The Smallest Butt
In the Royal Dining Room of Canterlot Castle, Princess Luna sat around a circular white marble table. She glared angrily at a particularly large pink rump across from the room from her. Bigger than everypony else’s combined.
“Oh my, Flurry Heart. The stallions must not be able to keep their eyes off you,” said Celestia, giving her cutie mark a tender kiss with a wet smooching sound.
“Hehe, yeah. The stallions go crazy for my butt. And I’m only getting bigger and bigger,” she giggled with pride, shaking her ass from side to side, this created a loud meaty slapping sound as her massive buttcheeks smacked against one another as her ass jiggled wildly about during her movements.
“That’s my girl!” said Cadance, looking at her grown daughter's massive rump with tears of joy in her eyes.
“Thanks, Mom!”
Twilight spoke up. “If you keep following that diet book I gave you it will help your butt grow bigger. I want to see that butt get bigger.”
“Thanks, Twilight. That book really helps. I really feel I am gaining even more inches in height from it.”
“Oh, you’re welcome,” said Twilight, blushing profusely.
Luna did her best to hide her jealousy, for she had by far the smallest butt of everypony in this room. ‘Butt’ it was becoming difficult since the other princesses kept talking about Flurry Heart’s butt. It was almost as if they had an obsession with butts. Twilight Sparkle, Princess Cadence, and especially Flurry Heart had grown much larger. And as if the universe itself hated her, Princess Celestia somehow got even larger again. Twilight was about six feet tall. Matching Princess Celestia before she got even bigger. Cadance was of a similar case. She, however, was about 7 feet tall now.
She thought Princess Celestia has fully grown already. Not only that, ever since they both retired Princess Celestia’s pig eating habits got even worse. She ate more fattening food than ever before. Rather than punish her for her gluttony, she became taller to compensate for the extra fat she gained from inhaling cake into her. She also became a total whorse. She shook her massive metaphorical monster truck of an ass everywhere she went and slept with random ponies seemingly every day.
Luna tried inhaling food into herself. But it appeared her metabolism was so high that she wasn't able to gain weight. She watched Celestia steadily gain more inches in height over the years, the mare was about 9 feet tall or so now. And she watched her calves literally explode in size as her ass seemingly air ballooned in growth. Luna on the other hoof was just one foot taller than your average 4 and a half feet tall pony.
Every time, she and her sister went to a nightclub, all the stallions would pay attention to her and completely ignore her. It seemed she was nothing more than her wing mare. As of right now all the princesses in the room apart from herself, were fondling Princess Flurry Heart’s absolutely enormous rump. What’s worse, Flurry Heart was not done growing. She was only in her early 20s. Alicorns tend to get bigger by at least another 20 more years or so. She was about the same age when Twilight became one, so that ass was only going to get even bigger.
Flurry Heart was a lumbering titan of a mare. She was about the size of an elephant, if not even bigger. The mare stood at least 14 feet tall or so. Again she's not done growing. Flurry Heart giggled with a hoof over her mouth as all the princesses in the room admired her ass. Their hooves dug into the squishy softness of her thick rump.
Luna looked back at her own backside. It was bony thin in comparison to the other princesses in the room. A single tear fell down her cheek. An anger grew inside her. An anger she had not felt for a long time.
Her heart began to race when she heard a familiar voice speaking to her. It whispered in a sinister tone. “Lllluuuunnnnaaaa, it appears Celestia has betrayed you. Just like I told you she would.”
“No,” she whispered back. “She would never. I won’t let you take control, Nightmare Moon.”
“Come now, Luna. If you allow me to take control. I will give you the backside that you desire. You will even surpass Flurry Heart in magnificence.”
“I-I--” Luna was cut off when she saw Celestia’s face in front of her. Celestia looked down at Luna with concern.
“Dear sister, are you okay?” Celestia said softly.
Luna opened her mouth to speak, creating an ‘O’ shape, before closing it. She could not find the words to reply. She felt embarrassed as everypony in the room was staring at her, their eyes ripe with concern.
Flurry Heart stepped forward and kneeled down to face Luna. “Luna, can I speak plainly?”
“Uhhh, yes.”
“Any stallion who does not want to rut you will never get to rut my ass. All the stallions who get to rut me want to rut you too. I can sense their appreciation for asses, big and small. Any stallion who thinks less of you will never get to tap my ass.”
Tears of joy fell down Luna’s cheeks. “Really, is this true?”
“Yes. When we hit the nightclub tonight. I’ll help you get some nice handsome stallions to rut you. Any stallion who is cruel to you will get blue balls tonight. They will watch my big fat ass bounce up and down a nice stallion who treats you with respect.”
“Uhhh, not to spoil the mood. But wouldn’t your ass break their pelvis? Or their body for that matter?” Luna said in a worried tone.
Flurry Heart giggled with a hoof over her mouth. “I’ll just use weight protection magic, silly.”
Just then five additional alicorns walked into the room. Each one was bigger than Luna. Said alicorns were; Rainbow Dash, Fluttershy, Pinkie Pie, Rarity, and Applejack. Luna smiled at the sight of them. She didn't care that these new alicorns were actually bigger than her. However, none of them were nearly as big as Flurry Heart.
The darkness of Nightmare Moon crept back into the back of her mind. She may be small, but thanks to Flurry Heart’s words she felt sexy again.
“Let’s get this party started!” boomed Pinkie Pie, standing about 7 feet tall, while shaking her massive beachball-like asscheeks from side-to-side, creating loud meaty slapping sounds of flesh slapping against flesh.
