Twilight has always loved asses. Big asses. Little asses. Plump asses. Firm asses. Watch what she does with the best ass in Equestria. Ever.

Twilight Sparkle has always been an ass mare. Whether they were big or small, plump or firm, squishy or muscled, she's always loved asses. Playing with them, kissing them, squeezing them, laying on them. But one ass in particular had eluded her. Until now. The absolute best ass in all of Equestria. Princess Celestia's plump pony ponut is just begging for some fun.

Small Disclaimer: I intended to make this an anal vore story but decided to just go with plain old Ass Worship.

The Only Chapter

Author's Note

This is intended to be the only chapter of this fic. It's plain out ass worship. I planned on making it an anal vore pony fic but decided that it would be more fun as it is. Lemme know what you think and I might expand on this particular fetish of Twilight's to include her friends.

The Only Chapter

Twilight had a secret. She liked butts. Big butts, little butts, firm butt, doughy butts. It didn’t matter to her, she simply liked butts. Her absolute favorite butt, however, was that of her mentor. Princess Celestia had the biggest butt in all of Equestria. She used to think that was a problem. She’d always loved butts, even when she was smaller. She’d take any opportunity she could to be close to a butt. Especially Celestia’s. As she grew older and started developing and gaining maturity, she decided it wasn’t a problem. It was simply a fetish.

A fetish she could have fun with. Upon moving to Ponyville and making all of her wonderful friends, she shared her fetish with them. Rarity was disgusted, but it was a strained disgust. Like she didn’t really feel that way, she was just putting on an act for the ponies around her. Fluttershy was surprised and hid behind her mane for the duration of the conversation, but she didn’t leave. In fact, every time the conversation drifted towards types of butts, her ears pricked up. Applejack remained silent, ever impossible to read. She was either intrigued or concerned. Rainbow Dash outwardly acted like she didn’t care, but the very moment Twilight mentioned she liked tight butts, Rainbow’s wings were straight and stiff. Pinkie Pie… Pinkie Pie immediately flew into questions about who’s butt Twilight liked the best.

Was it Rainbow’s? While Rainbow’s butt was pert and firm and Twilight would have loved to rest her head on that firm ass, no.

Was it Fluttershy’s? Fluttershy was far too skittish to make that sort of advancement on, but she did have a lovely butt.

Was it Rarity’s? Rarity has a perfect butt. Round and supple, and just the perfect amount of fat and firm. Not too plush but not to muscled.

Was it Applejack’s? Applejack had the sort of butt that any stallion would dream of. Firm and strong. A work horse’s ass.

Was it Pinkie Pie’s? Plush and squishy, Pinkie’s ass had been on her face more times than she cared to count and she’d found out first hoof that Pinkie’s ass tasted like marshmallows, but no.

The questions went on until Twilight grew somewhat tired of explaining why the butts she was asked about weren’t her favorites. She revealed it just slightly louder than intended.

“I love Celestia’s ass!” She shouted and the mares in the room went quiet. That silence was broken soon after by a thunk. Fluttershy had fainted.

Many ponies worshiped the ground Celestia walked on, like she was a Goddess made flesh. She had guards around her constantly. Ponies who would bend over backwards to clean her shoes. She even had ponies who personally saw to it that her throne was polished and shining. It was a near certainty she’d also had ponies confess that they loved her rear. Rarity broke the silence following Fluttershy’s faint.

“What about Celestia’s… posterior… do you love, Twilight?” she asked and Twilight stared at the table for a moment before sucking in a deep breath and letting out slowly.

“The size… the shape… the smell… the way it moves when she’s walking…”

“The smell?” Rarity asked, pausing for a moment.

“As her student, I did many an awkward thing. One such thing being walking muzzle first into her rear.” She said and Rarity nodded slowly, her face one of understanding. She’d done the same when she was younger, walking face first into her own mother’s rump when she was deeply engrossed in a fashion magazine. “I just don’t have the courage to tell her…”

“Maybe you should just show her.” Rainbow Dash said and all eyes turned to her. “I’m not super experienced in the love department, only having flings from time to time, but everything I’ve ever heard and seen has been about being up front with the pony you have feelings for.”

“But I don’t have feelings for her. I have feelings for her ass.”

“The pony’s part you have feelings for then. Just… I dunno, go up to her when she’s alone or something and kiss her straight on the ass.” Rainbow said and everypony around the table started voicing why that was a bad idea. She has guards. She’s a public figure. She’s never alone. She may be busy. All Twilight could think was… would it be that easy? Could it really be all she had to do was go up and just… kiss the ass?

Her mind started spinning, multiple scenarios coming to her head.

Scenario One)

“Hello Princess Celestia. I need to tell you something.”

“Go ahead Twilight. I am always happy to hear what you have to say.”

“I’m in love with your ass.”

“What? How crude. Get out, and do not come back.”

Scenario Two)

“Hello Princess. Can I tell you a secret?”

“Of course Twilight. I love a bit of gossip.”

“I love your ass.”

“My… ass? Well then, why don’t you get more acquainted with it.”

Scenario Three)

“Hello Celestia’s ass. How I do love you.”

“Twilight!? What are you doing back there?”

Every scenario Twilight thought up was either beneficial to her or very, very bad. Sucking in a breath, Twilight stood up.

“I’m going to talk to her.” She said before teleporting away. None of her friends were able to stop her. She’d done this particular teleport many times in the past, mostly to strengthen her own magical power. This time was for a more personal reason. Teleporting straight into Celestia’s bedroom, she stopped and looked around.

“Twilight? It’s always a pleasure to see you, but why are you here?” The voice of a goddess, as always. Twilight looked towards the bed and there she was. There it was. Celestia was fixing the sheets on her bed herself, stretched out over the large mattress. Her ass was the only thing hanging off of the bed and her tail was, for the first time ever in Twilight’s memory, tied up into a neat and tidy little bun.

“I… had a reason… and a plan… but I can’t remember now…” Twilight said and Celestia stared at her for a moment.

“Well, I will go back to finishing my bed and let you think about it. When you remember, simply call my name, and get my attention. I’ll be ready to listen.” Celestia said as she turned back to her task. She wasn’t using magic to fix her sheets. She was using her hooves. Her maids would be doing the same thing. Her ass stared at Twilight, as if encouraging her to simply act. Time seemed to slow down for her as she tried to gather her thoughts.

Many paths opened before her.

She could approach, tap Celestia on the flank and tell her how she felt. Perhaps the Princess would be understanding, maybe even giggle about it.

She could clear her throat, which may simply get Celestia to look over at her and she could tell her mentor’s ass how she felt while still feeling like she was telling Celestia herself how she felt about the monarch’s ass.

She could simply dive in, plant a few dozen kisses on that plump ponut and enjoy it until Celestia cast her out forever.

Swallowing hard, she decided on a course of action. Celestia’s ear pricked towards her as she walked forward. She didn’t say anything as she sat directly behind Celestia and gripped the Princess’s rear in her hooves. As if driven by some unknown force, Twilight leaned forward and kissed Celestia’s ponut directly in the center. “I love you.” She said and she heard Celestia giggle. That wasn’t a giggle of disgust or confusion. That was a giggle of understanding. And mischief.

It took exactly twenty seconds for Twilight to realize she’d triggered “Mischievous Celestia”. A side of her mentor Twilight only saw rarely when she was younger, Mischievous Celestia was far more fun. Princess Celestia was all about royal duties and keeping decent in the public eye. Mischievous Celestia used to go rolling in the mud with her student. Or dropping banana cream pies from the upper story windows onto the heads of nobility. Or pestering guards until they sneezed or chased them off.

Twilight realized she’d triggered that part of Celestia when she could no longer move. Her hooves were frozen and she couldn’t move much farther away from the glorious white ponut than an inch. “Oh? You love my ass do you? Well, perhaps you should get better acquainted.” She heard from her mentor before her muzzle was pressed firmly against the plump donut of white pony flesh. “Shall I tell you about my morning routines, dear one? Or would you like to find out yourself?” Celestia only ever called a pony dear one if she was teasing them. Or preparing to punish them.

Twilight tried to answer but her muzzle was stuffed against the plump pony princess ponut that just moving made the lips spread around her muzzle just slightly. Enough that her muzzle slipped in. She expected to be assaulted with the smells one typically associates with an ass. She was wrong. The inside of Celestia’s ass smelled like peaches. Freshly picked and then immediately cut peaches. She closed her eyes and immediately set to licking. She didn’t care how “gross” this was to some ponies. This ass was the ass of a goddess. Clean and pure, not a speck of filth anywhere.

Twilight enjoyed herself. Tasting, licking, kissing. Doing everything she possibly could to that perfect ponut. She didn’t much care if she never came out of it. She wanted to go farther in, get a better taste, but she didn’t dare. It might hurt her teacher and she didn’t want to hurt the ass. She wanted to love it.

The next day, Celestia was in court with many a noble. The usual silence was absent. Broken by constant sounds.

“Slurp. Slorp. Sllip. Smack.”

“Don’t mind that. What was it you wished to see me about?” Celestia asked, a blush adorning her features.

I Lied. The Luna Chapter.

Much like Twilight Sparkle, Rarity had a certain proclivity for anal. Mares of many different varieties had graced her bedroom specifically to please her appetites. From time to time, those stallions would go away a few thousand bits richer. For their silence. Her secret could not get out. Ever. If it did it would ruin her.

She would never tell her friends, save for perhaps Twilight who she could bond with over their shared love of anal. First, she had a date. She didn’t know who the mystery mare was, just that she wanted to meet in Canterlot. At a private location within the hedge maze. There was even a map. Looking it over, she noted that every turn was exact, as if a Pegasus had drawn it while looking at the hedge maze from above. And it was likely they had. Shivering a little, excited for her date, she stepped out of the castle and onto the back field where the hedge maze was located.

The last time she’d been here, it had been stolen away by Discord. He’d replaced it, exactly as it was. No new tricks or turns, no surprises. A simple hedge maze. She’d also been here with her friends. This time she didn’t dare bring them. If this mare were everything her letter promised, Rarity would be getting plenty dirty. In a manner of speaking. Shuddering in anticipation, she clamped her tail to her rear and stepped into the maze. Exactly like the time she’d come in here after Discord, the entrance was swiftly blocked by a wall of leaves and vines. The only way out was through.

Following the map she’d been given; she made her way through the maze quickly. When she finally reached the center of the maze, she was alone. “Have I been stood up?” she asked herself as she walked to the very middle of the maze. The small gazebo placed there was where the band would play at garden parties hosted in the maze. Everypony would be given a maze that would lead them here. Walking onto the gazebo, she looked around the garden. She was completely alone. Perhaps this was just a prank, or something much more sinister.

Mentally preparing a spell, she turned to prepare to leave when another pony was entering the garden. Princess Luna. No guards, no entourage, just Princess Luna. Rarity watched the Princess of the Moon approach and swallowed. It was midday, usually Luna was asleep by now, but she was awake and approaching the gazebo. Rarity could think of only two reasons, maybe three, that a mare who frequented the dreams of ponies would be awake after her duties had ended.

She wanted to spend time with her sister. No… if she had wanted that, she’d be in the throne room. Or wherever Celestia was at the moment. One thousand years separated could cause a strain on relationships, especially familial. Spending time together was the optimal way to mend that strain.

She wanted a picnic. No, she had no basket. A picnic required a basket of food and perhaps some sweet wine. Unless Luna was a dry wine sort of mare. Or a fruity wine. She seemed like the sort of mare who enjoyed a fruity wine. Like a Gamay or a Pinot Noir. There was no basket and no wine.

Was she here for a date? Was she being stood up as well? Curiosity getting the better of her, Rarity remained where she was as Luna approached. If she were being stood up for a date, this would make for some excellent gossip to share. With Applejack. Or one of the spa ponies. They could keep a secret. “Good Afternoon Rarity.” Luna said and Rarity realized that the princess was not expecting anypony else. She was there for her. Luna was Rarity’s date.

“Good… good afternoon Princess.”

“Come now Rarity, no need to be formal. We did not come here for formality, did we?” she asked and Rarity blinked. She was silent longer than Luna expected. “You have a… desire… you wish to fulfil?” Rarity blinked again before her alabaster cheeks turned an adorable shade of pink. “One that normal mares have begun to… lack in fulfilment?”

“I… believe… for that sort of talk, Princess, er Luna… I would like some…” she stopped as Luna’s horn lit and a small basket with wine and two glasses appeared. “Wine… thank you.” She said and the two mares, the royal and the fashionista, sat in the gazebo, hidden from the world by the hedgemaze’s distance from the castle.

“You may drink as you desire. As We said, We did not come here for formality.” Luna said and Rarity couldn’t help it as her eyes were drawn to Luna’s cutiemark. Her tail seemed to sway a little more actively. Less the magical ebb and flow like the tides and more a gentle swaying like she was trying to fan something. Catching herself staring, Rarity poured herself a glass and drank it. Though she remained dainty and polite, she downed the glass quickly. Luna merely smiled as she too began sipping her wine.

“Princess Luna… I must be blunt… is this a prank?” Rarity asked and Luna glanced at her with only one eye. “Rainbow Dash and Pinkie Pie have informed me of your… sense of humor and your love of pranks. I received a letter telling me to come here, alone, today. I had assumed it was a love letter, due to the perfume and…”

“Why woulds’t thou assume this is a prank? Yes, We shall admit to using just such a prank from time to time. On Our sister. She gets such a thrill when she thinks she has a date only to discover it is merely a distraction so We may strike her with a pie or a cake. Tis all in good fun. This is no prank, however.” She said and Rarity stared at her. “As you know, Our sister and Twilight Sparkle are… intimate. Twilight Sparkle likes to talk when she is relaxed. About her studies, about Ponyville… and about her friends.”

If Rarity could have turned any whiter, she did at that moment. Twilight talked about her friends. With the Princesses. “What… ehm… what did she reveal?” Rarity asked, quickly regaining her composure. She was having wine with a Princess, she needed to remain proper.

“Their secrets, when she is relaxed and has gotten some drink in her.” Luna said and Rarity had to stop herself from spitting out her wine. Not only would that have been rude to Luna, but this was quite good wine. And it was likely very expensive wine. “According to Twilight Sparkle, Rainbow Dash does not like having her hooves touched because they are more sensitive than most Pegasi hooves.”

“O-oh yes. Rainbow Dash does have the odd spa day with me from time to time. Her hooves are the one things she does not allow another pony, not even her dearest friends, to touch.” Rarity said, eager to steer the conversation in any direction other than at herself.

“And… Pinkie Pie. Food play is her… favorite? What, pray tell, is food play?” Rarity blushed but this was to be expected. Luna was still relatively new when it came to modern etiquette. Before she was sealed away, Ponies were more open.

“Food play is… well it’s… it’s hard to explain unless you’ve taken part but I can try my best if you would like?” Luna nodded, her face pensive, as if she were taking mental notes. “Food play is… well it is a sexual activity that involves food. One may rub… chocolate or honey into ones fur for their partner to lick off. Or… in the more sexual range of it… onto ones… special place…”

“Their teats?” Luna asked and Rarity blushed. She was certain her face was closer in shade to Pinkie Pie’s at the moment.

“Y… yes… their teats…”

“What other places? I am intrigued and wish to know more.” Luna said and Rarity swallowed nervously. Was it really ok for her to talk about that with a Princess?

“W-w-well… some ponies may pour melted chocolate or even whipped cream on their… uhm… I cannot think of a polite way to say it…”

“Then do not be polite. We are friends, are we not?”

“Certainly but…”

“We are also alone. Our guards will not interrupt us. Please, be a frank and clear as you desire.” The look on Luna’s face was sincere. Her guards were not around and, as she said, they were friends. Reaching out for the wine again, forgoing the glass, Rarity swallowed great mouthfuls of the, expensive, delicious wine. For courage.

“Some ponies pour melted chocolate or whipped cream onto their sex.”

“I see… and what of you?” Luna asked and all of Rarity’s borrowed courage was gone. Admitting that? To a Princess? Even if they were alone, Rarity would never be able to live down the embarrassment. “Come now Rarity. Would it help if I removed my crown, that you may see us not as your Princess but as your friend?” Luna asked and Rarity stared at her for a moment. Perhaps a moment too long. Coughing just slightly, she nodded and Luna removed her crown. In an instant, Princess Luna had vanished and Luna sat before her. Not a Princess, not even a regal pony. Her friend.

“I… like chocolate… on a mares… rear…” she admitted and, she had to admit at least to herself, it felt good to tell somepony. The only ponies who knew already were Lotus and Aloe, who were sworn to secrecy lest they lose Rarity’s patronage. Now Luna knew.

“I see. Does that not evoke images of… another… substance?”

“It did at first… but when I am the one pouring the chocolate it feels… different. I know that I put it there… so I know it is not… that.”

“Would you like to partake in an activity with me?” Luna asked and Rarity blinked. Before she could really respond, Luna teleported them both away. She wasn’t even sure they were still in Canterlot. Looking around, she took in a large, regal bedroom. Four poster bed with satin sheets, 500 count from the looks of them. Alabaster pillows the color of her fur. Silk curtains hanging from the top of the bed. Turning around, she froze. They certainly were not in Canterlot anymore. Not with several thousand miles between them and the planet. They were on the moon.

She didn’t even register she was not having trouble breathing. They were in a bubble of magic. Luna’s magic. Gravity was the same within the bubble and there was air. Plenty of air. And a breeze. Sure it was a magical breeze, but it was a breeze all the same. Turning to Luna, she froze. The princess was on the bed, melted chocolate pouring over her exposed rear end. “Come. Enjoy your treat.”

Rarity stayed rooted to the spot for a moment, watching the chocolate run down Luna’s cheeks and drip on the sheets below her. Drip… drip… drip… Every single drop falling off of her royal snatch like a slow rain. It took her a moment to realize that Luna had invited her to partake in the chocolate. It didn’t matter where it was, or the fact that she was a Princess. She was horny, Rarity liked mares and chocolate. That’s what mattered to her.

Luna remained facing forward, though her eyes did cast to the left and right merely out of a need to not look in a single direction for too long. She wasn’t sure how long she’d actually waited before Rarity’s lips met her rear lips. She wasn’t hesitating anymore, and she wasn’t being chaste. The alabaster unicorns lips were wrapped around Luna’s pucker and her tongue delved inside. There was no chocolate in there, but she was certain there would be soon.

The chocolate was running over her flanks, down Rarity’s muzzle and likely finding it’s way to her tongue and into Luna’s pucker. Rarity was only there for a moment before her tongue and lips found Luna’s sex, licking, sucking, and even nibbling the chocolate off. She wasn’t there long either, cleaning the midnight alicorn’s sex with her tongue before returning to her real target. Luna moaned as Rarity ate her rear. Her tongue played inside her pucker and Luna felt the unicorn’s magic wiping the chocolate off of her rump and legs, her delicate precise magic getting every last speck.

All of that chocolate went onto her rear only to be slurped away by the unicorn’s tongue and lips.

Unbidden, as if her body had a mind of its own, Luna jerked backwards. She was nearing orgasm, could feel it building inside her. Suddenly something was inside her rear. She knew what it was, and deep down she didn’t really care. The unicorn kept licking. She was forever thankful she cleansed herself regularly.

Magic was a tool. Unicorns and Alicorns used it to great effect. It was also excellent and keeping ones-self clean, inside and out.

Luna was certain Rarity knew where she was. It was hard not to when you were focusing on the outside of something you were suddenly inside of. But she kept licking. She kept tasting. A thought crept into Luna’s mind. Rarity had thought this a prank at first. How would she feel if the Midnight blue Alicorn took it an extra little step.

Bracing her rear hooves, Luna placed her forehooves on the head of the bed and pushed. Her rear strained and fought.

Pop.

It was almost comical. The sound her rear made as Rarity’s shoulders entered her. But now she had more purchase. The widest parts of a ponies anatomy were their head, their shoulders, and their hips. Sinking herself down slowly, she wasn’t really surprised or amazed at how easily her rear took Rarity in. She was more surprised at how much of her there seemed to be. When her shoulders went in, her forehooves were forced back against her sides, making for a slightly wider profile.

Eventually, she couldn’t lower any further and was forced to stand up, most of the alabaster unicorn inside her rear. She could use her magic to either push the unicorn in or pull her out. Or she could do it the old fashioned way. Looking around at the room they were in, her eyes fell on one of the posters on the bed.

She could press Rarity’s rear against that and push, moving her hips up and down as she went. The poster would rube at Rarity’s slit and slowly bring the mare to orgasm.

She could use her magic to shorten it, making it just high enough to stand comfortably over, and round off the top. Penetrate Rarity’s sex and bring her to orgasm before plunging her the rest of the way in.

A final thought crawled into Luna’s mind as she felt her orgasm building. Just push her in. Shove Rarity completely inside her ass and enjoy that full feeling for a couple of hours before letting her out to take a bath.

Any of those options, she was sure her current anal toy would greatly appreciate. The third option was the most pleasing as her orgasm approached with more intensity. Deciding on a course of action, Luna lit her horn, gripped Rarity’s hind legs, and pushed. Her stomach deformed slightly as the mare was pushed deep into her rear, her magic quickly removing her intestines in favor of the much more spacious stomach.

They weren’t gone, merely out of the way. If a medical examiner were to look at Luna’s x-ray right at that moment, her body would be mostly stomach. Lungs, heart, and other bits in her chest would be where they belong, but from her sternum beyond would be nothing but stomach. A simple spell, if one knew how to do it.

Luna paused for a moment to catch her breath before a loud, wet, belch ripped from her throat. All of her air had been forced out of her lungs by Rarity merely shifting around in her expanded stomach. Her spell shattered and she returned to the Garden. Panting, trying to catch her breath, she didn’t even notice she wasn’t alone.

“So… enjoy yourself aunty?”

A Third Chapter? For Shame.

Author's Note

I've got maybe one more in me after this. This one is staring Cadance, and a creature that I came up with off the top of my head. To picture the Slergen... think a giant gecko that walks on two legs.

A Third Chapter? For Shame.

Princess Cadance was always seen as the “perfect pink princess”. She was pink, she was the princess of love, and she’d married her long time sweet heart and ruled her own kingdom. She’d also bore a daughter who just happened to be an Alicorn.

She walked down the streets of the Crystal Empire and ponies waved or bowed. Her guards always remained two steps behind her, just far enough back that if she were attacked they’d be on the attacker in seconds. There were very few times she ever dealt with those attackers herself. It was usually Shining Armor’s job. That was how her day normally went.

Today was special. Today was her day. She’d ditched her guards and managed to perform a disguise spell to change her appearance. Flurry would still see her mom, so the infant wouldn’t worry, but everypony else would see just another crystal empire mare. Slightly taller than most, but that wasn’t unheard of. A unicorn, though there were plenty. Her crystalline coat was a slightly darker shade of pink, closer to Twilight Sparkle’s shade of purple. Her mane was a dull amethyst color.

She wasn’t really planning on staying out long, but she did have plans. She’d left instructions for Shining. If she wasn’t back in two days, don’t panic. Her trip simply took longer than expected. She had left a message saying she was going on a trip, for at least two days.

Nopony could actually guess where. When the unicorn mare was out of sight of everypony else, she teleported away, a bright flash of pink.

A similar flash of pink lit up a cave very near a rather large swamp she’d discovered on one of her solo hikes around the country. This swamp wasn’t the usual home to the typical Equestrian swamp fare; Hydras, Boggarts and the like. This swamp was home to more mundane creatures. Snakes, alligators, crocodiles and other normal beasts.

She wasn’t looking for any of them today. This particular swamp was home to one creature in particular she liked quite a bit. Hearing the tell-tale squelch of mud as giant feet slapped into it, she couldn’t help but quicken her gait. Slergens were such rare creatures, and this particular Slergen had an appetite for Pony.

Not the usual appetite, though he would gum on her a bit. Slergens didn’t have teeth after all, opting instead to swallow their meals whole, no matter what said meal was. Coming to a slightly more clear section of the swamp, she paused and peered through the reeds. Sure enough a large male Slergen was stomping through the mud. Most ponies, seeing a creature that large, would run and not look back. Cadance however wanted to watch him. She wanted him to see her.

Omnivorous creatures, Slergen would eat anything they could grab. Plants, berries, critters, ponies, it didn’t matter. Even the occasional Cragadile would disappear past their toothless lips. Feeling her heart thundering in her chest, she stepped out and made as much noise as possible. Another thing about Slergen was they were territorial. If this one was stomping around here, anything stepping into its mud hole was invading its territory. And it would be dealt with.

The sound it made was somewhere between a roar and a gurgle, sounding almost adorable as it squelched towards her. She didn’t run, but she did act like she was trying to escape from the sticky mud pit. When it was nearly on her, she moved and raced under its legs.

Slergen were smart. Smarter than a pony might think. If they couldn’t catch a pony with their squishy paws, they’d use their tail. Or, in this pony’s case, they’d simply sit.

Easily six times the six of a normal pony, of which Cadance was disguised as currently, the Slergen’s tail hole was more than a match for Cadance. She tried not to squeak in joy as its slimy, squishy rear came down on her. She’d wanted to go in head first, enjoy it a little, but she’d run a little faster than anticipated. Her rear legs got sucked in first.

Shrugging a little, she made a show of struggling. Just to alert the creature that she was there. It worked. Several muscle movements later and the only thing remaining outside of the slimy reptilian beast was Cadance’s head and forehooves. She didn’t have to move now, general muscle movement was slowly sucking her in.

Shining would never understand. Her face was pure bliss as she disappeared past the Slergen’s sphincter, sucked up into its bowels to be deposited in its gut. No pony would really, not even her aunt Celestia, whom she’d seen stuff a pony up her own ponut before. She’d always had a fascination with butts. Being in them specifically. Shrinking spells had become her friend before she’d married Shining. Mares, stallions, pets, it didn’t matter to her. Any butt was a butt worth being inside.

She still remembered the look on Chrysalis’ face during the wedding. Her look of confusion, then contemplation before finally deciding against it. Cadance would have happily let Chrysalis win, even filled her in on how to fool everypony, if the Changeling had done one thing. Allowed the Princess of Love to shrink herself down and crawl into the Changeling Queen’s rear, never to be seen again. She wasn’t sure why Chrysalis had decided against a permanent “love battery”, or why she’d let go of such an easy win.

Ultimately, however, Cadance was glad the bug queen hadn’t agreed. She wouldn’t have met this creature if she was living in Chrysalis’ ass.

A Pink Surprise, and Some Extra

She did it. She mustered up enough courage to talk to her friends about it. One of them at least. Just one. Who she swore to secrecy. Pinkie swore. No slip ups. It was time. She told her. She had to tell one of them at least. She’d need help with the others. She told her everything. From her time as Celestia’s cushion, including the night she spent in Celestia’s colon all the way up to Cadance revealing her own debauched mind.

She wasn’t sure what to expect. Would Pinkie run away, never speak to her again. Would she break her own Pinkie Promise and tell everyone?

“Can I try?” Pinkie’s words caught her off guard. Could she try? Try what? Try having Celestia sit on her? Spending a night in Celestia’s colon? “You know? Sitting on your face?” Twilight could practically feel the smoke billowing out of her ears. Out of all of her friends, Pinkie Pie had the plushest ass in their friend group. It had to be all of the cake and pie she ate. All that sugar had to be wonderful for your figure.

She didn’t even answer. Not that she could. Pinkie question had caught her so off guard, she’d forgotten to sit up straight. Her back was cold. She’d fallen over backwards, right off of the cushion. She was now on the cold floor of the crystal castle. She would have sat up. Really she would have. But Pinkie seemed to take Twilight’s “collapse” as a yes. That perfect pink ass hovered over her head for a moment before it came down on her.

Soft pink plushness surrounded Twilight on all sides. Her muzzle was as deep as it could get inside a pink ponut. She knew where her horn was, she was sure Pinkie knew where her horn was. Neither of them seemed to mind really. Pinkie sat there, still as a statue. Suddenly she started moving. Grinding her rump down on Twilight’s face. A hum reached Twilight’s ears. Was Pinkie thinking about this? Was she actually trying to decide if she liked using Twilight’s face as her personal butt plug and cushion?

Even if this wasn’t going to be a permanent thing, did she really like how this felt. Standing up, she looked at Twilight upside down as her purple princess friend drew in a much-needed breath. “I dunno Twilight. I think I need you deeper if I’m gonna see if I like it or not.” Twilight was about to ask what Pinkie meant when that perfect pink ponut engulfed her horn. And then just kept sinking. Twilight’s eyes went wide as it pressed against her head. She expected Pinkie to stop, adjust her position and try again.

A squelching sound reached Twilight’s ears as she realized she couldn’t see anymore. She really shouldn’t have been surprised. It was Pinkie Pie. One doesn’t question Pinkie Pie or her motives. Twilight’s entire head was inside Pinkie’s colon in moments. Pinkie squirmed and wiggled, testing out how it felt. Twilight was in bliss. Breathless, anal wrapped bliss. At least one of her friends didn’t think she was a freak for liking this sort of thing.

Suddenly she couldn’t feel the floor against her back anymore. Somehow her body was being moved, rigidly, with only her head in Pinkie’s ass. Where was she going? Not being able to see or hear was near agony. The sound of Pinkie’s hooves meeting the castle floor was loud and echoing, but also muffled. It was an odd sensation. Doors opened and Twilight felt them nearly close on her hooves. Pinkie had entered a room other than Twilight’s study.

Moments passed until Twilight felt something cold dripping on her body. She squirmed and wriggled, trying to figure out what it was, but Pinkie’s ponut had her head well and truly trapped. Gravity shifted and she knew she was now on her back, as was Pinkie, and that cold stuff was back, now dripping down her front and being rubbed in by Pinkie’s hooves. It still amazed her how flexible Pinkie could be, especially with somepony’s head encased in her asshole.

Twilight squeaked, the sound muffled by the walls around her, as Pinkie’s hoof found her teats and then her sex. Was she really about to help Twilight orgasm while she was like this. Then it happened. Pinkie started pushing. Both hooves were on Twilight’s sex, and she was pushing. Her shoulders strained for a moment before they slipped inside. After that it was quick. Ponies weren’t built like this; Twilight was absolutely positive about that. The intestines were long and winding, not straight and smooth. Yet within moments Twilight found herself curling up in Pinkie Pie’s stomach.

Twilight found she could look around pretty easily. Lighting her horn revealed Pinkie’s last meal, an entire pie, two whole cakes, and a hayburger. She had to remind herself not to question how Pinkie didn’t walk around like a balloon with legs with how much she ate regularly.

Hours passed and Twilight still hadn’t exited Pinkie’s stomach. She knew it had been a few hours because she had her own internal clock. It had been around lunch time when Pinkie stuffed her friend up her ass. It was sometime around dinner now. Was Pinkie going to eat again? Did she need to with Twilight in her stomach? Those questions and more passed Twilight’s mind, but one stuck. Was Pinkie going to digest her? She’d been in Celestia’s colon before, curled up as tight as she could get. She’d never gone so far as Celestia’s stomach.

“Pinkie! Let me out!” Twilight shouted, hoping her friend would hear. She didn’t know if she could, or should, use magic while inside Pinkie’s stomach. She didn’t want to hurt her. There was also the chance that trying to teleport would simply teleport Pinkie and they’d be in the same situation, just somewhere else.

Her surroundings suddenly shifted. She didn’t know what was happening outside of Pinkie’s stomach, but something was happening. Trying to push her hooves out against Pinkie’s stomach walls, she suddenly felt everything get tighter around her. Pinkie was in something. Was she in danger? Had she wandered into the Everfree and encountered a Cragadile? Or a Buffo? Was Pinkie being eaten by something dangerous? Twilight shook her head sharply. Being eaten in general was supposed to be dangerous.

Yet here she was. Having, essentially willingly, crawled her way into Pinkie Pie’s stomach. She willingly climbed into Celestia’s ass whenever she got the chance now, but this was different. Pinkie thrashed around her, struggling and fighting. Then she was out. Twilight was suddenly in Canterlot. In a bathtub. Blinking, she looked around. It was Luna’s private bath. Turning around she saw her rescuer. Princess Luna, with a belly full of Pinkie.

“Worry not Twilight Sparkle. She will not be harmed. Now, about where to put you for the night.” Twilight blinked and was about to suggest she just go home when Luna’s magic pushed her under the water, under her bulging belly and to her folds. Twilight tried to hold herself back, but Luna was just too strong. Twilight’s muzzle entered first, followed swiftly by the rest of her head. Within moments Twilight’s entire body was curled up in Princess Luna’s womb. “Fear not Twilight. We know you are our sister’s toy. We shall not keep you longer than tonight.”
