On the first day of TFMas Kaevon gave to me,

A werewolf who is knotty!

It's December at last! The holiday season is finally here and the Christmas trees are going up. There are so many ways to celebrate, but nothing better to celebrate the reason for the season than a good old fashioned Advent Calendar. :iconLuke32: couldn't wait to get in on the fun, so they bought one the second they could! Though…were Advent Calendars supposed to have dog toys in them? Or…feel this warm?

If there was one tradition Trysten loved more than the others, it was buying that first advent calendar to ring in the holiday season. He closed the door to his apartment, unzipping his jacket while juggling the shopping bag around in his hands. There was a bright smile on his face, humming a gentle Christmas tune while hanging his jacket in the closet. Even if it was getting colder out, that didn't stop him from lounging around in his traditional tank top and shorts. His shoes were kicked off in the hallway as he practically hopped over to the couch, throwing the bag on the table, shifting forward, and letting out a soft sigh of delight.

“Alright, let us see what we have here!" The humming continued as he rooted around the bag, pulling out a few animal themed Christmas decorations for putting up later. Some garland, a plastic arctic fox, a few other knick knacks with clichés aplenty. This was one of the first years he was feeling comfortable going a bit more overboard with the decorations, so he bought more than enough to keep him happy throughout the season. But again, those were all just fun additions to the piece de resistance: the advent calendar! He even found one that directly appealed to his interests, hardly waiting a second as he pulled it out of the bag and ripped off the plastic covering. Turning it around and tossing the trash to the side, a strangely elaborate scene was painted on the cardboard-like front of the fun holiday candy keepsake.

There was an oddly detailed werewolf painted all across the twenty-five day calendar, small little flaps hiding some small treats for Trysten to enjoy every day of the month until Christmas. It was so hard to wait, but as he shifted around and adjusted himself on the couch, he eagerly set upon the first day to unveil his first surprise. It WAS December first, after all. “Why wait any longer? I believe the celebration should begin now!" He nodded to himself, rainbow mohawk bobbing lightly with each movement before he searched the calendar for the day one window. Now that Trysten was getting a closer look at the calendar, it was surprisingly large. The werewolf on the front was snarling, staring directly at the viewer with a goofy and comically small Santa hat on its head. Its claws were menacingly sharp and its clothing was torn and shredded all over, clearly a forced change as the setting seemed to be an apartment not too different from Trysten's. “Hm, that's quite the strange coincidence." Trysten mused to himself as he finally located the small flap labelled 'Day One.' It was a bit surprising how large it was…but that must've meant there was a large piece of chocolate in it! Without waiting a second longer, the flap covering the first prize was torn open as Trysten reached inside, grabbed the hidden object, and pulled out…

“...a tag?"

Between his fingers rested a small metal tag in the shape of a bone, colored a deep forest green with engraved moons highlighted in a deep, blood red. The confusion was pretty clear on Trysten's face, raising a brow as he turned it over in his hand and saw there were no other identifying details about it. “Is…this a dog tag?" He mused, flipping it around his fingers to get a closer look at it. There were no other noteworthy markings on it. No engraved name, no ring for a collar…just a Christmas colored thin metal bone. It certainly wasn't what Trysten was expecting, putting the tag down on the couch before turning the calendar around to get a closer look at it. There was literally no writing on the front …or the back, or the sides aside from the indications of the days. There was just a strange series of glyphs on the drawn fireplace that looked like the person who designed it had an obsession with things that looked like they were Celtic. “Could've sworn this was labelled as a chocolate calendar…" The thoughts flowed freely as he ignored the warmth of the holiday trinket. There was too much that confused him to notice such a small change. He reached back to scratch along the side of his head just behind an ear as he considered opening another day.

“No…though this is very odd, opening day two would be just…" The words trailed off as he felt a twitch just above his rear, biting down on his lip before letting out a gasp. His teeth felt awkwardly sharp…more so than usual. Trysten blinked a few times, his thoughts drifting around as he put the calendar down and turned his attention back to the tag. As he picked it up again, the metal was giving off a strange green glow. And it was warm…no, not warm. Hot. Bright. Intense. Irresistible. His mind immediately went to all the werewolf stories he'd read about before, thoughts racing as a smile twitched to the corners of his mouth. As he shifted around on the couch, he closed his hand around the tag and rumbled deep from the back of his throat. He remembered seeing something last year about lots of changes being triggered around the holidays. Could this be one? It was hard to focus on that as his chest itched, bringing his free hand to scratch under his tank top before he felt something different. Something rugged. Something…soft.

Like fur.

His eyes shot open, pulling at the collar of his tank top to look down at his chest as he saw a mottled mix of gray and black fur growing in. He could hardly contain the excitement, shifting around as he turned his head to look at the back of his shorts which were already straining from something pressing out of the base of his spine. Trysten took in a sharp breath, exhaling in a shiver as the heat transferred from the tag directly into his body. It flowed slowly at first…every beat of his heart bringing the heat further into his body before it focused in his chest and fanned out everywhere. His toes. His ears. His shoulders. His stomach. And above all else…between his legs. Trysten shivered again, harder this time as his need quickly made itself apparent. There was a familiar twitching under his shorts, making them feel tighter as his toes curled in his socks. “O-oh man…is it…happening??" He thought out loud, voice already getting deeper as his heart skipped a beat or two. Trysten wasted no more time as he shot up from the couch and took off toward the bathroom, stumbling from cramps in his feet before he threw open the door and looked into the mirror.

His face was already looking different, beard getting thicker and a slight tint of black dotting his nose before he curled his lips back to look at fangs slowly sharpening in his mouth. It was impossible to contain his excitement, back arching in a twinge of pain as Trysten let out a surprised yelp. It was a noise he'd never made before, but as his hips strained against his shorts and his arousal tented up in the front, the excitement continued to grow. He wanted to stay there and watch, revel in the changes as his breath picked up and one of his wildest dreams came true…but something in the back of his head shifted. Quite literally. His ears twitched as they pulled up into points, Trysten having to shut his eyes tight as the pressure along his forehead and jaw made him gasp with a moan.

Stumbling backwards out of the bathroom, Trysten held himself up against the wall with one hand keeping him balanced. His fingers curled inward, the paint underneath stripping as sharp, black claws were already growing out from his nails. He took no notice, though, only able to do everything he could to keep himself standing. The excitement had built and only fueled his need, chest heaving as he could feel the capacity of his lungs increasing dramatically. Every step he took back toward the main room felt awkward…unnatural. Too small. Whereas his shorts were just slightly strained before, now they were actively feeling tight. Cramped. Confining. And his need…oh, how quickly it had picked up. Trysten was practically throbbing in his pants, the angle in which that raging heat pressed up against his pants shifted around as he leaned his shoulder against the wall. He couldn't bear it, digging into his shorts as the button popped off and he grasped at himself with a long moan. It felt…different. Stiffer. Larger. With a strange ring of soft hair pressed close to his body. But he couldn't think about that now, only focusing on rubbing and stroking at himself before letting out a long whimper of a moan.

The pleasure was electric, addicting. It brought more of himself out from his body, the shape shifting around as he grasped and squeezed and stroked. But he couldn't focus on how good it felt, no. All he could think about was the itching. The tightness of his clothing. The cramping of his limbs. Something had to give as the excitement he felt began to shift. He pushed up onto the balls of his feet as his socks strained and ripped. The waistband of his shorts snapped and tugged as they threatened to burst. His voice was already at least two octaves deeper as he couldn't control his growling. And his thoughts…if his body was already feeling constricted, his thoughts were exponentially worse. There was a strange twinge, a pulling need that made the heat coursing through his body harder and harder to ignore. Coherent thoughts were fading away, unable to grasp what the sensation was other than…a call. An urge. A desperation. The thoughts he could still control were shifting to ones of worry, trying to reason through not just what was happening, but how he could manage with whatever was happening to his body. His clothes were already tearing. His underwear was soaked with his dripping need. And his growling…his thoughts…his focus. All of it made Trysten feel as if everything was quickly spiraling out of control. And with a loud ripping of fabric, a sudden gasp from the back of Trysten's throat? It was all out of his hands.

Trysten stumbled again as he fell to the floor, catching himself on all fours as he dropped the dog tag and curled his claws into the carpet. The tag was practically burning with a dancing green and red light, looking as hot as Trysten felt. A long, gray mottled tail tore through the seat of his pants and snapped the elastic of his jock clean in two. The shorts fell down along his legs as more jet black claws tore through the fronts of his socks, paws practically bursting out of them and quickly growing too large to be contained. More of that gray fur grew out from his legs, muscles expanding and growing while his joints shifted, grew, adjusted to a newer stance. Trysten gasped as he grit his teeth together with a growling moan before his back arched higher into the air. His body quickly expanded as it pulled the tank top apart to pieces even before the fur spread further along his body. His shoulders pulled back a touch, fingers gripping harder at the floor before the claws pulled up handfuls of the carpet with every twitch. And through all of the changes, through all of the confusion and excitement and worry…his need just got heavier and heavier.

It was impossible to ignore, jock having fallen down into the remnants of his pants as his length was turning a deep, dark crimson. It was throbbing in the air, practically glistening with his previously contained arousal before a long drip spilled out from the tapering head and dripped onto the floor. It swung around in the air as Trysten did his best to stand back up on two legs, jaw clenched tight as it continued to press further out into the air. His goatee stretched down his neck and along his face, quickly connecting in one continuous patch of ragged fur as the gray dotted all different parts of his body. His tank top, though barely hanging onto his body, was standing out in stark contrast to the rest of the mottled fur along his chest, down his sides, lining his waist. It looked two sizes smaller than it did just minutes prior, Trysten standing hunched over on two growing and monstrous looking legs before he grabbed the remnants of his tank top and tore it clean off with a snarl. His thoughts were somewhere in between his growing concern for managing his life and that raging need screaming at him to attend to that pulsing, irresistible need twitching between his legs.

His posture continued to shift, spine stretching out longer while his growing tail flicked and whipped around behind him. His ears pressed up further as even his mohawk shrank back and pressed against his head, once brightly diverse colors quickly overtaken by more gray. It grew in thick and long, lips shifting to a deep black as Trysten finally made it over to the main room. He bowled straight into the table, knocking it over as he fell down to the couch and immediately grasped at his shaft. A thick knot had grown at the base of his pushed back sheath, hands awkwardly stroking and rubbing at himself before his hips bucked in the air and found purchase in the couch. His whole body shook as he drooled with a pleasured whine, rolling his body into the cushions as the changes took over more and more and more. Every thrust against the couch was like another direct injection of adrenaline into his veins, fur standing on edge and ears twitching back against his head as they grew out longer and taller. His nose continued to darken, getting colder and wetter as his tail kept flicking back and forth with every thrust. Those sharp claws sank into the arm of the couch, a leg kicking over the edge of the couch to give him better access to the already soaked cushions below before he thrust heavier and harder and faster.

His heart was pounding in his chest as there was very little left on Trysten's body that was human. The fur spread down his chest as he growled heavier and heavier. His thoughts were completely changed to that of pleasure, thinking only of breeding and mounting instead of anything else he'd worried about before. His growth slowed down, practically overshadowing the couch as his thick, aching lupine shaft rubbed and leaked and thrust along the cushions. His muzzle grew out further before his irises swirled with a golden hue. Trysten blinked a few times, the color solidifying as the last of the fur grew out along his chest and belly. Small nipples dotted out from his body before three lines of dark, black fur grew out from his chest. They each converged at a point, spreading out in thin chevrons as the changes were finishing up quickly. There was almost no sign of Trysten left, but rather a large, snarling, horny wolf taking the couch as his mate. And as those last changes rolled along his body, his humping sped up more and more and more. His lungs heaved as he drank in deep, heavy breaths while his tongue stretched out over fierce, gleaming white fangs. His pants huffed out into puffs of humid air while drool pooled along his black lips and dripped onto the couch. The pleasure was quickly building to its peak, Trysten's already overwhelmed body shivering with every thrust. His legs shook and wobbled, hips thrusting erratically while Trysten leaned his neck forward and bit down on the armrest of the couch in a mating bite. Images of sex and breeding and mounting rushed through his head. He was losing any sense of the already minimal control he had, eyes glazed and overtaken by his instincts as he thrust more. And more. And more. And more. Until his chest heaved. His shaft pulled up against his body. His fangs ripped the fabric off the arm rest. And he threw back his head in a long, heavy, pleasure-fueled howl.

The climax burst from his body in uncontrollable heat, a wildfire burning in his heart as the first shot of his need painted the armrest and his fur in a heavy, uneven white. It rippled through his body as each thrust brought more of that orgasm from deep in his body, his muzzle hanging open in a permanent pant as his arms wavered before collapsing under him. Trysten fell to his side, legs shifting and kicking out in the air as his hips continued to thrust with more of his need shooting onto the coffee table, the floor, his fur, and even the advent calendar which was glowing with that same green and red light as the dog tag from before. The glow erupted as Trysten painted it with his climax, a fire burning in his heart as he quickly shifted onto his back and let out a weak, aching howl before his hips thrust high and hard into the air. Another jet of his need shot high into the air before landing on his fur, painting those black chevrons as time blended together in the throes of his pleasure. He couldn't keep track of how many times his climax peaked, hardly able to keep his thoughts clear and coherent as he rode the rest of that orgasm for as long as he could.

A long amount of time passed before Trysten's arms went limp and his shaft twitched weakly against his body. His chest heaved heavily as he struggled to catch his breath with eyes glazed over from the sating of the most intense need he'd ever felt in his life. His thoughts were a jumbled mess, matching the state of his fur as there were wandering, intermittent thoughts of concern about his life from this point on. How would he go to work? How would he find food? How would he even pretend to live a normal life like this? But each one of those thoughts was quickly overshadowed by his instincts lulling him into a tired, contented state of his afterglow. His eyes fluttered as his tongue hung out of the side of his muzzle, body barely fitting on the couch as his thoughts swirled around in a daze of pleased confusion. Trysten didn't know how this was possible, and he was hardly able to control his thoughts from going wild…but at the end of it all? He felt amazing. And still, that advent calendar sat against the overturned table with his seed painting the cardboard while those runes on the fake fireplace shifted with that same green and red glow. The jumbled icons pulsed with an eerie light, twisting and morphing into words that were just barely legible. And as the glow pulsed from the discarded tag and the advent calendar, the phrase flashed before the energy in the room suddenly faded away:

“ T w e l v e M o r e D a y s ."
