An Event of Biblical Proportions

The day started out as any other. The sun rose and gave warmth to the waking land as the moon retreated back into the celestial abyss from whence it came. Ponies awoke and began to go about their days, and the small empire of Equestria began to hum with the murmur of daily pony life. Overlooking all of this hustle and bustle was the highest point in all of the land, the balcony of the bedchambers of the Solar Princess, and standing on that balcony looking out was the idol herself. Princess Celestia of Equestria gazed out over the land she ruled, smiling contentedly and looking forward to the day ahead. It was indeed a day like any other, and like any other day, Celestia did not start out by thinking she would be fucking her sister.

Not that they hadn't fucked before of course, but that is to say, Celestia did not believe that she would be partaking in such... "activities..." today. Tomorrow, however...

After raising the sun, Celestia proceeded from her bedchambers to the royal kitchens, where the royal chefs were preparing a royal breakfast. Said chefs were bustling about the different food prep stations, preparing meals for the day. The princess wove her way through the chaos, making a beeline for the confectionary display on the other side of the room. Chef Gustave was waiting for her there.

"Ah, madame Princess, as punctual as ever, hon hon hon!" the griffon laughed in a thick Prench accent. "What is it I can get for you today?"

Celestia smiled at him, gestring to a thick slice of strawberry cake. "I'll take the cake, if you don't mind." Slice of cake in tow, the solar princess walked back to the residential wing of the castle, flank swaying as she hummed a little tune to herself and ate her cake. The guards lining the hall were lucky enough to be able to sneak subtle glances at the pristine princess pussy underneath her tail as it swayed, perhaps an omen of the events to come.

The alicorn approached a navy blue door, and used her magic to unlock it and enter without even bothering to knock. She closed the door behind her, relocking it. She approached the bed at the center of the room, raising an eyebrow at the sight before her as she took another bite of cake.

Princess Luna lay on her bed, the sheets askew off to the side, vigorously rubbing her dripping wet pussy with a hoof. Her mane was a mess, fanned out on the bed and pillows beneath her head. Her wings were spread underneath her, the feathers at the tip curled upwards in pleasure. The small alicorn's breaths came in ragged pants as she pleasured herself, tiny moans slipping out more and more rapidly.

Celestia swallowed the bite of cake she had in her mouth, licking the remaining frosting off of the spoon. "Good morning, sister," she said nonchalantly. "Getting an early start to the day, are we?" Luna did not reply. Frowning, Celestia decided to try and get her sister's attention in a different fashion.

The alicorn sucked on the spoon for a few more seconds before leaning down and coming face-to-ass with her sister. Taking careful aim, and biting her lip, Celestia slid the wide end of the spoon right into her sister's pert anus.

Luna let out a startled yelp as the object was pushed into her rectum, the new stimulation pushing her over the edge. Marecum sprayed out of her cunt in a strong jet, absolutely drenching Celestia's head and mane. The white alicorn tried to pull her head back, but wasn't fast enough. Not that she was complaining anyways.

"Oh my," chuckled the alicorn as she sat down on the bed next to her sister. "Pent up, much?"

Luna only sighed as she seemingly melted into the bed. "All I can think about is that night with Twilight," she said, panting slightly. "And to my surprise, apparently neither can she! I stumbled into her wet dream, and let me tell you dear sister, if you thought she was dirty with Cadence and Shining..." The younger alicorn trailed off with a shake of her head. "I have no words to describe it."

Celestia smiled, picturing the dirty and kinky events that her former student could have partaken in. She pulled her spoon out of her sister's pucker, noticing with delight how the rounded tip was smeared with feces. Not minding at all, she cut through her slice of cake and took a bite, making sure to clean the spoon thoroughly. She licked her lips and hummed at the pleasant taste of strawberry and fresh fecal fudge. "Mmmm, well I guess I'll have to find out for myself," she replied as she leaned down to plant a not-so-sisterly kiss on Luna's lips. "Enjoy your nap, I'll see you later tonight, my love."

The day came and went with relatively few disturbances. It wasn't until her sister was awake again that things got interesting. The doors to the throne room slammed open and Luna stomped into the room.

"Tia!" she screamed. "Why is all the staff talking about an orgy?!"

With little acknowledgement of her sister's abrupt entry, Celestia procured a small invitation card, and levitated it over to Luna. The dark alicorn took the card and read over it briefly. Then she read it again. Then, for a third time, she very carefully processed each one of the words printed on the paper until she could be sure she had read them one-hundred percent correctly.

The Canterlot Royalty cordially invite you to a fetish-fueled and incestuous night of debauchery for this gathering of biblical proportions.

Princess Luna stared at the parchment in her magical grasp. "Tia, you sent these out to who?!" she gasped.

Celestia held back a yawn as she relaxed back on her throne, flipping through an issue of Playpony. "Oh, a few nobles, Twilight's friends, Cadence, I don't think Shining Armor could make it, maybe a hundred or so random citizens, oh and those two sisters from Ponyville who prepare the best mud baths," she said in a bored tone, only lightening up when she mentioned the mud baths. "Just our close friends."

The parchment in front of Luna burst into a deep blue flame, incinerating it. "Just. Our. Close. Friends." she grumbled. "TIA! YOU INVITED A HUNDRED AND SOME-ODD PONIES TO A SCAT ORGY!"

Annoyed, the alabaster alicorn closed the magazine and tossed it behind the throne. "Not just a scat orgy, I'm sure there will be some plain vanilla sex for Blueblood to join," she muttered. "I tried to think of everypony."

Luna could not have facehooved any harder than in that moment. "It's fine, we can just cancel it," she mumbled into her hoof. She looked back at her sister. "When did you say this was?"

"Tonight."

"TONIGHT!?"

"Lulu dear," Celestia said patiently. "If you continue to yell, I'm going to get the ball gag."

The other princess just sat there in shock. How did Celestia think this was a good idea? It was going to be a scandal! They'd be ruined! "Tia," she said in a quiet squeak. "You can't just have an orgy in the royal throne room."

"I did it like three hundred years ago. Everypony loved it!" the older sister argued.

Luna balked. "What? Why wasn't I invited?"

"You were on the moon, dear."

"Oh... right..."

In the end, the invitations had been sent out, and ponies did show up for the big event. The resulting queue of ponies stretched from the gates of the Canterlot Palace all the way back to the train station. (This was a fairly large distance, for anypony not versed in the civil schematics of the Equestrian capitol.)

Celestia looked out over the eager crowd from the balcony in front of the castle, a smile on her face. It had been so long since such an event had taken place, let alone one as kinky. "Dear sister," she called. "You'll be happy to know we've drawn quite a crowd.

Said sister glared from behind the curtains, a bottle of the strongest Stalliongrad Vodka held aloft in her magic. "Oh yea, Tia," she mumbled. "I'm fucking thrilled."

The alabaster mare sighed. "How can you not be excited, sister?" she asked. "There are hundreds of ponies, ready and willing to be our own personal fetish fuel for the evening!"

Luna took a swig from her bottle before replying. "This will tarnish our reputation forever."

"Oh please," huffed Celestia. "Have you read any of the porno magazines this country produces? Our reputations never existed."

Another swig.

"I'll let you have Twilight for the whole evening," Celestia offered.

"Deal. I call dibs on the ballroom."

The Throne Room

"Whoah, you're kidding me!" exclaimed Rainbow Dash amid the gasps of awe from the group of ponies encircling the throne. "Can Twilight do that?"

Celestia chuckled at the amazement, and flexed her new penis. "She probably can," she said. "I know she's powerful enough, she just needs to focus on the finer details." She ran a bare hoof along its length as she spoke.

Rainbow licked her lips. "I call dibs!" The ponies around her groaned in disappointment.

"Now now," tutted Celestia, idly stroking her cock. "You'll all get your turns." Her attention turned back to the excited cyan pegasus before her. "Now what kind of lube shall we use, hm? We have cum, piss, or scat."

Dash looked like she was going to cum right here. "Can I have all three?" she asked breathlessly.

Celestia grinned, "Of course you can." She spread her legs wide, allowing the stiff, white cock to spring up, towering from her groin while her heavy testicles fell to lay against the marble seat. "All in due time though, why don't you find out how it tastes before we season it."

The pegasus did not need to be asked twice, and approached the throne, drooling as she gazed at the rod of flesh. She pressed her muzzle into its base, inhaling deeply and sampling the heavy musk. Her tongue darted out and licked the surface of those smooth white orbs, taking in the taste of Celestia's private jewels. The faint taste of sweat graced her taste buds, and Rainbow could not help but moan in satisfaction.

Celestia lowered a hoof down, digging it into Dash's prismatic mane encouraging her to get to the main task. The pegasus took the hint, and dragged her tongue up the rock hard shaft, swirling it around the flared head before taking it into her mouth. The princess let out a low moan as Rainbow swallowed her cock, pushing down on the head to try and force her way deeper.

While this was happening, a newcomer entered the fray. The crowd of ponies huddled around the throne parted to let her through. Celestia smirked at their sudden appearance, but said nothing. Wordlessly, they approached the waiting rear of Rainbow Dash, whose tail had been raised high to reveal her dripping privates. Gilda licked her beak at the sight, before extending two claws and ruthlessly burying them in the pegasus pussy before her.

Rainbow gagged on the cock in her throat at the sudden intrusion, and tried to pull her head off, but Celestia's hoof stopped her just before she could get past the tip. She swirled her eyes up at the monarch, only to see the alicorn shake her head silently and apply more pressure back down. Obediently, she continued to suck the alabaster dick as the claws kept finger banging her cunt.

Copious amounts of sopping wet mare juice gushed out around Gilda's claw as Dash's vaginal walls spasmed around the digits. The griffon chuckled as she felt the first of the pegasus' orgasms ripple around her, and lowered her head down near the snatch. Having fucked Dash several times before, she knew what would be coming next.

A jet of yellow piss sprayed out of the cyan pussy as Rainbow's orgasm died down. Gilda's mouth opened wide, catching as much of the deluge she could. Dash was a messy mare, the torrent of urine coating her entire head and splattering to the tiled floor around her. A few ponies nearby even found themselves caught in the splash zone, only strengthening the growing lust in the room.

Celestia licked her lips as she watched the griffon get covered in pegasus pee. The ponies around the room were finally beginning to give into their horny delights, and it would only be a matter of time before the full-blown orgy began. She clenched her eyes shut as her balls stirred, and cum raced up her shaft. Her hoof held Rainbow's head down as she pumped her semen down her throat, letting out a tight grunt as she came. Rainbow managed to release a moan as she sampled the fertile alicorn jizz, her throat vibrating around the alicorn horsecock.

Finally, Celestia released the pegasus' head, and Dash popped off of her cock with a loud gasp. It took her a few moments to catch her breath, weak coughs sputtering out between her deep gasps of air. When she finally composed herself, she looked back to see who it was that had pleasured her. The cocky face of her old friend Gilda sneered back at her, punctuated by a claw holding up a middle talon towards her.

"Gilda?" she choked out, turning around and sitting her tired flank down. "What the fuck are you doing here?"

"Oh you know, I was in the area," the griffon grunted in reply as she licked Dash's residue off of her talons. "I could smell your slutty ass from a mile away."

Rainbow Dash was about to come up for a retort, but was interrupted by the shadow of yet another newcomer leaning over her. She looked up to see the captain of the Wonderbolts herself standing right next to her. "S-spitfire?!"

The flaming pegasus smirked. "Hey, rookie," she said. "I was told I could find you here." The captain of the Wonderbolts turned around and presented her plot to Dash without any hesitation. "Just came over from the ballroom, they said you could help me out with this little mess."

Calling the mess that was Spitfire's backside "little" was a massive understatement. The mare's ass was absolutely ruined. Globs of semi-solid shit clung to both her cheeks, and streaks of cum dribbled out of both her dirty shithole and her gaping cunt. The smell of fresh jizz, scat, and stale piss wafted down to the muzzle right below it, and Rainbow began to drool as the ass was lowered down onto her face.

Spitfire cooed as the pegasus began to lap at her plot, licking up the scat and semen hungrily. She looked over at Celestia, who was reclining in her throne, idly stroking her penis. "Yo, princess," she said. "Need a hole to stick that in?" She opened her mouth wide, and languidly rolled out her tongue.

Celestia did not need any other invitation, and was soon standing before the captain, ruthlessly plunging her cock down the waiting throat. Spitfire moaned around the large phallus, sucking as she relished in the feeling of Rainbow tongue-cleaning her shitty butthole. Celestia's heavy balls smacked into her chin as the mighty penis was shoving in and out of her maw.

Gilda leaned back, watching the events unfold and digging a claw into her dripping snatch. She caught the eye of a random noble pony gazing in her direction, and winked at him. "Hey you," she called, a predatory grin coming over her face. "I gotta take a dump, you in?"

The stallion nodded eagerly, his cock throbbing beneath him as Gilda approached. She pushed him onto his back and turned tail, presenting her ass to him and hovering over his groin. Her anus was already smudged from past bathroom trips, and she never wiped.

"Alright buddy," she grunted. "Here it comes."

A dry fart ripped itself out of Gilda's puckered asshole, before the head of a hard turd pushed through. It slid out slowly as the griffon pushed, crackling as it descended from her anus. It broke off halfway, the solid log dropping beside the turgid member. His penis twitched as the warm poop rolled against it, and he moaned as another airy fart burst out. The rest of her poop crumbled out of her open hole, dry turds falling like pebbles around his cock and balls.

"Sorry," she said after another popping fart. "I guess I'm a little dehydrated today." Another solid log slipped out, falling at the base of his cock with a dull thud. The heart from it warmed his balls, and his rock-hard dick twitched as a rope of semen spurted out of it's tip. "Ha!" laughed Gilda as she continued pushing out her dry waste. "Didn't even need to touch you and you're already cumming just from my droppings!" A streak of cum sprayed up and draped across one of her asscheeks, and another went for the bullseye in her dirty anus. One last clump of shitty pebbles tumbled out of her ass, and she let out a final dry fart before turning around to see her mess.

Gilda mentally complimented herself on her aim, as all of her shit had managed to land around the stallion's now-softening member. She reached down with a claw, and grabbed one of the large nuggets that had been coated with a fresh serving of warm jizz and brought it up to her beak. She gave the turd a heavy sniff before opening up and taking a generous bite out of it. The rancid taste of her own scat flooded her senses and she let out a loud moan as she chewed.

"Mmm, I just love the taste of my own turds, especially when they're glazed!" she said, licking the residue off of her beak. She turned back around and presented her smeared asshole to the stallion. "Now clean me up, dweeb!"

The Ballroom

Equestria's newest princess licked her lips as she watched the fetid brown logs slide out of the rears presented to her. The royal guard assigned to guard her and Luna during the night's events were lined up in a row on top of the banquet table, hind legs spread and tails up. In front of the table was a similar row of unicorn mares from the Canterlot Mage School, repeatedly casting Cadence's "expulsion" spell on the guards.

Twilight drained the rest of the urine filling her wine glass, before holding it back up to the dark plot presented to her. "Mind giving me a refill?" she asked.

Princess Luna grumbled as Cadence lit her horn next to her, and she felt her bladder swell. "When my sister said I would be spending the night with you, this is not exactly what I had pictured, Sparkle." Despite her arguing, a steady stream of piss spewed forth from her pussy into the chalice.

The lavender pony giggled as she pulled the glass away and leaned in to suckle at the leaking pussy lips herself, causing Luna to let loose a pleasant coo. "Admit it, Luna. You're loving this." Another grumble was all she received in reply.

Focusing her attention back on the display before her, Twilight clapped her hooves together. "Alright boys, that looks like a pretty good mound!"

"Twilight?" inquired Cadence. "May I ask what, exactly, you are planning to do with a giant pile of pony poop?"

Twilight gave Cadence an incredulous look as if to say isn't it obvious, before replying. "Have sex in it, of course." With that, the lavender mare stood and approached the pile of dung. The other two alicorns in the room glanced at each other. They were up for some pretty kinky shit, but that was a lot of shit.

The lavender pony let out a soft moan as a forehoof sunk into the edge of the pile, the warm feces squishing underneath it. The smell was almost overwhelming, and Twilight could feel her tail rising along with her arousal. She brought her hoof back up, admiring the clumps of poop that stuck to it before bringing it to her muzzle and licking it. The earthy taste exploded into her mouth and she let out a long moan as her tongue swept the filth from her hoof.

Twilight turned to look back at Luna, eyes half-lidded and shit-stained tongue lolling out of her mouth. "Well? Are you going to join me?"

It was not long before the trio of Equestrian princesses were wildly fucking in the scat mound, shit smearing over every part of their bodies. Twilight and Luna hungrily sucked on each other's tongues, trying to dominate the other in their brutal make out session while Cadence had gone mad in a shit-induced lust, rapidly casting her defecation spell on all three of them, their constant shitting adding to the pile. Occasionally she would mix it up and give one of them explosive diarrhea, the torrent of liquid poop messily bubbling out of their gaping assholes. It was a glorious orchestration of fecal chaos. The sight was definitely one to behold, and almost everypony in the room had gathered around the group, actively fucking, masturbating, or simply pissing and shitting on one another.

Cadence clambered behind the pair, pressing her lips to Luna's loose shithole and slurping at the soft, semi-solid logs that slid out into her waiting mouth. Her filthy hoof was pressed between her legs, frantically rubbing at her lower lips as she ate her fellow alicorn's shit. Behind her, the ring of her anus burned as fetid bursts of liquid scat spewed out of her onto the pile below.

A red pegasus slipped up behind her and pushed her snout right into the alicorn's rear, letting her diarrhea squirt onto her muzzle and into her mouth. Her dark blue mane quickly became ruined with the fecal sludge, and she let out a wanton moan. Appreciating the new attention to her gaping shithole, Cadence cast the spell on her, and the pegasus grunted as a log of shit suddenly slipped past her own anus and fell onto her tail.

Suddenly, the doors to the ballroom slammed open, drawing everypony's attention. They all turned to look at the new arrival, Twilight needing to crane her neck to see over the mound of horseapples surrounding her.

"Trixie demands to know why she was not invited to this gathering!" yelled the newcomer as she stomped over towards the trio of princesses. "Trixie hears that the rest of Equestria got invitations, but not her!" The unicorn stormed right up to the three sitting in the massive pile of filth. "Trixie demands to be included in this... fun..." Trixie froze, sniffing at the air. Her eyes scanned over the scene around her, finally noticing the state that everypony was in. "What... what is going on? Why are you c-covered in each other’s... p-poop?" she asked, eyes wide.

Twilight rolled over beneath Luna, smearing even more creamy scat into her purple coat. "Oh, Trixie," she said apologetically. "I'm so sorry! I had no idea that Celestia hadn't contacted you! But at least you're here now!" She reached out with a shit-covered hoof. "Come here! Let's have some fun, you and I!"

"W-what?!" asked Trixie incredulously, taking a step back.

Luna lifted herself up so that Twilight could stand and walk towards Trixie. The once-lavender mare had a sultry smile on her face as she approached, one that nearly stretched from ear to ear. "Oh come now, Trixie. Don't you want to get down and dirty with me?" she goaded as she stepped closer. "Celestia knows you did all those years ago when you beat the shit out of me." Twilight placed extra emphaisis on the scatalogical slur.

"Ah, uh, Trixie... Trixie doesn't remember that," the blue unicorn muttered weakly.

Twilight stepped ever closer as Trixie was backed up against the edge of a table. Soon, the two rivals were muzzle-to-muzzle, and Twilight grinned wickedly. Trixie could smell the horseapples coating the alicorn's fur, and her eyes focused on the brown smears staining her teeth and lips.

"Are you sure you don't want to have some fun?" Twilight asked, making sure the stench of her breath blew directly into Trixie's nose.

Trixie reluctantly sniffed at the air, the smell of shit on Twilight's breath causing her to shudder. "M-maybe," she muttered as her eyes locked onto Twilight's.

The alicorn grinned in victory, and moved the final distance, locking her lips with Trixie's. The unicorn quickly gave into the action, kissing her back eagerly. The bitter taste of horse shit exploded into Trixie's mouth, and she felt as though she should be disgusted by the mere concept. However, in reality, the flavor somehow only heightened her arousal. Trixie found herself digging her tongue further into Twilight's mouth, trying to get at more and more of the creamy waste, eagerly sucking it up from her gums.

Twilight pulled away from the unicorn's probing tongue and giggled as Trixie tried to chase after her. "Whoa there," she said with a smile. "Why don't you try some from the source?" Trixie began to salivate and Twilight burst out laughing. "Wow, you turned the page real quick."

"Yesss," moaned Trixie as Twilight turned around and walked back towards the pile of shit. "Trixie has become a slut for your poop!" She trotted after the alicorn and nuzzled underneath her tail, pushing her muzzle into the messy rear. Twilight giggled at the enthusiasm, and squeezed her rectum. A wet fart bubbled out, and Trixie snorted it up eagerly. "Mmm, yes!" she cried, pressing her nose against Twilight's dirty anus. "Make Trixie your personal ass-sniffer! Drown her with your poop and farts!"

"Oh my gosh. Twilight, you broke her," commented Cadence as the two stepped into the pile of dung, rejoining the other two princesses.

Trixie's face was still buried under Twilight's tail as the alicorn stepped up to Luna, kissing her passionately before replying. "Nopony can resist the alluring scent of my nasty plot," she said with a wink as she farted in Trixie's face again. Her horn lit up and she lifted a clump of wet shit from the ground beside her, bringing it up between her and Luna's mouth as she two kissed again. The shit smeared across their muzzles as their tongues wrestled in each other's mouths, sharing the tasty filth between them.

Cadence approached Trixie, who was now lovingly making out with Twilight's anus. Most of the scat had been cleaned from the pucker, slurped up by the unicorn's cleansing tongue. She slobbered hungrily all over the ponut, moaning and sniffing all the while.

"You look like you're having a good time back here," said Cadence in a low voice as she leaned in beside her. Their cheeks were touching, and Cadence could smell the musky smell of Twilight's anus from here. Trixie mumbled in reply, darting her eyes at the princess without stopping. "Wouldn't it be more fun if Twily was little more... active... back here?" she asked, sultrily trailing her tongue on the unicorn's cheek.

That got Trixies attention. She pulled away from Twilight's ass to whisper, "What do you mean?"

Cadence smiled as her horn lit up. Twilight felt a gurgle in her gut as her intestines were suddenly filled with shit, and she groaned at the sudden pressure. Not caring at all, she began to push, and her butthole let out a bubbly fart before a semi-solid load of horseapples peeked out. Trixie stared into the hole as it opened up, and watched as the soft crap inched towards her. The first part of the log broke off and fell to the pile below with a wet splat, and the rest kept up the pace.

"Go on," encouraged Cadence. "You know you want to."

Trixie did want to. She parted her lips and leaned forward, sealing her mouth around Twilight's asshole and letting her shit slide right into her mouth. The soft log hit her tongue, and the sour, bitter flavor of fresh pony poop exploded into her mouth. It overwhelmed her senses, and she moaned. The shit filled her mouth as Twilight pushed it out, the volume quickly overwhelming her small maw and causing her to back away. The remainder of what was left in the alicorn's colon coiled out, smearing across Trixie's face and plopping down onto the pile between them.

Cadence licked at the smear on her cheek as the unicorn tried to chew through what was in her mouth. "Mmm, it always tastes better when it's fresh," Cadence murmured in the light blue ear as she turned around to peek underneath Trixie's tail. "Let's try some of your own batch."

Before Trixie even knew what was happening, she winced as she felt her colon fill up with shit that had not been there moments prior. "Oh my goodness," she grunted, a tight poot slipping out of her rear. "Trixie has to... Trixie has to poop!" Her anus opened up and a solid turd immediately slid out.

The pink alicorn lifted the tail out of the way, and breathed in the scent of freshly baked horseapples. She leaned in as another log made its way out, nuzzling her cheek into one of Trixie's buttcheeks as she watched. The turd dangled down from the unicorn's ass before slipping out the rest of the way. Cadence caught it in her hoof, and brought it up to her nose to take a deep whiff. She sighed in satisfaction as the stench flooded her nose, and she went back over to Trixie's front end as the unicorn continued to pinch off her logs.

"Here you go," Cadence said, lifting the turd in her hoof up to Trixie's face. "Look what you made."

Trixie sniffed at the crap, before giving it a slobbering lick. "Mmm, that came out of Trixie," she said in awe, and Cadence nodded. Without any hesitation, the unicorn licked her own poop again before sucking it into her mouth. The pink alicorn went to kiss Trixie on the lips, taking the other end of the turd in her own mouth. The two ponies slurped and slobbered on it, mashing it between their locked lips and sharing in its filth. Their muzzles mashed together until there was nothing left of the log, and they were left to passionately make out and taste the scat on each other's tongues.

Eventually they needed to pull apart for air, and Cadence smiled as Trixie smacked her lips. "You look a little thirsty there," she noted, leaning back and spreading her hind legs. "Why don't you stop for a drink?" Her magic flashed for a third time, and suddenly a stream of golden piss was spraying out and splattering into the mush below.

Trixie leaned in and lapped at the acrid fountain, her dirty lips pressing against Cadence's pussy. She greedily slurped at the drink, her mind making it akin to the most refreshing beverage she had ever consumed. It mixed with the poop in her mouth and washed it away with its cleansing flavor, and Trixie guzzled it down, gulp after gulp.

The door to the ballroom slammed open once again, and Princess Celestia stepped through the open doorway. The alicorn stood there with her massive, godlike cock dangling between her hind legs and her hefty ballsack hanging behind it. Its white girth was coated in a collective slime of cum, feces and urine, the myriad of filth smearing across various parts of her body as well. She paused in the doorway, straining her face and lifting one of her hind legs. A booming wet fart sputtered out of her ass followed by a torrent of wet fecal slop. It splattered onto the tiled floor beneath her legs, and Celestia let out a relieved sigh as she punctuated her explosive shit with another fart and lowered her leg.

"Sister!" cheered Luna, pulling away from Twilight. "Come over here and rut me!"

Celestia farted again, a few more flecks of wet shit spraying out of her butthole before she headed over to the pile of shit in the center of the ballroom. "Wow, you've been busy," she commented as her hooves squished into the horseapples. She leaned over to give Luna a deep kiss, relishing the sensation of so many different flavors of scat that coated the inside of her sister's mouth.

Luna pulled away from her sister and turned around, bending her forelegs and raising her ass up. She flipped her tail up and revealed her nasty plot to the larger alicorn. Celestia's dick throbbed in appreciation for the view, and she stepped over her sister. She lined the tip of her cock up with Luna's messy anus and thrusted, sinking into the darker alicorn's backdoor.

Celestia moaned as her penis carved through the shit in her sister's rectum, smearing her shaft with even more pony poop. She fucked her sister harder, gripping her forelegs around the torso beneath her and lowering her upper body across Luna's back. Her heavy balls smacked against Luna's dripping pussy with wet slaps as Celestia's hips slammed in and out. Luna howled with pleasure as she was anally fucked, eyes squeezed shut and tongue lolling out in sheer bliss.

Twilight stepped up behind Celestia, brushing her majestic tail out of the way. She licked her lips as she gazed at the princess' once white plot, now coated with chunks of liquid scat. Her puckered anus clenched as she fucked her sister's shitter, and her thrusting stopped as she hilted herself inside the dark blue ass. Twilight watched as Celestia's balls clenched, unleashing her royal spunk deep into her sister's colon.

With Celestia's butt no longer thrashing about, Twilight took the opportunity to lean in and lap at her former mentor's dirty pucker. Her tongue scraped across the wrinkled flesh, scooping up all of the mucky shit that remained. The watery waste had a spicy tang to it, and Twilight hummed in satisfaction as she cleaned Celestia's rear.

The unexpected rimjob sent pleasant aftershocks through Celestia's orgasm, and she flexed against her sister's ass in pleasurable, small thrusts. Her mouth found one of Luna's ears, and she gently nibbled on it, pulling a soft coo out of the dark blue alicorn beneath her. Eventually though, Celestia pulled out of her sister's anus, her large cock flopping out swinging beneath her stomach as she backed up.

Twilight immediately shifted targets to slurp at the warm cum dribbling out of Luna's gaping anus, the salty flavor of Celestia's seed mixing with the bitterness of Luna's poop. Cadence slipped under Celestia and suckled on her softening cock, cleaning the shit and grime from it's length before it retreated back into its sheath.

Gradually, the filthy fetishistic pleasures around the palace slowed down, with ponies either taking it upon themselves to find a lover and leave for a more private location, or simply finding the nearest cushion to pass out on. The halls and rooms of Canterlot Castle were wrecked, piss, shit and cum splattered on every possible surface. Later on, the residents of Canterlot would claim to be able to smell the wafting scent of stale scat drifting from the palace's open windows for days to come. But the truth was, none of them really minded.

The Great Canterlot Orgy would be remembered for quite some time afterwards, many ponies looking back on the event with fond memories, and some having even met their future spouses there. There were calls for the royalty to turn the orgy into an annual event, and while the idea was given some thought and plans were made, they never came to pass. But the original was an event of biblical proportions, and it would go down in Equestrian history as one of the greatest social events that pony society had ever hosted.

"Isn't the downvote joke getting old?" No, no it isn't.

I think I had too much fun while writing this.
