It's Christmas Day, and for Shinespark, that means taking a break from his job of wish-granting. The reality-rewriting rabbit doesn't have anything festive on his agenda, but a visit from a rather jolly saint might convince him to open his schedule...

This is a (belated) Christmas gift from me to you all. January 31, 2025 was when I posted my first story here on FurAffinity, and revealed my furry self to the world at large. Since then, I've made a bunch of friends, learned to be more open and accepting regarding my kinks, and amassed a following that I never thought someone like me could achieve.

To everyone who watches me here.
To my followers on Bluesky.
To everyone who's made art and stories for me, no matter the reason.
To those of you who interact with my posts on any website in any way.
To anyone who views the stories I write and the art I commission.
And to my buddies on Discord.
I hope you all have a wonderful rest of your year.

But enough with the sappy stuff. You came here to read about my bunny boy getting fat, right?

Today was December 25th, and across the multiverse, people were sharing gifts and good company. Shinespark knew it as Christmas, but the holiday seemed to have a different name and reason for existing in every universe. Why the date seemed to remain constant was a mystery to him, though.

The blue and white-furred bunny wasn't complaining, though. Since everyone used this time to check items off their buddies' wish lists, it gave the reality rewriter a chance to take a break from his own job. Shinespark invited folks to his pocket universe to grant their wishes every single day. As much as he loved his profession, it only seemed fair that he got at least one vacation day a year.

As for what he was doing with his time off? Relaxing, mostly. He wasn't really the kind of guy to celebrate the holidays, especially since there wasn't anyone else in his home for him to celebrate with. So, for now, he stayed in his bedroom. He was wrapped under the covers of his bed, cuddling with a collection of blankets and plush toys.

His snuggle time came to an abrupt end when he heard a sudden noise.

*jingle jingle*

[Were those... sleigh bells?] Shinespark thought. [It sounds like they're in my office…]

The bunny jumped out of bed, revealing his chubby physique as well as his yellow-colored pawpads and inner ears. He made his way to his office, the room he used to talk with visitors and work out wishes for them. When he stepped inside, however, he didn't find his desk, bookshelf, and guest chair.

The place had somehow been transformed into an incredibly festive living room. All sorts of winter and Christmas-themed touches had been applied. The walls looked like they'd been covered in wrapping paper. The white carpet resembled a coating of snow, but felt incredibly soft and warm on Shinespark's paws. On one side of the room was a Christmas tree with a small gift box underneath it, ornately decorated with lights and baubles. A lit fireplace was embedded into a wall on the opposite side, with two stockings hanging off the mantle. Both of them were marked with the letters "S.S."

Finally, there were two wooden rocking chairs with soft red cushions on them in front of the fireplace. To the bun's shock, one of them was occupied by a rather portly polar bear with a thick white beard. He was wearing the red and white regalia of Santa Claus, hat and all.

The visitor noticed Shinespark's presence and turned to face him. "Ho-ho-ho! Merry Christmas, my fellow wish granter!" His voice was deep and jolly, just like most of his depictions in movies and TV.

"S-S-Santa?!" The rabbit stuttered out of nervousness and shock, but quickly regained his composure. "You're real?"

"I'm as real as you are, Shinespark," the polar bear confirmed. "This isn't a Coke commercial, ho-ho! I'd never stoop to using generative AI for my job!"

"Hah, neither would I," the bunny chuckled. "But... why are you here?"

"How about you have a seat next to me, here by the fire, and I'll tell you?" Santa replied, motioning towards the other rocking chair. "Oh, and you can call me Nick or Kris if you like."

"Hmm... what if I called you Scott?" Shinespark suggested in jest as he sat down.

"I'd have to put you on the naughty list if you did!" Kris joked back.

The two shared a laugh, the rabbit letting out 'ha's and the ursine bellowing 'ho's.

Once they calmed down, St. Nick turned to Shinespark. "You've been very nice this year," he said, before switching to a serious tone. "When you gained your abilities last November, I feared for the worst. A lot of people in your position would perform foolish, greedy, selfish, or destructive acts. They would go mad with power, not thinking or caring about the consequences of their actions."

"But I never planned to do any of that," the rabbit commented.

"Ho-ho-ho, that's exactly why I'm here!" Santa exclaimed. "You have such a strong moral compass, Shinespark, that I quickly realized I shouldn't have been concerned at all! So, from one wish-granter to another, I would like to give you a special gift."

The polar bear snapped his fingers, which somehow sounded like a ringing sleigh bell. Both rocking chairs jumped into the air, did a 180 to face the festivized tree, and landed safely.

"Whoa, that was neat," Shinespark said. "Christmas magic?"

"Indeed!" Kris Kringle pointed to the tree that now stood in front of them. "Under this tree is your reward for being one of the nicest folks on the nice list! And yes, I checked it twice!"

"Gosh, thank you!" Shinespark told Santa as he approached his present. It was a small, square box painted to look like it was encased in wrapping paper and ribbons. The top was detachable, so the bun popped it off to reveal…

"A cup of hot chocolate?"

Within the box was a simple white coffee mug filled with hot cocoa. Not mere chocolate milk - faint steam was coming off of the liquid, and a couple of marshmallows were floating within it.

"Looks can deceive, Shinespark," Nick chimed in. "Give it a sip. I'm sure you'll enjoy it!"

"Alright," the rabbit said, taking the mug out of the box. He brought it to his lips and took a sip.

A smile spread across his muzzle. This was the best hot chocolate he'd ever had! It was rich, yet smooth; hot, but not to the point where it would burn. He plucked out the marshmallows and tossed them into his mouth. They were pillowy-soft, and had just the right amount of sweetness. Shinespark savored his time chewing them, then eventually swallowed so he could get back to the cocoa.

The bunny slowly emptied the mug of its ambrosia over the course of a few minutes. It felt like pure, melted chocolate was flowing through his mouth and down his throat every time he took a gulp. As much as he wanted to enjoy this experience forever, the hot chocolate eventually ran out.

"Mmm..." Shinespark rubbed his belly with one paw. He could still feel the warmth from the drink inside him. Using his other paw, he placed the cup back inside the gift box. "Compliments to the chef," the rabbit said, turning towards the polar bear with a smile. "That was wonderful!"

"Don't thank me yet!" Santa teased. "You haven't fully experienced your gift!"

"Huh?" The bun reacted with confusion. Did Old Saint Nick have something else up his sleeve?

It was then that Shinespark noticed the warmth from his stomach spreading to the rest of his body. His torso, his arms, his legs, his paws, and his head eventually felt that increase in temperature. It was a pleasant, cozy feeling, one that reminded the rabbit of when he'd been snuggling in bed earlier. He couldn't help but wrap his arms around his chubby belly and give himself a hug.

Except, to his surprise, his arms collided with his tummy sooner than he expected.

Shinespark looked down. His small potbelly had grown into a larger, fatter gut. Not only that, but he could see his entire body slowly expanding with flab. Legs bloated, arms sagged, moobs grew, love handles materialized... Taking a look at his rear end, he could confirm that his butt was caking up, too.

This wasn't anything new to the bunny, of course. He loved to use his powers during his free time to give himself some temporary bulk. But this warmth... He'd never felt anything like it! Despite his increasing size, his temperature remained constant. Not only was he not sweating, he felt more and more comfortable as he fattened.

Shinespark's belly now stuck out a full foot in front of him and sagged down to his knees. His moobs had grown to grapefruit size, and his arms looked even larger than the Michelin Man's. A ring of neck flab served to cushion his pudgy-cheeked, double-chinned head. His wide love handles ensured that he'd have problems with doorways. A cascade of back fat led down to two very round, very plump buttcheeks.

The bunny's upsizing stopped there. Not that he minded; he adored being this fat. Warmth still enveloped him in what felt like a full-body hug. He couldn't stop himself from playing with his fat folds. He just felt so soft, so squishy, so cuddly!

Then Shinespark remembered that he had an audience.

"Crud! Uh, you didn't see that!" the rabbit panicked. He adopted an innocent pose, clasping his paws together near his enlarged belly and giving a sheepish smile.

"Ho-ho-ho!" Kris Kringle looked more amused than anything. "No need to be embarrassed, Shinespark. I already know of your more... niche interests. Why else would I give you a gift that plays into them?"

The bun mentally slapped himself in the face for not realizing sooner. "So, the hot chocolate..."

"I imbued no small amount of Christmas magic into it," the polar ursine stated. "But even now, its job isn't done!"

"There's more?!"

Right on cue, Shinespark's stomach let out a loud gurgle. A few seconds later, he felt as if two groups of invisible hands had grabbed onto either side of his fat body and started pulling.

"W-what is happening?!" The experience didn't feel painful for the pudgeball of a rabbit, but it certainly felt strange.

"I wanted to give you an experience you've never had before - one that I know you'll love," St. Nick explained. "The setup might feel weird, but the result should be more than worth it!"

[Understatement of the century!] Shinespark thought. [It feels like I'm being torn in two!]

Yet he still felt no pain. In fact, as the hands pulled harder, he suddenly felt the presence of another, identical consciousness in his mind. It was then that he realized something crucial. He wasn't being torn in two - he was being split into two!

The phantom hands gave one final, massive tug, and from a single fat bunny, two emerged.

Both Shinesparks were knocked onto their oversized rears, their bodies wobbling from the impact. Neither of them were injured, but it did take a bit for them to stand up.

As soon as they recovered, both buns raised one of their arms and pointed their index fingers at each other. They yelled in unison, "My own clone! Now neither of us will be vir-"

*ahem*

The two were interrupted by Santa before they could finish reenacting two memes at once. "Keep things family-friendly around me, please," the polar bear requested.

"Okay..." one of the Shinesparks lamented. "Sorry, Father Christmas."

"Right, because the two of us being massively obese is perfect family viewing material," the other Shinespark snarked. He then asked Santa, "How does this work, anyway?"

"Yeah, how long are we gonna be two people instead of one?"

"And should I be referring to both of us as singular or plural?"

"How you refer to yourself, or yourselves, is up to you," Santa stated. "Both the weight and the duplication will last until the very end of the year. Oh, and I threw in a little bonus: you can feel everything your counterpart feels!"

Both bunnies went wide-eyed at the last bit of news. "If that's true," one of them said, "then we gotta give each other a hug!"

"Yeah, let's do it!"

The two big buns waddled towards each other and leaned in close, wrapping their chunky arms around their other self as best they could. What they experienced was nothing short of electric. Each Shinespark felt the plush softness of both of their fattened selves at once, and it felt wonderful! They were cuddling and being cuddled, their nerves receiving double the stimulation. It wasn't overwhelming at all - only comforting. Combined with the full-body warmth from the hot chocolate, they both felt so cozy that they never wanted to leave each other's grasp!

"Ho-ho, I'm glad you're enjoying yourselves!" Santa chimed in. "But I need your attention for just one more moment."

The dual blubberbuns reluctantly broke from their hug and turned to face the polar bear.

"I have to return to the North Pole now," Kris said. "I'll bet Mrs. Claus and the elves are worried sick about me. I don't usually deliver gifts outside of Christmas Eve, after all."

"Thank you so much for everything you did for us today," one of the Shinesparks said.

"You're very welcome." The ursine lifted a paw. "Merry Christmas to all, and to all a good night!"

With another sleigh bell-sounding finger snap, Santa Claus disappeared. With Father Christmas no longer present, Shinespark's office instantly returned to normal.

"Well, I wasn't planning on any of this happening," one of the Shinesparks said. "But we had a rather festive time, didn't we?"

"Why should the festivities end here?" the other fat rabbit responded with a grin.

His counterpart gave a soft smile, and the two embraced each other once again.
