Anon Gets Transformed Into Futa Celestia's Diaper As She Goes About Her Work Day Foodscatting and Jizzing Into You

The Chapter Where Anon Gets Transformed Into Futa Luna's Diaper As She Goes About Her Work Night Foodscatting and Jizzing Into You

A day of being a living diaper, helpless to resist the will of your tormentor, has made you even more of a fatalist than you already were. And so, even though you have your human body back for the moment, you don't thrash or struggle as Celestia's magic levitates you alongside her.

The trip to Luna's bedchamber would be fairly long on foot; the two sisters occupy separate towers within Canterlot Castle. But the architecture features wide balconies in each tower, permitting Celestia to fly from one to the other quickly. You float beside her as she crosses the gap, trusting her magic to keep you safe as you pass through the dizzying heights. She lands on the balcony of Luna's tower, passes saluting guards, and walks through marble halls until she reaches the door to Luna's bedroom.

"Sister!" calls Celestia, knocking with her hoof on the ornate door. "I have a wonderful surprise for you this evening."

"Give me a moment," comes Luna's muffled voice. "If your surprise can wait until after the moon is raised, I would be ever grateful."

"My sister," says Celestia, smiling at you. "She is not a morning person." She pauses thoughtfully. "Nor the nocturnal equivalent of one." She turns back to the door and raises her voice. "Anon has come to visit us!" she says.

To your surprise, that seems to motivate Luna. You hear hasty hoofsteps on the opposite side of the door, and soon it opens, revealing the moon princess running a brush through the starlit void of her mane. "Anon," she says, dipping her head in your direction. Turning to Celestia, she says, "Has he been bad, sister?"

Celestia smirked. "He's been quite bad, Luna. Ever since he arrived in Equestria. But I think I've devised a way of getting through to him."

The magic that's holding you aloft glows brighter, and you experience the now-familiar feeling of becoming a diaper. Your body compresses and becomes soft - it's almost comforting, in a way, like being swaddled in warm cloth. Your body rotates, and your "eyes" are turned towards Luna. "Sister!" says Luna, her face lighting up with surprise and amusement, "I never thought you'd actually do it! I take it you've had some time with him?"

"All day," says Celestia. "We had great fun, and Anon learned a little something about himself. He loves being a big diaper full of delicious princess poop and thick royal cum. But you know how he is, Luna... he's so terribly contrary, I think he's going to try and convince himself he doesn't like it."

"Ah, I see," says Luna. "We need to immerse him in the experience. Fill him again and again until he cannot deny to himself that he loves to be a diaper. We will make him beg for it, sister dear."

"Oh, I would never be so cruel as to make him beg," says Celestia. With her magic, she moves you closer to Luna, and the moon princess picks you up with her blue aura.

"I would," says Luna. She levitates you to her backside and wraps you around her butt. The warmth of her furred skin is comforting; it feels right, somehow, to be wrapped around a pony's ass. Maybe that's due to a mind-affecting power of the transformation spell - or maybe you're just a pervert. One thing's for sure: Moonbutt is superior to Sunbutt. Bigger and thicker, just the way you like it.

"Well, I'll leave you two alone," says Celestia, yawning. "Be sure to create a mental link with Anon. It wouldn't have been half as fun if I couldn't listen to him complaining." You hear her walk down the hallway, and Luna turns away from the door, shutting it behind her.

"Sir Anon?" says Luna. "Please say something if you can hear me."

"Yeah," you say, though the link between your minds. "I'm here."

"I must apologize for my sister," says Luna. "She's being terribly unkind to you."

"Oh, thank fuck," you say, "I'm so glad you're not on board with this diaper shit."

"Pardon?" says Luna. "Oh, no, do not misunderstand me. I am very much 'on board.' I wish to apologize for my sister's equivocation. Her intention is not truly to teach you a lesson about yourself - or at least, that is not primarily her goal. She desires you, Sir Anon. You have captured her heart."

"Seriously?" you say. "Why?"

"You do not return her missives, Sir Anon. You insult her to her face, in front of her subjects. To a monarch so powerful and so loved, disrespect is a rare and heady spice. She wishes to have you... and to degrade and humiliate you as well."

"God damn it, I am not a tsundere!" You yell. "I'm just an asshole! Earth women understood that."

"Or perhaps we see something that they do not," says Luna.

"No, I mean it!" you say. "I think... I was never very good at making other people happy. And I started to base my whole personality around making other people angry, which made me easy prey for-"

"For fuck's sake, Anon," mutters Luna, "I did not inquire after thy life's narrative." You feel movement inside you - Luna's fat blue cock, formerly sheathed, is beginning to emerge. Like her sister, she's packing an enormous horse dong. "In any case, Sir Anon, I confess your disrespect tickles a corner of my heart as well... and the thought of filling you with my shit and my cum is terribly exciting." She strolls toward the east-facing window, pointing her ass - and you - in the opposite direction. "Now then, shall we raise the moon? I hope you are hungry for chocolate... and cream..."

Luna's back legs bend, and you feel her cheeks spread. Her asshole opens wide inside you, and the head of a thick turd touches your soft interior. You taste it right away - it's rich chocolate, with the same thick texture as Celestia's poop. Brownies. The first turd, thick as your wrist, slides out of her and settles inside you, bulging your diaper-body. At the same time, her cock creeps further and further out of her sheath, and you taste the musky flesh and the first salty drop of pre.

The brownies are incredible, maybe the best you've ever tasted. And you find that you don't mind the taste of her cock, either - there's something mouthwatering about the musky flavor of her arousal. You recall the surprisingly tasty mingling of Celestia's shit and cum, and you find yourself curious to see how Luna's salty cum and chocolate poop will taste together.

Oh fuck, you think to yourself. No, no no, I am not enjoying this! God, is it really this easy to start accepting that you're someone else's diaper?

"Oh my," says Luna, squeezing out another thick chocolate turd, "I'm sensing some conflicted emotions from you, Sir Anon." Her hips start to gyrate, and the flared head of her cock rubs rhythmically against your interior. "You have a princess' cock inside you, growing hard and close to cumming. You have the taste of her delicious chocolate shit on your tongue. You have every reason to be happy, sir Anon, and no reason to despair."

"Back on earth, no one ever tried to shit in me and tell me I should be grateful."

"I am sure your world has... mmmhh... many taboos around defecation," says Luna. Her second turd breaks off inside you, and a rumbling chocolate fart fills your senses. "But my poop is a sweet gift, Sir Anon. You must learn to accept kindness, no matter what form it takes." Her hips move faster, and her cock twitches inside you, spurting thin jets of precum into you.

"Including cum?"

"Most certainly including cum, my little human," says Luna, her body shuddering. "You must learn to love my cum as much as you love my shit... you must beg for my cum, you must worship my regal cock and my glorious asshole... hahh... You will be grateful and reverent, you shall be the royal diaper forever and ever, I shall fill you, and fill you, and fucking fill you with fat chocolate logs and thick salty cum-"

Her whole body jerks forward, and her dick shoots a splatter of cum into you. The thick fluid flows down, settling into the bottom of your diaper-body along with the coiled brownie logs. As you expected - and dreaded - the two tastes are surprisingly good together. Another jet of jizz hits you, then another, and the rest of her climax dribbles languidly into you as her body steps backwards on wobbly legs.

"Sir Anon..." she says, "You will be pleased to know... the moon is... raised."

"Yeah, awesome," you say. "You managed to do the thing you do every day. And which your sister managed to do while you were in jail for being a bitch."

"Oh yes," moaned Luna, "that's the fire I like to see." She backs herself into her bed and softly pushes her diaper against it, squishing her chocolate shit inside you. "Back before Equestria was tamed - before it was Equestria - my sister and encountered such spirited resistance in our quest to unite the nations of ponies. So many stallions we brought to heel, dominating them with our cocks and filling their mouths with fat logs of sugary shit. And when you curse me, dear human, I am reminded of how wonderful it feels to conquer a stallion with my poop."

"Go fuck yourself."

"Yes, yes, resist," Luna groans. "Making you beg to be my diaper will be all the sweeter."

"Ugh, fine then," you say. "How about this? Shit in me. Or don't. I don't care."

"Well, I am sorry to disappoint," says Luna, "But I have entirely emptied myself for the moment. Worry not - shortly after my morning repast my bowels will be mightily full and ready to feed you another load of chocolate logs."

Luna points her butt at her breakfast, and you give it a look. It's pretty similar to Celestia's - pancakes, toast, pastries - you get the sense that Luna has slightly different taste in fruit than her sister, but you're not all that interested. It's all going to be chocolate shit by the time it gets to you.

She does seem to love her coffee, though. A large carafe sits on the table as she takes her seat - squishing her poop inside you as she does so - and over the course of the meal she drinks all of it. "Ah, another fine brew," she says, after her first sip. "You know, a thousand years ago, coffee was difficult to come by. Of course we had no trouble getting our hooves on it, but the average pony would never taste it. And now it's everywhere."

"And after I drink this much coffee," she says, "I have to take the biggest dumps." You feel her ass clench and release inside you, and a long chocolate fart stirs your insides. "Ah, the prelude," she says. "Worry not, I shall share my breakfast shortly. You are light now, but I will make you heavy with my fat, fudgy turds."

"Time for the day's work to begin," says Luna, straightening her legs.

"We're just back in your bedroom," you say. "What is it you do again?"

"I tend to the realm of dreams, Sir Anon," says Luna. "And this night you shall accompany me." She spreads her wings and flaps them once, creating a sound that seems to shake the world - and then her bedroom falls away like a curtain, revealing a starry void. For a moment, you're stunned - but then Luna releases a crackling series of chocolate farts into you.

"Ooh," says Luna, "Your next meal is on its way, Sir Anon. I don't usually eat quite so much, but I want to fill you so big... to test the limits of your cute diaper body."

"Wait, so we're dreaming now?" you ask, looking over the swirling void. "We're both dreaming?"

Luna chuckles. "Ah, inquisitiveness - one of your few unsullied virtues, Sir Anon. I was trying to tease you, and your desire to understand was stronger than your indignation."

"Uh, thanks?"

"We are not asleep - rather, we are physically presentin the realm of dreams, Sir Anon. From here, we may visit the dreams of any pony who is sleeping. I tend to the dreamers, ensuring that their dreams are enriching and their sleep is restorative."

"Okay," you say, "So where are we going?"

"Where we are needed," says Luna.

"We?"

"I was employing the royal 'we,' Sir Anon. Many ponies require the aid of an alicorn princess. Very few, I should think, require the assistance of a living diaper filled with chocolate turds." She raises her head, and the tip of her horn glows blue. "It seems there are no emergencies at the moment, so we may tour the dreaming world at our leisure. I think one destination in particular would be especially fun..."

She abruptly breaks into a gallop, making your heavy diaper body bounce up and down on her ass. As she charges forward, one of the twinkling stars ahead of you begins to expand; you can see colors and shapes begin to form inside it, and it quickly becomes an image. And that image extends into three dimensions, becoming a space that Luna trots into.

You're in a circular room with wooden walls, wooden floors, wooden bookshelves - the whole thing seems to be carved out of a tree. You don't recognize the room, but you do see a familiar face - Twilight Sparkle, Princess of Friendship, is slumped on a pink couch. She's staring down at her crotch, where a foot-long horsecock protrudes, and she's using her magic to rub the flared tip.

"Ugh, I keep forgetting Twilight has a cock," you say.

"Your memory must be quite poor, then," says Luna. "Her stallionhood is by no means small."

"No," you say, "She usually uses a spell to hide it while I'm around."

"Ah, then she will be very pleased to hear how much you enjoy being full of cum," says Luna.

You let out a low, grumbling sigh. "So where are we?" you ask.

"You would not recognize it," says Luna. "It is Ponyville's library, destroyed and replaced before your arrival. Twilight has many memories here, and it lives on in her dreams." She trots over to Twilight, who doesn't react to her presence. "She will not see or hear us until I permit it," says Luna. "It seems she is pleasuring herself... shall we give her something to pleasure herself to?"

She points her butt - and therefore you - at Twilight, and Twilight finally notices you. But she doesn't seem surprised; instead, she looks at you as if you've been there the whole time. "Hey, Anon," she says, "You're looking really handsome today."

You start to say something - but before you can speak, you hear your own voice speaking words that aren't your own. "Thanks," it says. "You look good too. You've got a really cool dick."

"A really cool dick?" That's not how you talk. "Hey, Luna," you say, "Are you making me say stuff in her dream?"

"No, her subconscious is still in control," says Luna. "While she hides her penis from you in the waking world, it seems that she longs for you to accept it." Luna might not be controlling the dream, but she's clearly enjoying it; her cock is stiffening inside you, distending your crinkly body as it grows.

"Thanks, Anon," says Twilight. "I'm glad you like my dick. So how do you like being on Princess Luna's butt?"

"It's so good," says your voice. "I love getting filled with her big chocolate turds. She took a big dump in me already, and I hope she poops in me again soon..."

"Ooh, I'd like to see that," says Twilight. "You look so big and squishy and full of chocolate poop... Can I rub my dick all over you?"

"Of course you can, Twilight," says your voice. "I want to feel your big purple cock squishing around my poopy diaper body." Luna, only too happy to play along, lowers her butt onto Twilight's lap. Her stiff cock sinks into your mushy backside, and she begins to thrust her hips, humping your diaper body.

"You're so soft..." breathes Twilight. "So full of poop..." As she humps your backside, you feel Luna's body moving inside you: her guts are shifting, her cheeks are spreading... she's pushing out the first turd of her next big load of chocolate shit. And Luna is moving her hips back and forth, rubbing her cock against the hot, lumpy mass of brownies she's already dropped in you.

As a helpless diaper, heavy with shit, you're pinned between two princesses and their perverse lust. You can feel their thick horsecocks sliding against your body - Twilight outside of you, Luna inside - and Luna is pushing another hot fudgey dump into you. The first chocolate log is almost as long and fat as her cock, and you feel your body slump lower as its weight settles into you. Luna grunts, pushing two more heavy logs into you, seemingly in a hurry to make you as big and heavy as possible.

"Oh, Anon," Twilight groans, "You're so big and squishy and poopy... you're so warm on my cock... I wanna fuck your messy diaper body and blow my load all over you..."

"Cover me in your hot cum," says your voice. "I want to be a big poopy diaper for you... I want to be fat and heavy which chocolate shit..."

It's pretty upsetting that Twilight's dream is speaking on your behalf. But it's even more upsetting that the things it's saying in your voice are kind of true. And on top of that... hearing yourself say them makes them all the more convincing. As a diaper, it feels good when a pony uses you - and the heavier you get, the better it feels. And Twilight's cock is squishing around the chocolate mess inside you, turning that pleasure into rising tension. As a living, magical diaper, you're somehow capable of orgasm... and you can feel it approaching.

But Luna beats you to it. Her cock jerks, and a gush of thick, salty alicorn cum splatters against your insides, mingling with the enormous load of chocolate poop you already contain. You're unsettlingly accustomed to the taste of pony spunk now; you're really starting to appreciate the way it complements the rich, sweet taste of Luna's poop.

"I'm gonna cum," hisses Twilight. "Anon, I'm gonna cum all over you... you big, sexy, shit-filled diaper..."

Her cock twitches as it starts to pump her load... And you climax at the same time, waves of pleasure shooting through your crinkly diaper body.

And then, without warning, your perspective shifts. You're disoriented, your vision mostly obscured... but you can feel a weight bearing down on you, squishing around the thick brownie mess inside your bloated body. Twilight's moans are coming from above you now, and the cock inside you shoots a spurt of cum that tastes subtly different...

Twilight is wearing you now, you realize. The as far as you can tell, no one cast a spell; this is just dream-logic shit. Twilight is wearing you, cumming in you... and now you start to feel another familiar sensation: her cheeks are spreading as her asshole opens up. "Anon!" Twilight gasps, "I'm gonna shit... I'm gonna fill you with my poop..."

Twilight pushes a fat log of foodscat into you, bloating you with even more mess. The feeling of being filled gives your orgasm a second wind, and your voice shouts out, "Yes, poop in me, Twilight! I want to be full of your yummy shit!"

You're honestly not sure whether you really said that, or if it was the dream voice that's been speaking for you.

Twilight's shit is firmer than either of the royal sisters'. It takes you a moment to realize that she's shitting entire candy bars into you - long, king-size bars of chocolate that break into pieces as they hit the material of your diaper body, exposing the flavors within. There's caramel in there, and a dry cookie with what might be hazelnut flavor. It's exquisite, like some kind of high-end, artisinal Twix. And it goes wonderfully with Twilight's thick, salty cum. The first one is gigantic, almost a foot long, and the next few descend gradually in size.

Twilight sighs happily as her cock shoots its last little spurt and her butthole drops one final fun-size bar into you. You're huge now, enormously bloated with desserts delivered straight from Luna and Twilight's royal assholes. Twilight wiggles her hips inside you, squishing and spreading the mess underneath her.

"Anon," she says, "I can't believe I came so hard... and pooped so much... I... I think I'm in love with you, Anon."

Before you can react, the room vanishes, and you're back in the starry void of the dream world with Luna. "Best not to overstay our welcome," says Luna - who, you now realize, is wearing you again. "If you wish to have a heart-to-heart with Princess Twilight, you may do it in the real world. For now, I think it is safe to say we have successfully 'incepted' a desire to use you as a diaper."

The dream world fades, and you find yourself in Luna's bedroom again. "I shall return you to your human form, Anon," she says, magically gripping the tabs of your diaper body. "It seems you have quite literally had your fill - and it is difficult to move with your shit-filled body dangling down to my knees. Princess Twilight's addition to it is quite heavy..."

"Wait," you say, as Luna levitates you off her body and tapes you up, "Twilight's shit is still inside me? Even though we were in a dream when it happened? Does that mean you-"

That line of thought is interrupted by a much more important realization. "Wait a minute!" you shout. "I recognize those candy bars! Twilight's always offering them to me when I come over... and oh fuck, she always watches me eat them with that intense expression on her face! And... and that one time I told her I was really craving one of those candy bars, and she started breathing really heavy and sweating... God damn it!"

Luna bursts into laughter - and her telekinesis falters, dropping your squishy, shit-filled body to the floor with a splortch.

Anon Gets Transformed Into Futa Celestia's Diaper As She Goes About Her Work Day Foodscatting and Jizzing Into You

In Which Anon, Having Been Freed From The Direct Attentions of the Royal Sisters, Is Nonetheless Transformed, Jizzed, and Foodscatted Into By Another Pony, Namely Rarity

You lay tangled in your sheets, frowning at the morning sun that peeks through the curtains of your spacious guest bedroom. Before sunrise, Luna had turned you from a diaper back into a human, then teleported you to a guest room - specifically, to a spot three feet above the bed. And you’d expected to sleep the whole day, but you’re slowly coming to realize that you aren’t sleepy.

“Motherfucker…” you groan, covering your eyes. “Not sleepy, not hungry…”

Despite the fact that you’ve been awake for about twenty-four hours straight, you’re completely alert. Being a living diaper apparently means that you’re not subject to the normal cycles of a human body… and being filled with Luna’s brownie shit or Celestia’s blondie dumps, not to mention big loads of their horse cum, apparently takes care of your nutritional needs. And if that power came from anything besides a diaper transformation spell, that would be pretty cool. But now you know that the princesses can keep you as a diaper. Twenty-four hours a day, never needing food or sleep, trading you off from day to night.

And what was worse, you’d probably learn to like it. It probably wouldn’t even take that long.

The door to your room swings inward, and you groan again, turning away from the door. It’s Celestia, you’re guessing; the sun’s already up, so she spared you the sun-raising dump… but she’s still got plenty of brown-sugar shit to fill you up with after she turns you back into a diaper. “No…” you whine, shutting your eyes tight. “Gimme a day off.”

“A day off from what, darling?” asks a voice that doesn’t belong to either Luna or Celestia.

Rarity is one of the ponies you’ve gotten well-acquainted with, as a resident of Ponyville. Like most ponies, she’s almost unfailingly kind. She’s a little prim, but you’re kind of an asshole - so if it’s anyone’s fault you’re not better friends, it’s definitely yours.

“Nothing,” you grumble. “The princesses were giving me shit all day yesterday, and I need a break from it.”

“Oh, poor little you,” says Rarity. You feel the bed bounce; Rarity’s hopped up onto the mattress with you. “I imagine you got your fill of blondies and brownies, didn’t you, dear?”

“I mean, they were good,” you say, your eyes still shut tight. “But yeah, getting filled up like that is-”

“Wait a minute," you say. “Did they tell you-” You sit up, opening your eyes - and you find yourself staring right into the tight purple butthole of Rarity. Before you can react, her pucker opens up and blasts you with a long, loud fart. Smells like raspberry cheesecake.

“They told me all about the fun you got up to, yes,” said Rarity. “And they taught me a neat little spell that I simply can’t wait to try out!”

“What? Aw, fuck-” But there’s nothing you can do to stop it. You feel yourself shrinking, your limbs crinkling into plastic tabs as the spell transforms you. In seconds, you’re back to being a pony diaper, lying on the guest bed. Rarity wastes no time, levitating you onto her plump white bottom and fastening you to her body.

“Come on,” you say - in the voiceless way that you “speak” when you’re a diaper. “Is every pony going to wear me on their ass and fill me with shit?”

“Well, I don’t know about every pony,” says Rarity. “But Celestia owed me a bit of a favor, after I designed the dress she wore at last year’s gala.” She steps down from the bed, daintily placing her hooves on the marble tile. “Well, to be honest,” she continues, “the chance to design a dress for a princess - one who so rarely wears anything - was a tremendous honor, not to mention a boost to my business. She’s one of the few ponies I’d permit to pay me in ‘exposure,’ but she was gracious enough to pay me a handsome fee and provide me with this opportunity to-”

“Yeah, great, great,” you say. “I guess I shouldn’t be surprised that Sunbutt is already thinking of every angle to humiliate me from.”

“You know,” says Rarity, “It’s not polite to interrupt a lady when she’s speaking. Your attitude might account for why so many mares want to turn you into a diaper and poop in you. I have only ever been kind to you, Anon, and you just say the most hurtful things. I believe you can be better, but you need to be taught a lesson.”

“Right,” you say. “So three ponies in a row think the best way to teach me a lesson is to turn me into a diaper? I think it’s a lot more likely that you just have a shit fetish, you filthy fucking horse.”

“You have such hang-ups around poop, Anon,” says Rarity. “Don’t you know that pony poop is a delight? Didn’t Celestia and Luna teach you that it’s a thing to be treasured? They told me that you loved the taste of their sweet turds.”

“I hate to break it to you,” you say, “But your princesses are liars. You should probably overthrow them.”

“Well, if you didn’t care for their poop, perhaps you’ll like mine,” says Rarity, trotting towards the guest room’s door. “Just because the princesses are regal, doesn’t mean they have the best-tasting dumps. Mine are a treat to the senses, Anon, and I can’t wait to share them with you.”

“Well, at least you won’t be filling me with horse cum…” you mumble.

“Oh, you don’t think so?” says Rarity. “I think it might surprise you just how many mares have big, long cocks… we hide them in public, but then the time comes to share them with someone very special…”

You feel something shift inside you. Horrifyingly, it’s become a familiar feeling: the sensation of a big horse dick filling your diaper body, rubbing up against the inside of you. And worse, it feels good; it’s unfair how good it feels to be touched when you’re a diaper.

“Dammit,” you mutter, “horse cocks everywhere I go…”

“Do you have the slightest idea how much self-control it took,” says Rarity, stepping through the guest room’s door and into the hallway, “Not to push you to the floor and shove my big purple cock in your mouth, every time you rudely dismissed the fashions I showed you? How tempted I was to pin you to the floor with my magic and bury you in my shit?”

“I used to think ponies were nice,” you say.

“Oh, we’re plenty nice,” says Rarity, “You’ve been a terrible nuisance, and I’m practically rewarding you. I’m about to give you your fill of delectable treats… not to mention my intimate affection. If you were a gentleman, you’d be happy to receive a lady’s thick, salty load.”

“Thanks for the etiquette tip,” you say. “So what’s the plan? Are we headed for your Canterlot location?”

“Oh, listen to you,” says Rarity. “I was all but certain you never listened when I talked, Anon! And yet you remembered that I opened a Canterlot Boutique here in Canterlot!” She strolls down the hallways of Canterlot Castle, swaying her bottom. “Yes, I do plan on heading back there, but… dear me, I am hopelessly lost in this castle. Who knows where the two of us will end up?”

You’d roll your eyes, if you had any. You can still see, but your vision is pointed backwards, so all you see is a swaying view of the castle’s halls as you look out from Rarity’s backside. You’re not that familiar with the castle’s layout, but as Rarity makes her way through its twists and turns, you begin to get the impression that she isn’t taking the most direct route to the exit. In fact, you seem to be making your way towards a very different part of the castle. Crossing a threshold, passing a pair of guards, you immediately notice there are far fewer ancient tapestries and far more lockers and trophy cases.

This must be the magic academy Twilight attended in her youth. Ever since coming to Equestria, you’ve always insisted that magic was fake, purely because it flustered Twilight when you resolutely denied the obvious. But you have to admit that magic, when it’s not turning you into a fucking diaper, is pretty amazing. You wouldn’t have minded visiting the magic academy, under very, very different circumstances.

“Yes, I am entirely turned around,” says Rarity, stopping by a tall door made from dark wood. “If we are to have any hope of finding the exit, I’m afraid I’ll have to ask for directions.”

Something about her tone sounded practiced; whatever was happening, you got the impression that it was planned. And when Rarity opens the door and you hear voices - dozens of voices - from the room within, you begin to think you won’t like what she has planned.

“Oh dear!’ says Rarity. “I was just looking for the exit. I hope I’m not interrupting anything?”

“Well, we are in the middle of a class,” says a voice you recognize as Princess Celestia’s. “But I always have time for a friend. Class, this is Rarity, a friend of Twilight Sparkle.” Voices murmur in acknowledgment, but you can’t see their source; you can’t see anything unless Rarity points her ass at it.

“Ah, nice to meet you all,” says Rarity. She enters the room, shutting the door behind her, but you still can’t see the class. “Sorry for interrupting… what class is this, exactly?”

“It’s a graduate-level transformation course,” says Celestia. “We were just discussing methods of converting living creatures into objects with magical properties. And if I’m not mistaken, you might have something to show the class, Rarity.”

“Why, you’re quite right,” says Rarity. “You shared a spell with me just this morning, and I’ve only just started to enjoy it. Perhaps we could share it with your students?”

The students murmur again, and Celestia must have nodded - because Rarity turns her butt towards the class and clears her throat. You can finally see the class; the students are fully-grown ponies, graduate students, all watching attentively from auditorium seating. Looking at you - although at the moment they probably don’t see you as anything more than a thick diaper that Rarity happens to be wearing.

“Students,” begins Rarity, “perhaps you’ve heard of Anon, the human? A creature from another world, a bit of a minor celebrity despite his somewhat grating personality. Well, it so happens that despite his strange origins, magic affects him just the same way as it affects us. This lovely thick diaper I’m wearing is, in fact, Anon himself! Thanks to a spell that Princess Celestia shared with me, I was able to transform him into this attractive and functional garment.” She turns her hips, showing you off from all angles.

“That’s right,” says Celestia. “Now, there are a number of things to keep in mind when performing transformation spells on a sapient creature. Firstly, such spells require a great deal more magical power than transformations of inanimate objects. Secondly, the creature’s form or nature will typically find a way to express itself in the appearance of the transformed object. You can see here on the side of the diaper…” Celestia points at you with her hoof, “this diaper bears the symbol of a question mark inside a green circle, which someone familiar with Anon would immediately recognize. Were this transformation performed on a pony, the diaper would almost certainly bear their cutie mark instead.”

“And most importantly,” says Celestia, “Consent is paramount. You are transforming a living, thinking person, potentially depriving them of the ability to move or speak. It is an unthinkable break of magical ethics to do that unless you have explicit permission from your subject, and that is something I hope you will all bear in mind when you are paired off for practice.”

“Hang on,” you say. “What’s this consent talk all of a sudden?”

“Yes, yes,” says Rarity - addressing the class, and very much ignoring you. “I am by no means a magical scholar, dearies, but consent is indeed a crucial component of this sort of spellcasting. I would never have used this spell on Anon if he had not begged me to turn him into a diaper and wear him on my rump. He so admires my bottom, the naughty boy… he wanted so much to be wrapped around it, I really couldn’t say no.”

“Yes, just yesterday he shared that fantasy with me as well,” said Celestia. “He worships the asses of mares, that human. I wore him for a day, and shared him with my sister Luna last night. Of course, transformation is good for far more than just fulfilling the sexual fetishes of humans, but once you become comfortable with these spells, perhaps Anon will beg some of you to wear him as a diaper! He’s becoming something of a slut in that regard.”

“So, is embarrassing me just your highest priority?” you ask, pretty sure that Celestia can’t hear you. “Like, in life? Is this just what you’re devoting every minute of every day from now on?”

“It’s also good practice to create a mental link with your subject,” says Celestia, “when their new form is unable to speak. You should all be familiar with that spell - but in case any of you need a refresher, the sigils are in your spellbooks. Rarity, is Anon telling you anything right now?”

“Hmm, hmm, give me a moment to listen,” says Rarity, cocking her head to the side theatrically.

“Look, I already know how this works, okay?” you say. “I call you a bitch, because you’re being a bitch, and you tell them I said I love being a diaper. I went through all this with Celestia.”

“Oh, he’s saying he’d just love it if I unloaded a big load of poop in him, in front of all of you! Dear me, I normally wouldn’t, but Anon is such an exhibitionist! I don’t think I’ll ever hear the end of it, if I don’t give him what he wants.” She bends her back legs, putting pressure on her bowels, ready to push out the first log of shit into you. “Tell me, class, would you like to see that? I’m sure Anon would be happy to have an appreciative audience.”

The class cheers and hoots and stomps its hooves. What is with this world? You guess you can see why creatures that poop edible food - really good food, in the cases you’ve seen - would have a different attitude towards poop. But these ponies are all excited to see a pony shit her diaper, as if it’s some kind of show. They’re not, like, totally losing their minds over it, but they seem genuinely stoked.

“You hear that, Anon?” says Rarity, wiggling her rump. “They want to see me dump some nice big logs into you, darling. I think you’re going to enjoy this quite a bit…” She grunts with effort, and you feel her cheeks spread inside you. The first turd pushes its way through her asshole and touches the material of your interior. It’s the same flavor you recognize from when she farted in your face: raspberry cheesecake, absolutely delicious if perhaps a little more dense and solid than you’d expect cheesecake to be. The first turd, maybe three feet long, curls against your inner surface - and after a quick cheesecake-scented fart, it's followed up by another one of equal length.

You feel yourself start to sag, and the students stare wide-eyed as you start to bulge with the size and shape of Rarity’s dump. “Oh, he's a bit heavy already,” says Rarity. “Should I pace myself, darlings, or do you want to see me keep on pooping?”

Predictably, the students call for more, and Rarity delivers. Her asshole opens up again, releasing a thick cheesecake turd at a glacial pace, and Rarity moans with pleasure as she fills you. Her cock is growing, unsheathing itself and thickening inside you.

You feel a hoof depressing your surface, squishing the mess inside you, and Celestia - the hoof’s owner - comes into your field of vision. “One advantage of transmuted objects,” she says, “is their increased durability and improved function. Anon, for example, is capable of holding far more shit than an ordinary, non-magical diaper. I personally tested his capacity just yesterday, and not only did he hold up wonderfully to a day’s worth of royal dumps, he discovered his love of being a big poop-filled diaper.”

“You know, says Rarity, grunting softly as she squeezes out another thick turd, “I think Anon and I would both enjoy putting Anon’s capacity to the test. He’s not limitless, is he, Princess Celestia?”

“Oh, not at all,” says Celestia, who's still using one raised hood to play with your squishy diaper body. “It's quite possible to overload him, if you put your mind to it. I'd be more than happy to assist you in your experiment, though. I'll send word to the royal kitchens, and have them prepare you a big breakfast for you to turn into a huge dump.”

“That sounds divine,” says Rarity. Her cock is at its full extension, its tip tenting the front of your diaper body. “I suppose I'll take my leave, then. I hope your students found my demonstration informative and enlightening.”

“Oh, I'm certain they did,” laughs Celestia, and the students stomp their hooves again. “They're free to choose any form for their transmutation homework, but I have a feeling that they're going to spend the weekend happily pooping in one another.”

“Happy to be a source of inspiration,” says Rarity, and she trots to the door. You, now loaded with her delicious shit, bounce gently behind her, your contents shifting slightly with each hoofstep.

“I see you're just as dedicated to humiliating me as Celestia is,” you say, as Rarity walks back towards the castle proper.

“Anon, you're thinking about this all wrong,” says Rarity. “Didn't you see how excited those students were? Now that you're a diaper, you're an instant hit! Anon the human was rather abrasive and, dare I say, not particularly happy. Anon the diaper is popular, and… well, you could be quite happy like this if you'd let yourself be.”

“Do I seem happy?” you grumble.

“Well, yes and no,” says Rarity. “My mental link gives me insight into your mind, Anon, and so I see how you thrill when my asshole opens and delivers a nice big cheesecake turd. I can see how stimulated you become as the head of my cock brushes against your inner surface. Right now, as we speak, it's driving you wild to be heavy with my mess and bulging with the shape of my hard cock. I suppose you're going to try and deny that?”

You don't respond.

“Like it or not, being a diaper gives you pleasure and fulfillment, Anon,” says Rarity. “Even this ‘humiliation’ you grumble at is a source of pleasure. So you can go on being a grouch, or you can embrace what you love and be a proudly exhibitionist diaper, pleased to be filled with a mare’s delicious poop and salty cum. You are an exemplary diaper, and you should be eager to show off what big loads of shit and cum you can carry.”

“Although, on that note,” she says, “I have made it my mission to overload you today, and I intend to follow through on that. We are nearing the kitchens, Anon, where a feast awaits…”

In a smallish private room, adjacent to the kitchens, Rarity sits down in a plush chair by a circular table. Her warm mess squishes inside you as her butt settles into the seat, and her cock pushes against your inner surface as she adjusts her posture.

You can't really see anything at the moment, with your “eyes” pressed up against the seat, but you can hear servers enter the room, rolling carts and setting down plate after plate.

“Jesus,” you mutter, “just how big is this breakfast?”

“I don't normally stuff myself like this, Anon,” says Rarity, “but I need to prepare a big meal for you! I'm going to overload your crinkly diaper body with a colossal mess. All these pancakes, all this fresh fruit, these fine pastries… all of them are going to become long, thick cheesecake turds for you to enjoy.”

Rarity digs in, scarfing down food and gulping down tea and juice in a way that doesn't strike you as ladylike. Even less ladylike was the way she began to stroke her cock as she ate, projecting a magical aura onto her shaft and sliding it up and down.. “Geez, Rarity,” you say, “you get horny when you eat?”

“It's not just the eating, darling,” says Rarity. “It's the thought of the gigantic dump this delightful meal is going to become. I think you're going to enjoy this food even more than I do, once it's been converted into a load of poop.”

“In fact,” she says, “I should probably make room for more, if I'm going to give you the biggest load I possibly can…”

Her eating doesn't miss a beat, and neither does her self-pleasure, as she grunts and pushes another turd through her puffy purple asshole. Since she's sitting on you as she shits, her dump immediately gets squished under her weight, spreading out into the growing mass of raspberry cheesecake she's depositing inside you.

“Oh yes, more please,” she says - and after a moment,you realize that she's not simply mumbling to herself. She's ordering more food, on top of the dozens of plates that were set down at the start of the meal.

“How can you possibly eat this much?” you ask. “Even Celestia only had one course, and she's like twice your size.”

“The body of a pony is a marvel,” says Rarity, between bites. “Not only do we poop delectable treats and shoot big sticky loads of cum… our bodies can hold absolutely miraculous quantities of food, should the opportunity arise…” she dumps another cheesecake turd inside you, and her cock jumps. “Are you excited to taste my load, Anon? Are you thirsty for Rarity’s yummy sticky cum?”

The answer, unfortunately, is yes, as much as you try to suppress that emotion. Feeling a mare’s cock shoot inside you is a strangely fulfilling experience, and you shiver with anticipation of the warmth and flavor of Rarity’s seed. Her cock throbs once, twice, then shoots, spurting a thick stream of salty spunk. Her cum splatters off your inner surface, dripping down to her lumpy mess. As ever, the mingling tastes are surprisingly good together; the rich, musky cum and the dense raspberry cheesecake sit pleasingly in your “mouth,” and a fresh supply of both is still filling you up. Four thick turds and five thick pumps of cum bulge your body, leaving you almost twice as big as you were before Rarity started breakfast.
Rarity’s climax isn’t the end of her breakfast, though. She cleans her remaining plates, with one hoof massaging her softening cock through the front of her diaper. Once she’s finished, she thanks the kitchen staff and sets off for the castle’s front gate, trotting past the guards and into the Canterlot streets. “Oh, great,” you moan, “Now I’m a diaper in broad daylight.”

“I wouldn’t worry,” says Rarity. “It’s not as though ponies passing by are going to realize you’re Anon the human. And I’m certainly not going to go around shouting it. “

“Ah, right, because you’re the fancy snooty horse,” you say. “You only humiliate me in ways that fit your theming.”

Rarity snorts, and you can hear genteel annoyance in her voice when she replies. “If you’re accusing me of being one-dimensional, I would advise you to take a look at yourself, Anon. I’ve seen little evidence today that you know how to do anything but complain.”

“Complaining is what people do when you treat them like shit, Rarity.”

“Treating you like shit would require a different spell, Anon, but I’m sure I could convince Princess Celestia to provide it,” says Rarity. “In the meantime, perhaps I could lend you out to Pinkie Pie. She’d certainly bounce through town proclaiming that she was wearing you as a diaper.”

“Ugh, please no,” you say. “Everyone’s staring already.” Indeed, you draw long looks from ponies Rarity passes by. It’s a little hard to read some of their expressions, but they don’t seem to be disapproving; they’re not as excited to see a full diaper as Celestia’s students had been, but they seem… impressed?

“Like I told you, Anon, they don’t know it’s you,” says Rarity. “They’re just impressed by the size of my dump and the capacity of my diaper. They’re probably wondering where they can buy a diaper that holds so much shit.”

“Great,” you say. “Nice to be noticed.”

After a short stroll, Rarity arrives at the Canterlot location of Carousel Boutique. The store’s manager, Sassy Saddles, turns toward the door as Rarity enters, greeting Rarity warmly before returning to the customer she’s assisting. “Ah, the store’s doing wonderfully,” she says to you, circling a rack of dresses. “I know I left it in capable hooves, but it’s nice to have an excuse to visit Canterlot. I love my customers back in Ponyville, but it’s not exactly the place to meet any new faces, you know?”

“No, go on,” you say, “I’m really invested in your fucking dress business.”

Rarity sighs. “When you talk like that,” she says, “It makes me think you want me to retaliate by humiliating you. You constantly antagonize ponies, Anon, and I think that Celestia has given you exactly what you were asking for the whole time: the opportunity to be powerless, and degraded, and filled with shit and cum.”

“Cool theory, Pony Freud,” you mutter.

“Hm, I’m not hearing a denial,” says Rarity. “Well, in any case, I shall be showing you off to my customers, and I will take every opportunity to degrade you completely.” She strolls over to a customer - a slim and graceful-looking mare with a white coat and a pale pink mane. “Fleur!” she cries excitedly. “I can’t believe my luck, darling, I was so hoping I would run into you when I was in town.”

Fleur responds with a squeal of delight, and the two mares embrace briefly. “It’s a delight to see you too, Rarity!” Fleur says. “I’m here often enough, I was bound to see you eventually… oh, and I see you’re wearing a rather bold fashion accessory today!”

“Oh, this old thing?” says Rarity, shaking her rump. “I’m quite happy with the attention it draws… and the longer I wear it, the more flamboyant it becomes!”

“Yes, I can imagine,” says Fleur, circling Rarity and peering at your diaper body from behind. “You’ve already got a nice healthy load in there, and it’s still early in the day! I’m sure I couldn’t measure up to your output, Rarity, but you are making me want to try out the diaper look.” She prods at you with her hoof, squishing Rarity’s cheesecake mess. “It’d look wonderful if it were even bigger, but it looks like this one’s nearly at its limit.”

“Oh, you think so, do you?” says Rarity teasingly. “This diaper actually has a surprising capacity, as I’m more than happy to demonstrate…” She bends her forelegs, raising her butt, and grunts with effort. Her tummy rumbles, and her guts shift slightly, and her asscheeks part - and what comes out isn’t another thick cheesecake turd, but a deep, loud, and long fart.

Fleur’s eyes go wide in surprise, but a smile soon breaks on her face. She breathes in Rarity’s fart, smiling wider as the aroma of raspberry cheesecake fills her nostrils. “That’s lovely, Rarity,” says Fleur. “With a fragrance like that, I’m not surprised you enjoy showing off a full diaper.”

“Well, it wasn’t quite what I was intending,” says Rarity. “I may need to clear out some gas before I can take a nice big dump in my lovely diaper.” She raises her head, looking over the boutique’s floor. “Oh, everyone? Everyone?” she says, addressing the dozen or so patrons in the store. “I’m Rarity, the proprietor of this establishment, and you may have noticed the large and very attractive diaper I’m wearing.” There are sounds of acknowledgment from the ponies.

“I’m afraid we don’t sell this particular article, although I’d very much like to,” says Rarity. “This diaper is actually a transmuted creature; not a pony, but the ‘human’ known as Anon.” There’s another general mumble of acknowledgment. “Yes, yes,” Rarity continues, “we were all fascinated when he arrived in Equestria, but let’s be honest: the human form is rather bland, isn’t it? I think Anon is much more attractive - and useful - as a big shit-filled diaper.”

A wave of agreement goes through the store, and Rarity waggles her hips in the direction of her customers. “I’m going to push a fresh load of thick, warm poop into this handsome diaper,” she says, “But first I’ll need to release a storm of farts into it. They will be deafeningly loud, darlings, and the fragrance may give you a craving for sweets… and if I’m being perfectly frank, I also plan on stimulating my cock while I fart. As long as I’m filling Anon up, I may as well feed him a salty load of pony cum, don’t you think?”

Rarity envelops her cock in a sleeve of magic and begins to stroke it - and at the same time, she grunts softly and shifts her rump. The cock-stroking magic crinkles your body as it moves back and forth, and her ass widens as a fart bubbles its way towards her butthole. With a happy sigh and a long, luxurious stroke of her cock, Rarity releases another lengthy fart, drowning out all other sound with the volume of her emission.

“Well, as long as I’m here,” says Rarity, “I may as well work with a customer. May I help you, Fleur?” Before Fleur can respond, Rarity farts again, and her knees shudder as her magic stimulates her tip.

“I’d be happy to have your personal touch,” says Fleur. “I’m going to be visiting the Crystal Empire, and I want something that will fit the crystal aesthetic but also stand out.”

“Ah, I believe I can find you something,” says Rarity. “Follow me, darling.” Rarity leads the way to another part of the store, expelling a loud blast of raspberry cheesecake gas that stirs up the sticky-sweet mess inside you. With your “eyes” on the back of your body, you can see Fleur smile as the fart hits her.

“Ah, lovely,” says Fleur, making “eye contact” with you. “Anon the human, is it?” she says. “We’ve never been introduced, but it’s nice to meet you. You’re quite lucky to be Rarity’s diaper, Anon. The fragrance of her shit is divine, and being full of it is such a privilege. Not to mention how she’s stroking herself inside you, getting ready to shoot her load… How are you liking it?”

“I’m not a fan,” you say. “But you can’t hear me when I talk, so it doesn’t really matter what I say.”

“Oh, he can’t properly speak,” says Rarity. “That’s how he prefers it. He likes being a diaper, and diapers can’t talk, you know?” She farts again, and her gas splatters wetly against her shit and cum. “But I can pass along a message from him. “How do you like being my diaper, Anon?”

“It’s fucking-” You’re cut off by another gigantic fart, which goes on for a good twelve seconds. It starts strong, rattling your whole body, before petering out to a little wet rumble.

“Tell her I-” Rarity farts again, cutting you off, releasing a series of short, loud emissions. You sigh, just sagging heavily as you wait for Rarity to be finished.

“What was that, darling?” asks Rarity. “You’ll have to speak up, Anon!”

You defiantly stay quiet, but Rarity doesn’t seem put off by your silence. “He says he’s quite happy,” she says, “But he wishes he was heavier. He loves my farts, but what he really wants is more thick tasty logs of shit.” She leans forward toward a rack of blue dresses, the aura flickering on her horn. Her magic tugs weakly at the rack, unable to pull a dress from its hanger. “I’m sorry, I’m having a little trouble with the dress,” she says, “All my magic is at work in my diaper, stroking my hard, fat cock…”

“Let me take care of that for you,” says Fleur. Her horn flashes pink, and the magical cocksleeve inside you suddenly changes. The aura is thicker, sliding over Rarity’s shaft more rapidly, and it makes Rarity moan lustily as her body shivers. Fleur is the one stroking Rarity’s cock now, if you don’t miss your guess… and it’s giving you quite a bit of pleasure too. For some reason, your diaper body has a form of sexual sensitivity, and you feel yourself ramping up to a climax...

“Oh goodness, oh, oh goodness,” gasps Rarity. “You certainly know a thing or two about pleasuring a lady’s cock, Fleur de Lis. You’re going to make me shoot a very big load, right in my lovely big diaper…”

“Oh, I’m looking forward to that,” says Fleur. “And I imagine your diaper is looking forward to it just as much! Why don’t you give him a little treat while he’s waiting to taste your cum?”

“I think I will,” says Rarity. “I’ve exhausted my supply of gas, and I’m ready to give my diaper what he really wants…” She strains, and what comes out this time is a thick, solid turd. In fact, it’s thicker than the turds she pushed out earlier in the day; apparently her enormous meal resulted in bigger, longer logs of raspberry cheesecake. It’s not easy to say with any certainty, but the first turd has to be at least three feet long, snaking its way into your diaper body and making you sag nearly all the way to Rarity’s knees.

“Oh, that’s a nice big poop,” says Fleur, and her magical cocksleeve begins to vibrate slightly. “If I were your diaper, I’d be so happy to feel that weight and taste that flavor… why don’t you give your big sexy diaper a few more big heavy poops?”

“Of course, Fleur,” says Rarity. “The customer is… always right…” She bends her back legs and grunts, pushing another thick turd through her stretched asshole. “You’re going to love how it feels to be big and full of my shit…” she groans, working another three feet of poop through her bowels. “So big you sag to the ground… and overflow with poop…”

“And cum,” says Fleur. “Don’t forget about all the cum you’re going to shoot, Rarity. So much hot, sticky, salty cum, dripping all over your sweet dump…”

“Oh yes, oh yes, lots and lots of cum,” moans Rarity. “A big hot load, filling you up, dripping out of you as you overflow…” she gasps desperately as Fleur strokes her off, pushing shit out faster, pushing out the remainder of one three-foot turd and shooting another one into you. You’re now to heavy that your sagging body rests on the floor - although that’s partly because her back legs are bent low.

The feeling of being so heavy with shit has kicked your senses into overdrive. You’re close to climax now, and so is Rarity, biting her lip and whimpering as Fleur excitedly rubs her cock. “Anon, I’m going to cum,” she grunts, thrusting her hips forward inside you. “I’m going to fill you up and make you bigger and heavier with my cum and my poop…”

You hit your climax first, your crinkly body shuddering with ecstasy - and then Rarity shoots her load, erupting in rapid-fire bursts that drench her mushy mess with thick salty horse cum. The taste - particularly in your heightened state of sensitivity - is heavenly. For a blissful moment, you’re washed clean of cynicism and resentment, content - even joyful - to be a shit-filled diaper on the ass of a big-dicked mare. Being passed around between mares and filled with their delicious shit has been one of the best experiences of your entire life. Feeling a mare’s cock unsheathing itself, thickening inside you, and shooting pint after pint of hot cum… you don’t ever want to give it up. And as much as you grumble about it, in this moment you know that you would beg for it.

Rarity keeps shitting as she comes inside you, pushing out another foot or so of cheesecake poop each time her cock shoots. More of your weight settles on the floor; your underside, heavy with shit, flattens against the carpet as pounds and pounds of shit slide into you. When her orgasm ends and her cum slows to a dribble, she weakly pushes out the remainder of one last turd and unsteadily straightens her legs. You’re hanging down to her ankles now, achingly full of her shit. You don’t know what your limits are, as a diaper, but you feel like you’re getting close to them.

“Ah, marvelous,” sighs Rarity. She plucks several dresses from the rack, displaying them for Fleur. “Let’s get you in a dress, gorgeous.”

“So where are we going now?” you ask, your body dragging on the ground as Rarity strolls through the cobblestone streets.

“We’re just going for another stroll, Anon,” says Rarity. “I don’t know if we’ll end up anywhere in particular.”

“Well, that’s a lie,” you mutter. “You just felt like going for a stroll while you’re wearing about a hundred pounds of shit in your diaper?”

“And why not?” asks Rarity. “I had to work hard to fuel this great big dump, Anon. It was a laborious breakfast, filling myself up with so much food… subjecting my body to the task of turning it all into shit… why shouldn’t show it off?”

“I still don’t understand the Equestrian attitude towards poop,” you say. You’re trying to keep your voice steady, but it’s tricky; the cobblestones keep bumping against your dragging diaper body, shifting the mess inside you. Rarity’s cheesecake poop is bouncing on your “tongue,” teasing you with the rich, delicious flavor - and the jostling is turning you on again, triggering your sexual sensitivity. If this “casual stroll” goes on too long, it’s going to make you cum. “Why exactly are you proud to show off a giant shit-filled diaper?”

“Well, I’m not sure how to begin,” says Rarity. “You’ve tasked me with explaining a whole society’s worth of cultural norms. The question of what’s fashionable - what you choose to ‘show off’ is likewise a topic on which I have a lifetime’s worth of insight-”

“All right, all right, you don’t feel like explaining,” you mutter. “Coulda just said so.”

“Well, maybe I’d feel more talkative if you were a bit more open,” says Rarity. “Why don’t you tell me how you truly feel about being a big heavy diaper loaded with pounds and pounds of sweet, sugary, rich pony poop? Why don’t you describe your thirst for pony cum and your love of mare’s cocks? I can feel all these emotions through our link, Anon, but I’d like to hear them in your own words.”

“Are you feeling how pissed off I am?”

“A bit,” says Rarity, “But much more than that, I’m feeling what you describe as ‘humiliation’ - but which seems to me more like an illicit erotic thrill at having so many ponies’ eyes upon your bloated, shit-filled form. They see you, and they admire you… and they would love to possess you and fill you with poop and cum, just as I am…”

You stare out from Rarity’s swaying backside, meeting the gaze of the ponies who are staring at the big messy diaper. You’re getting more looks, and longer looks, than you got on the way to Carousel Boutique. And it’s hardly surprising that people are staring at a diaper so big it drags on the floor, but the looks you’re getting are admiring, enraptured looks - some ponies are even following you for a short time, reaching out their forehooves as if they want to much around the mess inside you. You kind of want them to - you’ve been building towards a climax for some time, and a little attention from another pony might just be enough to send you over the edge.

Rarity may be sensing your arousal, because she grunts softly and raises her rump, pushing out an ear-splitting fart that shakes the lumpy, squishy mess inside you for a good fifteen seconds. With her gas cleared out, Rarity’s asshole stretches around another thick turd, pumping it into you a foot at a time. Rarity doesn’t miss a step; she’s still strolling briskly along the city streets as she dumps a fresh, warm turd into your body. You start to feel slightly different as the thick log coils inside you; you feel not just heavy, but full, as if you’re reaching your capacity. If you were still in your human body, this is where you’d declare you couldn’t eat another bite… but Rarity’s asshole is feeding you, bloating you, whether you want it or not. She pumps another three-foot cheesecake turd into you, and you stretch further, becoming achingly full. “Rarity,” you gasp, “I think I’m full… you gotta stop pooping…”

“Anon, dear, I already told you I intend to make you overflow,” says Rarity. Sighing with relief, she pushes another poop into you, making more of your bloated body drag on the cobblestones. It’s a little painful to be stretched like this, but it also feels good; your sensitivity is at its absolute maximum, driving your arousal skyward, towards orgasm…

And then Rarity stops. She stops walking, she stops pooping… and your arousal falls back downward, denying you your climax. “We’re here!” says Rarity.

“Here?” you ask. You can’t see what’s in front of Rarity, of course. “I thought we weren’t going anywhere.”

“Oh, well it slipped my mind just a bit,” says Rarity, “but it’s Canterlot’s famous Fashion Week, and I am just moments away from my scheduled appearance! I’ll be modeling my own fashions, as well as something really special…”

“So this was your plan all along,” you say.

“But of course!” says Rarity. “When I said I planned to overflow you with shit, you didn’t think I was going to do it alone, in a bare, drab room, did you?”

“No, I should have guessed you’d do it in front of a bunch of high-society ponies.”

“Not to mention lots of fashion reporters with lots and lots of cameras,” Rarity says, and you groan ruefully.

“Rarity!” cries a feminine voice, and Rarity body jostles as she and the other mare embrace. You’re in a room with rows and rows of dresses, presumably somewhere backstage at a fashion show venue.

“Coco!” says Rarity, stepping back from the hug. “How are things, darling? I’ve heard horror stories about Fashion Week, but you look like you’re holding up quite well.”

“I’m surviving,” laughs Coco. “I suppose my time with Suri prepared me for stressful situations and sleepless nights… at least now I’m making my own decisions! How about you, though? Sassy Saddles sent along a dress for you to model, and I was wondering why it exposed so much backside…. But now that I’m seeing you, I think I can guess why!” You feel a hoof pressing into the side of your body… and now that you’re achingly full of Rarity’s shit, even a gentle touch is agonizingly stimulating. You moan helplessly, unheard by the pony who’s tormenting you. “This diaper is amazing,” says Coco. “I’ve never seen one that could hold so much poop!”

“It really is a remarkable diaper,” says Rarity. “I know I can’t say enough good things about it, and I love hearing other ponies say nice things about it too…” She pauses, and lowers her voice to a devious whisper. “By the way, Coco darling, are you going to be doing the announcing while I’m on the catwalk?”

“Yes,” sighs Coco. “Yet another one of the duties that has me stretched thin…”

“Well, if it’s not too much trouble,” says Rarity, “There’s a few things I’d like you to say…”

“I don’t suppose there’s anything I could say to change your mind,” you say. You and Rarity are backstage, listening to muffled announcements in Coco’s voice and the snapping of flashbulbs. Rarity’s wearing a black dress that shimmers with color like an oil slick - and notably absent from that dress is any fabric covering Rarity’s butt. You’re completely exposed - and in a moment, you’re going to be exposed to what sounds like hundreds of ponies.

“You’re more than welcome to try,” says Rarity, “But I’m fulfilling my obligation to Fashion Week, promoting my business, and giving you comeuppance for being such a chore to deal with. Do you think you can say something that would convince me not to do all that?”

You think for a moment, and then sigh. “No, probably not.”

“Very reasonable of you,” says Rarity. “Oh, we’re on!”

Rarity strides forward with a confident gait, crossing the partition between the backstage and the catwalk. Flashbulbs are going off, capturing Rarity’s bold new look - and once she’s far enough along the catwalk that some ponies can see her gigantic diaper, every bulb is flashing as fast as it can. “You’re being immortalized,” says Rarity, and your magical link with her delivers her voice loud and clear over the murmur of the crowd. “You’re going to be the talk of the fashion world, Anon!”

“So cool,” you mutter. But you don’t really nail the sarcasm; being watched by so many admiring eyes is getting you horny again, and what you really want right now isn’t privacy, or freedom, or even to be human… you just want release.

Over the loudspeakers, you hear the voice of Coco - calm, but with enthusiasm befitting an announcer. “And here is Rarity, of Carousel Boutique, with a sleek black number of her own design. It would flatter any mare’s bottom… but it’s particularlystriking when one is wearing the other piece of her ensemble.”

Rarity reaches the end of the catwalk and strikes a pose, raising her rump and grunting with effort as she begins to push. If you’d had any doubts that Rarity was going to shit inside you in front of all these ponies, then…

No, never mind. You didn’t have the slightest doubt she was going to do it.

“The big, handsome diaper she’s wearing is unfortunately not available in any boutique,” says Coco. “Not only is it a magical diaper, ladies and gentlecolts, it is in fact a transformed creature!” The crowd murmurs with appreciation. “And not just any creature, but Anon, the human! A creature from another world, transformed into a diaper with remarkable capacity. Remarkable… but not limitless.”

Rarity’s asshole opens and pushes out another thick cheesecake log… and this time, it feels different. You had already felt agonizingly full… and it was more than just a feeling. You really are at your limit; as the long turd snakes its way into you, you feel it shifting the mess inside your body. And there’s nowhere for all that squishy mess to go… except out. Rich white cheesecake, ribboned with red raspberry syrup, begins to squish is way out of your leg holes and drop in clumps onto the catwalk.

“Look at that,” says Coco’s voice. “Even a magic diaper can overflow when you unload enough poop into it. Anon can taste all that delicious poop, and I have it on good authority that he loves it. And there’s something else he loves just as much. Rarity… why don’t you give it to him?”

Rarity begins to magically stroke herself, and she strikes a different pose - one that shows off the outline of her cock against the surface of your body. Cameras rise back up, all through the crowd, and flashbulbs fire off again. The sight of your transformed body, leaking poop as Rarity masturbates inside you, is forever captured by the fashion press. Your humiliation is absolute. Everyone sees you as you are: a massively bloated diaper, shit oozing out of your leg holes and over your waistband. You exist solely to hug a pony’s ass until you overflow with shit and cum… and it brings you such bliss to fulfill your purpose.

“There she goes,” says Coco, her voice dropping to a sultry whisper. “See how pleasure overwhelms her senses… everything falls away but the simple visceral joy of shitting… the soft, squishy, heavy warmth of her diaper… and the anticipation of shooting a sticky, creamy, salty load into that diaper.”

“How does it feel to be a fashion icon, Anon darling?” grunts Rarity, still pumping shit into you. Every pound of shit that lands inside you is another pound that overflows, creating a growing pile of mushy cheesecake around your sagging body. “With the exposure you’re getting, you could launch a lucrative and fulfilling modelling career… I could manage you, I could turn you into a diaper before every shoot… and hand you over to the loveliest mares in Equestria so that they can fill you with pounds and pounds of delicious poop in every flavor you can imagine… and then top it off with a big, hot load of cum!”

Rarity’s cock shoots inside you, her first erupting pumping several thick ounces of salty spunk into her collected mess. But there’s no more room for anything inside your body - not another turd, and not even another drop of cum. If something goes in, something has to come out - and so the shit that leaks out becomes noticeably streaked with glistening white cum, and the piled-up cheesecake shit around Rarity’s back hooves begins to drip with her spunk.

And you cum too. You feel like you’ve been waiting forever for this, but it’s so worth it; as a diaper, you have full-body climaxes of shocking intensity… and now that you’re swollen to your absolute limit, swollen until you overflow, it’s by far the best you’ve ever had. You and Rarity cum together: she moans in ecstacy, and you silently shudder as her shit and cum drips from your holes. And all the while, camera shutters are snapping and flashbulbs are firing. You’re not just a shit-filled, cum-splattered diaper; you’re the most famous diaper in Equestria.

Rarity’s orgasm ends, and she trots slowly back up the catwalk. Incredibly, she’s not done pooping - as she leaves the stage behind, she pushes out more long turds, overflowing your body while she walks. Every few inches, another clump of overflowing cheesecake shit falls from your leg holes or creeps over your waistband and plops to the floor.

“Ahh, thrilling as always!” says Rarity, once the two of you are backstage and out of sight. “If there’s one thing I know with absolute certainty, Anon, it’s that there is a place for everyone. I know that I belong in the world of fashion and high society. And as for you... “ She wiggles her rump, jostling your overfilled body - but all you can do is weakly moan. “I think you’ve found just where you belong.”

Anon Gets Transformed Into Futa Celestia's Diaper As She Goes About Her Work Day Foodscatting and Jizzing Into You

The Chapter Where Anon Gets Transformed Into Futa Celestia's Diaper As She Goes About Her Work Day Foodscatting and Jizzing Into You

"Anon," says Celestia, staring down at you with a grin, "So good of you to respond promptly to my summons."

"Summons?" you say, sitting upright. "I didn't get a summons, Twilight just fucking teleported me here from my bed."

"The details aren't important," says Celestia. "What matters is, I wanted you here, and here you are."

"What time is it?" you ask, squinting your eyes. You look out the window and see a starry sky. "Fuck me, who wakes up this early?"

Celestia chuckles softly. "Ponies with responsibilities," she says. "Like raising the sun."

"Oh," you say. "You wanted me to watch you raise the sun?"

"Sort of," she says. She begins to circle you, eyeing your body, nudging you here and there with her muzzle. You twist your body to try and avoid her, but you're cautious about putting up too much resistance - you've never bought Celestia's benevolence act. You're also a little leery of coming into contact with her big horse dick, which is creeping menacingly out of its sheath. You've come to accept that the ruler of Equestria is a princess with a big fat cock, but accepting it doesn't mean you want to touch it.

"Anon," she says, "Did you know that raising the sun is quite a strain... but also rather enjoyable?" You mumble noncommittally, and Celestia continues. "You see, Anon, I find myself wishing that I could... let loose when the feeling comes over me. And I'd like your help with that."

"What exactly are you asking me for, Sunbutt?"

Celestia giggles. "Oh Anon, you're so fond of that nickname. Some royals would be offended by such an appellation. Personally, I take it as a compliment that such a handsome creature as yourself has taken an interest in my rump." She bumps you with her rear, knocking you off balance with her considerable mass. "And I have an idea as to how you could get better acquainted with it."

"Woah," you say, backing away. "I may have given you the wrong idea..."

"Don't be shy, Anon," says Celestia, her voice becoming more seductive with each word, "Don't you know it's an honor to serve your Princess, even in the most humble of roles? And I have a role you're perfect for. Or at least... you will be..."

Her horn glows the color of sunlight, and her magic envelops you. You feel paralyzed, immobile, and your extremities grow numb... then seem to disappear entirely. You try to speak, but you can't move your mouth. You feel like you don't have a mouth, actually.

"Ah, you look wonderful, Anon," says Celestia. You're lying on the floor, totally immobile, and she's staring down at you again. "How do you feel?"

You try to speak, and Celestia gives you a quizzical look. "Oh," she says, "Let me establish a mental link, so that you can speak to me with your mind."

You focus your thoughts at Celestia, and mentally ask the horse bitch what the fuck she thinks she's doing.

"You can't tell?" she says. "I suppose it's an unfamiliar feeling. You, my little human, have become a diaper. A Princess-sized diaper with a little logo on the side... ah, I see. It's a question mark in a green circle, just as one might expect."

"You turned me into a diaper?" you say, though the mental link. "What kind of sick shit are you planning?"

"Oh, don't rush to judgment, Anon," says the Princess. "You might enjoy this experience more than you expect." Her magic envelops you, and you feel yourself being wrapped around her ample ass. The sensation of your soft diaper body being wrapped around her ass is actually enjoyable; the feeling of her half-hard cock pressing into your front is less enjoyable.

"You see, Anon," says Celestia, "Moving the sun puts a unique sort of strain on me. My body begins to yearn for release... in more ways than one. There's an indescribable buildup in both my royal bowels and my majestic cock. From time to time I indulge myself, but... oh Anon, regular diapers just don't do the trick! Only a magical diaper, created from a transformed creature, has the power to contain my loads."

"Then why me?" you ask.

Celestia sighed. "I have complicated feeling towards you, Anon. You don't respect me, and you're such a bother, but I can't stop thinking about you. I want to keep you close... but I also want to punish your unforgivable insolence..."

She begins to rub her hips against each other, making your body bunch up underneath her. Her cock grows, and the flared head pushes against your insides, dripping a bead of precum into you. To your surprise, you can taste it, all salty and musky.

"I can taste your cum..." you say, then a realization hits you. "Oh God, you're going to shit in me too!"

"Calm yourself, Anon. Have you ever observed a pony defecating?"

"No!" you say, "Why would I?"

"Well, if you had," says Celestia patiently, "You'd know that, unlike your species' foul excreta, ponies produce food. Fully edible, oftentimes delicious."

"You're shitting me."

"Not yet I'm not," she says. "But when I do, I think you'll be pleasantly surprised. Hmm, why don't I get started? My little ponies deserve a prompt sunrise, don't you think?"

You protest, but Celestia is undeterred. She parts her legs slightly, and her body tenses. She must be raising the sun; you can still see, somehow, but you're facing away from the window and you don't have a view of the eastern horizon. Her cock is growing inside you, drooling musky pre as it pokes further and further into your diaper body. There's movement in her backside, heralding the arrival of the sun princess' dump.

"Here it comes," says Celestia. "I'm going to... fill you with my poop!"

Her asscheeks part, and the head of a thick turd pokes against you, You can't help but taste it, and you're expecting it to be foul... but Celestia wasn't lying. It's sweet, and it has a thick texture you recognize...

"Are you pooping brownies?"

"Blondies, actually," said Celestia. "Similar to brownies, but made without chocolate. Brown sugar will be the dominant flavor, and... mmm... if you could chew, you'd notice toffee chips."

The turd pushes its way out of her ass and curls against your inner surface. Sure enough, your "taste buds" fill with sweet brown sugar. "You sure know your poop," you say, resigned to your fate.

"Of course I do, Anon. It's important to know what I'm sharing with my favorite human. And - ooh - if you want a princess to poop brownies into you, perhaps I can lend you to Luna sometime. I'm sure she would love a magical diaper to hold all of her shit and cum while she raises the moon..."

"What?" you shout, as the first footlong food-turd breaks off and settles inside you. "I'm not doing this again!"

"No?" says Celestia playfully. "I don't see how you have - ooh, ooh - much of a choice in the matter, my sweet little diaper. I can do this to you - mmff - whenever I want." She begins to push harder, and her thick, sweet shit pours into you, making your material crinkle and bulge.

You're about to voice another protest, but Celestia interrupts you thought process. "Oh, here it comes! Get ready for my sweet princess cum, Anon!"

The head of her marecock is already pressed against your insides, and when she spurts, her cum is thick as frosting, splattering forcefully against you. Spurt after furious spurt of jizz fills the front of you, and the taste of her sweet poop is joined by the musky, salty flavor of her cum. The volume of her orgasm is frankly scary; even if you were human, your body would still be bulging if she'd cum inside you.

Your body sags with the weight of Celestia's poop, and her cum pools thickly at the bottom as her orgasm dribbles out of her. "I'm sorry, Anon," she says, "I lied - my jizz isn't sweet. It's just horse cum." You don't feel like admitting it, but there is something nice about the way the salty and sweet flavors of her cum and shit mingle inside you. "So how does it feel?" she asks. "Now that you're fat and bulging with my royal seed and my sweet, tasty shit... do you love being a diaper on my big fat sun-butt?"

If you're being honest, it's not nearly as bad as you were expecting. But you're not about to admit that. "Whatever," you say. "Can you just turn me back to normal and let me get back to sleep?"

"You want to go back to sleep?" asks Celestia. "But your job isn't done, Anon. I've got a full day of cumming and shitting ahead of me, and so do you."

"What do you mean? I'm full!"

"Full?" she teases. "Not nearly. You're a magical diaper, my dear. You might feel full, but trust me, you've got a lot more growing to do."

"So you're just going to keep a diaper on all day?" you say, "Won't your subjects... notice?"

"I should hope so," says Celestia. You feel her legs moving, shifting around the sticky, sweet mess inside you, and she begins to move towards the door of her bedchamber. "My staff would be terribly unobservant if they failed to notice a messy diaper on their princess." She chuckles. "You assume there's something shameful about what I'm doing, Anon. But I've done it before, and no one tells a princess what to do with her royal mess."

Celestia's first stop is breakfast. Since your "eyes" are on the back of your diaper-body, she turns herself around so that you can see the spread on her dining table. It's a dismayingly large breakfast - pancakes piled high, racks of toast, a selection of pastries... everything an alicorn needs to start her day. "Mmm, I'm going to enjoy this," she says, "And then a little bit later... you're going to enjoy it." And then she farts, blowing brown-sugar-scented gas into you.

Celestia's assistants approach as she eats, presenting her with routine business. Between thoughtful bites, she gives her approval, or she doesn't. She arranges meetings or cancels them. And all the while, she farts loudly and proudly into you, eliciting no reaction from her staff. It seems they really are accustomed to seeing her in a messy diaper, relieving herself without shame.

"Mmm," she says, wiggling her butt in her seat, smushing her mess around inside you, "Nothing like a nice big breakfast... and in a few hours, a nice big lunch for my wonderful diaper."

Later in the morning, Celestia holds court. The throne room is lined up with normal citizens, all of whom are too polite, or too cowed, to mention the messy diaper that Celestia's ass is resting upon. With little else to do, you listen to the pleas of the ponies. Celestia listens too, and responds with sympathy and wisdom. As skeptical as you've been about Sunbutt's benevolence, she genuinely does seem to be a good ruler...

"Just a moment, my little ponies," she says, after hearing from a couple dozen citizens, "My breakfast has made its way through my system, and it's time to feed my poor neglected diaper a load of shit."

Never mind, you think to yourself. Sunbutt sucks.

"It may interest you all to know," she says casually, as a long fart signals the start of her dump, "That my diaper is actually a magically transformed creature. Would you like to know who I turned into a diaper?" Her dick starts to grow.

"What the fuck?" you yell, through the mental link. "Don't tell them!"

"I'm sure most of you know about 'Anonymous,'" she says, ignoring your objection. "Or 'Anon' for short. The grumpy little malcontent of a human. This morning, I turned him into a diaper, so that I could punish his disrespect and bad attitude by filling him with jizz and shit." She grunts, and a fat blondie log slides out of her ass, joining the lumpy mess inside you. "But to tell you the truth, my little ponies, I think he's actually enjoying it. I think he might beg me to keep him like this."

"She's lying!" you shout. "This is slander!" But no one other than Celestia can hear you.

"I think it's my poop that he loves so much," she says. "Maybe it would be a better punishment if I came inside him again. Maybe a load of my salty cum will show him the error of his ways."

There's movement around the shaft of her cock - you can't see it, but she must be using her magic to jerk herself off. "Oh," she moans, "My little ponies, I want you to watch me punish my insolent diaper with a thick load of pony princess cum." The motion around her cock becomes faster and faster, and she begins to move her hips inside you. Another thick log of brown-sugar turd presses into you, and a third follows right after it. Her cock pulses, and her cum shoots against your insides again, flooding your sense of taste with a fresh load of musky jizz. Once again, you actually find yourself appreciating the mingled taste of her sugary scat and her salty cum. But you can never, ever let her know that.

"Ahh," says Celestia, releasing a final lump of blondie-shit and a bassy fart into you. She wiggles her rump, squishing the enormous mess beneath her. Incredibly, your diaper body seems entirely capable of holding it all - there's no leaks, even as she smushes it around. "I think Anon is properly punished for now. Or rewarded, depending on how much he enjoys what I've done to him..."

With that done, she sees the rest of the citizens, none of whom seem especially put off by what they'd just seen. A couple of them, on their way out of the throne room, actually say goodbye to you, which is pretty humiliating.

"Well, my big messy diaper," says Celestia, standing from her throne. "I think it's time I had a nice... big... lunch."

Today's lunch, like breakfast, is a mostly private affair. It's also a gigantic meal that threatens - nay, promises - to become a massive load of dessert-shit in a few hours. Assistants come and go throughout the meal, bringing more business to the princess' attention. Your attention fades in and out - you find yourself focusing on the feeling of fullness inside your diaper body. Being so thoroughly overstuffed with Celestia's shit and cum actually feels good, like the feeling of having a satisfying meal in your belly. And since you still taste with your insides, the flavor of her sweet, lumpy shit and musky seed is perpetually in your "mouth."

You're forced to admit to yourself that being a diaper is actually nice. It's relaxing, Celestia's poop is delicious, and the humiliation... it's kind of a turn-on. If you didn't have your pride to think about, you actually would be okay with doing this again.

The time between lunch and dinner is fairly uneventful - just a few minor meetings, and a walk around the royal gardens. As Celestia takes her constitutional, your sagging diaper body swings underneath her. Your lumpy mass hangs almost down to her knees, and the motion of her hips inside you fills you with an nearly erotic sensation - but there seems to be no way for you to cum, so it builds and builds inside you, never finding release. Celestia teases you throughout the day, threatening to release another load into you - but each time, she just lets loose another big, sugary fart.

Finally dinner arrives - and it's an enormous, well-attended banquet in the castle's main dining hall. Of course it is. Celestia goes from table to table, greeting dignitaries and prominent citizens, introducing you as "Anon, the big messy diaper" and answering follow-up questions about your transformation and how much you love it when she cums and poops inside of you. You try to protest, but after several groups of ponies fail to hear you, you quiet down and let Celestia sow the seeds of your humiliation.

Finally, the princess takes her place at the head of the main table. As her body turns, you get a chance to scan the room. There's no one here you recognize, which isn't especially surprising - most of the ponies you know live back in Ponyville. If you're going to be publicly humiliated, at least it's in front of a crowd of strangers.

"Fillies and gentlecolts," begins Celestia, and then she launches into her prepared speech, praising the civic-mindedness and generosity of the ponies present. The banquet was about... education, maybe? Commerce? You sort of tune it out.

"And finally," she says, "We have a special guest with us. Some time ago, Equestria received a visitor named Anonymous, a "human" from beyond the known world. Many of you have heard of him... fewer, I suspect, have become acquainted with his persistently negative outlook and troublesome behavior. As a princess of this land, it falls to me to correct his behavior. As a disciplinary measure, I have transformed him into this big, handsome diaper you see strapped to my royal butt."

"I've spent the day filling him with my shit and cum, which has resulted in the sagging mess you see here. I'm not sure he's learned his lesson, though... I've come to suspect that he actually enjoys in when I poop in him and shoot my thick princess cum into his crinkly diaper body."

"But as long as he's still a diaper... why don't I try one more time to discipline him with my royal seed and my sweet, tasty turds?" The audience stomps its hooves and cheers, with what sounds like genuine enthusiasm. Celestia turns, so that your "eyes" are facing the audience and their eager smiles. God, why are they so into this?

Celestia grunts and lowers her butt, smushing the heavy mess inside you down into the floor. She grinds you into the floor, smearing the sugary, musky mess inside of you, and her dick grows out of her sheath, poking into your insides. She begins to jerk herself off magically, and the head of a turd pokes out of her asshole.

"Oh, he loves it!" Celestia calls out, her voice resounding through the banquet hall. "He loves it when I feed him my thick, sugary shit! Oh, he wants to be bigger! He wants to be full and fat and bulging with my poop!"

She jerks herself off faster, as thick logs pour out of her ass. Your own arousal is building too - you don't understand where it's coming from, since you don't have a human body, but you feel like you're somehow close to coming. Your diaper body bulges fatter and fatter as her mess grows, and you sag further and further down, still holding in every ounce of her brown sugar shit.

"Oh, I'm going to cum, fillies and gentlecolts!" cries Celestia, gasping for breath. "I'm going to soak this naughty diaper with my thick salty cum!" Crackling farts billow against your insides, and a single, thick turd presses against you, filling your senses with the brown-sugar flavor of her blondie poop. Then she cums, shooting thick ropes of jizz into you at a velocity that's almost painful. The presence of the crowd seems to be a turn-on for her, because she's coming harder than ever before, mingling an unthinkable volume of princess cum with the delicious poop that's already filling you up.

And somehow, you cum too, the climax shooting through your bulging, shit-filled body. You cry out through the mental link with Celestia, and she moans in orgasm right along with you, filling the hall with her outcry. Finally, she slumps to the ground, and your sagging body, filled with sticky mess, settles on the floor.

"So are we done here?" you ask, as Celestia closes the door to her bedchamber behind her. "Or are you going to shit out that big dinner into me before bed?"

"No," says Celestia, "That dump is for tomorrow morning. I'll turn you back to normal now."

She magically removes you and tapes you up, holding up your diaper body and the massive, lumpy mess within. You feel your body go numb for a moment, and then your limbs and your mouth are back - along with the rest of you.

But the feeling of fullness is still there. Your pat your bloated, naked belly and look accusingly at Celestia. "Is all that still in me?" you ask.

"You mean my shit and my cum, Anon?" says Celestia, looking at you with amusement. "Of course it's still inside you. Where else would it be?"

"Ugh, whatever," you say. The feeling of fullness, to your dismay, is still surprisingly pleasant - you'd prefer to remember this as an unpleasant experience, and it's hard to do that when so many parts of it are so enjoyable. "Just send me back home and please never do this again."

"You didn't enjoy being my diaper, Anon? Is that what you're saying?" You shoot her a dirty look, and she continues. "I don't think you're being honest with me. You see, our mental link shared more than just your conscious thoughts. I was able to sense the pleasure you felt as I filled you with my poop and my jizz. Even through all the shame, you loved being my big, fat, messy diaper."

You try to glare at Celestia, but you can feel the blood draining from your face. She knows. "You should be more honest with yourself about the things you enjoy, Anon. And if I'm going to teach you that lesson... I think you'll need to do this again.

You sigh. There's no arguing with a magical princess. "So... what, then? We're doing this again tomorrow?"

Celestia raises an eyebrow. "Why wait til tomorrow?" she says, as her horn begins to glow. "My sister should waking up soon, and I'm sure she would have just as much fun with you as I did..."
