Underdog
The small secluded town of Lowland Heights is struck with a demonic problem when a local woman tries to summon a hellhound for some extremely kinky fun. Now the entire town is threatened- death to those who are stupid enough to fight and a costly pleasure for those who go along with it.
(Mx4, FtHx1, various canine forms- werewolf, dire wolf, hellhound, dog)
Lawrence was called to the scene of a crime in the small town of Lowland Hights. It was a beautiful but small town hidden away in its own nook, and he had to travel quite some distance from the next closest city to be here. In a long duster coat, the popped collar and rim of his black hat almost hid his face. He was an arcane hunter- he specialized in hunting beasts and races of a more magical nature. See, the problem with this crime scene is that no one knew what the crime was exactly.
Lawrence examined the house of Lesley, a woman who had gone missing a short while ago. Most of the furniture was scorched or reduced completely to char inside the house. They found a large black dog but no sign of Lesley. Because of the scene they jumped to the conclusion of werewolf quickly... except, its just a large dog, its not a wolf. They also exposed it to silver to absolutely no effect. There was several types of supernatural dogs as well but this exhibited none of their behavior, it just seemed like a regular animal. There was what looked like paw prints and claw marks scorched into the floor in several places, but it could not have been this dog- the size of the prints was gargantuan. Lawrence noted several charred remains of books, grains of salt scattered about, a piece of used chalk and some wax remnants. Items of arcane nature- like those used in a summoning ritual. But this dog was not what was summoned... which means whatever it was is running around on the loose right now.
He had the roads cut off leading in and out of the town, since it was a crossroads for several locations, and he did not want whatever escaped from this house to vanish into traffic. Lowland Hights was built on what used to be an island in a lake. The lake had almost entirely dried up long ago however and a vast, thick forest grew in the giant round depression it once sat in. There was only one road leading north where Lawrence had come from himself, but to the south five roads converged. From the south several travelers arrived in town- they were within proximity to the town when Lawrence closed the roads off, trapping them in the area, forcing them to come into the town proper to stay while the roadblocks were up. Lawrence ordered the towns police to question all the people who were forced into the town, but they arrived at different times and scattered to find rooms to stay in for the time being, so it took some time to track them. It was a good thing Lawrence was present when they questioned a behemoth of a man, calling himself Kurst. With dark tan skin, muscular arms almost as big around as some of the other men's torsos and standing nearly eight feet tall- he was hard to miss. Lawrence would have almost considered not questioning him because it seemed like too obvious a form for a demon to disguise himself in. When questioned, the man had very few words in his thunderously low voice, and while he made up a story about passing through, as soon as they started to ask him more detailed questions like where he had been or if he had any proof he quickly stumbled on his words and instead resorted to violence. Kurst picked one officer up by the face and tossed him like a rag doll through the air. Two shot him with their flintlock pistols to almost no effect at all. The holes were glowing orange at the edges like super heated metal, and closed up and healed in a matter of moments. Lawrence quickly stepped in with his blessed sword and while he was still unable to inflict lasting wounds, he did hurt Kurst enough for the officers to restrain him in chains and take to the dungeon below the station where the long term prisoners were tossed to rot. Lawrence would interrogate him and try to reverse the ritual to send him back, but he was not entirely convinced he was working alone. Kurst spoke using very few words and was quick to give up trying to lie his way out of it- he did not seem the type to bother trying to disguise himself in the first place. Which means someone told him to hide. Lawrence left him in the dungeons and resumed investigating more people who were trapped in the town, seeing if he could pick up any more leads.
A lanky pale skinned man walked up to an officer at the station, looking unusually calm for the state of the town. "Excuse me, I think my friend is being held here? I need to speak with him."
The officer cocked an eyebrow. "Who are you, and who is your friend?"
The officer's eyes scanned the man over. His hair looked greasy and hung to his shoulders perfectly straight. He did not look the least bit like a threat- there didn't seem to be a visible muscle anywhere on his body. His eyes were a pale green in color and his clothes looked ratty and haphazardly put on. He was also not very tall, a shade over five feet maybe. What caused the officer to hover a hand over the pistol at his belt however was the number 6 burned into the man's pale flesh at the base of his throat in the front. Kurst had the exact same scar.
"My name's uh... Dwight. My pal's a big guy..." He put his hand way over his head and stood on his tip-toes. "About yey high."
The officer quickly drew his pistol, but just as fast Dwight thrust his own arm up and speared the officer's! The man's fingers were now tipped with pitch black claws nearly six inches long each and only slightly curved. The speed of which he had to grow them out caused the skin to tear around them, so he was also bleeding from the base of each claw. He brought his face uncomfortably close as the officer was forced to drop his weapon. "Just kidding. My name's actually Blight."
The nails on his other hand grew to match the other ones, thickening and then extending out, creating much less blood because they grew slower- but still bleeding a little. His skin started to turn grey at the base of the claws, and the darkness faded in deeper as it spread up his limbs. His toenails transformed into claws too but of a completely different sort. As much as the nails thickened they also narrowed, and they grew out while remaining bunted at the ends, making them terrible for scratching anything. His feet started to stretch out, causing his ankle to rise up out of his shoes. His big toe started to shrink both in size and complexity- the number of bones reduced rendering it a immobile, useless digit. It did not stretch with the rest of his foot, causing it to ride higher on his legs, so it no longer even touched the ground. His other toes however bulked up tremendously, evening themselves out in size and becoming fat and round. The extra skin on the bottom puffed out thicker and turned black even faster than the rest of his skin, and the same happened to the ball of his foot- creating pads. Because his feet changed so drastically in structure, his shoes were basically useless and he slipped his new paws out without even having to undo the laces. The thick pads of skin on the bottom of the paws protected them from harm while walking without footwear. The darkness spread up to his torso now, starting to turn the skin there grey as well, and where it had started at his claws was now turning completely black and sprouting equally dark fur.
His teeth started to narrow and sharpen at the same time, causing his gums to be forcefully shifted around, bleeding as a result. In the gaps created new fangs grew in, at first because of how the change happened his fangs were all horrendously crooked, jutting in several directions. Once it finished they were... mostly straight. Still more grew in at the back though, running out of space on his jaws, forcing both top and bottom jaw to stretch out with sickening high pitched snaps- this also caused his skull to stretch more narrow, but not as drastically. The darkness and fur spread up consuming his limbs and wrapping up around his torso. When the fur from both his legs converged at his butt, his tailbone let out several wet sounding pops and extended into a tail that quickly erupted in fur. In his pants his foreskin thickened as it turned black. It grew a bit longer and much thicker, and then developed a light coating of fur as well. Aroused by the smell of blood and rush of power he had over the human, his changing dick started to fill with his own blood. It fattened up inside the foreskin before extending any, giving the head an almost flat shape- making it almost a cylinder, but when it started to lengthen the urethra grew first, stretching out away from the shaft giving the head a point. As it stretched farther out from the foreskin the pale flesh tone started to redden, and hundreds of extremely small veins became visible on the surface as it stretched, with a few larger veins toward the surface that bulged out a bit. His foreskin had become a sheath.
Blight's face finished stretching out into a long narrow muzzle, much like a wolf but a bit longer and more narrow than a normal wolf. Blood from his teeth changing to fangs matted the fur on his jaw and neck. His ears turned pointed as they stretched upward to the top-sides of his head as his skin was stretched in several directions to accommodate all the changes. Like his face, his ears were longer and more narrow than a normal wolf and stood perfectly erect, straight up. The pupils in his toxic green iris stretched into tall narrow slits. He had transformed into a werewolf! He was not a standard werewolf though- the officer's pistol was loaded with a silver bullet. Even though the gun fell to the ground, the proximity to silver would still affect Blight if he was a normal werewolf. Worse still- the veins in the officer's arms started to throb and fatten up, the blood inside turning black. The swelling spread further into his body from the wound, but Blight did not release his grip, the officer could not break free! Blight just chuckled and drooled a bit from his maw, getting off on watching the man suffer. His breath was the acrid smell of sulfur.
Blood spattered against the window of the nearby tavern as other officers attempted to rush Blight, only to meet a much quicker and sudden end. The tavern owner barred the door and got several patrons to help him shove several barrels up against the door as well to barricade it from the chaos outside. All the patrons moved to the half of the tavern furthest from the windows. The windows were made of textured, colored glass so they were not great for looking at what is happening outside, but they could guess from the screams and blood.
One of the patrons named Juan found himself luckier than the rest when a cute woman clung to him in fear. "Oooh, save meeee."
She was only about five feet even, and slightly pudgy in build. She wore a knee length skirt and simple leather shoes. Her top was long in the sleeves and the collar was wide enough that it hung off one of her shoulders. Her breasts were each the size of her head, and he could tell by the way they wobbled about in her top that she must not be wearing a bra. She had black hair to her mid back that was violently wavy and left rather wild.
"N-now miss, don't you worry a thing, no one is getting through that door. Those barrels are full- there must be damn near eight hundred pounds pushed up against the door, plus the sturdy wood bar across it and the steel lock besides."
He pat her head and she took her head off his chest to look him in the eyes. He failed to realize her iron grey iris were unnatural- or that the number 6 was scarred into the bottom of her throat.
She blushed a bit. "I feel so... flustered. I- I heard when your life is endangered sometimes you'll feel aroused. A need to procreate while you still can or somethin' like that..."
He cocked an eyebrow, glancing at everyone around them, but everyone else was preoccupied staring at the windows in fear. "Y-you mean your horny? Hell of a time for that, ain'tit?"
She sat up a bit straighter, putting her face closer to his but also pressing her tits into his chest. "I know~ such a strange feeling. I haven't had the vapors like this'n ages... I... don't suppose you feel the same...?" Her lips hovered dangerously close to his, he could feel the heat off them.
"I-I-I don't even... know your name."
She brushed her hand up his crotch feeling the bulge inside. "My friends call me Hex."
She gently took his hand in her tiny hands and got up, pulling him along and they slipped into the back area of the tavern and then down into the basement where the huge wine casks were held. Once away from everyone else Juan tossed caution to the wind and pounced his chance to fuck a beautiful stranger. He pulled her skirt down and found she wore nothing below. Her labia puffed up and blushed brightly already, moist in arousal like she had promised. He laid her out on the stone floor and quickly pulled his pants down enough to fuck her, not wasting a moment. Juan did not notice as he fucked her, her gasps of pleasure sounded like breathy 'arfs'. Her nails on both hands and feet started to darken, black bled into them from her fingers out and as it did, they pulled narrower and thickened in turn. They slowly turned to blunted claws and her already pudgy digits started to swell up as they shortened a bit. Her nostrils tightened a bit as the end of her nose started to darken to grey. Hex's tailbone and ears started to grow longer at the same time, causing her to moan more sharply in pleasure from the feeling of her body stretching out at those points. Juan mistook her cries of pleasure as his own expertise at pounding her and thrust faster. Her labia started to turn grey as well now, and got still puffier. Her teeth sharpened but remained mostly the same in structure. As her hands and feet nearly finished their advance into paws, fur started to grow around her claws and then spread up her limbs quickly.
Juan felt a throbbing in his dick, harder than normal and oddly confined to the base. He started to thrust faster into her, which was also unusual for him but for some reason felt so right. As he approached orgasm the throbbing in the base of his dick became incredibly intense but he was too focused on reaching peak to stop and look. The veins felt like they were pounding dangerously tight and the base of his dick actually started to swell up. At first it just looked like a bit of a bump, but then it swelled further and further, forming a bulb at the base of his cock as he finally came into Hex. She literally howled in pleasure and fur erupted out covering her now canine ears and tail, and finished its advance up her arms and legs to her elbows and knees and stopped there. The final growth in her ears made them too large to hold themselves up and they flopped down- the fur on them much longer than anywhere else, causing her ears to blend in with her hair quite well. Her labia inflated even more, causing the shape of her pussy to distort into a more triangular shape as it projected off of her a bit in how pillowy it has become- a glossy black canine vulva. Pulling the lower point of the triangle out though, a long red thorn of a clit emerged and as Juan thrust into her, it shook up and down violently, which only stimulated it more. It bulged thicker and a bit longer and her pussy stretched open a bit at the lowest point, held open by a small knot formed at the base of what was now a small dog penis! The knot was about the size of two marbles- and about as hard as them too. Hex is a hermaphrodite. Juan had been bracing himself with his hands on her tits under her shirt, but as he pulled back in surprise at her appearance he felt several other stiff rubs as his hands retreated! She had three more sets of nipples down her torso under her clothing, all very erect. The end of her nose had also fully turned cool and black, and her lips were glossy black as well.
"Oh Gods, what the hell happened to you?!" He pulled his dick out in surprise.
Hex looked at her front paws and down at herself, feigning ignorance. "Aaah! Did you do this?!"
"No! How the hell would I do something like that?!"
Hex pointed at his bobbing cock, and the stone-hard orb in its base. "You changed to, a little!"
"AH! It must have something to do with that nightmare hound out there! W-what do we do?!"
Hex hummed in thought. "Nothing, I guess. I dun' know a lick of magic. Fixing this is a job fer that arcane hunter." Her eyes glazed over a bit. "Ooh, damn creatures made me look a freak. No one will want me now..."
"N-no, you still look adorable! They will find a way to fix us. You still look great."
"Y-you're just saying that to make me feel better."
"No, I really do think you look cute, even still."
"Then... why did you stop~?"
He looked down a bit confused at his dick and sure enough it was still extremely erect. Well, there wasn't a damn thing they could do to fix this themselves, so he might as well enjoy more sex with Hex. They would have to wait for Lawrence to help them with their magical problem. Hex went onto all four paws to let him pound her in that position now, so he would not see the devilish grin on her face as her pupils narrowed into slits.
Blight reached the basement and slid his long narrow claws into the keyhole to pick the lock, taking embarrassingly little effort to open it. Once inside the walked over to the prison cell Kurst was in. Blight was an especially small man, and Kurst was especially big- compared to Kurst, Blight looked like a toy. Blight leaned on the bars, glaring at his very large friend. Rust started to rapidly spread across the iron bars from where Blight touched them.
"You couldn't have tried just a liiiiittle fucking harder than that, to not get caught?"
Kurst just grunt in reply. They had shackles on his wrists, leading two chains into one that in turn connected to the wall behind him so he could only walk halfway across his already small cell. His hair was very short and bristly, and his eyes a ghostly pale blue, like ice, and his pupils already narrow slits. Blight slipped a bit, sending a cloud of rust into the cell then placing his hands directly on the bars and shoving inward, crumbling them. The rust devoured the iron to the point where the bars just turned to dust. Blight stepped into the cell with his hands on his hips.
Kurst sighed. "Getting bored."
With a swift jerk of his arms, the chains yanked taught and tore several bricks out of the wall they were attached to, freeing himself with virtually no effort. He could have walked out of the dungeon whenever he wanted- he was deliberately waiting for someone else to come get him. He flexed his muscles shattering the shackles off of him and causing his shirt sleeves to burst, and a rip to open his collar further down his chest. Blight chuckled and collected the chain, walking up to Kurst to look up at his face, over the huge pectoral muscles stretching his shirt out.
"Hey, Kurst?"
"Hmmm?" The behemoth bend down to put their faces closer together.
Blight quickly tossed the chain around his throat and yanked it tight. "Don't fucking waste my time."
Blight yanked him further forward, choking his neck with the chain causing the giant to stumble forward. Blight shoved him back and made him fall over onto his back completely. Blight quickly jumped up onto his huge body as it started to change and Kurst growled at him- though his voice is so low it sounded like an earthquake. A tail started to quickly grow out over Kurst's jeans. His foreskin fattened up and completely buried his dick as it started to change into a sheath. Nails on his hands and feet started to turn into blunt canine claws, and his teeth turned to fangs. Blight's dick was still out from enjoying making the humans suffer, and he speared Kurst's jeans with his claws and yanked them off to admire the giant package. As one could expect from such a large man, his dick and balls were considerably bigger than Blight's. Kurst put a transforming foot on Blight's chest to kick him off but he held on. When the semi-paw slid off his blunt claws scratched Blight across his side. Blight squirmed and grinned at the pain, yanking the chain around Kurst's throat even tighter. Kurst's face turned red and the veins in his throat bulged huge trying to feed oxygen to his brain. Blight was quick to shred his own clothing off with his claws, not bothering to take them off conventionally.
Blight slid between his legs and thrust his dick into Kurst who rumbled a moan, and his still changing dick started to emerge from his new sheath. The human head flattening as the shaft bloated thicker and reddened. The tip was stretched to a point by the stiff urethra. Fur started to sprout from his forearms, where his pubes used to be, his shins, and his chest. What had been human body hair reduced in length and thickened in density to turn into fur. His hairline started to advance down his chin, giving him large sideburns. He grit his teeth as his jaw started to creak and pop and grow out, stretching his face as the end of his nose darkened and slowly started to level off with his upper lip. His rib cage started to grow a bit longer, causing his torso to have a more barrel shape as the fur spread rapidly to cover it. Blight started to thrust more aggressively, though in doing so loosened the chain as his concentration shifted a bit. His crotch bumped Kurst's huge black balls and caused them to bounce up and down lightly with each thrust, and the long rigid shaft wobbled violently. A bulge grew in Blight's sheath in surges, getting harder and harder- he felt like he could feel every individual hard vein in it throb with pressure.
With his free hand he grabbed into Kurst's chest fur till the points of his claws touched skin and then with a grin, dug in and yanked downward, ripping four long red streaks down Kurst's body to make him bleed. The cuts started from under the shirt- quickly staining the white material with his blood. Blight flopped down, resting his face against Kurst's belly fur and rubbing the fresh blood on his face, taking deep breaths of the freshly exposed meat. The growing knot in Blight's sheath finally became too big for it to contain and it was forced out by pressure, yanking his shaft even longer and locking it at maximum stiffness. As soon as it was exposed, Blight used the chain to help yank himself forward and slam his knot into Kurst in one thrust, making him release a long rumbling groan in pleasure- the bulge of the knot was too large to be able to miss his prostate! Blight was no longer able to pull back really at all, so he could no longer thrust aggressively, forcing him to make rapid shallow thrusts instead, causing him to pant as his heart beat faster to keep up. He could feel a stiff bulge jamming against his chest- his fur was quite short compared to Kurst so it hid little sensations from him. His rapid heart rate beating against Kurst's groin was causing his knot to swell, jammed against Blight's chest. The slow rhythmic pulses of the knot and the quick hammering of a heart pressed against one another.
Slowly, deep sounding pops of shifting bone or the faint sound of stretching flesh and muscle could be heard from Kurst as his transformation slowed to a stop. Unlike Hex or Blight, Kurst turned into a regular looking black wolf. Except for the fact he is almost as big as a horse- a Dire Wolf. What had been his sideburns turned to large tufts of fur on either side of his head. The claw marks down his torso were already healed, and the fur grew back over the mended flesh. Kurst started to growl again in exertion, arching his back against the stone cell floor and then bucking himself up into Blight- grinding his rigid cock against Blight's chest, popping his massive knot out of his own sheath, locking him at maximum erection as well. Because of how huge Kurst was overall- his dick was as thick as a beer can and his knot was the size of a large apple! Finally Blight hit his peak and came, ramming himself into Kurst as hard as possible- his back paws made sickening grinding sounds against the stone floor as he used them to shove himself forward as hard as he could. He yanked back on the chain as hard as he could too- hard enough to pull Kurst's upper back up off the floor and trap the blood pressure in his head making his face feel bloated and hot, in addition to preventing him from breathing. The chain links ground together tightly and the chain actually shattered in half from the force just as Kurst climaxed and blasted Blight in the face from below. It was a good thing they regenerate quickly. Drops of cum hissed as they touched the floor- it was literally boiling hot, more than hot enough to badly scald any flesh it made contact with.
His orgasm took too much out of Blight, he only reared back from the pain of the scalding cum on his face before falling forward into the bushy fur of Kurst, and then falling through. He sank into the body of the much larger canine, falling forward unable to open his eyes or take a breath now. He was in an ocean of flesh, being massaged from every angle by soft, writhing meat. He could not only feel it caressing him though- he could also feel himself slide through it. He had sensations from both sides, and as he went deeper the confused nerves started to bridge themselves, and the two sensations blurred into one. Kurst groaned loudly and rolled onto all fours as Blight sank into him. It was as if his body were made of a dense putty. He felt his entire form being forced outward by the body sinking deeper in his, but by the time Blight was completely submerged, Kurst's body started to collapse in on his. Blight's form dissolved and manifested again as added strength in Kurst's body. His skin and muscle audibly groaned with strain as his body started to grow even bigger- slowly, as if having a hard time. In spite of being a full canine in form, his upper body and front legs started to bulge and swell with noticeable muscle! His neck swelled thick as he felt the veins in it hammering with pressure. His dick swelled a bit bigger as well as his balls, even as it softened and returned to its sheath. When Blight sank into him- he did not let go of the remnants of the chain however. He folded Kurst's tail into himself as he entered, causing the mass to be re-absorbed and used to add mass elsewhere, while the opening collapsed in on the chain. The chain then turned nightmare black down its length, and when it reached the tip the other bits of broken chain were drawn to it like a magnet, turning black and fusing with it to mend the break. What had formerly been the shackles around his wrists molded back together at the end of the chain as a large spade tip! The chain lashed around behind them as their new tail as Kurst's neck cracked loudly and was jerked to the side; Blight's head re-emerging beside it. He growled as pressure flooded his skull and his head and neck grew in size, till it matched Kurst's own.
Blight shook their body to force their fur to re-sort itself after the change. "No point in dividing and conquering if everyone knows who we are already, so might as well just return to our true form. Come on you big idiot, lets get out of this shit sty."
Kurst just grumbled in reply. He was no fool, and more than strong enough to have killed Blight if he wanted to during all that- but he didn't want to. Kurst enjoyed being knocked around by Blight, and Blight loved to inflict pain and rule over anyone he encountered, so they got along well... even if it didn't look like they got along at all. On their way out though, they seen the officer Blight first encountered, writhing on the floor with his clothes only half on- mostly fallen off. His veins filled with corruption and swelled till they pulled rock hard, and the darkness and stiffness spread. Filling his entire body and then seething out beyond his veins he groaned in pain as his body twisted and shifted violently against his will. He shrank and his bones jerked and popped out of alignment and back into new formations. He pant heavily, his body searing hot as it became encased in spreading fur, but he no longer had the ability to sweat so the heat just kept building and building. He was laying on his side, so his heavy breathing was easy to see. His dick drooled and sputtered cum weakly- he was not having an orgasm, his prostate was just overflowing; new canine sperm forcing out all human, so he could never produce human offspring.
"F-fuuuuck... hooo.... fuaAARK, aAAR- ARK! Oh G...gaard murrk urt strrRRRp, gahrk, wuh... WUFF!" He let out a long pitiful whine as his body finally stopped throbbing and twisting about- leaving him fully transformed into a black dog.
Blight shook his head. "They really let this place go to the dogs." Kurst let out a deep chuckle.
Juan kept fucking Hex in the basement of the tavern- luckily no one went down there. Everyone was too afraid of what was going out in the town to order many drinks. The stone floor was smeared with cum and sweat by now from several rounds, and still they went at it. Hex had fully transformed in their first round- her changes would advance no further than that. Juan however found the knot at the base of his dick swelled even larger as he approached his second orgasm- since his dick was buried in her, he did not notice his urethra projecting out more, stretching his penis into a more pointed shape. When he came, the rock hard form of the knot became more pronounced with its added size, making it more segmented looking. The primary artery that fed his cock blood ran down the back of the dick, creating a soft divot in the top of the knot to let it pass through without pinching it shut. His urethra did the same thing on the bottom of the knot, creating a divot there too- but the bottom one was less noticeable because his urethra itself bulged out in its place. He slowed to a stop after, but his dick was still stiff, and he was fixated on the large bulge. It felt really good to touch, but had not become so big till he had already climaxed. Since he was still hard, and Hex kept tickling his crotch with her tail teasingly, he decided to defy logic and go a third time in a row. He was so focused on the pleasure he did not notice he was growing his own tail slowly, and his nails had all turned to small claws as his teeth sharpened. The knot was very sensitive. Because being outside of the sheath it stretched the shaft to its absolute max; tugging the knot forward or back played on his pleasure nerves almost directly. Every time he bopped her pillowy labia with his knot it sent a small orgasmic surge into him, and his cock spit another gob of lube in reply. As he approached his third orgasm, he heard Hex giggle a bit for some reason. He started to thrust into her harder and faster and ram his knot into her fat labia harder and harder, till finally it slammed all the way through! He managed to cram the entire knot inside of her, and the pleasure immediately fired him over the edge into a third powerful orgasm!
His ears grew pointed and started to shift upward. His skull narrowed a bit as his jaws stretched his face forward more, his voice became more grumbly and animalistic. His tail grew in fully and the fur at the base started to advance up his back. His digits started to devolve on his hands and feet. Panting heavily, he went to pull out, but there was a tug. The knot was so large it was not easily moved. His leg and hip muscles trembled and the strength drained from his muscles in the presence of the tingling pleasure fired into him from her pussy tugging on the back of his knot. Hex wasn't letting him go soft, so his knot never shrank down. As soon as his muscles gave out from the pleasure he fell forward, which pushed his dick back into her, which put pressure on the front of his knot! His hips jerked back in response to the sharp pleasure from the front of his knot, but it caught on her labia again forcing him to involuntarily thrust back in, and out, and in. He was fucking her a fourth time, almost entirely out of involuntary reactions to what he felt! He stopped trying to pull out and just went with it, figuring he just needed to tire his dick out to pull free. Juan was unaware that Hex would not let his dick tire out- the knot wasn't going to soften. In fact, as he approached his fourth orgasm his knot swelled even BIGGER- ensuring he could never pull free, even if his free will suddenly got a second wind. He could not thrust into her fully since he was locked into her vulva, forcing him to thrust rapidly. Quick, wet slapping sounds echoed in the stone walled basement with her breathy 'ruff's of pleasure. Juan came again and again, seemingly more frantic and exasperated with each go, and more and more bestial he became. Whenever he tried to stop, or even just to rest the pleasure caused his body to take over on its own, so he could not stop fucking her dog pussy. And every hump rubbed a bit more of his humanity off on her vaginal walls.
Hex looked back as she heard everyone upstairs screaming, several windows breaking as people tried to escape as Kurst and Blight walked through the front doors- which were wooden. Their body gave off so much heat, just touching wood ignited it. And since the barricade barrels were full of alcohol- they blew half the ground floor up just getting inside. Everyone jumped out of the building real fast, the only one to stop and try to actually attack the hellhound was the bar keeper himself- and Kurst quickly ended him, spearing him through the chest with their spade tipped chain tail. Hex reluctantly put a back paw on Juan's shoulder, kicking him back while yanking herself forward to forcefully rip him out of her. It hurt his dick a bit and filled her with a sharp throbbing pain in the groin, but Hex was a glutton for punishment anyway. She just wished she had finished him off- Juan was still a bit human in the face and torso, he had one or two more orgasms to go before there was nothing left. Hex finally ditched her human clothes she was only half wearing at that point anyway and was going to slip out of the tavern. Unfortunately the celler doors were closed with a padlock she could not open. She groaned as she turned to see Kurst and Blight approaching, having come down the stairs for her. Their eyes were as brightly lit in the dark basement as they were upstairs, having a dim glow.
They ignored Juan, eyes immediately locking with Hex. "And where do you think you're going you little twat?"
Hex groaned. "C'mon, we barely ever seperaaaaate." She puffed her cheeks out in an exaggerated pout. "I wanna get my brains fucked out. I'm bored o' being the one on top..."
Hex moped as she slowly walked toward her other halves, but then grinned just as she reached them and bolted past! She was making a run for the stairs! The hellhound spun around and swept her legs out from under her using its long chain tail, then bit her tail and yanked her backward, sliding across the floor as they stepped over top of her. Hex tried to get up but either head bit a shoulder lightly to hold her in place as their massive dong emerged from the fat sheath again. They rammed the red rocket into her- her cry half in surprise and half in relief of being filled. They thrust aggressively, causing her to let out a huff with each thrust as it winded her slightly. Her own tiny dick flicked back and forth violently with each thrust as well, painting stripes under her on the floor with her salty lube- hot enough to steam. Kurst and Blight's dick was almost as big as Juan's knot had been, stretching her full easily. As they approached climax though they bowed their front legs, forcing Hex to do the same under their weight, putting her hips at an upward angle. She tried to squirm away knowing what was coming, but their fangs dug in harder, drawing a bit of a blood from both her shoulders. The hellhound shuffled their feet forward raising her butt as straight up and down as possible to brace it hard as they slammed their gargantuan knot down on her, crushing her labia against her torso. She whined and whimpered like a wounded mutt as they ground against her unrelentingly, finally stretching her wider as the knot started to jam itself in. She started to bleed a bit- the knot so giant that it was tearing her vaginal walls. Once it hit the halfway point, because of its rounded shape the rest burst into her in a fraction of a second, filling her well beyond maximum capacity. The end of the dick was wedge so far into her it felt like he was scratching the roof of her womb with it. Her legs started to go numb- her pussy so full that the nerves and blood flow was cut off to her lower body. He stopped mostly once they were in, letting their pleasure fade a bit. He thrust back and forth a few times, seconds apart to tease her. Each time he thrust in Hex seen stars as the giant dick in her was pressed in so hard that thrusting in actually shoved her blood pressure around- momentarily rushing her head when thrusting inward. When he pulled back, it felt like he was about to yank her organs out with him.
Kurst grunt. "Time to come home." Blight sneared. "And stop fucking around with squishy mortals."
They folded their legs under them, slamming down on Hex. Rather than squash her against the floor it was like someone smushing two chunks of putty together. The hellhound groaned as their ribs popped a bit, their torso getting even wider as the mass of another body was added to them. Bone spurs grew off each vertebrae, lancing their back as a long line of tiny spikes. Its front claws became sharp, thickening a bit more and growing even longer- they flexed their paws and raked lines through the stone floor. Their upper body and front legs got even more muscular, making the front half of their body a good bit larger than the rear. Even as their balls swelled larger and heavier, a powerful inward pressure exploded behind them and a bubble of soft smooth skin appeared. The bubble turned into a tiny doughnut, then a plush ring, then finally developed into a pillowy triangle as a canine vagina formed on the beast. The skin on the back of the scrotum trailed into the labia- as both were made of the same soft black skin. It arched its back from the feeling as pleasure tingled down their entire torso. Skin bunched up and pushed out, stiffening into eight nubby black nipples down their underside. Hex's head emerged on the left of Kurst, but she growled and groaned long and slow as the bones in her skull cracked and shifted. The veins in her neck bulged as her throat throbbed bigger and longer. Her face stretched out as fur advanced up her neck and over her head. Their hair started to change forms as well, becoming shorter and more dense to turn into fur- except Kurst whose hair was so short to begin with there was never really a difference in the first place. Blight's shoulder length hair became long bristly hair that stood up off the top of his head and neck a ways, making him look a bit bigger than he actually is. Hex's even longer hair became a bushy wild mane around her neck, especially off the underside- long licks of fur jutting every which way. Her demi-human head finally finished turning full feral and matching the size of the others. Blight was the savage right head, Kurst was the calm and quiet center head, and Hex is the lusty and playful left head. They are a cerberus- a three headed hellhound. The scar tissue at the base of their throats did not grow fur over it- burned into their flesh their numbers all lined up- 666.
They all groaned as their dick grew more, finally being restored to its proper glory. Even though they clearly already had a full erection, it felt exactly like getting another erection. A slow gentle pressure that brushed their pleasure nerves like a feather. The pleasure started to grow in intensity quickly however- the skin audibly stretched tight yanking on the nerves. The larger veins were squeezed tighter but bloated larger in defiance, looking deep purple against the gentle red of the shaft. As the larger veins spread they almost looked like worms snaking around under the skin, branching further. Their knot swelled larger and harder and larger again. The shaft bloated tremendously in the middle and spread over all of it- equaling the knot in girth at the middle! It started to swell more and more, becoming impossibly tight and starting to look like a gigantic football in shape. Pre started to fire from the head in short, repeated bursts with each powerful throb as the shaft groaned like twisting leather, trying to stretch even larger but unable to find any room left. The three of them trembled and their legs bowed as the pleasure took their strength away, they growled and whined at the agonizing pleasure. Their whimpers became sharper as they threw their heads back and their dick vibrated with internal pressure! It was too much, too fucking big! It couldn't possible take any more, they hit their limit, they were going to explode! In a loud wet sucking sound their shaft burst apart- yanking into three parts! It split all the way into the sheath, immediately yanking the poor overtaxed sheath as tight and wide as it could possibly allow as their one mutant cock divided into THREE huge canine dicks! Their huge wide knots jammed against one another fighting for space, forcing the two side cocks at an angle, almost forming a vague triangle between the knots. This also meant two of the shafts were sideways to allow them to fit. Their own rigid cocks rubbed against one another, pulsing hard with fat rope like purple veins. The explosion of their fused cock also fired them over the edge, and all three phallus burst with long rope like streams of thick cum that hissed loudly as it splattered on the floor, sending up a cloud of steam from the heat! Each pulse of cum lasted a full second with only a half second break between. The overall orgasm lasted a bit over half a minute before their giant wrecking balls were finally spent.
Juan seen Hex found a better mate and wandered out of the tavern- too horny and desperate to burry his bone to even feel rejected. He luckily found a large black dog quickly- Lesley. The original dog they had found at the investigation scene IS the missing woman. She summoned Hex, Kurst, and Blight, thinking she could control the demon and employ it for some kinky otherworldly sex. Their contract allowed her to survive the sex which otherwise would absolutely have been fatal. Not only would their cocks rip her torso apart- their cum would have given her second degree burns if it wasn't for the magical contract. She rode them while they were on their back, so she had one dick in her butt and two wedged impossibly tight into her pussy. The pact prevented them from harming her in any way- it did not prevent them from transforming her however. All their thrashing about during sex also scattered the salt circle so once they were done- there was no longer anything containing the demon from wandering off and doing whatever it wanted. Once she had a taste of their scalding spunk she became addicted, and like Juan after her- she couldn't help going back for more and more, dooming herself to be increasingly more canine as well. She ran over to Juan as soon as he approached, sniffing his dick bobbing out in the open and then quickly scooted around to present her rump! Juan did not need to be asked twice- he mounted her immediately and started to stuff that knot in. As he started to approach yet another orgasm his body gave off small cracks as his remaining human features started to fade into more dog. He seen another large black dog approaching from the police station- what used to be an officer. The three black dogs all looked at one another, and their pupils started to stretch into narrow slits, and they felt oddly compelled to join together.
