>A fresh runnel of sweat sprung across Celestia’s brow.
>As her eyes drew down across her own body, she was met with the sight of folds upon folds; perspiration rolling along in steamy undulations that crested between the amorphous heaps of fat that might once have been called her hind legs.
>Mere moments ago this huge, reeking, clotted sack of flesh had not been there; the slight and gracious frame of an alicorn had burgeoned into a blimp stuffed with horse tallow.
>Her breathing hastened; it seemed that even the slightest movement brought on a bout of palpitating exhaustion.
>”Sister!
>The door to her chamber eased open, her smaller sibling’s muzzle rounding it curiously.
>As she was met with the sight of her sister blown up ten times the size, she drew back.
>Her features convulsed, and almost immediately her hoof fixed to her muzzle.
>”By the pillars, Sister! What in Eqqus has happened to you? That stench!”
>The stench to which Luna was referring was the feverish miasma of acrid body odor now swarming around the princess like a swath of pestilence.
>”Luna! Please! Don’t look upon me like this!”
>”Crack open a window, for Pony’s sake!”
>In the panic Celestia had forgotten what it was she was occupied by before this stark transformation had changed her.
>She turned her neck, as best she could, towards the clock on the wall.
>Only ten minutes until she was to give her speech.
>”Oh, my!”
>”Oh my is right! What caused you to... swell up like this, Sister? Some kind of arcane dark magic? A spell gone awry?”
>”It doesn’t matter! I’m supposed to be addressing the royal guards in mere moments! I cannot present myself like this!”
>”We should say so.”
>”My quill! Where is it?”
>She searched every inch of herself that she could, eyes scanning across the room and yet finding the quill was not in sight.
>”Luna! Sister! I need you to search for my quill!”
>”You want us to turn your room over all for the sake of one little-“
>”-Not my room! Me!”
>Luna froze momentarily, processing her sister’s request and finding it did not compute.
>”Surely, you jest.”
>”Do I look like I’m joking!? Hurry! We don’t have much time!”
>Luna clicked her tongue. Of all the things Celestia had ever asked her to do, this was was incontestably the most degrading.
>Still, her sister’s distress was clearly seen.
>Partly in how exhausted the mere act of panicking seemed to make her; her breaths laboured and her brow bursting with more sweat.
>”You owe us.”
>Luna approached - cautious, apprehensive, but knew this was something she had to endure.
>With a hesitant hoof she rolled away one of her sister’s flabby folds, disturbing the stagnant stench trapped beneath
>”Blegh! Must you punish our nose so?”
>”See anything?”
>”Nothing.”
>A cluster of air gathered somewhere in Celestia’s stomach and shot up through her gullet with the force of a rocket, realized in the form of a loud, stallion-sized belch.
>It sent a shower of spittle down over her sister.
>”Celestia!”
>”I apologize! It appears I no longer posses control over my bodily f- *uuuurph* -unctions!”
>”Perfect.”
>With a snide scoff Luna decided she’d had quite enough of peeling apart her sister’s fat rolls to search for a stupid old quill.
>”It is nowhere to be seen, lest our eyes deceive us.”
>Another memory regained fidelity in Celestia’s mind.
>”Oh! I remember where it was! On my stool!”
>”Your stool? Then, that means...”
>Luna glanced askance at the mountain of flesh hanging in two boulder-like cheeks that wobbled everytime the princess moved.
>”Not in one million years!”
>”Luna! Please! It must be stuck back there! I promise; once you retrieve it I shall never ask you to do something so humiliating again.”
>She took pause, and after taking a deep breath to steel herself (and immediately regretting the decision) the smaller - now MUCH smaller - royal sister rounded her sister’s titanic ass until she was behind her.
>Her cheeks lurched and squirmed, filled out to such a degree that they’d pressed firmly against each other, both dressed in a layer of sweat that only seemed to build by the second.
>”It might be... erm... between.”
>Of course.
>Luna reached forward to part her sister’s great flank, the sticky feeling of sweat against her hoof was enough to make her shudder.
>As the dank crevice caught between the two globes of fat was exposed, the stench in the room worsened to an almost uninhabitable degree.
>Even with her muzzle covered by her hoof, Luna could still smell the noxious poison given off by the puckering ponyhole and gently twitching ponut.
>The smell, Luna thought, was not unlike Froggy Bottom Bog in high summer.
>It was so foul she found herself dizzy and slightly disoriented, but the quill had to be found.
>”There is no sign of it, Sister!”
>”Oh, it has to be there somewhere! Are you’re sure you’re looking hard en-“
>She was interrupted by a deep, low gurgle that came from the depths of her guts.
>This was not a good sign.
>Luna could sense something was coming, but she was too slow to react.
>She watched in horror as her sister’s asshole opened to thicken and stir up the air with a rancid torrent of gas.
>It hit Luna right on, steaming her face with the sickening smell of rancid vegetation and ripened sulfur.
>There was a fleshy thud.
>”Luna!?”
>Celestia could not turn her neck.
>Trying to do so only brought another clap of ass-thunder rippling through her cheeks and catching some of the sweat that cling to them in a mist of fetid flatulence.
>She was unable to see that her younger sister was out cold.
