Beacon Hills Halloween

Part 1: Peter

**Disclaimer** - Inspired by the great @ultram0th, and their amazing job at providing top tier Derek Hale transformation stories all month long, I thought I might try and write a few Teen Wolf tf stories of my own. (Plus what better theme to write tf stories to than Halloween.) Please note that this isn’t me competing with ultram0th, or trying to steal their spotlight. I just felt like giving back, after all the great stories they’ve provided us with this month. Which you should definitely go and read for yourselves. This is a three part series, with the final part being released on Halloween (because I’m dramatic.) Hope you all enjoy, and Happy Halloween!

------------------------------------------------------------------------------

This year the pack was throwing a Halloween party, and they had, albeit reluctantly, invited Peter to come. Normally, Peter couldn’t care less about Halloween. Just a day of the year where screaming kids run around in badly made monster costumes, pretending to be the real deal.

However this year, Peter had an idea. He thought it would be fun to wear a sexy costume to get Chris’ attention. The two men have had a not-really-friends with benefits type thing going on lately. He’d told the hunter his plan during the last pack meeting, and asked him for any ideas on what he should wear. The man had just scoffed and called him an idiot. Peter smirked, remembering the faint redness he’d seen on Chris’ cheeks.

Currently, after spending some time out in the preserve, Peter had just come back to his car that he’d parked at the edge of the forest. He was about to head home and get changed for the party, when he spotted a plastic bag lying in the passenger seat. Picking it up to inspect it, he realized that it was one of those cheap, mass produced Halloween costumes that you find at every department store this time of year. The top of the bag was labeled “The Cowboy,” and the picture on the front depicted a bearded man wearing the stereotypical cowboy hat, denim jeans, and cowboy boots.

Peter scoffed, “Really Chris? You couldn’t get something more high quality?” the werewolf said. Thinking that no one else besides the hunter would plant something like this in his car. “Who knows,” Peter thought, “Maybe he has a Brokeback Mountain fantasy? Chris definitely seems like the kind of guy who would,” he smirked. “Still, it could be fun,” he shrugged.

He stepped out of the car, costume in hand. Deciding he might as well try it on here, since no one else was around anyway. Figuring that anyone who happened to be passing by and would see him in just his underwear would be more likely to be aroused than upset. "Besides," Peter thought mischievously, "Maybe Chris is still watching from somewhere nearby. Might as well put on a show for him." Leaning into that thought, Peter slowly and teasingly stripped off his trademark low V-neck, tight jeans, and designer sunglasses; chucking them aside one by one. He then opened the bag and inspected its contents. Inside was a set of stereotypical cowboy boots, a pair of blue jeans, some chaps, a rancher’s shirt, some gloves, and the all important Stetson hat. “Not the most sinful fetish Christopher” Peter scoffed, looking at the remarkably unsexy clothing. “He better pull out all the stops tonight, if he expects me to wear this,” Peter grumbled to himself.

He begrudgingly got dressed in the costume. “Is there actual dirt on these clothes? Is this a used costume?!” Peter complained, noticing the wear and tear of the clothing. He pulled out his phone and used the camera to look at himself. “Well, it could be worse,” he admitted, “But then again, I look good in everything,” he smirked, admiring how the jeans hugged his ass. Yet as he said that, he felt a tingling sensation spread throughout his body.

Peter gasped as he watched the face reflected back at him change right before his eyes. His lower face became obscured, as a dark and bushy beard quickly spread over his jaw. Thicker and more shaggy than anything Peter had ever grown, or would have wanted to grow before. The changes didn’t stop there though, as he could feel an itching sensation spread over the rest of his body. Undoing the top buttons of his shirt, revealed a dense carpet of body hair, that had spread across his previously smooth chest and traveled downward to form a thick treasure trail leading into his jeans. “No No No! I just got waxed last week! What the hell is going on?!” he cried. He then watched in shock as the color and complexion of his skin changed. Where before his skin was evenly colored, thanks to regular tanning sessions, it now appeared redder in some areas and paler in others. His skin also grew tougher and more weathered. Like the kind you’d get if you spent most of your life working outside in the hot sun.

“Nhhhhyyyhhh!”

Peter jumped at the startling sound! Dropping his phone, he spun around to see what the source of it was. He gaped. There, where his Shelby Mustang had been parked moments before, was now an Actual Mustang. A real live horse! “What’s happening?!” he cried out. The horse was obviously spoked, crying out and shifting nervously. Peter, reacting without even thinking, grabbed the lead and steadied the frightened horse. “Easy. Easy. You’re alright,” he said soothingly. As he petted the horse to calm it down, he didn’t even notice his jean covered ass hardening. The muscles becoming even thicker and more dense from spending years riding horses. The back of his jeans stretched and strained tightly against its contents. “That’s it. Good girl. You’re alright,” Peter whispered soothingly to the now calm horse. To show its thanks, the horse gave Peter a friendly lick.

Peter blinked, his mind feeling like it just got reset. His head felt both incredibly full and empty at the same time. What was he doing again? Why was he out in the forest with a horse? Why was he dressed in these clothes? His clothes? Why wouldn’t he be dressed in his clothes? What else would he be wearing? Peter shook his head and chuckled. “Must be spending too much time in the sun, huh girl?" he laughed. Now he remembered why he was here. The herd had broken part of the fence, and some of the cows had escaped into the preserve. He’d been out all morning looking for them, when he’d decided to stop here and take a break.

“Come on ol’ girl, we better get back to it,” Peter said with a traditional southern accent, hopping up onto the horse’s saddle. “It’s too bad I lost my phone,” he thought, “I could have let Chris know I won’t be able to make it to the party tonight. Not with part of the herd missing. I’ll probably be out here all night,” he sighed. What a shame, he'd been looking forward to seeing Chris in a sexy costume, maybe having a little bit of fun tonight. Just the thought was enough to cause the cowboy's cock to stiffen in his dirty jeans. He gave his bulge a few absent-minded gropes with his glove covered hand, before sighing. “Ah well, That’s okay. I never really liked Halloween anyway. Who has time for parties and goofing off, when there's real work to be done,” He chuckled, before riding off into the forest.

Not looking back to see a mysterious figure picking up his discarded clothes. Putting the designer sunglasses, low V-neck, and skinny jeans, into another costume bag. This one labeled, “The Douchebag.”

December 02: Wolfe Glick

00 │ 01 │ 02

“Welcome back to my channel,” streamer and PokéTuber Wolfe Glick said as he flashed his audience one of his cute smiles, “tonight we’re gonna do some Tera Raid battles…”

The cute hunk was in his recording room at his house, enjoying the heater blasting and warming up the winter air. He sat in front of his camera with his dual screen system on the desk in front of him— one screen showing Pokémon Violet and the other his chat. Wolfe had won scores of adoring fans due in part to his status as a world champion in Pokémon battling and because of his cute nerdy guy aesthetic. Still, it was obvious that he took care of himself, as was evident by his toned muscles that were barely visible beneath his tight tank top.

Wolfe got the game set up and began to read off the chat, thanking the donations that were starting to come in. He paused when he saw that a new username, HypnoGuy72, had posted a gif that looked like a spiral that was circling around in a mesmerizing manner into the chat that was continuously scrolling.

The man cocked his eyebrow in confusion as he stared at it, his muscles gradually relaxing as his jaw went slack.

As the rest of the comments popped up, the gif disappeared down the line and Wolfe snapped out of his daze.

“Whoa, um… sorry about that,” Wolfe muttered, shaking his head as he wondered just why he’d spaced out. He blushed a little bit and cleared his throat as he grabbed his pro controller. “Um, let’s go ahead and get started, shall we?”

As he played, Wolfe started to squirm a little in his seat, seemingly unable to stay still for some reason. The presence of his webcam, with its shiny glass eye, weighed heavily on the streamer’s mind unlike ever before, and the more the chat spoke up, the more Wolfe began to feel some sort of giddy excitement.

Obviously, Wolfe loved to stream, which was why he followed down this career path, but he’d never felt his heart race so heavily in his chest before… nor had he ever gotten so rock hard on stream before.

Wolfe flinched when he felt his cock plump up to its full size, thankful that it was hidden underneath his desk. His heart raced even faster, and Wolfe even had to wonder if it was because of embarrassment or excitement.

For some strange reason, the streamer felt a foreign exhilaration at the thought of being hard on stream. He wanted to try his best to ignore it and try to finish the stream, forcing himself to play the game before him.

“Um, so we can go ahead and face this six star raid— Ooohhh.” Wolfe’s eyes widened to the size of saucers as he broke off mid-sentence, bellowing out a low moan. He winced when he finally registered that one hand held his pro controller, while the other thumbed a hard nipple.

Wolfe felt his face turn bright red as he realized that not only had he just played with his nipple on stream for all of his followers to see, but he’d also enjoyed it as was evident by his hard cock.

“What the hell is up with me?” he muttered under his breath before turning back to face the camera full on, again, his heart racing once he was on-screen dead on. “Um, yeah, sorry about that guys…”

He trailed off when he heard the pro controller clatter onto the hard desk. As if they had a mind of their own, both of Wolfe’s hands moved on their own accord up towards his tank top. They roughly yanked on the neck hole to bring it downwards so that his plump pecs were entirely exposed. He didn’t know what was going on, but as soon as his hands latched onto his sensitive nipples for the stream to lust over, all Wolfe could do was moan loudly.

Wolfe tried to tell himself to stop, but the more he saw the chat respond, the less control over his actions he appeared to have.

The stunned hunk felt himself raise one arm, flexing a sizable bicep for the camera. He inwardly screamed as he felt himself lean forward and lick it seductively, moaning loudly for everyone watching. All the while, his other hand still toyed with his nipple.

Wolfe felt as if he were a puppet tied to strings, and someone other than himself was in charge of his actions. He desperately tried to stop feeling himself up on camera, but the more he saw people logging in to watch his stream, the more intense his impromptu show turned.

The bewildered hunk tore his pants and boxers down as he scooted his chair further back to allow his hard cock to bob in the air for everyone to gawk at. Despite his inner panic, Wolfe felt a smirk form on his handsome face.

With one hand, he reached down and wrapped a fist around his throbbing cock and began to jerk it off on camera. With the other, he reached behind himself, sliding a few fingers between his plump cheeks to play with his tight hole. His face twisted into a visage full of utter pleasure and joy as he pursed his thick lips and let out moan after slutty moan.

As he pleasured himself, Wolfe’s body decided to up the ante as it began to bounce slightly on his intruding fingers. Each movement shoved his invading digits further into his sensitive hole, eliciting more hungry moans from the slutty stud. Each impact caused his pecs to bounce a little and he couldn’t stop the little shimmy he added to his waist that caused his cock to wag tantalizingly in the air. Everything he was doing was for a show, and although he was aware of all that he was doing, Wolfe was powerless to stop any of it.

Deep down, Wolfe begged himself to stop, but he wasn’t in control of his body. Worse was that a growing part of himself was loving showing off in such a sexual manner on camera for his thousands of followers to lust after. There was a growing part of him that was excited to be naked and jerking off like a camboy whore for all to see, and that thought made his cock throb even more.

The chat exploded with donations and cheers from men enjoying the show, many of them subscribing in the hopes that there’d be more to see. Wolfe was too caught up in pleasuring himself that he didn’t see HypnoGuy72’s new comment flash upon the screen:

That little spiral hypnotized the poor stud into becoming a camwhore. He can’t help but act like a gay slut whenever he’s on camera now!

“Uunghh!” Wolfe squealed as his cock shot out streams of cum that landed all over his chest. He panted as he tried to catch his breath, his pecs heaving with the motion.

The dazed streamer struggled to piece together what had just happened. Deep down, he was humiliated over his seemingly uncontrollable actions, but there also existed a large part of himself that had loved the whole experience.

He’d loved it so much that, despite having just came, his cock was already rock hard all over again as the naked stud sat in front of the camera.

He smirked again. “Ready for Round Two?” he asked his followers, as he began to thumb his hard nipples again.

UltraM0th's 2024 TF Advent Calendar!

Yay! It's Christmas Season! (Truth be told, I prefer Christmas Season to Spooky Season...)

Therefore, it's time for the 2nd TF Advent Calendar! Everyday until Christmas, there will be a new snippet of a hot guy being transformed to your pleasure! If this goes well, then I'd love for this to become an annual event. I hope you all enjoy!

My apologies if your guy didn't make the cut. There were loads of suggestions, so I had to do a first-come-first-serve/tally system.

🎄ENJOY!

Hey Ultram0th, I hope your move is going well! I was scrolling through Gay Spiral Stories and came across your Eric’s Sponsorship story. The first 2 parts were amazing, and I’d love to see what happens afterwards if you’d be down to continue it! Thanks!

I would like to continue that, and I haven't totally given up on it 100% yet! I know that it's been a while, but I just have other projects I'm concentrating on at the moment.

But never say never! I do have a little bit of the third/last part on my laptop, I just have to buckle down soon!

Sorry, I know that's not the greatest answer...

Finished version of Gato-Cat / UltraM0th’s Christmas story involving Derek Hale undergoing a The Santa Clause style transformation. Was originally posted last year, but was lost when their old account got deleted. I downloaded and saved a copy of the story before it got deleted, so I figured I’d repost it, so that everyone can enjoy it once again.

Of course, all credit goes to Gato-Cat, so make sure to go and follow them for more great content like this.

@gato-cat

A/N: Here’s a fun Christmas story that plays with the plot of The Santa Clause, but it involves Derek Hale from Teen Wolf turning into the jolly, big guy. I hope that you all enjoy it. And thank you to @writer-ofstuff for helping me bounce off ideas for this!

I hope you all enjoy the holidays!

“Der!” Stiles hissed under his breath as he shook the werewolf beside him awake. “Wake up!”

“Hrmm?” Derek yawned, tightening his hold on his boyfriend in an attempt to silence him. After weeks of defending Beacon Hills from yet another supernatural threat, the werewolf was relieved that he and Stiles could spend their first Christmas together as a couple in peace.

“No, no, no!” Stiles panicked, his heartbeat really high. “I heard something walking around on the roof.”

The alpha werewolf immediately shot up and instinctually shoved the small human behind him, straining his ears. Sure enough, he could hear heavy footsteps on top of his repaired house, the wood creaking as it seemed to support something’s weight.

“Stay here,” Derek growled to his boyfriend as he stormed out of the bedroom and hurried downstairs. He made sure to flex his massive muscles in an attempt to look all the more threatening. Given his alpha status and his regular workouts, Derek Hale’s physique was blessed with muscles that popped and oozed masculinity. His massive pecs were puffed out as he bared his teeth, stalking out onto the snow-covered front lawn.

The werewolf sniffed at the wintery air, catching a whiff of what he thought was cinnamon and sugar— something disgustingly sweet, making him recoil at the scent.

Peering up into the night sky, Derek could barely make out the large silhouette of someone skulking around on the rooftop, heading towards the chimney.

“Hey!” Derek roared up at the unknown figure, using his booming alpha voice to scare it. “What do you think you’re doing?!”

The shadowed figure up on the roof jerked back in shock at the alpha’s baritone, quickly losing its footing and tumbling down the icy roof, falling to the ground with a loud thud. Derek slowly approached the figure, his fighting stance ready, as he took in the sight of whatever it was that had fallen from his roof. The figure was cloaked in a large red fabric that had white trimming. Its overwhelming sugary scent made sense a little bit when Derek took in the fact that the creature was rather large, and based on the slight jiggle its body had upon impact, there was a large amount of fat on it. There was white curly hair that obscured its face... no way.

“Derek!” Stiles gasped as he rushed outside, a baseball bat in his hands, pausing when he took in the sight before him. “You killed Santa Claus!”

The werewolf looked back to meet his boyfriend’s horrified eyes, instantly growing defensive. “I did not!” he countered. “The guy fell on his own!”

“I’m still alive, Mieczysław,” the injured Santa Claus muttered face down in the snow. With a grunt, the old man turned over onto his back. “Now if I could get some help, that would be nice.”

Derek looked over at the red-faced Stiles at the mention of his first name, but before he could ask, his boyfriend held up a hand.

“We should help him inside,” Stiles hurriedly said as he dropped the bat and rushed forward to help drag Santa inside the house.

Derek huffed, but nevertheless helped his boyfriend, winding up doing most of the work. He plopped Santa Claus onto the couch in the living room, struggling to put two and two together.

“So, uh,” Derek mumbled as he paced the living room, “you’re real?”

The supposed fairy tale man chuckled, even going so far as to grab the sides of his jiggling gut. “Of course I’m real, Derek,” Santa Claus laughed. “You’d think that in a world with werewolves that Santa Claus would exist too, right?”

“He does have a point,” Stiles chimed in as he entered the living room to hand the jolly old man a cup of coffee. “So does this mean that Krampus is real too? Because I’ve read about him before and he sounds really creepy and like something I’d like to avoid.”

“Yeah, he’s down the block,” Santa said, ignoring the look of fear on the human’s face. “However, we have bigger issues afoot. With me injured right now, I need someone to help deliver the rest of the presents in my sleigh.” He looked at the alpha werewolf with expectant eyes.

Derek wanted to argue but Stiles also looked at him with the same expression, and he felt his resolve quickly melt. “Fine,” he grunted. “What do I have to do?”

Santa Claus smiled and took off his trademark hat, shucking his redcoat as well. “First, put those on,” he instructed.

Derek did as he was told, sliding on the massive coat that was three sizes too big for him, making it look like he was swimming in the soft fabric that actually felt good against his bare chest. Lastly, he put on the hat.

“Now, eat this,” Santa said as he pulled a gingerbread cookie out of his pocket. “It will transfer some of my powers to you.”

With a huff, Derek took the offered cookie and quickly ate it, a little surprised at how good it was considering that it’d come from an old man’s pocket. “Okay, now what?” he asked, crossing his arms over his chest. There was a slight itchy sensation around his face and he reached up to scratch his beard... wait.

Derek gasped as he ran his hands over his face, feeling the beard that had seemingly sprouted out of nowhere. The shocked werewolf darted over towards a mirror and looked in it, paling when he saw the beard that now dominated the lower half of his face. It wasn’t as bushy as the titular Santa Claus’s, but it definitely looked like it would’ve taken about a year for the man to grow. It was still his usual black, yet there were trace flecks of white that he could see in it.

“What the hell is this?” Derek demanded, turning around and pointing at his face, even stomping his foot out of irritation. That last action made him wince when he felt an unfamiliar jiggling at his gut.

Derek looked down in time to see his body quickly inflating, with most of the growth centered around his stomach. His abs filled in before his stomach was flat, which then pushed outwards. His gut grew larger and rounder, jutting away from his torso until it completely filled the red coat he was wearing, making it the perfect fit. Even his pecs inflated, filling up with fat until he had sizable muscletits that weren’t just toned. Derek was slightly relieved to see that he still retained all of his hard-earned muscles, they were just covered by a thick layer of fat, making him look more like a beefy version of Santa Claus. His arms followed suit, losing their definition as they packed on more meat. He blushed furiously as his thighs widened and he felt his ass puff out and get more jiggly, stretching the confines of his sweatpants to the limit.

Once his transformation was done, Derek stood in shock for a moment as he examined his newly inflated form.

“What the fuck did you do to me?!” he shouted as he tried to stalk threateningly over towards the couch, but he inwardly flinched when he felt his new gut jiggling with every step he took.

Santa Claus didn’t look fazed and instead snapped his fingers. “You better hurry up,” he said. “There’s a lot of houses I haven’t gotten to yet.”

Before he could argue some more, Derek felt an unknown force yanking him towards the chimney. He was glad that there wasn’t a fire in there because said force tugged him into the actual fireplace, squeezing his new bulk through the chimney with such ease he might as well have been greased. It spat him out onto the roof and once he saw the sleigh and the reindeer, he knew just what he’d gotten himself into. The sleigh was just as he’d seen on Christmas cards, being red with golden trim. In the back was a large white sack that was loosely tied at the top with various toys sticking out of the opening.

“This is gonna be a long night,” the bulky werewolf sighed as he hopped into the sleigh, wincing as he felt his inflated gut settle into place on his lap.

There was a metallic clang followed by the huffing of Stiles climbing a ladder. He made it to the rooftop, clad in a thick winter coat and sweatpants. “Wait up!” he gasped. “I’m coming with you!”

Derek looked at the falling snowflakes and shook his head, the white pompom on the Santa hat waving around like crazy from the motion. “No way,” he grunted. “It’s below freezing, you’ll catch a cold.”

“I’ll just huddle up next to you,” Stiles countered as he started to climb inside the sleigh.

The inflated werewolf knew it was no use arguing with his stubborn boyfriend. “Fine,” he muttered, scooting over to the side of the sleigh to make room.

Stiles squeezed himself inside the sleigh, one side pressed against the hardwood of the sleigh and the other squishing into the sides of Derek’s new bulk. “Um, can you scoot over a little bit?” he asked. “There’s barely any room.”

The blush on Derek’s bearded face deepened to match his coat. “I’m already all the way over to the other side,” he growled. The werewolf tried to shift over some more, his inflated bulk jiggling wildly as he tried to make room. However, his widened hips were already pressed against the other side of the sleigh. His rotund gut took up the most room and it felt really heavy on top of him, impeding most of his movements. With an annoyed grunt, the werewolf maneuvered a heavy arm over the human’s smaller shoulders and pressed him against his squishy bulk in an effort to make more room.

Stiles grabbed a hold of the reins and yanked on them. “Mush!” he excitedly yelled out... but the sleigh stayed put.

One of the reindeer even looked over its shoulder at him and snorted.

“I think it has to be me,” Derek sighed, taking the reins from the disappointed Stiles. As soon as they were in his beefy hands, the sleigh lurched forward as they flew off the roof and into the night sky.

Out of instinct, Stiles tried to wrap his arms around Derek as they flew, but he couldn’t wrap his arms around even a third of the chubby version of his boyfriend. However, that brought about another issue to the alpha werewolf.

He fought a hiss at the feeling of the much smaller Stiles squeezing against his large gut, the action sending foreign shivers of pleasure throughout him. He hadn’t noticed until he saw it curling over the opening of the coat, but even his chest hair had grown in during his transformation, making him look like a total bear. The hairs only served as pleasure receptors, amplifying the intense feelings he had as Stiles brushed up against his sensitive chest and gut. He couldn’t tell if the nubs poking against the coat caused by his larger nipples were from the blistering cold or from excitement. The way his cock was hardening (and totally concealed by his cresting gut) told Derek that it was the latter.

Derek was embarrassed at first because of his sudden one-hundred pound weight gain, but now he was utterly distraught to find that his new gut was incredibly sensitive. A small part of him was relieved when the reindeer landed on another rooftop, but a louder part was disappointed when Stiles let go of him, leaving behind tingling want all over his jiggling mass.

Still struggling to make sense of what was going on, Derek climbed out of the sleigh, having an awkward time getting used to walking around with thighs that kept pushing against each other and a gut that jiggled with every step. He grabbed the sack from the sleigh and waddled over to the chimney, stuffing it down first.

The alpha werewolf then positioned himself on top of it and started to go down feet first. He managed to fit his thick thighs and widened hips in, thankfully squeezing his bubblebutt inside too. However, Derek groaned loudly when his large gut got wedged in the chimney, making him stuck.

“You’ve got to be shitting me!” Derek roared out in frustration. “What’s the point of making me grow this!?” He gestured at his large gut as he tried to wiggle himself free.

“The only thin Santas you see are in porn?” Stiles meekly offered as he hopped out of the sleigh to try to help. “Try sucking it in.”

“I am sucking it in,” Derek growled, his gut far to large to make his efforts noticeable.

It took a bit of maneuvering and dedication, but the Santa Derek eventually managed to squeeze himself through the chimney—thanks to Stiles’s suggestion of thinking “Jolly Thoughts” so as to give more into the Santa role. He’d thought that it was stupid, but humored him anyway, only to be sucked down the chimney in an instant.

“That was weird,” Derek huffed as he found himself standing in the living room of the unknown house. Wanting to waste no time at all in case someone sees him (or worse recognizes him and laughs at the fact that he’d been turned into Santa Claus) he quickly went to literally throwing the toys out of the bag and aiming them at the Christmas tree. It wasn’t long until the bag was empty, which he automatically knew somehow that it would magically refill at the next house.

Derek breathed a sigh of relief and went to head back towards the chimney when the delicious aroma of sugar wafted by his nostrils, making his big stomach growl hungrily.

The werewolf turned to look in the direction of the scent, rolling his eyes when he saw the plate of cookies and the glass of milk that was on the coffee table. As soon as he made eye contact with the cookies, his stomach growled even louder.

“Really?” he whined, even grabbed at his protruding gut in irritation. “I don’t even like sweets.”

His stomach growled much louder now and he worried that it’d wake up the occupants in the house.

“Fuck,” he hissed under his breath as he waddled towards the coffee table. The cookies looked like they were from a holiday collection from the grocery store, containing an array of sugar cookies iced and decorated to look like trees, snowmen, etc. Derek could feel himself drooling as he stared at them and he picked up a snowman shaped cookie, taking one bite of it.

As soon as his tongue tasted the sweet sugar of the cookie, he couldn’t stop himself from greedily scarfing the rest of it down. In a frenzy, the werewolf bent over and hungrily ate the rest of the cookies, barely able to control himself enough to pocket one for Stiles, before downing the glass of milk.

His stomach felt satisfied and Derek patted it contently, noting that it had bloated the smallest bit from his quick eating, looking slightly rounder. “Of course...” he grunted as he rolled his eyes for the thousandth time that night. He turned to leave, but his protruding gut knocked over the standing lamp that he was next to, making it crash to the ground. He quickly waddled back over to the fireplace and was sucked up through the chimney, landing gracefully on his feet on the roof.

“How’d it go?” Stiles excitedly asked.

“It was fine,” Derek muttered. “Oh... here.” He handed his boyfriend the cookie before settling back into the sleigh. Again, he fought back a moan as Stiles settled back into place and snuggled up against his sensitive bulk. He wrapped his arm around the human and they took off to the next house.

“Der,” Stiles said, looking up the werewolf Santa Claus, “you have cookie crumbs in your beard.”

The rest of night followed the similar pattern: Derek would nearly blow a load in his pants over having Stiles rub up against his sensitive bulk, he would be sucked down into a chimney, he would place the gifts under the tree, he’d gobble up every last cookie that was left for Santa Claus, he would get sucked back up the chimney to the roof, and he would get excited at the idea of Stiles rubbing up against his gut again. By the end of the night, Derek had fallen into that routine and had completed every house without an issue—except for Scott’s where Scott had woken up and had laughed at the Santa Derek with the jiggling gut and bushy beard, making Derek growl and storm out the front door instead of taking the chimney.

Despite that, Derek started to look forward to the times when he and Stiles would be flying through the air and the latter would press against his bulk. When they’d flown through the cold Finnish airspace, Derek had opened up his coat to let Stiles use his body heat, and he’d came on the spot at having the human nuzzle against his hairy gut and inflated pecs. Stiles was none the wiser, happily enjoying the ride and experience, all the while Derek was humiliated beyond belief, thankful that his new beard hid most of his blush.

Finally, as soon as the sun was beginning to rise, Santa Claus was starting to feel better as he relaxed in the Hale House.

The inflated werewolf plopped out of the fireplace and tumbled onto the living room floor, groaning as he rested on his back, completely exhausted from his busy night of having to deliver presents to all the children of the world.

“Derek!” Santa cheerfully greeted him. “How was it?”

The stunned werewolf grunted and rubbed the tiredness away from his eyes. “Damn,” he grunted, “that was definitely an experience.” He tore the hat away from his head and stood up to take off Santa’s coat, frowning at the sight of his inflated, hairy body.

After a few seconds, Stiles hurried inside the house through the front door, still all smiles. “That was amazing!” he said.

Santa Claus smiled warmly at the werewolf before standing up. “Thanks a lot for your help, Derek,” he chuckled. “I’ll make sure to add you to the Nice List.”

“Wow, that’s super awesome,” Derek mocked. “Now change me back!” He gestured down at his gut which blocked the rest of his view of his lower body.

Santa Claus shrugged his coat back on. “Sorry Derek,” he said as he pulled his hat on. “There is no antidote for that, but maybe I can call on you for help next Christmas?” The magical man gave the couple a wink before disappearing up the chimney in a flash, leaving no chance for argument.

Derek felt his new gut drop at what he’d just heard. Not only was he stuck with the beard and the sensitive gut, but he was expected to help out and be Replacement Claus next year too? “You’ve got to be shittin’ me,” Derek growled as he grasped at his hairy gut, giving it a tentative poke. He was panicking over how much his life was going to change by being the werewolf Santa Claus when he caught another whiff in the air, this one emanating from his boyfriend who stood beside him.

Stiles was turned on.

“Really?” Derek asked, cocking his eyebrow at the human as he gestured at his gut and beard. “This does it for you?”

Stiles blushed a little bit and had a hard time maintaining eye contact with the beefy werewolf. “I like my men big and hairy,” he quietly admitted.

Now Derek may have loved to work out and loved to use his large muscles to his advantage, intimidating any threat that dared to cross into his territory, but he loved Stiles even more. Therefore, the sight of his boyfriend blushing made his heart flutter and the werewolf started to realize that maybe being beefy and hairy wouldn’t be too bad... especially if he could get Stiles to rub up against his gut some more.

“Well,” Derek blushed back, wrapping an arm around his boyfriend’s waist to pull him in close to his inflated form, squeezing him tightly against his new hairy gut enjoying the way it immediately made his cock rock hard, “ho, ho, ho.”
