Darren knew that he should stop using the amulet, it was a cursed artefact that he had found while rooting through a curio store that had burned down years ago on a dare from his friend Roger, however it was just too addicting to lock away inside of a box. The small, white charm spoke to Darren in a way that no one, not even his boyfriend Kenny could understand. The first time he activated it's power he had been scared out of his wits. Who wouldn't have been? That was just how terrifying the dark power that rushed through him was at the time, but now, weeks later, he felt as though giving up the amulet would have been unthinkable.

Every time he put it on felt better than the last, to explain the sensations which rushed through him was difficult, but to say the least it felt like some part of him was waking up from the best sleep he had ever had. His senses all seemed to come alive whenever he activated the amulet, ramping up to the point where he could almost taste the wind with his long, slobbery tongue, while at the same time the strength which threaded itself through his engorged muscles proved to be just enough to allow him to lift scaffolding above his head. Never for very long though, he was still just a pup, after all. Adding to all of this was how much he loved his dark red and black fur as it raced all across his body, giving him a dense coat which could protect him from the coldest of rains and the harshest of winds. Darren honestly wished that he didn't have to change back some days, but he had to, if only because there would have been no place for him within the world looking as he did with his curled horns above his head and striking black muzzle, not to mention his fiery crimson eyes.

Oh well. 

One good thing that came from him returning to his human self was the fact that he didn't have to fight to control his tail whenever it grew from the base of his spine. The restless appendage always seemed to find a way to cause trouble for him, like when it had wrapped itself around Kenny's waist and refused to let him go the first time he had shown his best friend the power of his amulet. To say that the highschooler had been shocked would have been an understatement, especially given that Darren rose up above him about a foot above his own five foot eight height whenever he decided to 'put on his fur' as he liked to call his transformation, and yet after spending several nights stroking his very soft hand along the length of his muzzle on down to his bone covered collar the blonde haired boy had safely replaced his fear over possible being mauled to death the by monster in front of him - Darren had long since promised himself that he would never do such a thing - with innocent curiosity.

Having the fifteen year old brush him with a fur brush was something that always got Darren's leg twitching and his tail wagging a mile a minute. Sure, it might have been embarrassing to be seen being treated like a common mutt, but there was something in the way Kenny would dote on him that never seemed to bother Darren. Maybe it was in the way the other smelled? There did always seem to be this thick, musky scent that traveled around the older boy's body whenever they were together, yet Darren had no idea what could be causing Kenny to make such a scent. Nor did he understand why his sheath would always twitch whenever he breathed in the odor as it wafted along Kenny's groin. 

Some quiet instinct in the back of his head had whispered to Darren that Kenny was important to him and that this scent had a very special meaning, but the middle schooler was at a loss over exactly what this all meant. All he knew was that if Jeff kept bothering his packmate then he was going to hurt the other. Badly. He didn't like it when the bully of a teenager and his buddies heckled his shy bestie, nor did he care for the other putting his hands on him. The last time he had seen the other do so had set Darren's slightly pointed fangs on edge. Thankfully Jeff got the point to leave the blonde alone after he had literally growled at the other, but if the whispers he had been hearing from some of Kenny's other friends were true, then he was going to have to make a point to teach the bully a lesson about leaving his packmate alone.

Darren growled as he noticed that he was doing it again; thinking about Kenny as his packmate instead of his friend was something that bewildered the middle schooler the first time he had done it, and yet it was getting harder and harder to keep from doing as such. It just seemed right to consider the other as being a member of his pack. He was the alpha between them two of them, after all. Kenny was his to protect, and he wasn't going to let anything stop him from doing as such. This was probably due to the lingering effects that the amulet was having on him.

After taking off the amulet following a long night of wandering about the city and marking his territory with his scent mark, Darren had noticed that he had retained certain things from his transformation. His nails were now much longer and sharper than they should have been, despite constantly filing them down. His ears had become pointed at the tips, thankfully he could hide them behind his shaggy mane of hair, though only if he allowed himself to grow his locks out. One of his eyes were now a bit brighter than they should have been, luckily enough most people didn't stare at him for very long to notice anything out of place with this, yet Kenny had been the first to call out this strange fact. 

Kenny. 

Just thinking about his packmate...friend made him start panting in want. 

These days his youthful mind was almost always flooded with the thoughts of the older teenager; it would be nothing for Darren to be sitting around inside of his room and then all of sudden having the sense that something was wrong with the other. The thirteen year old would then get up and walk out from the apartment his sire and dame lived in to walk down the dirty city sidewalk across the train tracks into the suburbs to see the other. Most of the time he would call beforehand just to make sure that the highschooler wasn't busy with some of his other friends, but sometimes he would just walk on over without warning. During these times Kenny wouldn't know that he was around, as Darren would simply sit outside his window to look at the other through his bedroom window from the shadows of the trees in the surrounding forest. 

Sure, it was kinda creepy, but it was just so damn hard for him to stay away from the other, especially given that he would often find Kenny crying in his room, usually this was because his mother and father were having another shouting match with one another. The blonde was especially sensitive when it came to emotional trauma, and nothing made him more upset than the older pair screaming and tossing items at one another for minutes on end. Thankfully this would be remedied by the two of them spending all summer with each other, as Darren was about to graduate from his middle school and enter into the high school that his packmate was studying at. He was most certainly going to enjoy wrestling with the other on his bed, more than likely pinning the older boy down and then nipping at his neck and shoulders in order to cement his place as alpha between the two of them.

Just the thought of Kenny on his bed, his body glistening with sweat and his body giving off the strange musk that always emanated from his body, made Darren sheath and balls twitch in a spectacularly weird way. The feeling of his cock attempting to push out of his dark red sheath made the brown haired boy whimper and groan from where he stood inside of his bedroom. The fact that his penis had warped itself into the tapered red spear of flesh that it was now was something that had startled Darren to no end, yet after weeks of playing around and experimenting with his new package the middle schooler found himself enjoying the way everything felt down there now. Maybe it was due in part to how sensitive his body was thanks to having his member being packaged away all the time instead of flopping out as it once did, or perhaps it was due to all of the hormones which flooded throughout his body following his balls inflating in size. Darren wasn't sure, all he knew was that as he prepared to hit the precipice known as puberty many things inside of his body seemed to be changing in a way that he was sure wasn't normal. 

Yet it was hard to care about any of that. He was perfect the way he was, Kenny had said so, and his packmate would never lie to him. So it didn't matter that the tip of his tailbone had pushed out to give him a small little stub of a tail, nor did it matter that he often found himself growling at people whenever they pissed him off. As long as he didn't let things get out of control then none of that mattered. The only thing that was important was Kenny. 

His Kenny. 

He needed to go and see the other right now. He couldn't wait the five extra weeks that it would take for him to graduate from his boring ass middle school. He had to see his packmate right this second! Had to feel the blonde haired boy's breath on the nape of his neck. Had to have his lanky legs pressed up against his muscular waist. Had to feel his hands brushing over the fur of his face, stroking his nose and horns. 

With that thought firmly set inside of his mind, Darren grabbed his amulet from off of his desk and then looped the string he had threaded through the empty eye sockets around his neck. Rushing out of his house, the thirteen year old just managed to grab his keys before he darted down the stairs out into the world outside. Evening had colored the city a bright shade of red, the light from the waning sun almost seemed to caress the middle schooler's chest as he breathed in the filthy scent of the air around him. A quick snort removed much of the foul odor but it was barely enough to keep him from suffering the effects of living in such an unclean neighborhood. He shook his head. He was getting off track. He'd work to remark the area around the apartment with his scent once he got back, right now though he needed to make his way towards the local park. 

Getting to the tree filled landscape was easy enough, as there was barely anyone outside right then, given that it was Sunday evening and all. Sniffing the surrounding area he had settled himself in twice over just to be sure, Darren chuckled before pressing the amulet into his collarbone. A flash of red colored the sea of trees around him before he let out an audible gasp. In the seconds to follow the thirteen year old found himself awash with dark power, the likes of which made him grunt and groan as he felt the blood inside of his body thrum hard enough to make his veins rise up underneath his skin. His heart beat wildly underneath the blue shirt that he had thrown on today as the hairs all along his body pushed up to cover him in his dark red and black fur coat, not that Darren noticed as he blinked his heterochromatic eyes twice before clenching them shut and then riding out the twisted waves of pleasure which swam over his body.

The first things to change were always his insides, the organs which carried his vital fluids would swell in size, forcing his outer extremities to follow suit in order to contain their new girth. His bones tingled as they grew outwards, several small protrusions split themselves from out of the top of his skull, the back of his neck, and the flesh of his arms and ankles before growing wider and longer. That none of this hurt was something that always amazed Darren, as he was sure that biologically speaking he should have been a mess of blood and tissue, but he never was. The magic within the amulet always seemed to keep everything from falling apart as the bones on top of his head pushed out and then curled back, while the others wrapped themselves around the lower sections of his body in an almost protective manner. Drool dribbled from the sides of Darren's mouth as he snarled suddenly, the feeling of his teeth growing into fangs was something that was just too weird to fully describe, however he loved the sensation of the tips becoming long and pointer all the same. 

His crimson eyes blinked themselves open just in time for him to witness the front of his pale, furless face pushing forward to return his canine snout back to where it belonged. Darren's nose grew darker and darker until it finally became just as black as the fur which was racing down the length of his body; he snickered slightly as he imagined pushing his sniffer along the line of Kenny's butt. The thought of scaring the other by sneaking up behind him and then tackling him to the ground made a deep chuckle roll out from Darren's throat at the same time his fingers wiggled around almost playfully. His packmate was really in for a treat tonight, as Darren was almost bursting with energy right now, the likes of which demanded that he play rather rough with Kenny tonight.

Sadly, he wasn't going to be able to tell his bestie any of this, as the change back to his true form prevented him from speaking as he normally would, but that was fine with Darren as a price to pay for gaining the body that he deserved. Besides, he could vocalize himself in such a way that all of his thoughts and emotions were clearly able to be understood by those around him. He chuckled as he remembered how a snap of his teeth had stopped one of his other packmates from trying to tug on his tail, the overly playful pup had thought it cute at the time, but that was only because he had no idea how sensitive the appendage really was. Maybe somewhere down the road he could show the other how it felt after giving him his own tail, he was sure that his powers would grow enough by that time to the point where a strong bite could infuse another with the powers running through his darkening blood.

Popping his neck from side to side, Darren clenched his enlarging fingers into the thick, dark pads growing within his hand, the fact that his nails were becoming just as sharp and dangerous as his teeth made the middle schooler grunt in satisfaction. 

That was how it was supposed to be. 

He was a dangerous hellhound, after all, even if he were still a pup.

He needed his claws to rip apart others who might endanger either him, his pack, or his mate. But he also needed his muscles as well, because without those he was no better off than he was when he was in his human form. With that thought set into his mind, Darren flexed his arms several times over, willing the hidden strength within him to surge outward into his biceps and thighs. The sight of his black furred arms and legs plumping with extra muscles and tendons put a dark smile on the hellhound's face, he always did enjoy the pleasant burning sensation that came with his body bulking up as it did, though he would have to chase this feeling by working out in the gym at his high school whenever he wasn't wearing his fur. Darren yelped slightly as his balance was forced to shift, thanks in part to his willful tail fully sneaking its way down the length of his spine. Flipping his head around, the crimson eyed hellhound growled at the spade tipped appendage, however it merely waved back and forth at him almost as if in delight of his frustration. He soon gained full control over his new addition forcing it to snap at the air once before settling down across the widening cheeks of his rump. 

With that taken care of, Darren looked down to his arms to find that they were now much thicker than they had been just minutes prior. Flexing, the young hellhound watched as a large mound filled the expanse between his elbow and tricep. Darren snarled in joy as he thought about how much strength he now possessed. This was more than enough to protect Kenny from anyone or anything that might try and threaten him. Rolling an eye down to the lower half of his body Darren was unsurprised to find that his red furred chest had expanded outwards, the sight of his broad pecs and tightly packed abdomen made him subconsciously nod in approval. On further down he could see that his sheath and balls had become something to actually be proud of, he never liked the fact that his protective pouch was so puny in comparison to the massive girth that it was at that point in time, that was why he willed this part of himself to stay as it was supposed to be. Reaching down to fondle his balls, of which just barely fit into his paws, Darren lolled his much broader tongue out from in between his black lips as he thought about how much fun he was going to have making Kenny sniff and lick him down there. 

Chuckling once again, the hellhound stroked himself off just enough to encourage the tip of his much wider cock poking free from the tip of his sheath before he released his genitals. Stretching his arms upwards, Darren flexed his body for several seconds, working out the kinks which always seemed to stick within his body whenever he returned to wearing his fur. Once he was done the hellhound wiggled his toes, noticing as he did so that his formerly five clawed feet had become three full digits, the likes of which were tipped with deadly claws. Noting that his transformation had finally come to a halt, Darren rolled his warm, black nose across the fur of his body, kneeling on all fours in order to have a go at both his groin and back behind his butt underneath his tail, before hopping up and then looking about the park.

Night had fallen onto the city, completely shrouding everything within a jet black hue which was just barely broken apart by the yellowish light of the various streetlamps centered about the area. Seeing this, and failing to hear any pedestrians making their way towards him, Darren threw his head up to let out a low, bone chilling howl, the likes of which made several people shiver in their steps. After singing his praise for having returned to his true form, the hellhound lowered his head, tracked his position with the makeshift woods, and then darted off towards the south. Kenny was most definitely going to get a surprise tonight once he got his paws on his packmate tonight. 

A very big surprise if the pulsing in between his legs was anything to go by.
