Chapter Text

Basically, before we start, you gotta understand I made this image and it did a lot of brain poisoning to me:

Anyways,

Distant footsteps echoed down the hallway into Sky’s warm and spacious bedroom. Her room was plastered with posters of various webcomics, animes and her favourite fast food restaurants. On theme with this, her floor was littered with cheese-stained burger wrappers, and loose, half-drunken milkshake cups, the relics of previous pig-outs. Pushed against the wall was a queen sized bed entirely covered in plushies, pillows, and blankets, and laid back in the middle was Sky herself, dressed in a loosely-fitting skunk onesie. Her cute little belly button peeked through the tattered, stained fabric. Somehow, despite the thick fluffiness of her attire, sweat-stains accrued under her pits, petite boobs, and heavy-set butt. She cutely nodded along to the beats in her cheesy j-pop playlist, lost in her own little world. However, the sound of footsteps grew and grew down the corridor, and as the door swung open, their source revealed herself.

“Heyyyyyyyyyyyyy sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis sis guess whaaaaaaaatttt~? :3” Mira chirped at breakneck speed, little crumbs of food flecking out from her moe-fanged mouth. Her chubby frame protested against her scrappy “FART LOADING” crop-top and adorable, shart-soaked shimapan, threatening to burst at the seams. As she leant down to her sister, she giggled, watching intently as Sky’s eyeline obviously drew to her wobbly, fatty boobs, peppered with shiny beads of sweat.

“>w> w-what?” Sky sheepishly replied, somewhat already predicting exactly wha–

BPFRHBFRhbrfhbrhbrbhbhfrfhrbhfRRFRFRRRPrfprftt…

…exactly what her sister had in mind. With a sloppy, cheekwobbling fart, the room was instantaneously filled with a rotten, vegetal stench. Stomach-turningly earthy, and seeming to cling to the nostrils, the 8-second long blast raised the humidity of the room to a tropic degree, spraying buttsweat through her stained, striped panties.

Sky let out a high-pitched squeak, her eyes wide as her sister’s nauseating fart permeated the already vaguely gross air of her lil bedroom. She froze, blushing a deep pink, before her sleeve-covered hands stimmed, a cute lil reflex to Mira’s sensory assault. Her nose scrunched up as she kicked her legs, and faux-protested :3c

“E-eep! >_< T-that’s so icky, Mira… m-my room smells all veggie-ish now… u-um, I can’t even handle those yucky foods on a plate… let alone coming from your b-big… um, squishy butt~ :3c”

A sickly-sweet, smug smirk spread slowly across Mira’s pretty face, as she closed the door behind her, locking the two girls together in the stuffy, cozy room. “Ehehehe… whaaaat’s the matter, huh~? :3c Can’t handle a little chilli-egg combo~? Served with roasted onion~? :3 and a side bowl of thick, spicy curry~? Cmoooon, sis, gotta grow up your palette sometime~ :3c”, her voice clinging and sardonic.

“U-um, if your tummy makes those… t-those stinky veggie blasts, I-I’ll just stick to my burgers, please… >_<” Sky pouted, picking up a milkshake of indeterminate used-by-date, taking some sheepish sips to de-escalate her own racing heart. “M-meaniebutt… why’d you have to let it rip in my room~? >w<”

“You think you wouldn't’ve smelled it if I ripped that one from across the house?”

“...Hmpf. Touché….” Sky was still pretending to throw a tantrum, but her occasional peeks at her sister’s wide form gave away her true feelings.

“A-and plus, I wanna show my bestie how gross my butt is >:3c! My butt put in a lotta hard work,,, …cuz it loves you and stuff :3 So… s-stop being such a tsundere, dork, I know you like it >w<”

Sky stammered a little, taken aback at how adorable her sister was being… before resigning, and patting the available bedspace beside her.

“O-okay fiiiine… >w< S-since you’re here, m-maybe you can stay and hang out… i guess :3 sit down here…” She patted the empty bed space beside her. “I, um, kinda gotta secret to tell you~ :3c”

Instead of following her basic instructions, Mira excitedly jumped forwards and glomped Sky, making her bedsprings groan in agony. She buried her face into the fluffy texture of her onesie, taking deep huffs of the never-washed girlstink, giggling in pleasure. “Whaaaaat’s ur secret huh~? :3”

Sky nervously looked to the side, before whispering in a cute, gentle voice, “uhm… well >_<... my secret is that, my, um, um…” She leant in, and whispered directly into her sister’s ear.

“M-my butt wuvs you too~!!!! >w<”

BRFFRRFWWWNNNFRFPPTT~!!!!

The sound was thick, brassy, impossibly deep and bubbly, muffled by the thick fabric and her mattress, which rumbled from the pure vibrational power of her ass~ :3. Sky squeed, and stimmed as the distinct stench of processed beef and american cheese rose slowly from beneath her greasy thighs. The powerful, nauseating complexities of Mira’s fart were overpowered by the sheer potency of her unwiped bubbleguts buttsmog. It was the fart equivalent of opening a hot oven, and being hit with the wall of heat.

“Ehehehehehe… s-sorry sis,, i-i had to toot :3c”

Mira’s pupils effectively became heart-shaped as the miasma hit her lungs. She stifled a desperate moan against her sister’s tummy, letting the grease-soaked buttfumes fill her lungs. “Bbwweh,,, goddddd~ Your fat ass smells like a warm dumpster outside of a taco bell… :3c it’s soooo fucking hot~”

Sky stuck her tongue out teasingly. “It’s not my fault stuff that isn’t junk food tastes icky… and that showering overstims me… a-and i dont like the texture of toilet paper… xP… but it does have its perks :3c... ,like making my cute sister hang out in my room all the time~”

Mira nodded and “mhm”’d along, listening to every word as she slowly pitched a tent in her panties, imagining just how swampy her sister’s fat slab of jiggly, gaspacked wobblemeat was under that onesie. “Y’know… washing down that meal with a jug of spoiled milk sorta did a number on my butt~ I totes have moar farts if you want me to hang out in ur room some more~”

Sky nodded eagerly, blushing with excitement :>. Seeing this confirmation, Mira stood up, wiggling her wide butt tantalisingly, letting Sky take a closer look. She leaned in, and gasped dramatically, noticing the thick, sludgy stains, with an especially prominent one directly over her puckering buttho-

SQQQLLCCHFRHBFRHBFRHRFBBLRRT~

Maybe having her mouth agape wasn’t the smartest idea behind Mira’s unwashed skunkbutt. Oily buttsweat speckled Sky’s tongue, airborne due to the force of her sloppy, humid brap. It was like someone had poured garbage juice into a diffuser. Taking such a concentrated mix of rotten eggs and spoiled onions point-blank was overwhelming enough, but it being blasted into her throat sent her lil heart into overdrive~! She grabbed her sisters hips, and pulled her fat butt in close for a big, sloppy, sweet kiss, pulling away and leaving a bridge of (mostly) spit~ :3

Mira felt a rush of pure lust flood her system, both in a state of full-body relief after her huge, sloppy brap, and from the sudden forwardness from her otherwise reserved sister~!

“Awwww, can’t help but press ur pretty face in 2 my butt, huuuh~? Whatcha doing that for, pervert >;3~?”

“I'm… im saying i wuv your big smelly butt right back~ >w<” She looked up and gave a cute little toothy smile :3

It was like Mira had been struck by lightning. Nothing could’ve been a more calculated cuteness overdose right to her heart, making her stumble back and land on the soft pile of greasy burger wrappers.

“Ufufufufufu… gotcha sis~ x3c nobody can resist my moe charm >w<” Sky mocked, holding a sleeve up to her mouth as she gave a princesslike giggle. “U-um,, could you,, maybe c-come closer and … >w< lick ur own fartsludge off mai tongue~? :3”

She laid back again, lounging in an adorable pose. Her somewhat regal aura was neutered by a distinct GRGMbbBLll…, the sound of her tummy warring with her last milkshake sip, making her giggly again.

Mira rose, and once again laid her body weight on her sister, but this time planting her face right next to her sisters’~. She took a moment to stare into those soft, dark eyes, to feel her chest rising and falling with lustful tension, to feel her warm, panting breath against her face… before she pressed her soft, plump lips deep against Sky’s. The taste of rotten malted vanilla grew across her tongue, making her eyes flutter, and her knees weak. All of a sudden, Sky wrapped her arms around Mira’s torso, and pulled her in tight~!!!

bbbwwUUURRRRPPGghhhh…

Sky’s eggy, raunchy belch filled Mira’s mouth, clinging to the walls of her throat. The pure stench was enough to tip her already horny mind over the edge~ She couldn’t help but grind against her phat thighs, as Sky drew away from the kiss, giggling as the spitbridge stretched between them.

“Ehehehe… d-did that taste alright, sis?~ >w<”

“Gghh.. r-reallyreally gross <3 but, not like ur usual gross… >:3c did you fiiinally try a vegetable huuuh~?”

“E-eep,,, nup :3, t-those were your smelly fumes, silly~ :3c I-I just burped them back… um, s-so it’s like you, uh, kissed your own butt~ I-I just wanted to share a little~ :3c”

“Nnghhh,, that’s so hawt >w<.. I see why you can’t get enough of it then >:3”

Mira moved slowly from Sky’s cheek, to her neck, eliciting cute lil gaspy moans. She kept moving down, until she was kissing just above her breasts. Reaching up with one hand, she slowly unzipped the front of the onesie, exposing her soft, jiggly, sweaty breasts. The coagulated goonsweat between her boobs gave some resistance to spreading them, but Mira managed to pry them apart, huffing the years of layered girlstench. Sky moaned and twitched, feeling her sister’s tongue against her sensitive nipples. As the zipper travelled further down her squirming body, a powerful, earthy, sewage-leak smell mixed in with the already fetid air.

“E-eww.. :3” Sky cutely feigned disgusting, wafting the air with her sleeve. “U-um… y’know… my onesie’s, like, n-never really been aired out… sooo, ur probably smelling the gradual buildup of my farts,, over a loooong time :3”

Mira grabbed her sister’s waist and started planting rapid, passionate kisses across her midriff, even tonguekissing her sweaty navel. Sky’s moans and gasps grew sharper with each kiss, the pressure shifting the volatile burgerfarts trapped in her guts. A particularly dangerous sounding grrmMMmbbllll… made Mira flinch a little, before desperately looking up into her sister’s eyes, like a dog begging at a dinner table.

“Kinda looks like you, um, wanna give my silly lil butt a kissie :3 :3c I-I think it likes you too~” Sky purred.

She eagerly grabbed her favourite plushie and flipped over onto her tummy, pointing her butt up at Mira. Even through the fluffy pyjamas, her butt wobbled like a freshly baked castella cake. Just turning over intensified the raw stench oozing from her very presence, seeping through the onesie into the humid air.

Mira eagerly pressed her face deep into the soft, fuzzy butt, and started giving it deep, passionate kisses. Each time she pressed her face in, more lingering stench would be freed from the disturbed fibres, not washed in years. The smell of unwashed ass made her tongue hang out and her eyes roll up in orgasmic bliss. Still, she craved getting even more intimate than this~ She started to unzip the butt flap slowly, her mind racing…

W-what kind of panties does she wear??? >w< I bet they’re super pretty… or rlly cute… and I bet she hasn't changed them in years,,, and.. and…

The flap fell down, revealing…

Her huge, wide, wobbly, unwiped, unshowered, filthy fartprincess butt, totally bare.

“>_< I did mention panties when it came to things that feel just like… texture icky, riiight?... my butt’s too precious for that >:3c” she mumbled shyly, wiggling her bratty brapwagon with a nervous giggle. “N-now hurry up already owo~ I-I like, really gotta,, nghh,, f-fart~ :3c”

As Mira gingerly spread her sister’s greasy cheeks, the residual swampass strung out between them, like an extra-stretchy cheese pull of ass mucus. Mira buried her face in, aligning her lips with Sky’s puffy, soft, smelly donut~ Moaning into her sister’s butthole, she begged.

“Fuckfuckfuckfuckfuck please sis… B-Blast your sloppy, bubbly, greasy junk-food braps down my throat~ >w< 💖”

Sky giggled softly, before closing one eye in concentration, and letting rip~

sqqlLLCHBBHFRHBFHFRBRRRPFPRRFBHFRBHHbhrhHHBRFBHHHBFRFRWWWWNNNRRTTTT~

The raw force of her overwhelming shart directly into Mira’s mouth made shitfumes leak out of her nose, as she maintained an airlock with her lips. It tasted like being submerged into a septic tank underneath a mcdonalds, clinging to her tongue and the roof of her mouth. The sound was the same thick, gooey, splatter of a near-empty sauce bottle being squeezed, squelching and sludgy as Sky’s sticky ass-grease was flung onto Mira’s tongue. The full 20 uninterrupted seconds of her sister’s fetid miasma being pumped directly into her lungs were enough to make her cum handsfree, shooting thick, gooey, yellowed ropes of cocksnot all over the back of Sky’s thighs.

With a satisfying little pop~!, she unstuck her tongue from her ponut, panting heavily, and softly coughing up rancid buttfumes. Sky looked back at Mira from over her shoulder, and gave an adorable little grin :3

“H-hey sis :3 do u like… wanna cuddle for um,, the rest of the day~? :3 … I-i kinda wanna sniff more of ur farts >_< <3” she modestly offered as if her legs weren’t coated in dripping, gooey, warm cumropes~

Mira’s gaze softened, totally in love with everything about her disgusting, smelly, gooner sister. “Pfft, j-just wait for this next one… I’m toootes gonna prove my farts r grosser than urs~! >;3”

“Uuuuuuuuugh… too hot ;>_<” Sky moped, trudging behind her sister Mira, who hopped an unmanned ticket gate.

The air wobbled in the dense summer heat, with the sun blazing down upon a sprawling abandoned amusement park. She thoughtfully opened the gate from the inside, sparing her sister the effort. The pair took in their surroundings, a sprawling world of fading paint on metal structures. With a skip in her step, Mira gleefully led Sky deeper into the park. The weathered asphalt paths led the girls past old carnival games, long fallen into disrepair.

“Eugh… it’s so.. creepy in here…” Sky mumbled, double-arm hugging her emotional support plushie extra tight. For this rare occasion called “going outside”, she wore a tattered old invader zim shirt, and despite the heat, a pair of fluffy pyjama pants.

“I know, riiight~? :3 eheheh~! It’s soooo cool~” Mira chirped, flashing her moefang as she glanced back at her sister. Going outside made no difference to her attire, it was still just her crop tee and panties :3. She eagerly bounced towards a dilapidated food stand in the centre of the park, beckoning Sky over. “Cmoooon, sis~ :333 All that walking’s totes made u hungry riiight~? :3 Lets get som snacks together :3”

“>_< hmpf… f-fiiine… i guess that’s a good enough apology… :333 eheheh… u know the way 2 mai heart :3”

Mira hopped the counter, before looking at her sister with smug, taunting eyes.

“Omg haiiiiiiii pretty girl~ welcome 2… uhmm… burger queen :3 what would you like to order~? :3”

Sky gigglesnorted at her sister’s sudden portrayal, and planted her elbows on the order windowsill, finally resting in some shade.

“U-um… c-can I p-please have a super-duper g-greasy pizza slice…? >w< She giggled, softly. L-like, the gweasiest ever~ :3c” A-and soda… m-milkshake too, p-please :3c…and,, uhm…” she stuttered, a little embarrassed about this next line “U-uhm… a-are you on the menu too, Mira? >w<”?

“Pfffft,, am I on the menu… x3c I-I guess I could come with the deal, for the right tip x3…” She flashed her fang before turning around, “ur order is coming riiiiiight up~ lol :3 and cause ur suuuch a lil qt,,, i’ll give u an extra special service :3” Mira drawled as she grabbed a premade slice from the tray, under a long-unplugged heat lamp. It smelled kinda… off… but her main concern is that it was cold!!! She wouldn’t dare serve her precious sister something icky like that… luckily, she knew exactly how to warm the greasy pizza back up :3

“Pffft.. O-oh mai GOSH sis x3 that’s soooo grooooss~ >_

w<... not like she wasn’t used to eating while the stench of her sister’s butt hung in the air…

Grabbing a large cup, Mira held down the crank to the softserve machine, which sputtered out a viscous, gloopy, notably soured milkshake. She gently placed the dubious substance on the counter, alongside an entire two-litre bottle of cola she withdrew from a run-down minifridge. Finally, she grabbed the pizza, coated with globs of shimmering buttmucus, the cheese thoroughly remelted from her radiant buttwarmth :3

“Oooooooorder up :3c but first u gotta pay… >:3”

“>_< Oh gosh… whats the uhm.. cost??”

“one kiss :3”

“Hhmpf… i shouldve known theme park food would b unreasonably expensive >w<... b-but okay :3”

Leaning over with one foot in the air, the restaurant kiosk became a kissing booth, and the two sisters drew in close. Feeling each other’s tender panting, locking eye contact for just a second (which made Sky immediately blush), before finally pressing their plump lips together in a passionate display of sisterly love. Mira confidently held the kiss, whereas Sky flapped her hands in pure gay panic. She felt her face burning up, her knees buckling in, her fists balling up, and-

SSSQQLLCHBFRHBFHBRHBFRRPFPBHFHBHHFRPTT…

-her fat ass firing off a sludgy, nauseating fart, spraying accumulated sweat against her fluffy pyjama pants. The noxious, beefy fumes polluted the air surrounding their tender kiss, and as they drew away, leaving a spitbridge between them, Mira’s face was one of total perversion.

“U-uhm,, s-sorry, sis >_<” Sky sweetly apologised… “i-i um,, got kinda,,nervous >w<”..

Cuteness overload~!!! It was like an arrow through Mira’s heart, and she wanted to do nothing more than squeeze her sister over and over :3. “Hhooooly shit,, nnice one,, nukebutt~ :333,,, you fart like a horse~” she stuttered, the bulge in her panties growing to a near uncontainable state.

“H-hmpf,,, shush >w<” Sky took a deeeeeep sip of the thick, gooey milkshake, looking to the side in a feigned flusteredness, her adorable little hip wiggle giving away her true feelings about her sister’s obsession with her. After sinking half of the thickshake in one go, she set her sights on the slice next. Picking it up, she watched in awe as the greasy cheese stretched out… before stuffing her mouth with the buttstained pizza :3

“E-eep,,,,, so i-icky >_<”... she stuck her tongue out, only after swallowing the whole thing in one go, of course.

“What’s wrong huuuh? Did your appetite for rotten junk food finally bite off more than it could chew~? >:3” Mira teased, watching her sister eat with a lascivious gaze.

“N-no, that part was yummy >w<... It’s just… I can definitely tell u had coffee,, and onionz >_< bbleh… it kinda rubbed off on it… s-stinky… =w=”

“Eheheheh… i-i ate that liek, a week ago !!! >w<... my farts rlly must lingr around my butt for sooo long :3”

“You knew that already!!! >w< they linger in my room for months if i don’t open a window…..silly b-baka >_< :3”

Mira just giggled, pouring herself a milkshake from the machine. “If it’s soooooooooo gwoss tasting, just wash it down with ur soda, twerp :3” she rebutted.

Sky pouted, but realised that was probably a good idea. She unscrewed the cap, when all of a sudden… nothing happened. There was no hiss or fizz… the soda was totally flat!! =w= N-no way was she gonna do something as gross as drink a non fizzy cola… like, yuck!! xwx…

“Miiiiraaaaa…. Is there any other soda in there… mine’s flat…” she groaned.

“Awwwww~! Ohhh noooo, flat soda?? Suuuuch a tragedy… how will you ever go on~? :3c” Mira smugly chirped, a plan formulating in her head~ “Cmere, i’ll make eeeeverything right :3”

With a mischievous glint in her eye, she snatched the two-litre bottle out of Sky’s hands. Then, she plopped her fat ass right on the edge of the counter, and yanked her panties to the side with zero shame. The humid air of the abandoned park already carried a faint whiff of decay, but proximity to the eggy blasts packed inside her butt were enough to make Sky recoil a little in playful fear.

“>_< S-sis, w-what’s my soda doing nnear your b-butt…?” Sky squeaked, her cheeks flushing pink as she peeked over the top of her tightly-clutched plushie, eyes wide at the sight of her sister’s slime-glazed ponut.

“You’ll see, silly :3” Mira ominous remarked, before aligning the lip of the bottle with her unwiped ass. She slid it into her puffy butthole with a nauseating sqllch, before scrunching up her face in concentration~

BBBPFRPFRBRFBFRBHRFBHbhfrhbfrhbfrhHFRHBFRHFRFRLLCFHFRHBRHTTTT~!!!

The rotten, sloppy blast’s timbre was altered by the plastic bottle, echoing with a distinctive ring. The cola inside churned and fizzed as the space was flooded with vegetal, earthy buttfumes, bubbling like blowing air into a liquid through straw.

After the 10 second onslaught, Mira gave a toothy grin and handed the bottle to Sky, the noxious green fumes still offgassing from the freshly recarbonated drink.

Sky gulped meekly, and gave a quick “u-uhm,,, thanks sis >w< y-you’re the bestest ever~” before chugging the fart-infused mixture. She took huge, slobby gulps, downing the whole bottle in a matter of seconds.

“Soooo~ did it work, huuuh~? :3” Mira asked, excitedly. “A-and did it taste liek kissing my butt~? :3”

Sky held up a finger, before lurching forwards.

BWUUUUURRRPPPGGGHH~

A thick, throaty belch which propelled Mira’s roast onion farts directly back into her pretty face~

“U-um,, y-yes to both >w<,,, ehehehehe…,, t-thaanks again sis :3”

Mira clapped her hands with glee before hopping back over the counter, and giving her sister a tight, warm hug~ Nothing triggered her cuteness aggression like her sister and her constantly gassy butt <3

As they continued on from the snack stall, one attraction loomed over the rest, casting a shadow onto their path. Mira swallowed the last of her milkshake before pointing excitedly.

“Eeeee! Ferris wheeeeel! :333” Mira squealed, grabbing Sky’s hand and yanking her towards the massive contraption that creaked in the hot breeze. She hopped the safety chain with ease, her thighs wobbling as she dragged her sister aboard the ground-floor gondola. “C’moooon, nukebutt! bestest seats in the house! :3 isn’t this liek, sooo romantic :3c?”

“>_< W-wait, sisss… i-is it safe?? It looks all… r-rusty and stuff =w=… a-and what if it starts moving,,,???” Sky whimpered, clutching her plushie for dear life as she waddled after Mira. With a little hop, she boarded the car, her tummy already ominously grumbling from the rancid meal…

“You’re like, the silliest girl ever :3 it’ll tooootes be fiiiine…” she dismissed, before closing the door shut with a loud CH-THUNK! “It’s a ferris wheel, it’s liek, *meant* to move!”

vvHHHWWWRRRRRRRRRR...

Sputtering to life, the motor began to veeeeery gradually turn, gently making the gondola ascend. The girls tumbled onto the worn faux-leather bench seats, Mira giggling as the ground fell away beneath them. Sky nervously squeezed her plushie as the two were lifted off the ground. Sensing apprehension, Mira moved in closer, wrapping her arms around her sister.

“Awwww~ dont be scared burgerprincess >w< i’m here for you :3” she purred, feeling her sweaty body squish against Sky’s. “And anyways :3 I thiiink i know a way to make you feel more at home in here >w<,, hhmpfh,,~”

With a cute, soft grunt, Mira closed one eye in concentration, before flooding the air with spicy, rotten girlfarts :3

SQSLQLLFBHRBHFRHBCHBFBHFRHFRHFHFRHFRHFRHFRHFPPPFRPFRRFRHTHTT!!

If there was any clean air inside the cabin, there wasn’t anymore. The cramped airspace meant that her milkshake-fueled skunkgirl fumes converted the gondola into a dutch oven. It rattled the windows, the humid swampass particles sprayed out from her ass fogging the glass a nuclear green. Mira’s eyes rolled back in fartgasmic bliss, her thick greasy girlboner throbbing hard against her panties~ :3

Sky squee’d, stimming against her sister’s thighs as the disgusting dumpsterstench filled her nostrils. She snuggled up even closer to Mira, taking cute little huffs of the fetid atmosphere. Both of their butts had left deep sweatstains on the shiny seats, oozing in the sun-baked cabin.

The cabin jolted slightly as the wheel turned further, reaching a quarter of a rotation. The motion made Sky’s gut slosh audibly, and she felt a familiar pressure building in her guts. She tugged on Mira’s sleeve sheepishly, avoiding eye contact. “U-uhm,,, sis… >_<”

“Yes, qt~? :3 whuts up,,? owo”

“>w< M-my butt… i-it w-wants to say t-thank you… f-for being the bestest sister ever~ :3c”

Before Mira could even respond, Sky leant forwards, showing off her cute, years-unwiped sludgecoated buttcrack, peeking over the top of her pyjamas. The sound began slow as her fat cheeks trapped her fart, but as the pressure built, it evolved into a nauseating, beefy eruption.

ssqqllccchbbhhbhbfbhhfrhbfrHBFRBHFFBHHRRRNNNNNNNMFRFRPRTTTTTT~!!!!

:3

A combo of fryer grease and american cheese, her fart lasted a solid 15 seconds, pumping her sewersmog into the confined box :3… the potency of her unwiped butt quickly overpowered the lingering remnants of Mira’s previous outburst, making her farts inescapably toxic. Mira took deep, proud breaths, before moaning softly, which made Sky flustered and giggly >w<... “o-oh my GOD,,, >w< i luv ur butt so much sis <3<3<3”

“Ehehe,, >_<... i a-always forget how gross my, p-pizza farts are~ xwx” Sky muttered adorably, casting her eyes downwards. Her gaze met Mira’s thick, smelly girlcock, hanging over the top of her frayed panties which had become unable to contain it :3c. She immediately gasped, squealing a little,, and quickly looking away, her eyes wide >w>... “w-well, uhm,, im,, im glad you d-definitely like them >w< ,, ehe <3”

KRRR-CHUNK!!!

The ferris wheel stopped, finally at the peak of its rotation. The two sisters were surrounded by fetid buttfumes, with a beautiful, sunlit view of the entire park. “Omg lookiiiit! We’re the queens of the world :333” Mira cheered, pointing out of the grimy window at the sight.

Sky peeked out shyly, hugging her knees up to her chest. “It’s kinda pretty,, yeah >w< ,, i just like that there’s n-no one else except,, um,,, just us and our… um… f-farty butts :3c”

Mira looked at her sister lovingly, feeling a warm, romantic bliss swell up inside her. She was pretty certain she could spend every day of her life with her sister,,, even if her farts were rreallyreally gross.... :3c…

“God you’re so cute,, jfsdfhgj >w< … I love you, sis :3 <3”

She reached out, and held Sky’s chin with her hand gingerly, staring at her lips. Sky’s expression softened, even though her internal monologue was constant gay thoughts >w<.. Finally, the two drew together in a deep, long, soft kiss, surrounded by their combined stench :3. The same way their noxious buttfumes mixed together in the warm air, their spit mixed in their mouths, and their feelings for each other united :3

GGRRMmmmmMMBBLL….

A spitbridge formed as they pulled apart, Sky giggling at Mira’s tummy rumbling ominously :3

“awwww~ x3c,, I think my butt g-got kinda jealous… It wants all of ur kisses for itself :3c” Mira purred, before standing up, wiggling her hips~ Sky’s face aligned perfectly with her sister’s doublewide fartpacked butt >w<... Mira excitedly slid her panties down around her chubby thighs, before buckling her knees, hovering her naked wobblemeat dangerously close to her sister’s face :3

“>w< hurry n kiss it,,, i-i cant hold it in much longer x3… my butt is all packed with eggy, bubbly fartz :333”

Sky gulped, before spreading Mira’s wobbly fartbutt… :3 Pressing that pizza into her buttcrack left some cheesy residue glueing her swampass together, which then stretched across her heavy cheeks as they parted. Her thick, puffy butthole was coated in gooey shartsludge, making the stench already dizzying >w< Sky giggled, tucked her hair behind her ear, and leant it, making an airtight seal between her mouth and her sister’s guts <3

SSSSSSSQQLLCHBHBFHBBHFRHBRHBBHHBBBHBHBHFBHFBHFHBRRFRRPPPPPFLRFLRFFHBFBHFBHFHBRPTTT~!!!

Pure concentrated rotten-onion milkshake fart blasted out of Sky’s nostrils from the inside as the pressure built in her mouth. The mephitic fumes echoed down her throat, with a satisfying, deep rumble. Her cute lil tongue got speckled with flecks of shit as the fart continued on, gaining a wetter, sloppier tone. After her lungs were completely filled with her sister’s noxious farts, Sky broke the kiss after a solid 15 seconds, coughing a little from the raw force of her brap,, but it wasn’t like Mira was empty :3c Her huge, greasy shart continued for another 7 seconds, blasting the rest of Sky’s face with decaying, spicy septic tank gas :3 Both of Mira’s hands were on her thick, throbbing cock, stroking it as her g-spot was pounded by her own hyperfart :3

“*cough,,cough,, >_< e-ewwwww!!! U got some icky stuff on my tongue >w< bbleh,,,,” Sky kicked her legs excitedly as her capability for thought came slowly back :3c It felt so,,, perfect, swallowing her sister’s sloppy skunkmaxxer sharts >w< … it made her feel so warm and comfy inside,,, so much so that she built up the courage to say something ,,, l-lewd :3c

Mira sat back down next to Sky, to admire how fartnuked her pretty face was. This time, Sky was the one to wrap her arms around Mira, leaning in with a seductive smirk. “H-hey sis,, yknow,, ,, we still have the whole way down to go…” She cutely spoke as the wheel began to turn again, beginning their slow descent. “i-if you wanted, um,, help with, that :3c…” She gestured toward’s Mira’s leaking, stinky girlcock~ :3 “w-well,, umm, yknow… >w>” She leaned in, her soft, pretty lips parting gently as she whispered into Mira’s ear~ “i-i, like, really need to, fart… l-like,, really badly,,, i g-got such bad bubbleguts after that milkshake,,,,, s-so,,, u-uhm,, y-yeah >_< <3”

Mira looked at Sky with a desperate lust, before begging with a moan.

“Please.”

Sky just giggled, before hoisting herself onto Mira’s lap. Her fat butt slammed against her thighs, the pyjama fluff making it even softer than normal. The feeling of Sky’s wobbly fartbutt against her cock was enough to send her into a frenzy, and she reached around to grab her sister’s tummy. Sky snickered, reaching back to adjust the shaft, making sure it lined up perfectly with her butt :3

“Eheheh,, ww-woahh, you’re so handsy today, huuh~? >_<... w-wanna squeeze the farts outta mai tummy, huh? :3 go on,, sis,, d-do, um,, your best >w

pleasepleaseplease,, sis,, all i want is your huge,,, sloppy buttsmog blasts in my lap >w< ,,,” Mira panted into Sky’s back, kneading her doughy, grumbling tummy.

“Hghhgh,, h-hey,, ccalm down,, im,, o-oh,, ffffhhh,,, i-i ,, i can’t hold it!! >_< o-oh,, god,, im g-gonna-

SSSHHHHQQQLLCBHFBHFBHFHBBHFHBCHBCHBHBCHFBFHBRFHBRFHBFRFPRPRTTTT!!!!!!

The sound was like blowing air into a mudpit, blasting from her wide, stinky butt with a totally viscous, gooey, sloppy texture, echoing through the gondola. Her sweaty pyjamas were suddenly plastered with fresh, sludgy shart, forced out by a constant, bassy, beefy rumble. Mira’s hands still massaged her tummypudge, meaning she had no control over the fart - it just kept going… The vibrations of her putrid, greasy gas alone was enough to get Mira’s fat, sweaty fartboner on edge… The beefy miasma flooded Mira’s senses, a constant assault of rotten cheese and spoiled milk, until finally, something made it stop. Yet, Sky’s tummy still groaned and grumbled.

“>_< o-oh good,,, uhm,,, I t-think that pizza mightve,, g-gotten through me quick >w<... I-I think u-umm,,, my butt w-wants to , really,, show u how much it wuvs u,,,, >w>”

“Nnghh,,,:3c ppleasepleaseplease,, Sky,, hoooolly sshit,,, i need you,, p-please,, sshit on my lap >w<,,, i-i wuv u,,,”

Sky giggled cutely, holding her cute girl powers over her sister’s head~ :3c “hhh,, you're g-gross :3 i-if i do you totes owe me like, infinite kisses yknow :3c ,, ehehehe,, f-fiiiiine >w<”

She got up, and bent over, wiggling her cute butt in an awkward lil dance >w<... t-then she grabbed either side of her pyjamas and pulled down,,, revealing her already shit-coated wobblebutt~ :3

“Nnhh,, sis,, i-i want,,you to,, um,, c-cum for m,mai,, >////< ,,p-pooplogs,, owo~”

She balled up her fists and made a cute lil noise, before pushing… A thick, steamy, warm, shitlog slowly coiled out of her thick, unwashed butt :3c ,,, At the same time, Mira’s constant gooning finally sent her into fartgasmic bliss,, and she shot thick, yellowed, gooey neetgirl cumropes~!! “Ooh,,, fffuuuuck,,“ which coated Sky’s cute butt and her wide, crowning poop~ :3 ,,,, The looong pile of manure finally broke off under gravity, landing on Mira’s lap with a satisfying SSHLLCk…,, Sky took in a deep sharp breath of sexual relief, her butthole contracting after pushing.

Both girls got a reward for their hard work~ For Sky, the relief of finally letting out the last of her rancid milkshake pizza farts,,, and for Mira, Sky’s post-poop farts blasting into her face, as she still twitched and leaked :3

Sky meekly whimpered,, before pulling her pants back up, without wiping :3 “E-ehe… d-did my b-butt make you h-happy, sis? >w<”

Mira sank into the seat, as the gondola reached the ground. The doors opened and the girls both realised just how different the atmosphere in the cabin was from when they entered.

“You’ve like, so definitely earned all the kisses u could evr want >w< <3<3<3 ,,”
