Jacub was quietly sitting at his desk, enjoying peace and quiet as he read a book. It was a fictional story about magic, dragons, and adventurers and the fantasy of it had him gripped. Today was the first day his two younger brothers, Jake and Jowy, had started daycare and was also one of the only days where he was actually able to relax. The two younger bear cubs were twins, four years old, and had grey and teal fur. Jacub looked identical to them, but was naturally far older, at eighteen years old. He still lived with his parents obviously, and was often stuck looking after the two mischievous twins. Despite how annoying he found them at times, they were his brothers, and so he couldn’t bring himself to hate them, or even yell at them. So when the pair suddenly barged into his room, pulling him away from his book, he simply scowled towards them. 

“Welcome home. Yeah, just come in, you don’t need to knock or anything..” he grumbled, rolling his eyes. 
“Daycare was super-duper fun bro! We got to play with lots n’ lots of toys!” Jake excitedly squeaked as he walked in front of his twin brother. Jowy wasn’t far behind, shooting a wide grin at his older brother from behind the other bear cub. 
“Uh huh! But we missed you lots!” he added, stretching. Clearly, the two had just been dropped off home from daycare whilst their parents went to go do the shopping, cutting Jacub’s day off short. He put his book down with a huff and turned to address his brothers, but the sight of them gave him quite a shock! The two bear cubs were wearing nothing but underwear, and most notably both of them had incredibly bloated, gurgling stomachs. 

Both things had Jacub’s ears drooping. Firstly, he hadn’t gotten used to seeing the two tykes out of diapers yet, as they’d only just finished potty training, and seeing their tummies so full spelled very bad news. Both the twins were infamously gassy - they were lactose intolerant, allergic to most foods, and were generally just walking fart-machines. Jacub opened his mouth to ask, but Jake beat him to it.
“We had tacos today!”
“Uh huh. They were yummy! Better than the boring food mommy gives us!” Jowy added, gently rubbing his tummy.
“Yep! We had milk too.. Which gives us extra smelly farts!” Jake practically cheered with excitement. Seeing a boy get so happy over farts was strange, but to Jacub it was just another day. 

Before Jacub could even stand up to open a window, because he knew what was coming, Jowy grinned from ear to ear as he lifted his leg, grunted, and let rip a revoltingly wet fart. It flapped on for five seconds, billowing against the seat of his already stained underwear, and filled the air with a vile, acrid stench that had his twin brother snickering and pinching his nose. Jacub, meanwhile, gagged and frantically lunged for the window, yanking it open and sticking his head outside. Both of the flatulent twins frowned and huffed, Jake adding to his brother’s pungent stench by scrunching up his face, grunting, and forcing out a long, bubbly ‘frrrrrrrblblblbltttt!’. It had only been mere minutes and already Jacub’s bedroom stunk of his brothers’ vile farts. The window did nothing to cure that, so he admitted defeat and returned back to his chair. 

As he turned back around, he groaned loudly as he spotted his brothers climbing up onto his bed, Jowy making it up first with Jake not far behind. Unfortunately, the latter struggled somewhat to drag his chubby form up onto the surface and ended up landing on his front with a thud. All the sudden weight on his tummy had the bear squeaking in surprise as his stubby little tail twitched and his rump jiggled as a bassy, powerful fart detonated against his underwear, sending a plume of meaty cub-fart into the room. Jowy erupted into laughter and fell onto his backside, peppering Jacub’s bed with a series of short, rumply poots; ‘frrpt. Brapt. Brrpt.’. Jacub just groaned and buried his head in his paws. 
“Oh come on bro! You’s always so boring!”
“Yeah! You never laugh at our funny tooties!” Jake whined. 
“That’s because you always fumigate by entire damn bedroom!” the older bear replied, clearly fed up with his brothers’ antics. 

Jake and Jowy both lowered their ears and pulled puppy-dog eyes on their brother, trying to get his sympathy, but it clearly didn’t work. The two chubby bears quickly abandoned that plan, shot each other devilish grins, and suddenly scrambled to the top of Jacub’s bed. At first, the older bear was confused, but the moment the two flatulent cubs grabbed one of his pillows each and hovered their chubby, stinky bums over them, their plan was obvious.
“DON’T YOU DA-”
‘BrrrraaaAAAAAAAAAaaapppptt!’
‘Frrrrmmmmmmppppppppptt!’
Before Jacub could finish his sentence, both bear cubs slammed their backsides down, grunted, and launched a flatulent assault on their poor brother’s pillows. Gallons of acrid, steamy gas blasted from between their bubbly, chubby buttcheeks and flooded the stuffing of the pillows, filling them up with the putrid stench of their bowels. By the time their farts sputtered to a finish, Jacub’s pillows were practically steaming with flatulence. With a growl, he grabbed each twin by the scruff of their necks and dumped them carefully onto the floor - even in his anger, he wouldn’t dare hurt his brothers! Jacub then turned his attention to his pillows. He picked up one, grimacing at the butt-shaped indent on the fabric, and sniffed. His face turned green and he gagged, much to the utter amusement of both younger bears. 
“HAH! Maybe now you’ll laugh at our tooties!”
“Uh huh, that smell isn’t gonna’ come out for weeeeeeeeeeeeeeeks!” Jake taunted, punctuating his point by leaning to the side and squeezing out a squeaky fart that reeked of expired milk. 

Jacub had never seen his brothers so terribly gassy before, and the stench was easily the worst he’d ever been forced to endure. He tossed his pillow to the side, and for the first time, yelled at the two troublesome tooters. 
“Get OUT!” he huffed, jabbing a finger to the door. Instantly, both boys froze up, Jowy even letting out a muffled ‘BrMMMMPFT!’ in fear of his brother. Seeing his brother so upset, Jake was quick to the defense.
“HEY! Just cuz’ we’re stinky doesn’t mean you get to be a meany pants!” he growled, although didn’t appear all that fierce. He didn’t give Jacub time to respond as he pulled out a strange device from the pile of clothes he’d left at the door. It looked like some futuristic ray-gun, and it buzzed to life as the chubby bear turned it on. 
“You’ve been told countless times not to play around with mom and dad’s stuff!” Jacub barked, lunging to grab the ray-gun from his brother. Before he could, however, Jake pulled the trigger with his tiny finger.

A zap blasted from the tip and instantly collided with Jacub, sending him hurtling back into the wall. Obviously Jake wouldn’t simply shoot his brother, and he already knew exactly what the device did. It wasn’t a ray-gun, but was rather a shrink-ray! The two boys had tested it out before, and had been looking for the perfect excuse to put it to full use. This was it, and seeing his older brother rapidly start to shrink had Jowy quickly smiling again. Jacub vanished into his own clothes as he shrunk, both confused and terrified by what had just happened. Before he’d vanished, he’d seen the room around him start to grow, and both his younger brothers suddenly seemed a whole lot bigger. So he wasn’t too surprised when a giant paw suddenly wrapped itself around him and pulled him out from the heavy jeans he’d gotten trapped beneath.

Jacub found himself placed back on top of his bed, although now he was only a couple of inches tall. He looked down at his body and growled, turning his anger to the two younger bears.
“Wait until Mom and Dad hear about this! You’ll both be in a LOT of trouble unless you turn me back, right NOW!” he stammered, although the two chubby boys looming above him simply giggled.
“You’re silly bro! We wanna have fun with you first!”
“Yeah, you never ever play with us anymore, so we gotta’ make you the toy now!” Jowy snickered, climbing up onto the bed, his brother right behind him.
“Play? H-how?”
“The same way we play with all of our toys silly!” Jake giggled, poking Jacub with a finger until he stumbled back onto the fart-filled pillow behind him. As he landed, the stuffing literally deflated and a heavy, swampy fog of cub-fart rose around him, forcing him to gag.

“With lots and lots of super smelly FARTS!” Jowy exclaimed, before suddenly turning around and planting his fat, smelly boybum directly on top of Jacub. The older bear gasped as he vanished underneath the undies-clad backside, wiggling and squirming as the hot, musky flesh enveloped him. He found himself slipping almost perfectly between the boy’s chubby, pudgy buttcheeks, face pressed tightly against the fart-stained fabric of his underwear. He squirmed and kicked, but Jowy completely ignored him, simply giggling as he felt his brother rub all over his bum. It wasn’t until a worryingly wet gurgle came from his stomach that the gassy cub stopped smiling. Instead, a look of concentration overcame his face, body tensing up as he slowly started to push. Jacub could feel his buttcheeks squeeze against his body, and through the thin fabric of his underwear, the older bear could even feel his brother’s tailhole pucker outwards and press against his face. 

“Here, let me help!”

Suddenly, the unthinkable happened. Jake had gently punched his brother’s stomach, but it was enough to set him off. The chubby bear squealed as his natural exit yawned wide open, birthing a literal detonation of flatulence. It roared out of him like thunder, gas rippling out from his buttcheeks, and bombarding Jacub’s tiny body with a cataclysm of revolting, hot, meaty fart. Jacub’s body and the pillow did little to muffle the sound, the tempestuous winds billowing on for an impressive twenty seconds, the vibrations of it reverberating across the bed. Jowy’s face became more and more relieved as the immense pressure in his gut slowly dwindled, the boy practically deflating as he battered his older brother’s tiny body with farts. However, even as the mammoth fart splattered to an end, the boy’s bowels had gone too far. Much to Jacub’s utter dismay and horror, and Jowy’s surprise, a far more solid form of stink began to pour from his bowels. 

All his indulgence at daycare had left the cub badly backed up, so he wasn’t too surprised to find his buttcheeks stretched by the head of a fat, squelching log. It rapidly snaked out and pancaked against the seat of his underwear, filling them out with a wet, bubbly splorch. More and more creamy scat rushed out, Jowy’s face scrunched up as he forced out the huge, steamy load. The seat of his underwear sagged heavily against Jacub’s body, engulfing it in squishy, lumpy cub-poop. The fabric quickly stained, oozing with fluids that soaked his fur with moisture. The smell was beyond anything he could’ve imagined, burning his nose with the acrid stench of bear shit. He squirmed as much as he could, but that simply resulted in his brother’s load being mushed around. 
“Oops.. I.. I did a poop!” Jowy gasped as he seasoned his load with a wet, sputtering shart; ‘FRRRRRBLBLBLBLBTTTTT!’

His hefty load bubbled and squelched like a hot mud bath, worsening the stench to eye-watering levels. As it was, the only air Jacub had to breathe beneath his brother’s tushy was fart, but with his air being shit-tainted, he was seconds away from passing out. Fortunately, Jowy lifted himself up, pulling his saggy, lumpy undies off of his brother’s body. Jacub instantly gasped with relief, getting a lungful of fresh air. It was short lived, for the large, pancaked dump in Jowy’s undies quickly peeled away from his butt, forcing his underwear to suddenly sag back down like a pendulum, hitting the older brother square in the face. He winced and crawled away, gasping for air as the soiled bear cub climbed off of the bed and started to panic. 
“Uh oh.. What if Mommy finds out? I dun’ wanna wear diapers again!” Jowy squeaked.
“It’s okay bro! We can.. Uh.. Have a bath! Yeah, we’ll clean up! The grown-ups will never know!” Jake nodded, proud of his smart idea. 
“Ooh! And we can play with Jacub like a bath toy!” Jowy nodded, before waddling off to the bathroom, his lumpy, loaded undies swaying between his legs. 

“Come on bro, let's get cleaned up.” Jake said as he snatched up Jacub in his paws. The older bear didn’t like being carried around by his tiny, four year old siblings, but he wasn’t at all opposed to the idea of a bath, so went along with it without much complaint. He didn’t feel like talking much either, given that the fart-torture he’d just endured left him exhausted. The stench of it and his brother’s dump seemed to stick to his fur - he took one whiff of himself and retched. He needed that bath more than Jowy did! As he was carried into the bathroom, he spotted the other bear cub already in there, standing at the foot of the bath and squirming as he waited for it to fill up. Each time Jowy hopped from leg to leg, a loud, wet fart escaped from his backside, squelching through all the mush inside. Huge, brown bubbles formed in his seat, forcing the underwear to bulge outwards before they popped, releasing their putrid stink into the air. Even Jake had to pinch his nose at the thick, heavy stench of cub-scat lingering in the bathroom air. 

“Phew bro.. You STINK!” he giggled, turning the bath taps off, but not before testing that the water was the right temperature. He wasted no time at all in carefully placing Jacub in the water, who almost immediately dived into it, soaking his entire body with clean, fresh water! The vile stench instantly left his fur, and he felt relieved already. As he swam to the surface once again, the moment he reemerged any relief he had instantly vanished. Jake was climbing into the bath, although like he always did whenever he did so without being picked up first, he was hopping over the edge butt-first. Despite his parents best efforts to stop him from doing such, Jake simply snickered as he suddenly let go of the bath’s edge, and fell back directly into the water! Not only did it result in a huge splash that soaked most of the bathroom floor, but it also had him colliding butt-first with more Jacub! 

The older bear squealed and flailed around, but it only took mere seconds for Jake’s body to plunge him underwater, his small body trapped between the cub’s pudgy buttocks. The cub collided with the base of the bath with a dull thud, wiggling his bum around and completely oblivious to his brother’s current whereabouts. Jacub, meanwhile, was close to drowning, what with there being no air for him! What he didn’t realise, was that he was stuck beneath the biggest source of air in the room, and the fall into the bathtub had stirred it up; his younger brother’s backside. 

“Hehe, gonna’ turn the bath into a jacuzzi!” Jake snickered, before he scrunched up his face and pushed. It took him next to no effort to bombard the bathtub with a powerful, vibrating fart that shook the tub and echoed through the room. Bubbles rippled through the water, fizzing up to the water’s surface and popping, releasing a thick, humid stench. Jacub took the fart straight to the face, and found his nostrils being flooded with pockets of pure, undiluted boy-fart. It gave him air, but the stench was unbelievably foul that he’d rather of drowned! With a few more seconds of air left in him, the tiny, micro-sized bear mustered up what strength he could and pinched his brother’s rump. Jake, as a result, squeaked and instantly shot up, standing in the water, Jacub still pinned between his cheeks. The shock of such sudden pain had his bowels instinctively clenching, which resulted in a wet, popping ‘brrrrrrrrblblblttt!’ as well as Jacub being shot out from between his pudgy moons like a cannonball. 

“Be careful where you sit down, Jake!” Jacub huffed, landing harmlessly into the water. 
“Sorry bro! But hehe, you were like a scuba diver, but you were breathin’ my smelly tooties for air!” Jake giggled, watching as the smaller bear just glared at him. Whilst Jowy was busy cleaning himself off, his twin brother was determined to make their grumpy older brother laugh. He decided to do this by suddenly turning around, aiming his butt towards Jacub and grunting softly. 
“I’m gonna blow you around like a boat!” he remarked gleefully, stuby bear-tail twitching as he gave a hefty push. Sure enough, a loud, roaring fart shot out, sending his cheeks into jiggles whilst a gust of pungent wind shot out from between them. The fart turned worringly wet within seconds, and Jake yelped as he desperately clutched at his cheeks. He tried to stop the fart, but it kept on sputtering out, bubbling through the water and blasting poor Jacub around. 

After fifteen seconds of gas billowing out, the small bear’s cheeks suddenly parted around the head of a large, glistening turd. It flowed out within seconds, plopping into the water and turning the area around it a swampy brown. Jake yelped in surprise and continued to bounce up and down, whimpering as he couldn’t help but push out two move lumpy loads, squelching into the water with audible ‘plops’. Jacub was horrified, especially when a vile, watery shart had those two logs floating slowly towards him! As he struggled to swim away, Jowy giggled and cheered his brother on, to which Jake responded by bearing down and forcing out the last of his acrid dump. It finished with a series of short, sharp ‘brrppt’s and a long, heavy sigh of relief. He twirled back around and sat himself in the water, watching his logs float around, one even pinning poor Jacub against the side of the bath, no matter how hard he squirmed against it! 

“Shall we get cleaned up, bro?” Jowy asked his sibling. Jake pondered for a moment, before he grinned, leaned to the side, and effortlessly forced out a bassy explosion that rumbled through the bath and bubbled the water.
“Nu uh! It’s not a proper bathtime until we have a fart contest! You know that sillypants!” Jake giggled, patting his still bloated tummy. Jacub whined and managed to push himself away from the turd. Before he could even ask to get out, he found the water around him violently rippling and exploding with bubbles, as he was caught in the midst of his brothers’ toot-tournament. There was no stopping them now!

“Worst day off, EVER..” he huffed...
