Copromania: How Pin Worm Got Her Nickname

Late last spring...

Eerie Shrine held an unsure expression on her face as she looked over the assortment of bottles that littered the table in front of her, all containing a mysterious pink fluid. There were seven different types of potions and several of each, with the exception of one. She and the other mares were supposed to choose which ever ones they wanted and drink them before the big show started, but the labels alone were making the bat mare hesitant, every vague description more intimidating than the last.

'Ever Flowing Stream, Soft Serve, Booming Thunder, Spewer, Bowl Breaker, Excremental Ecstasy, Maretezuma's Revenge? What in Luna's name are these supposed to do to me?!'

"Pretty nice spread, huh bat butt?"

Eerie jumped slightly, turning her head to see that Peach Melba had appeared next to her. The unicorn joined her in looking over the array of vessels that held unknown effects, looking upon them proudly.

"Sure, you could say that." Eerie answered. "Peach, what exactly are these going to do to us?" She asked, hoping to dispel some of the uneasiness that fluttered through her stomach.

Peach clicked her tongue. *Tsck*, "And ruin the surprise? Come now Eerie, where's the fun in that?"

Eerie looked back at the table, her eyes showing no less concern. Peach sighed and patted a hoof on her withers.

"Hey, just relax, you're gonna be fine. These are special ordered and custom made from Lilac's shop. Even tested a few of them out myself. You're totes gonna love it." She pulled Eerie into a quick hug to give her a little reassurance. "Trust me, I wouldn't put you girls through anything I didn't think you'd all enjoy."

Eerie smiled at that and returned the hug. Peach could be a bonehead sometimes, but she really was sweet. The thestral pulled away from the hug. "Alright, I trust you." she said, before her tone shifted. "But if I end up hating this or something goes wrong, I'll pour everyone of these things down your throat."

Peach's eyes lit up. "Oh baby, don't go threatening me with a good time! Seriously though, once everypony gets going, nopony is gonna wanna stop."

"Speaking of which, how long do we have this place for?" Eerie asked, scanning her eyes around the temporary location. According to Peach, this particular shoot needed more space than their office building could provide, so a small, empty warehouse had been rented out for the event.

"Just the day." Peach said. "So once the boys have the pool set up and their cameras ready, we need to get started asap."

Eerie chuckled. "If you say so."

"Hehe, I do say so. Now, I'm gonna go fetch Porcelain and Pallid real quick. They need to figure out which of these they want before we get star—"

"Yoohoo, Peach? You in here?"

Peach's ears perked up, picking up a familiar voice that she hadn't heard in ages. She turned around to see two zebra mares tracing their eyes all over the warehouse in search of her. She called out to them. "Hey! You finally made it!"

"There you are!" cried one of them as the pair galloped toward Eerie and herself. "Thank Celestia, we forgot the exact address, and this is the fifth warehouse we've tried!" When they were close enough, the one who had been speaking opened up for a hug, which Peach quickly wrapped her in. The two looked at each other for a mere second before passionately locking lips. Their soft moans carried over to Eerie, who looked on with an expression that said, 'typical, but hot'. They soon parted, and turned to Eerie.

"Eerie, these here are my two long time gal pals, Zakura and Zellie! Zakura, Zellie, this is my good friend and fellow professional shit-show ho, Eerie Shrine!" Peach announced happily. Zakura, who Peach had been making out with moments ago, and Zellie stood noticeably shorter than either the unicorn or the bat pony. Zakura's mane was braided and draped elegantly around her slender neck, while Zellie's was done up in a sort of lazy, wet-look mohawk. Despite being just a little shorter, their frames were much more muscular, but still femininely curvy. They shared a bow towards Eerie before Zakura greeted her.

"Hello, Miss Shrine, it's a pleasure to make you're acquaintance."

"Hey there, it's nice to meet you both." Eerie responded warmly.

"Hey girls, you know Eerie here has quite the fondness for asses." Peach blurted. Eerie groaned loudly. Peach never hesitated to jump right into things. "She has pretty good judgement on quality ones, too. You two should let her sample the goods. You know, to see if you're up to par."

The striped equines looked back at Eerie, smirking. "Well now..." Zellie began, speaking for the first time since she arrived. "I can't say I've ever had my backside appraised by a professional before." She took a few steps closer to the thestral, turned and flipped her two-toned tail to the side, revealing a beautiful set of dark grey mare bits. "Please, tell me what you think." Zellie said bewitchingly. "Am I attractive enough for such a publication?"

It was more of a question of how far she was willing to go for such a publication, Eerie thought. Still, the bat pony stared at the anus and marehood presented before her, making her blush intensify. Her career choice notwithstanding, she always felt shy about these kinds of things in front of new ponies. "Mmf. Gorgeous...I-I mean, yeah, definitely attractive enough. Perfect really." Eerie sputtered out.

It was Peaches turn to groan this time. "Ugh, for fucks sake, Eerie, stop acting all coy and get in there!" Peach said impatiently. With a bit of force, Peach put her hoof behind Eerie's head and shoved it under her friends croup and between her ass cheeks. Zellie gasped at the sudden contact, while Eerie moaned into her. Eerie hadn't known this mare two minutes before having her snout pushed into her asshole.

"There ya go~." Peach said, urging her on. "Pretty nice, huh? How 'bout you take a couple whiffs? I know for a fact she smells amazing."

Eerie took a big sniff and slowly exhaled through her mouth, the warm breath tickling the zebra's pussy. Peach was right. Zellie's backdoor scent made her mouth water. She huffed on it some more, filling her lungs to capacity with the smell. It was sour, like a prior bathroom visit mixed with sweat. As she went to take another breath, Eerie's snout was pulled away from Zellie's pungent hole and shoved into Zakura's equally fragrant one that had appeared right next to her. Zakura's was similar but stronger, almost making Eerie tear up. Her sniffing sounded like a dogs, eagerly trying to suck in as much of the smell as possible.

Peach grinned as she watched Eerie getting musk drunk, but knew it needed to come to an end. It was almost show time after all.

"All right, I think you've sampled enough to make a good judgment." said Peach as she pried her friend's face from her other friend's crack. Eerie stumbled back some, shaking the haze from her head. Peach went on. "In case it wasn't obvious, these beauties are gonna be joining are little photoshoot. Speaking of which, Vantage Point and Hotshoe should be done setting up. You fillies pick your poisons while I hunt down the other two."

Just as Peach started to trot, she came to a halt. "Oh! Some quick advice. Each potion lasts a while, so whatever you take should last the shoot. I also wouldn't recommend mixing. You'll probably be fine, but I'm not sure what will happen. Finally, the Excremental Ecstasy one. Everypony should take some of it, but you only need a drop. Any more than that is gonna be way too much of a good thing. That's why there's only one bottle."

Once Peach's disclaimer was finished, she set off to find Porcelain and Pallid. Eerie, Zakura and Zellie looked at each other, then back to the table.

"I suppose we shouldn't dawdle." said Zakura. The pair of zebra's considered their options. Zellie made the first selection, picking up one that was labeled, 'Ever Flowing Stream', followed by Zakura opting for the same plus 'Bowl Breaker'. Eerie and Zellie looked at her befuddled, but she stated simply, "Peach said we would probably be fine. I've known that mare for years, and I'm positive she wouldn't put anything in front of us that could actually hurt us." With that, she popped the corks and drank the two potions, with Zellie following behind with her one.

"Heh, pretty daring, huh?" Eerie said. Feeling a little embolden, Eerie opted for the one labled, 'Maretezuma's Revenge'. She popped the cork and chugged it. The taste reminded her of pink lemonade. With one down, she made a grab for the lone bottle of 'Excremental Ecstasy'.

"Kind of a clunky name." Eerie said, studying the bottle. "I'm just gonna call it Double E." Again, she popped the cork, but instead of chugging it, she delicately took the vessel in her wing claws and tilted it back just far enough to let a single drop, or at least what felt like it, fall into her open mouth. This one had a burn to it, like a shot of liquor. She swallowed, placed the container on the table, then looked back to her new acquaintances.

"Hooo. Alright, I hope you two know what you're in for, 'cause I have a feeling this is gonna get really intense, really fast."

Zakura and Zellie snickered. "Oh, you need not fret for us." Zellie assured Eerie. "Like Zakura said, we've known Peachy for years. We wouldn't expect anything less from her." Zakura took the bottle of Double E in hoof, and administered her own dose. She hoofed it over to Zellie who did the same.

Feeling pumped for the main event, the trio set their sights to the freshly erected swimming pool, and set off, not realizing just how squalid things were about to become.

To say that the six mares in the empty swimming pool were horny would have been a massive understatement.

As it turned out, Excremental Ecstasy was fast acting and had a double effect. The first in being an extremely powerful aphrodisiac.

Vantage Point and Hotshoe, the two camera ponies had not even given the go ahead for the mares to start before Porcelain Wave and Peach Melba were entangled in an almost vicious make-out session. Their lips sucked, slurped and smacked one another's as their tongues battled for dominance. Nopony was quite sure who all had taken what from the potion table. But from all the fondling, kissing, masturbating and needy whimpering, there was no question that everyone had taken a dose of Double E.

Porcelain and Peach had been pushing so hard into each other that they lost their hoofing, and fell to the pool floor belly to belly, with Porcelain on top. The kissing and fondling never let up, save for Peach occasionally breaking to make lascivious comments in between, while her hooves spread Porcelain's ass cheeks wide open for all to see.

"...Hahh...haaahh...yeah, show 'em that cute little asshole of yours, Wavey. How 'bout you give it a few winks?"

Porcelain squirmed in Peach's hooves as she winked her pucker for the cameras and other girls. She clenched it in, and pushed it out, back and forth as Eerie, Pallid, Zakura and Zellie gathered around to admire her holes. On her fifth push out, the pegasus let rip a long, fluttering fart, hitting all four mares surrounding her and Peach with her anal funk.

*FffrrrrRRRRRTTTTTTT*

"Heh, sounds like you drank Booming Thunder." chuckled Peach.

Deep breaths and moans of lust filled the enclosure, the loudest of which came from Eerie, who had been rubbing herself nonstop.

"Hah..hahhnnff, Fuck, I can't take anymore!" Eerie cried as she threw herself into Porcelain's ass, licking rabidly at the exposed, wrinkly muscle. Porcelain moaned into Peach, who never slowed down in exploring her mouth. Soon after Eerie came Zellie, climbing above Porcelain and joining the thestral in lavishing the dark blue sphincter, while Zakura went below to sample her pussy.

With a lashing tongue in every hole on her body, Porcelain's moaning soon turned into squealing as she felt her first orgasm shoot through her. Squirting and shaking, she was quickly losing bodily control, her spoiled pucker now consistently releasing louder and longer farts into the mouths and faces of Eerie and Zellie. The zebra and bat pony slurped at the noisy orifice, occasionally licking against each other. So entranced in the moment, they stared into each other longingly as both of them buried their tongues, sharing the noisy, bubbling hole as it's stink filled their nostrils.

Peach, taking notice that the mare on top of her was getting all of the attention, pulled her lips away from Porcelain.

"Hey you sluts, how's about showing me a little love, huh?!" the unicorn shouted impatiently.

Pallid Crescent, who had been hyper focused on the scene in front of her while she hoofed at her pussy, heard Peach's cry for attention.

"Huff... Don't worry, I got you..." the earth pony panted. Crouching down, Pallid crawled over to the writhing pile of pony flesh and wormed her way underneath Zakura, who was still munching away at Porcelain's folds. Pallid dug her snout into Peach's marehood, who responded with moans of pleasure and relief.

The mare pile twisted and turned as saliva and pussy juice pooled below them, the smell of flatulence and pheromones engulfing the air. Eerie's whole body felt like it was burning up. She was so horny that she thought she might pass out, but she felt more alert than ever. Those thoughts came to an abrupt halt, feeling a stirring in her bowels that quickly built in intensity. Normally, such a sudden pressure would have doubled her over in pain. Her stomach and entire digestive track however, felt different. As the pressure built, Eerie was only feeling more pleasure, like all her insides had become one big erogenous zone. Unbeknownst to her, this was the second effect of the brew she referred to as Double E; making any and all bodily functions feel orgasmic. Her tonguing slowed down, until she stopped entirely, focused solely on the the gratifying burning inside her guts.

"HahhAhhhh....Fuck...Shit! I-I think I'm gonna—"

Eerie's tail whipped to the side, exposing her distended pucker.

*PSSSSSSSSHHHHHHHH*

Suddenly and with no further warning, an eruption of liquid pony shit burst from Eerie's asshole with the force of what felt like a fire hose. She fell into Porcelain, nearly knocking her off of Peach, as the sensation and shear force racked her body with a never before felt euphoria. Eerie howled into the air.

"OHhhhHh SweEeet FucKinG LunAAAH!!!"

All the other mares in the pool stopped their ministrations and turned their heads to see Eerie's whole body shaking as an arch of diarrhea shot across the pool. By the time the flow from her rectum weakened to a dribble, Eerie had covered nearly half of the pool floor in her colonic contents.

"Awww fuckin' A, Eerie!" Peach shouted excitedly. "I was hoping somepony would take Maretezuma's Revenge. That looked like it felt awesome!"

"Huff...huff...s-so...g-good..."

Eerie was shivering, and with what could only be described as the most salacious, satisfied grin a pony could wear, her tongue hanging out as she panted and her eyes glazed over. Her inner thighs and hooves were drenched with urine. She had completely failed to notice her pissing herself while she shit. She barely managed to get to her hooves before she felt that same wonderful heaviness rapidly build in her stomach again. Her legs buckled some, but instead of grunting in discomfort, she let out another moan.

"Ah! Ooo...I..I think I'm gonna do it again!" She stammered.

"Oh, Oh! Like, do it on me Eerie!" Porcelain yelled, wiggling her rump. "Like, spray it all over my butt!"

Eerie heard her but was having trouble moving into position. Peach saw this and took charge.

"Sweet Celestia, this is gonna be hot. Zakura, Zellie, Pallid. Help hold her up, make sure she doesn't fall."

All three mares took heed and pulled away from the pile, clambering to get Eerie into position. Zakura helped Eerie up and held on to her right foreleg, while Zellie took to her left one, both of them helping Eerie aim her butt at Porcelain's. Pallid, who was beginning to feel her own potions kicking in, went behind her and stood on her hindlegs, using her front hooves to spread Eerie's cheeks. Peach continued to do the same for Porcelain while directing her.

"Lift your ass a little more, Wavey. Yeah, perfect! Now get ready, I think she's gonna blow!"

Right on cue, Eerie let out another series of breathy moans, before screaming in delight, as the second flood of shit water surged out of her with the force of a ruptured dam. Eerie's brain again was awash in an unbelievable amount of endorphins.

*PSSSSSSSSHHHHHHHH*

"Ohhhhh Celestia!!! Hnnghh!! I-I'm C-CuMmiNg...f-from my A-AsshoLe!"

The thestral's voice fluctuated wildly as she screamed her depravity out for everypony around her.

The impact of the vile waste hitting Porcelain's asshole forced a yelp out of the pegasus, which in turn became moans of delight. She sighed in bliss as the warm, rancid filth battered and painted her backside, turning her butt and hindlegs from a soft, light blue to a muddy shade of brown. As she relished in the muck, Porcelain swayed her hips left and right, getting every square inch of her ass covered in Eerie's diarrhea. Pallid and the others watched with envy as she bathed in Eerie's rectal gyser, all of whom had been fighting off the need to give in to their own bodies mounting urges. Tempted, Pallid took one of her hooves and put in front of the stream, feeling an incredible amount of pressure splashing against her frog.

"Oh mare, It just keeps coming..." Pallid whispered in awe.

Eventually, Eerie's insane bowel movement died down again, the purple mare's hind legs quivering from the strain. Her grey mane was disheveled and her breathing was heavy, but she still wore the same satisfied, open mouthed smile. The other mares looked at their enclosure, stunned. In just two bursts, the gang found themselves standing, or in Peach and Porcelain's case lying, in a good two or three inches worth of Eerie's shit. While not nearly full, the entirety of the pools floor surface was submerged in pony waste. Peach, still under Porcelain, wriggled around in the mess, loving the sensation of it soaking into the fur on her back. She breathed deep for a sigh, but instead coughed on the thick smell that invaded her airways.

*Cough cough cough*, *Gasp*, "Nnnff. Holy Tartarus, Eerie, that smells awful! Goddesses, I love it. How'd you like your 'shower', Wavey?"

"Mmm, it was so warm. Like, I'm totally ready for another!" Porcelain chirped, then grunted, punctuating her statement with booming fart. Her body shuddered as effect of the Double E turned the discahrge of gas from relieving to sensational.

Peach sniffed at Porcelain's release. "Just give her a minute." she assured. "These potions last about half an hour. The effects can come in waves, but she ain't even close to empty."

Eerie found her legs after being set down by Zukura and Zellie, and Pallid felt her own stomach give a sudden churn. Like Eerie, instead of the unpleasant ache she should have felt, a ripple of bliss shook her bowels, pulling a throaty whine from her. Pallid did her best to keep her tail from flagging, but could only manage to slow it down. Quickly, she called out to the girls around her.

"Hohhh I think I'm gonna burst...Which one of you wants it?"

Peach immediately called dibs.

"Me next! Hurry and waddle your sexy flank over here!"

Pallid made her way around to Peach's head and hovered her ass over the pink unicorn's face.

"Ah, yeah...that's it, let me have it!" Peach said eagerly, opening her mouth wide and sticking out her tongue.

"Ohhh shit, Oh shit...ohhhh mother of Celestia!" Pallid cried.

The ghost-white mare's tail shot straight up as her pucker let out a soft puff of air. A long, thick, steaming rope of soft manure emerged from the protruding anus and gradually made it's way down towards Peach's face.

'Oh...oh yes. She picked Soft Serve.' Peach thought to herself.

The unicorn below shivered with joy as the head of the creamy turd entered her mouth. The taste was so acrid, to the point it almost stung, it's piquancy making Peach tear up. As the unbroken mush descended, Porcelain stuck out her own tongue and pressed it to the smooth surface, letting it slide against her tastebuds as it came down. Inch by inch the poop filled Peach's muzzle, packing her cheeks and overflowing her maw. Eventually, all the space in Peach's mouth was filled to capacity, but the earth mare's excrement continued to pour out unendingly. The filth rapidly began to pile up, first covering Peach's lips, then nose, and so on, until she was forced to shut her eyes as the mound of shit soon covered her face entirely.

Pallid was doing all she could to not stumble backwards. She had not said a word, only whimpers and grunts as she defecated. The feeling was unreal. Through her clouded mind, she thought back to all the times she would joke about her dumps being orgasmic. This was the real deal. She was indeed shitting and cumming at the same time, and it felt out of this world.

Zakura, Zellie and Eerie had all taken a seat around the other three in the bat pony's shit soup. The thestral and two zebra's sat close to each other, scooping up hooffuls of fecal juice and massaging each other's pussies while they watched Pallid bury Peach's head.

Porcelain continued to lick at the growing pile as if it were her favorite ice cream sundae. She stopped for a moment and smacked her lips, then started taking bites out of the dung heap, chewing it into mush and swallowing it. Her slime coated ponut continued to leak effluvium, fluctuating between noisome blasts and hissing gusts, both of which created bursting shit bubbles on the wrinkled surface.

Peach's entire head had been incased in the soft, cushiony warmth of Pallid's rancid emission from neck to crown and up to the tip of her horn. Every little movement of her skull felt the slide and slosh of hot filth that enveloped it. Her tongue wormed to and fro in the mass that still filled her mouth, savoring the strong taste. She chewed on the slimy gunk as much as possible, and swallowed as much as she could without choking on it, the hot paste warming her throat as it slid down.

After what felt like an eternity, Pallid finally felt the load inside her start to ebb. She clenched her pucker and sent the tail end of her turd to the top of the mountain with a wet plap. Then the earth pony, not able keep herself upright, felt her hindlegs give out, and collapsed rump first on top of her shit and Peach's submerged cranium. Pallid moaned aloud as the pile squished back up into her crack and morph around her butt, with Peach's mouth finding itself slapped up against the pale mare's pussy. Ancillary gobs of anal batter flew everywhere on impact, dousing the three voyeuristic mare's still masturbating to the sight.

"MMMFF!" was all a startled Peach Melba could utter, which in turn sent brown chunks flying from her nostrils, letting her breathe through them again.

"Hey, I was eating that!" Porcelain complained, who was now wearing some splattering's of manure on her face. She scowled, then immediately returned to happily eating her 'meal' off of Pallid's cheeks and Peach's neck.

"...Ho...haaah fuck, Peach, what have you done to meee!!!" Pallid called out to the mare under her as she ground her shit covered snatch into her snout. Peach smiled widely beneath the mess, not that anypony could tell. She parted her lips and burrowed her tongue through the mire and into Pallid's vaginal folds, spreading the grime further inside and out. Porcelain Wave gulped down her third mouthful before deciding to join the unicorn in the oral assault, nuzzling her snout into the ass in front of her and seeking out Pallid's barren hole. Her tongue darted through the fleshy exit and right into a fresh wall of feces ready to be expelled. The pegasus leaned further in, sealed her lips around the earth pony pucker and sucked, trying to extract the shit straight into her mouth.

Pallid's mind felt like it was dissolving into a bubbling mass of goop. The only thing she could process was the extreme pleasure that was coursing through her whole body. Between the effects of the potions and the double team lip service she was receiving, she had quickly broken out in a sweat that drenched her from head to hoof. Her asshole and pussy were inflamed with heat and lust. Then her next bowel movement flared up.

"Por...P-Porcelain...I-I have...I h-have to go again!" Pallid warned shakily. Porcelain simply took that as a hint to suck Pallid's ass even harder. Peach also double her efforts, waiting for Pallid's clit to pop out, latching on it and giving it a hard suck as well.

Pallid's orgasms rocked her world, firing off one from both holes simultaneously.

"AAAAAHHHHHHHHHH!!!"

Her shriek rang loud and echoed off the walls of the warehouse. Her marecum shot out and ran down into Peach's nostrils. This sent the mare scrambling, crawling out from beneath both Porcelain and Pallid to catch her breath. Pallid, in the middle of cumming, slumped forward and landed face first into the repulsive broth that the six mares stewed in. Porcelain scooted forward with Pallid's fall, her lips never breaking it's seal around the engorged sphincter. The anal ejaculation sent mare shit careening down the pegasus' gullet and into her stomach. As Porcelain took her fill of the second batch of softened horse apples, Pallid's bladder released it's own payload on Porcelain's chin, dribbling down it and falling into the foul pool. The earth mare groaned into the puddle she was face down in, bubbles rising and popping all around her.

Meanwhile, while the unicorn, earth pony and pegasus wallowed in filth and pleasure, Zakura and Zellie's own potions kicked in nearly at the same time. The two zebra's were bent over in the pool of slop, knelt down on their knees and hocks, being hoofed off by Eerie when a geyser of piss sprang forth from Zellie's swollen pussy, followed almost instantly by Zakura's own stream. Like the mares before them, the effects were extraordinary. Pleasure elevating deep within their bladders, resulting in streams of urine exploding from their cunts in a yellow shower of orgasmic rapture. Eerie never stopped her ministrations as the lovely pair of mares showered her in their golden necter, actually speeding up in an attempt to procure more of the fluids. Between the chorus of pleased moans, panting and Porcelains boisterous ass sounded the sloshing and mashing of piss and shit covered vulvas.

At least until Zakura's other potion kicked in.

"Mmmm-Oof! Oh...Nfff!"

The black and white mare could only manage a miscellany of grunts as her bowels suddenly loaded down with a titanic weight.

"Ah...Ah! Princesses above!"

Zakura's face lowered closer to the putrid waste as she raised her ass up, huffing and straining, her tail whipping to the side as her bulging pucker dilated. At a gruelingly slow pace, the head of a gargantuan turd tried to slide out from Zakura's tight, obsidian anus, her stream of urine never stopping. The feculent mass managed to dislodge itself several inches, but despite Zakura's best efforts, was having trouble pushing out the rest of the near rock hard obstruction.

"Ahh...I can't get it out. I-It's stuck!"

The log in her butt stuck out in the air like a flag pole, glistening beneath the warehouse lights. Zellie turned from Eerie's hoof over to her dear friend's rear end while still spewing her own endless piss stream.

"Miss Shrine! Please, help me dislodge this–Ah!" Zellie pleaded.

Eerie moved her face in closer to the succulent fragment protruding from the constipated zebra and gave the log a big sniff. She gave a satisfied shudder at the stench. While Zellie kept Zakura's cheeks parted, the bat mare took the compacted turd into her mouth and bit into it, sinking her fangs in deep.

As her teeth sunk into the brown mass, Eerie's third wave of liquid shit overloaded her bowels with renewed vigor. She cried out in ecstasy, only to have the sound absorbed by the turd lodged in her mouth. Bitting down harder, Eerie's haunches went into a squat as a torrent of diarrhea rained from her backside. Combined with the continuous streams of piss pouring from the pair of zebras, the septic pond slowly began to rise.

Zellie moved from Zakura's side to standing above her, getting a better angle to help keep her spread open for Eerie. With her ass hovering over Zakura, Zellie's constant flow of pee showered atop her head, drenching her mane and sending golden rivers streaming down her face. The backed up mare mewled from the pleasant warmth that doused her, licking her lips as the urine washed over them.

With the boulder of shit in Eerie's mouth like a fetid cock, she gave it a preliminary suck, pulling what moisture she could from it, clamped down hard and started pulling back, trying her best to dislodge it from Zakura's asshole without biting off the chunk between her lips. It took her great effort to not only control her bite force, but to not slip and fall backwards as her hooves splashed around in the ascending ocean, all while her ass continued to flood the pool with diarrhea.

Zakura's eyes rolled back as the bat pony excavated the unyielding mass. Every inch of poop being pulled out of her felt wonderful. The striped mare did all she could to keep her forelegs from buckling further and sending her face first into the shit soup that inched up towards her.

'Luna's teats, how long is this fucking monster?!' Eerie thought to herself. She had already managed to take several small hoofsteps back, but the enormous pony stool just kept coming out. Her own foul flow had come and gone and she was still tugging on it. At long last, and with one final hard yank, the end of the generously sized log emerged, causing Eerie to accidently bite off the piece in her mouth and tumble backwards, sending her crashing into her watery excrement.

Zellie gazed down into the gaping anus, still pissing on the mare between her hindlegs. She licked her lips with hunger as she peered into the blown out orifice. Zakura had been so loosened up from birthing the fat log that Zellie knew she could fit her whole hoof inside easily. She lowered her muzzle to the worn pucker and drew a deep breath, huffing the pluming anal vapors. She lowered her body more, resting her belly on Zakura's back and pushing her rump against the back of the mare's head, placing her infinite piss stream right against her skull. Closing the gap between her face and Zakura's ass, Zellie extended her tongue and ran it all around the diameter of soft, loose flesh.

The weight of Zellie's ass on the back of her head, and the pleasure she gained from the rimming, caused Zakura to jolt forward enough to dip her snout in the tide of raw sewage. She opened her mouth and moaned into the sludge, letting it flow into her open maw. In her heated, depraved lust, she gulped down the filth as it filled her mouth.

Eerie, having recovered from her fall, sat on her haunches in the waste waters coming up over her flanks, soaked from head to hoof in liquid shit. Both her forehooves were planted between her thighs, rubbing vigorously beneath the waters while she mashed up the nugget in her mouth. Her muffled moans increased in pitch as her colon refilled with another batch of waste begging for expulsion. Her sopping wet tail lifted up, breaching the surface of slop, and moaned in pleasure as a fresh load of diarrhea blasted from under her, creating an undercurrent of shit rocketing through the depths and warming her mare bits.

On the other side of the pool, Porcelain had long since taken her fill of eating the poop from Pallid's ass, and was now content to simply press her face into the earth pony's crack, letting the mushy filth smoosh and smear on her. The pegasus' coat had become mostly a muddy brown, with patches of her originally pale blue color peaking through. Against the perpetually defecating anus of Pallid Crescent, Porcelain Wave's tongue caressed and tantalized in an unceasing attempt at getting every last intestinal emission on her taste buds.

Peach Melba had taken a moment after clearing her sinuses of mare squirt and dung to look around the improvised septic tank that was the swimming pool, and admire the scene of debauchery before her. Everypony was wallowing in a knee high sea of shit that gradually rose higher and higher thanks to Eerie Shrine's volcanic asshole and the zebra's endless urination, given body with the more solid chunks that came from Pallid floating around in the putrid stew. Peach looked down at her hooves, only to see them rendered invisible by the murky waters she stood in. The other mares and herself were completely drenched in shit, piss and cum, and the excretions and orgasms kept on mounting. Lights flashed rapidly from the camera's of the two stallions behind them. They themselves were doing there job with cocks fully erect and dripping, and judging from the ropes of semen running down the edge of the cesspool, had already gotten off at least once. The once pink and sea green unicorn felt a wave of pride accompany the lust burning through her. With her sexual vigor soaring, she splashed through the slop and headed towards Eerie.

The noxious morsel in Eerie's mouth had been devoured entirely, the bat mare content to clop and defecate where she sat, until Peach appeared next to her with a splash, catching her by surprise.

"Feeling good, my little sewer spewer?" Peach said with a wide grin.

"U-uh Huh!" the thestral confirmed. There was a pleading look in her eyes as she answered Peach, like she needed her touch more than anything in Equestria.

Peach looked around, her eyes stopping to appreciate her zebra friends. The rimming that Zellie had been administering to Zakura had become a frantic lapping at a fresh, gigantic turd being pushed out while she continued to shower her in piss. Peach only tore her gaze away from them when she saw the first log that Zakura shat floating nearby like a fecal submarine. She suddenly had an idea strike her, and turned to help Eerie back on her hooves.

"Alright, up and at 'em you nasty-ass mare. I've got something I think you're gonna like."

When Zakura's log floated near her, Peach made a grab for it and studied it in her hoof, taking note of the bitten end. It was colossal. The only time she had ever seen another one even close to it's size was after a week long battle with a particularly bad case of constipation. The log itself was solid. Not hard as a rock, though. There was some give to it's form, but it was definitely sturdy. She turned to the overstimulated bat mare with a salacious glare in her eyes.

"Alright baby, open up real wide now." Peach ordered as she guided the bitten end towards Eerie's muzzle.

Eerie did as she was instructed, opened her mouth widely and stuck out her tongue with an elongated, "Ahhhhhhh". Peach slid the turd in slowly inch by inch, evoking a suppressed moan from Eerie as her maw was filled.

"O-oh fuck, Eerie...that's it...take it all in like nice, fat cock". Peach whispered. The unicorn's pussy was dripping with arousal watching her fellow model take in the mass of filth. Eerie's breathing hastened with excitement as she felt the tip of the intruder push it's way into her throat, only for Peach to cease moving it any further.

"Hah, hah...alright, now just hold it there a sec."

Eerie held about half of the compacted mass in her mouth and throat when Peach inserted the other end of the log into her own maw, her lips slowly but steadily inching towards the bat mare. The two mares locked eyes with each other, there faces drawing nearer, until Peach's lips finally collided with Eerie's, bringing them together in a vulgar kiss with their mouths stuffed with Zakura's shit.

"Mmmph...M-mmmph..."

Both mares shuddered at the obscene act they were engaged in. Then, drawing back some, Peach began fellating her half of the log, bobbing her head back and forth, her lips smashing wetly against Eerie's with every lunge forward. The two took a few steps forward and reared up on their hind legs, wrapping their forelegs around each other in a hug, causing the turd to arch some in the middle. Caught in one another's embrace, both Eerie and Peach bobbed their heads back and forth rapidly, lips crashing in the middle, sending flecks of shit flying off in different directions. The two sets of lips quickly became stained with a fresh coat of dissolved poop as their saliva coated and eroded the feculent faux cock, their moans of pleasure muted by it.

"Mmmph...mmmph....Mmmph!"

Eerie's brain had devolved into nothing but a stew of pleasure receptors within her skull. Her ability to form a coherent thought was thwarted by waves of electric euphoria circulating throughout her body. Only a few single, simple words flashed in her minds eye.

Fuck.

Suck.

Shit.

Cum.

The forward thrusts from Eerie's head became erratic as her bowels filled up again. The hapless purple mare whimpered as another high voltage surge of pleasure hit her. The ocean her and the zebras created was already up to her lower back, and was only getting higher. She stopped her bobbing and looked at Peach with glistening eyes, as though she were scared. How much longer would all this last, she thought. How much more could her mind and body take?

Peach caught the look Eerie gave her and smiled. Not in the mischievous way she had been earlier, but in an almost uncharacteristically motherly way. With the mammoth log of excrement still in their mouths, Peach closed the distance between her and Eerie, kissing her again, but holding it. She tightened her embrace with Eerie, the hug they shared carrying a tenderness to it despite all of the depravity. Eerie closed her eyes, enveloped in the comfort of her friend, and cried out one more time as she released another duel orgasm and her biggest torrent of waste yet. Peach rubbed the overwhelmed mares back as she felt her whole body convulse against hers. Eerie leaned into Peach as her worn out tailhole gushed one last time under the mare-made ocean, raising the 'water' level again.

Zellie, inspired from having witnessed Eerie and Peach's improvised use of Zakura's shit, found herself butt to butt with Zakura. The latter's second load had gotten stuck about halfway out, and instead of trying to use force, Zellie had gone around, lined herself up and penetrated her asshole with the exposed half of Zakura'a log. The two zebras slammed their asses in sync, sending huge splashes of piss and shit all around them as they fucked each other.

As the septic tide rose, the mares activities became more and more submerged beneath it, making it increasingly difficult to keep up all the licking, sucking and fucking. Fortunately, the effects of the potions were starting to die down, and the girls found themselves riding out the last of their orgasms and excretions. The zebra mares relentlessly fucked Zakura's shit into paste, and collided their asses against each other a final time, their marehoods squirting out the final remnants of their potion enchanted piss.

On the far edge of the nearly full pool, Pallid Crescent clung onto the inner rim as she pinched off the last of her mushy load onto Porcelain Wave, whose tireless lapping and nuzzling never stopped in coating herself in every dollop of filth that fell out of the earth pony. The pegasus, from her head to her withers had been entirely caked in Pallid's shit. She would have looked like a mud monster from a far off haunted swamp were it not for her big, bright almond colored eyes peering out from beneath the gunk. The thunderous farts that were so prevalent from the blue mare were still present, but heavily obscured by the diarrhea lake she waddled through, a steady flow of air bubbling up to the surface, creating a fecal jacuzzi.

Pallid was exhausted, and after cutting off the last bit of grime from her sphincter, she loosened her grip on the pools edge and sunk back into the foul brimming liquid. She was shocked to see and feel that the waste level was now up to her neck while standing on all fours.

"Hah, hah...holy mother of Celestia. Eerie and those other two filled this whole damn thing!"

"Nnnf, yeah, no kiddin', huh?" Porcelain chimed in, twirling around in the mire.

Zakura and Zellie, after recovering from their session, could be seen dog paddling in the slop, shoving various land masses of shit that were floating all around out of their way.

In the center of the swimming pool stood Peach Melba and Eerie Shrine, lips still locked and hooves wrapped around each other. Even being reared up on their hind legs the waste water still reached up past their barrels.

Peach opened her eyes and looked at Eerie. Her eyes were still closed. She gave her a gentle shake, but didn't get any response. Nothing except a faint snoring.

'Heh, heheh, oh mare, she actually passed out...' Peach thought to herself amused.

Then Eerie started to move, slowly sliding out of Peach's grip, her half of Zakura's turd slipping past her lips. Peach went wide eyed and tightened her grip on Eerie, keeping her head from going under while chomping down on the huge chunk of shit.

'Ngh! Damn, filly's heavier than she looks.'

With a bit of a struggle, Peach waddled through the muck while fighting to keep the unconscious bat pony above the liquid feces until they got near the pools inner ladder. Once there, she awkwardly rested her haunches on one of the steps and propped Eerie up next to her, the thestrals head resting on Peach's shoulder. The other mares made there way over and gathered round the pair. Porcelain was the first to blurt out.

"Sweet teats, Peach, she's like, dead!" The pegasus said in a panic.

"Shmmph nmmph dmmph!" Peach tried to say with a mouth full of shit. She went crosseyed looking at the log sticking out of her maw and furrowed her brow, spitting it out. "Pthew...she's not dead!" Peach repeated. "She just fainted. Probably was extra sensitive to the potions. I've never seen a mare spew like that before." She said, rubbing her hoof on Eerie's shoulder.

"No shit." Pallid spouted. "Have you looked around? She damn near overflowed this thing all by herself!"

"Dude, d'you like, see her face when she first popped off? I thought she'd have dropped right then." Porcelain commented.

Peach looked down at Eerie. "Yeah, looks like the whole thing really took a lot out of her too. You girls think you can help me get her out of this thing?"

All of the mares helped in getting Eerie out of the pool. The two camera ponies came around and laid out some towels for her to lay on, keeping her from having to lie on the concrete and to soak up some of the mess that dripped off of her.

Once Eerie was safely out of the pool, Peach threw herself back into it, sending waves of filth splashing out. She breached the surface again, sighing with satisfaction.

"Ahhhh. Fuck, this is so awesome, I'm gonna miss having a whole pool of mare shit to swim around in."

The other mares watched as Peach would dive under and burst back up, clumps of shit falling from her face and body.

"Mare, Peach, you're like a pin worm or something. If we don't find you up somepony's ass, you're probably crawling around in their shit!" Pallid joked, sitting on the ladder.

This got a laugh from the group of mares.

"Heheheh, yeah! Maybe Arc should make that her model name from now on!" Porcelain laughed.

Peach scoffed as she did a backstroke in the mess.

"Hey, I'm not some parasite, ya know! That's friggin' gross."

"Gross huh? That's not the chamber pot callin' the toilet white!" Pallid shot back.

Peach just rolled her eyes. "You guys are a bunch of asses!"

"What the fuck is everypony shouting for!"

All the mares in the pool turned their heads to see a very groggy and filthy Eerie climbing up and peering over the pools edge.

"Eerie, you're ok!" Exclaimed Porcelain, who rushed over and pulled the thestral in big, messy hug, dragging her back into the slop. "I thought you like, came to death or something!"

"Urk! To be...fair, I thought I was gonna!" Eerie choked out from the pegasus' death grip. "And what's all the screaming about pin worms? Are one of you nasty bitches carrying that shit?" Eerie's temper was starting to rise.

"Ha, no. The only pin worm in here is that one over there with the horn sticking out of her head." Pallid quipped.

Peach glared in her direction, her swimming coming to a halt. "Getting a little sick of the horseshit, Crescent."

The earth pony laughed, now fully amused by the unicorn's irritation. "Really? 'Cause from this side of the pool it doesn't really look like it, Pin Worm."

"Oh that does it you little smart ass!" Peach's horn lit up and encased some of the more solid waste in it's glow, shaping it into a ball. But before she was able to heave it at the cackling mare, she heard a sharp whistle, then a voice call from behind her. It was Vantage Point.

"Uh, ladies? I don't mean to interrupt, but do you think one of you could lend us a hoof?"

The stallions were sitting on the edge of the pool side by side, each of them sporting throbbing erections. Peach's expression shifted from one of anger to gleeful intrigue. But before she could accept the offer, Zakura and Zellie were already making their way over. The black and white mares approached the two stallions, turned and stuck their rumps as high as they could above the rancid water, wiggling them left to right.

"You boys are more than welcome to relieve yourselves in us" Zakura said. "But only if you join us in here."

Being no strangers to the other mares raunchiness, Vantage and Hotshoe leaped in to the pool without a second thought, sending waves splashing over the two zebras. As fast as they were in the pool they were mounted atop and thrusting desperately into the mares, Hotshoe railing into Zellie's marehood, while Vantage Point hilted himself into Zakura's still loose pucker. Peach just stared at the sight with a twitch in her before yelling.

"Seriously!? After inviting you to this thing, you're both just gonna clam jam me like that!? I still haven't gotten off ya know!"

Still being coddled by Porcelain, Eerie's ears perked up at that.

"Wait, how?" she asked. "I came everytime I emptied my ass thanks to those crazy potions. How'd she not cum even once from them?"

"Oh, she didn't take any, dude." Porcelain answered. "She said something like, she wanted all of her wits about when everything kicked off, or something like that. She wanted to like, be able to appreciate it." Porcelain's answer put a uncomfortable look on Eerie's face.

'That's...disturbingly well thought out for someone like Peach', she thought.

Pallid's taunting laughter ceased when she processed what Peach had said. Hearing that had sent a pang of empathy through her. The whole event had been entirely organized by Peach and it had been the most fun the girls have had at a shoot so far. The earth pony loved to give her a hard time, but wasn't mean enough to let her friend go blue beaned.

"Hey, Eerie, Porcelain, you two wanna gimmie a hoof and help me show Peach a little gratitude?" Pallid asked. Porcelain nodded enthusiastically while Eerie gave a tired sigh.

Pallid hopped from the ladder back into the warm slurry and slowly crept up behind Peach. When she was close enough, she grabbed the unicorn and pulled her under, dragging her back towards the same ladder next to Eerie and Porcelain. Pallid and Peach popped back up, the latter taking a huge gulp of air upon surfacing.

*GAAAAASP*, "WHAT...THE FUCK?!" Peach screamed. Pent up, startled and now angrier than before, the Unicorn was reaching the limits of her patience. But instead of an answer, she felt three pairs of hooves grab and lift her, turning her around and planting her butt on one of the ladder steps above the sea of shit. She looked around bewildered before glancing down, catching the salacious stares of three very, very dirty mares, who much like her self, were no longer their original colors, but instead a mish mash of various browns that dripped and plopped down from their coats.

"So." Pallid began. "Seeing is how your little zebra friends are helping the boys, we thought we'd show our thanks for putting this all together."

Without another word, Eerie, Pallid and Porcelain dove in on Peach, each hungry mouth going for a different part of her. Porcelain went straight for her grungy, muddy pussy, her tongue darting inside, lapping up the filth and fluids. Pallid sealed her lips around her winking clit, licking and sucking on the pulsing bulb of flesh. That left Eerie with her favorite pony hole. The bat hesitated briefly, watching droplets of diarrhea and chunks of soft dung fall from Peach's shit covered ass cheeks. She closed her eyes and pushed her face between them, smearing the mess on her already soiled face. She slid out her long, thestral tongue, and drilled it through her rancid pucker, tasting not just Peach, but the mix of everypony who helped fill the pool that day.

Peach leaned back into the ladder she sat on and groaned in pleasure. Her eyes shifted back and forth from the three mares servicing her to the voracious pounding Hotshoe and Vantage were giving Zakura and Zellie. Every breath she took stung her nostrils. The stallions, the other mares and herself stunk horrifically, but to them it was the best and most powerful pheromone a pony could inhale. Peach rested her head back and let the intense tongue lashing consume her, writhing about on the ladder she sat on, until she howled into the air with delight, showering her friends in a wash of fresh, hot marecum. Life was good.
