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.
