Celestia weight gain (complete version)

chapter 8

Two weeks had passed, with Celestia’s routine unchanged, feasting constantly unless there was politics to attend to.

And it showed. Sweet Celestia did it show.

Celestia’s wings and hooves spread out in every direction, comically inept and tiny in comparison to a belly that covered the floor in front of her and two titanic ass cheeks sprawling off behind her. Her neck now hung and spread across the top of her belly, and one could scarcely tell where one chin ended and another began until finally reaching the one muscle still burning calories: her mouth. Celestia chewed and swallowed, shoveled more treats into her mouth, and chewed and swallowed again. She scarcely left the catatonic, drug-like state that had so perplexed her at the start, and after so long caught in this rhythm, she even ate in her sleep.

The royal chefs – their staff expanding almost as quickly as their client – had stopped bothering to cover the dining table, and instead opted to make continuing trips from kitchen to blubbery Princess, making different treats each time. Some found a competition amongst themselves to see who could make Celestia moan especially hard or remark upon what was especially delicious. Other than that, little was preoccupying them besides maintaining a constant deluge of sugary, fattening treats for their ruler to enjoy.

Luna visited her sister in the dining hall often, always noticing how Celestia’s belly spread a little bit wider, or how her head was propped up a little bit further by her ever-expanding ‘chair’. She found herself so drastically outpaced by her sister’s gluttony, so captivated by it, that she began to relapse, wondering every now and then if her butt was actually as big as her sister’s once was. And either out of self-consciousness or, as Celestia suspected, a repressed jealousy, Luna would occasionally join Celestia’s feast.

For Luna, the effects of the past weeks were far more obvious than for the growing ball of blubber her sister had become. She had been skinnier than her sister even before she began her gluttony, and now, it was quite clear that she had grown far fatter than her sister had ever been. Her supple blue coat now covered an ample pot-belly, and her ass – once a source of insecurity for the Princess of the Night – now dwarfed that of any pony in Equestria. The crescent moons and ink-black spot under her tail now filled the dining room chairs as her sister’s once had. And on this day, as she worked her way through the second strawberry cheesecake of her third lunch, she craned her neck and ran her hoof along her black collar. It felt tight.

“Sister?”

Celestia barely mumbled back as her magical grasp alternated between a tray of chocolate eclairs, a platter of mini lemon tarts, and a ladle of thick chocolate milk.

“Hmmm?”
“Does my collar look small to you?”

The question snapped Celestia back to reality for the first time in what must have been several days. She counted herself overworked enough just raising and lowering the sun in between meals. But with the promise of such a delectable sign of her sister’s poor self-control, she peered down over her massive belly – finally aware that her fat had made herself taller than she had been on her own four hooves – to see the adorable sight of Luna struggling to adjust her jewel-encrusted yoke over a chubby neck that bulged at the top and bottom.

What’s more: Celestia could see that Luna’s butt was filling her chair. Her bony backside seemed a distant memory compared to the dark, luscious flanks squeezed into the tiny seat. Luna’s pot-belly, properly stuffed, pressed against the edge of the dining table, a rather substantial roll of fat flowing onto the table’s wooden surface. Atop Luna’s budging neck were a pair of chubby cheeks and a set of lovely, little dimples to meet them.

“Do you remember when you came home from your trip?”
“Yeah.”
“And you could barely believe how fat I had gotten? I believe you used the phrase...‘the physique of a small hippopotamus’?”
“Yes, of course, your point?”
“That’s what you look like right now.”

Luna stopped struggling with her collar, looked up at her big – and an emphasis on the BIG – sister, smiled, and grabbed the yoke with her magic, removing it and tossing it across the table with a loud, metallic clanking sound.
Celestia started to chuckle. Then Luna. Before long, the dining hall was alive with howling laughter as the two princesses bounced and jiggled with glee.

“Good heavens, I haven’t laughed like that in years. Am I really that fat?”
“From where I’m looking, you’re actually as skinny as a medium-sized hippo. Now eat up before you starve to death!”
“Heh...I must admit, sister, I haven’t been truly honest with you. About a week ago, I did notice I was getting chubby. First it was just a little bit of extra flub around the edges. I rationalized it as ‘oh, well, my butt still isn’t as big as her’s was!’ But with you doing...whatever glutenous marathon this is supposed to be...I kinda lost my reference point. I stopped thinking about your physique back then and kept returning to thoughts of what it had become. The little bits of flub grew, gradually, but undeniably. Then, I woke up one morning and it...wasn’t little anymore. I had a belly, and a butt! I thought I would be scared. I thought I would feel gross or guilty. But then...”

Luna gripped her chub as her sister had done, caressing and feeling every roll and fold.

“I felt soft.”
“Feels good doesn’t it?”
“The most amazing feeling in the world. It’s like being hugged by pillows on all sides, but you are also the pillows hugging you. I couldn’t have imagined what it would feel like to actually be fat. The bigger I got, the more sensual the feeling became, and the more natural it was to keep growing. And the food, sweet stars above, the food!”

Luna bit off a mouthful of her cheesecake, exclaiming through her full cheeks:

“Delicious!”
“Indeed!”
Celestia picked up a decadent mousse cake, drifted it over to her mouth, and started taking large, noisy chomps out of it, smearing frosting all over her blubbery face. Luna drilled her mouth into the creamy cake in front of her, her belly pushing against the table, folding and blossoming against it. The once-petite Princess of the Night pounced at the opportunity to ignore etiquette and chow down like the slob she had become. After a few moments of primordial moaning and chewing, Celestia broke the spell.

“Luna?”

Her thickening blueberry of a sister took a breath and absent-mindedly wiped her mouth with a hoof.

“Yeah?”

“What makes you think I can still stand up at this point?”

Luna blushed before picking up a pitcher holding a thick, caramel-infused vanilla milkshake to wash down her cheesecake. She began to drink, letting her sister speak.

“I haven’t been able to stand for days, if not weeks. Just look at me. I’m so fat, I can barely see your fat flanks filling that chair over this gut of mine.”

Luna chugged the milkshake, her fat swelling with every gulp as her alicorn metabolism desperately stored the excess calories entering her stomach. The dining chair creaked and scooted backwards as her belly – soft though it was – pushed against the table’s edge.

Celestia blurted out the words as soon as they came to her, as if to encourage Luna to keep drinking as she spoke.

“You thought it was bad when I used my ass as a bean bag chair? I’m basically one big, blubbery marshmallow at this point! You think you’re soft? I am a living cloud, and I just keep getting bigger! I can feel every inch of me growing at all times. I eat so much food I can’t remember the last time I felt hungry. I’m getting taller because my ass-fat is literally pushing my head upwards. If I keep at this, my belly will push the dining table against the wall! And once that happens, my butt will just grow the other way into the opposite wall! When I started, I thought a little bit of chub would be enough to stop me. Now, I can’t wait to fill this room!”

Celestia slapped her belly with a large strike of magic, and her entire mass shook from the impact, she winced and moaned with orgasmic bliss feeling so much of herself move at once. Even at this size, her marehood could tingle. And apparently, she was not the only one.

Luna finished the tall pitcher of cold milk and ice cream, letting out a proud burp. Even with the chilled drink filling her stomach, her face was flush with arousal. In the short time it took Celestia to finish her ranting, Luna’s butt had grown painfully tight in her chair, just as stuck as her sister’s had been. The soft, cathartic pain of her full, bloated stomach straining to contain the mass of calories she had ingested, along with her sister’s imaginative descriptions of growing fatter than any pony in history sent Luna careening over an edge she didn’t know she had remaining. After several heaving breaths, she finally gasped:

“Could you even stand when I offered that compromise two weeks ago?”

Celestia let out a knowing chuckle.

“Luna, I haven’t been entirely honest with you.”

Luna grinned widely, recognizing the implication. Her chubby cheeks parted to beam an elated, knowing smile across the table and over her sister’s enormous belly.

“From the moment I plopped down on my ass that day, I haven’t even tried to stand up!”
“Well in that case, you want to fill the room, Sunbutt?! It’ll be quicker with a second obese pony here to take up space!”

Fully succumbing to her glutenous bliss, Luna levitated yet another slice from yet another cake over to her mouth and took a bite.

Just then, her chair collapsed.

A weighty thud echoed through the dining hall as Luna’s butt hit the floor. A stunned silence was replaced by joyous laughter as the two fattest sisters in Equestria recommenced their feast.

And with that, Princess Luna and Princess Celestia never went hungry again.

The end.
