Getting into the Christmas Spirit

Hey folks! It’s a bit late, but here is my Christmas Special for this year!

The theme this time is transformation. I tried doing something different for this one, focusing on a single character in his transformative journey. It was pretty fun to write!

Story synopsis: A week before Christmas, a young man receives a mysterious package that’s going to change his life in a big, hairy way. And maybe not just his own...

Unlike most of my stories, this one is set in the “real world” (specifically in Santiago, Chile), so there are a couple local references here and there, as a fun little nod. Remember that Christmas is in summer in the Southern Hemisphere! That must be awkward for Santa...

Content warning: This story portrays a human character suffering multiple involuntary changes to his body over the course of a week via magical means, including weight gain, muscle growth and body hair growth, alongside increased libido, mental corruption and loss of identity, culminating in a full transformation into a very horny and Christmas-obsessed anthro polar bear.

Story length: ~4800 words.

That’s all from me for 2023. Have a good end of year!


Monday, December 18th

Marco was searching for the key to his apartment and didn't notice the box next to his door until he tripped on it.

“Fuck! Who leaves a box in the middle of the hallway?"

He bent down to pick up the box. It was a small, unassuming cardboard box with his name and address written on it, and nothing else. He hadn't ordered anything online, so he had no idea who could've sent it or why it was left there instead of in the lobby.

“Weird…"

Marco shrugged and entered his apartment, carrying the box under his arm. He'd had an exhausting day at work, so he was looking forward to having a relaxed, unproductive evening.

The first thing he did after leaving the mysterious box on the table was opening the windows and turning on the fan. Then, he took off his shoes and his sweaty shirt. The weather in Santiago was unbearable at this time of the year.

“Man, summer hasn't even started yet and it's already hot as fuck."

He went to the bathroom, drank a good amount of tap water, and then put his head under the refreshing stream.

“Ahhhh, much better."

His scrawny reflection looked at him from the mirror, water dripping from his head through his hairless chest.

“I should take a shower," he said after a quick sniff of his armpits.

But first, he wanted to find out what was inside that weird package. Not bothering to dry his wet torso, he left the bathroom, got a knife from the kitchen, and opened the box.

To his surprise, there was another, smaller box inside, wrapped in Christmas-themed paper, with a red ribbon and everything. There was a tag too, with a handwritten message that said “DO NOT OPEN BEFORE CHRISTMAS" in big red letters. There was no name attached.

“Huh. I wonder who sent me this."

Marco didn't really care that much about Christmas, especially now that he wasn't a kid anymore, but he was still intrigued. He gently shook the present, trying to guess what it could be from the sound or the weight, but to no avail. He was curious to know what it was, but he assumed that whoever sent it must've written that message on the tag for a reason, so he decided to let it be for the time being.

He put it back inside the cardboard box and went to take a refreshing cold shower. The rest of his day continued without incident, and he eventually forgot about the mysterious Christmas gift.

Tuesday, December 19th

Marco woke up moaning.

It took him a moment to realize what had happened. He was panting, his body completely covered in sweat. And not just that. A pool of cum had formed on his abdomen, next to his still hard, throbbing cock.

A wet dream. He hadn't had one of those since he was a teenager. He closed his eyes, trying to remember what the dream was about. There was a man. A big, imposing man with a deep voice, although he couldn't visualize him clearly, or remember what he said.

He rubbed his eyes and sighed. Then his alarm clock went off.

“Well, time to get up, I guess. I'll have to change the sheets later…"

Marco did his best to proceed with his usual morning routine. As he was about to leave for work, he saw the cardboard box and stopped in his tracks. He grabbed the present and held it in his hands, contemplating it.

“What am I doing? I'll be late for work!" he said after a while.

He shook his head, left the box on the table, and exited his apartment.

While waiting for the bus, Marco put on his headphones and opened his usual music app. Without thinking, he picked a Christmas playlist. He laughed out loud as the music started playing, just then realizing what he'd done. Why did he do that? He never listened to Christmas music if he could avoid it. Still, for some reason he couldn't bring himself to change it, and continued listening to it until he arrived at his workplace.

It was a weird day at work. The end of the year was stressful on its own, but Marco also was unusually distracted. He had Christmas music stuck in his head all day, and he couldn't stop thinking about the mysterious gift he'd received the previous day. Sometimes he could even feel his heartbeat accelerate when thinking about it.

“Come on, man, focus!" he said to himself during a bathroom break, trying to clear his thoughts.

But he couldn't. The rest of his work day was just as unproductive, and even on his way back home, he couldn't think of anything else.

When he got home, he immediately went to grab the cardboard box and held it in his hands, excitedly.

He was sweating, and not only because of the hot weather. His entire body felt weird. His hands trembled in anticipation, and for some reason, he had an erection.

Marco took the present out of the cardboard box and looked at the “DO NOT OPEN BEFORE CHRISTMAS" message again. Whoever sent him the gift must've had a reason to write that, but it probably wasn't such a big deal if he opened it anyway, right? Otherwise they wouldn't have sent it so early…

He hesitated for a moment, until his curiosity got the better of him.

“Bah, fuck it," he said as he ripped the wrapping paper.

Inside was a small figurine of a polar bear in a Santa Claus outfit. Marco laughed. He wasn't sure what he was expecting, but this was certainly not it. Not that there was anything wrong with it, but after having fantasized so much about it, it felt… very underwhelming? He wondered who could've sent it, and why they seemed so adamant that what was clearly a Christmas ornament wasn't to be opened until Christmas.

He looked at the figurine. It was certainly cute, although its expression was somewhat weird. It almost seemed… judgmental.

“What, are you disappointed that I opened you early?" he said to the bear. “Does that make me naughty?"

He laughed again and left the figurine on the table, next to the diminutive plastic tree that amounted to the only Christmas decoration he had in his apartment. It was relieving, in a way, not having to wonder about the present's identity anymore.

Marco assumed he could now move on with his life. He really meant to. But he still felt inexplicably anxious. And horny. Well, he knew how to deal with that last problem, at least.

He went to his bedroom, quickly got rid of his clothes, and lay on his bed. The sheets still showed evidence of his earlier wet dream, but he didn't care. He didn't even search for porn, as he usually did. He just went straight to stroking his painfully hard cock.

“Fuck…"

Even as he masturbated, he had Christmas music stuck in his head, and the mental image of the bear figurine looking at him.

“Santa…?"

He wasn't sure if the figurine was meant to represent Santa Claus himself as a polar bear, or just a random anthropomorphic bear wearing the classic red outfit. Regardless, he imagined him standing there, not as a figurine but as a full-sized bear person, watching him masturbate.

“Have I been naughty, Santa?"

It was a silly thought, but it made him even hornier, and it wasn't much longer until he shot a pretty generous load on his belly.

“Damn…"

Marco panted as he recovered from his orgasm, feeling slightly less horny but more confused than before. After a while, he realized that he hadn't opened the windows or turned on the fan when he got home, so the air in his room was quite hot and musky. He fixed that before going back to lie on the bed, not even bothering to clean up the cum on his belly just yet.

A few minutes later, he felt his belly rumbling. Weird, he thought, he shouldn't be that hungry. But still, he went to the kitchen and cut a slice of the pan de Pascua he'd bought at the supermarket a few days ago. It wasn't as good as the one his aunt made, but still decent. He ate it in a second and found himself wanting more, so he cut another slice… and another…

Before he knew it, he'd eaten the entire thing. He stood there, naked, looking at the empty plate in disbelief. The most baffling part was that he was still hungry. He opened his fridge. There wasn't much food in there, and soon there was even less.

“Alright, that was enough," he said, forcing himself to leave the kitchen even though he still didn't feel completely sated.

He felt strange, slightly dizzy. He sat on the couch and turned on the TV. The next thing he knew, he was watching some silly Christmas movie. He wasn't even paying much attention to it, but he felt unexpectedly excited whenever certain elements appeared, like Christmas trees, or anything related to Santa.

The movie ended, and he started watching another. He didn't realize that he had another erection and he was absentmindedly rubbing his cock. At some point, when he heard Santa's classic laugh, he came.

“What the fuck…?" he said, looking at his cum-covered hand.

He went to sleep very confused that day.

Wednesday, December 20th

Wednesday was even weirder. When Marco woke up, he felt… heavy. Indeed, when he looked at his midsection, he had a bit of a tummy for the first time in his life. He was perplexed. He knew he'd eaten a lot of food last night, by his standards at least, but how could he have gained so much weight in such a short time just from that?

When he left his bedroom, he saw the polar bear figurine on the table, and his cock throbbed in arousal.

“Fuck, not now!"

It was hard, but he managed to resist the urge to jack off. He had a bigger than usual breakfast, and then left his apartment.

He arrived at work on time, but he was even more distracted than the previous day. He was constantly hungry, his belly growling loudly every once in a while, which was quite embarrassing. And if that wasn't enough, he often got aroused for no reason and had to awkwardly hide his frequent erections.

When he got home after enduring the excruciating work day, he immediately unzipped his pants and started masturbating furiously.

He looked at the bear figurine. The figurine looked at him.

What…?

Marco stood up and went to grab the figurine before sitting on the couch again. It had the same judgmental expression as the previous day.

“Fuck you…"

Marco pressed the figurine against his crotch as he continued jacking off until he came, covering it with cum. He held it there, next to his cock, watching as his cum slowly dripped through the bear's front. That made him feel guilty, somehow.

“Sorry…" he said to the bear. “I don't know what's happening to me."

His belly growled, reminding him of how hungry he'd been all day. Carrying the cum-covered figurine, he went to the kitchen and hastily cleaned it before opening a bag of Christmas cookies.

He'd eaten half of them when he suddenly realized he didn't remember having bought them, but he just shrugged and continued eating. After finishing the bag, he immediately opened a second one, and then another.

Then he felt thirsty, so he opened the fridge and grabbed a bottle of cola de mono. He didn't remember buying that either, and he'd always considered that drinking alcohol alone at home was sad at best, but he didn't care this time. He poured himself a glass and drank it all in one gulp.

“Fuck, this thing is stronger than I expected."

Despite that, he poured himself a second glass of the deceptively sweet drink. Marco was sure he'd regret it the next morning, but he couldn't bring himself to stop.

So he didn't stop.

Thursday, December 21st

Marco woke up unsurprisingly hungover. His stomach also hurt, from having eaten far, far more than he was normally capable of.

As he rubbed his bare belly, he felt that something wasn't quite right. Yes, he'd gained even more weight overnight, that wasn't that surprising at that point. But there was something else. It took him a few seconds to realize that his abdomen was considerably hairy.

“Holy shit!" Marco exclaimed, sitting up and feeling his also hairy chest.

He ran to the bathroom and looked at his reflection. He was almost unrecognizable. His entire torso was covered in a thick carpet of hair, and so were his arms. Not only that, he also had a full beard, despite having shaved the previous day.

“What the fuck is happening to me?!" His voice also seemed much deeper than usual.

He couldn't go to work like that! He frantically searched for his razor, but then he realized that he'd never had to shave a full beard. Grabbing a pair of scissors, he trimmed it as much as he could first, before shaving the entire thing. It worked decently enough.

Once he was done with the beard issue, he picked a long-sleeved shirt to hide his hairy arms. Awkward with such hot weather, but it'd have to do. He had no idea how he'd hide the fact that he was considerably bigger, though. But he was already running late for work, so he couldn't dwell on that.

Still, when he was about to leave his apartment, he stopped to look at the bear figurine. That damn thing! Was it somehow at fault for the weird changes in his body? No, that made no sense. It was just a shitty Christmas ornament.

Why did he get hard every time he looked at it, though?

“Fuck this, I'm late, fuck, fuck, fuck!"

He could swear he felt the bear staring at him as he left.

* * *

“Well, that was better than I expected," he said, back at home, pleased with himself.

He'd already eaten an entire pan de Pascua and was going through his third bag of cookies. Thankfully, his pantry was well-stocked. He wasn't sure when he'd bought all that, but it was irrelevant.

He didn't remember buying the Santa outfit either. He looked at the thing in confusion. It was huge. Far too big for him, even at his new size. Still, he put it on. It felt weirdly comforting to wear, despite the heat. He almost regretted shaving his beard that morning, although when he touched his face, he noticed that it was already growing strong again.

His phone vibrated, taking him out of his thoughts. He checked it to find a message from one of his coworkers, asking if he was okay. He also had multiple missed calls from his boss.

That's when he realized it.

He didn't go to work. He remembered leaving his apartment that morning and walking in a hurry to the bus stop, but then…

“Shit…"

He could come up with an excuse, right? A totally reasonable and believable excuse that didn't involve him suddenly getting hairy and fat while slowly losing his mind… right…?

And where the fuck was he all day, if he didn't go to work?

It didn't matter.

He was hungry. And he was horny.

Friday, December 22nd

Marco didn't even bother trying to get up and go to work, or at least calling in sick. After a couple more calls from his boss, which he consistently ignored, he just turned off his phone and put it in a drawer.

No need for such negativity so close to Christmas.

As he'd come to expect by then, his entire body and especially his belly had grown even more overnight. He lay naked on his bed, rubbing the hairy dome with one hand while casually stroking his hardening cock with the other. He was pretty sure he'd grown a bit down there too.

It eventually turned into a proper masturbation session. Touching his changed body turned him on immensely. This was who he was always meant to be. Or at the very least, he was getting close.

After his orgasm, he took a quick shower and then put on the Santa suit again. He was pleased to find out that it fit him almost perfectly now. Moreover, his beard had fully grown, and he could even see some white hairs here and there. There was barely anything left of the scrawny guy he used to be, and he couldn't be happier.

When he returned to his room, he brought the bear figurine with him and put it on his nightstand. Its presence was comforting to him.

“Isn't this nice? Just the two of us, enjoying the festive spirit, with no one else to bother us."

The bear said nothing.

“Although… I don't think this apartment is festive enough as it is…"

Luckily he had plenty of boxes full of Christmas decorations he'd got… somewhere… at some point… maybe…

Marco shook his head. It didn't matter how they got there. All that mattered was turning his dull apartment into something more appropriate for the season. Still wearing his Santa outfit, he opened the first of the boxes and started setting up lights and decorations throughout his whole apartment. Better late than never!

A couple hours later, he proudly looked at the fruit of all his hard work. This was much better. The festive ambiance got him quite aroused, so he spent most of the rest of the day masturbating and eating, often at the same time. He soon lost count of the number of orgasms he'd had.

He loved Christmas so much.

Saturday, December 23rd

Marco couldn't stop smiling when looking at his reflection in the mirror. Every single hair on his body had turned white as snow overnight. Not only that, he was even hairier than before! It almost seemed like… fur…

He passed his hand through the carpet of silver hair on his massive chest, loving how it felt to the touch. Despite his appearance, Marco didn't feel old. Quite the opposite, he felt full of energy and vitality. His new body wasn't just fat, he'd also gained a considerable amount of musculature, something he'd never had before.

He flexed his biceps and continued admiring his magnificent body for a good while, until he couldn't ignore his erection any longer and had to masturbate again.

Just like his cock, his balls had also grown a decent amount, and his orgasms were more intense and more productive than before. There were cum stains everywhere in his apartment that he didn't bother cleaning anymore. And soon enough, he added a new one. If the summer heat wouldn't let him have a white Christmas, he'd make his own.

When he wore the Santa outfit that day, it fit him perfectly, as if it was tailor-made for his new body. It felt exhilarating. He'd finally reached his ideal form, the epitome of Christmas.

It was difficult to concentrate on anything except masturbating. He was constantly horny, and even after his powerful orgasms, his cock often remained hard and he had to do it again. And again. And again.

He still took time to eat, though. That was important too. And he could do it while jacking off.

At the end of the day, Marco lay on his bed, content, still wearing his Santa outfit and contemplating the colorful Christmas lights he had in his room. Then, he turned his head to the polar bear figurine on his nightstand.

“Ahhh, this is perfect," he said to the figurine, who didn't reply. “I don't know if you're the one responsible for all of this, but… thank you anyway. I can't imagine this getting any better."

It almost seemed like the figurine was smiling.

Sunday, December 24th

Christmas Eve

When Marco woke up, he immediately noticed that the Santa outfit was… far too tight. He unfastened his belt, and his red coat opened to reveal that his silver-haired belly had grown even more.

“Fuck! No, no, no! It was perfect yesterday!"

It's not that he minded the extra weight, but he needed to fit in his coat! He stood up and tried moving around. Well… it wasn't that bad as long as he kept it open. It's not like there was anyone there to see his exposed torso.

He sighed. “Spending Christmas alone… That's sad…"

He looked at the bear figurine. He could swear its expression was different now, but he couldn't explain how.

First things first, though, he had to deal with his morning wood. As he was bringing his hand to his crotch, he paused for a moment. It seemed… different. The back of his hand was considerably hairy. He didn't remember it being that way. Also, his fingernails had grown quite a bit since the previous day. Well, as long as he was careful with those, it was alright. He shrugged, and started stroking his cock.

As he masturbated, he found himself being far more vocal than usual, grunting and growling like an animal. He even let out a powerful roar as he came, in one of his most intense orgasms ever.

He remained there for a while, panting, holding his throbbing cock and watching his cum drip through its length. Something didn't feel right. His new body was amazing, but he was all alone in his apartment, wasting his cum when he could be sharing it with others. Christmas was all about sharing!

He wanted to go out. He needed to go out.

But could he even go out like that? He didn't own any clothes that fit his current body other than his Santa outfit, and even that was getting too small for him!

Although… it was summer. He could leave his coat open, right? Besides, such a glorious belly deserved to be seen and admired by everyone.

Yes, it was okay.

More than okay, it was exactly the way it was meant to be.

But… something still wasn't right. Something was missing. He looked at the bear figurine.

“Not yet?"

The bear didn't say anything, but Marco felt like he knew what it was telling him.

“Not yet."

Marco growled. He felt so… confined in this small apartment. There was nothing he wanted more than to go out and spread the festive spirit to others. The immense happiness he felt, he needed to share it with the world! But if it wasn't the time yet… he could wait a bit longer…

But he was… so anxious… and so horny…

He jacked off a few more times. Watched a couple movies. Ate a lot of food. None of that seemed to calm him down. His hairy body was all hot and sweaty, but he never took off his outfit. He couldn't. It felt like part of him now.

Hours passed, and Marco waited. Impatiently, but he waited. And slowly, almost imperceptibly, his body continued changing.

His arms and legs were getting thicker, straining his outfit to the limit. The hair on the back of his hands continued to grow.

When he masturbated, he noticed that his cock now had a darker coloration. Almost black. In fact, most of his skin seemed to be darkening, although so much of it was covered in white hair that it was difficult to see.

As the sun set, he lay on his bed and took the bear figurine in his hand. No, not his hand. His claw. He understood it then.

“So this is what you wanted…"

He pressed the figurine against his furry chest, next to his heart. He was drenched in sweat, and his breathing was agitated. Illuminated by the Christmas lights in his room, he waited expectantly as the final steps of his transformation took place.

At that point, he didn't feel like watching a movie or eating anything. All his thoughts revolved around sex. He tried jacking off again. Sure, he got his orgasm eventually, but it didn't feel as fulfilling as before. His hand just wasn't enough anymore. He needed a proper hole to fuck. And not just one. As many as he could find.

“I need… I need to give…"

He screamed. He wasn't in pain. Not physical, at least. But the wait… the wait was agonizing. He dug his claws into his bed, tearing holes in the cum-stained sheets.

“Unfff…"

The fur on his chest and belly had grown so thick that it was impossible to see his skin underneath anymore, except on his prominent black nipples.

And his face… he couldn't see it, but he knew his face was changing too.

Standing while his body changed made him feel nauseous, so he continued lying on his bed. He stroked his perpetually-hard cock from time to time, even though he got no pleasure from doing so. He didn't know what else to do!

Marco looked at the figurine. “Please… Let me…"

Not yet. Just a little more.

“Arrrrrgghhhh!!!"

He masturbated furiously, but despite how hard he tried, he couldn't reach an orgasm anymore. Tears formed in his eyes. If he couldn't even do that…

Soon.

Soon he'd be free. And he'd be able to share the Christmas joy with everyone he came across. Yes. That's the only thing that mattered.

He screamed again as he felt his jaw elongating. He knew this had to happen. He was glad it was happening. But it still felt so weird.

Simultaneously, his tail started growing above his butt. It wasn't big, of course, but it grew with enough pressure to perforate his tight red pants.

After those two major changes, things finally seemed to slow down, until eventually, Marco felt stable enough to sit up on the edge of his bed. He was still panting and trembling, but he knew, deep down, that his transformation was complete at last.

Carefully, one step at a time, he walked to the bathroom and looked at his reflection in the mirror. If he thought he was unrecognizable before, that was nothing compared to what he was looking at now.

He was a bear. A literal polar bear. He was standing on two legs and he retained some basic human proportions, sure, but he wasn't human anymore. He was a bear.

He already knew, of course. He'd realized, hours ago, that this was where the changes to his body were leading to. But that didn't make it less surprising to look at. He was a fucking bear!

And a huge one, at that. He rubbed his massive belly, marveling at its size. He tried closing his red coat, but it was impossible. Well then, it'd stay open. His huge black cock was as erect as it had been for hours and leaking precum, but he didn't bother stroking it this time. He knew it wouldn't be enough.

He turned around and saw his cute tail crowning his enormous ass that pushed the fabric of his pants to the limit. He smiled. He also noticed that, despite having an ursine muzzle now, he still had what could only be called a beard. Very fitting, he thought.

Ecstatic, he ran back to his bedroom and looked at the bear figurine.

“Is it time? Can I go now?"

The figurine didn't reply. But Marco knew. He knew he was ready.

There was just one thing left to do, though. He went to the living room and found a big sack next to his couch. He didn't remember seeing it before, but he expected it to be there. He opened it and found it full of presents that all looked exactly like the one he'd received a week ago. Same size, same shape, same smell, same wrapping paper design. He smiled, having a pretty good idea of what was inside these presents.

On a hunch, he looked at the time. It was exactly midnight.

Monday, December 25th

Christmas Day

Marco opened the door to his apartment, carrying his sack of presents over his shoulder. A fresh breeze blew on his exposed furry torso. For modesty's sake, he'd shoved his cock inside his pants, but the massive bulge and wet spot left little doubt about its erect status.

Finally, his time had come.

It was Christmas.

He had a long night ahead, but this was what he'd been waiting for. This was his purpose. He was going to spread the festive joy through the entire city. He had a lot of love and a lot of cum to give. Not to mention the presents in his sack.

Soon, there would be many others like him. He wouldn't be alone anymore. And they'd all celebrate Christmas together, the way it was meant to be.

He sniffed the air, searching for his first target. His cock throbbed just thinking about what he planned to do. Marco grinned, unable to contain his excitement.

“Merry Christmas!!"
