Junkyard Dog Written by Leo_TodriusCommissioned by Draegon1993

If the old adage that one man's trash was another man's treasure was true, then one man's junkyard could be another man's paradise. The Fallow Flats junkyard sat at the edge of downtown beneath a sky painted orange and purple by light pollution. The soil beneath the junk was a rich reddish brown from all the rust. The main complex was a wide, flat structure with eight rooms and a slanted black corrugated metal roof; There were stacks of gutted cars, piles of rubbish, countless bins of odds and ends, and a fence that had been covered in graffiti so many times that no one could guess its original color.

Standing on the other side of the fence, Jake felt like testing his luck. It was two a.m. on a school night, but Jake hadn't been to school in almost a year. His blond hair was slicked back and his chin was covered with invisible peach fuzz, his desperate attempt to cultivate anything. Silver rings hung from his ear lobes, and he wore a black jacket with a grey hood, black jeans and a red t-shirt underneath. His blue eyes calculated the height of the wall, the give of the chain link base and the plastic slats woven in-between the links before he took a few steps and jumped.

His hand came up to catch what was undoubtedly some variation of razor wire, but rather than cutting into flesh, the wire hit the metal panel on the palm of his glove. Jake grasped tighter and held on, grabbed with his other gloved hand, and hoisted himself up and over. He landed in the rusty red dirt on the other side. Almost at once, he could smell a difference in the air. It was acrid with the scent of iron and sulphur, the scent of decomposed plastic and rubbers. He advanced slowly, carefully, keeping his eyes peeled for motion detectors or cameras. He had opted not to go for a disguise, so winding up on camera wasn't one of his hopes.

The thief turned the corner, his fingers drumming the leg of his pants. He thought about how much money he'd be able to get if he pawned what he found. It was amazing what people were willing to part with, as well as buy in the grand scheme of things. Jake looked closer at some of the stacked cars, spotting nothing close to the radio or CD players in any of them. Disgruntled, he turned a corner and nearly tripped over a chain.

Jake muttered under his breath, looking down at the thick links in the chain - and then saw them move. Jake's eyes widened slowly as he followed the chain one way and saw where it was mounted to a heavy duty D-ring on the side of the junkyard building with bolts, and then he followed the chain out the other way almost twenty five feet to a very large, very muscular, short hair Doberman with black and reddish-caramel colored fur.

The Doberman met eyes with the human. Jake gave a nervous grin, a squeak, and then he turned and broke into a run. The dog let out a resounding bark, paws hitting the dirt, kicking it up. Jake broke into a run, heading back the way he had come at top speed. He found the ground slick under his feet, his heart pounding, his eyes darting around. The fence seemed so much further away than it had moments before. The dog advanced faster, Jake sprinted for his life before he lunged.

The blond youth sprung up from the ground, a hand latching onto the sharp wire at the top of the fence, but something also snapped onto his pant leg. The Doberman growled, frothing at the mouth with rage. He snapped his head back and forth, yanking Jake's leg around like a rag doll. Jake yelped and tried to get up, pulling himself higher. The dog growled more, angered that it was losing its prisoner, that it was failing in its duty as guard dog. The Doberman's eyes shifted from honey to brown and then red. Its fangs grew longer and sharper, another set puncturing the black pants that Jake was wearing. Its ears took on sharper tips and more sinister curves, and its rumbled eyebrow shifted and contorted before horns erupted from the flesh, pushing back.

Jake heard pops and snaps, then a strange crackling. He looked back down despite his better judgment to see a ring of fire erupted around the guard dog's collar, consuming the leather but remaining bound by the metal. The dog's horns emerged, a rich ivory color like its huge, dripping fangs. Red eyes peered up in rage before the Doberman's maw opened wide and it clamped down again, this time latching into Jake's leg. The thief cursed out, accidentally letting go, falling to the ground as the fangs punctured his leg. He yelped and whimpered, sobbing as blood welled out of the wound. The guard dog had caught its prey. It was time to dispose of it properly.

The Doberman growled, clamping down on the bite of leg it had, waddling backwards. Jake screamed out, his hand clutching at the dirt, digging into it as he was dragged back into the junkyard. A trail of his flailing, waggling arms was left in the rich rusty red dirt as he was tugged back around the corner and out of sight. In moments the junkyard fell quiet once more, bathed in the eerie glow of the nighttime city lights.

****

Jake's screams seemed hoarse and hollow as he was dragged through the junkyard, catching his right arm on a stack of old broken appliances, his left leg grazing the fender of an old Cadillac. He winced and moaned, feeling the teeth in his leg, the searing hot saliva, the pain blossoming through his body before he was suddenly and unceremoniously released. Jake rolled into a heap, a cloud of rusty dust kicking up into the air. He panted hard, coughing, moaning, groaning. His neck ached. Hell, his whole body ached. He slowly pushed himself up into a sitting position, only to come face to muzzle with the guard dog. The demonic Doberman growled, thick sticky saliva slowly leaking from its yellowed fangs. Its red eyes gleamed with heat and its fiery collar blazed with otherworldly magic.

"I... I'm so sorry. I didn't... I mean, I did, but I don't want to steal now... I am so sorry. Just let me go please... Please?" Jake begged, "Uh, good doggy?" he whispered. The Doberman took a step forward, then another before its muzzle parted. Its tongue came out and it left a sticky, slimy trail of saliva up from Jake's throat to his fuzzy chin to his lips before the tongue pushed in.

Jake tried to resist, but the dog pushed forward, forcing his lips apart, and soon his mouth started to tingle. Jake shivered in surprise as the pain died away from his leg wound. His nipples hardened, his cock stiffened, and soon he opened his mouth wider. The dog growled and pushed its tongue in more before a clawed paw began to grope and work at the lap of Jake's pants. The first few efforts were in vain until he got it to start digging in, tugging through the fabric, making it thread bare before it split open.

"Oh please, what... what?" Jake panted, mouth full of doggy tongue before the Doberman lowered its haunches and Jake felt something hot, wet and slick slide into his pants. Why hadn't he worn underwear? Jake moaned, feeling the messy, slimy dog dick sliding across his own shaft. The demon dog started to hump, sliding back and forth as its curved, pointed, pepper shaped dick only got bigger and bigger and bigger, rivaling Jake's in length, then surpassing it.

Jake broke the kiss, gagging and coughing up the doggie drool before the demon dog licked his chin again and again and again before it moved to lick and slurp at his neck and shoulder, a clawed paw sliding up his shirt. Jake was pinned down, grunting as the beast humped him faster and harder. He shuddered, his leg tingling where the bite marks closed up. The demon dog growled louder and louder before Jake suddenly felt something hot and wet spreading across his lap as thick, hot demon dog cum poured over his cock, soaking his bush and balls, running down between his legs and across his taint.

The dog thrust several times, churning his seed on the thief's lap before he pulled back, popping out of Jake's pants. Jake gasped, wondering if it was over, if he'd really had the worst of it, but then he felt a swift swipe of movement, then cool air hitting his taint. The demon dog thrust again, this time at a different target. Jake yelped as his ass was hiked up, the cheeks penetrated, and that hot, slick, huge doggie dick pushed into his pucker.

Jake's back arched in response as he gasped out loud. He moaned hard in surprise, and then his eyes widened sharply. He felt a tickle around his neck, a tickle that grew into a tingle, then a sting before a flaming collar of fire erupted around his neck. A thick black metal ring appeared in the fiery collar at his throat before another link formed, then another and another and another, snaking out, dropping down to the ground before slithering and slipping down until it latched onto the long chain the demon dog was on.

Suddenly the pleasure filling Jake's ass magnified a dozen times over. His ass was actually moving with the cock invading it, pulling at it, tugging it, drawing it in deeper. Jake started to drool, his own saliva pouring over his lips as he actually rolled back, spread his legs wider, and let the demon Doberman go to town. The dog growled happily, thrusting faster, harder, deeper. Jake moaned, eyes squeezing shut, fingers digging into the rusty dust as he let himself get bred.

Jake reached down into the wet torn hole in his jeans and fished out his own cock, wrapping his fingers around it, stroking it up and down, feeling the thick viscous cum covering it. He worked it into his foreskin, even into his slit, using it as lube as he jerked his hips up and down, masturbating as he was fucked in the ass. The demon dog was enjoying himself.

As the human's moans grew more desperate, so too did the guard dog's grunts. The thrusts became ragged, uneven, messy, and then sticky. Jake was getting yanked around by the thrusts. At first he was confused, but then he realized that the guard dog couldn't get his fat cock back out... especially as he realized that the dog's dick had swelled at the base, growing into a thick, juicy knot.

Sensing he had locked in his mate, the guard dog tipped his head back, closed its red eyes and let out a resounding howl that echoed through the city itself all the way to the world beyond. It came with a huge flood, the thick seed pouring into Jake's ass. Jake threw his own head back and howled as well, accepting the seed that his most gifted and talented lover had given him. The two howled together, came together, and basked in the splendor of the night.

****

A heaving gasp broke Jake from his sleep as he sat up suddenly in bed, sweaty. His chest rose and fell as he tried to recover his breath before he looked around in confusion. He was surrounded by the familiar sight of his basement 'apartment'. Grey cinder block walls, a window that was a foot tall and two feet wide with a view of a sidewalk and the shoes of people going by. Rather than a bathroom he had a water heater, washing machine and dryer. His living space was a utility closet half underground, but for it he'd been thankful.

Jake threw off his covers and stumbled out of bed, making it a few steps before he stopped, looking around again. He didn't remember coming home... or honestly what had happened in general. His blond hair was caked with sweat, his nipples were hard, his muscles were unusually pert. Jake took a few steps before he felt something hot and slick running down his ass. He turned and tried to look over his shoulder but couldn't. Instead the young man reached back, ran his finger through the liquid and brought it up to his nose.

The aroma was intense; salty, musky, earthy like peat and most, with a tang of... rust. Jake realized what it was, that sex had been one of his evening activities... but with who? Where? The last thing he remembered was going for a job, a petty job. He'd gone to the junkyard and hopped the fence and... that had to be it. He must have hit his head on the other side! A mild concussion, then maybe he went to the bar and tracked down a cute guy, had a bit of a fling. He wasn't normally on the receiving end, but maybe brain trauma did that to a guy.

Yes, that had to be it! A concussion and alcohol led to the dream of being fucked by a demonic junkyard dog. For all he knew, it was a bad drug trip! Yes, that had to be it... It was unfortunate really, Jake liked to remember his sexual conquests, or in this case, being conquered? Still, he had a job to do - more or less. He stretched out, wriggled his shoulders and made his way to his closet. Getting dressed was strange, feeling his black t-shirt hug his body tighter than he was used to. Maybe it shrunk in the dryer. It felt tight around his biceps, tight across his chest too. He pulled on his underwear, a little taken aback by how well they showed off the curve of his ass cheeks and his package. He grinned a bit, pulling on his jeans next. Before long he was ready, ready enough to head to work.

The Roanoke building was old; old enough to have a metal frame elevator rising up through the center, one that had been operated by a door man originally. The beige walls contrasted with the rich red wood banisters and guard rails set on black wrought iron moldings. It was an old building with old amenities and it was up to Jake to fix them. He'd started with the usual stuff, clearing drain traps and cleaning air filters... though his work had become a bit more complex thanks tot he polarizing reaction of the dogs in the apartment. Before they hadn't paid him much mind, but now? They loved him or hated him... They barked at him or tried to hump his leg. Jake was a bit shaken, thinking back to his weird dream. Maybe it was just some weird time of month? Jake was making it down to the second floor when one of the apartment doors opened up and a woman in her late sixties leaned out.

"Excuse me, mister Walker, if you could spare a moment?" The woman called out, her voice carrying an old aristocracy. Jake hesitated before he moved back up the steps, climbing to the landing to face her properly.

"Yes, Mrs. Roanoke?" Jake asked softly.

"It is the fifth, today, yes?" She questioned. Jake's shoulders slumped a little. He could already tell where this was going.

"Yes ma'am." he replied. She nodded.

"Which makes it thirty two days since you said you would fix the water heater." She added. Jake nodded.

"Yes, it has taken too long. It's an old model, finding the right element is either expensive or time consuming. I'll redouble my efforts, try to figure something out." he said. Her eyes narrowed a bit.

"See that you do, figure it out, or you'll have to figure out another form of employment." She said before she closed her door, leaving Jake there. He shook his head and moved down the steps.

The sky looked like it was on fire, the clouds taking on shades of red, orange, amber and gold. The clouds drifted along at a languid pace, and the city lights were growing brighter as well like a glittering pile of jewels. It was hard to think that such beauty was visible outside of a junkyard, but Jake knew that what he needed was hard to come by, and he'd already failed once. He stood outside the back fence, waiting for it to get darker. He took a puff from his vape pen and exhaled, the smoke billowing out from his lips, curling around the longer, softer, blonder hair hanging down from his chin.

Jake couldn't help but feel oddly... good... about things. He was clear headed this time, prepared, ready. He knew what part of the junkyard the element was in. He'd steal it, install it, then charge Mrs. Roanoke half of what a new one would have cost. His rent would be made for months, and he'd have a tidy sum to splurge on himself with. He took a few more puffs before he put his pen in his jacket. He tested his gloves, making sure that they were ready to face barbed wire again.

The fiery colors of the clouds gave way to cooler tones; violets, blues and then finally darkness. Jake nodded to himself, backed up and then charged. He sprung from the dirt, grabbed onto the fence, hoisted himself up and over. He landed on the other side and rolled a little to get rid of his momentum. Springing back up, he brushed the dust off and grinned, heading through the yard. He glanced over his shoulder, looking one way and then the other before he saw it.

Sitting in the corner of the lot was a huge, fire engine red water tank. The gauges were broken, the pipes bent. It had been torn out in a hurry, but the embossed metal manufacturing emblem was the same as the one in the Roanoke building. Jake darted over, pulling out his tools. He made it to the water heater, his wrench latching on. He had to fight rust, grime, and the passage of time but eventually he popped the outer seal and started to get everything to turn.

With the speed and diligence of a pit crew, he got the bolts off, the cover plate dropped, and his hand reached in, unscrewing the element. It slipped out into his hands and his eyes scanned the contacts. It was perfect... It had years of life left in it. Jake wrapped it in a cloth to protect it before he returned the cover plate and tightened the bolts just enough to hold it on, not wanting it to be obvious that he had purloined the piece.

Jake sprung back up and spun on his heels to leave - only to realize his path was blocked by an immense, gigantic, growling dog - the dog from his dreams. The Doberman was bigger than before, standing taller than Jake's waist... and it was wider, too. Muscles rippled beneath its hide... and so too did bulges, the dog's head shifting as horns began to slide out and a ring of fire erupted around its collar. Jake's jaw dropped.

"Oh my god, it wasn't a dream..." He whispered. Jake murmured, turning, trying to climb the water heater. His hands grasped at the metal, but it was too round, too curved. The guard dog charged, its chain rattling. It closed the gap and lunged. Jake grunted, knocked clear of the tank, landing in the dirt. The dog growled, the sound reverberating through his body. His ass suddenly twitched, his cock went rock hard, and his nipples went pert.

"What the fuck?" Jake moaned, but then moaned harder, rolling onto his back as his cock got painfully hard, stretching out tighter and thicker than it ever had before. The dog shuddered and shifted, ligaments stretching, hide expanding as it rose taller, broader, longer. The beast was almost the size of a donkey. Jake felt fear deep in the pit of his stomach, but it was as if his body didn't understand the concept. He felt a hot, slick wetness starting to spread in his pants - not pee, like he thought, but pre.

The dog gave a resounding growl before it lunged again, ramming Jake with its head. Jake toppled to the ground and then yelped as his pants were clawed through, torn asunder as if they were made from tissue paper. There was a flurry of movement and Jake got a face full of dust. He coughed and clawed at it before he gasped, feeling something hot, slick, full and wide spear into him... again.

He gasped, hearing the junkyard dog pant behind him as it started to thrust and grind and pump. Jake wanted to be terrified, but his cock twitched and pulsed as if it was trying to milk the beast. He drooled a little before he caught himself, but then he started to feel his eyes glazing over as he actually started to enjoy it. Ever so slowly Jake started to thrust back! He couldn't believe himself, but he didn't care. He felt shivers of pleasure wash through his body, and he didn't want it to stop.

Jake's lips twitched into a manic, crazy grin. Maybe he was losing his mind, but it felt too good not to embrace. A hand slipped under his battered body, grabbing onto his own hard, full cock, working it as his ass was filled. Jake closed his eyes, bouncing between the cock in his ass and his own, going faster, harder, deeper. The sounds of the panting, the claws in the dust, the movement and the impact became hypnotic.

Minutes passed, and then Jake heard a change in the junkyard dog's breathing. It became more rapid, uneven, irregular, and then he felt the blossoming of an incredible heat in his loins, spreading in - only to be pushed and churned into his body by the ramming cock. The dog was still fucking him as he came - and came - and came. Each thrust pumped more, pushing the previous load deeper and deeper.

Jake moaned harder, feeling the seed curve and spool through him until it reached his stomach from the other end, pooling in, flooding it, filling it. Jake's eyes shimmered faintly, the irises turning red for a moment before returning to normal. He drooled more, feeling his stomach reach capacity and then keep going. He moaned harder, his stomach starting to stretch, pushing out a little, then a little more. The remnants of his shirt rode up, exposing more of his newly formed belly. The junkyard dog panted a few more times before finally pulling off, a feat made difficult by his swollen cock, but with a pop the beast was free. He wandered away, seemingly satisfied, leaving Jake in the afterglow of such a strange encounter.

****

The walk home had been the definition of a walk of shame. Jake's clothes were shredded, his belly bloated with dog cum, and his cock was still hard. The cover of evening had been some help, though he'd gotten a few strange looks from the few people he'd passed. It was even harder to explain the large heating element he carried, his duffel bag having gone missing... but he returned to his apartment victorious.

The work in the basement was dark, cold, and felt particularly difficult after his experience, but after an hour and a half he'd slid the element in, locked it in place, hooked up the connections and sealed the unit. Once the water was back on, all the dials indicated that the temperature was climbing. The only thing left to do was wait... and to rest.

Jake returned to his subterranean lair, barely getting out of his torn clothes before he collapsed face down in his bed, surrendering to sleep in moments. While his mind sank into unconsciousness, his body was more active - unable to find that perfect spot, to find the peace it desired. As Jake tossed and turned, the minutes ticked by. The darkness outside was giving way to brighter hues and golden light.

After a few hours, Jake's restlessness became a reluctant acceptance that he had stayed out too late, that he had to start another day. At least with the element in place, he'd have his windfall and the pressure of the job would drop. Jake begrudgingly forced his eyes open as he sat up, pulling the blanket off of himself. What met him was an incredibly tall, oddly wide tent rising up from his boxers. Jake swallowed a bit.

Had the dog beast awoken something in him? Maybe... maybe he was gay, and needed to find a nice man to pound him in the prostate... The alternative was even harder to accept. Still, the hard work was done, he could afford a little time to play. He licked his lips and tipped his head back, his heavy earrings wobbling as his hand slid his boxers down and wrapped around his hard, swollen cock.

Jake moaned harder, panting. With each rise of his chest, it came back down a little less. His pectorals firmed, his abs hardened. New wisps of hair began growing under his arms, thickening, taking on a goldish-red hue. The invisible hairs on his chin started to turn blond, thickening a little as he pumped that shaft. Even his fingernails were darkening from ivory to brown and then black.

Soon the repairman was thrashing in his bed, jutting his hips up, forcing his cock through his altered fingernails. If anything, the rod was getting harder. More blood flowed in, forcing the cock to shift from pink to red to almost purple in tone. The base plumped out, bloating wider and wider. Jake rolled the palm of his hand over the tip, but felt something very strange... He felt a bony like protrusion.

Jake's blue eyes opened and he looked down, gasping as he watched the mushroom shaped tip stretch, curve, contort and taper into a point - a point just like the junkyard dog had. His cock had a canine tip, a canine base... and a retracted sheathe. Jake was caught off guard by the changes, but also his orgasm. He gasped, moaned, and then howled, throwing his head back as a tiny spurt of human cum leaked out of his cock just before a thick, huge jet of yellowed dog sperm fountained out, splattering across his stomach, his chest, and his short goatee.

The thief shuddered, eyes glazed over with lust, feeling as if he'd just had the best sex of his life... and that his cock wasn't any less hard. His body was still raring to go, ready for more, and he could barely think. He laid back on the bed, inhaling the scent of his own cum, thinking about what had happened when he heard a strange noise... It sounded almost like a growling stomach, but it was too low, it was... coming from his... ass?

This time Jake felt it, his pucker squirming and pulsing, hungry for a cock - a cock just like the one that had filled it the night before. Jake licked his lips again, feeling a strange mix of shame and need. Whatever the junkyard dog had done to him, it had changed him. He wasn't the same Jake anymore, but in a strange way he didn't want to be. All he wanted was to feel that cock in him again, filling him again. Jake stumbled out of bed, cum still dripping from his hardened muscles as he looked around for clothes suitable enough to get him back to the junkyard.

****

The junkyard looked different during the day. For one thing, it wasn't locked up tight. Jake walked through the gate, blue eyes peering out from under his gray hood. His sweatpants were loose and baggy, but still barely hid his huge, hard canine erection. He peered around as if he was on the prowl, looking for the best treasure of all... but this time it was no score, no piece of hardware. He moved around the corner of the old battered storage building, heading to where the chain had been.

It was a little more out of the way than he remembered, but the red dust was caking his shoes, kicked up by his walking. When Jake finally heard the growl, a shiver ripped through his body. He slowly turned, his jaw dropping as he laid eyes on the magnificent, gigantic beast. The junkyard dog no longer clung to his Doberman persona. He was nearly as tall as Jake was, hundreds of pounds of muscle, black horns glinting in the mid-day light. His fangs dripped with thick saliva.

The hellhound stepped forward and sniffed the air, then lowered his head and sniffed again before he let out a bark. The bark shook Jake and he moaned, his newly changed animal cock leaking pre suddenly, his sweatpants getting soaked. The hellhound growled happily before it spread its front legs, revealing the wobbling, bobbing head to its enormous canine cock that reached almost all the way to its front legs. This time it was Jake's mouth that started to leak uncontrollably.

Jake felt like he'd lost his mind. Here he was, feeling drawn to a horse sized demon dog... but how could he help it? They were connected. Jake reached down and lowered his sweatpants, letting his dark red canine cock spring up into the air, flinging strings of pre. It was swollen, hard, plump... but not nearly as big as the guard dog's. The beast looked into Jake's eyes and Jake knew his place. Before his sweatpants even fell around his knees, he dropped to the ground and leaned forward, his tongue sliding out from his lips.

The beast growled happily as it felt the wide, flat human tongue hit his hot rod. Jake began to slide back and forth, nudging up beneath the beast's legs. He licked and slurped, slathering it in saliva before he returned to the tip and began to push forward. The guard dog growled happily, feeling the pressure and the resistance of the human's lips. Jake seemed well practiced as the pointed tip popped into his mouth, followed by an inch of shaft, then two, then three.

Jake grabbed onto the dog's legs as he bobbed his head. To do his part, the demon beast began thrusting and humping his hind legs. Jake felt the rough impact of the cock head on the back of his throat, but he didn't gag. If anything, it sent odd waves of pleasure through his body to feel. Whatever had changed him had gripped him deeply. His eyes slipped shut and he surrendered himself to the experience, blowing the hellhound that had caught him so completely.

The dog huffed as he humped, and soon Jake was having to tip his head, allowing the dog dick to slide all the way through his mouth and down his throat. It was enormous, huge, thick, and musky. His mouth was starting to taste like nothing but rancid cum... and somehow Jake felt even more turned on by that. His own canine cock was dribbling pre, but it was also starting to swell again, growing up along his stomach, pushing past his navel as the base bloated wider like two baseballs.

Unlike a human, the hellhound seemed to have little sense of tempo or style. His thrusts were ragged, desperate, animal, and unrelenting. Jake's throat stretched around the massive tool, still only able to get about half of it down. Jake was trying to get even deeper when he felt an odd pulsing around his lips, and then felt the hot blossoming of cum starting to spray directly into his stomach. His own cock quivered, and Jake did his best to grin around the cock in his lips before he decided to push down as far as he could go.

Inch by inch, the shaft squeezed between his lips, sliding further down his throat as it unleashed its lusty fury. Jake was barely able to make progress, it was nearly too wide to swallow, but he mounted himself as far as he could as he felt himself filled up... Only then, impaled, stomach filling rappidly, did he realize how long it had been since he had taken a breath. Somehow that need seemed less urgent, less neccessary.

Jake squirmed a little, amazed by how hot his stomach felt, how full. He could feel the cum sloshing around inside of it, but the hellhound kept cumming. The beast drooled, the saliva dribbling out into Jake's hair where it sizzled, adding silver streaks to his already blond hair. Jake's stomach started to stretch, distending outward as more and more cum was poured into it. The skin grew tight like a drum, rounding outward, growing... and growing... and growing.

It took several moments before the flow finally dribbled to a stop. Jake wobbled in bliss, moaning, feeling completely full. To his surprise, though, the hellhound started to waddle backwards. Jake braced himself for the unsheathing as the massive tool slid back, coming out of his throat and mouth, inch after inch before it popped free. Jake dropped down onto his hands and knees, panting for breath, moaning and grinning. He lowered his head, his sweat soaked forehead resting in the red dust where it caked to his forehead.

Jake could hear the hellhound moving around him, but he was too spent to focus or think - at least until he felt something hot, hard and bony pushing at his pucker. Jake gasped, lifting his dusty face, eyes widening as suddenly that hot, wet cock that had just filled him so full from one end was pushing into his other. There was no lube, no pre, not even spent cum to coat the cock. His throat had cleaned the shaft of all of its natural juices... But still it pushed in, radiating with the heat of friction.

The hellhound drooled more, panting heavily, thrusting and huffing. It seemed quite content that this human was its mate now, and it was intent on doing it right. The horse sized dog pushed in inch after inch, loving the strange moans and whines the human made. He moved faster, deeper, harder. Jake was thrown forward and back at the whims of the hellhound, feeling his ass stretched. His cheeks pushed apart to make room, his pucker loosened.

The beast pistoned in and out, faster, harder, deeper. Jake moaned loader, grunting, feeling his cum filled belly sloshing around with the impact. He reached down to wrap his hand around his own dog cock, realizing it was so big he could use both. As the second hand coiled around his huge, red rod, he started thrusting into his hands, then bouncing back against the intruding cock.

With one powerful thrust, Jake was knocked forward, but he didn't let go of his cock. His head hit the dust and he coughed and sputtered, double fisting his erection as he felt the huge beast slide through his colon, making impossible progress, perhaps even re-designing the layout of his intestines as he got deeper and deeper until Jake's eyes widened, feeling the dog beast reach into his very soul.

It wasn't physically possible... but his anatomy had changed. Jake came, unleashing his own tainted dog cum across his stomach and the ground. The smell was musky, earthy, spicy... but his orgasm was nothing compared to the feeling of being filled by so much of the hellhound's cock. His stretched, gaping pucker was throbbing from the assault, but the hellhound had stopped thrusting. He didn't need to because there was only one last thing to do.

With a gentle ease, the hellhound started to push forward one last time, stretching the human's ring as the bloated, swollen, rotund knot at the base of his shaft finally found a home. Jake's eyes fluttered, his mouth hung open and then he gasped as the hellhound popped into the human. His already full belly stretched much wider, and Jake swore he could feel the cock coming for his throat from the other end. He had no idea what was going on, how anything fit, but he didn't care. He belonged to the hellhound now, this was his life.

The junkyard dog raised his head to the heavens, opened his maw and let out an unearthly howl. Jake lifted his head and did the same just as his alpha, his lover, his beast began to cum again. This time, it was different. This time it was complete. The heat blossomed through Jake's body, pumping through his veins, scorching his soul, burning away parts of his mind. Jake came and came, spraying his cum across his body, his nipples as hard as diamonds.

The moment felt like an eternity, maybe even longer. The mid-day sun started to set before, finally, the hellhound began to relax. It took many more minutes for the knot to soften enough, and when it did, the hellhound popped out of Jake, withdrawing feet of cock until Jake was left as a drooling, panting, quivering mass of well spent sexual energy. Jake collapsed onto the ground, covered in cum and red dust and sweat. His lungs burned a little so he rolled over onto his back, splaying out on the ground.

He could feel the setting sun keep his body and his swollen belly warm, soaking into his skin, his body feeling oddly content. He murmured softly, legs spread, arms at his sides, unaware of the hooves walking through the red dust, coming closer and closer until a shadow fell across Jake's body, blocking the sun. Jake opened his eyes to look up, gasping slowly as he saw the owner of the junkyard... and his horns.

The man barely fit the definition of the word. He was over six feet tall, his shoulders as wide as a bull's. His skin was well tanned, but with unnatural reddish hues like the rusty dust that filled the junkyard. He had on aviator sunglasses that hid his eyes, but they did nothing to hide the ribbed, jet black horns curving out and up from his forehead, let alone his pierced, pointed ears. The tattoos on his arms seemed to keep moving, ink serpents coiling and releasing, never stopping.

"There you are, you've been a naughty boy." The demon said with a reverberating voice, crouching down. Jake felt something cool and firm slip around his neck, realizing only a moment later that it was a leather collar. As it slipped shut, Jake felt a shudder of pleasure rip through his body as the blue in his eyes burned away to a rich crimson color. The demon reached down to rub a clawed thumb along the patch of fuzz on Jake's chin, adding a streak of silver down the middle as the hair grew out to an inch long, then two, then three. Jake's ass cheeks started to clench and unclench involuntarily like a subconscious tail wag.

"Who-" Jake muttered, panting. The demon grinned.

"I'm your master, that's all you need to know for now. And you're going to pay off your debt by guarding my treasures." The demon said. Any number of things crossed through Jake's mind to say in response, but when his lips parted, only one thing came out.

"Yes master." He replied. The demon growled happily and stroked Jake's chin again, admiring his handiwork.

"Good boy." he said, "I'll go get you some dog food. You've gotta keep your strength up, especially now." he said with a smile, patting Jake's swollen belly before he stood up and moved back toward the main building. Jake looked down at his stomach and then over at the hellhound who was currently staring at him with adoring red eyes. Somehow, in some strange and twisted way, it still felt better than working at the Roanoke. Jake ran his hand over his belly protectively, feeling its curve, wondering just what his new job might be like and how he'd be able to bring pleasure to his master.
