Casual Sexquestria

Twilight Sparkle, Rainbow Dash, Applejack, Pinkie Pie, Rarity, Fluttershy, Starlight Glimmer, and the Great and Powerful Trixie were all enjoying a lovely Sunday brunch at Ponyville's newest restaurant Totalement non empoisonné. The group of friends happily dined on eggs, toast, and an assortment of vegetables. Also, mimosas. Lots of mimosas. Which somehow escalated to a bottle of whiskey ending up on the table, three quarters of which were now gone.

Naturally, the addition of large amounts of alcohol to a table with two competitive, loud-mouthed braggarts had ignited a heated debate.

"Don't make me laugh!" Rainbow Dash drunkenly barked at Trixie. "Your ass issnot better than mine!"

"Puh-leeeeeeease!" Trixie retorted, sucking down another shot of whiskey. "Trixie's Great and Powerful posterior is soft and shapely, while yours is hard and flat!"

"Issnot flat!" Rainbow growled, slamming her hooves on the table, before taking another drink straight from the bottle. "Juss because mine isn't fat from sitting on it all day, doesn't mean iss flat. Iss got plenty of cuuurve!"

"I wish that just once," Rarity said, pinching the bridge of her nose. "That we could all have a few drinks like mature adults, without at least one of those two making drunken asses of themselves."

"Whose ass did you juss say was the bess?" Trixie slurred.

"Oh, for the love of-!" Rarity exclaimed, downing the rest of the bottle. "Who the hell even ordered this, anyway?!"

"Um, I did," Fluttershy said. "I was hoping to use it to get enough courage to ask the waiter to bend me over the table and fuck my brains out, but there goes that plan." She turned to Dash and Trixie. "You two are paying for it, by the way."

Rainbow turned to Applejack. "AJ, you think my ass iss awesome, right?"

"Oh no," Applejack replied. "I ain't gettin' involved in you two's petty squabble, especially since I know mine is better than both of y'all's."

"What the hay, AJ!" Dash whined. "I thought we were bess bros! You were supposed to take my side!" She sulked for a moment, before gawking at her friend's flanks. "Fuuuuck, AJ! Your ass iss the bess! I juss wanna take a bite of those juicy apples," she groaned.

"Maybe another time, sugarcube," Applejack said, rising from the table, leaving behind her cut of the bill. "I gotta head back to the farm. Catch y'all, later."

Rainbow turned her attention to Pinkie Pie. "Pinks, you like my ass, don't you?"

"Oh, silly," Pinkie giggled, taking a sip of her third mimosa. "I like all of my friends' butts."

"Gah, you're no help," Dash grumbled.

"As much as Trixie would love to keep hearing about Rainbow Dash's Coltish and Pathetic flanks, can we turn the topic of conversation to my Great and Powerful glutes?" Trixie asked. "Twi-Twi Sparkbutt, Glimmy-Glam, isn't Trixie's rear the finest in all of Equestria?"

"Well, you both have very nice flanks," Starlight replied, carefully wording her answer in an attempt not to hurt either of her friends' feelings.

"Actually," Twilight said. "While your butt is aesthetically pleasing, it is not the best in Equestria. That distinction goes to Princess Celestia, with Princess Luna coming in second place. It's a scientific fact."

"Of course you would kiss your idol's ass!" Trixie snapped. Her expression softened, pondering something. "You're right," she said, in a defeated tone. "Princess Celestia scientifically does have the best butt in the world." She sighed. "So, how do we settle this debate?"

"I gots an idea!" Rainbow blurted. "Meet me in town square t'morrow at noon!" She paused, focusing on something, thinking so hard Rarity swore she saw some smoke coming out of her ears. "Scratch that. G-gonna be hungover t'morrow. Saturday at noon! Bring your stage!"

...

The week passed as it normally did and Twilight had forgotten all about Rainbow Dash's and Trixie's silly, drunken debate, that probably wasn't even going to go anywhere. The day was absolutely gorgeous, so Twilight decided to take a stroll through town, perhaps get herself an ice cream cone, and maybe even let a stallion or two shoot a load deep inside her while she sat under her favorite tree in the park.

Those plans were immediately thrown out the window when she noticed a large crowd gathered in town square, with Trixie's stage set up right in the middle. Trixie's shows were always worth checking out, because even her magic tricks didn't go off perfectly, she always had an amazing grand finale of allowing a few volunteers from the audience gangbang her until she couldn't think straight. That was always worth watching, plus she might get lucky and be chosen to participate.

As Twilight drew nearer, she noticed that instead of the usual props that Trixie used in her performances, there was just two cushions lying on the stage, one supporting Trixie, with Rainbow Dash on the other. A crowd of mares and stallions was gathered around the pair of blue mares, carefully inspecting their flanks. All of them were at least looking, while a bolder few others decided to rub, pinch, squeeze, and spank the pair of beautiful butts. Her attention was then drawn to a sign posted in between the two of them, as well as two jars labeled with their names.

Which butt is better: Trixie's Great and Powerful Plot, or Rainbow Dash's Amazing, Athletic Ass? Place a bit in the jar of your choice. All proceeds go to sick foals, or something.

"I think Trixie's is definitely the better of the two," Noteworthy said, tossing a bit into the jar labeled "TRIXIE". "Hers is far rounder."

"I understand why you would think that," Doctor Whooves said, removing his hoof from Rainbow's cheek, and placing a bit in the opposite container. "But Miss Rainbow Dash's is far firmer. I would expect nothing less from one of Equestria's top athletes."

"Yes, but hers is kinda flat," Lyra said, awarding Trixie a bit.

"Agreed," Bon Bon said, also giving the unicorn a coin. "Trixie's is just so delightfully soft that we really need to invite her over, sometime."

"Trixie is free tomorrow afternoon," the magician said, giving the pair a wink.

"It's a date then," Lyra said, returning the wink.

"You traitors!" Rainbow Dash said in disbelief. "After all those times I let you two double team me?"

"We never said yours was bad," Bon Bon said, sheepishly. "Trixie's is just better."

"Are you two seriously still going on about this?" Twilight interrupted.

"Twilight!" Dash greeted, excitedly. "You're just in time. I know you've spent a lot of time with Princess Celestia, so that's gotta make you an expert on nice butts, so go ahead and explain to everypony why my butt is scientifically superior to Trixie's."

"What's this about my butt?" A regal voice said, catching everypony present off guard. Celestia and Luna had managed to sneak up on the crowd and were now admiring the two flanks presented before them.

"Princess Celestia! Princess Luna!" Trixie said, grinning, and levitating her jar over to them. "You two are mares of most exquisite taste, so I'm sure you two would be willing to vote for Trixie. After all, it's for a good cause."

"Now, now," Luna said, gently pushing the jar of bits away. She stepped closer to Trixie and began to feel up the smaller mare's behind. "If my sister and I are to offer our input on this, we should first take the time to properly evaluate the pros and cons of our options. Isn't that right, Tia?"

"You are most certainly right, dear sister," Celestia said, mimicking Luna's actions on the pegasus. "Mmm, these are quite tight. You simply must tell me what exercises you do to achieve this balance of hard and soft."

"Looking to make the most perfect ass in Equestria even awesomer?" Dash smirked.

"There is always room for improvement," Celestia replied, punctuating her statement with a quick slap to Rainbow's right cheek, before continuing to knead the two globes. As she stroked right where the two orbs met, she was greeted with a wet sensation on her hooves. She smirked, knowingly. "It would appear somepony is enjoying the royal attention."

"Oh, that started long before you showed up," Rainbow said. "You only made it more intense."

"Hmm, I suppose after my sister and I conclude our meeting with Twilight you and I could do something about this. Does seven o'clock work?"

"That would be awesome!" Rainbow moaned.

"It would appear that Miss Trixie also enjoys being the center of attention," Luna said, holding up a glistening hoof, while the other continued to caress the magician's flank.

"Trixie was simply born to be a star," the unicorn said, wiggling her rump.

"Yes, with a rump like this, you were simply destined to have all eyes on you," Luna said, giving Trixie's cutie marks a hearty squeeze. "I simply must spend some more time with you using my face as a throne. Does seven work for you, as well?"

"Of course, Your Highness. Trixie would absolutely adore a private audience with you."

"As much as I think we would both love to keep enjoying you two's bottoms, I think fairness dictates that we switch," Celestia said, removing her hooves from Rainbow's rear, eliciting a needy whine from her.

"Yes, it would be horribly unfair to make our decisions without giving the competition a chance," Luna said, likewise separating herself from Trixie, the smaller unicorn whimpering as her flanks were left unmolested.

Celestia stood before Trixie, wasting little time before taking one of her cheeks in her hoof. "Mmm," she hummed, appreciatively. "This shape... I must say, if I didn't know better, I'd say you were trying to compete with me."

"The Great and Powerful Trixie competing with Her Royal Highness, Princess Celestia? Don't be ridiculous! Nopony could possibly match you!"

"There's no harm in trying," Celestia replied, in an almost predatory manner. "Though, your softness is simply divine. I don't think mine are quite this pliable."

Meanwhile, Luna was hard at work, giving Dash's buttocks a thorough examination. "I can tell you worked hard to earn this body," she said, admiring the way the flesh would snap back into place after spreading both cheeks. "There is a divine firmness to these, but just enough subtle give to prevent them from being all muscle."

"Woah woah woah!" Rainbow exclaimed in shock. "What do you mean I'm not all muscle? Do I need to work out more?"

"No no," Luna chuckled. "Just a little bit of fat can help improve a already great body. Yours has just the right amount to prevent it from being hard and coltish. Strong where it needs to be, with just the right softness to retain your feminine form. Tis a very cute tush"

"I-I'm not cute," Dash stammered, blushing.

"Oh, but you are, Luna said, giving Rainbow an affectionate nip on the ear. "You both are."

A few more minutes passed. Celestia and Luna continued to feel up both mare's behinds, peppering the two of them with compliments, and telling them about some of the plans they had for later that night.

"Well, I do think Luna and I have made our decisions," Celestia announced, stepping back from Rainbow's ass, giving the left cheek a quick kiss.

"Yes, I quite agree," Luna said, giving Trixie's butt one last pinch. "No peeking," she said with a giggle, as her and her sister used their wings to cover the two smaller pony's eyes.

"Why?" Rainbow Dash and Trixie asked in unison.

"We can't have you two knowing which is our favorites," Celestia said.

"It would ruin the fun we have planned for you two, later," Luna added.

There was a soft clink as a coin fell into both jars.

"Now, we'll meet you both back here at seven," Celestia said.

"In the mean time, the two of you need to decide on a bar we can go to," Luna continued. "I think we can all agree some nice brandy would be an excellent way to start the evening."

"Yes, princesses," Dash and Trixie said, before turning to their jars and counting their votes.

Celestia and Luna turned around to see Twilight sitting in a puddles of her own cum, furiously rubbing her slit.

"Oh, Twilight!" Celestia gasped. "We had completely forgotten about you. How terribly rude of us, especially since we came to Ponyville specifically to see you."

"Yes, we are so sorry," Luna said. "Speaking of which, do you think you could go at least one more round? My sister and I came here hoping to gangbang you into a coma, but it appears our plans have changed, but I do think we have time for a quickie before our dates with Miss Rainbow Dash and Miss Trixie, tonight."

...

"So how many you got?" Rainbow Dash asked, counting her last bit.

"One hundred and three," Trixie said in a cocky tone. "What about you?"

"A hundred and three," Dash grumbled. "It's a tie."

"Well, Trixie will admit it must have been a hard choice."

"Yeah," Rainbow agreed. "But if this was a contest on who was the better lay, I would sweep the floor with you!"

"Don't be ridiculous. Trixie would undoubtedly dominate you in that department."

"Same time next week?"

"You're on, featherbrain!"

As the two of them exchanged banter, they couldn't help but notice how nice the other one's ass was. When they were certain that their opponent wasn't looking, they each tossed a bit into the other one's jar.
