Brown-Noser

Laying in his bed, Logan tossed and turned with a mischievous smirk on his face, too amped up to close his eyes even though the moon was shining just outside of his window and he had a full day of school ahead of him tomorrow. Just yesterday, the young grey wolf had caught his little brother right in the middle of a very private moment, peeking in on Owen huffing on a pair of underwear smeared with his brown stains, taking care of an erection at the same time. He'd had his hunches about his younger sibling secretly loving his musk for quite some time now, noticing the subtle changes in Owen's behaviour over the months whenever he'd pin the squirming little pup against the floor and introduce his dirty tailhole to the cub's face, but Logan hadn't actually had any concrete proof of his suspicions until spying on Owen painting the floor with an impressive load while the dirty pair of underwear was wrapped around the boy's muzzle. Flopping onto his back and sighing softly as he squeezed the bulge hiding underneath his blanket, Logan wasn't entirely sure what exactly he should do with his newfound discovery. He certainly could've simply barged right into Owen's room and shoved the puppy's face between his muddy ass cheeks, taunting his little brother about how he knew for sure that the cub was loving it, and he probably would've done exactly that if it weren't for their parents lounging in the living room downstairs. The need to wait for a good time to strike did however give Logan the opportunity to think over his plans slightly, letting him come up with a slightly different approach to the situation, something a bit more subtle and fun. Instead of confronting his sibling right away, the boy instead decided to make Owen come to him, his devious plan forming in his mind as he giggled and massaged his knot through his briefs, the back of the previously white pair already sporting a small smear of brown as his stomach gave a threatening gurgle, his blanket trapping in the gas as his tailhole flexed open to release some of the pressure brewing in his gut. He made a mental note to not use any toilet paper for as long as his plan was ongoing, already looking forward to the greasy morning dump that was marinating in his belly as he closed his eyes, finally settled down enough to at least catch a little shut-eye before having to wake up. 

Flinching slightly as his alarm rang, Owen opened his eyes and reached to shut off the ringing clock as he peered around his room carefully, trying to spot any signs that his older brother might be trying to ambush him, having learned from experience to always stay on his toes even when he thought he was safe. His usual dread and anxiousness wasn't there however, instead replaced with slight thrill as he scanned the room, his nose twitching as he sniffed the air, his hands tamping down the blanket over his crotch to hide just how excited he actually was at the thought of Logan jumping out at him from the shadows, pinning his head against the pillow and forcing him to huff the foul results of the boy's morning dump. For once, Owen felt faint disappointment at his room being empty, no sign of the older canine hiding in his closet or crouching at the foot of his bed, only his favourite plushie cuddled up against his side, still cloaked in a faint musk from repeatedly being used as Logan's toilet paper in an attempt to taunt him. Laying in his bed for a few minutes longer, Owen heard both of his parents leaving for work, a jolt of nervous excitement getting him out of bed as he stripped off his pyjamas, replacing his clothes with a towel tied around his waist to hide his morning wood. He pressed an ear against his bedroom door, trying to listen in as he swayed and fidgeted in place, too worked up to stay still, taking a deep breath as he grabbed the handle. The pup hoped that maybe Logan might try to ambush him now that their parents were gone and they were alone, stepping out into the hallway with an overly innocent look on his face, his smile fading more and more with every step as he strolled towards the bathroom, stepping in with a frustrated groan, disappointed at having gotten there completely unmolested. The cub hadn't been assaulted by his big brother ever since his held back desires had come to the surface and he jacked off to the brown smudge that he wiped off of his own face, annoyed that Logan had mysteriously chosen to leave him all alone the second that he actually would've wanted to be buried underneath a sweaty and soiled flank. Grumbling as he tossed off his towel, the boy marched into the shower and cranked it on, turning it as cold as it could go, hoping that it might ease the stiff shaft throbbing against his belly before he had to go to school. 

With his older brother having already left by the time he stepped out of his cold shower, Owen didn't have much to do besides quickly drying his fur and getting dressed, grabbing his backpack and stepping out of his room, just about to gallop downstairs when he stopped at the door to Logan's room. Nudging the door open, the cub couldn't help but to take a sniff of the stale air, still stinking like a backed up public bathroom even with the dirty wolf having already left. Shuddering as he clung to the doorframe and inhaled the foul scents, Owen managed to shake off the trance after a few minutes of soft moaning and grinding his palm against the front of his jeans, snapping out of and glancing at the time, quickly running down so as not to be late. Jogging half of the distance to the school, the young canine made it just in time, arriving at his classroom just as the teacher opened up the door, slumping into his seat while panting, still nursing a half-chubbed erection. Owen's morning at the school went by completely uneventfully, much to his chagrin, his heart jumping with hope every time he stepped around the corner, desperate to be "surprised" by his older sibling and getting a faceful of reeking ass. After the first break came and went with no Logan sight, the cub decided that he needed to be more proactive, doing his best to spend as much time as he could in the bathrooms, at the locker rooms, behind the storage shed at the yard, and anywhere else where he'd be entirely alone and the risk of getting ambushed would be high, hoping that he could draw his brother in. With lunchtime arriving without the stinky torment he was desperate for, Owen was only frustrated even further, now needy enough to actively try to seek out his sibling. Skipping lunch entirely, he scoured the school in search of the deviant canine, keeping both his eyes and his nose peeled for his brother. After a few minutes of searching around, he finally caught the older wolf slipping into the school library, following the boy inside. Already aware that he was being followed, Logan acted completely nonchalant, trying to seem busy as he grabbed a book from one of the shelves before taking a seat in front of one of the computers, rocking to get comfortable in the computer chair as his little brother hopped next to him, tapping him on the shoulder with a shy smile, 
"Hey, I… I don't really have anything to do until next class, wanna hang out… or something?"
"Sorry, but I've really gotta get this project done before the end of the day."
Logan could see the smaller puppy's disappointed expression as he rolled his chair up to the computer, flipping open the book and clicking at the keyboard as he looked down, burying his muzzle into the book to hide his smirk. 

Though let down, Owen decided to stick around at the library until the beginning of his next lesson, praying that the diabolical canine might be tempted into jumping him sooner or later, slumping down into a seat a few desks down from his brother, unaware that he was being surveyed the whole time. Pretending to read his book and work on the computer, Logan kept one eye on his little brother, making sure they were alone and that Owen wasn't looking towards him before putting the second stage of his plan into effect, hoping to tempt the cub into getting more desperate for him. Slowly and gradually turning his chair until his back was angled towards the little pup, Logan stealthily shuffled his shorts and underwear down just enough to expose his crack, a miasma of stench almost immediately surrounding him. Holding back a moan, he leaned to the side and slipped a hand underneath him, pulling his cheeks apart and slamming his soiled hole against the soft and absorbent padding of the computer chair, making sure his dirty pucker was properly squished against it before rubbing his donut all over it, panting softly as he wiped his asshole. Trying to carefully control his hole, he let a steady and quiet stream of gas spew onto the soft seat, sighing before pulling his pants back up again, slamming his book shut, 
"Can you watch my spot for me? I gotta go run to the teachers' office for a few minutes." 
Logan dashed off, stopping right behind the corner as Owen stood up, following his nose as he picked up the familiar scent that made his nostrils burn and his eyes water, his jeans tenting as he peeked at the chair to find a brown streak right down the middle of it, still damp. Immediately dropping to his knees and shoving his face against the soiled cushion, Owen reached a shaking hand down the front of his pants, rubbing his cock through his underwear as he shuddered and moaned, huffing the fetid stench absorbed by the seat. Poking his head around the corner, Logan watched with a wide grin as the boy dragged his tongue across the stain, whimpering and rubbing his muzzle on the soiled spot while jerking off, his tail standing up straight as he exploded in his briefs, soaking his underwear in jizz as he whined and suckled on the wet fabric. Panting, Owen pulled his cum-covered hand out of his sticky briefs as he quickly stood back up, wiping the load on the back of his jeans as he looked around with a heavy blush, just barely missing his older brother ducking back behind cover as he ran off to get cleaned up.

Getting home after school, his balls considerably lighter but his desires still not quite satiated, Owen found his older brother already lounging around in the kitchen, their parents still at work and probably not home until at least a few hours. Though Logan had wiped his tailhole on the school's chair, his backside was still filthy enough to immediately grab hold of the younger cub's nose, especially after he'd had a long and thorough emptying of his bowels shortly after coming home, his underwear soaking up most of the unwiped muddy mess he'd left clinging to his fur after. Sitting at the dinner table, working on his homework with a focused look on his face, Logan muttered out a hello at his little sibling while chewing on his pencil, his butt pushed all the way back in his seat and his upper half resting on the table. Owen stared at his brother's flank pushed right up against the open backrest of the chair, the boy's plump ass beckoning to him, the musk growing thicker with every step he took towards the scheming canine. Trying to hide his growing erection underneath his shirt, Owen hesitated for a moment before pulling a pack of gum from his pocket, dropping a piece on the floor and blurting out an exaggerated yelp as the red on his face deeped, 
"O… oh, whoops!" 
Getting down on all fours to look for the piece he'd deliberately dropped, acting as if it had rolled underneath a cabinet right next to his brother, the cub took the opportunity to stick his nose right up to his older sibling's ass, just barely able to keep himself from shoving his face right into the stinky mound as he bit his lip, trying to force himself to be satisfied with just sniffing the back of Logan's shorts, imaging the soiled cheeks slamming down around his snout once more. Lingering behind the bigger wolf for almost a minute, Owen finally stood back up, running into the bathroom without a word, leaving Logan to stifle a laugh as he heard the door lock and the boy's pants dropping to the floor a second later, soft panting and puffing coming from under the bathroom door. 

Making sure that the cub huddled inside of the bathroom could hear him, Logan got up from his seat and headed upstairs, quickly stripping down and tossing his clothes aside, leaving his soiled briefs right in the middle of his bed, immediately in sight from the door that he left ajar as he headed to the shower. Downstairs, Owen had his shirt pulled up and tucked into his maw to muffle his whimpers as he fondled his knot, his ears perking up at the sound of the shower turning on upstairs, the patter of water giving the lust-crazed boy an idea. Hurriedly stuffing his erection into his open jeans and tugging his shirt down, the cub stepped out and snuck upstairs, slowly climbing the stairs on all fours to make sure his big brother truly was in the shower, his head peeking up as he held his breath. With the way clear, he dashed into Logan's bedroom, his eyes bouncing around for a second before settling on the big prize the pup had hoped he'd find: his sibling's underwear. The previously-white briefs were now mostly stained light brown after days of sweat and unwiped dumps, the heaviest blotches of mud appearing at the back, a few specks of dried and not-so dried shit still clinging to the weathered fabric. Immediately falling in love, Owen sprinted over and snatched up the undies, turning them inside out and ramming his nose into the nastiest spot, moaning as he smushed the pair on his face, using his hand to simulate Logan's weighty ass rubbing and grinding on his muzzle as he dropped his pants, almost cumming on the spot as he sniffed and licked at the messy pair. Realising he was still danger of being discovered, the cub pulled the underwear off of his face, leaving behind a streak of shit along his snout as he stuffed the briefs into his own underwear, letting them soak up his precum as he quickly waddled into his own bedroom to unleash his lust, completely missing the fact that the shower turned off only seconds after he slammed the door shut. 

Stepping out of the bathroom, Logan stalked along the hallway towards his little brother's bedroom door, the sounds of ecstatic moans and grunts growing louder as he approached with a naughty smirk on his face, still entirely naked. Grabbing onto the door handle, he carefully inched it open by just a sliver, hoping it wouldn't squeak too loudly as he  gripped his shaft with the other hand, licking his lips as he peeked through the crack. Thankfully for the young voyeur, Owen was far too enchanted by the musky pair of underwear to even notice anything going on around him, his clothes hurriedly ripped off from the waist down as he sat at the edge of his bed, jerking himself off while inhaling his brother's stench, his tongue cleaning up the dirty stains as his lungs filled with all of the noxious gas that the briefs had absorbed. Wrapped up in ecstasy, the boy didn't see his bedroom door slowly opening wider, just barely catching a figure with grey fur standing up in the corner of his eye before he was tackled, his face still buried in the disgusting undies as he was pinned on his basic to his bed, his arms trapped against his sides as he yelped. Logan peeled his briefs off of his little brother's face, grinning down at the shocked and terrified pup while giggling, letting his tip grind against Owen's soft belly as he dangled the stolen pair over the cub's head, a free drops of drool dripping from the saliva-soaked underwear, 
"I guess you really do love sniffing my butt, huh~" 
Too embarrassed to even attempt to say anything, the boy simply stared up at his older brother in silence, his face bright pink, his dick still stiff and spurting precum, having been seconds away from popping his cork before he was interrupted. The older canine tossed the cleaned undies to the floor, smirking as he slowly turned around, watching his sibling's eyes widening as he parked his flank right above Owen's face, spreading his cheeks and teasing the kid with a little wiggling, 
"Well, if you like my undies so much, maybe you'd like the real thing even more~?" 
Owen nodded sheepishly, but Logan wasn't about to give him what he needed without first making him work for it, 
"Nuh-uh, you gotta say it, say that you love my butt~!" 
"I… I love your butt…" 
"And that you wanna sniff my stinky butt~!" 
"I wanna sniff it." 
"What else~?" 
"I… I wanna lick your butt, I wanna kiss it!" 
"Good boy~" 

With his brother properly humiliated, Logan finally planted his ass where it belonged, shoving the hungry puppy's muzzle between his ass cheeks as he shook his flank to get into a comfortable position, already feeling the cub's tongue tickling his taint as he grabbed his own shaft, giving it a few pumps while riding on the smaller wolf's face. Suffocating on his big brother's ass, with shit smeared across his nose and lips, Owen moaned hard and licked at the muddy undercarriage, splatters of scat clinging to Logan's crack, taint, and even balls. Trying to leave no inch untouched, the boy swabbed his sibling's backside as clean as he could get it, letting the flavours and scents overpower him as Logan grinded the ass on his face, barely letting him get a single breath. In search of more of his brother's delicious musk, Owen's tongue soon began prodding at the entrance of the devious canine's tailhole, tracing the rim before sinking inside, letting the pup experience the most concentrated stink he'd ever smelt, almost knocking him out as brown sludge coated his tongue. Huffing as his little brother rimmed him, Logan laughed as he watched Owen's cock twitching and quivering, the puppy's legs kicking the air before the boy came hands-free, ropes spraying up in the air and splattering both of the wolves as Owen squirmed and whimpered, completely trapped until Logan had also had his fill. Shoving his little sibling's tongue as deep as it would go, letting it tickle his prostate, Logan gasped and added to the creamy coating already staining the cub's belly, his orgasm causing his hole to spasm, a few short farts blasting his younger brother's face as he emptied his load before pulling out, turning around to see Owen's face painted almost entirely brown, 
"You're such a brown-noser~"
