Nightmare Moon's Rubenesque Revenge

The sound of applause rang through Ponyville. After the traumatic events of the night, order had been restored to Equestria. The sun shone in the sky, casting its warm rays across the landscape, glinting off spotless windows and glossy balloons alike. Music drifted through the streets as streamers and confetti drifted from the skies above. It was a proper Pinkie Pie party, with both refreshment and merriment in good supply.

“Well, I’m sure glad that’s all over. I think I’m just about beat!” Applejack smiled, looking across at the group of ponies she’d gotten far closer too. All of them were relieved, happy that the whole Nightmare problem had been dealt with. Still though, after a night of adventuring through the dangers of the Everfree, the sight that had greeted them at the end was… difficult to shake. Almost unanimously, they’d decided to clam up about the whole thing, the only exception possibly being Pinkie… one of the few who hadn’t looked utterly horrified.

Twilight, on the other hand, looked far worse for wear than the others, trying to keep a straight face. “Say Twilight, what’s the matter?”

Twilight jumped at her question, sighing as she walked over. “Well… quite a lot of things, to be honest. As you’ve probably realised, I’m not exactly the most sociable of mares. This whole experience has really opened my eyes to the world around me, and the value that friendship has. You, and everypony else means a lot to me, and now my task in Ponyville is finished… well, I’m going to be heading back to Canterlot.”

“Send you back? Darling, I may not know too much about… Celes… the Princess. But I know she’s a very kind mare. You were sent to Ponyville to make friends? It would be rather harsh just to send you back there by yourself, I’m sure she won’t just take you away.”

“Are… are you girls sure?”

“Sure as the Wonderbolts are cool!” Rainbow Dash shouted, earning a few chuckles and eye rolls. Twilight’s expression lightened, but still wasn’t a full smile.

“Let me guess sugar cube, it’s Celestia herself?”

“How could I not? I’ve known her for years, and in all that time, she always had a level of control, always had a grasp on any situation. Then the one day she disappears, she ends up becoming… massive. After the elements hit her and the Nightmare, she looked really out of it. I hope she feels alright.”

“Um… well Twilight, I don’t think you’ll have to wait long.” Fluttershy broke in, gesturing with a hand towards a large group of guards pushing their way into the crowd. Forming two lines, they cleared the entire road, practically clearing most of the town square, very much to the indignation of the party goers. Slowly, the sounds of partying diminished, everyponies attention drawn to the street. A cart, apparently made from several heavy goods carts haphazardly welded together, trundled into view. At least a dozen well-built stallions were hitched to the front, their bulging muscles straining to move the buggy any faster than walking speed. On the back of the absurd contraption, Celestia, still looking like an immense dollop of partially melted vanilla ice cream.

Her form had been partially clothed, with a bra/top made from several tablecloths wrapped around her upper torso, offering a very slight bit of decency, though offset by the twin mountains her ass had ballooned into. Her entire building-sized body jiggled and wobbled where she sat, creating a rather hypnotic dance of flesh as it slapped and smacked together, producing juicy claps with every impact. Ever with the Frankenstein cart, it still wasn’t quite big enough to hold the blimp of blubber, as great folds and rolls oozed over the sides like bread rising in a tin. Celestia’s head wasn’t even visible from where most ponies stood, only catching a glimpse of her ethereal mane billowing out with the wind.

So occupied with the gargantuan mass Celestia was, one could easily miss the tiny carriage pulled beside Celestia’s, a rather pensive and guilty looking Luna sitting inside, trying to avoid eye contact with everyone, and trying especially hard to look away from her sister. Stopping in the middle of the square, an uneasy silence filled the air. Suddenly, Twilight felt magic wrap around her body, lifting her into the air and towards the top of the blob. Simultaneously, the rest of the Mane 6, Luna and Spike were lifted up, carefully placed around her head.

“P… princess. Are you… are you ok?” Twilight nervously broke in, simultaneously setting off a great number of whispers, Spike being amongst them.

“Wait… we’re standing on Celestia? How… how did she get so big?” He mused, poking and prodding the swell of fat he was currently sitting on.

“Yes Twilight, I’m more than fine. I’ll admit, I’m still a little woozy from the Nightmare’s magic, but I’m feeling much more like myself now. My weight gain doesn't look too noticeable, does it?” Celestia grinned, winking knowingly.

“But Sister, thou art so large! This is our fault, is it not? We must try to find…” Luna spoke up, her grief-stricken voice cut off.

“No, Luna. I already told you… this isn’t your fault. You’ve been a prisoner of your own body, the Nightmare hijacking and corrupting everything good inside. The actions are those of the Nightmare, not of your own. Besides, I must confess that I’m very much enjoying this new form.” Silence again, broken by Twilight stammering.

“What… Princess, you can’t be serious. How can you like being this… fat.” A light titter left Celestia’s lips, jiggling her form slightly.

“I know this may be hard to believe Twilight, but I’ve never fully been happy with my body. I suppose you’ve seen in the tabloids about my eating habits. As tacky as those things are, they aren’t false by any means. I’ve always liked to indulge, though far less than I’d like. I’ve always needed to keep up a trim figure, lest Kibitz and the others get on my case. Now… I finally feel like I can let loose and enjoy myself.”

“But Sister, thou art the size of a leviathan, how does one expect to rule in such a condition?”

“I’ll find a way Sister.” She said with finality, confidence filling her words, just as the deep, bassy rumble of her belly cut in. “We’ll finish this conversation later… I’m feeling rather ravenous now, does anypony know where I can get some cake?”

“Ooh! I know exactly where, Princess!” Pinkie piped up with enthusiasm, her own smile matching the Princess’s greedy one.

“Excellent. For starters, I’ll need around a dozen assorted cakes, at least birthday cake sized please. I think that may just take the edge off my hunger…”
