Celestia's Weight Gain Experiment

The soft clang of a fine porcelain plate was heard in the dining room of Canterlot Castle. Atop it rested a heaping stack of pancakes that Princess Celestia had lovingly prepared. Steam wisped off its surface. Butter melted into the syrup and trickled down the sides. A proud smile made of ripe banana slices decorated the top, mirroring the gleeful expression of the Alicorn sitting in front of it. A rich fragrance met the mare’s nostrils as she inhaled deeply, savoring the first step on her sure path to fatness. With due grace, her glowing magic clasped a fork and knife at her sides, twirled them in the air, and deftly sank their edges into the stack of pancakes. A few quick cuts, and Celestia formed for herself a perfect morsel which harmoniously combined cake, whipped cream, syrup, and fruit. It practically glowed and sparkled as she held it aloft. At last, without inhibition or worry about the inevitable impact on her waistline, the Princess of the Sun took her first bite.

“Mmmmhhmmmmmm~~~ Hahahahahh!”

The graceful ruler of Equestria, in an instant, was reduced to an immature filly singing, laughing, and dancing in her chair.

“This is going to be so much FUN!”

She dug the knife and fork back into the stack, assembling bite after bite in a constant motion. Her jaw worked to chew the mouthful of calorie-packed wonderment, keeping a rhythm between swallowing and biting to ensure her grumbling stomach was filled as quickly as possible. Soft moans and happy gasps only slightly broke the pattern as Celestia embarked on her journey with gusto.

The happily chewing mare was prepared to keep eating until the plate was empty and her tummy was full, but she was interrupted by a golden door on the side of the room opening. In its frame stood Princess Luna.

“Mrphrm~ Heh~”

Celestia clumsily gulped down the fluffiness filling her cheeks so she could address her sister.

“Ah~ Good morning, Sister! Care to join me? I’ve made more than enough for the both of us!”

Luna ignored her Celestia’s goofy grin and spied the syrup and cream smattering her sister’s lips and chin. Clearly courtly etiquette hadn’t been a priority on this occasion.

“Oh, I have no doubt of that. Tell me: dost thou intend to make oneself a total sow every morning?”

Celestia grinned, taking it as a compliment and responding in a sing-song voice:

“Every~! Morning~!”

Luna scoffed and walked to the dining table, spying a basket of fresh, healthy fruit that had been utterly ignored by the table’s only occupant.

Celestia curtly added, “and every afternoon, evening, and night for that matter.”

Celestia punctuated her claim with another forkful of pancake jammed in her mouth and a theatrical shimmying of her shoulders. Luna retorted with her own, overly-dramatized twirl and toss of a bright, red apple before taking a generous bite.

“Good luck with that, piggy-corn. You do know ponies survive just fine on veggies and fruit.”

“We are sitting in a marble castle with golden doors. I think we’re slightly passed the ‘survival’ stage, dear Luna. Prosperity…”

Celestia took another bite of her far more opulent breakfast. Luna quietly looked at it with envy, knowing it was worlds more delicious than her modest snack. Truthfully, she was the last pony in Equestria who needed to count calories, and a single apple barely kept her stomach from rumbling.

“…ought to be enjoyed.”

Luna rolled her eyes and left the dining room, heading off to catch some sleep after a long night spent dream walking. She realized too late that she should have grabbed a second apple. Or maybe just one pancake. But there would be no end to the jests and sarcasm if she turned back now. She refused to indulge a pony so dead set on doing exactly that. Thus, she went to bed hungry…and a bit grumpier than she cared to admit.

Princess Celestia, on the other hoof, was quite the opposite. With her feast resumed, she made good progress on the stack of pancakes, making it at least two-thirds of the way through it before she began to feel full, and her pace slowed.

“Phew. Wow. These sure are filling. I suppose that is what I was going for.”

Celestia set the knife and fork back on the table, rubbing her tummy with a hoof. It was normal for her to quit eating when she felt contently full. As she glided her golden horseshoes across the concave swell of her stomach, the thought of discarding the leftovers and carrying on with her day entered her mind. It was fleeting. Today was not a regular day. Her eyes dropped to her belly, hooves making slow, circular motions across its surface. She noted how her fullness had turned her stomach into a pale, white orb that felt firm to the touch and covered the top of her thighs as she sat.

“Well, that is definitely how a belly should look. I suppose that’s what my belly will look like. But it’s…so small. It’s barely anything. And it isn’t even soft.”

She pressed her hoof into it, suddenly feeling the pressure intensify and then release as a loud burp that echoed in the room. Out of instinct she blurted an apology.

“Ah! Excuse me!”

Her eyes darted left and right. Nopony was there to hear her. And for once in her very long life, she had no reason to feel ashamed. Mercifully, the feeling of fullness subsided, and Celestia, with a devious grin and glutinous intent, slowly leaned forward, picked up the fork and knife, and continued eating. Her goal was to finish the plate, so that is what she was going to do. Breakfast is the most important meal of the day, is it not? Smacking lips, overly-stuffed groans, and occasional moans filled the room as her rhythm resumed.

By the end of it, the porcelain plate sat empty, and the mare in front of it sat filled to bursting. Her hooves again clasped the surface of the hard, distended protrusion in her lap. Her belly had grown a further two inches thanks to the last chunk of sugary cake painfully crammed inside of it. Celestia wondered if she had ever been this full in all her life. Her head fell back on the headrest as she rubbed and massaged herself, desperate to relieve the strain. Beads of sweat formed on her forehead as if she had exerted herself by the mere act of eating. She felt heavy in her seat and doubted she could stand, much less carry on with her duties.

“Ugh…this may be…slightly more challenging than I thought. Does this qualify as ‘going too crazy with it,’ or is this just what a not-yet-chubby pony must go through?”

She sat back up slightly, planting her forehooves atop the arm rests of her chair to lift and scooch her butt against the chair back. A few grunts left the bloated mare’s throat. She was heavy. Again, Celestia marveled at the expanse of rounded white coat filling her lap. Her belly button even looked stretched and distorted! Finally sitting more comfortably, she smiled and continued to explore herself. The belly rubs did ease the pain a bit.

“I suppose…like most things…it gets easier with practice.”
