Jak has some problems staying entirely human when he gets intimate, but it turns out Sig might be into that kind of thing.


oh right i wrote this a few months back, but completely forgot about posting it here. i suppose it depends on if "temporary transformation into a demon" meets your definition of sufficiently furry.


Sig didn't even know how he got here. No, that was a lie: he knew exactly how it happened.

Jak was Krew's new gopher, a pretty little thing with wide eyes, lean muscles, and a swagger three sizes too big to fit his frame. The first time Sig saw him, he wanted to know what he'd look like, sprawled out and naked, Sig's cock in his ass. He looked like he'd be loud.

Even finding out Jak was some escaped experiment, pumped full of Dark Eco, didn't damp his enthusiasm -- which he found out in the middle of a firefight, Jak roaring like a wild animal as he turned pale and grew horns, before he ripped apart a dozen Metal Heads with his bare hands. Sig went home and jerked off thinking of those pale hands jerking his cock, those inky black eyes looking up at him while Jak sucked him. It'd been building for a while.

That evening Jak and his pet rat were at the Hip Hog, drinking. Sig almost felt sorry for them; he oughta tell them no one drank there. He was there after an outing for Krew, gone out into the mountains looking for relics, and he came back tired and still bleeding in places. Daxter was into his cups, warbling in a high-pitched whine that cut through the entire room, but Jak was just staring down at his drink, running his fingers over the rim. In the light, his eyes were dark, and his lips were flushed purple.

"What's got into you?" Sig said, leaning up against the bar, and Jak started, like he hadn't heard him approach.

Jak opened his mouth, preempted by Daxter focusing his bleary eyes on Sig. "Jak here got rejected!" he said, cheerful in his drunkenness. "Again!" Jak scowled at his drink.

"You can be... forceful," Sig said, smirking down, and Jak scowled at him while Daxter broke out in giggles.

"It wasn't even tall, dark, and scary!" Daxter giggled. "Broody here is a hit with everyone! It's the perfect bait. God, do you think I should change my image? Fuzzy... but dangerous!" Daxter tried to pose and nearly fell off the bar.

"He scored some underground guy, but he freaked out the second he saw his dick!" Daxter said the last part loud enough that it would've turned every head in the place, if there were any other heads in the place. Jak jolted up, cheeks pinking, and swatted at Daxter. "He's got a weird-- mm, hmmhm hrmm hmm" Daxter said, muffled when Jak slapped a hand over his mouth. Evidently Daxter licked his hand; Jak jerked back, wiping drool off his hand while Daxter spat. "Yeah, that's no picnic for me either; I know where those hands have been!"

Sig rolled his eyes. Still, it wasn't like he was ever gonna get a better opening: "What about your dick, cherry-boy?"

Jak started and turned towards him, real slow. His mouth was hanging open, lips parted fractionally. "Uh," he said, voice husky and low. "I don't-- you-- what?"

Sig leaned in. "I'm saying, if you're having trouble catching someone, I might be willing to take it in my own hands."

Jak still looked dumbstruck. Daxter looked back and forth between them, before hissing "Is Sig hitting on you?!" in what he probably thought was a whisper.

"We could go back to my place. You know what they say, I'll show you mine if..."

"Sig, I gotta say, this is totally changing how I look about you, man," Daxter said, just staring. Jak was flushing, purple-red. "But honestly, guys've said that before, and--" he cut off when Sig reached out for him, yelping backwards.

"I'd rather hear from you than your talking rat."

"Hey!" Daxter yelled, but Jak just slid off his seat, eyes still a little wide.

"Yeah, sure." He turned back to Daxter. "You can-- stay here, right?"

"You better tell me everything!!" Daxter yelled on their way out.

Outside was cold, sun just below the wall, lights coming on all across the port.

"My place's at the edge of the port, that way," Sig said, directing them, and Jak followed behind him. "I meant it though; you wouldn't believe some of the guys I've been with. Dated a Lurker for a while; he was pretty wild." Jak stared. Sig grit out: "You wanna talk about it?", trying not to sound too grudging about it.

"Uh," Jak said again, and he was walking funny, hands brushing against the front of his pants, tugging them flat.

"Remember that time I got near clawed-open by Metal Heads on the beach?" Jak nodded, jerkily. "And I had to take off my armor, and you spent the whole time just staring at my chest?"

Jak flushed again, darker. "Didn't realize you noticed."

Sig hummed. "I was thinking what you'd look like on your knees, sucking my dick." Jak nearly tripped over his own feet. Sig just shrugged, slowly rolling his shoulders. "If you're into that kind of thing, you know."

Jak was tented in his pants, cock a low bulge, stiffening further under Sig's gaze. "Uh," Jak said again. "After the, uh --" and he made a gesture, something Sig figured was short for 'the years of torture and scientific experimentation', "-- I can't keep control if I, uh..."

"You saying you gonna go Dark Jak when you get into it?"

"No! I mean... sometimes, yeah."

Sig laughed. "That must be a show-stopper."

"Yeah," Jak said, more than a little bitter. "Not that I've even gotten that far with anyone."

Sig kept walking, but he whipped his head over to look at Jak. "You saying you're really cherry, cherry-boy?"

"Yeah...?" he said, like he was afraid that was bad.

Sig looked around, at the near-deserted causeway, and pushed Jak up against a building wall. "Don't know what I did to get so lucky," he said, hands wrapping around Jak's shoulder and side, pressing their bodies together. Yeah, Jak was hard; their cocks dragged against each other, just swells of hardness under their clothes. Jak's mouth opened, a shaking whine ripping from his throat as he pressed himself to Sig's body, hands digging under his shirt. His hands were cold, pressing against his stomach, calloused fingertips rubbing between the cuts of his abs.

Sig bent down, pinning Jak against the wall, dragging his lips over the base of Jak's ear. They were close enough he could feel every little tremor that went through Jak's body. "Gonna give you a lot more than a touch," he said, wrapping his hand around Jak's, dragging it down to his crotch, letting Jak curl his fingers around the bulge of his cock. Jak just kept staring at him, eyes wide, his lips parted, and Sig didn't feel like holding out any longer. "Gonna kiss you, kid," he said, lips already brushing against Jak's, and the kid let out another shuddering whine and jerked forward, lips parted, kissing him inexpertly but enthusiastically. He kept drawing back to drag in shuddering breaths, desperate little gasps popping up his throat. Kid was desperate, that much was obvious.

Sig broke away before Jak came in his pants, and Jak followed the movement, leaning forward until he tipped over against Sig's chest. "Almost there," he whispered. "You really are a needy little thing, huh?"

They staggered through the narrow door of Sig's building, and then up three flights to the narrow apartment at the top of the building, practically hanging out over the city wall.

Jak's hands were feverish, pawing under Sig's shirt, his head buried against his neck, mouth open as he sucked and bit on his neck. Quick learner.

"Let me-- get out of this--" Sig said, between almost bruising kisses, tugging at the clasps of his armor, helmet scraping through his stubbly hair, one pauldron all cockeyed. Jak just wouldn't pull back long enough for him to get anything off, his hands tugging and groping all across his chest and arms, down to cup his cock. "Fuck, if I'd known about this, I would've worn something easier to get off."

Sig finally ripped his armor off, letting it drop with a crash, and Jak just looked at him and groaned, like he was gonna climb him like a tree. "Not so quick, cherry-boy," he said, wrapping two fingers under the ring strapped on Jak's tunic and pulling him over to the bed, just a mattress on some boxsprings in the corner of the room. Jak bounced when he hit it. "We're gonna do this right. Strip." Sig unfastened his belt, tugging the heavy shroud wrapped around his thighs, unzipping his pants beneath. It took him a minute to realize Jak wasn't moving. He looked up at Jak, who was nervously looking away. "What's up?"

Jak huffed, before he clenched his jaw, resolutely pulling off his clothes piece by piece. The angry stripping was pretty hot, even if he probably didn't mean it that way. He finally tossed his undershirt to the side, sitting there on Sig's bed in just his pants, looking oddly vulnerable for someone who could cause so much havok.

And, well, Sig could kinda see why he'd been so worried. In retrospect -- back before, he'd seen Jak's shirtsleeves ride up, or his collar ride down, and caught a trace of black lines, but that kind of thing was hardly worth remarking on; half the city had guard tattoos or prisoner tattoos. And, yeah, he could see the spidery script of prisoner lines across his back, but that wasn't the issue.

Veins bulged in spidery lines across his skin, every one of them a pale purple under his skin: in a solid squiggle from his shoulder to the center of his chest; in branching lines across his biceps and sides; with two in asymmetrical lines down his stomach, vanishing under the hem of his pants. They were spread across his skin, branching and clustering, and pencil-thick, like he was some kind of extreme bodybuilder. Jak was lean, muscles tight and defined, but he was nowhere near as muscled as he'd need to be to get this kind of... whatever.

His nipples, too, were a dusky purple -- Sig'd noticed, before, that Jak's lips and tongue were purplish, but this put it in context, with his flesh all stained from dark eco.

Compared to that, the scars he'd been expecting -- ragged gashes on his stomach and back -- were unobtrusive, just crests of pale flesh.

"You got kicked out of bed for that?" Sig snorted. "Stop getting with scrawny little activists, doughboy, and you wouldn't have this problem." Sig tugged on his belt, pulling his pants tight around the bulge of his cock, and Jak's gaze dropped down, smoldering. "I thought I told you to strip."

Jak tugged on his pants, dragging them down to mid-thigh -- he was wearing ragged boxer-briefs underneath, flat grey, with holes along the seams, and they were bulging like he'd stuffed his pet rat down there. Mostly Jak stared as Sig shucked his pants. His cock swung out, heavy enough to point almost straight ahead, and Jak's hands stilled, leaning in like he was caught in a gravitational pull, lips parted. And hell, like Sig was gonna deny the kid that.

He took the two steps forward, cock slinging to the side with each one, until it was right in front of Jak's face. Jak's breath wrapped around it, hot and humid, and his lips opened wider, tongue flicking out to wet them. Sig's cock twitched.

Sig settled, legs planted on either side of Jak's chest. "Well, cherryboy, I think you know what to do with this." He wrapped a hand over Jak's head, fingers sinking into his silky hair, and guided him forward. Jak's mouth made contact, pressure slick and fleeting, and he opened wide before slipping his lips over Sig's cock. His tongue slid up, inquisitively dragging along the underside of Sig's cockhead, and he groaned, tugging him fractionally forward. "You're a natural."

Jak whimpered around Sig's cock, moaning and slurping as he drooled down his shaft. He kept trying to take it all in, almost gagging each time, until Sig settled a hand in the crook of his neck, keeping him back, since Jak sure wasn't gonna stop trying. The noises he made were unreal, sharp high whines, muffled around Sig's cock.

The rapid flutter of his heart was visible in his veins, pulsing with each beat. The tent of his cock in his ragged underwear was completely obscene, gigantic, and Sig was almost curious enough to push Jak off -- wondering about exactly where those veins were running down to. Almost, though. He combed his fingers through Jak's hair, petting him as he slobbered and sucked on his cock -- inexpert, no clue what he was doing aside from being a hot, wet hole, but so eager. Sig wasn't gonna come from this, but he figured Jak was panting for it, might as well let him get a taste.

"C'mon," he said, pulling back until Jak almost slid off the bed in his hunger to keep Sig's cock in his mouth. Sig sat on the edge, legs wide, and Jak just sunk down onto his knees, lips flushed, eyes hooded -- just staring straight at Sig's pipe of a cock, twitching as his breath streamed over the slobbery length. His mouth opened, lips kissing Sig's cockhead again, and this time when he tried to deep-throat it Sig pulled him back.

"Like this," Sig said, fingers wrapped in Jak's hair as he pulled him back, until he only had Sig's cockhead in his mouth. He guided Jak, lips dragging over the ridge of his cockhead, slack but pursing as the thick wedge popped over his lips. "Back and forth like that, kid -- yeah, you're a natural."

Sig sighed, head tipped back, eyes closed. "Use your tongue, yeah, lick the tip -- good boy." Jak's whole body trembled, eyes fluttering shut as he moaned around Sig's cock, and Sig smirked to himself. Jak'd gotten on all fours, hands planted on the floor between his knees, and he was rocking forward, grinding his dick against his forearms. Sig always had thought Jak seemed like the kind of guy who liked getting ordered around. "Like that, huh? Bet you've been panting for it."

Jak was loud, slurps and pops filling the room as he slobbered over Sig's dick, and underneath it he was making these soft little whimpers, pulling off to gasp wetly, throat thick with spit. He still wasn't the best, but he was a damn quick learner. He bobbed between Sig's thighs, nursing his cockhead, his spit drooling down Sig's cock and matting into his pubes. Sig set the pace, tugging him faster, grinning at the resistance when he pushed Jak back, like it was all the kid wanted to try and choke himself on someone's cock.

It was a while before Sig felt the pleasure start to peak, Jak's little whimpers doing just as much as his sloppy, eager mouth. He thought about it, dumping his load in Jak's mouth, but in the end -- "C'mon, kid, get up here," he said, pulling Jak off his cock with a wet slurp. Jak's chin was dripping with spit, his eyes dazed, and it took a second for him to focus. "Wanna get you off, first."

"Uh--" Jak said, voice wrecked, clotted and catching. He sat back, hands still covering his dick, except it wasn't like he could actually hide what he was packing. His underwear was_soaked_, honestly looking like he'd pissed himself, fabric soaking wet and stuck to his thighs, except the fluid smeared over his thighs and sheened on his forearms was thick and glossy, clear tinged glowing purple.

"Don't worry about it," Sig said, and pulled him up, except as Jak flopped onto the bed he was starting to think maybe he should be worrying about it. There were thick runnels of pre across Jak's inner thighs, some hanging down in strands. They saturated Sig's sheets, soaking the off-white fabric a dusky purple. The kid's boxer-briefs were threadbare, and no shit, if that was the kind of thing he had inside them -- the arch of his cock was outlined through them, about ready to rip through, pulsing against the sodden fabric with every heartbeat. And it smelled: not bad, just strong; it had a chemical tang, the sweat and sex just an undertone to the rotten-metal stench, with an undertone of the sour-acid tang of dark eco.

For all his eagerness, Jak seemed ill at-ease lying there, limbs sprawled out but tense, gaze flitting from Sig's face to the swell of his cock.

"Don't worry about it," Sig repeated, pulling the waistband of Jak's underwear. They peeled off him, the inside scummy with slime, and when Jak's cock flopped out it hit his stomach with a heavy, meaty smack, spattering droplets of precome up over his chest.

To call it monstrous would be putting it gently. The thing was like a cudgel, a weight attached to his crotch, too-big to fit his frame and then some. The dark veins over his skin swelled even closer to the surface, the pale-purple tinge becoming darker and richer, bright against his skin. His balls were lopsided, so big he could see their kidney-bean curve. They strained against the gnarled, vein-covered flesh of Jak's sac, and they were churning fast, flesh tensing and relaxing across his balls, making them constantly shift up and down like a living thing.

If he'd thought it smelled before, there were practically fumes coming off it now, some strange alien musk that overpowered even the pollution reek of the air outside. It honestly -- and there was no way Sig would ever say this out loud -- reminded him of a Yakow udder: thick milk veins across Jak's stomach and thighs, cutting over his hips to wrap around his monstrous shaft, trailing up his cock like it was some obscene teat, oozing some new milk.

He was uncut, too. And whatever transformation -- Sig assumed this was because of Jak's eco treatments, not that he was just inhumanly hung in addition -- had grown his cock hadn't worked so well on his foreskin; his cockhead peeked out from his drawn-tight foreskin, a little circle of purple skin almost drowned under waves of precome constantly oozing out. Slime dripped out over Jak's chest, slowly spreading along the cut of his muscles.

The thing was too heavy even to stand upright; its sheer weight pinned it to Jak's stomach.

Sig let out a low whistle. "I gotta say, doughboy, I could name a lotta guys who'd trade dicks with you in a heartbeat, if y'think that's such a curse." He knelt closer, hands curling over Jak's thin hips. One thumb dug into the thick flesh of his shaft; Jak's skin was burning hot and damp with pre. Jak let out a little whimper, hips jerking, and his cock lolled to the side, vastly more than a handful.

Sig leaned in, breathing through his mouth to avoid the chemical reek, and dragged his tongue along the underside, all sloppy and wet. Jak keened, hips jerking up, smearing his shaft over Sig's cheek, but he'd already jerked back, nose scrunching, sputtering. "You taste like battery acid."

Jak flushed, and not in a good way. "Sorry."

"Nah, just gotta..." Sig stuck two fingers in his mouth, drooling all over them, and pulled them out with a pop, grinning at Jak's wide expression. He slid them through the mess of Jak's cockhead, fingertips skirting his straining foreskin, and slowly sunk them inside. Jak keened again, mouth open wide, sharp inhuman noises coming out. Sig worked around his cockhead, sloppy fingers squelching through the mess of precome trapped inside. His fingers dragged against the thick cord of flesh webbed between his cockhead and foreskin, and Jak just whimpered as Sig ground back and forth against it, hips jerking upward from some animal impulse.

Like before: Jak'd wrapped his hands against the lip of the mattress, fingers white-knuckled as he gripped down, just rocking his hips against Sig's hand, the near fist-sized swell of his cockhead fitting nicely against Sig's palm.

"Need someone to help you out, don't ya? Don't know what to do with all this." He stroked him off, other hand wrapping around most of his shaft, fingers not even close to meeting. The movement, stroking him, was near frictionless, slick with Jak's precome in dripping sheets all over. "Don't worry," Sig said, leaning in. "I can take care of you easy."

Jak just threw his head back, back arched like a bow, hips jerking up and up as Sig jacked him off, pumping the length of his dick like he was cocking a gun, two fingers shoved inside his foreskin, with huge streaks of precome squirting out, drenching his hands.

And Jak was loud, whimpers and gasps every time Sig did anything, and these sharp, almost animal groans, sucking breaths, a cacophony that did nothing to drown out the wet squelch-splatter of his cock spurting slimy precome all over his stomach and chest, streaking over the backs of Sig's hands. The slime was feverishly hot, thick and near-translucent, tinged purple. There was so much of it, droplets splattering all over with each pump, spurting like a running faucet.

Jak moaned again, something that might have been words, too broken to understand, but his hips jerked sharper, slapping the curve of Sig's hand against his crotch. His hip bones were sharply defined under his skin, ribs fluttering into existence as his stomach hollowed, replaced in an instant by the flex of his muscles as he arched up, thrusting his cock back and forth through Sig's hand. He groaned again, something that was definitely supposed to be "Sig," and then he came all over the place.

His cock thundered in Sig's hand, jerking to the side, and he erupted like a gunshot, come bulging his foreskin and then swamping out all over Sig's hand, still hard enough to web across the back, smearing over his knuckles. Sig jerked down, more on accident than anything, pulling Jak's foreskin back just enough, and the next shot erupted up, splattering the wall behind the bed with a finger-thick line of glowing purple-white jizz. Jak just writhed, hips jerking.

Dark eco crackled around him, zinging across Sig's skin before earthing itself back inside Jak. Even as Jak trembled and whined, coming his brains out, his skin went pallid white, claws puncturing the mattress, horns erupting from his skull with a sharp crack. He whined, mouth open, eyes closed, back arching up until he was almost propped up on his shoulders, and when he opened his eyes again they were a flat, inky black.

Sig was a little impressed he kept his hands on Jak's cock. Even aside from him turning into a monster, it was just beautiful to watch the kid come undone, fangs clacking in his mouth as he whimpered and shuddered, newly-pallid cock still coming, spitting out thick, chunky lines of jizz across his stomach and chest, over his shoulder, a near-solid mess over the mattress and up the wall.

It felt like minutes before Jak finally stopped, cock going... not limp, exactly, but half-hard, heavy and spongy in Sig's hand. He let go, fingers pulling out from Jak's foreskin with an obscene burble, and let it drop against his stomach with a splat.

The flat black eyes were really creepy: Sig couldn't tell if Jak was actually looking at him, and the mouth full of dagger-like fangs was... strange. He'd seen Jak like this before, but that was out of the corner of his eye, busy trying to stay alive. Not having a monster spread out naked in his bed, chest heaving from blowing his load.

"You uh, not gonna flip out and try to kill me, huh?" Sig said, curling his hands in pale imitation of Jak's scything claws.

Jak blinked, slow; there was a low growl coming from his throat. But he tossed his head to the side. "Nah," he said, or that was... what it sounded like, lower and guttural, like he had metal shards grinding in his throat.

"You gonna be like that for a while?"

Jak nodded, slow and lazy, black eyes not-quite staring at Sig, and something clicked in Sig's head: instead of seeing Jak like some uncanny predator, ready to pounce, he was just some guy who'd just came his brains out, hazy in the afterglow, eyes not quite tracking again yet.

Sig looked down to the pale slope of Jak's skin, all pallid white, streaked with purple veins and now smeared thick with jizz. His muscles were a little larger, their weight more visible across Jak's stomach as he caught his breath, but they didn't make his cock look any less absurdly huge. Sig trailed his fingers down Jak's thigh, under his balls.

"You mind if I...?" he said, fingers sliding against Jak's asshole, his other hand pumping his cock back to full hardness. He wasn't gonna lie, staring at Dark Jak in his bed, he might've gone a little soft.

"Yeah." Jak's growl was a little more like a sigh, this time. He spread his legs, hitching up so Sig had better access, hooking his thighs over Sig's knees. It was a little surreal to see, the little wiggle of his hips just like any of the twinks he'd fucked, except here it was coming from some demon-looking monster, someone Sig'd seen rip a Metal Head in half with his bare claws. Claws that were currently digging into his mattress, audibly tearing the material as Sig slid his fingers down the crack of Jak's ass, to his puckered asshole.

Against the ghoulish white of Jak's skin, his asshole was a dusky purple, dark between his cheeks. Sig's fingers slid right in. Partly it was the come -- Jak's jizz was splattered all over his stomach, smearing his pubes to his stomach, dripping down his inner thighs, and Sig just smeared it up, globs catching on his fingertips as he pushed inside Jak's ass. But Jak opened, the ring of his ass spreading effortlessly, the muscle stretching like thick rubber. Sig slid his thumb in alongside, three fingers slipping back and forth over the entrance to his ass, and even when he spread them Jak just opened more, the muscle trembling as it opened, slow but easy.

Jak made completely inhuman noises, sounds Sig wouldn't have thought even animals could make: yowling through his fangs when Sig probed inside him; hissing and spitting. Like he hadn't just come a cup of fluid all up the wall, his cock twitched, too heavy to do anything but drag up his stomach as he got hard. He was already drooling fresh pre, tinged darker, dribbling out in messy streams all over his stomach.

Sig snorted, grinning down into Jak's black eyes. "Pent up, huh? First time really getting off." He gave Jak's cock a lazy pump, slime drooling from his foreskin in a ropy line. He jabbed sharper into Jak's ass, earning a feral growl, fangs audibly clattering against each other as the buzzsaw noise in his chest got louder. "I bet you--" he started, trailing off when his fingers dug right into Jak's prostate. Jak groaned, like broken gears, and his cock spat a thick, dark line of precome up his stomach.

For Sig, it was more that Jak was swollen. Most guys, yeah, the prostate was down there, through the wall of their ass, and he'd been with enough guys to know his way around an ass. But this he could feel, a bloated swell of flesh bulging out against the wall of his ass, a fist-sized bulge of spongy tissue. He dug in, fingers dimpling the swell, and Jak growled, thrashing side-to-side as his cock spat out dark lines of slime. It gurgled under Sig's finger, half-felt, as he withdrew.

Sig swallowed, mouth dry. "Really pent up there, huh cherry?" It was almost instinctive to push back in, two fingers pressing against the swell and digging in sharply. Jak thrashed, horns scraping twin lines down the wall, claws scraping through his increasingly-ruined mattress. Dark slime oozed out from Jak's foreskin, more when Sig pressed harder; his bloated prostate squelched and gurgled as he forced his fingers in, milking strange slime out of him.

It was almost accidental: Jak's ass opened up so easy, Sig found himself four fingers in, fingertips digging into the pulpy, swollen flesh inside him, and it was easy to just... push a little more. Jak's ass opened around the crest of his knuckles like it was just no thing. Jak hissed, horns tearing another chunk of drywall when he thrashed back. The hollow of his throat was shining with sweat. Sig made a fist, thumb curling inside, and with no effort at all he had his entire hand shoved up Jak's ass. The purple flesh of his asshole was banded around his wrist, heavy and stretchy, clenching and rippling to match the tremors running down his body.

The span of Sig's fingers just barely matched the swell of Jak's inflamed prostate. The slightest pressure milked dark eco ooze from his cock, cords of it oozing from his foreskin, the whole thing looking bloated and swollen, too-huge on the end of his cock. Sig had a hand free: he reached up, wrapped his hand around Jak's cockhead, and squeezed. Wet cracks filled the room as he milked out the inside of Jak's foreskin, sending black ooze drooling out between his fingers. Jak whined -- Jak was doing nothing but whining, sharp and high like a broken engine, and it gained pitch and volume as Sig pressed down harder.

"Gonna milk you like a Yakow, kid," Sig said, and hell, maybe he would say it to Jak's face. "Hope you're ready." He bore down against Jak's inflated prostate, his knuckles digging in, mashing the swell flat in a slow, inexorable press. Jak thrashed, his entire body shaking.

Thick purple slime spurted from his dick, splattering in dark lines across his chest, and the harder Sig pushed down the more came out, drawing back to rock forward again, punch-fucking Jak's swollen prostate. The amount of slime easily matched his entire orgasm -- eco ooze running down the lines of his muscles, soaking into Sig's sheets, all purple-black and glowing.

Sig tugged Jak's dick, base to tip, each time milking out a huge, slobbering gush of slime, squirting over his foreskin and drooling down Sig's fingers. Wet cracks turned into gurgling squelches as he kept it up, until Jak was whimpering and thrusting into his loose fist. For all the slime, it didn't seem like Jak came; he was still rock hard and oozing, just... oozing a muddied purple slime, now, all but crackling with eco.

"Sig, please," he said, voice cracking three times, and when Sig looked up Jak had tears in his eyes, solid black ichor oozing from his solid black eyes. "Fuck me!" he all but roared.

Sig laughed, rocking forward fractionally, sending his cock dragging over Jak's cheek. He pulled his hand out with a slurp, guiding his dick in with the same motion, and then he was hilted in Jak's ass, balls grinding against the curve of Jak's cheeks. He groaned, the muscles of Jak's ass practically milking him, all clench and heat, rippling to pull him deeper. He dug his hands into Jak's hips, gripping hard as he jerked back and then forward, slamming his cock against his still-swollen prostate -- wasn't gonna be any problem telling when he hit it, here.

Jak thrashed, fucking himself into each thrust. Sig hammered him into the mattress, ruined sheets and padding tearing apart under his claws. Jak made inhuman noises: wild animal howls, chainsaw snarls, the kind of thing that probably shoulda freaked Sig out. He just slammed in harder, faster, fucking into the sizzling heat of Jak's ass, his own groans drowned out under Jak's yowling. Every single thrust forced a purple slug of slime from Jak's dick, splattering over his skin, again and again until his stomach was saturated, soaking in eco slime.

Jak was just whining, high and sharp, hands making abortive movements to his dick -- like he wanted to get off but didn't want to chance it, with the razor sharp claws. His mouth was open and drooling, cheeks stained with black tears.

If there was one thing Sig was good at, it was fucking, and he sure as hell wasn't gonna disappoint. He felt Jak's body screw up, tension ratcheting up his spine as he got closer and closer to coming, until he was sobbing loud, voice screeching high before petering out in a desperate gasp, over and over. His asshole convulsed around Sig's dick. Sig fucked him right through it, over the edge of the cliff, and Jak went tense -- all the muscles of his stomach standing out in sharp relief, veins pulsing wider -- before he came again, keening. His foreskin was wrapped tight, dragged halfway down the purple-black flesh of his cockhead, and it was bulging around it. His cockslit was already spread open, fat enough on his monstrous cock Sig could've stuck a finger in there, no problem, but it yawned wider, bulging until it looked like a tiny mouth, lips spread. Shining, glossy lines of dark eco erupted from his cock, pure purple-black and crackling, hosing out his cock like it was an eco pump. It was heavy, arcing down sharply to splatter over Jak's shoulders, pooling in the hollow of his neck, webbing over his chin, shining across his bared teeth; just coating him all over in a messy slurry of eco jizz.

It was the hottest goddamn thing Sig'd ever seen. He groaned too, low, and with a whole lot less fanfare came in Jak's ass, still pounding him through his orgasm. His hands dug sharp into Jak's hips, rattling his entire body as he slammed in, spurting inside him. His whole load was probably as much as one of Jak's shots, but hell, he didn't have a complex about it; it was good enough to see Jak sprawled, dripping with his own load, pallid skin coated in a purplish slurry, his cock recoiling against his chest with each spurt of dark eco, splattered all over his face, dripping from the tips of his horns. Jak was lax under him as he finished, rolling thrusts slowing as he spent himself, finally dragging his cock from his hole with a pop, a single smear of his own jizz bubbling out after.

There was a miasma of dark eco over Jak, visible fumes raising from the glossy lines over his skin, the kind of shit that'd call for industrial containment in any other situation. But Jak just skimmed the backs of his fingers through the mess, eco crackling, and it soaked right into him: sucked right back into his body through his skin, leaving behind a near-solid gel, translucent and gummy. Neat trick, if you could do it.

Sig collapsed next to him on the bed, mattress sagging under him where Jak'd ripped out half the padding. "You can stay the night if you want," he said into Jak's ear, still pale, "but you'll wanna shower first, and you gotta help flip the mattress."
