#4 of Commissions

this was a commission for user tehsean over on furaffinity, and apparently Nao here on sofurry!!

there doesn't seem to be a good tag for "cock interpenetration". 'sounding' just doesn't cut it.


Naoki walked up the path. It was difficult to move; he had to spread his legs, walk bow-legged to avoid smashing his oversized nuts between his thighs. He wasn't used to their new jostling weight, swinging freely. Their newly-stretched skin made them bounce and jolt with each step, sending a not-unpleasant ache across his body, up his stomach.

His cock was just as bad, his shaft bouncing in front of his balls, slapping across his thighs, still wet with come and already drizzling fresh pre. His cock smeared wet trails across his knees as he raggedly climbed uphill. He was still a little dazed, dizzy from the orgasm, and from the immensity of what'd just happened to him, his cock suddenly an enormous pillar between his legs, bigger than anything he'd seen or even heard of.

And, yeah, he wanted more, wanted to see if it'd get even bigger. Just that thought, moreso than even the physical sensation -- the wet, slick slide of his cock against his damp flesh -- was what was making him hard again, cock stiffening in minute jolts, engorging fat and hard as he walked, even though he'd blown out what felt like gallons of come just minutes ago.

Going was slow, practically just crawling upwards -- straining to drag his balls with him when he stepped up a slight staircase of roots; holding overhanging nettle-bushes back as he inched around them -- trying to avoid all sorts of new obstacles he hadn't even noticed on his way up. His cock was drizzling pre, sharply-scented, smearing over the bulging curve of his balls and dripping to the ground, leaving a thin dark line in the dirt behind him.

Flushed and naked, he staggered to a stop, leaning against a tree to catch his breath and give his balls a rest, his sac aching from the constant stretch. The canopy was still raucous with bird cries, all the verdant nature seeming a little dissonant now with what he was dealing with.

All his thoughts of a relaxing week away gone, replaced with vivid thoughts of a week spent exploring his new cock, seeing if he could coax it even bigger. His cock plumped further at the thought, the immensely fat shaft twitching upwards, and he sagged back heavily, a breathy sigh escaping his lips. He slid his hands over the immense curve of his shaft, veins bulging all across the surface, pulsing slowly. A huge dewy drop of precome gathered at the tip and dripped down, the liquid hot as it curved over his balls and splashed against the ground.

Not even ten, fifteen minutes, and he was already more than ready to go again, pleasure throbbing through his veins, fogging his mind, until all he could think about was the dizzy heat between his legs, the heavy throb of his cock.

Still, dimly, he noticed when the bird cries died out. He looked up, head lolling almost drunkenly. Seeing nothing but the thick ferns, low branches bordering the trail, he looked back down at his cock. It was bobbing between his thighs, fat and stretched-out, shaft bloated near the tip, his new flesh sagging under its own weight.

He grabbed the base and squeezed. His cock went rock-hard, then bloated outwards slowly, pink-white skin flushing dark red as some new internal pressure forced it larger. It grew in shuddering, snapping bursts as he grasped down hard along the sides of his cock, stroking back and forth in minute degrees, slowly -- somehow -- stretching his cock further. It bloated thicker and fatter, heavier and heavier between his thighs until it came to rest as a titanic weight over his balls, achingly hard but just so huge it couldn't even stand upright under its own weight.

There was a rustling in the bushes, and his head snapped up, staring -- eyes unfocused -- at the moving leaves. The rustling paused, and then something leapt out, a brightly-colored blur that slammed into his side. The impact knocked Nao over, down onto his ass, the immense spanning body of the -- person? -- pinning him to the ground, even beyond the sheer weight of his balls and inflated cock anchoring him in place.

The contact all along his side and front was heated, wet and dimly-sticky, his cock slapping up across his chest as he sprawled onto his back, cockhead heavy and soft wedged against his neck. There was a mouth open and licking against it, wet and rough, giving a rasping friction that sent him gasping and squirming, trying to thrust up into the wet heat of the person's mouth.

The overwhelming impression was heat, sticky and moist, boiling off the other man's body like he was a furnace, practically rippling the air around him, heat and weight all over his body from when the man was lying practically atop him, head bowed to lap over his cockhead and neck in the same heavy wet stripes. Nao's eyes were swimming, head dazed, and he found himself uselessly grinding against the muscled planes of the guy's body, hands scraping over heavy cords of muscle, fur thick and shaggy.

Focusing enough to actually look at the guy, resolving the bright smears of red and gold into shapes, Naoki just stared. He was a lion, and not just in the way the guy who worked at the hardware store back in the city was a lion. Dimly, he felt he should sit back, think about it, but all he wanted was release, the hot desire cresting in higher and higher waves as he sunk into an aroused haze, the lion's scent thick and musky, somehow still sweet and tart as Nao pressed his face against his neck and inhaled. His entire body shuddered at the potent smell, sweet and rich, with a heavy, rough tang underneath that went straight to his cock.

The lion guy looked like a wild animal, not like some other camper -- not even like some other camper who'd been stranded for a year. His hair was in a shaggy mane, all red-gold in congealed hanks around his face, spreading over his shoulders and down his back. And the muscled slope of his back was closer to the four-legged kind of lion than anything bipedal. He was hunched forward, legs bracketing Nao's thighs, and almost on all fours, his legs tense and outstretched, like he'd be just as comfortable on all fours. His paws -- hands and feet -- were stubbier, thicker than most guys, and tipped with wide claws.

That was part of what made him so unusual. The other part was that he was translucent. Mostly near the edges, almost opaque at his core, but still hazily see-though in parts. His body was lean and sculpted, fur not more than thin stubble, aside from thicker patches of burnished red-gold fur -- his mane, over his forearms, down his chest, in whorls over his hips. Elsewhere he was a vividly-bright lemon yellow, flecked and streaked with shots of gold. But none of it was quite fur or flesh -- or muscle -- but something like gel, solid and spongy. Even in the slow, heavy churn of his muscle Nao could see the lion's substance bunch and move, bunched cords rippling below the surface of his body.

He was also immense, muscles like solid blocky chunks, rippling along his tightly-defined form. He slobbered across Naoki's cock, dragging his tongue down the bloated line of Nao's shaft, dragging his nose down his stomach. His legs were getting soaked, the lion's dick was spurting hot musky precome in wet floods across his thighs; what had to be the guy's cockhead dragging every-so-often against the curve of his balls, sharp-tipped and hard.

The guy pressed his muzzle against Naoki's cock, lapping up sweat and pre and leaving his skin even more sticky. Everything the guy did was a little too springy. The lion yawned too-wide, the sloppy wet heat of his mouth spreading wider around his shaft as he dragged his head up, until he enveloped Nao's entire fat, flaring cockhead; his tongue pressed against the underside of Nao's cock and flattened, stretching out until he was licking in a wet, rippling rasp all along his cockhead. Even his muscles, as the lion hunched forward, practically humping his balls, his entire body seemed to compress at the apex.

"Hey, hello," Nao finally managed, between shuddering moans, hips trying to move under the bulk of his cock, rutting his head back and forth inside the lion's distended mouth, gel-body stretched almost translucent around the fat girth, his pre visibly pooling in the back of the lion's mouth between swallows.

The lion let out a growl that could've been a hello, rumbling deep in his chest, vibrating all along the underside of Nao's cock, and he let out a high whimper, cock unloading a heavy spasm of pre, distending the lion's neck before he swallowed it, thickly.

Naoki gripped the guy's shoulders, gel bulging out around his fingers as they ever-so-slowly sunk inside. The lion pulled back fractionally, his shaggy mane -- gel in wavy hanks all stuck together -- draping back so that Naoki could see the guy's face. His muzzle was striped red-gold, and stretched almost unrecognizably, face warped around Naoki's immense cockhead. All he could do was gasp raggedly as the lion sucked him off.

The lion's huge paws wrapped around Nao's hips and dragged him forward, muzzle spreading, throat bulging as the length of Nao's cock slowly sunk deeper inside him, outlined in a sheath of gel, almost transparent where it bulged fat and heavy in the middle of the guy's throat. He could watch every little movement, cockhead flaring inside him, fattening, his veins popping to the surface as the lion bobbed back and forth on his cock, soggy growls vibrating through his body as he slurped back and forth on Nao's cock.

And -- the lion's own cock dragged more and more insistently against Nao's balls. The lion was sprawled atop Naoki, keeping him pinned simply from the weight of his immense body -- not that he needed to; Nao could hardly move under the weight of his own cock, and he sure wasn't trying to escape; eyes rolled back, mouth open, cock flexing deep inside the lion's throat. Through layers and layers of gel-muscle he could just barely see the vague shadows of the lion's cock through his back, a piercingly-vivid cherry red peeking out from his sheath -- the whole length of it visible inside him, straining against muscles as it slowly pushed outward.

The lion's ragged thrusts were splashing precome all across Nao's bloated balls, sugar-smelling and tingling, soaking into his flesh and making it even softer, supple and stretchy. He rutted, unsheathing cock pushing up to smash against the base of Nao's shaft, rubbery cocktip deforming as he rocked back and forth through the wet, glistening furrow of flesh between Nao's oversized balls.

Nao, dazed, could only take it: pinned down, immobile, hands clenching inside the lion's shoulders, mired up to the wrist in rubbery folds of gel. He whined, high in his throat, uselessly trying to spread his legs even wider for the lion. His cock throbbed, the red-tinged stream of pre shining in the sunlight as he pumped it down the lion's throat, forming a thick reservoir inside his body. The lion's muzzle was a tight band around his cock, milking and suckling, its sucking pressure making his cock stretch even larger. It thinned around the base, where his muzzle wrapped tight around his shaft, only to swell larger and larger down his throat and in his chest, shaft deformed into a bloated, bulging swell, his cockhead immense and monstrous lodged inside the lion's chest.

Nao was mindlessly whimpering, what felt like seconds away from coming right inside the lion, when abruptly the lion pulled back, cock pulling from his mouth with a wet squelch, syrupy gel and pre splashing out across Nao's stomach. His hands pulled from the lion's shoulders, thick strings still webbing between them until the lion pulled back even further, Nao's leaking cockhead bursting from his mouth with a soggy explosion. His dick had grown enormous, stretchy and bloated. He hadn't noticed until it was out, but his cock was almost fully the length of his legs, the end of his shaft and cockhead swollen thick as his hips. Left alone, he could see it slowly twitching, its newly-squishy material redistributing itself into something more... normal. The lion didn't leave him alone for long enough for that to happen.

He tipped Nao back, his huge paw-hands wrapping around Nao's calves with room to spare. Nao's dick lolled forward to smack him in the face, the bloated-huge cockhead completely covering his face and softly squishing against his nose and lips, the heavy, pliant flesh smearing over the curve of his forehead, his flesh wet and silky. Nao gasped, breath wet and humid over his soaking skin, crackling out around the seams, his shuddered moan muffled by the mass of his cock.

He shook it to the side, the heavy pillar rolling slowly over his chest, inexorable as it hit the grassy ground over his shoulder, wet precome squirting out and coating one of his long ears. He reflexively lapped and slurped on his flushed, bloated cock, swallowing mouthfuls of wet gel slime clinging to the surface, face still half-covered by the curve of his cockhead, one eye pressed closed, smeared against the heavy weight.

The lion jostled him, wet air rushing across Nao's ass as he lifted Nao's balls up, hands and forearms shoving them up over his thighs. They rolled apart, one sagging down on either side of his thin waist, the glossy, porcelain pink flesh of his sac stretching easily.

As he sat back on his haunches, Nao got his first good glimpse of the lion's cock: something monstrous and animal, almost as big as Nao's stretched, oversized cock. His cockhead came to a sharp, angry point, but even the very tip was the size of Nao's palm, a crater-like hole at the tip flexing, wetly opening and closing as the lion drooled out pinkish slime, glossy and thick as it piled up across the now-exposed underside of his nuts, flopped heavily over his stomach. The lion's cock was an immense swell between his thighs, golden orange, fur in congealed ruffs and tangles. Dimly, through his flesh, Nao could see his balls themselves, fat and immense, orange-red and misshapen, curled like swollen beans, churning slowly as the lion's cock ticked upwards.

It was spiky, the ridge of his cockhead completely covered in backwards-facing spikes, like immense thorns, all fat and thick. Each fat pointed spine was the size of an average cock, tips tapered and blunted, in rings around the lion's cockhead. The man's dick just got thicker the further down it went, until at his hips it was the size of his hips, sheath stretched out impossibly wide, the golden gel-flesh of his sheath stretched wholly transparent. And even that wasn't the end of it; through his body Nao could see the inner root of his cock, some monstrous swell lodged inside him, cherry-red flesh opening into fat cords that wound in looping coils down into his sac, wrapping around the bloated swell of his balls.

Wet air blew over the backs of his thighs, held up in the air. The lion reached down, slimy claws digging into the flesh of his ass. Nao's cheeks parted easily, the new stretchiness of his body letting his asshole simply bow outward, parting open to reveal his inner flesh.

The lion hunched further, smearing the tip of his barbed cock up and down the furrow of Nao's asscrack, his huge tip keeping Nao's cheeks spread all by itself. He sprayed pre up the line of Nao's back, soaking into his matted fur until he was glossy, coated with globs of syrupy precome, a soaking river glugging down his crack, slurping into his open hole. The lion pushed forward, his squishy cocktip scraping down Nao's ass until it settled against the open ring of his asshole. Even the slightest fraction of the sharp tip was too large to push inside; it settled against the muscled ring, pulsing as the lion sprayed precome in a sloppy stream across Nao's ass.

Nao groaned, mouth hanging open as the lion pushed into him, the mammoth cock bulging and compressing as it ever-so-slowly sunk into his ass. Even with the squishy, deforming gel it still spread him impossibly wide, the comparatively narrow tip spreading wider and wider. Nao reflexively clenched down around it, then gasped as the lion's cock bulged inside him, cockhead thinning around his asshole, all the gel forced back or forward, the slight press of his cock inside him swelling up even larger.

The lion kept pushing forward, the bulge of displaced gel growing larger and larger down his shaft as he worked his cockhead inside, barbs popping into Nao's ass one by one, elastic and springy as they popped over the stretched furl of his asshole. The flesh of his stretched nuts shifted over his stomach as it slowly expanded, the fat head of the lion's cock alone already stretching Nao's body out, trim stomach bloated low, just above his hips. His cock surged up, propped by the length of the lion's dick inside him, sagging heavily against Nao's bulging stomach.

The lion's precome sloshed inside him, gurgling in his ass, and it was only seconds before the dizzy heat returned, his flesh feeling tense and feverish. Now, the second time, Nao could identify it for what it was, the heat of the... something soaking into him, stretching him out, this time directly from the lion's pre, instead of through the fruit. His asshole ached, muscle warping as it grew thicker, more flexible; it spasmed around the lion's shaft, forcing the solid core of his cock to compress, gel swelling out on either side, but it kept spasming, practically fluttering around the lion's cock, and the swell of his cockhead, lodged inside Nao's quivering ass, grew bigger and bigger, until he could feel every single spine lodged in the flesh of his ass, bloated and quivering.

The lion roared, echoing all through the forest. He surged forward, plunging feet of his bloated, swollen cock into Nao's ass in a wet, liquid slam. Nao's breath left him in a ragged wheeze, breath knocked out of him from the inside. The lion's cock speared into him, the bloat of his stomach suddenly an impossible swell, skin and fur clinging to the huge, hazily-defined pillar of his cock, dragging out across his stomach.

The lion groaned, hunching forward, and the ragged pillar of his cock plunged forward with him. His heavy barbs cannonaded through Nao's guts, smooth ridges as they sunk deeper into his guts. Nao groaned, squirming, as his stomach expanded in a rush. His skin flushed a rich pink as it stretched further, only to collapse back, white and pale, when the lion drew back.

His barbs scraped and caught all along the inner surface of Nao's ludicrously-stretched guts, becoming stiff rubbery claws dragging back over his sensitive flesh, and Nao writhed as they dragged furrows through his newly-stretchy body. Nao's cock slapped back down against his chest on the withdrawal, the impact a sharp burst of pleasure-pain event as it sprayed a volley of pre off into the bushes. Syrupy juices slobbered from Nao's ass, squelching around that massive shaft, a wet explosion spraying across Nao's upturned cheeks when the lion drew back as far as possible, cockhead lodged inside him; the whole flesh of his asshole bowing back as the barbs caught against the inner rim of his asshole.

The lion started thrusting, each one's sheer force slamming Nao into the ground. His asshole bowed into a gaping, hungry ring, heavy syrup drooling out of him as the lion churned up his insides, stomach bloating impossibly huge until it looked like Nao had just been speared through, the body-sized spread of the lion' cock simply wrapping around Nao's whole body, the syrup soaking into his guts letting him stretch easily around such an enormous thing.

The lion bottomed out inside him, bloated sheath smacking against his gaping asshole with a wet, slobbery smack. His cock was spewing precome with enough force to bubble Nao's thin, stretched flesh. The heavy floods of precome were visible from the outside, like new veins rippling down Nao's over-stretched stomach.

He kept himself buried inside Nao, hunching his hips, but only working the final few inches of his cock back and forth, jabbing his cock against the swell of stretched flesh over his stomach, the very base of his shaft rubbing back and forth of Nao's stretched, inflated prostate, milking out heavy, sluggish floods of precome, all sloshing up across his neck and shoulder.

Nao gasped wetly, reaching down to peel his heavy cheeks apart, letting the lion slam his cock down to the very base. The stubby barbs at the base of his cock plucked across the gaping, flushed ring of Nao's asshole, each withdrawal sending shuddering waves of prickling pleasure through his body. Each smacking thrust made him slosh, body so full of gummy, syrupy pre he was rounding out, stomach swelling, heavy torrents of liquid inside him crashing against his inner walls, soaking into his flesh.

The lion, too, was... dripping. His mane was plastered to his head and neck, as if it were sweat-soaked, but rivulets of burnished gold were streaking down over his shoulders and neck, pulsing like new veins. The rest of him, too: webs of streaky colors spread across his chest and arms, sections of color bleeding into one another as he kept rutting into Nao. Even his cock, lodged deep inside, was swelling, flexing, bending in strange ways. His barbs dragged all along the inner walls of his guts, but less and less, like they were being worn away.

The lion lurched forward, hips crashing against Nao's ass with a liquid smack, and then he kept pushing. His hips bulged, gel distending around Nao's ass. Spikes of the lion's dripping fur wetly squished against the backs of his thighs and stuck, leaving them glued together. The lion got more and more soggy, flesh stretching like thick taffy. He rocked back, hips and stomach bloating out as they remained attached to Nao's hips, all that fiery gold and yellow leeching across Nao's ass in wet streams, soaking into his skin.

His cock dragged backwards, out of Nao's guts, until only the melon-sized head was lodged against his hips, and the lion himself looked like something out of an animation smear, drawn out in rippling lines for a moment before he slammed back inside. Except... he canted his hips, cock at a different angle, and he thrust up, right against Nao's prostate and the root of his cock. Nao cried out, gasping, as his cock sprayed pre in a fountaining gasp, and then again as the lion started up a rapid thrust, slamming his cock harder and harder.

Nao shuddered at the impossible sensation, the lion's gel cock slamming into his bloated, squishy flesh and pushing through. Sheets of tissue, or gel, or simply thickened pre sluiced around the lion's cock as he thrust right up into Nao's towering cock. Each thrust made his cock plump out, wrapped impossibly tight and clenching around the lion's impossible flesh. Nao's shaft stretched thicker, flushing red; heavy, fat veins popped to the surface, only to recede as the lion withdrew.

Nao shuddered, writhing, hands dragging up to stroke their combined cock. When the lion thrust deep his shaft prickled under his fingertips, minute barbs pushing to the surface, flaring out from his cockhead like the petals of a flower, blooming and then wilting down to merge with his shaft in thrust after thrust. But with each thrust the lion slopped further into him. His hips -- their hips, half-overlapped now, were soaked in gel, gold and yellow mixing with Nao's pale white and purple streaks.

Nubby barbs remained around Nao's cockhead even when the lion drew back, the whole length a heavy, blushing pink. Nao reached up, shuddering fingers plucking at his heavy spines, and he let out a high, shuddering moan. His cockhead flared open and sprayed pre up in a fountaining gush, splashing down all across his face. He dragged his hands back and forth over the palm-sized length of his spines, fat and huge when the lion bottomed out. The very shape of his cockhead changed, sharp and sloped, only for it to shift back, distending and rippling under his spread hands. But as the lion worked his cock -- worked himself -- deeper inside, Nao became more and more leonine, the sharp tip, the fat spines, the dark red flush, all staining permanently across his cock.

Nao could feel his orgasm rise, dizzy heat all through their shared organ. The lion felt it too, eyes rolling in his head, mouth open and slavering, and even as Nao just moaned and whimpered through it, the lion roared. His jaw spread in a white snarl, fangs bared as he fell forward. His chest smacked rubbery and liquid all over Nao's body, immense ropes of golden gel smashing off the lion's body, wrapping in slimy cords over Nao's thin chest. They sunk into him, staining his fur in stripes, so hot they almost burned. His muscles ached in sympathy, his... fur, skin, gel-body.. thickening in minute pulses as the lion's gel soaked into him. They thickened, hot and feverish across his chest, the flex of his stomach suddenly a lot more powerful in some abstract way as he arched up against the lion's gummy body.

The lion's face opened in a snarl, or a kiss, stretched inhumanly wide, and Nao could only stare as he bit down on his face. Gummy teeth bit down uselessly across his scalp and neck, and suddenly he was immersed inside the syrupy gel the lion's whole body had become. Nao inhaled, gel seeping through his transformed flesh, the lion not so much dissolving as sinking inside him, staining his fur with yellow-gold patterns on top of his purple markings, making a complex and multicolored diagram across his head and shoulders.

Still pumping, even half merged together, the lion -- torso pushed inside Nao's body, stomach distended around his cock, balls smeared halfway inside Nao's hips, his legs and hips half-overlapped but still thrusting -- finally came. With their shared cock, Nao came too, in a mind-blowing rush, aware of nothing but the combined pulse of their four balls, thick internal cords bulging beneath his skin as they pumped their mixed loads up through their cock. Each tiny twitch of his cock, newly sharp and dripping, sent lightning bolts of pleasure up through his body, leaving prickling heat in its wake, cloudy and hot through his new gel substrate.

The gush of syrupy come the erupted from his cock wasn't so different from the gel already soaking into him all over already. He came buckets, vastly more than before, his new lion-cock flaring out, spikes distended, chunks of gel-jizz spurting out in a constant heavy flood, trailing down the new curves of his altered dick, dripping down across his stomach in a series of wet, liquid splats.

Slowly, through the pulsing fog of orgasm, Nao found himself rutting upwards, the muscles of his chest and stomach thickening under his skin, swelling with a dizzy rush into bloated slabs of leonine muscle. His pecs were too-large on his still-thin frame, a heavy shelf across his chest, but he found himself humping the air, dick a massive fucking pillar as he thrust uselessly up. The new muscles over his hips and stomach were tinged gold, flexing in tight, muscular contractions, a new power spreading inside him as the lion merged with him.

He dug his hands into the soggy, heaving sides of his shaft, squeaking and dragging across his transformed flesh. His cock pulsed, gel distending out in a fat bulge all the way up his shaft, and at the tip his cockslit parted and shot out a solid, gummy blast of jizz, one that splattered messily against the treetrunk behind him and clung there, a solid wet mass with thinner ooze dripping from it. Nao howled, jaw opening in a minute parody of the lion's, and his roar -- though much higher pitched -- brought the jungle to a standstill as he emptied his load in gushing splashes all across the treetrunk, the final dregs just splashing over his chest, gummy droplets exploding like water balloons when they hit, mucous gel soggily splashing all over him.

It was longer still before he could manage to get up. His body was... strange, heavier, his gel-flesh not-quite-translucent, like thick glass. His muscles, too, were bigger, immense things like the lion had, and awkward on his smaller frame. He was some kind of messed up chimera now, half rabbit, half-lion, patterning a mess of purple and gold, with streaky lines of yellow and red and white and crazed stripes all over.

The immense weight of his cock -- spiky and deep red, too big to even fit fully in his new, oversized sheath -- wasn't a burden anymore, with his newly-muscled legs, his hips and ass thick and curved, plump with new muscle. He stood and his body stretched in new ways, balls sagging almost to the ground, cock dripping pre constantly all over, the tip sharp and pointed, his slit a wide circle, reflexively flexing open to spit out stringy lines of pre.

Nao took a few staggering steps forward, heat rushing through his muscles, pounding in his head. He grinned, teeth sharper and larger, even if they were still fundamentally more rabbity than anything else. "Forget fruit", he thought, as he leapt off the path, running through the jungle with a new set of instincts, his heavy paws spread, leaving strange pawprints in the undergrowth. "I'm a carnivore now!"
