Giving the Marshmallow a Chocolate Filling
What am I doing with my life?
Dear Rarity,
It would be my pleasure to have you here in Canterlot this weekend, especially for ‘a very private matter’, as you put it. I do hope you can bring yourself to tell me what you want; it seemed quite clear that, from your letter, you are quite nervous about your request. Nonetheless, I look forward to your arrival. See you soon,
Celestia.
*** *** ***
Rarity, especially after the long train ride to Canterlot, was incredibly anxious; her planned meeting with Princess Celestia wasn’t exactly for... ‘friendship lessons’. Or maybe it was. What she planned to ask the princess for may indeed prove to be a very intimate lesson.
As the white unicorn slowly cantered through the streets of the posh city, dread slowly filled her heart at what she was about to do. She felt like the eyes of all the surrounding ponies were on her, accusing her of being a sick, dirty ruffian who deserved nothing less than to be shunned from ponykind forevermore. Still, despite sweating profusely from the stress of her nerves, she soldiered on to the big, intimidating castle that was illuminated by the orange of the sunset.
It was probably only a few minutes rather than the hours it felt like before Rarity had arrived at the castle gates. A pair of white stallions adorned in golden armor stood watch at the entrance, and one stepped in front of her as she walked up to the gates.
“What is your business here?” he questioned gruffly. “There are no court sessions scheduled on weekends.”
“I... I have requested a personal audience with the princess,” she explained slowly, her voice wavering. “She’s expecting a pony named Rarity, and well... I am Rarity.”
The two guards immediately opened the gates to let her in, not looking for any type of identification whatsoever. Rarity gulped, and slowly began her approach to Princess Celestia’s private chambers where she’d been instructed to meet her.
After no less than two encounters with other Royal Guards and a very sleepy Luna, Rarity found herself standing outside the doors that led to where the princess herself was, without a doubt, waiting.
Gulping again, Rarity raised a hoof to knock on the door, but a distinct voice interrupted her action.
“Come in, Rarity.”
By now, the unicorn was visibly shaking with nerves, having no idea what the consequences of what she was about to do would be. Celestia may banish her, ashamed that she had kept such a pony in her kingdom. Oh, what would her family think? Her friends? They would never talk to her again, never visit her in her new country, never think of her as a friend again, but as a monster.
“Are you going to come in?” a voice piped up. “Or are you going to just stand there until I have to come out for dinner?”
“Oh!” Rarity snapped out of her thoughts, pushed through the double doors, and was greeted with the sight of Princess Celestia lying comfortably on her large, circular bed. “Hello, Princess,” Rarity said formally, bowing low to the ruler. “Sorry to have kept you waiting.”
“Please, Rarity,” Celestia protested softly. “We are meeting as friends, not ruler and subject. If I may ask, please don’t be so detached by acting like the latter.”
“Sorry Pr- Celestia,” Rarity broke her bow, and walked up to the edge of the bed where Celestia hadn’t shifted.
“Yes, my little pony, you may join me here,” Celestia smiled. “There is plenty of room, after all.”
Rarity flushed, impure thoughts flooding her mind as she hoisted herself onto the soft mattress. She sat herself down on the floral-patterned duvet in front of the curled up alicorn.
“So Rarity,” Celestia started. “I got from your letter that you wish to make a request under less than public conditions, am I right?”
Rarity shuddered, the thought of what she would soon be saying making her heart pound in her throat. “Y-yes, that... would be right,” the unicorn stammered. Celestia raised an eyebrow at the way Rarity was acting. “I um...” Rarity pawed at the duvet. “I was kind of wondering...”
“Yes?”
“Well, you see...”
“Yes?”
“I kind of um.”
“Yes?”
“I want to...”
“Yes?”
“Kind of uh...”
“Yes?”
“I want to eat your shit!” Rarity finally wailed, before hiding her face behind her forelegs in shame and bursting into tears.
Celestia was dumbstruck. Of all the things she possibly could’ve expected, that was right at the bottom of the list. She wasn’t even sure if she heard right. I want to eat your shit! No, Rarity couldn’t have said that. The princess stared at the bawling pony in front of her. “Uh... come again?”
“I’m so sorry please don’t banish me I have a sister to look after and all my friends would miss me and I don’t not want to see them again and-” Celestia stopped Rarity’s panicked rant by reaching a hoof over and placing it over the unicorn’s lips.
“It’s okay Rarity, really. Now, just repeat what you said slowly,” Celestia cooed. “I promise I won’t banish you or anything silly like that. Where would you even get such an idea?”
Rarity sniffled and looked up at Celestia’s comforting face. “No,” Rarity sighed, tears still in her eyes. “I’m sorry, I should’ve never have come here.”
Rarity started to get up, but a hoof on her shoulder dragged her down again. “It’s okay, we all have some strange desires,” Celestia smiled. “Believe me, I’ve seen and done worse than... what I think you asked for.”
“Princess!” Rarity exclaimed, shocked at the words that had come out of the seemingly demure alicorn.
“What?” Celestia acted surprised at Rarity’s bafflement. “I have existed for thousands of years, Rarity. Of course I have tried many things over the years...” Celestia winked at Rarity. “Coprophilia included.”
Rarity gasped again, absolutely astonished at what her princess had just admitted. “What are you saying, Princess?”
“I’m saying that if you meant what you said before, I’ll be happy to go through with it.”
Rarity was amazed. Was it true? Had Celestia just agreed to let her finally realize her dream?
“... Really?”
“Yes, it’ll be my pleasure,” Celestia smiled. “In every sense of the word.”
“Oh thank you, Celestia!” Rarity leapt up and wrapped her hooves around Celestia’s neck, nuzzling her affectionately for a moment before realizing that it was the princess she’d just gone and molested. She pushed off Celestia, sending herself tumbling off the bed and landing heavily on the floor.
“Oh Rarity!” Celestia laughed. “You do realize we’re about to get a lot more intimate than that very soon!”
Rarity weakly nodded, dazed from her less than graceful landing. She heard Celestia climbing off her bed, the clopping of her hooves coming toward where she lay on the floor. Rarity felt a pressure on her shoulder, and suddenly she was on her back. Celestia’s face was upside down, looking at her with an expression of amusement.
Rarity grinned uneasily back at her, heart once again pounding rapidly in her chest.
Celestia’s amusement gave way to concern though, as she asked “Are you absolutely sure you want to go through with this?”
Rarity nodded yes.
“Okay, we’re going to establish safe words, okay?”
“Yes, Celestia.”
“First safe word, for when your limits are being pushed, is daisy. Essentially yellow. What is the first safe word?”
“Yellow.”
“Good,” Celestia chirped. “Second safe word, for immediate termination of activities, is rose. What is the second safe word?”
“Rose.” This was really happening. Rarity was still having trouble believing it, but it was becoming easier to believe as Celestia walked over Rarity so that her rear was above Rarity’s head.
“Ready?” Celestia checked one last time.
“Yes, I’m ready, Celestia. And thank you for this, so much.”
“Then we’re a go.” Celestia began lowering her royal posterior down to Rarity’s waiting muzzle, the alicorn’s pucker lining up with Rarity’s lips perfectly. Soon, her lips met the asshole of Celestia’s behind, and Rarity sucked and stuck her tongue into the hole in some sort of kiss. Celestia sighed at the sensations Rarity’s tongue was giving her, but that’s not what they were here for. With a grunt, Celestia began to push.
Rarity felt Celestia’s buttocks flex, before the hole around the unicorn’s tongue widened and a soft, wet, almost mushed-up-grasslike but still pasty substance forced its way into her mouth. To Rarity, it didn’t really have much taste at all, save for the slight tang of fermented vegetables. The unicorn chewed Celestia’s excrement fervently, swallowing it as fast as she could before more feces came out of the alicorn.
Rarity couldn’t eat as fast as she was being supplied, and shit began oozing out from around her lips, bits falling down and landing on her neck, staining her pristine white coat with the distinct brown of Celestia’s crap. Yes, this was what Rarity wanted; Celestia on top of her, making her messy with her waste.
Celestia stopped for a moment, giving Rarity a few moments to catch up, brown fluid leaking out of the unicorn’s mouth as she squeezed the moisture out of the shit while compressing it to a swallowable size. The alicorn turned her head to watch as, seemingly in ecstasy, Rarity chewed up her feces. Celestia saw the bits that had fallen to the ground and on Rarity’s chest, and, with a mischievous grin, turned around and used a forehoof to start rubbing the bits of excrement into Rarity’s coat.
Rarity moaned into her mouthful at the sudden contact from the princess, watching with delight as her fur was dyed a new colour, and she spat out some of her mouthful so Celestia had more to rub in. Soon, Rarity’s whole chest had been coated in a fine layer of the stinking solids. By now, the smell was almost unbearable and that made Rarity all the more happy as Celestia continued to deface her body.
Once there was no more shit to spread, Celestia shoved her hoof into Rarity’s mouth, and ordered roughly, “Clean.” Rarity nodded as fresh shit-smell breached her nostrils once more and slid her tongue around Celestia’s brown-stained hoof, doing her best to remove the layer of feces surrounding it. Rarity’s tongue pushed into the bottom of the hoof, scraping away the mush that clogged it up, and she savored the taste before swallowing it down into her stomach with the rest of what Celestia had supplied.
It wasn’t long before Celestia’s hoof was nigh-spotless, save for the slight brown stain left over and the layer of spit now covering the hoof. Celestia pulled her foreleg up again, and walked around Rarity so that the princess was standing at the end of Rarity’s hind legs.
“You ready for this?” Celestia said teasingly as she walked forwards, straddling Rarity as she pushed out her presents as she walked. First, bits landed between Rarity’s legs, maybe scraping the insides, then it hit her cunt, sliding against her clit as more piled on top of it. Then the shit-fall was hitting her stomach, chest, and finally her face was shitted on. Great, big lumps of feces hit her on her nose, chin, cheeks, and she closed her eyes tight as the princess’ droppings landed on her forehead, getting through her mane and coating her horn.
Celestia, having covered Rarity in her shit, massaged the crud into Rarity’s horn, bits getting stuck in the leylines.
“Oh Celestia!” Rarity cried out. “Oh yes, keep that up!”
Small sparks were shooting from the unicorn’s horn, and using her other hoof, Celestia stroked Rarity’s mane, spreading stripes of brown through the purple coiffeur. Celestia started using her magic to stimulate Rarity’s horn, freeing up her first hoof to wipe more of the alicorn’s shit into Rarity’s face.
“Oh yes, Celestia!” Rarity cried out; her being covered in the princess’ shit had made her so horny, and the stimulation from her horn was enough to cause her to climax, her juices mixing in with the feces that had landed in and around her crotch.
Celestia smiled. “I take it you’ve enjoyed yourself so far?”
Rarity sighed blissfully. “Oh, most definitely...” And she had. Celestia’s droppings had, in some way or another, covered her entire front. The stench was atrocious, and Rarity loved that.
Celestia waved a shit-stained hoof in the air. “Ready for round two?” she asked, winking at the unicorn.
The layer of crap on Rarity’s face wrinkled a little as she smiled eagerly. “Oh please Celestia, I would love that!”
“As you desire,” Celestia grinned. The alicorn scooped up a big dollop of her own crap off of Rarity’s belly, and went over to Rarity’s moist cunt. Her smile widening, Celestia tried to plunge the entire scoop into Rarity’s snatch. However, due to the shit being too soft, only some actually made it in before Celestia’s hoof ran into Rarity’s folds.
Still, it was enough for Rarity to cry out again as Celestia continued to rub the feces into her love-hole. The alicorn rounded up the shit that had gone in all directions with her first attempt at filling Rarity up, and with precision, pushed the crap inside. This proved to be very effective, and Rarity moaned deeply as she was filled up.
Celestia continued to collect shit to shove up Rarity’s twat, and with each thrust of Celestia’s hoof, Rarity could feel herself being filled up. It wasn’t long before Rarity could feel pressure against her cervix; Celestia had to hold a hoof against her entrance to stop the feces from spilling out. While keeping Rarity’s hole sealed, Celestia started making circular motions, helping Rarity relax.
“Mmm... oh yes...” Rarity moaned, the combination of the shit and Celestia’s hoof rubbing her button was already making her own juices flow. “Celestia...”
“Mmyes, Rarity?”
“I think...” the unicorn started. “I think you need to give it to me, now.”
Celestia nodded, and readied her hoof, before forcefully plunging it deep into the mare, the shit being compressed inside Rarity’s hole before squeezing past her cervix and into her womb. “Ah! Oh my!” Rarity yelled in pain at the sudden torment of Celestia’s hoof burying itself deep within the unicorn. Rarity gritted her teeth at the sudden, uncomfortable feelings wracking her body.
“Are you alright?” Celestia asked, concerned that she’d been too rough.
“No, please, continue,” Rarity begged.
“As you wish, Rarity.” Celestia slowly pulled her hoof out, the action causing a shlurping noise as Celestia gently started to push in and out of Rarity’s vagoo. Each slow thrust caused the unicorn to elicit a grunt as the princess’ hoof pushed more and more shit through her womb’s tight entrance. “How are you faring?”
“I’m... fine...” Rarity panted. “Your hoof, though... it’s very... big.”
“Indeed it is,” Celestia agreed, who kept up the pace. “I can sense you’re getting close. How about one last bite before I finish you off?”
Rarity chose to reply to this by opening her mouth wide. Celestia chuckled, and picked up one of the few lumps of shit that hadn’t gotten squished into Oblivion™. The floating poo made its way over to Rarity’s waiting maw, hovering teasingly out of reach.
“Celestia, please let me eat the nugget,” Rarity whined. “Why are you denying me my bliss?”
Her plea and question were completely ignored by the princess, so Rarity tried to lift her head up to get at it, but the little shit stayed tauntingly out of reach. Celestia chuckled to herself before upping her assault against Rarity’s muff.
“Oh!” Rarity cried out as the hoof that was embedded within her pushed in and out harder, faster, better and stronger than before. Rarity could feel a different kind of pressure to the one caused by the feces in her womb filling her loins; she knew she was going to climax. “Celestia, please! Shove it in my face right now!”
Celestia, also knowing that Rarity was close to orgasm, complied, ramming the shit right into her mouth. It was too big, though, and some of it went up her nose. The combined pleasure from Celestia’s work, the shit coating her vaginal walls and womb, the feeling of being full of shit in her stomach and finally the taste and smell of the new excrement that was on her face and in her mouth threw her into the throes of what had to have been one of the best, most intense orgasms of her life. Her screams of ecstasy could be heard echoing throughout the halls of the castle.
Celestia removed her hoof from the dazed mare, and slowly stepped away, realizing that the unicorn wasn’t going anywhere. The alicorn frowned. After all she’d done to Rarity just then, and she didn’t even get off! Well, at least Rarity owed her now.
The taste of shit was in Rarity’s mouth. The smell of shit was stuck in her nostrils. The heavy feel of the shit in her stomach. The still-pleasurable feel of the shit inside her vagina. The... she didn’t really know what the shit in her womb felt like... nonetheless, these all combined to make one very warm, fuzzy feeling spreading throughout her body. One very soothing, blissful feeling... so nice that she could just... drift away...
Celestia regarded the unicorn with a look of bemusement as she watched the smaller pony fall asleep right there on the floor. She sighed, stretched, and went to clean up.
*** *** ***
“Hurry!” Celestia cried, hosing down Rarity in the bathroom that connected to the defecated bedroom. “I don’t want my sister to catch wind of this! I’d never hear the end of it!”
“What about me?” Rarity moaned, scrubbing herself down with a bar of soap held in her magic. “My career would be ruined!”
“Let’s just get ourselves and my room cleaned up before some servant blunders in here.”
“Yes, Celestia.”
“Princess Celestia.”

Fun fact 1: I Google Imaged actual horse shit so I could describe it better.
Fun fact 2: I thought I could get away with writing this without getting a whyboner. I was wrong.
