Celestia and Luna were sitting across from each other at the relatively small dining table in their royal chambers.

"What?"

"Come on, Lulu, it'll be fun."

"I know it will be fun, sister, but what will everypony else think?"

"Blame it on Twilight."

Celestia's horn was aglow with a golden aura, which matched the sliver of magic teasing her sisters dripping, wet pussy.

"I don't think Twilight is the- ah- exhibitionist type. They won't believe it..."

"They don't have to. They just don't need to know the truooOOO- AH!"

Luna's horn lit up with her own glow as she suddenly shoved a thick, thaumaturgical phallus into her sister's equally dripping snatch.

"H-how about we limit our activities t-to j-just my bedroom- oh my Celly keep doing that!" 

"Fine."

Celestia's horn died down, and Luna was left panting in her seat. She too, removed the magical dildo from her sister's pussy.

"Celly!" she huffed. "I told you not to stop!"

Her sister just smiled smugly back at her. "I thought you wanted to move onto the main event," she replied.

Luna grinned back, and stood, turning away from the table and heading towards the door. Celestia followed closely, watching as Luna's tail flicked up over her back, presenting her pronounced pucker and leaking pussy to her sister. They walked down the hall passing by Celestia's chambers, and instead heading towards the younger sister's. Upon reaching the door, Luna paused, glancing back over her shoulder to make sure her sister was watching. Then, she winked her anus and clit, letting a dribble of her fluids leak out onto the tiled floor below. She smiled in satisfaction as Celestia let out a low moan of lust, and opened the door to her bedroom.

She headed over to the bed, rocking her hips with every step, and never letting her tail fall back down. Upon reaching the bed, she placed her forelegs on top of the mattress, and leaned forwards, eagerly presenting her hindquarters to her sister. "What are you waiting for, Celly?"

Celestia, not knowing the answer to that question, stood and approached her sister. "I don't know," she said. "But I do know what I'm going to do now..." 

The alabaster alicorn leaned down, bringing her muzzle close to Luna's exposed privates. She took in a deep sniff, letting the scent of her sisters arousal flow through her nostrils, followed by the musky smell emanating from the dark anus above the wet slit. Practically drooling, Celestia wasted no more time.

Luna let out a deep moan as her sister's tongue made a broad sweep over her marehood. The wet organ slithered its way inside her puffed-out lips, parting them, and licked around. Luna's clit flicked out, and Celestia quickly snatched it up, drawing it into her mouth and sucking on it. This action only caused Luna's moans to get louder, and her rear legs to shake slightly as the fought to keep her up.

Having had enough with the wet snatch for now, Celestia trailed her tongue upwards. It slid up along Luna's pussy, before making a dainty lick around the rim of her pucker. The hole quivered at the new attention, and Celestia watched as Luna's tailhole clenched on something that was there. Smiling, the alicorn dove in, slathering her saliva all over the tasty ponut before her. 

Celestia let out of a moan of her own as a slightly bitter taste hit her taste buds. "Oh, Luna," she moaned, as reached a hoof beneath her own parted legs and began to gently glide up and down her own slit. Having enough of the outside of the alicorn's butthole, Celestia finally positioned her tongue at the center, and slid it into the puckered orifice.

Luna grinned and pushed her rear back against her sister, grinding Celestia's tongue even deeper into her rear entrance. "You like getting a deep taste of your younger sister's ass, huh?" she taunted between her gasps and pleasure-filled moans. Celestia moaned her affirmation directly into Luna's parted ponut, wrapping her hooves around it to pull it even closer to her face. She somehow buried her muzzle even further between those two, wonderful cheeks and started rapidly flexing her tongue in and out of her sister's asshole.

"Oh, Sister!" Luna cried. "C-careful! You keep doing that and I may j-just CUUUUUUM!!!" The alicorn's sentence trailed off in a cry of moans and pleasure as her pussy erupted with mare juice, spraying out against Celestia's neck. After two or three spurts, the torrent of femcum trailed off to a low trickle. 

Luna panted, her head collapsing to the bed. "I hope you're ready, Celly. I think that loosed the floodgates..."

Celestia raised an eyebrow. "Oh really," she replied sultrily. "Feeling kinky today, I see." The Princess of the Sun rose back onto all fours, now standing over her sister's flank. "Roll over," she commanded.

Her younger sister obeyed, rolling over onto her back, and pulled herself fully onto the bed. She spread her rear legs outward in a "v" shape, so that her tail draped off the edge of the bed, and her dripping pussy and plothole were exposed to Celestia's dominance. 

With everything presented directly to her, Celestia lay back down so that her head was right above the wet snatch. "Do it," she said. "Let it go."

With a lustful moan, Luna obliged.

It started as a trickle, but within seconds, a jet of urine was spraying out off Luna's pussy and right into Celestia's face. Almost surprised by the sheer force behind the stream, Celestia was caught off guard. Quickly recovering, she opened her mouth wide, and took in as much of her sister's piss as she could.

Celestia moaned, the sound coming out as more of a gargle, as she reached a hoof down, and began rubbing herself furiously, trickles of Luna's piss dribbling down around her own white, leaking pussy. Luna herself let out a moan of release, turning into one of pleasure as her sister sprayed and arc of it onto her stomach and breast. 

Luna's piss was flying everywhere as it impacted Celestia's face, drenching the royal mane and face, and leaving long, wet trails of it down the white furry torso. Dribbles of it ran down Luna's rear, as well, dripping down the rest of her pussy and flowing in small rivulets over her dark pucker, finally pooling around her dock and soaking her tail. The sheets around her flank were drenched as well as the carpet between the two incestuous sisters.

After some time, the force of pee leaving Luna's slit slowly began to die down, causing Celestia to lean in and press her mouth directly to her sister's pussy, letting the salty flavor of her piss drench over her tongue. As the stream petered off completely, the alicorn resorted to licking the pussy up and down to get the last few dribbles of it, going all the way down and circling around the tight little anus below as well. On the receiving end, Luna let out a coo of pleasure as her sister's tongue caressed her tight asshole once more.

"Mmmmmm," Celestia hummed, savoring the flavor of Luna's urine in her mouth. "Got anything else tasty for me today?" she asked.

"Maybe," came her sister's reply. The anus in front of Celestia's face flexed outward, along with a brief pass of gas. The alabaster alicorn grinned and leaned in, planting a deep kiss right on the pucker, as the faint smell of Luna's waste flowed around her. "But maybe I want something from you, first."

Celestia raised an eyebrow as Luna leaned up and pushed her back, away from the lunar craters. "Oh? And what do you want from me?" she asked as Luna crawled off the bed, and stood over her. 

The younger alicorn grinned and leaned down so that her face was inches away from Celestia's. "You got to drink out of my today, so how about you let me drink out of you." She emphasized her point by poking her sister's chest with the tip of her forehoof.

"Well that sound's fair enough to me," Celestia replied with a wide grin. "But don't you think we can get a better position?" 

Luna's magic quickly surrounded her, and she found herself on top, literally sitting on her sister's face. "Will this work?" came her voice from below.

Celestia's grin somehow got wider. "Like a charm."

Luna too, smiled as she stared up at her sister's wet slit and anus. Unlike her own, however, Celestia's pucker was darkened by remnants of her past trips to the porcelain throne. Wanting a bit of an appetizer before the main course, Luna reached her tongue out and ran it over the surface of the dirty plothole.

The white alicorn grinned, as she knew exactly what her sister was doing. Deciding to appease her some more, she pushed her rectum, letting out a wet-sounding gust of anal air onto Luna's tongue. Below her, her sister moaned as the rancid air blew directly into her mouth and on her face, a few specks of fecal matter joining the blast.

She pulled back for a moment. "Oh, Celly," she said, licking her lips with a moan. "How long has it been since you cleaned back there?"

"Only since last time, dear sister," came the reply. "A few days."

Luna let out another moan, back arching as more juice leaked out of the dark-blue snatch. The knowledge that she was licking literal shit that had been on her sister's ass for days was so hot to her. She leaned back up and continued eating out Celestia's dirty asshole, caking as much of the remaining crap on her tongue as she could.

She head Celestia sigh above her, and then felt the beginning dribbles of a stream flowing down onto her neck. The stream then trailed outwards until her sister's urine was arcing onto her lower stomach. Trails of it dribbled backward along the alicorn's taint to Luna's mouth, where she could then lick it up. She wasn't to saddened by not catching the full stream of piss in her mouth, as she got a good taste of it down here, the flavor mixing with the bitterness of Celestia's shit. Besides, with the way the stream was placed, it was very close to her-

"AHHHHHHH!" Luna let out a cry of pure pleasure as Celestia adjusted her stream of pee for it to land directly on her exposed clit. She experienced her second orgasm of the night within seconds of the intense pleasure, another dose of her mare cum squirting across the room, and splattering on the wooden floor in a surprisingly large puddle. Luna kept squirting however, another spray of her marecum drenching the floor even more. 

Celestia relaxed her stream, giving Luna a chance to catch her breath. She watched with satisfaction as another squirt of her sisters juices sprayed out from between those hind legs. 

Luna lay her head back and closed her eyes, breathing heavily. She let out a soft moan as her sisters piss pooled on her belly, and lifted a hoof up to let it rest there. She felt the stream run over her fetlocks as it slowly began to come to an end, it's impact trailing up until it dripped onto her muzzle. With a pleased smile, Luna opened her mouth to let the pee in, and let it tickle calmly down her throat, savoring the salty flavor as Celestia had done with her own.

She heard a putter above her, and a rush of air blew against her forehead and horn. She heard her sister call "Look out below," before she opened her eyes. 

Above her, Celestia's dirty anus was slowly spreading open to reveal the head of a log. "I hope you don't mind, Lulu, but I have more to contribute." Luna grinned up at the sight of her older sister crouching above her, pussy dripping hot urine, and a turd slowly making its way out of her pucker. 

Celestia pushed on her rectum harder, letting the log slide out more. It gained momentum, reaching almost a foot before it slipped out completely, falling with a wet splat onto Luna's waiting face. The white alicorn moaned at the sudden feeling of emptiness as her anus closed slightly, but kept pushing, as there was definitely more left in her bowels.

Below her, Luna let out a moan of her own, before reaching a tongue out and licking at the log of shit draped across her muzzle, tasting the bitterness of a fresh load right on her mouth. 

The white alicorn kept pushing, sighing as a nugget reached her sphincter. With a quick flex of her anus, she popped it off, and watched below as it fell directly into Luna's waiting mouth. Luna let out an even louder moan as the nugget fell in her mouth. She let it rest there on her tongue for a moment, absorbing the flavor before biting into it and letting the more rancid, pungent flavors erupt in her mouth. As she chewed the nugget, another, smaller log fell onto her, this time sliding off her face and landing more on her neck. It left a dark smudge of brown where it slipped off, matting the navy fur down with it's thick muckiness. 

Celestia pushed, feeling that her colon was now empty. A wet fart slipped out, spraying a few loitering pieces of crap clinging to the rim of her butthole onto Luna's face down below. Luna swallowed the muddy nugget in her mouth, and leaned back up to lick her sister's freshly dirtied anus clean. The log resting on her face squished up against Celestia's cheek as she leaned in, before sliding off to the ruined carpet below. 

Luna let her tongue wipe down her sister's pucker before going inside the still slightly gaping hole. There was still a lot of fecal residue left inside the rectum, and the dark blue alicorn was all too happy to clean it out for her. Celestia gave another push to make sure there weren't any large logs or nuggets left inside, and in doing so, a short burst of urine sprayed out over Luna's torso. Her bladder and colon emptied, Celestia let out a moan as Luna licked the last of the poop from inside of her.

"I hope you know we're not done yet," Celestia said as her sister pulled her tongue from her ass. "You still promised me a meal of my own."

Below her, Luna smiled. "I haven't forgotten, Celly," she replied. "As a matter of fact, I've been having a hard time holding it in down here."

"Oh have you?" Celestia smiled as she got up off her sister's face. Her horn glowed. "Why don't we mix it up a bit then, for added suspense?" Her crotch glowed the golden color of her magic, and a long, thick horsecock slowly slipped out of her pelvis, followed by a low-hanging pair of plump balls. "How does this look to you?"

Luna licked her shit-stained lips as she eyed the already stiffening rod and orbs. "Really bucking sexy."

She too stood up, the turd laying on her neck falling to the floor with a wet thud. She went back over to the bed, and assumed the position she had before, on her back with the pussy presented to her sister. Celestia sat in front of the bed, her stiff cock pointed towards the ceiling, and face inches away from Luna's clenched asshole. With a groan, Luna relaxed her anus, and pushed.

Her shit was wet and sludgy, significant of all the fiber she had been eating lately. It flowed like a river of mud over her dark blue tail, and fell off the bed with wet splats. Every so often, a pocket of gas would come out as well, sending specks of her liquid shit flying into Celestia's face and mane.

The white alicorn seated in front of the show let out a loud moan as a large glob of Luna's diarrhea landed on her fully erect cock. Unable to help herself, Celestia quickly stood, and positioned her cock at her sister's open backdoor. Placing two hooves on the bed either side of Luna, she trusted forward, moaning as the hot, muddy poop flowed over the head of her throbbing penis.

Luna let out a startled groan as her asshole was suddenly plugged by Celestia's thick rod. Taking a deep breath, she pushed harder, letting more of her crap squeeze out around the dick in her ass with loud, wet noises. She moaned in pleasure as Celestia began pistoning her cock in and out of her butthole, wet squelches accompanying the motion. 

The pleasure surrounding her penis was too much, and Celestia was having trouble holding on. She desperately wanted to feel Luna's anus clench around her cock as they came simultaneously, so she looked around the room for something to stimulate her sister beyond compare. Her eyes fell on one of the logs that was resting on the carpet below her. Lighting her horn, she lifted the log up, and positioned it right outside Luna's wet cunt. She pulled out her dick, and let her sister force a glob of crap out before dipping the log in the new mess, and pushing it into her pussy as she stuffed her cock back into her ass.

The navy alicorn let out a loud moan, surely letting the entire castle hear her pleasure, as both Celestia's cock and poop pushed in and out of both her holes. With her own, wet scat coating the log of shit, it slid in and out easily. 

Knowing Luna would not last long like this at all, and not knowing how long she would be able to hold out, Celestia grinned devilishly as she slightly adjusted the angle of the log to an all-too-familiar angle, grinding it directly against Luna's G-Spot. 

Luna screamed as she suddenly came, her anus clenching down around her sister's cock. Celestia too, grunted, as her balls quivered and her seed rushed up her cock. Moaning, she unleashed a load of hot, sticky cum into the dark alicorn's already full rectum. Luna somehow still found it in herself to squirt some more, gushes of her juice spraying up onto Celestia's chest and groin, and soaking into the log of shit still wedged deep into her vagina. 

The two lay there for a moment, Celestia's cock still deep inside her sister's ass, and Luna was on the bed, panting as she rode out the end of her third orgasm of the night. Even though she had only cum once, Celestia was still very pleased with how the night had turned out.

Luna looked up at her sister, looking at the chunks of liquid shit that clung to her white face and ethereal mane. "That... that was amazing," she gasped. Celestia could only nod in agreement.

Slowly, the white alicorn pulled her cock from Luna's butt, watching in satisfaction as a mixture of cum and runny shit leaked out with a wet fart. She leaned down, and gently licked at the abused hole, letting her cum and Luna's crap flow into her mouth. The anus flexed, and a wet, messy fart exploded in Celestia's face, coating it with even more liquid shit and gooey cum. She grinned at the feeling of her muzzle being covered in her sister's mud, and continued to taste the rancid bitterness directly from the hole it came from.

Luna let out a soft moan of her own as Celestia softly tended to her pucker, and weakly pushed to make sure that her sister got her fair share of muddy crap. 

Celestia gathered a bunch of Luna's runny poop in her mouth, and trailed upwards, taking a generous bit out of the log still poking out of her sister's pussy. Then, she climbed up on the bed, and over Luna, leaning down to kiss her sister full on the lips. 

They both moaned as Celestia opened her mouth to let its dirty contents spill out into Luna's as well. Their tongues wrestled though the mud and cum as they passionately kissed, before they parted after a few long moments. Both swallowed what they head left in their mouths before breathing heavily.

"Celly," Luna said softly. "Let me suck your dick..."

The alabaster alicorn chuckled at the request. "Seems like you can't get enough shit today, Lulu," she said as she positioned her body to oblige. 

Celestia's groin was absolutely coated with Luna's mucky filth, shit coating her entire dick and pelvis. Chunks of it stuck to her large balls, and Luna leaned in to those first. She ran her tongue along the outside of each, white orb, lacking the large chunks of her own poop off before popping each on into her mouth to suck on gently. Finally moving to the main course, she licked up the length of her sisters rod, and then slipped the tip inside her maw.

Celestia moaned as her sister cleaned her penis, and leaned back. In this position, she found her head close to Luna's messy rear. Leaning in, she took yet another bite of the log in Luna's cunt, getting a taste of her own flavor. She chewed quickly, moaning as the bitter flavor of crap filled her mouth once again. It wasn't long before she took another bite, and another, and soon the two sisters were sixty-nining each other. Celestia ate her own crap out of Luna's pussy while Luna cleaned her runny shit off of the pearly white cock.

Luna let out a final moan around Celestia's dick as she weakly came once again, this time only dribbling marecum over her sister's muzzle as they both cleaned the last of their mess off each other's genitals. 

"Well, Celly," she panted. "Was that better than fucking each other in the throne room?"

Celestia weakly grinned. "Maybe," she replied.

"We'll just have to test out both and see for ourselves..."
