So That's What The Smell Was

The Ponyville Day spa was perhaps the most popular spa in rural Equestria. It was frequented by Canterlot Royalty, including the Princesses themselves, and almost always had bookings for days in advance. No other spa could quite mimic the unique methods that the spa's owners utilized, nor the rejuvenating properties of their most popular treatment: Their mud baths.

Their mud baths were so popular, in fact, that the two spa ponies needed to limit them to just one per day, as to not run out of whatever supplies were necessary to make them. And today's booking had been scheduled for two of Ponyville's very own.

Rarity and Fluttershy trotted up the pathway to the spa, idly chatting about whatever it was that had sparked their interest. They were fairly early for their appointment, so they took their time in meandering up to the building, before entering.

"I've never had one of their mud baths before, Rarity," said Fluttershy, a slight hint of excitement in her voice.

Rarity smiled at the minor show of enthusiasm from her yellow friend. "Oh, darling, they are simply divine!" She raised a hoof to her chest in emphasis. "The smell is a little peculiar, but the results are exquisite!"

A note had been left on the front desk, Aloe's neat penmanship reading "Will return soon, preparing for a customer."

"I had always wondered how she managed to write so pristinely without a horn," muttered Rarity as she placed the note back on the counter. "No matter, we'll just see ourselves in!"

"O-oh," said Fluttershy. "Are you sure that it's okay for us to do that?"

The white unicorn waved a hoof in reply. "Of course, my dear! Aloe and Lotus a dear friends of mine. I'd love to have a quick chat before our treatment anyways!"

"B-but if they're making the mud bath, it's a... a secret!"

Again Rarity dismissed the protest. "Well then we just won't tell anypony. I'm sure they can trust us!"

Not wanting to argue, Fluttershy followed her friend through the doorway and towards the back of the spa where the mud bath was. Sounds of splashing and giggling filtered through the curtain parting the room from the hallway as the two ponies approached. Suddenly, Rarity abruptly stopped and Fluttershy found herself accidentally bumping into the white flank in front of her.

"Oh! Sorry Rarity! Why d-" Fluttershy was in the middle of apologizing when a hoof was suddenly pressed up against her muzzle, silencing her. The pegasus looked to her friend, wondering why she would have done that when she was dragged forward by Rarity's other hoof, and allowed to peer through the small gap in the curtain. What she saw was, to say the least, surprising.

The two sisters were indeed in the room, preparing the mud bath for Rarity and Fluttershy. A hose had been brought up to the edge of the wooden tub, and was steadily pumping water in as expected. However what was not expected was Lotus hovering her plot over the edge of the tub, and letting loose a stream of urine into the water. Even less expected was Aloe sitting the the tub beneath her sister's butt, cupping her hooves in the piss stream and playfully splashing it about.

Aloe leaned up and lapped at her sister's leaking pussy, drinking the urine straight from the source. Lotus let out a loud moan, her voice echoing in the mostly empty room. "Oh yesssss sister," she cried out. "Keep licking right there!" Aloe obliged, her tongue diving into the wet snatch even as the stream of piss came to an end.

Fluttershy could not believe was she was seeing. It was so kinky! And so taboo! A blush had almost instantly formed on her pale yellow features, yet she could not look away. Something about the scene before her was so fascinating, and she felt a warm sensation rising up from her core. What gave away her growing lust the most was the pool of liquid slowly beginning to pool beneath her hind legs.

Beside her, Rarity was in a similar state, however was much more active about relieving herself. The white unicorn had surreptitiously lit her horn, and was magically toying with her dripping pussy. The light blue glow repeatedly tweaked her winking clit, before circling around her puffed out lips, spreading them and then heading back down to the bud below. She did her best to steady her breathing, but it was only a matter of time before she was quietly panting in pleasure.

Back in the room, Lotus had stood and pried her vagina away from her sister's tongue. Aloe had likewise climbed out of the water and followed her sister over to a trio of smaller barrels containing the mixtures of powder that would go into the actual mud bath. Lotus nudged one of them over the the tub, and leaned into it, tipping it over and allowing the contents to spill into the water. Her sister followed with the second one while she took care of the third.

Aloe began to mix the bath with a large wooden paddle, spreading the contents out thoroughly. "Are you ready for the last ingredient?" she asked as she looked back over her shoulder at her sister, who was dragging a large pallet of burlap sacks over to the edge of the bath.

"Mhm," came Lotus' sultry reply. "But perhaps we need to top the load off, this bag feels kind of lighter than the rest." She hefted up one of the sacks, standing it upright and allowing the two ponies in the doorway to read the label clearly.

Pear Family Farms' Manure Delivery

Rarity paused her masturbating to side a quick glance at Fluttershy. That couldn't be... they wouldn't use... However her thoughts were derailed as she saw that her timid friend had begun drooling at the sight. One of her yellow wings had snaked down between her hind legs and she was gently teasing herself.

The white unicorn smiled. 'Oh Fluttershy, I had no idea you were so kinky!' she thought to herself before returning her attention to the two spa ponies.

Aloe had finished mixing the bath together, and had joined Lotus as the blue pony ripped open the sack. The smell of stale horseapples wafted up to them, and they both took a deep whiff before sighing.

Lotus hovered her flank over the open top of the bag, raising her tail up and out of the way. Her sister leaned in for the front row seat, casually slipping a hoof between her legs as she waited for the show to begin. She did not have to wait long. A grunt came from the blue pony, before a weak fart sputtered out of her. Lotus let out a soft moan as her anus opened up around the head of a log, a few dribbles of residual urine leaking out of her pussy as she pushed.

The turd slid forward, inching its way down towards the bag below. Before it could land however, Aloe reached out with her free hoof and caught it, the weight settling in her grasp as Lotus pinched it off at the end. She brought the fresh load up her muzzle and breathed in deeply, the fetid stench settling in her nostrils and causing her to moan. Unable to help herself, she opened up her mouth and leaned in to give the log a lick.

"Aloe!" Lotus chastised as she saw what her sister was doing. "We need that for the bath!" But she could not help but giggle as she watched her sister run her tongue along the length lustfully. The pink hoof in between her legs worked harder as the bitter taste hit her senses.

Fluttershy and Rarity's eyes widened at the display, before Rarity's eyes rolled upward as she stuffed the entirety of her magic aura into her sopping wet cunt. Beside her, Fluttershy raised her feathers upward and began toying them around the edge of her puffy anus, easily slipping one inside. Now furiously masturbating together, they returned their attention to show that the two spa ponies were putting on before them.

Aloe had finished licking the log, and chose to bring it down to right above her crotch where her two tits poked up through her fur, pert from her arousal. Without any hesitation, she pushed the shit in between the mounds mushing and smearing the scat into her fur.

Deciding that they had plenty of manure to use for the bath, and quite frankly enjoying her sister's actions, Lotus decided to throw caution to the wind and stepped to the side of the sack. Her behind was now positioned over her sister's sitting form, with her butthole hovering right over her face. With a sultry grin and a crude fart, she began to push again.

The passing of gas above her caused Aloe to open her eyes, only to be met with her sister's blue plot. Lotus' anus opened back up to reveal the head of another turd sliding out. This one was much softer in consistency, smearing its filth over Aloe's face as it draped over her muzzle, before falling to the floor with a dull, wet splat.

Aloe's body began to shudder as her hoof ground into her sopping pussy faster, quickly approaching her orgasm. Her mouth was wide open, and she was panting as she approached her peak. Lotus let another wet fart rip from her stained butthole, before a final small coil of soft, creamy shit slithered out right into her sister's open mouth. It was this final act that pushed Aloe over the edge, and the pink pony let out a loud moan as she finally reached her climax.

An arc of marecum squirted out of Aloe's quivering cunt, spraying into the mud in front of her. Her hind legs trembled as she moaned in ecstasy, her sister's creamy poop squishing around her mouth. The bitter, disgusting flavor coated her tongue, and as pleasurable as the taste was, the pink mare had to fight her urge to gag.

Lotus wiggled her rear over her sister's face, giggling as she watched Aloe enjoy her scat. She spun around and leaned down in front of her, playfully licking at one of Aloe's shit-covered nipples. Aloe twitched at the contact and smiled down blissfully, showing off her stained teeth. Unable to help herself, Lotus leaned up and kissed her sister, hungrily stuffing her tongue in the other mare's mouth, desperate for a taste of her own waste.

Aloe eagerly accepted the intruder, sharing whatever was left of the creamy shit. The two sisters continued to make out for a few moments before Aloe pushed her sister away slightly and whispered in her ear. "I gotta go too, you know."

"Quickly," Lotus replied. "Rarity and her friend will be here soon!"

The two voyeurs outside briefly paused at the mention of their name, but wasted no time in resuming their masturbating. Rarity had fallen into a crouched stance as a magical phallus of her own conjuring rapidly pistoned in and out of her gaping pussy. Fluttershy had taken to lying on her back while stuffing as many feathers as she could up her tight butthole, while rapidly rubbing her wet cunt with a free hoof.

Back in the room, Aloe had scooted her butt forward so that it was dangling over the edge of the tub. Lotus held her sisters rear legs apart, spreading them as wide as they would go. Between Aloe's pert ass cheeks, her tight rosebud flexed a few times before whispering out an airy fart. There was a moment of silence, before the anus opened back up around the head of a solid turd.

The brown log slid forward out of Aloe's ass rapidly. Inch by inch it slid out until it's head was kissing the surface of the mud bath. And still it kept sliding out softly crackling as it did so. After what seemed like feet of shit had slid out, the rest rapidly slid out, leaving a gaping hole in its place. A booming trumpet of a fart followed the turd's exit, echoing through the room.

Lotus sniffed, breathing in the foul stench of her sister's anal air. She leaned down in between Aloe's sullied breasts and locked her lips around the gaping anus, sucking on it gently. Her tongue traced around the wrinkled rim, scraping up the slimey remains of her bowel movement, and gratefully relishing the taste before pulling away. Her tongue trailed up over the wet pussy before settling on a shit-coated nipple and sucking lightly.

Rarity's eyes locked onto Aloe's soiled butthole as it slowly tightened back up. She bit down on her lip hard as the sight pushed her over the edge, and she came. The unicorn shuddered as she plugned the magical phallus into the depths of her sopping wet cunt, spraying her juices all over the tiled floor. Her eyes rolled back in her head, and she did her best to keep from moaning until she stopped squirting.

Hearing her friend climax right next to her pushed Fluttershy along as well, and the yellow pegasus violently convulsed as she experienced one of the most powerful orgasms of her life. Her pussy gushed marecum as she pulled her feathers out of her ass. Her anus clenched around the sudden emptiness, and her bowels squeezed. Unable to control it, a small soft horseapple squeezed its way out right behind her feathers, landing with a wet plop on top of her tail. She shivered as she lost control of her bladder as well, a weak arc of piss splattering out of her wet slit.

The two ponies lay there, panting as they both came down from their orgasmic highs. Rarity glanced over at Fluttershy, eyes widening as she saw the damage. The pegasus was sprawled out on her back, her wings spread out under her. The once yellow tips of her wings were stained a deep brown, saturated with fecal sludge. Her pink tail was coated in her arousal, sitting in a puddle of faint yellow urine and a small, cute lump of poop lay below her butthole.

Fluttershy weakly lifted her head up eyes focusing on Rarity. A deep red blush blossomed across her face as she saw her friend gawking at her. With a tiny "Eep!" she hid behind her mane as she she could, squeezing her hind legs shut.

The white unicorn shook her head to get out of her daze, a small smile lighting up her features as she saw Fluttershy return to her more normal, shy state. She stood, and quickly lit her horn, casting a small cleaning spell on herself, before turning to the pegasus.

"Fluttershy, dear," she said softly. "It's okay, we have to get out of here now though. We don't want these lovely sisters to find us, now do we?"

The threat of being caught in this state by someone other than her close friend was seemingly more embarrassing than her current predicament, because Fluttershy quickly shot a terrified glance at Rarity, before standing up herself. She let out another embarrassed yelp as her tail met a small resistance, and she noticed the turd lying on top of it.

Rarity smiled softly and casted the cleaning spell again on the floor, the puddle of piss dissolving away. However, she lifted Fluttershy's poop in her magic, and smiled devilishly as she gently placed it in a nearby potted plant. Then, she gently grabbed one of the pegasus' wings with her magic, pulling it out to it's full span.

Fluttershy did her best to hide behind her mane again as she saw the stained tips of her wings. Rarity's grin only grew wider however as she brought the wing up to her mouth, and slipped the tip in. Her tongue flicked around it as she tasted her friend's anal residue, eyes half lidded as she stared into the pegasus' eyes.

Somehow, Fluttershy's face managed to flush an even deeper red as Rarity suckled on her wing. Finally, the unicorn withdrew the wing from her mouth, trapping the very tip in her teeth and gently pulling, just enough to cause a little discomfort before releasing it. The appendage fell limp at Fluttershy's side, and Rarity flashed her horn once more, magically cleaning the rest of her feathers.

"Come on," she whispered conspiratorially. "Let's go back to the waiting room before they notice!"

Fluttershy watched her friend as she sneaked away towards the front of the spa. She stood there, silent for a moment before she turned and gave one last glance at the two sisters inside the mud bath room kissing hungrily. Swallowing her lust and embarrassment, she slowly followed her friend back towards the entrance.

"Rarity and Fluttershy?" Lotus said as she stepped out into the waiting room. "We are ready for you."

Rarity put down the magazine she was reading, and gave the spa pony a smile as she gently tapped Fluttershy's side.

"Of course!" she replied as she stood. "Why, I've been needing a good spa day for quite a while now!"

Lotus gave the two ponies a smile as she turned around and led them in the back. Unbeknownst to her however, her tail was still flagged slightly, and both of her follower's eyes were locked onto her shit-stained butthole as they walked behind her.

I think I need a spa day. Sounds kinda nice after writing this...

An Extra Special Bonus Chapter

Rarity and Fluttershy sat in the bath quietly as the two spa ponies left the room and closed the door behind them. There was a few moments pause before Fluttershy looked over at her friend.

"W-we're actually..." she mumbled sheepishly.

"Yup."

"We're s-sitting in their..."

"Mhm."

The yellow pegasus trained her eyes back on the mud bath they were sitting in. Tentatively, she leaned down and sniffed the substance. It had the natural earthy smell she had come to associate with the outdoors, but there was a light undertone of something far more rank and sour.

Her nethers began to soak into the mud below her as her arousal returned tenfold. It did not matter that she had just orgasmed a few minutes before, she was just a horny again.

Fluttershy glanced over at a lump next to her that was a slight different color than the rest of the mud. She felt an overwhelming urge come over her, and she reached out a hoof, scooping it under and lifting it up. Sure enough, it was the coil of shit that Aloe had pushed out earlier, and it was still a little warm.

"Now what do you have there, dear?" asked Rarity slyly as she saw what Fluttershy was holding. The yellow pegasus squeaked and almost dropped the turd as the unicorn slid over next to her. "Mmm, correct me if I'm wrong, but that looks a lot like the steaming pile of waste that our friend Aloe squeezed out of her tight little bum."

Fluttershy blushed at Rarity's tone and the words she used. It was so dirty! But so, so hot. "M-maybe," she whispered, her voice barely audible.

"What was that? I didn't quite hear you, dear."

Fluttershy gulped and spoke a louder. "It is, uh, Aloe's p-poop."

Rarity grinned as she leaned even closer to Fluttershy. "I thought so," she said. "Now what are you gonna do with it?"

Fluttershy took a deep breath as she stared at the mound of soft horse shit in her hand. "I- I want to t-taste it," she finally confessed.

"Then go right ahead," came the whisper in her ear, Rarity's tongue slowly tracing along the edge.

Taking a shuddering breath, Fluttershy opened her mouth. She slowly extended her tongue out over her bottom lip, and brought the pile closer to her muzzle. The strong smell wafted into her nose, and she couldn't help but breath in deeply. A low moan managed to escape her throat as the odor overwhelmed her, sending sparks of pleasure shooting to her brain. Unable and unwilling to hesitate any longer, she brought the poop to her mouth, and ran her tongue over it.

She gagged. The taste was absolutely disgusting, and she couldn't seem to get it off her tongue. She scraped the organ against her teeth, trying to get the residue off, but the taste still lingered. So she did the only thing she could. Fluttershy gathered the saliva in her mouth, smacking her lips, and she swallowed.

Rarity moaned as she watched Fluttershy swallow. Leaning in, she gave the shit a lick of her own, smiling at her friend as she did so. "Doesn't it taste so dirty?" she asked sultrily.

Fluttershy nodded. "D-definitely dirty," she said. She swallowed again, her mouth feeling dryer than a desert.

"Need a drink?" Rarity asked, her voice practically dripping with suggestive undertones. Fluttershy blushed even deeper, quickly understanding what her friend was implying. Hesitantly, she nodded, licking her lips. Smiling, Rarity pressed her lips to a yellow cheek, before she stood up.

Fluttershy watched as her friend slowly turned around, the mud-covered rear now lined up with her face. A flash of blue magic later, and all of the mud vanished, and she found herself face to face with Rarity's tight pussy and anus. The light scent of arousal drifted up from the slit, but Fluttershy found her eyes locked on the wrinkled pucker. It was mostly white, with only a faintest hint of residue from the unicorn's past bathroom trips. She wondered what the hole tasted like, the lingering aftertaste of Aloe's shit growing on her.

"Are you ready?" Rarity's voice startled Fluttershy out of her daze, and she mumbled a quick affirmative. "Alright my dear, here it comes!"

Rarity's vaginal lips parted slightly as a dribble of urine trickled out. It quickly grew into a steady stream, splattering down into the mud just a few inches below. Fluttershy was transfixed by the sight for a few moments before Rarity spoke again.

"Don't be shy dear, and definitely don't let it go to waste!"

Fluttershy opened her mouth again, and slowly moved her muzzle into the stream. Instantly the salty taste of piss flowed over her tongue, and she found that she absolutely loved the taste of it. It was far less potent than the taste of poop, but just as dirty. Without any hesitation, the pegasus let her mouth fill up with the faint yellow fluid, before swallowing. She let her mouth fill up again

Rarity suddenly backed up, startling Fluttershy as the stream of pee suddenly soaked into her mane, and dribbled down her back. The feeling was warm and pleasurable, and she found herself sinking into it. However, the feeling did not last that long, and the shower gradually tapered back off to a trickle.

"Sorry my dear, but I'm no race horse," Rarity apologized. "I'm afraid that all I gooOH!"

Fluttershy, throwing caution to the wind had begun lapping at the faint trickle dribbling out of Rarity's pussy. Her tongue pressed into the wet cunt, dipping past the parted lips. Rarity let out a low moan as the tongue wiggled around in her slit, Fluttershy seemingly trying to clean out every last drop of urine. The yellow muzzle nuzzled into the pussy as Fluttershy kept licking. The taste of Rarity's fluids were delicious, and she felt as though she couldn't get enough. Her nose was now fully pressed against the anus above it, and she paused to take a sniff. The heavy musk filled her nose and she sighed, her eyes rolling back into her head as she practically sucked the juices out of her friend's cunt.

As the pegasus continued to lick at her pussy, Rarity felt Fluttershy's nose repeatedly bumping into her puffy butthole. She felt as the nose was suddenly pressed in deeper, and she heard her friend take a whiff and sigh before she continued to eat her out even more vigorously than before. Smiling as a dirty idea popped into her mind, she flexed her anus.

A wet fart ripped out of Rarity's asshole, right in Fluttershy's face. Moisture coated the tip of her nose, and the pegasus squeezed her eyes shut as the rectal wind blew against her. The rotten smell of shit flooded into her nose, and she coughed into the pussy. Another smaller toot slipped out, and the pungent aroma settled in a cloud around Fluttershy's head.

Overcoming her initial shock, the yellow pegasus found that the smell of friend's farts was incredibly arousing. Given how this spa trip was playing out however, she should not have been that surprised. She pushed her nose into the pucker, sniffing even more. It flexed against her nose, almost like it was giving it a kiss. Rarity seemed to be out of gas however, because no more slipped out.

Fluttershy seemed content with the heady musk of her friend's bare anus anyways. It was a more subtle stench than the gas, but pleasant all the same. And the pegasus was getting high off of it.

"Wow Fluttershy," Rarity cooed as her friend pushed deeper into her rear. "I didn't take you for such a brown nosing slut!" If the pegasus heard her, she showed no signs of acknowledgement. "Oooh, yes, right there my dear. Keep doing that and I'm going to cuUUUUM!"

Rarity quivered as Fluttershy finally withdrew her tongue from her pussy, marecum squirting out and drenching the yellow mare's face. Eyeing the pucker above the spasming pussy, Fluttershy dove back in, this time pressing her mouth to the wrinkled star.

The unicorn's knees wobbled, and she let out a coo as she felt her friend's tongue brush over her anus. Fluttershy slobbered over the hole, thoroughly cleaning whatever residue was there, from the farts or otherwise. The taste was tamer than licking Aloe's fresh shit, but the bitter undertone was still there. She pressed her tongue into the center of the rosebud, trying to unlock more of the potent flavor. But before she could, the rimjob was cut off as a door slammed.

"Oh my gosh!" cried out Aloe from the doorway, as Rarity whipped her head to look at her. Fluttershy tried her best to bury her face in Rarity's ass, which was not that unpleasant for either of them. The white mare held back a moan as her friend's muzzle slipped almost entirely inside her still gaping cunt.

"I am so sorry, I did not realize... um," the pink mare blabbered out, her face flushing an even deeper shade. She tried not to stare at the unicorn's ass, but failed miserably.

"Uhhhh..." blanked Rarity, not really knowing exactly was the right thing to say in this very moment. "She's, um, helping... me... clean?"

That was not the right thing to say in this moment.

What, did you think I wasn't going to make them fuck in the mud bath?
