Don't Stain The Bedsheets, Bro
On any normal day, Twilight Sparkle was usually the only princess in Ponyville. However, there were certain exceptions that occurred from time to time, and today happened to contain one of those exceptions. There were two extra guests of royal proportions in town this weekend, and the rest of Equestria's royalty would be joining later. Princess Cadence and Shining Armor were enjoying a lovely week in town, having had the advantage of being related to Ponyville's resident princess.
The room they had in Twilight's castle was the very pinnacle of luxurious. It had a bed far larger than a size that anypony could get in a store, a bathroom that included a waterfall, and even a full living area complete with way too many couches for the number of ponies that could comfortably live in the room.
Twilight Sparkle approached that room now, ready to wake up the couple to get them ready for their final day of vacation. She approached the opaque crystal doors, nodding to the guards standing on either side. They both returned a curt nod, remaining at attention guarding the doors. Smiling to herself, Twilight knocked on the door, ready to wake them up.
KNOCK KNOCK KNOCK!
The lavender hoof rapped against the door three times in quick succession. After a brief pause with no response, Twilight knocked again. Still, nopony came to the door.
"Ahem." Twilight's attention was drawn to the guard on her left who coughed. "There was a soundproofing spell set up last night. I don't believe that they ever took it down."
Twilight's cheeks flushed as she let out a weak chuckle. "Oh, heh heh." She was a bit more hesitant to enter the bedchambers now that she had an idea of what had been happening. But there were plans in place for today, and without any further delay, Twilight used her magic to swiftly unlock the door and quietly push it open.
The inside of the guest suite was dark, lit only by the daylight filtering through the drawn curtains. Silently shutting the heavy door behind her and re-locking it to prevent any unwanted disturbances while Cadence and Shining were getting ready, Twilight opened the curtains to light the living area up some. The lit up room revealed that the door into the actual bedroom area was slightly open. The alicorn trotted over there, opening up curtains and adjusting the room as she made her way to the doorframe.
As she approached the door, a peculiar scent began to drift into her nose. She sniffed at it, trying to figure out what it was. It got stronger as she approached the door, until it became slightly overpowering. Twilight almost gagged at the sheer power of the rancid odor as she pushed the door fully open. It was quite clear that the scent's origin was in this room, and just was Twilight went to turn the lights on, she identified it for what it was. Cadence and Shining Armor's bedroom smelled like literal shit. The lights flew on, and it took the lavender pony a few moments to figure out exactly why that was. Her jaw quickly went agape as she took in the scene before her.
The bed was in a state of complete disarray. Cadence and Shining were entangled between one another, their legs inter-wrapping around each other awkwardly in a way that Twilight couldn't believe was even remotely comfortable. Cadence's plot was facing the door, her tail off to the side and revealing everything to her sister-in-law. The pert anus was darkened with past excrement, and brown streaks trailed off the side of her flanks. Dried arousal caked her vaginal lips, and the sheets around her pussy will still damp with cum and other bodily fluids. Shining's pristine, white coat shared similiar brown stains, present all over his body. His rear end was also facing Twilight, and his formerly white butthole was also stained with crap, an actual log of shit lying on the bed next to his tail. The sheets surrounding the two were also completely riddled with shit stains and turds of various consistencies. They were spotted with puddles of stale piss and dired streaks of cum. Shining's marbled dick lay draped over one of Cadence's rear legs, its head dipped in one of the pools of urine.
Twilight was aghast at the disgusting sight before her. Or, at least she thought she was. Her eyes widened and she let out a Fluttershy-esque "EEP!" as she felt a drop of arousal trickle down her leg. Holding her plot up to a mirror, she watched in fascination as her vagina winked repeatedly, her clit flicking in and out of her lips. Her level of arousal surprised herself, as she didn't think anything like this was inherently sexy.
"It's hot, isn't it?" a voice whispered to her from the bed.
The alicorn's head spun around to see Cadence staring at her, eyes half-lidded with either sleep or lust. "C-cady!" Twilight sputtered. "I didn't meant to... I was just... W-wake you up..." She then realized that Cadence could most likely see her dripping wet snatch in the mirror behind her, so she plopped down on her haunches, smashing her plot into the soft carpet of the floor.
Cadence let out a soft chuckle at her sister-in-law's embarrassment. "Oh, Twilight," she cooed. "Don't even try to hide it from me. You're so turned on right now, you're practically radiating lust!"
Twilight shook her head. "N-no! That's not at all... I mean..." she sputtered, trying to form a sentence as Cadence hopped off the bed and sauntered closer, her sister-in-law's tail waving enticingly.
"Mhmmmm…" Cadence licked her lips. "It's soooooo dirty, isn't it? Seeing your brother and I covered in each other's filthy shit." Twilight gulped, the pink alicorn was only a few paces away. "Our coats stained brown, and that smell!" Cadence took a deep whiff, and Twilight found herself involuntarily mimicking the action. "Oh that smell, its so disgusting and vile!" The two alicorns were now only a hair widths apart, their muzzles practically touching. "Don't you just want to get down and dirty with us? Don't you want to satiate that burning need between your thighs?"
In her lust-filled haze, Twilight Sparkle could only utter one word: "Yes."
Cadence's horn glowed as she closed the distance and planted her lips on Twilight's. The lavender pony's eyes widened as a tongue entered her mouth, a faintly bitter, earthy taste coming along with it. Cadence's horn stopped its glowing, and Twilight suddenly felt a new, overwhelming presence pushing at her sphincter, causing her to lift her butt off of the ground in panic. She stared into Cadence's half-lidded eyes and the pink alicorn pulled away, only to say, "Just let it go."
The confirmation was all she needed as Twilight let out a short grunt and her anus opened wide. Cadence pulled her back into a kiss to silence her, her oral organ slipping right back inside. Half-solid logs of horse shit slid out of the purple pucker, falling to the floor below as the two ponies explored each other's mouths. Unable to resist the temptation any further, Twilight reached a forehoof between her legs and began rubbing at her pussy as she continued to poop onto the carpeted floor.
With a moan, Cadence pulled away from Twilight as her horn glowed again. The older pony fell away onto her back, spreading her legs wide and exposing her privates. Her pink pussy, lips flushed red with arousal, winked at Twilight as the anus below it squeezed out a thick turd.
Having finished emptying what Cadence had magically placed in her colon, Twilight quickly leaned forward and began slurping at that waiting cunt. The heat of the horseapples being made right below her heated up her chin as Twilight dug her tongue deep into Cadence's baby cave.
A dry fart signaled the end of Cadence's bathroom break, and Cadence's magic gently pushed the eager young alicorn away. "Why don't we move this up to the bed?" she suggested with a smirk, and Twilight nodded rapidly, panting.
The scent of the room had changed drastically with the addition of the new waste, no longer stinking of stale shit, but now smelling like a freshly-used outhouse. This change in olfactory stimulation only made the two alicorns hornier as they climbed onto the stained sheets of the guest bed. Shining Armor shifted lightly as the weight distribution changed, but did not wake.
Without a moment's hesitation, Cadence and Twilight resumed their make-out session. Twilight positioned herself on top of the pink alicorn, their lips not separating as their tongues slithered around inside the shared space of their mouths. Twilight was vaguely aware of Cadence once again casting a spell, and moaned as an intense pressure suddenly filled up her bladder.
Piss literally exploded out of her urethra, spraying onto Cadence's belly. Streams of it trickled in between her tits, and ran over her clit before pooling on the sheets around her dirty anus. Twilight separated from their make out session to take breathe, the sheer pressure being released pushing her over the edge. She convulsed on top of Cadence, her urine stream breaking off sparratically as her vagina clenched over and over again.
Before her orgasm was finished Cadence had flipped her over, and leaned down to slurp at Twilight's twitching pussy. The lavender mare moaned as her orgasm subsided into her sister in law's talented tongue work and her piss began to flow out steadily again. Cadence kept her mouth open to accept the salty fluid, waiting until her mouth was full to pinch her lips and spray it out onto Twilight's chest and face. The alicorn on the receiving end let her face slip into momentary disgust at her own urine being spat at her, but that feeling quickly dissolved into even more arousal as a few drops leaked into her mouth.
With Twilight's bladder finally beginning to run dry, Cadence gargled what she had left in her mouth before swallowing, a scene which made Twilight lightly moan. Licking her lips seductively, the Princess of Love then leaned back in to the sopping wet cunt in front of her.
Cadence's tongue went to town on Twilight's dripping snatch, teasing around the outer lips before plunging into the depths of the love tunnel. Succulent juices leaked into the mare's mouth as she worked, the moans above her signalling she was doing a good job.
As she ate her sister in law out, Cadence caught a whiff of Twilight's quivering butthole, right below her mouth. She grinned devilishly as a dirty idea popped into her mind.
Reluctantly, the pink alicorn pulled away from the pussy in front of her, Twilight letting out a needy moan at the sudden lack of vaginal stimulation. Cadence's eyes settled on the purple anus, smudged over with the leftovers of Twilight's creamy brown shit from earlier. Her mouth almost watering for a taste, Cadence wasted no time, and dove in.
Twilight let out a startled yelp at the sudden anal attack, but quickly melted into a state of pleasured moans as Cadence orally cleaned her dirty pucker. The gentle tongue dug through the fresh layers of filth coating the anus, ministrating the wrinkled skin beneath it. The filthy taste of Twilight's poop took over her senses, and she moaned into the purple ass, trying to get her tongue deeper and deeper into it. For the pony on the receiving end, the thought of somepony licking shit off of her behind was as arousing as ever, and she had the sudden urge to try it for herself.
The lavender alicorn looked to her right, her eyes falling upon the rear end of her brother. Shining Armor's anus still boasted the crusted-over remains of his and Cadence's previous filthy escapades. She scooted herself closer to his backside, Cadence glancing up and smirking before following Twilight's scooting tush as the pony lined her muzzle up with her brother's ass.
Upon closer inspection, Twilight realized that most of Shining's rear end was caked with shit. Flecks of poop dotted his ballsack and brown stains matted down his fur in clumps around his taint. Twilight had a good idea of what went on between him and Cadence last night, but seeing the damage now, it was almost unimaginable. The stink of shit wafted from her brother's asshole as her passed a quiet fart in his sleep, and Twilight inhaled deeply. Lust finally overtaking her senses, the alicorn extended her tongue and braced herself for her first taste of feces.
A bitter taste flooded into Twilight's mouth as she licked across the dirty anus in front of her. It took all of her willpower not to initially gag as she pulled her tongue away. With the way Cadence was going to town on her own turds, she didn't expect quite the powerful flavor she got, but she presumed it was an acquired taste. The thought of what she was doing however, sent a strong quiver through her loins, and despite the disgusting flavor, she went in for a second taste.
The second lick sent a shiver down Twilight's spine as the flavor of shit once again entered her mouth, but she didn't pull back this time. Instead, she continued to lap at the puckered orifice, cleaning it of the dried poop coating it. Shining let out a quiet moan in his sleep as his sister cleaned his ass, but didn't yet wake.
Cadence took notice of Twilight's new position, and pulled away, squealing inside at this new development. As the Princess of Love, she encouraged any and all forms, and incest was one she unfortunately rarely saw. Especially incest this kinky. To watch as a sister ate out her brother's shit-stained asshole was almost overwhelming for her, and she dug her hoof into her pussy furiously as she watched. If only Shining could reciprocate the actions of his sister...
Grinning, Cadence stood up on he hind legs and magically filled her bladder as much as she dared. She waddled over so that her dripping slit was hovering over Shining's sleeping form before sighing, and letting her urine spew forth from her pussy.
Fresh piss rained down upon the white unicorn, almost instantly drenching him. Cadence waved her hips back and forth, marking his body not unlike a dog would, even focusing her stream to get some trickles running down into his crack, allowing Twilight to get a taste of her pee as she continued to lick all around her brother's pucker and taint. Bringing her stream back up the body, she finally let loose her full torrent into Shining's face.
The piss spraying over him finally stirred Shining Armor from his deep slumber. "Huh?" he asked confused as the taste of his wife's urine permeated his mouth. The comforting feeling of a tongue cleaning out his butthole was present as he was pulled from the depths of his sleep. He smiled, squinting up at the sight of Cadence's spraying cunt above him, he mouth opening to accept some of the golden nectar.
"Starting early today, are we?" he asked, gurgling through a mouthful of alicorn pee. He heard Cadence groan above him as her bladder ran dry. Wait a minute. If Cadence was above him, who was rimming his asshole?
Shining awkwardly twisted his neck to look towards his rear, seeing a pair of lavender wings and a familiar purple horn poking up above his flank. "T-Twily?!" he exclaimed, startled.
Twilight raised her head, grinning at him through shit-stained lips. "Hey, bro." She immediately went back down and sucked one of his dirty balls into her mouth, eliciting a restrained moan from him.
"This is so wrong," he groaned as Cadence squatted over him.
An wet fart sputtered out from the pink pucker above his face as Cadence replied. "Oh just relax and enjoy it, Shiny." With that said, her anus opened up and a torrent of wet slop poured out over his face.
Giving in to the raging boner between his legs, Shining let go of all his restraint and accepted his fate. Sure, his younger sister was literally cleaning his own poop off of his balls while his wife squirting out her liquid shit on his face, but worse things could happen. Without any further refrain, he opened his mouth and let some of Cadence's diarrhea into his maw.
Twilight glanced up and watched as her brother let Cadence's shit fountain pour into his mouth and she moaned, burying her muzzle back into his asshole. "Cadence!" she cried. "Make him poop in my face!"
Cadence grunted as a pocket of gas slipped out of her anus, the trumpeting fart sending small globs of her wet scat flying all over Shining's already stained coat and the bed. A speck of hit hit Twilight's face right on the tip of her nose, and she accidentally snorted a portion of it up her nostril. The scent of Cadence's magically induced diarrhea burned into her nose and Twilight wriggled her muzzle at the sudden overwhelming stench. She coughed as she stuck her tongue out and tried to lick the rest of it off of her face.
"You want it, unnnnnng, wet or hard, Twilight?" asked Cadence as she forced another wet fart out, another volley of liquid shit spraying out around her.
"Wet!" moaned Twilight in reply, digging back in to Shining's nearly clean butthole.
Cadence quickly obliged, her horn glowing and filling Shining Armor's bowels to the brim with wet, sloppy poop. His anus quivered at the sudden pressure, before his load, too exploded into his sister's face. Twilight let out a high-pitched squeak as hot diarrea squirted into her mouth. The taste was nothing like she had experienced previously with his crusty pucker. The fresh poop was far more potent in flavor, and Twilight could only compare it to something hot or spicy. It still had that bitter flavor, but it was masked by something more sour and even more disgusting than before. This time, she couldn't hold it back as she gagged on the flavor.
As disgusting as her brother's liquid shit was however, it was even sexier than before. Twilight was unable to resist the urge to stuff a hoof down in between her legs, and so she didn't. She rapidly rubbed her hoof over her soaked cunt as more and more of Shining's wet slop oozed out into her mouth.
This went on for some time before he was done, and Twilight pulled away, letting out a grotesque-sounding burp, the flavor wafting back up her throat. Shining squeezed his rectum one more time, pushing out one last glob of shit onto the bed behind him, the liquid poop sliding over his taint and balls, once again coating them in his shit. Twilight, as if it were routine by now, just went right back in and began licking the diarrhea off his testicles again.
Shining, in the meantime, stuck out his tongue as Cadence's rear end descended upon his face, and he began to give her a dirty rimjob as she ground her ass into his muzzle. "Oh yeah," she moaned, another fart ripping directly into his mouth, and even more flecks of shit flying out. "Eat my dirty ass you naughty horse fucker!"
Twilight, having had enough of her brother's ass, nuzzled her way between his legs and began lapping at his throbbing shaft. Shining moaned at the new stimulation, shifting to give his sister better access to his cock. His moan vibrated in his wifes asshole causing Cadence let out a moan, and her pussy to begin reflexively clenching as another orgasm fought its way out of her. Her cunt squirted marecum over Shining's chest and Twilight's mane as her hips rocked. As her orgasm subsided, she fell and rolled off of her husband's face, breathing heavily.
Twilight in the meantime, continued to go down on her brother's dick. She took the tip into her mouth and suckled on it, drawing a moan from deep in Shining's throat. "N-no offense Twily," he stammered. "But I kinda need to put it in something right now!"
The lavender alicorn grinned up at him and giggled airily, giving the penis one last loving lick before backing away and turning around. She flipped her tail out of the way, revealing her dripping cunt and tongue-cleaned pucker. "Will this do?" she asked huskily.
Shining practically drooled as he openly gazed over his sister's plot for the first time. Sure, he had snuck glances over the years, but she had never so boldly revealed herself to him in this way before. "That'll do, Twily," he mumbled. "That'll do."
He quickly reared up on his hind legs, and positioned his shaft. Twilight gasped as the head of his penis brushed against her winking clit, before the length slipped inside. Both brother and sister let out a simultaneous loud moan as Twilight's virgin slit was stuffed for the first time, and her brother was the one to do it.
"Oh yes!" cried Twilight. "Breed your slutty sister, big brother!" She reared her hips back into him, sending him balls deep into her tight cunt.
Cadence sat off to the side, idly rubbing her own pussy as she watched Shining fuck his sister. She could only think of one thing to make it hotter. Her horn lit up, and Twilight suddenly let out a loud grunt. "Oh fuck! Shining! I'm going to shit all over your dick!" she screamed as she did exactly that.
A semi-soft turd began to slip out of the purple anus, smearing onto Shining's crotch as he pistoned his shaft in and out of her eager slit. The scat slid down, past his dick and fell to the bedsheets below her. Another log began to slide out and Shining used a hoof to push it towards his penis, the shit landing on it and smearing into her cunt as he continued to fuck her.
Twilight moaned at the sudden addition of the semi-soft crap in her pussy. It was a strange feeling, but the knowledge of what it was is what added to the sensation.
Both ponies were very close to cumming, Shining humping faster and faster as Twilight continued to shit out logs of soft crap. Soon, the entire area between Shining's crotch and Twilight's ass was a mucky mess of smeared scat and love juices. With a grunt, Shining felt his balls tighten up, and he slammed home into the pussy clenching around his cock. Cum erupted from his penis directly into his sister's womb.
The sensation of her brother filling her up with his seed pushed Twilight over the edge, and she came as she squeezed the last turd out of her pucker, curling up against Shining's belly. Her juices squirted out around his dick and rained down onto the pile of poop below, soaking into it. The two just sat there panting for a while before the unicorn stallion pulled away, his softening cock slipping out of Twilight's shit stained cunt. A glob of creamy shit slid off of his limp cock and joined the pile below.
He smiled lightly as he felt Cadence fill his bladder, and took hold of his cock in one hoof. He took aim, and let loose a stream of piss onto Twilight's dirty plot.
Twilight sighed in pleasure as she felt Shining's urine spray onto her rump, the force washing away chunks of the mucky poop stuck to her backside. She moaned as he adjusted the stream to hit here right on her butthole, the hole twitching under the new stimulation.
Cadence crawled in between the siblings, under Shining's stream. Urine sprinkled down into her made and face and she scooped up a large amount of excrement from the pile, mixing it with Twilight's marecum and Shining's piss before crawling around to Twilight's front side. Holding the glob of shit in her hoof, she held it up to Twilight's mouth. "It's only fair that you get a taste of your own, Twilight."
Twilight nodded with a shit-eating grin before leaning forward and pushing her muzzle into the pile. Cadence giggled at the young alicorn's lazy licking, before she too leaned in and licked at the muck herself. Twilight moaned into her own shit as the impact of Shining Armor's urine against her anus was replaced with his tongue.
Cadence suddenly pushed her hoof forward, the soft scat smearing into the alicorn's face. Twilight let out a surprised gasp as her sister-in-law cackled, before she too joined in. Twilight reached up with a hoof and pulled Cadence forward into a messy prench kiss, the poop smearing onto her pink muzzle as well. The two moaned into each other's mouth as the slurry of shit, cum, and piss spread around their faces like dirty, brown makeup.
Shining pulled his head out of his sister's messy ass, his face also smeared with the sloppy turds of Twilight's plot. "This was fucking hot," he exclaimed, falling back.
The two mare separated and crawled up to lay next to him. Cadence gave him a dirty peck on the cheek, leaving behind a brown lipstain. Twilight nuzzled up against his other side, her own shitty face smearing into the crook of his neck.
"I love you, BBBFF."
"I love you too, Twily."
"Don't forget about me!"
"I love you to, Cady!"
The two guards really didn't quite know what to make of the long time Twilight spent in the suite with Princess Cadence and Prince Armor. It wasn't their job to know. However, when two more ponies showed up, it only piqued their interest more.
"Guards," said Princess Celestia as she and her sister approached. "Are Princess Cadence and Shining Armor still in their suite?"
The guard on the left curtly nodded. "Yes, your highness. Princess Twilight entered almost an hour ago, and she too has not left."
Luna raised an eyebrow. "Princess Twilight is in there as well?" The guard nodded in affirmation.
Celestia sighed. "Well, they're late for our meeting. It's nothing that can't be postponed, but I'd still rather it not be."
The guard shifted uncomfortably. "I- I don't know what to tell you, your highness," he said nervously. "Nopony has left the room."
With a roll of her eyes, Luna stepped forward. "Step aside, Guard," she ordered. "We shall investigate." With a flick of her horn, the door unlocked and opened. The two princesses stepped forward and into the suite.
"Your highnesses," the other guard said. "Shall we accompany you?"
"There is no need," came the reply of Celestia, before the door closed and locked behind her.
As soon as they entered the suite, the princesses had some inkling of what happened in the other room. The stench of scat and sex was almost overpowering in the room, and both Celestia and Luna's slits were already dripping with lust. Not even skipping a beat, the two alicorn's quickly walked over to the bedroom, and pushed the door open to reveal the sexiest sight they had ever seen.
"Luna," said Celestia softly as she gazed at the shit-covered room containing the sleeping trio. "Cancel our meetings for the rest of the day. I think there's something far, far better to attend to."
"Of course, Celly," replied Luna, licking her lips as the two approached the bed.
