Chapter 1- Sunbutt's Booboo
Once upon a time, Princess Sunbutt actually did things. She fought villains, killed monsters and-
"What kind of story is this?", Sunbutt shouted at her sister Moonbib.
"Just let me tell the story!", Moonbib shouted back.
Princess Sunbutt made a face and shunned her sister. She obviously knew what her sister was trying to do. Princess Sunbutt didn't want to be hard working. She liked being a fat, lazy, inconsiderate slob. She enjoyed laying in bed with no care in the world. Princess Moonbib however, was determined to prove to Equestria that she wasn't the hypocritical serial killer politician they all thought her to be.
"Tell me a better story!", commanded Sunbutt.
"Fine", Moonbib groaned, "One day there was a Princess who didn't need to do anything but look pretty because she was royalty. The End".
Even though Sunbutt enjoyed being a fat slob, she adored Moonbib's sweet curves. This was the only reason she raised the sun everyday. She wanted to maintain such a figure. Unfortunately, constant binge eating while depressed (which happened often) caused her to gain the lumps of an elephant around her thighs. This is why she only presents herself to the peasants in the day, after raising the sun; she wasn't fat then.
As Sunbutt drifted off to sleep last night, she dreamed of having a sexy bod like Moonbib's, but she also dreamed of the effort it would take to do so and how she would devour all the kitchen's food out of depression at the speed of light the next day.
Urrrrrrrrrrghhhhh..., Sunbutt groans as her fats spill off the mattress, How is it even possible I grew fatter while sleeping. It doesn't even work that way!
Sunbutt sits in bed, moaning at how horribly her fat stretched and furthermore, how horrible her day was going to get. All of a sudden, a cunning plan flashed into her head. Just at that moment, princess Moonbib entered the room screaming, "WAKE UP!", in her Royal Canterlot Voice; knocking even the whale-like Sunbutt off her bed.
Sunbutt's huge, unappealing thighs jiggled as she scrambled across the floor, staining it's surface with sleep sweat. "I'm awake!", she said as she struggled to get up much like a tortoise on it's shell; a fat one, for that matter. Going through the devious plan once more, she managed to roll herself up and stand on her hooves (which, I might add, could barely support her weight).
"OHHHH! MERCY, MERCY, MERCY ON MY POOR ROYAL SOUL!", Sunbutt moaned heavily.
Moonbib stared confusedly (and slightly disgusted) at the white, blobby alicorn. "What's wrong?", she asked politely for fear that she might lose her head; even though the answer was quite obvious (If you know what I mean).
"MY POOR ROYAL BACK IS KILLING ME".
"Uhm... Well, I'm not surprised", Moonbib chuckled.
Ignoring the comment, Sunbutt said, "I CAN'T EVEN MOVE MY ROYAL HOOVES". She wriggled dramatically on the ground, making her appearance even more revolting.
"You never could, anyway...", Moonbib rolled her eyes.
The plan was failing, she needed some way to convince Moonbib that she was really, truly hurt.
"Hurry up, Sunbutt, you're already late to raising the sun!", Moonbib exclaimed as Sunbutt groaned, "Move thine white ass!".
Sunbutt's bottom lip quivered pathetically, almost as much as her fat did. It wobbled for another five minutes as she was unable to stop herself. "Alright, alright, what do you want...", Moonbib asked in annoyance in order to stop her sister's hopeless jiggling.
Hope arose in Sunbutt's eyes, "Can you pwease raise the sun fow meeeee?", she asked trying her best to look cute. Unfortunately, it caused her neck to form a quadruple chin.
Repulsed, Moonbib shouted, "ALRIGHT. Alright. Just please... don't do that again *shudder*".
Sunbutt jumped with glee, her fat bouncing along with her movements.
Suddenly, a terrifying thought entered Moonbib's mind. Her eyes grew wide in utter shock. "NO, NO, NO, NO, NO. YOU HAVE TO RAISE THE SUN, SUNBUTT".
Sunbutt's happy dance turned to a frown, "Why not?!".
"Every. Single. Time. That you are free you eat. Alot. I can't stand to see you two times... chubbier... than you already are. Haven't you heard of a diet? You could get a heart attack! I'm trying to help you... and the rest of Equestria for that matter".
Sunbutt stared at Moonbib, mouth agape, with an offended expression on her face. However, she knew this to be true, so she said nothing. She lay on the floor, not moving. "If you want me to raise the Sun, lift me..."
Moonbib was terrified. She took a deep gulp, and she finally realized the task was too big (literally) for her. "Fine, have it your way, but you're only going to become larger".
At this point, Sunbutt disregarded that fact. She was too overcome with joy to even bother. But as Moonbib trotted out the door, she noticed Moonbib's beautiful body shape once more, and felt nothing but jealous rage. Making sure that Moonbib was out the door, she used her magic horn (though she struggled, as it had sunk into her fat) and unlocked a dressing table drawer.
From outside, Moonbib was peering in through the keyhole, watching, to find out what her sister would do. She expected a full course meal to be pulled from the drawer. Instead, it was a book... a diary. Moonbib leaned closer, her eye almost pressing against the keyhole. She stared with curiosity.
"Dear diary", Sunbutt read out loud like every single diary-reading cartoon character, "It's me! Celestia! I've always wanted a name as royal as that. Instead, I got stuck with Sunbutt. Curse my mother for doing such.. I was supposed to raise the sun today, but-".
Sunbutt stopped as she heard a gasp, and noticed an eye in the keyhole. (How she managed to peer out of the fat covering her eyes, we aren't sure). She tumbled herself off the bed and struggled to her feet. As Moonbib quivered in fear, Sunbutt slid her right hoof across the floor, as if preparing to... CHARGE!
Sunbutt slammed her head against the door, her horn going right through the keyhole. It would have stabbed Moonbib right in the eye if it weren't for the fat surrounding the horn; preventing the horn from going any further into the keyhole.
Moonbib backed away slowly from the door.
There was silence for a while.
Until the Sunbutt began slamming her head vigorously onto the door, and the wood began to break.
Moonbib ran like lightning all the way out the entrance of the castle. She noticed a castle maid and screamed.
"IF SUNBUTT ASKS, I WAS JUST RAISING THE SUN!".

Chapter 2- Lazy Preparations
Sunbutt stopped banging her head against the wooden door, realizing that Moonbib was already long gone. She turned the doorknob cautiously with her magic, and peered out into the empty hallways. Meh, forget it... I'm hungry... Sunbutt trotted off in the direction of the Royal Dining Hall, her stomach sliding after her majestically.
Sunbutt was greeted by numerous bows and cries of "Hail the Princess!" (and also murmurs and hushed whispers, mostly ponies wondering about the great white sack attached to Her Majesty's bottom half of her body) as she entered the huge room. She pounced upon a platter of stuffed apples, eating like she has not eaten for ten years. Never know when a famine is approaching, she thought, trying to brush off guilt.
Keen eyes swept through the piles of edibles as Sunbutt searched greedily for the biggest and juiciest pieces. She looked around the hall, trying to spot Moonbib, but Moonbib was nowhere to be found...
After consuming enough food to have ended world hunger, Sunbutt went to the throne room to sleep, look majestic, and basically spend the rest of the day doing absolutely nothing.I need a new throne, Sunbutt thought moodily. The solid-gold throne seemed to have gotten smaller over the few thousand years of ruling. In her former days, the throne fittted her royal flanks perfectly! Now she had difficulties getting her enlarged thighs into the golden seat.
Sunbutt gave a lazy yawn, unwashed breath polluting the air in front of her face. She forgot to brush her teeth... Just as she was about to drift of into the world of dreams, the air in front of her shimmered an emerald green, followed by trails of smoke. Seconds later, a scroll unfolded itself in front of her face.
Grabbing the scroll in front of her with her telekinesis, she sighed. It was that egghead unicorn, Twilight Twinkle was it?, her student, the princess of friendship. Sunbutt's eyes scanned the text on the paper:
Dear Princess Sunbutt,
Today I learned that, as friends, we must-
Yadda, yadda, yadda,Sunbutt frowned. The Princess of Friendship was sent abroad to study the 'Magic' of Friendship. While that had been useful a few years ago, Sunbutt couldn't care less about friendship nowadays; she has a much more important priority. Friendship certainly does not have magic whatsoever. Sunbutt threw the junk mail into the trash can, where it should belong.
Sometimes it felt as though she were caught in a vicious circle. The more she ate, the fatter she becomes, and the sadder she feels, so the more she binge eats. But Sunbutt simply could not be bothered with such petty things, and being fat was the least of her concerns. Sure she wanted to look as fabulous as Moonbib, but enjoying her life was much, much more important
She sank blissfully into the blubber around her waist, and fell fast asleep.
Meanwhile, Princess Moonbib crept silently from under the toilet seat cover. She sneaked out of the stalls, and exited the toilet (after washing her hooves of course). Glancing into the throne room on her way to the Gala preparations, she made sure that her sister was asleep as to ensure her safety.
Moonbib's brain-dead sister was completely useless at preparations whatsoever. She couldn't prepare the simplest of preparations to save her life! Moonbib walked noiselessly until she felt sure that Sunbutt was unable to hear her.
Out in the Canterlot Gardens, preparations for the uselessly fancy party took place. Ponies were pulling out tables, placing out food, and setting up stalls. Peasants gawked at the Princess and admired her sparkly mane. Moonbib decided that everything was going perfectly (for now) and went to a dark corner of the Garden in order to scheme.
She had just only found out her sister's deepest, darkest secret. Sunbutt. Kept. A. Diary. Moonbib longed to see what sort of things her sister would write in her diary. Moonbib giggled like a naughty filly as she plotted out her plans for later that night.
Sunbutt woke up from her 'nap'. She blinked groggily and slid off the gold chair in a puddle-like fashion. She mustered up just enough energy to lift the mountainous lump of her body of the ground. Rolling out of the door, she trotted (or as you may like to say, squelched) out to the corridors of the palace.
Suddenly, she remembered what took place that morning. Moonbib found out about her diary! A sense of urgency gripped Sunbutt and she waddled quickly to her resting chambers.
Sunbutt bursts into the room, the door shattered under the force of her Fats (gosh, she forgot about the doorknob again!!), and fell flat upon her face. The Sunbutt gasps heavily, trying to pump oxygen into her plaque-filled arteries. She reaches a meaty hoof towards the drawer where she kept the diary.
Thank goodness, it's still there, Sunbutt thought. Glancing around to make sure she wasn't being spied on, she pulled out the diary from the drawers and decided to hide it under her bed. Sunbutt pushed her large head under the bed and slipped her diary into the darkest corner.
I'm safe.
After all that action, all that running/waddling, Sunbutt felt as tired as a sloth and wriggled under the covers of her bed. She was asleep even before her head hit her pillow.
Unknown to the Sunbutt, her sister had put up surveillance spells around the bedroom many years ago. Moonbib knew that her sister would attempt to hide the diary somewhere else after she found out. Moonbib speculated that Sunbutt would be too lazy to even walk out of the room, so she did not bother to put surveillance spells around the outside of the room. Anyway, it didn't matter now.
Moonbib knew the exact location of the diary in the upper-left corner Sunbutt's bed.
