Highway to Hell Written by Leo_Todrius and Kybal_Lutra

A scorchingly hot wind blew along the black top, sizzling and searing with rippling waves of distorted light. The air smelled of dust and exhaust, swirling together in a potent, heady mix. The rocks were sun baked, the succulent plants deprived of even the little amount of water they clung to year round. It was an inhospitable environment for any of the poor creatures not hiding in a burrow or under a rock, but especially so for Riley.

The young man looked like he could have been a model for Abercrombie and Fitch, though the filter on his pictures would most certainly have to be considered 'road dust'. His hair was a bit longer on top and shorter on the sides, grow with an all-American shade of chestnut brown. There were a few faint flecks of freckles on his fair nose and his chin was pointed. He had on a gray tank top and brown cargo shorts, allowing Riley's arms and legs to get a bit too sun kissed.

He slowly walked backwards along the road, holding a hastily made cardboard sign emblazoned only with the word 'South'. His baby blue eyes were watering, looking through the searing hot air for any hope of salvation to his particular predicament.

Hot rubber rolled across the burning blacktop at a blinding speed as a massive 18-wheeler crested the slight hill the young hitchhiker had walked over a few minutes ago. The semi's engine roared with power and barreled down the highway towards the lone figure still walking on the side of the blacktop. The truck was monstrously huge, spouting thick streams of black smoke from its numerous chrome exhausts, the red and orange flames painted down the side of it's long trailer only adding to it's hellish appearance. Suddenly, a blast from the mounted horn on its cab sounded across the flat landscape, sending an echo out for miles and miles. The rumbling growl of the engine began to soften and the enormous rig started to stop, tires squealing in protest as the cylindrical breaks glowed red hot, working hard to stop the weight they carried.

Riley watched in shock as the massive object started to slow itself. It was a dramatic showcasing of the fact that he was about to catch a ride. The young man gathered himself up, tucking the cardboard sign into his pocket as best he could as he anticipated the stopping point of the big truck. He walked backwards a few yards, watching it approach.

As it slowed down more and more, the truck seemed to shudder against its frame, almost as if it couldn't contain its own glee at the prospect of picking up the hitchhiker. Finally, with a great blast from the air brakes, the truck halted next to the young man on the side of the road, its engine still growling like some unearthly monster. The passenger door unlocked and swung open, the groaning hinges sounding like they hadn't been used in quite some time.

There was something about the moment that stretched reality, reaching beyond itself. It almost didn't feel real, as if the moment itself was bending and twisting just for Riley... but the young man didn't notice, didn't sense the strangeness surrounding him. He lunged for the open door and flung himself upwards into the unseen cabin, landing on the luxuriously plush seat. Before he even checked his surroundings, he quickly swung the door shut in a vain attempt to capture whatever cooler temperature the cabin had from the heat outside.

"It ain't much cooler in here, kid." came a gruff baritone voice from the driver's seat, "But I got a feelin' you won't mind a little bit'a heat in exchange for the free ride. Sweatin' builds character, 'mong... other things. Where ya headin' anyways?"

"Just south, south of here I guess. How far are you willing to take me?" Riley asked, getting a good look at the driver that was offering him such generosity.

He was a veritable mountain of a man, clutching the wide wheel of the truck with two meaty hands thick with corded muscles that ran all the way up his arms and shoulders. He wore a checkered, button down short sleeve shirt that was wide open, showing off his plump pectorals, each bulging with fat and muscle above his equally impressive beer gut. A thick, black beard covered his jaw and neck, almost reaching his substantial pelt of chest hair that led down his stomach and disappeared beneath his dark blue jeans. A healthy head of greasy, unkempt black hair grew from his skull, the tangled mess just lengthy enough to cover the tips of his ears. Finally, he wore a pair of dark sunglasses over his eyes, which seemed to almost glow with glee from behind the shaded lenses.

"Kid, I'll take you to hell and back if that's what you want." he replied, laughing deeply with a wide smile, "How 'bout this: I'll drive 'til you say you wanna get off, and I promise, I'll get ya off right then and there. Think ya can handle that?"

"Sounds perfect to me! I think we can come to a good arrangement. It'll be a lot more relaxing like this than being stuck with some uptight prius driver for ten miles before I'm back where I started." Riley smirked, looking around at the Cabin, "Is this your rig? Or do you drive it for someone?" he asked, eager to get the driver to be comfortable with his presence.

The big trucker smirked in his seat as he shifted the gearbox down into neutral, operating the complex dashboard like it was nothing, pulling and flicking switches as he clutched and hit the gas, moving the big rig forward as he shifted into first.

"Yeah, I got a boss. Lotta people ain't seem to like him all too much, but me 'n him gotta nice thing going. I haul his loads wherever he needs 'em and in return, he gives me... special privileges." He glanced over to the hitchhiker in the passenger seat as he shifted up a gear, giving the thin, attractive boy a once over from behind his dark shades, "I'm Rex, by the way. Don't often get the pleasure of havin' such handsome company comin' along for a haul like this, so by all means, get as comfortable as ya like. We'll be drivin' for a while."

Riley shifted a bit, blushing in a moment of pride at being called handsome. Somehow it didn't seem strange for this man to call him that, only that it was the first time anyone had said such a thing to him. He'd felt sort of generic back home, run of the mill. Any attention was good attention.

"Thanks. I'm Riley, and this really means a lot. Driving is going to be a hell of alot better than walking." Riley said, leaning back into the plush seat. The air smelled musky, rich and masculine. There were hints of sweat and yet it was almost savory, comfortable.

"You bet yer cute ass it's better than walkin'. I came up over that crest back there when I saw ya, and I couldn't help but stop." Rex said, his voice deep, almost velvety as it rumbled over the din of the massive engine. He shifted up again, finally getting the truck back up to speed as they barreled down the seemingly endless highway. "Why're ya walking all alone in the middle of nowhere anyway? Ain't got no family? Girlfriend? Boyfriend?"

"Nope, got nobody. Lived a nothing life and I'm looking to start a new one. One long stretch of road between me and my new beginning. What about you? You have someone back home, or someone in every port?" Riley asked curiously.

Rex smiled as he leaned back into his seat and grasped the wheel with one hand, "Nah, no home to speak of, 'cept the one we're sittin' in. Suits me better anyway. I love the open road too much to settle down. 'Til I find someone who loves it as much as me, that is." he said with a wink as he glanced over at Riley, "Of course, me 'n my boss still fuck around every once in awhile, usually when I head back his way to restock. He's... well, he's almost worthy of worship when it comes to fuckin'."

"I hope I meet someone like that someday, someone that would be content with me anyhow." Riley murmured, "So when did you come out? Let the world know what you liked, and that you didn't care what they thought?" he asked, feeling the truck picking up speed again.

"Kid, I ain't never cared what the world thought. Only knew what I prefered and that was that." he said gruffly, slicking his hair back with his free hand, "If I wanna fuck a man, I'm gonna fuck a man. And if I wanna suck his dick and rim his ass beforehand, I'm gonna do that too. Ain't no amount of disagreeing from some hypocritical, homophobic fuckass gonna stop me from doin' what I know I enjoy." Riley gazed at the driver with admiration, leaning back into his seat. A grin crossed the young man's face as he leaned back in his seat.

"I hope I can be that way one day, be as free as you." Riley said with awe.

Rex turned fully to look at Riley, a bushy eyebrow rising up from behind the thick, dark sunglasses he wore. "So what's stopping ya? I'm the only one here, kid. That's the allure of the road: you can be as free as you wanna be. You won't see me complainin'."

"But where do I even start? It's a long ride, but is it that long?" Riley smirked, looking to the big man with a weary smile.

"It's as long as ya need it to be, Riley." Rex said, his eyes glowing slightly behind his shades once again. He reached over and placed a meaty hand on the hitchhiker's thin shoulder and squeezed, "I ain't goin' nowhere, so why don't you just... well, again, get comfortable. I don't bite, 'less you want me to." He finished with a wink.

Despite the heat, despite just meeting the man, Riley felt an odd sense of kinship with the big trucker. He looked at him for a moment, considering his options and then scooted over closer to Rex, sidling up to his thick body until they were hip to hip. Ever so gently, the young man leaned his head over onto the broad, meaty shoulder of the bearded behemoth behind the wheel. It was oddly fulfilling to find someone so open, so accepting. It was as if he had found himself some sort of savior.

Rex grinned as he felt Riley lean against him, the smaller boy's slight frame fitting nicely next to his own. He switched hands, placing his left on the wheel and bringing his right back and curling it around Riley's body, letting his own unnaturally high body temperature flood over the boy. He smirked again as he felt a slight stirring in his groin, knowing that he had to pace this out properly if he was going to succeed.

Despite the intense heat of the desert and the stuffy air of the cab, the heat pouring off of Rex was oddly comfortable. Riley's eyes fluttered shut and he soon passed out, lulled into unconsciousness by true comfort and the sound of the road passing beneath his feet.

---

The growl of the tires had stretched into hours of a steady, hypnotic hum. The heat of the day had crested, but the heat of the cabin had continued to climb. If it hadn't been for a few bumps in the road, Riley would have kept sleeping, but instead, his eyes slowly opened and he blearily looked out across more desert road, a blood red dawn just starting to tease it's entrance over the dark horizon. Riley's grey tank top was soaked through with sweat and he had a case of morning wood that was painfully hard, straining with urgency against his khaki shorts. He licked his lips a bit, getting the salt off of them before he remembered where he was and who he was with.

"Damn, I'm sorry I nodded off... That was rude of me." he muttered, looking back at Rex, his eyes widening a bit in confusion. Somehow the trucker seemed different, like the night had revealed something about him.

Rex was still driving, his eyes scanning the road and a slight smile playing across his lips. But as Riley had noticed, he did seem... different. His sunglasses hung by one thin, metal arm from his shirt pocket, revealing his dark red eyes that seemed to glow in the darkness surrounding them. His beard and body hair both seemed thicker somehow, almost more like fur than normal human hair, and his belly was even more packed with fat and muscle now. Ears that had been round hours before had now taken on slight points, although his thick head of dark black hair made it difficult to notice as it flowed over them. His skin seemed to be giving off a warm, red glow somehow, almost like some sort of hellish bioluminescence.

Seeing the driver in such a state, Riley's morning wood didn't abate in the slightest. He leaned back against his seat, the rod rising up practically like another gear shifter before them both. He blushed bright red but wondered if Rex would give him the decency of not drawing attention to it. Somehow, though, he craved for that man's attentions, his affirmations. He only wished he hadn't wasted so much of their time together by being asleep.

"This bench is really comfy." Riley muttered, trying to get the conversation rolling again.

Rex looked away from the road for a moment to gaze at the drowsy kid that had been sleeping on his shoulder for the past eight hours. He knew that by now, his musk and the truck's energy would've had enough time to sufficiently affect the boy's mind, to make his now more demonic appearance seem natural to him. Rex grinned at the prospect of what was to come, his arousal already tingling with need.

"G'mornin' to ya too, kid." he said, rubbing his hand across Riley's back, the slight black claws now growing out of his fingers scratching the boy and making him arch his back in pleasure.

"Sounded like you were havin' a good dream fer a while there. Don't often hear so much moanin' in here, unless it's coming from me." He ganced down at the boy next to him as he continued to scratch his back through his thin, damp tank top.

"I wish I could remember it now, that sounds like that would have been a great dream." Riley said, looking down at his unabashed erection, "Must be where this guy came from." he added, his cheeks turning beet red. He had said it to test the waters, though Rex had already proven himself rather open to such subject matters. Still, Riley was testing to see how deep he could go.

Grinning widely, Rex dug his claws a little deeper into Riley's skin as he spoke, "Well, maybe I can help jog yer memory, kid. But first, why don't ya have somethin' to drink? Yer probably pretty thirsty from all that walkin' ya did today." He reached over and pulled a massive thermos from the cup holder on the side of the driver door, handing it to Riley, "This should help wake ya up a bit more."

Riley's stomach rumbled at the mere thought of anything to eat. Come to think of it, he hadn't eaten in almost sixteen hours. His stomach started to growl and gurgle as he took a hold of the thermos and eagerly spun the lid off. As the cap came loose, the contents inside sloshed and swirled, but it was unlike anything Riley had ever seen before... It was darker than coffee, thicker than oil and reminded him of the blackest midnight he could recall... But at the same time it had a blood red quality to it. It absorbed the light, it absorbed everything and seemed to exude nothing but a humid heat.

Watching it swirl and slosh, Riley felt almost hypnotized. His mind wasn't frozen in place, it was flowing from strange thought to strange thought. Every stolen glance at a man, every mischievous idea, every darker impulse. Riley didn't even remember pouring some of it into the cap of the thermos until it was there in his hands, but soon he tipped it back, letting it pour over his tongue and down his throat.

It tingled like cinnamon and then burned inside his throat and stomach, the heat radiating outwards until the hairs on his arms stood up on end. His entire body felt for a moment like it was on fire, and then he gasped and moaned out. A huge wet spot spread across the lap of his khaki shorts before cum dribbled out down both pant legs, splashing to the floor of the cab... but still his cock wouldn't relax, remaining impossibly hard and erect in its wet cloth prison.

Rex could smell the almost sickly-sweet scent of Riley's release as he came inside his pants, and he knew that the liquid sin was working it's magic. Reaching down in front of the gasping human, the trucker used his clawed hand to pop open the button on the boy's cargo shorts, letting his rock-hard erection spring out from the confines of the fabric, the tight, damp underwear beneath now the only thing keeping the throbbing length from his bare grasp. Rex's hand glided over the impressive outline of the boy's cock, tracing his now larger claws over the stretched fabric lightly as he teased it. He licked his lips with his longer tongue, feeling it swipe across his more prominent canines as the rest of his body continued to change more rapidly now.

"How ya doin', kid?" Rex asked, his voice even deeper and more hypnotic than before. He shifted slightly in his seat, his own trapped arousal easily eclipsing Riley's.

"Don... Don't stop... feels... too good." Riley panted, sweating and hot and horny, looking down at his brief clad cock, soaked through with another man's hand so close to it. Riley felt so vulnerable and yet so free at the same time, but he felt different too. After drinking that stuff he felt hot and hollow at the same time, craving to be filled by something, by anything.

"You smell so good, kid. Just like a demon should. C'mere...." Rex reached down as he maneuvered himself a bit, grabbing Riley and pulling him into his lap, the trucker's bulging arousal now pressing against the boy's ass through his too tight jeans. Suddenly, Rex let go of the wheel controlling the big rig as he began to scratch and rub Riley's slowly transforming body with both his clawed hands, feeling the boy's muscles starting to twitch and harden underneath his skin. Incredibly, the truck continued to drive forward, the wheel acting of it's own accord and keeping straight on the road and maintaining its speed perfectly. As it drove on its own, the grill seemed to stretch outward and warp, almost like some sort of hellish cow catcher on a train.

Rex moaned deeply as he continued to rub against Riley. He felt his thin, whip-like tail growing from the bottom of his spine and he leaned his head back and sighed as his two thick, pointed horns finally split through the flesh of his forehead, causing a rush of pleasure to flow through his entire body. Glancing down, he saw his skin had finally reverted to it's natural shade of a dark, rich crimson. His limbs were coated in body hair and his chest and stomach had grown a thick pelt of soft, midnight black fur.

The trucker felt his feet burst through his boots, toes melding together and forming hard, glossy hooves as the changes raced up his legs, changing them to a more unguligrade structure. Even the hair on his head changed, gaining a luminance and a luster that had been hidden in his human form. Finally, Rex felt his changing genitals shifting and growing under the fabric of his jeans, made all the more pleasurable by the young man writhing and squirming about on his lap, soon to be a young demon begging with lust and need.

Riley had been giving into pleasure and passion, to lust and sloth and gluttony, to the experience around him - but it was all starting to add up. He felt the change on his skin, on his body, even beneath his ass. He slowly looked down, spotting the trucker's hooves, inhaling sharply in fear and shock.

"What's going on? What's happening?" Riley asked, wondering if he had been dosed with some kind of drug that was playing havoc on him.

Rex let out a sensual moan as the human shifted on his lap, the boy's tight, pert ass rubbing over his aching arousal. The demon leaned forward slightly and trailed his lips across Riley's bare neck, snaking his dextrous, slimy tongue out and running it over the human's skin, feeling the pulse quicken beneath and his body temperature rising steadily.

"Kid, yer about to have yer goddamn mind blown. And your cocks, too, if you're lucky." Rex whispered softly as he continued to kiss and lick over Riley's neck and shoulder, "This ain't no normal truck we're sittin' in, and what ya just drank? That there was concentrated liquid sin, a special concoction the big boss cooked up for me to haul 'round the country. As ya can see, I ain't exactly human neither." He finished with a hearty laugh and then ran his long tongue over Riley's ear, snaking it over the slowly pointing tip as it changed. Riley moaned, back arching, his cock gushing with more fluid as his ear changed and stretched and warped.

"But I didn't ask for this... I..." But Riley's protests were half hearted. His brain was reacting to more pleasure than he had ever felt, and the liquid sin had started to etch out into his soul, making room for more and more debauchery to fill him. He grunted suddenly, snarling, grinding back against what was now apparently twin demonic cocks beneath his virgin ass.

"That's it, kid... just give in to what feels good. What you know is right. Fuck what the world says, fuck what religion says. Just sit back an' enjoy the unholy ride yer about to get." Rex lifted the rapidly changing young demon up off his lap slightly, reaching down to his own crotch and swiping his tight, damp jeans away with a flick of his claws, releasing his demonic tools from their prison.

The demon trucker had two throbbing, magnificent shafts extending proudly from a furry sheath attached to his crotch and lower stomach. Each cock was a deep, dark red, both pulsing with need and leaking a thick stream of demonic pre from their tips, covering their lengths completely and giving them a natural lubrication. His masculine, hellish scent filled the cab of the truck as his massive testicles ached with need, barely able to contain the pent up seed they held. It'd been so long since Rex had been given an opportunity like this, and he didn't plan to waste it.

"If I give in, what will happen to me? Will I go to hell? Will I die?" Riley moaned, starting to think even such a fate might be worth the short term pleasures. His ass was quivering in anticipation, already starting to stretch and grow, preparing to accommodate twin girths of such dominance. He gasped suddenly as the sin continued to swirl around inside him and a ring of red flash appeared around his wrists and ankles almost like cuffs, claiming him.

Rex pulled Riley back down into his lap gently, letting his leaking, throbbing demon cocks rub up against the small of the younger demon's back, feeling his growing tail flick and thrash between his dual shafts. "Ya won't die, that I can promise. Let's just say you'll enter into a... contract with the boss downstairs. But don't worry, kid. You'll get the same benefits I got. Immortality, strength, power, an endless sex drive. And Hell's really not too bad this time of year." He said with a wink, and then suddenly reached up, flipping Riley around on top of his lap so that they were facing each other, his leaking shafts raining pre down over the other demon's tight underwear, the fabric absolutely soaked with cum and musk and sweat.

"Endless? Really endless?" Riley asked, leaning in, squeezing their groins together, smearing the juices across his stomach. He leaned in to Rex and brought his poster perfect lips to the trucker's bearded mouth and began to kiss him, humping the driver, feeling his own human shaft bouncing between two mighty pillars of demonic corruption.

Rex moaned as the young demon kissed him passionately, their burning hot lips meeting each other again and again, steam starting to roll off their bodies as beads of sweat evaporated. He thrust his larger, longer tongue into the boy's mouth, tasting his sweet saliva and gasping at the demonic energy that was coursing through it. Swiping his tongue against Riley's one last time, Rex pulled back, getting a good look at the changing demon sitting on his lap, feeling his burning skin against his own.

Suddenly, the larger demon felt a surge of heat flaring up against his lower body and he looked down as bright flames flickered and burned against him and Riley. The younger demon's underwear was quickly disintegrating off of his body, unable to withstand the intense, hellish temperature of his reddening skin. The flames continued to burn pleasantly against the two demons, the dark smoke from the burning fabric swirling around them and mingling with their musky pheromones and scents. Rex breathed deeply, loving the way Riley's smell was changing, and he looked down at the boy's crotch, the flames finally revealing his still average human cock, although it was leaking precum like a firehose.

With a quick flick of his hips and a will powered intent on relaxing his ass, Riley brought himself down on the twin spires of meat beneath him. They plunged into his hole, stretching it wide, filling that aching void inside of him. He shuddered, hissing and writhing, frothing at the mouth as the crimson bands on his wrists and ankles started to stretch outward, bringing with it tougher skin and swelling muscles.

Riley hissed and murmured, feeling his tight sphincter getting stretched. The flesh cried out at the strain, but when the pain reached a pinnacle point, it came with the strangest feeling almost like his anus was stretching like rubber, until once more it was tight and unrelenting. Riley gasped at that, hunching forward, panting hard and trembling in excitement. His fingernails dug into his palms as he felt the growing heat inside of him.

Rex grinned as the boy slide down onto his dual spires of throbbing demon dicks, feeling the changing human boy's tight hole wrap around his shafts like a vice, practically milking his demonic precum straight out of his tips. He leaned forward, bringing his hands around the boy's back, feeling his body's temperature climbing higher and higher underneath his reddening skin and growing muscles. Tilting his mouth closer, he wrapped his lips around Riley's, kissing his deeply as he began to thrust up into his ass. Rex could feel the brush of a thick, growing beard against his own, and knew that the human wouldn't be so hairless in a few moments.

It had started like an ember falling into a dry field, but soon a dusting of black bristle spread across Riley's bare cheeks. It was thickest above his lips and on his chin, but all over it was edging out of his flesh with surprising dedication. Riley had been shocked to be fucked by a man, let alone getting into more than one position on his dual cocks already. His legs rested along Rex's thighs, his ass engulfing the twin cocks beneath him. He pushed his own lips to the trucker's, not heeding their safety on the road at all. Riley's lips worked overtime, playing and parting at the driver's lips, his tongue trying to dance inside and explore what was beyond.

Still smirking as he drove his body up into Riley's eager hole, Rex deepened their kiss, plunging his slimy, dextrous tongue further into the boy's mouth, scraping it over his teeth as the grew sharper. As the saliva spilled and pooled down Riley's throat, the hair that had started to blossom over his face truly took hold. Thick strands emerged from his upper lip, coming down in curls over his lip, meshing into the mustache of the truck driver. Riley's cheeks grew darker and darker until the flesh beneath disappeared entirely. His cheeks filled in, his sideburns got bushy, his chin got wild and still it grew. Moment by moment, with each heartbeat, the young hitchhiker was developing a beard that looked as if it took months to grow, like he had been wandering the roads for a year or more.

At the same time, Rex moved his hands further down Riley's back, landing them on his parted buttocks. He firmly gripped the slabs of fat and muscle, massaging them deeply, running his thumbs over the small of the boy's back as he felt the start of his tail beginning to form. His tongue was now reaching far down Riley's throat, filling his gut with demonic saliva and coating his esophagus, his sinful spit already working it's magic on the young, transforming demon.

Riley was beside himself with pleasure, writhing and bouncing on the twin cocks. It was extremely easy given his leg placement to rise and fall, but each time he fell, it felt like he was going deeper than ever before. Soon his firm and fit stomach was distending with the bumps of twin cock heads buried deep in his gut. He moaned and groaned, sweating and panting, his pert ass cheeks prying apart as a tail slowly pushed out of his backside. His tailbone had started to grow extra segments, each new bone forming in between the others as muscle and ligament stretched out over it all. The flesh was furiously red, the nub stretching into a serpent like growth, whipping around, slapping against the wheel of the truck.

Wrapping his lips around Riley's, the demon trucker thrust even harder into his growing ass, feeling the hard muscles and fiery skin working over his shafts, thick precum pouring into the waiting hole as he worked. The kid was coming along nicely and Rex knew there was much more to change. Slowly and sensually pulling his thick tongue out of the boy's throat, Rex leaned back and ended their kiss, slathering his tongue over the boy's newly grown and now massive beard. Then suddenly, he drove his hips up hard into Riley, feeling his balls starting to churn with his demonic seed as he leaned down and flicked his tongue over the hitchhiker's hard, pink nipples. Rex moaned into the boy as they perked up as he worked his mouth over them, quickly switching from one to the other as he rubbed his hands over the other demon's thickening pectorals.

Riley's panting changed, becoming shallower and more rapid as his chest was worked. His pecs were filling out with muscle, firming and rounding, but fat started to sneak in as well. They got a good bit of pudge, filling out as the nipples spread wider. They grew from the width of dimes to quarters, then silver dollars. The sensitive, erect nubs darkened from pink to red to purple, stretching out like thimbles as they were accosted.

Riley moaned, throwing his head back, grunting as his colon massaged and milked the cocks inside of him. The hot sweat rolled down his scalp, tainting his hair. It darkened from chestnut to mahogany and then a soft black, the long dusty and oily strings turning as dark as night as he road the huge trucker.

Sensing that the young demon was ready for more, Rex slide his hands down off of Riley's chest, raking his hard, black nails over the changing skin of his stomach, feeling the bulge of his own two cocks thrusting against the reddening skin. Still sucking on the pert, now leaking nipples of the hitchhiker, Rex moved his hands even lower, careful to avoid Riley's still human cock as his fingers slide over the boy's thickening thighs. As much as he wanted to take hold of that throbbing, leaking cock and work it until the hitchhiker's cum was splattered all over him, Rex knew that he'd have to save the best for last.

Riley's tail stretched up across the dashboard, reaching four feet long, then five as the tip erupted into a wide spade like shape. The entire length was in a rich crimson, but that red stain was spreading up the spine of the hitchhiker's back while his arms and legs were already dominated. As he moaned and gasped for breath, the glints of light on his sharp fangs made it easy to see just how dangerous the mouth nestled in the middle of his mighty beard really was.

With a bit more meat on his bones and far darker hair, Riley looked much more like he could be related to Rex. They had matching greasy black trucker beards and dark hair, and they surely seemed to be enjoying each other's company.

Rex knew that the newly made demon was getting close to the end of his transformation, but the trucker wasn't going to let that slow either of them down. Suddenly, the larger demon reached underneath Riley's legs, throwing them over his shoulders as he shifted his body off of the seat, pinning the young demon against the dashboard as he began to thrust wildly into his no longer virgin asshole, twin cocks plunging deeply against the clenching orifice and spewing thick pulses of his sin-tainted precum into Riley. Rex's hands laid over his young friend's legs, and he felt them begin to shift and stretch as he drove himself into the other demon's ass, already shifting from human to a more demonic shape.

"Fuck! FUCK! FUCK!!!" Riley shouted out hard, drooling down into his black beard. His toes splayed wide before throbbing and aching, coming back together. The skin stretched out between them like webbing, the anchors that bound pulling the flesh tighter together. With the skin connecting them, it wasn't long before all the lower digits of the hitchhiker's feet disappeared . His toenails grew dark and soft, spreading outward, claiming more of the space for itself. Before long the keratin coating was darkening and hardening, hooves kicking the back of the cabin.

"Oh fuck, kid. Yer ass is incredible. So fuckin' tight and hot." Rex grunted out as his cocks throbbed and stiffened inside Riley, "And yer a fuckin' good lookin' demon, just like I knew ya would be. And--fuuuck--you're horns are finally comin' in!" The trucker took a second and gazed up at the young demon's forehead, watching as two bulges grew against the beautiful red skin. At first the skin just looked irritated, but as two drops of deep red blood leaked out, two sharp black nubs emerged.

Riley gasped and sputtered, hot precum and then semen spraying across the trucker's large belly. The horns pushed out from his forehead before arching straight up, rising like tines of a pitch fork before him. It was the sort of array that a demon could get away wearing a backwards baseball cap with if he so choose. From the horns to the beard, the pointed ears to the fang, or the tail to the hooves, it was clear that Riley's innocence had been eroded. He was a furry, hairy, masculine predator looking for the next sexual conquest of immediate gratification he could manage.

"Mmm... ya look great, kid. But there's jus' one last thing we gotta take care of." Rex said as he slowed his thrusts into Riley's ass, letting his cocks rest against the nub of the kid's enlarged prostate, feeling him squirm with pleasure beneath him. He looked down at the handsome, massive demon propped up on his dashboard, taking in his incredible features and knowing the his boss would be very pleased with his work.

Leaning forward, Rex finally allowed himself to grasp Riley's thick, leaking member. The skin was hot enough to melt steel, but to the trucker, it felt simply incredible as he held it in his hand. "Ya ready, kid? Ready to know what a real demon feels like? Ain't no going back after this. And really, why would you want to?" he said with a wide grin, fingers gripping the human member tightly as his thumb swiped over the tip, smearing the clear precum over the head.

"Take me... Make me yours! I don't want to go back!" Riley howled, his voice dropping deeper and deeper with each moan.

Flashing a wild, sinful smile, Rex slammed his hips against Riley's ass, driving his two cocks hard into the the other demon. His pace quickened as he gripped onto Riley's thick thighs, lewd, wet sounds mingling with deep growls of pleasure as Rex's furred balls slapped against the younger demon's still human ones, although they wouldn't be human much longer from what the demonic trucker could see and feel.

"Goddamn, kid--nghh!--yer gonna make one helluva demon. Just let all that evil inside ya, feel it corruptin' yer body. Let my--oh fuck!--let my sin fill ya up." Rex said between thrusts, his big demon balls starting to tense and churn with his thick, hellish seed. Riley tried to speak but all that came out were grunts and roars. Clawed fingers latched onto the trucker's nipples, tugging and twisting them in a supreme act of flexibility even as he was fucked into the dashboard. Riley was panting hard, his thick chest rising and falling, his heart pounding. The cabin was full of the smell of sweat and musk in overpowering degrees.

Rex let out a deep, pleasure-filled growl as he felt Riley tugging on his large, pert nipples, loving the sensation of the young demon's clawed hands pulling on the leaking tips. He reciprocated in kind, one hand gripping hard onto Riley's pulsing cock as the other reached up and gripped one of the young demon's massive horns, yanking hard and pulling their faces together in a passionate, fiery kiss. Still thrusting hard, Rex pumped himself closer and closer to the edge, feeling his plump balls tighten in his sheath and his neared his orgasm.

The young demon was unable to hold back. His tail tightened, his balls tugged up and his cock pulsed before it unleashed wave after furious wave of orgasm. Jets of sperm splattered all over as the air practically oiled off of Riley's crimson skin. The orgasm reached his ass and his muscles fluttered around the twin, internal shafts. With that moment of bliss, however, something else had started inside of the young demon.

As the pearly cum spraying from his shaft turned yellow and then darker, it rained down on his hard, erect shaft. The flesh had already turned a bright red from blood and heat and demon flesh, but it began to sizzle and plump, bloating wider and taller, thickening dramatically before two gullies appeared. As the flesh along the top and bottom sunk in, the urethra at the head of the shaft began to split and migrate, pulling to the sides. The shaft wriggled and pulsed with an irregular heartbeat until all at once it split, two brand new demon cocks waggling as they gushed forth with satanic spooge.

At the sight of the newly made demon's dual shafts pulsing and shooting syrupy, demonic seed out of their tips, Rex couldn't hold himself back any longer. He thrust once, twice, and then exploded into Riley's waiting ass, his thick, yellow cum coursing with sin as it flooded into the the demon's hole. Rex's tail twisted and whipped behind him as his ass clenched with every thrust into Riley. The trucker's claws tightened along the thick, hairy thighs of the demon on his dashboard, and his pulsing cocks continued to shoot his hot, hellish seed into the handsome demon, coating his insides with sinful energy as it corrupted him completely.

Riley howled and bucked against the orgasmic cocks inside him, but as his guts and stomach were pumped full, his fit and firm stomach slowly softened. The definition disappeared and an ever so slight roundness now matched his plump pectorals. He grunted and took it all in, the last drops of seed released from his dual dicks. He laid where he was, basking in it all, a satiated grin covering his fanged lips while his tail swished languidly. His old life had been expunged, and a brand new one had been forged from fire and sweat.

As his orgasm began to subside, Rex slowed his thrusting hips and pulled his head back from the steaming kiss he'd been giving Riley as they fucked. Breathing deeply and catching his breath, Rex looked down at what his work had given him: Riley was no longer the young, fit human he'd picked up on the side of the road. Now, he was so much more. The demon impaled on his thick cocks was incredible, his thick body plump with muscles and fat and utterly covered in dark, sexy hair. Crimson skin shone brightly as blood-red dawn streamed sunlight in from the windows of the cab, glinting off of the thick strands of yellow demon cum that had landed on Riley's furry chest.

Rex reached down and drug his hand along the cum-matted hair of the demon in front of him, collecting as much of the hellish spooge as he could before bringing his fingers to his mouth and licking it clean, his long tongue digging for more of the delicious release.

"Mmm goddamn, kid. Ya taste fuckin' amazing." Rex said with a grin before he leaned forward and thrust his tongue into Riley's maw, letting him taste his own essence as the trucker lightly thrusted his half hard cocks into his cum-filled ass. The massive truck continued to barrel down the flat, desolate highway towards it's destination, kept steady by the hellish energies that had created it, while the driver and his passenger continued to pleasure each other, both of them enjoying Riley's new, sex, utterly demonic form.

---

While air brakes were generally prohibited within city limits, a deep and hearty hiss sounded from the truck as it came down the last of the hill, pushing into the city limits. While the reality veil kept its true appearance hidden from those the truck rumbled by, its full demonic glory was visible to any that had embraced the darkness within. The front grill stretched out like a metallic cow catcher on a train, the exhaust pipes curved up into wicked spikes like massive horns and the intricate metal work along the back flowed in intricate curves like flames frozen in place. The metal was all a coppery red and the bulk of the truck a menacing black.

Riley sat against the passenger side door of the truck, a beefy, hairy red arm hanging out as black claws drummed on the side of the truck. His rotund belly was barely clad in a white, stretched out t-shirt and a plaid vest. His long, burly black beard obscured his ample pecs and a backwards trucker cap sat on his head, two huge, thick horns jutting forward and up like guard rails. His dark eyes peered out of the truck as it entered city limits, watching the strange effect their presence had on the city.

Each street they drove down seemed to take on a bit of a different atmosphere; paint started to fade and crack, weeds sprouted and grew up thicker, dogs started to bark and howl, and the taint even reached the pedestrians. Riley was looking up ahead at an innocent enough looking teenager on a street corner. With the truck rumbling closer, his blond hair got greasy and longer and a blond mustache appeared above his lip. His smile turned a bit more sinister as a tent appeared in his shorts. All that change from just driving past the young man.

"Rex, what could we really do with all this stuff?" he asked, turning to face the driver.

The demon trucker flashed a fang-filled grin over to his newly transformed partner as he shifted excitedly in his seat, moving his left hoof to press against the clutch as he downshifted and began to turn the wheel of the hellish truck, following the road leading through the city.

"We can do a whole lotta bad, kid. A hell of a lotta bad." Rex replied with a wink as he glanced over at his new, sexy demonic friend. The kid had turned out so perfectly and having someone else along to help deliver the payload was turning out to be the best thing that had happened to him since taking this job. The burly trucker laughed loudly to himself as he pulled the truck around a wide bend in the road, tapping the brakes lightly as the truck rolled up to an intersection and stopped at the glaring red light. He leaned over to Riley and pointed out the wide windshield towards a low slung building a few blocks ahead of them.

"That's where we're headed, kid." he said with a sinister smile playing across his lips, "It's one of our demonic depositories, but I jus' call 'em Demon Depots. We got a tank fulla pure, liquid sin that's gonna be spread across the city. Once we empty out the tank, well, that sin'll work its magic and start corruptin' everyone and everything around us."

To any human not blessed with demonic sight, the nondescript building didn't seem to stand out at all. But to Rex and Riley, it was a sight to behold: A gleaming, obsidian marvel that was practically dripping with a demonic aesthetic. Much like their big rig, the building looked like it had risen up out of Hell itself, with shafts of deep red color spread almost organically over its walls, and massive spikes and curved metallic flames running along the top of it's harshly sloped roof. Thick, black smoke was belching out of an incredible number of chrome pipes that rose up over the building in stacks, polluting and corrupting the air of the city at a constant pace.

Sure enough, the neighborhoods around the building were the roughest and toughest. People were looking after one another with lecherous glances, there was the glint of blades and guns in the hands of those wandering around. The entire area seemed darker, dingier, and yet in that darkness there was a heat that clung to Riley, that made him feel truly alive and part of something bigger.

The truck slowed, rolling up to the gates around the facility. Somewhere in the back of his mind Riley could see the human guise of barbed wire and plain chain link, but the gate before him was massive - wrought iron, gilded spikes, metal serpents coiled around spokes and spikes. They looked like the true gates of hell. The ground shook slightly as a three headed canine-human hybrid security guard approached, each chin possessing a dangling, braided goatee strap. The hellhound guard snorted against the window, the glass fogging up a bit.

"Security pass." The middle head barked. As if sensing the need, the truck spat out a plastic card with Rex's demonic photo and unintelligible writing sprawled across it, except for his name. Suddenly Riley panicked, looking at Rex, wondering if he needed one as well. The truck seemed to respond by spitting out another card. It stuck halfway out, showing his photo, cut off right before where Riley's name would have been printed.

Rex arched an eyebrow and nodded his head at the card coming out of the slot in the dashboard, "Seems like yer gonna need a new name, Riley. Gotta say, it don't really fit the new you if ya ask me. Why not somethin' a bit more...sinister? Jus' pick what feels right and say it out loud. The truck'll do the rest."

Riley leaned back and looked at his reflection. His mousey, vagabond self was gone. He had his youth, but he also had enough masculinity to milk out and fill a forty liter bottle with. His huge beard, horns, fangs, and double cocks? He was a man's man. Riley reached out and took a hold of the edge of the card, his mind reeling through the possibilities before a small, fang filled grin crossed his lips.

"Orias..." He said softly. The card spat the rest of the way out, emblazoned with the new name that glowed bright red for a second before cooling to black. The newly minted demon grinned, offering the driver his card, feeling his hot semen start dripping down his legs again.

Rex smiled at the new demon's choice of name as he grabbed his ID card and handed both of them to the multi-headed hellhound guard. His twin cocks were already throbbing with need as the smell of Orias' demonic spunk began to fill the cab of the truck, the temperature rising steadily around them.

The three headed security guard looked the cards over, tracing clawed fingers across the emblazoned lettering as he read. Satisfied that the two massive demons sitting in the sin-filled big rig were here legally (even Hell had security procedures), the cerberus handed the cards back to Rex and reached down to his crotch, adjusting his own growing arousal as the smell of the sexy demons flooded out of the open window and filled his sensitive nose.

"Maybe see you next time!" Orias called over as the window was rolled up and the truck began moving in deeper to the demonic lair. It seemed even the Highway to Hell had its pit stops.
