to preempt the inevitable "red xiii is more like a lion than a wolf" debate i gave him barbs AND a knot. this should make everybody happy.

originally this was gonna have SOME setup but then i started writing halfway through a sex scene and just didn't stop, so,

He stroked, the sandpapery flesh of Red XIII's cock catching on his fingers, making him pant, hips jerking minutely forward to rut his shaft through Cloud's loose grip. He was twisted up, shaft scraping up and down his side, stroking awkward, and so Red XIII huffed, his puff of breath rolling across Cloud's side, and straddled him: unsheathed cock pressing against Cloud's stomach, smearing slimy fluid all over his skin.

Fully unsheathed and erect his cock had to be at least a foot and change long: half-exposed knot bulging the flesh of his sheath, shaft covered in tightly-spiralling lines of stubby barbs, tip flaring out to a sharp, thin-edged cockhead, where the barbs grew to immense, thorny prongs, already catching and rasping across the flesh of Cloud's stomach. Cloud's cock was buried under Red's balls, leaking pre over his fuzzy sac, his hips dimly jerking up, sliding his smooth cockhead through a tunnel of flesh, lubed by his own pre.

Red panted, tongue lolling from his mouth, drool spilling across Cloud's chest, and he leaned in, licking a slobbery stripe up his cheek, stuffing his tongue into Cloud's mouth, muzzle opening wide to kiss him. Cloud groaned, sputtering out their mingled spit, foaming at the edges as he sucked on Red's tongue, both hands stroking his giant cock. Red's cock pulsed in his hands like a gun firing, a gush of pre erupting up across his chest, splattering across his neck and the underside of Red's muzzle, soaking his mane into heavy tendrils. More pre gushed across Cloud's chest, sheening him in watery slime, spilling down his sides.

Red pulled back, tongue slithering from Cloud's mouth to spill drool all across his face, Cloud wetly gasping for breath, and then Red took a half-step back, cock pulling back through Cloud's grip, sliding down his stomach. Red's hind legs pressed against his thighs, and Cloud raised his legs, letting Red's cock slide down, tip digging into his ass. Red bucked, cock swinging, splattering his ass with droplets of pre before his cockhead skidded over his skin, tip bearing down against his tight asshole.

Cloud settled: legs slung up over Red's haunches, riding him upside-down. "C'mon," he said. "go hard; I can take it. Mako treatment."

Red looked down at him, tail lashing wildly behind him, his cock spraying Cloud's upturned ass with pre, and then he drove forward, plunging nearly half his mammoth cock into Cloud in a single brutal thrust, instantly sawing back and forth, his big fleshy barbs tugging and pulling on the inner flesh of Cloud's ass. Red went hard, not a pause as Cloud howled, hissing; he kept thrusting, breaking him open. His knot was already half-inflated: sheath bulged hugely around the trapped knot, only the upper crest peeking out. Red snarled, thrusting deep, going nearly deep enough for the sodden fur of his sheath to scrape over Cloud's ass.

Cloud reached out, squeezing his sheath, tugging down until Red's knot shoved out with a _slurp_, sheath wrinkling up under the heavy, meaty crest of his knot, visibly shuddering and swelling. He slammed forward, knot crashing against Cloud's hole, and drew back, each thrust plunging a few inches deep, ending with his knot spanking against his ass, rocking Cloud's body. The impact sent pre erupting in all directions, thicker cords webbed around Red's knot, sticking to Cloud's skin on the impact and stretching in goopy strings when he pulled back.

Red was panting freely, fur soaked with sweat, hunching in harder and harder thrusts, knot slapping against Cloud's stretched hole and bearing down, the pulpy half-inflated flesh of Red's knot squelching and squeezing, dragging in fractional jolts. He had barbs along his knot too, sandpapery dragging up and down the raw flesh of Cloud's hole, shoved half inside. Red growled, yapping and roaring, hammering into Cloud's unyielding ass in erratic jerks, his paws scrabbling on the ground to get better traction. Finally he ground down, paws digging and digging, hips wiggling, working his knot back and forth: left half skidding a fractional inch in, then the right, back and forth even as his knot kept swelling further. Even with most of it in, Cloud's asshole loose and gaping after the thickest crest shoved in, there was no respite: past his asshole Cloud's ass was still tight, flesh clinging tight to the sandpapery flesh of Red's dick as he forced the rest of his knot in, sheath piling up against Cloud's hole as his oversized balls finally came crashing down over his upturned cheeks, hilting the full length of his cock.

Cloud sprawled back, hissing with each slap, his eyes half rolled back into his skull, his cock drooling out a filmy wash of mingled pre and come as he took each thrust. He panted, mouth open, Red lapping across his face, shoving his tongue into Cloud's open mouth as he strained to fit his knot in. Red howled, baying loud as his knot surged, fatter and fatter, and then bowed his head down, brutally plundering Cloud's mouth, tongue shoving its way inside, drool flooding his mouth and overflowing his lips as Red shoved his tongue down Cloud's throat, hips uselessly wiggling, just tugging his knot back and forth minutely where it was lodged in his ass, stirring his entire dick up and down in Cloud's guts.

Locked in place, the thick, tarry squirts of come slowly turned into something slower and more continual, almost like Red was just pissing come directly into his ass. Cloud sagged back, dazed and panting, skin flushed and sweaty, the fat bulge of Red's cock up his stomach already starting to soften and sag as his guts bloated with the rest of Red's load. His own cock was drooling come, prostate crushed flat under the sheer bulk of Red's knot, keeping him not-quite coming.

Red twisted, dismounting, and his cock pivoted in Cloud's ass, barbs and sandpapery flesh latching deep into his guts and twisting them with it. Red flipped around, cock pulling back between his legs, shoving his heavy hanging balls to the side, pressed ass-to-ass with Cloud, cock endlessly tugging out, knot grinding hard against Cloud's splayed asshole. The extra pressure on the knot kept Red coming, gush after gush of watery pre spraying all across Cloud's insides, gurgling its way deeper until his stomach audibly sloshed with each tug, flooded gut churning as come drenched his insides, swollen and heavy and bulging out from his lithe body.

Red's paws dug into the ground, gravel scraping under his claws, and bodily drug Cloud forward, knot seated solidly enough to drag him around, the extra pressure clamping down hard around his knot making him erupt, sudden hot gushes of come spraying hard, only slowly subsiding back to the usual slow pour, flooding Cloud up with his load until he looked pregnant, belly bloated and straining, wobbling with each of Cloud's straining breaths.

It was ages until he stopped gushing, and another few minutes after that until his knot finally started to soften -- but nearly instantly he popped out, dragging Cloud another half-step further, his entire ass bulging out around the wreck of his spread asshole, the wrinkled flesh bloated and bruised. Red pulled out with a soggy _thlop_, knot and then half his barbed shaft jerking out into the open, absolutely drenched with his load, spilling in rivers down his shaft from Cloud's wrecked ass. Cloud flexed his hole, hot pain burning up his spine, and the huge cratered hole flexed and slurped, broken rim fluttering tighter around Red's shaft for a half-second before it gaped even wider, come gushing out of him as Red dragged the rest of his cock out, swinging low between his legs before it smacked across his stomach, splattering thin, watery come everywhere. With Red out of the way Cloud could finally lower his legs, thighs trembling, abused muscles going slack as he rolled to the side with a groan. He closed his eyes, only aware of the pulse of come flooding out of him, a watery gush spilling from his broken ass in an unending stream, soaking his sides and puddling under him.

Red stepped around him, half-hard cock so thickly slathered with come it looked like he was still coming, ribbons of come dripping and drooling down his length. He mounted Cloud's face, come-coated cock slapping over his cheek: "Open up," he rasped, and rutted forward, smearing Cloud's face with come, forming slimy rivers across his brow, streaming down his cheeks. Cloud obligingly opened his mouth, Red's cockhead immediately shoved inside, and he suckled on the tip, softening flesh pulpy and heavy as he lapped at the soaked length, drinking down a messy slurry of come.
