Celestia's Weight Gain Experiment

It can take some time to settle into a new routine. The first few days require particular focus, but with a bit of repetition, practice becomes habit. And so it was with Princess Celestia. Every morning, pancakes. A quick break from work for a heavy lunch. Ending the day with a decadent dinner. And with a bit of added effort, she finally managed to pile a slice of cake on top of it. Each moment the growing Alicorn felt the slightest hint of hunger was an opportunity to stuff herself even more. The first few days were defined by fullness, gaseous digestion, and cheerful savoring of her new ‘diet.’ Princess Luna grew increasingly frustrated with her deliberate, meager portions of fruit in the morning. Each time she snatched an apple, banana, or pineapple, she had to look over at her sister gorging herself on pristine, sweet-smelling confections that seemed to get more elaborately decorated each day. The smile of the glutinous mare signaled an impeccable self-satisfaction impervious to any snide or sarcastic comment Luna could muster. Goddesses, she wanted those pancakes. But the lanky blue mare knew what that entailed. Celestia’s stuffed belly was a sure promise of what was to come.

Raven was happy to see that her Princess had returned to her duties, but concern lingered. It was as if that first ‘sick day’ had altered something in Celestia. Not a single day went by where her stomach did not look filled to capacity. Raven mused that, by now, it must have become stretched, almost permanently swollen. Even though she surely could have skipped a meal or two at this rate, Celestia was at her most punctual when it came time for her to eat again. The results were glaringly obvious upon her return to work. And after a few days, Raven caught herself staring, whispering to herself as Celestia left the room:

“Has her cutie mark gotten bigger?”

She pondered this while eating a cupcake. It did not seem unusual at the time.

A full two weeks into her voracious eating habits, Celestia was amused by how difficult it was to skip a meal to take her measurements. Her stomach growled to be filled, even though she had been eating enough for three whole ponies to practically hibernate.

“Well, the ‘new diet’ is certainly starting to influence my thoughts and behavior. I find myself incapable of sitting down for a meal and not stuffing myself to capacity. I am barely even hungry when I eat my dessert either. It is completely recreational. Food has become a pastime, and ‘overly bloated’ is my new normal. The royal chefs have been excellent in their preparations and diligent in ensuring the portion sizes are larger than before. I have paid them my sincere compliments more times than I can count, and they seem quite pleased that I am enjoying their cooking. Though it may be time to ask for them to re-up the serving sizes.”

Celestia paused to inspect herself in the full-length mirror, pivoting in place to examine her butt and stomach more closely.

“I have been very attentive to how I look these days, and there is no denying it: my stomach is softer. I can feel it on my hoof and against my abs when I press against my skin. It’s not much, but there is a layer of flabbiness that certainly wasn’t there when I started. I must admit: it is very pleasing to the touch. I can imagine a typical mare being concerned about such a development or even being in denial. If I suck my stomach in, there really is no obvious difference. But to me, the sure confidence that this soft, cushy chub is only going to grow larger can best be described as curiously thrilling. I want more of it, and I am going to get more of it.”

She angled herself so her butt could be in her field of view as she wrote.

“Speaking of there being ‘more,’ this booty is getting outrageous. Since I am nowhere near the common descriptor of ‘chubby’ (let alone fat) I have become curvier and fuller than I have ever been in my entire life. When I last explored sexual relations with other mares, I found that big butts were very aesthetically pleasing and very fun in bed. I have heard of slang terms like “thick” to describe ponies with ample posteriors, but maybe I did not properly appreciate how such a phrase could come to be. Until now, that is. I am thick. The roundness of my ass compliments the curves of my legs and back, making me look incredibly fertile and inviting. I’ve noticed some of the royal guards and even my assistant Raven staring, though I do not address it. Raven seems to have taken a liking to treats that I cannot quite explain. I can guarantee my castle staff find me more attractive than usual. If even I am admiring something, I am certain it is worth a second look for the average pony.”

With a certain amount of trepidation and a deep, calming sigh, Celestia climbed onto her scale.

+6 pounds since last measurement; +6 pounds total

“HAHA! That’s right! Weight gain! Actual, serious, weight GAIN!”

Celestia’s hooves clopped happily and her wings fluttered as she pranced in place, celebrating the first of what was sure to be many milestones. As she moved, she could almost swear she felt her added softness jiggle. She marked the progress on her graph and returned to her notebook.

“It’s happening. I mean, I knew it would. But the fact of it. How amazing! How incredible! Literally any pony in Equestria has this option, at any point. If they just eat way too much, they grow. They get bigger. And now it’s me! I’m the one getting chubby! And to think: this is just the start!”

Her chuckles subsided and her smile faded.

“As a final note, I am fairly certain this is related to my recent change in habits, but Luna has been looking very gaunt. She has bags under her eyes most mornings and seems grumpier than usual. I offer to share my pancakes with her, but that only seems to agitate her more. I know I was (mostly) kidding when I brought it up with her the first time, but that pony could seriously use some extra pounds. And maybe a few more on top of that, but shhhhhhh~ I don’t need to go that far.”

Celestia gave a wiggle of her thickened behind in the mirror to put herself back in a good mood. And with another mighty growl of her stomach, she trotted off to her next, extra fattening meal, very pleased with herself.

“No reason to stop now. Chubby phase, here I come!”
