Traveling back from Japan had taken over thirty hours for Nerissa and Bijou. The actual air time was a paltry sixteen hours, but then there were all the layovers, delays, and traffic gridlocks on the way out of the airport. When they finally left the city lights behind and pulled up to the cozy suburban neighborhood Nerissa called home, they were running on six hours of sleep across the last three days. They were so utterly drained of energy that they had to open the door to Nerissa's house by collapsing against it.

Aside from the rolling suitcase and overstuffed backpack, Nerissa entered her home with a towering armful of Culvers bags, each one gravid with thousands of calories. Somehow, within the foggy stupor of sleep-deprivation, Nerissa had found the strength to make a fast food detour on the last stretch of their homeward journey.

Bijou helpfully slipped past Nerissa to clear the kitchen table. When Nerissa had enough clearance to set down her haul, it sounded like she was offloading a bag of bricks. Hands on her wide hips, Nerissa regarded her purchase with a wholehearted sense of American pride.

“Thank God they were open this late,” Nerissa said. “I would have literally killed myself if I had to go to bed on an empty stomach.”

“...you're really gonna eat all of that?” Bijou asked, taking stock of the many, many, white and blue boxes stacked up like miniature shipping containers.

“Of course! God. I've been looking forward to this for weeks, you have no idea~!” Nerissa started rustling through the bags, lifting up cartons of waffle fries, double cheeseburgers, chocolate shakes, and piles of golden deep-fried cheese curds. There was enough food spread across the table to feed a family of five, but the only ones partaking would be one tiny gem girl and one extra ravenous diva. Nerissa licked her lips, eager hands wandering over every dish looking for a place to start.

Bijou giggled. “Wow, Nerissa, you should see yourself right now. You look like a starving cat being offered a can of tuna!”

“Excuse me?” Nerissa exclaimed in her trademark tone of mock offense. “Don't bully me, I'm just a hungry bitch who needs something other than seafood.”

Nerissa thought back to the culinary delights offered across the ocean. The sushi was wonderfully fresh and the ramen was divine, and there were plenty of good eats to be found at street vendors' stalls and inside every conbini...but when those small serving sizes disappeared after a few modest bites, her mind kept returning to the hearty filling sensation that only American fast food chains could deliver. And now, finally, she could sate that craving.

Nerissa grabbed one of the cheeseburgers (why not start with the classics?) and took the first of many reverent bites. The juicy flavor tickled her taste buds. Her eyes closed, lost in a dreamy sensation of grilled-goodness that had been withheld for so long. From there, the brake lines for restraint and good table manners had been cut off and thrown out. Cheese curds were shoveled down with barely enough time to chew, let alone savor the taste. Entire bags of fries were reduced to crumb-specked packets fluttering to the floor. Tall cups of soda sluiced down her throat, chased with more mouthfuls of burger. Little escaped without being dipped in cheese sauce, adding another layer of fat to her celebratory feast.

During this tempest of gluttony, Bijou watched from the sidelines with wonder. She had known of her friend's fondness for Culvers, everyone did, but this was truly impassioned! Like two lovers finally rushing into each other's arms after decades of unjust separation. Every moment that wasn't filled with scarfing and chewing was spent reaching for the next item.

Nerissa gulped down another burger and stopped to catch her breath. “Hmm? Biboo, are you not hungry?”

“Oh...no, I mean I already ate.”

“What? You mean that little bite? Girl, c'mon, I bought this for both of us!”

Unfortunately, Bijou wasn't a big eater. In fact, she was closer to a sparrow or hummingbird with how little food intake she required. Bijou made a few more token attempts to nibble at a bun, or peck at a fry, but her contributions were largely already completed.

Most people would have moved the leftovers to the fridge for breakfast the next morning, or called up some of the other Ravencrofts to finish it off, but Nerissa was too personally invested. She couldn't stand to see such warm, fresh preparations go to waste in the fridge or ferried off to other members of her family. So she continued, packing down another three burgers, another two boxes of cheese curds. The final boss of the night was a tall fudge sundae, one she had specifically requested with extra whipped creamed and a thick drizzle of hot caramel.

Bijou whistled. “You sure ya aren't going to explode after that?”

“I'm not- buuuaaAAARRRRP!” A massive belch interrupted Nerissa's reply. She quickly covered her mouth and excused herself with a voice much cuter than what had just left her lips. Now that she had a second to collect herself, Nerissa realized how incredibly full she was. Like taking a break between reckless shots of alcohol, the effects her body was going through was rapidly catching up to her. Nerissa swooned and leaned back in her chair, slowly rubbing her taut, bloated midsection that strained the tight corset of her outfit. The prudent thing would be to leave dessert for tomorrow; she'd already eaten enough to last through the next eighteen hours.

Then again...the ice cream would melt overnight. And keeping it preserved in the freezer wouldn't taste as good afterwards...

Nerissa's spoon was already diving into the semi-melted mass of vanilla ice cream. Spoonful after spoonful disappeared behind her full lips, adding a cold creamy treat to the warm mass in her stomach. She immediately felt the telltale pangs of indigestion twisting her guts, but leaving a sundae half-finished would have been even worse than throwing the whole thing out.

ggrrggg

Another bout of cramps grumbled through her tummy. Though Nerissa tried to downplay her condition as “hot girl IBS”, the truth was that, after so many pounds of greasy fast food and dairy, her gas was a chemical weapon. She thanked God that the two of them had decided on separate beds for the night, because otherwise Bijou would have been caught in the worst possible crossfire.

While Nerissa dug out the rest of the sundae, Bijou stood up from the table. A handful of fry bags shuffled under her fingers. “Uh, Nerissa, I'm gonna go to bed, okay?”

Nerissa looked up from her meal and nodded. “Oh, of course! Sleep well, my precious gem. I already told my family not to bother us up there, so stay in bed as long as you want~.”

Bijou gave her a small hug (something Nerissa audibly fawned over), then trundled up the stairs. The exhaustion was catching up with her. She tried to remember which bedroom was Nerissa's and which was the guest bedroom. Bijou swayed left, then swayed right, her brain refusing to break the navigational stalemate. “Eh...I'm pretty sure it's this one,” she mumbled under breath and chose left. Even if she was wrong, Nerissa would gently wake her up and guide her to the correct room. Or maybe they'd just cutely fall asleep together like old times.

She opened the door to a mostly dark room. From what little she could make out from the hallway's ambient light, there was a huge, nicely-made bed in the middle of the room. It looked like she could lay down, stretch out, and still have plenty of clearance length-wise to fit another Bijou.

Bijou fumbled for the light switch but couldn't find it. Sighing, she changed into her pajamas in the hallway, then wandered into the darkness, blindly stumbling around until her shin bumped against the bed frame. She slipped under the covers, so disoriented that she had managed to go in upside down. Her feet were tucked under the pillows by the headboard while her face was somewhere down towards the middle of the mattress.

She dedicated a few moments of squirming around to try to orient herself, but the urge to sleep soon overpowered her stalling. Being completely enveloped by the covers wasn't that bad, actually. As she drifted off, Bijou noticed how impeccably soft and form-fitting the bed was-- one of those expensive memory foam mattresses that would be perfect for someone with back problems.

“Oh my God...” Nerissa moaned, leaning back in her seat and drawing a few pained creaks from the chair's legs. The wreckage of her meal lay splayed out in front of her, looking like the aftermath of an all-you-can-eat buffet. Her skin was slick with sweat thanks to a mild case of the “meat sweats” after shoveling down so much food in one sitting. She closed her eyes and nervously waited for her meal to settle...which it didn't. Her stomach was an angry, bubbling mass of greasy meats and heavy dairy. Nerissa knew that in a few minutes she would be unleashing the most rancid farts in the country.

She got to her feet, leaving behind a large sweaty imprint of her fat ass on the kitchen chair, and stumbled upstairs to her room on the left. In the light of the doorway, she quickly stripped out of her outfit, tossing each piece of sweat-soaked clothing in the direction of her hamper. She threw on the single piece of clothing she wore to bed; a thin black t-shirt with Advent's logo on the right breast. The threads were horribly stretched out by her huge tits, and the hem barely covered a fifth of her unbelievably fat ass, basically just resting on her shelf of a backside. As much as she loathed wearing anything to bed, Nerissa didn't want Bijou to see her nude body if she came to see her in the morning.

Another sharp pang of gastric discomfort doubled her over. Nerissa braced against the door frame, sweat running down her face, exhaling slowly through her mouth. She wondered if she needed to blow up her toilet before turning in for the night, but, after a moment of consideration, she decided against it. From experience she knew she would just be pushing out bowl-echoing farts for the next hour and anything “productive” wouldn't happen until well into the following day. Nerissa clutched her tummy, and slowly approached her bed, feeling for its edge in the darkness. A few farts almost slipped out, but she clenched her enormous cheeks just in time to keep them locked in. She was making damn sure that every ounce of her horrible flatulence would be safely contained under those covers; the last time she freely gassed out her room, the smell lingered for over two weeks even with all the windows open.

With a sigh, Nerissa slipped under the heavy covers, turned on her side, and let herself sink into her comfy mattress. The wooden frame groaned under her weight. This was bliss. Her stomach growled as angrily as ever, but, now that she was snugly in bed, that was no longer her problem.

–

Bijou was pulled out her dreams with a start. The mattress had shifted; someone was climbing into bed with her! Bijou waited patiently for her eyes to adjust to the night. White shapes resolved in the darkness, inches from her face. Two massive pale moons of ass were resting on top of each other, each cheek bigger than her head. Thick streaks of sweat dripped down both cheeks, already creating a light gray puddle around the bed sheets where the runoff collected.

Nerissa!

An unpleasant heat wafted off Nerissa's ass and warmed Bijou's face, alongside a sour musk that made the gem squint her eyes. She considered that Nerissa had been traveling for over a day, walking thousands of steps through busy airports and marinating in her stink during that long, long flight. Never once had Nerissa gotten a chance to give her skin a chance to breathe or take a proper shower.

Stifling a cough, Bijou tried to shimmy backwards and slip out from the covers. She had obviously made a mistake in room choice but there would be an empty bed if she took a right at the hallway instead. But the covers were so heavy and Bijou was so low on energy that she could barely move.

A low gurgle emanated from further up the bed. Bijou heard Nerissa groan, and the raven's body started to shift. The gurgling pitched up, then went much lower. It didn't sound like hunger pangs.

“U-um, Nerissa?” Bijou ventured meekly, trying not to startle Nerissa too much. “I went into the wrong bed. Could you-”

Nerissa grunted and pushed out a loud, wet, cover-fumigating fart right into Bijou's unsuspecting face. The low tones slapped through Nerissa's heavy cheeks and rippled her ass meat like a waterbed, splattering the immediate area in butt sweat. The small pocket of air under the covers was instantly filled with the warm, hellish stink of expired cheese and rancid meat. It was so rank, so thick, that Bijou could feel it sticking to her face! Bijou gagged hard and tried to turn her face, but her body wasn't listening.

“Mmm, fuck yeah...” Nerissa moaned dreamily from up by the headboards. She'd been holding that one in for dozens of hours, and it felt so damn good to finally unload. There was a brief moment of relief as the pressure in her gurgling gut relented, but it was filled just as quickly. Nerissa shimmied her hips under the covers, biting her bottom lip.

Another meaty ripper trumpeted out from Nerissa's caked-up backside, adding a fresh layer of disgusting crack sweat to the swirling methane sauna eating away at Bijou's precious little air supply. The weight of Nerissa's covers struggled valiantly against the force of her release, rippling like a flag caught out in heavy crosswinds. It smelled just as nose-burningly awful as the first one, and forced another couple of dry, pained coughs from Bijou's throat.

“Nerissa...” Bijou croaked weakly, forced to breathe in more fumes for her effort. “P-please stop...”

But Bijou's pleas went nowhere. Nerissa was deep within the trappings of her dream, on a cafe date with her beloved Marine. The two of them were sharing drinks at a restaurant on the beach's edge. Tall tropical beverages as blue as the water at their feet. Nerissa heard something far in the distance that turned her head. Some kind of small animal squeaking at her. It sounded like it was in pain.

“Something wrong?” Marine asked, tugging at her skimpy bikini top and letting her fat udders bounce.

“No, nothing,“ Nerissa replied. “Must be the heat.”

Satisfied, Nerissa relaxed into her pillow and let out a long, hot, sputtering barrage of gas. It was a weaker release that barely fluttered the covers, but made up for it in concentrated stench. Heat washed over Nerissa's lower body, sweat flashing onto her bare, thick thighs while Bijou continued to suffer.

The air under the covers grew terribly foul and humid. The blankets and bed sheets were already so soaked in Nerissa's gaseous waste that they clung to Bijou's skin like damp cellophane. More tones from Nerissa's fast food binge hit Bijou's nose as the air thickened in her scent: mayo, rotten veggies, sickly sweet vanilla, and spoiled dairy. Bijou tried to push herself back, anything to get a few centimeters away from Nerissa's ass.

Bijou finally found the means to turn her head towards the ceiling. She was still trapped in the devilish diva's putrid dutch oven, but at least she wasn't staring directly into Nerissa's fart-spewing crack. Bijou took a few short breaths through her mouth and cherished her small victory. She could feel her exhausted body waking up; in a few short moments, she'd have the strength to slip outside.

Meanwhile, Nerissa gripped and readjusted the covers, allowing the smallest hint of what had been trapped under the covers to seep out. Nerissa grimaced, shocked into a half-awake state from the vile smell smacking her nostrils. Fortunately, she had a solution; she just needed a little change in position. Starting from her shoulders, Nerissa slowly started rolling onto her back.

In the warm darkness, Bijou heard her bed mate shifting. A second later, she felt Nerissa's buttcheek brush her ear as the rest of Nerissa's ass loomed overhead. Eyes wide open, unable to change her fate, Bijou remembered a fun fact about Nerissa that everyone had always teased her about: Nerissa never wore panties.

“W-wait!” Bijou screamed, suddenly finding her voice. “Nerissa don't- MMMFFH!?”

The rest of Bijou's plea was summarily swallowed by Nerissa's naked, sweaty, dump truck ass steamrolling over her face. The foamy mattress gladly compressed and molded around Bijou's body as she was smothered and driven downwards under Nerissa's heavy buttocks. The rest of Nerissa's tall, voluptuous body easily eclipsed Bijou's frame, leaving only a spray of silver-violet hair to let anyone know Bijou was sharing the bed.

In only seconds, Bijou's situation had gone from bad to unbearable. Her body was immobilized, now acting as Nerissa's second mattress. Her poor face was buried under fat, musky, unwashed girlfailure ass, wedged so deeply between those wobbling bare cheeks that she could no longer hear Nerissa's mumbling sleep talk. Bijou tried another call for help and was instantly muzzled by Nerissa's greasy shithole meeting her lips. With no panties, or even a flimsy thong as mercy, Bijou was lips-to-asshole with the greatest casualty of Nerissa's sloppy hygiene. Bijou squirmed and kicked, but the small girl's thrashing barely jostled the mattress, let alone the amazon sleeping peacefully atop.

“Mmm...okay, we'll check out the fountain later...” Nerissa mumbled, wrapped up in a quaint dream of touring a European city with Kiara. The flowers were in full bloom and there were countless markets to frolic through while holding her girlfriend's hand. There was just the little problem in her tummy...

Nerissa frowned and gripped the bed sheets. From the depths of her crack spewed a horrendous cheek-slapper of a fart, slamming against Bijou's features point-blank like a howitzer. Four uninterrupted seconds of extra rancid Midwestern braps battered Bijou's nose and mouth like a speedbag, the smell magnified to such extremes that Bijou could taste it dripping down the back of her throat. The heat dried out her tongue, then was refreshed by the wetness flecking off Nerissa's muggy crack. Pained tears sprung to Bijou's eyes as her body flailed uselessly under Nerissa's oblivious, spluttering assault. Even one second of choking down those fumes was enough sensory trauma to last a lifetime.

Her tormentor wasn't done. As soon as one fart squeaked to an extra wet finish that bathed Bijou's tongue in ass sweat, another roared out. The sound trapped between Nerissa's cheeks and Bijou's face made a low, bassy rumble, vibrating through the entire mattress and lightly shaking the bedposts. Anyone in the room would have clearly heard Nerissa's fart snarling into her mattress, so, for Bijou, it was a thunderous din that slapped her eardrums as well as her nose.

Another lewd, unashamed grunt of satisfaction rang out from above as Nerissa felt her stomach settle back down. “Okay, okay, I'm coming,” Nerissa said to her dream companion. ”Yeah, I'm better now...just had to empty the tank, ehe...”

While Nerissa pursued the next act of her unconscious fantasies, Bijou was left to stew deep within the musky, dripping crack of Nerissa's big fat American ass. For the next six hours, ninety-nine percent of Nerissa's vile sleep farts went straight up Bijou's nose or mouth, depending on where Nerissa had shifted herself. Whatever gas slipped through the Bijou Filter ended up under the covers, which were brimming with the demon's earlier gassing.

Time limped by with agonizing slowness. Nerissa's farts had receded a little in power, but there was never a thirty minute block that passed without a putrid stream bubbling against Bijou's face like a methane leak. Her skin was soaked in Nerissa's ass sweat, puddles of the stuff had started gathering around the back of her head as it poured down over the sides of her face. Nerissa's body weight had rendered most of Bijou numb, and she stopped trying to move her arms or legs. Even filling her lungs was a momentous task with all of Nerissa pinning her flat chest, so she constantly felt short of breath.

Whenever Bijou felt the merciful grayness of unconsciousness close in, another low-pitched fart splashed against her face and threw her senses into high alert. She remained caught in a twilight of the waking world and dreams, subsisting nearly exclusively off of Nerissa's sloppy, aggravated dairy farts. The only thing keeping her sane was the knowledge that Nerissa couldn't stay here forever.

Bijou's internal clock assured her that morning had come, and that the longest night of her life was at an end. Indeed, the sun had already risen and knocked at the blinds with its warm orange glow, but as Nerissa had cheerfully pointed out back in the kitchen, they were free to sleep as long as they wanted. And with all the sleep debt incurred by international travel, Nerissa was settled in for the long run.

Nerissa snuggled into her pillow with a look of contentment. A new scene took form in her dreams. She was on a picnic with the other Advent girls among a field of violet roses. Everyone had brought some sort of dish and was proudly showing it off. Nerissa wanted to ask how Mococo became such a capable chef, but paused.

There was a stubborn itch between her cheeks.

Nerissa sighed. It was a common occurrence with an ass as big as hers and one of the many reasons she didn't like wearing underwear. It would be uncouth to dig in there among company, so perhaps she could just wiggle around...

Nerissa started thrusting back and forth with her hips, sawing Bijou's face between her fat cheeks. Bijou whimpered as her nose ground across Nerissa's pussy lips, her slick taint, then smashed against Nerissa's tacky asshole. A full tour of getting her face flossed through Nerissa's slimy, sweaty swamp ass like a gym towel. The bed creaked from the force. Through mouthfuls of crack sweat, Bijou found a window to cry out her Nerissa's name, pleading that she would be awake enough to register that something was wrong.

The creaking stopped. Up by the headboard, Nerissa tilted her head. “Hmm? Biboo, is that you?”

Bijou felt a burst of elation. Somehow she had pierced her dreamscape! “Yes! Nerissa, I'm down here!” she tried to call, but it came out as a series of muffled whimpers.

“Oh, hey. Yeah, I guess you're right,” Nerissa said to the Bijou in her dream. The two of them had met up by the food stalls of a nighttime carnival. Nerissa confessed she had been feeling rather bloated, and dream Bijou suggested finding a secluded place to “relieve” herself. Nerissa slipped out from the strings of yellow lights, past the dark crowds of costumed guests, and ducked into one of the restrooms. Her stomach had never been in this much distress. She slammed her heavy ass down on the toilet seat, ready to destroy the stall.

Back in the real world, Nerissa's sweaty asshole winked and completely smothered Bijou's nose. The smell was ungodly, instantly sending Bijou into a lightheaded daze. Bijou braced herself the best she could, though it felt like holding onto a sapling to endure a tsunami. She could hear the gurgling churns echoing from Nerissa's guts. Nerissa flexed the abs hidden behind layers of plush tummy fat and grit her teeth.

An onslaught of juicy, pent-up Midwestern PAWG farts from the depths of Nerissa's colon blasted up Bijou's nose, fumigating her poor sinuses with braps so disgustingly wet that small bubbles formed around the seal of her nostrils. Pure shitstink rocketed down the gem's nasal passage, filling her sinuses then rushing down her throat. Bijou choked and gasped like a dying fish. The smell was unbelievable when snorted straight from Nerissa's asshole. The amount of gas overflowed Bijou's divot in the mattress, spilling out from under Nerissa's wobbling ass and further heating the area under the covers.

It droned on and on, until Bijou was convinced she would run out of air to breath. When it petered out, she was left not just crying, but sobbing into Nerissa's ass. Her tears blended perfectly with the leagues of ass sweat and fart juice slathering her face. A few final farts burned her nostrils, but Nerissa had finally emptied a significant amount of her stock. Now all that was left for Bijou was to soak in it.

For the next four hours, Bijou's only job was to filter the stale farts that had been pushed out all evening, of which there seemed to be an endless supply. She was huffing farts from when Nerissa first laid down, pulling them into her airways and breathing deep to suffer their taste thousands of times before her service was done.

At four in the afternoon, Nerissa finally opened her eyes. Her body felt simultaneously wiped out and extremely refreshed. While she didn't know the exact time, something told her she'd been out for a while and that she should get moving. She wiggled her hips, noting the surprisingly comfy bedding she rested on all night. Did she add another comforter before lying down?

Nerissa sat up with some effort, huge braless tits swaying on her chest, still tragically oblivious to the pained groans of the girl whose face she was now resting almost all of her weight on. Hints of the farts Nerissa had been unloading all night rushed out to fill the air now that the covers had been disturbed. Nerissa audibly cringed while waving the air in front of her face.

“Oh my God!” She ducked into the crook of her elbow. “Jesus, those are so bad! What the hell did I eat last night?” She reflected on the feast from earlier and had to admit that this was par for the course. Though her bed did a damn good job of absorbing most of it! Sure, she may have burned through another pristine bed sheet and the mattress would need a deep clean, but at least-

Her irritable stomach gave one last lurch. “Seriously? Alright, whatever...”

Nerissa closed her eyes and grasped her rumbling tummy, for the first time pushing with all she had. A six second god-awful ripper rumbled from her cheeks and punished the mattress under her big fat sweaty ass. God, it sounds so wet, Nerissa noted with extreme embarrassment. She bounced her ass and kept pushing, making sure the “mattress” absorbed all of the stink. She managed to stop half a second away from messing herself.

Nerissa swung her legs over the side of the bedside (unintentionally mashing her sweaty taint and fart-soaked asshole into Bijou's face one final time), then hopped up to sprint to the bathroom, massive pale ass cheeks wobbling away on each step. If the stench of those pre-dump farts were any indicator, her plumbing was likely going to need some work again after she was done.

Bijou lay within an outline of shiny gray sweat that had soaked into the bed sheets. The stains were extra dark and slimy around her head, where Nerissa's fat ass had been baking her with farts for the last sixteen hours. Her small chest rose and fell like an injured bird, slow to adapt to a world without being force-fed Nerissa's gas. When the feeling came back to her limbs, she rolled off to the ground and nearly puked on the floor.

In the future, whenever some one in chat would ask what it was like sharing a bed with Nerissa, Bijou always needed a few moments to collect herself before responding.
