese.

"Sniff it up!" She commanded -- it would have been hard not to.

Apart from a slight groan from Rarity, the gas did not evoke any particularly strong reactions from the group. They took sniffs of the venting gas; it was warm and sickly, but not unbearably so.

"Surprised you guys haven't -- Urgh -- thrown up yet!" Rainbow boasted.

"Ooh.. It smells good.." Twilight moaned, leaning right in to take a whiff right from the hole itself.

"C-come on, guys! You're not supposed to be enjoying it!" Rainbow Dash forced out about twelve blasts of gas, her frustration grew as she still received no reaction.

"Well you guys are just holding the disgust in.. I bet."

Okay.. It's your go, Rarity.

She nodded. "Rainbow Dash, you expel gas with the same manner you do anything with: forcefully, carelessly, and underwhelmingly!"

"Oh, shut up, Rarity. Not like you can do better."

"If you are so confident, Rainbow Dash, perhaps you'd like front seat." She smirked.

Rainbow Dash shrugged and pushed her way past the other ponies. Rarity laid forward with her rump held up in the air; she shook it a couple of times to further taunt Rainbow.

"Now, let me educate you girls in the correct way to.. 'Fart', as you call it."

"Correct way to fart? Rarity, ya just let rip as loud as you can." AJ commented.

"Not true. Let me show you girls."

Rarity performed a few breathing exercises; the other five ponies were waiting anxiously around her rump, with Rainbow in the front.

Suddenly, a solid squeaker emitted from Rarity's puffhole.

"A-ah. Now, you must sustain a p-perfect tone."

The fart did not waver in pitch or intensity, squealing out of Rarity's plothole confidently.

The group were beyond surprised that such a noise could be produced by such a proper pony.

Rainbow Dash coughed into her hoof; choking down the strong stench of boiled cabbage and rotting meat.

Of course, by this point, people have begun to take notice of what we were all doing. We could hear the disgruntled chattering of ponies around town who began to trot away, holding their muzzles to shield them from the odour.

Rarity's fart, to everypony's surprise, was still going. It had been about half a minute but its strength had not diminished at all.

"You must not release your gas sporadically. It must release in -urg- one steady stream. Now, observe as I manipulate the pitch."

She opened her legs wider and the pitch seemed to lower a semitone or two, and then as she compressed her buttocks the pitch rose.

"That's jus' strange." Applejack remarked lightheartedly.

"Hush, hush, we don't all share your boisterous farting habits, Applejack." She managed to reply whilst still letting loose.

She leant forward, grunting and gritting her teeth as her fart slowly tapered off into a higher pitched whine, finally coming to an end at a staggering one minute and ten seconds.

"And that, girls, is how it's done! Whew!"

"Well, it smelled worse than Rainbow Dash's." Fluttershy giggled.

"Wh-! That.. Wasn't so bad!" In actual fact Rainbow's nose was a little numb.

"Fluttershy.. You're next." Twilight smiled.

Her initial reaction was to stammer nervously, but that was the old Fluttershy.

When no pony else could see, the yellow Pegasus would be as appallingly slovenly and slobbish as possible, and she felt that side of her coming out slowly.

"If you girls can take it." She giggled.

"Well, well, this is the real you, huh, Flutters?"

Applejack chuckled incredulously.

"You bet your sweet apple cheeks... Now, all get up close to these sweet cheeks."

Fluttershy felt a wave of dominance flow through her -- although this curse gave her the worst bellyache she'd ever had, she was loving this newfound confidence and lack of worry.

She felt as her friends all shuffled together and pushed their collective snouts up to her pink tail, which lifted above her rotund buttocks, both of which were about the size of watermelons.

"Get a sniff of this!" She grunted, before she ripped a loud, crudely squealing fart with enough force to make her asscheeks tremble.

The wall of stink hit the mane six all at once, and at once they all reacted by coughing and shielding their nostrils, apart from Pinkie, who just took a deep sniff.

Without exaggeration, Fluttershy's farts smelt of death; raw and sharp and haunting. It was easily the worst thing any of the five ponies had ever inhaled, and beat Rarity and Rainbow Dash's attempts by miles.

The thick, everlasting fumes just rolled out of the pony like a constant storm, the acrid gas caused the group's eyes to immediately water and go red.

The giant toxic cloud surrounded them, and after it had been thundering from the shy mare's ass for a solid minute, Rarity, Twilight and Rainbow Dash just couldn't stand it anymore.

"That's not right." Rainbow Dash croaked weakly, using her wings to push the smell away from her as best she could.

Rarity ran to the nearest bush and began to violently throw up; she gagged and coughed and even the memory of the smell was bad enough to make her throw up again.

Applejack was close to giving up; her stomach turned and uneasily groaned and she felt bile try and rise up her gullet, only to swallow it down again and shudder. She couldn't back down and appear weak; she had to brace the storm.

Fluttershy had a lot of gas bundled up inside her, and she intended to let out the biggest amount she could.

It surpassed the length of Rarity's fart completely, the yellow Pegasus gasped and lifted one leg off the ground.

It roared on, and the persistent Pinkie Pie didn't seem bothered by it at all, despite the fact her hair was wilted and her nose was running.

"Oh, b-b-boy, Fluttershy! I never knew you had it in you!"

Fluttershy, still letting out her gas and panting breathlessly, decided to plant her fat, exuding rump right onto Pinkie's stupid little head.

"D-don't interrupt me!!" She cried, burying the Pink pony's face in the huge mound of fat that was her ass, it became muffled as the full, concentrated stream of it was administered directly against Pinkie's face.

The feeling of gassing Pinkie with such vile gas gave her immeasurable amounts of pleasure, and Fluttershy began to hoof her vagina, moaning softly to herself as she did so.

After only a few seconds, she came down her arm with a shriek.

Eventually, it came to an end, and the other members of the group came out of hiding.

"F-Fluttershy.." Twilight could barely talk.

"I think that was most of it!" The Pegasus replied cheerily, returning half the way back to her usual self.

"P-Pinkie!" She stood up, letting out an accidental fart in the process, to find her pink friend passed out and with a small rivulet of blood dripping from her nostril.

"Was that really me?"

"That was plain foul." Applejack commented as she wafted the air with her hat.

"I like it!"

"Oh.. No.. I didn't mean to hurt her.. Is she ok?"

"She'll live." Rainbow Dash commented.

"It's.. Pinkie's turn next.. Maybe somepony should wake her up?"

"Heh, I got one way." Rainbow Dash snickered.

She squatted over Pinkie Pie, looking upwards as she relaxed, and...

A small stream of glistening piss appeared between the fat folds around Dash's pussy.

It trickled down into Pinkie's mouth, and slowly filled it up until she was gurgling on the salty golden drink.

She suddenly shook, and sat up with a cry, only planting her face into Rainbow Dash's plump behind.

"Pinkie! Ow!" The cyan Pegasus got off her.

"Wh-what happened? My head's kinda woozy.."

"I... I'm sorry, I farted you into submission." Fluttershy meekly said.

"Hehe! That'll explain why my dream was so stinky!"

"It's your turn." Twilight reminded her.

"Yay! I can't hold it in any longer! Gather round, everypony! You're about to witness something unbelievable!"

As they had with the other members of the group, the mane six gathered around Pinkie's butt.

Her plot cheeks were a little plumper and more inflated than her friends.

Without a word of warning the Pink earth pony's buttocks began to jiggle against a wet, bassy fart. It only lasted about six seconds, but it was followed by several more.

"W-wait.."

Rainbow Dash grabbed a hoofful of Pinkie's fat ass, and spread her cheek.

They watched her pucker as it twitched and began to let out a low, juicy rumbler.

It smelt like spoilt dairy wiped up with a damp cloth; far more repulsive than anything you'd expect from a pony who eats nothing but candy.

Although slightly tamer in comparison to Fluttershy's monster of a fart, Pinkie's offered just as rancid a smell, Rarity found herself having to turn away just to avoid throwing up yet again.

"I-It's so wet!" Pinkie moaned, lying forwards onto her massively fat belly and putting all her weight on it. The intensity and power of the gaseous release became much stronger, her fart became incredibly loud and deep.

Every few seconds, little wet specks of gross juice would be sprayed onto the group's faces. Pinkie's farts were so wet that they took liquid form every now and then.

Her fart was only about fifty seconds, but given just how powerful and violent it was it made sense.

"That felt. -uuuurp- so -urrrrph- good~~"

She fell forwards, rubbing her own clit with her legs splayed in the air.

"Oh my.." Rarity wasn't sure what to say.

"Heh, mind if I do somethin' a little different for my turn, Twily?" Applejack inquired.

"Not at all. I think our noses could use a break, anyway."

Applejack squatted over Pinkie, the two fat bellies of the ponies squashed together, Applejack stuck her butt into Pinkie's face.

"Sniff up, partner."

Her ass erupted with a loud, disgusting fart -- nearly as wet as Pinkie's.

The pink pony continued to rub her stinking vag, her legs shivering as she endured the pleasure of Applejack's rancid fart in her face.

"Oh man, your gas is.. Is so nasty, Applejack."

"You don't need to tell me so, Pinkie, I'm proud of jus' how nasty it is."

She forced Pinkie's face between her two buttocks, giving her as much stink as possible.

"Ooh.. Ohh... Ohh.." Pinkie felt close to climax.

"I'm gonna..."

Just before she could cum, Applejack smirked and fat logs of raw manure began to squeeze out from her hole and spread over Pinkie's face.

"Ahh~! Hope ya don't mind me droppin' a few apples.."

Pinkie came hard at the shit on her face. Applejack let out a final fart to bubble up the feces.

"I... I've never seen anything quite like that." Rarity remarked. She was shocked, but at the same time she was so turned on.

Pinkie continued to guzzle the shit on her face as Applejack got off.

"Well, that's my load lifted." She laughed.

"Sorry bout a bit of mud at the end there.."

"That's so.. Hot." Rainbow couldn't help but start hoofing herself, ejactulating almost straight away.

"I believe you're last, Twilight." Rarity turned to the pudgy purple alicorn.

"Oh yeah!"

She grinned. She'd been holding it in for ages now, and she could tell hers was going to be a bad one.

"Get in position, girls." Twilight raised her tushie and wiggled it around a little.

They all trotted over to lean into her ass, Pinkie's face still caked in shit.

Twilight first let out a behemoth belch, gasping and spreading her cheeks apart.

Suddenly a fierce fart ripped through her asshole, so loud it made the other girls jump.

Twilight's fart sounded like a muffled duck quack, she thought to herself.

Of course she was used to farting around spike a lot at home, but she'd always avoided letting rip around other ponies. Her total lack of manners and hygiene really got the purple pony going.

"Sniff it.. All in!" She commanded to her friends, who were having a tough time taking rational sniffs of the gassy tsunami completely flooding their senses.

Twilight put her head to the floor and stuck out her ass even more, feeling the hot, rushing wind escape her butthole and cloud the ponies behind her.

On and on it rumbled, as Twilight let out soft belches every few seconds.

"O-ooh~ I feel like I'm tearing in half!" She exclaimed.

Before she could realise she had opened the floodgates too far, her stomach bubbled and her plot began to spray half-liquid shit over her friends. The chunks of feces covered their faces, slowly dripping onto the ground.

A loud, thundering airy fart sprayed the shit everywhere; at this stage the smell was so putrid Rarity couldn't even run to a bush before throwing up.

Her stream of horrible, stomach-churning waste alternated from wet gas to wetter solid waste.

"Stop!" Fluttershy tried to shout, only getting a dose of shit down her throat.

Phhhrrbt brrrbt brrrupt brraaapt braaaaaapt

In the heat of passion Twilight rocked herself back, forcing her huge body on top of her friends, trapping them underneath.

The torrent of shit and gas abused them, they all gagged as their faces were forced right against the source.

"So juicy.." Twilight moaned to herself, continuing to blast farts on her friends as her waste became rawer, spicier, and progressively less processed.

She rubber herself at the cries of pain beneath her, showing no mercy and she doused the ponies in the entirety of her stomach contents.

"Celestia.. O-ooh.."

She came, and at the same time her gas crescendoed in a fountain of spray.

It died down almost immediately, a huge pool of shit around Twilight with a radius of at least five meters.

"W-wow... I've never had so much gas in my life.."

"Ok! You win! Just... Get off!" Rarity screamed.

"That's just... Just nasty, Twilight." Applejack said bluntly.

Fluttershy and Rainbow were out cold.

Her friend's normal personalities appeared to have reverted to normal, but not Twilight's. She still had zero regard for them, and if she had any more gas at that moment, she would not hesitate to let rip.

Suddenly, discord appeared with a clothes peg on his nose.

"Phew! You girls really did a number here. It smells like a rotting carcass!"

Twilight only then realised that their little contest had left the entirety of ponyville deserted.

"Well, Twilight, you won fair and square, I think it's safe to say. You do remember the prize, don't you?"

"No..!" Applejack protested.

"That's right! You get each one of these ponies all to yourself.. One at a time.. Isn't that marvellous!?"

Twilight smirked. "Absolutely."

"What in Equestria's gotten into you, Twi!? Get off!"

"No, I don't think so, Applejack."

"Oh, what a shame, it seems Twilight here has rather taken a liking to this new personality of hers. I feel sorry for you all, truly I do, but of course a deal is a deal, and I have to let Twilight carry out her prize."

Twilight smiled evilly. "This is gonna be fun.."
