Most Palamutes were, you know... cute. Or sleek, or elegant. Shin was a giant: shoulders level with Yan's chest, body longer than Yan was tall, and everywhere it bulged with muscle. The straps wrapped around its shoulders and chest were let out as far as they could, and they still strained to fit around the beast's enormous muscles.

Yan swallowed. "You sure he's okay to take out?"

The Palamute trainer guffawed, slapping his thigh. "Oh, for sure! Y'know, this one used to be the runt of the litter! But we took care of him, gave him some extra feed, and now look! A fine Palamute! Our best-trained yet, even!"

Yan looked askance at the giant dog. "You, uh-- you wanna let me ride you?" Yan said, hesitantly reaching out to pat Shin across the shoulder. He snarled, snapping his jaws threateningly, and Yan sagged back, exhaling. "Yeah, didn't think so." He shook his head towards the exit of the forest camp. "Still, we should go," he said, and thankfully Shin fell into a walk beside him.

They walked through the forest. Shin ran ahead and doubled back, stopping to sniff at things, and there was one thing that was difficult to miss. Shin's balls were just as huge as the rest of him: bloated, heavy orbs pulled up tight against his sheath, forming bulky mounds that filled the space between his haunches. Yan flushed. As he stared, he realized that was if anything an underestimation: Shin's balls churned, furry flesh rippling, and his sac loosened from the heat and his prancing walk, sagging downward. His balls had been drawn up so tight they were halfway lodged inside his body cavity; slowly as his sac relaxed they loosened, working their way free until one and then the other lurched downward, spilling out with their full bulk revealed. Yan couldn't believe his eyes: on this giant wolf-dog, each one of his balls was nearly the size of his <em>head</em>, and now with them hanging loose and heavy they swayed and smacked against his inner thighs, audibly clapping against his fur as he trotted along.

Yan wrenched his gaze away from Shin's enormous balls, only noticing then that he'd tilted his head to the side, one gleaming eye staring back at him. A flush spread across his cheeks as he looked away, staring resolutely at the forest brush like he was trying to spot a monster.

They headed deeper out into the wilds, and eventually Yan set up camp for the night -- Yan did all the work, while Shin lay there idly, eyes sometimes following Yan as he fixed them some food. He snapped up an entire beast flank steak in one bloody bite and then occupied himself with gnawing on the bones.

The thing was, with Shin lying there-- it was harder to ignore. The sheer size of the Palamute, the way his heavy balls sagged against his inner haunch as he chewed. Shin caught his gaze, jaws slowly bearing down on a raw bone until it snapped with a sharp _crack_ and Yan flinched backwards. Yan knew what he wanted. He knew what both of them wanted. He crawled forward, kneeling before Shin, and the giant wolfdog got to his feet, sheath jouncing beneath him as Shin pushed his was beneath.

Shin's sheath was an oversized tube that crawled halfway up the dog's stomach, as big and bulky as one of Yan's thighs even with his dick soft and sheathed. Yan swallowed thickly, face flushed as he leaned in, hands stroking across Shin's inner thigh as he brushed his lips across Shin's fat sheathtip. The short, stiff fur buzzed across his lips, giving way to soft, plush skin at the very rim of his sheath, and Yan let out a shaky exhale, groaning into Shin's sheath as he lapped it open: lips pressing against Shin's flesh, tongue lapping inside. Above him, Shin growled encouragingly, rolling his hips forward to slap his bulky sheath across Yan's face, smearing him with rank sheathfluid. Shin tasted acrid, skin bitter and meaty, and Yan groaned, dimly aware of the throb of his own cock as he licked into the dog's giant sheath. He sloppily licked his way into the heavy sheath, tongue scraping off congealed murk from the inside of Shin's sheath, bursting bitter and overwhelmingly potent in his mouth, so rich he gagged and drooled, spitting the mess right back into Shin's sheath, only to have the mess gurgle back out all across his face, painting him in frothy lines of dog slime.

Yan's fingers clenched, digging into Shin's muscular haunches as he gasped for breath, blowing slimy bubbles of rank-smelling ooze. Shin's sheath gurgled, stringy ooze spilling out in heavy cords that splattered to the ground beneath his legs.

The flesh of his sheath warped, fattening, and with the force of a punch the tip of his enormous dog dick slurped out into the open and bashed against Yan's face. His cock was a mottled purple-red, already streaked with rippling layers of frothy slime from the mess Yan had made of Shin's sheath, and as more and more gurgled out into the open Yan's eyes got wider and wider. Shin's cock wasn't just huge, it was a monster all on its own: it spanned from between his haunches all across his underbelly, bloating fatter in the middle and tapering near the base, leaving his sheath oozing slime along the underside as it gaped after pushing out the fattest point. The soft, turgid bulk of his knot was visible across the base of his shaft, a mounded swell already as big as most fully-engorged knots he'd seen, but here the flesh was soft and pulpy, completely flaccid even with its bulk the size of Yan's own head.

Fully unsheathed, Shin's cock jutted out past his forelegs, drooling slime all across Yan's back and drizzling into the dirt behind him. Yan flushed, socketing his head into the sloppy mess behind his knot: face pinned against his soddens sheath, Shin's heartbeat echoing in his ears from where he was jammed against his enormous knot. Slime wetly drooled across his shoulder, oozing down his body as he kept lapping at Shin's blown-open sheath, wetly huffing between gulping down heavy, reeking mouthfuls of gummy sheathfluid.

Yan dragged himself back, face smearing all along Shin's shaft, until he was crouched in front of Shin, staring at the very tip bobbing just beneath his neck. Shin let out an eager growl, muzzle hanging open to give Yan a slobbery lick across his face, adding a mess of drippy dog saliva to the mess painting his face. Yan panted hoarsely, mouth clogged with slime, and Shin slopped his tongue over Yan's lips, shoving it into his open mouth and plunging it down his slime-lubed throat, opening wide to take Yan's head between his jaws as he plugged Yan's throat with his tongue, flooding his mouth with frothy dog drool.

Yan gurgled, spitting up slime around the twisting muscle of Shin's tongue as the dog tonguefucked his throat. Ooze squirted from his nose and mouth, slobbery strands of frothy drool. Shin rutted forward, sending his mammoth cock slapping against Yan's chest, painting him with drool and pre, utterly drenching him in the dog's slimy issue. When Shin pulled back Yan looked drugged: eyes blown, expression slack, spit oozing out over his lower lip. He dazedly groped forward, hands curling around Shin's enormous cocktip, and he gave it a sloppy pump, groaning wet and guttural as the shaft twitched in his loose grip, letting out a squirt of pre that sprayed all across his front. 

Yan lapped cords of pre out of the air, letting the excess splatter over his lips and pour down his front as he started to stroke Shin's cock. It was so huge, so impossibly rich and virile -- a single spurt of pre was a half-dozen of Yan's loads, splattered all over his front and coating him in the dog's rich essense. Yan moaned, opening wide to try to cram his mouth over Shin's cocktip -- mouth overflowing, ooze squelching between his teeth and lips, tongue clotted and heavy with sludge. Shin rolled his hips forward, fucking his colossal cock along Yan's face, smacking him heavily over and over with his brutal length, splattering reeking dog slime all over until his entire body was dripping and drenched, skin shiny with a glossy layer of translucent slime. Yan stroked Shin off in a daze, hungrily swallowing down mouthful after mouthful of watery slime until his belly ached, sloshing and heavy.

Shin bayed, howling at the sky as his cock lurched hard and hosed Yan down with his heavy load: spurt after spurt of opaque white cum splattering across his face, gurgling as it poured into his open and needy mouth, utterly soaking him in dog cum until he resembled a shrouded figure, pale white and dripping, coated in free-flowing layers of rank dog cum. Shin's cock thundered, lurching like a cannon firing, sending each fountaining blast of cum lancing across Yan's face, chest, stomach.

Yan's fingers were sore from gripping Shin's mammoth shaft; his lips were raw and aching from the stretch of trying to curl around even just his cocktip, body glazed in runnels of soupy dog cum. Shin yapped at him, tail eagerly wagging as he rutted his sluggishly-drooling cock across Yan's chest, smearing the mess of slime back and forth across his glazed body. It was the first time Shin had seemed pleased with him. If this was what the dog was expecting from their partnership -- Yan flushed, feeling heat pool in his belly as he stared at Shin's sluggishly-retracting cock, spilling immense clots of grimy dog cum to the churned-up ground below. Well. He could do worse. Maybe next time Shin would let him take his dick.
