The soft glow of firelight kissed the rough-hewn logs of a small wooden cabin, stirring them from a deep, dreamless sleep. Outside, a gentle whoosh and whisper hinted at a world swallowed by snow, a stark contrast to the cozy warmth that enveloped them. Blinking, they took in the spacious room: a stone hearth crackled merrily, a sturdy table stood laden with unidentifiable cooking implements, and a plush rug covered the floor. Then, their gaze snagged on something large, utterly colossal.

It was... well, was that an exercise ball? No, the sheer scale of it, the rich, mahogany-brown fur, the slight twitch of a tail… it was the backside of a reindeer. A truly, extraordinarily fat one, to be exact. Her plump, rotund rear end seemed to take up a significant portion of the kitchen space as she hunched over a stove, where what looked suspiciously like a golden-brown turkey sizzled.

Suddenly, the massive reindeer rotated, her head turning to reveal a kind, whiskered face framed by a soft, fur-lined hood. Her deep brown eyes, warm as cocoa, widened in recognition. A wide, sweet smile spread across her snout. "Well, hello there, dear! Look who's finally awake!"

With a soft chuckle, she began to make her way across the room. Her large, rotund body swayed with each step, a gentle slosh and gurgle accompanying her movement as her substantial gut jiggled. Reaching the bedside, she knelt, her voice a mellow, soothing balm. "Found you out in the snow all by yourself. You were quite passed out, so I took the liberty of bringing you here with me. Oh, and by the way, welcome to the North Pole, sweet pea!"

She clapped her immense hooves together with a soft thump. "I'm making a grand feast just for a special guest like you! Don't get too many visitors way out here on the Pole, so I'm going all out!" Her tone was sweet, yet held a hint of playful sarcasm.

True to her word, about thirty minutes later, a small, sturdy table was pulled up right beside the bed, laden with steaming plates. Dasher, as she introduced herself with a wink, began to spoon generous helpings onto a plate, her gaze full of indulgent approval. "Eat up, sweetie. You look like you could use some meat on those bones."

The first bite was a revelation. It was turkey, yes, but unlike any turkey they’d ever tasted – rich, succulent, bursting with flavors that danced on the tongue. Side dishes followed: creamy mashed potatoes, sweet cranberry sauce, glazed carrots that melted like butter. Each mouthful was pure bliss, an overwhelming sensation of comfort and decadent pleasure. The world outside the cabin, even the fact of where they were, faded into an ethereal haze as they ate, guided by Dasher's gentle encouragement, lost in a delicious, dream-like trance.

Two hours later, a soft, contented groan escaped them, jarring them out of their food-induced stupor. They blinked, the firelight seeming brighter now, the cabin walls more solid. And then, they looked down. Their eyes widened.

Their stomach. It wasn't just full; it was a gigantic, swollen ball, taut and round like a tightly inflated yoga ball, straining against their clothing. Or rather, what was left of their clothing. Their shirt, stretched past its limit, had ridden up, revealing the vast, distended expanse of their belly. They hadn't even realized Dasher must have changed them into something more comfortable – though it clearly wasn't comfortable enough now. A deep blush crept up their neck as they registered the immense, bulging orb that was their new midsection.

As if on cue, the floorboards creaked. Dasher, her hooded head tilted playfully, was approaching. In her massive hooves, she carried not a plate, but a cauldron. A huge, frothing cauldron, swirling with what looked to be a thick, creamy milkshake. Her sweet eyes twinkled with a hint of mischievous anticipation. "Don't tell me you're full already, dear? We still have dessert! Better make room in that big, fat belly of yours… quickly, now!"
