Celestia stumbled through the darkened corridors of the castle. She knew that this was not her own palace, but rather, one that was far older and more sinister. She could feel the very essence of evil permeate throughout, oozing forth from the stone walls and bubbling to the surface through the tarnished carpeting which was torn and rotten from age.

She’d been journeying for at least an hour now, though her surroundings had not changed in the slightest. It was an endless hall, with no doors, fixtures, or accessories to distinguish progress. She had no idea if she’d travelled a kilometer, two, or was simply stuck in space, walking upon some kind of complex structural treadmill.

Her horn was the only source of light, yet even her impressive magical reserves could only muster a small twinkle of illumination which barely reached the walls flanking her.

She did not know fear however. Fear was not an emotion that Celestia would allow herself. She had fought against wizards, tricksters, demons, and all sorts of villains that would put those three to shame.

In the distance, she heard a rock hit the floor, providing the only noise she’d heard that evening

“Show yourself!” Celestia shouted, bracing for an ambush.

Only, an ambush didn’t come as a sinister laugh echoed through the halls, coming from in front of her. It was familiar, yet Celestia couldn’t quite place a hoof upon where she’d heard it before. Yet, her memories of such cackling were painful and old.

She pressed onwards, her resolve doubled as her stumbling turned into a dedicated canter.

This bout of emboldened vigour proved to be just what she needed to finally break free, entering into a chamber of sorts.

It was equally darkened, with not even a single torch providing its feeble light. The only thing Celestia knew was that this space was large enough that her spell could not reach the walls, leaving her surrounded by nothing by a vast darkness.

She scanned her surroundings frantically, not knowing which direction bore safety and which had a villain lingering on the edge of her vision.

Then suddenly, there was light, as an impossibly large moon was revealed through a blanket the overcast clouds.

Apparently, this venue had no roof.

Soon enough, the space was lit, revealing that she was not alone.

Celestia yelped and stumbled back as she spotted her host for the evening, the source of that oh so familiar voice.

Nightmare Moon.

Only her sister’s alter ego was far larger than Celestia remembered, comparable to an adult dragon.

The demon opened one of her sapphire eyes, a perverse smile drawing itself upon her lips. It was wide enough that Celestia could see her pearly and pristine white fangs, each like a large marble stalactite hanging from a cavern’s roof.

A laugh rumbled forth from Nightmare Moon, the sound waves real enough that Celestia had to brace herself in order not to go flying away from the pressure.

“I’m so glad you could join Us, Sister,” Nightmare Moon murmured, opening her mouth as she yawned.

This gave Celestia a perfect angle to stare into the beast’s maw and see a fat tongue that was a deep purple in colour. It was a serpent’s tongue, with a forked tipped that really should’ve belonged to a reptile.

As the Nightmare smacked her massive lips together, she flickered the tongue, much like a snake.

“What do you want with me?” Celestia growled. “Why have you summoned me?”

Nightmare Moon smirked. “Us summoning you?” She shook her head. “We think you must be mistaken. We are here at your behest. Do you not remember?”

Celestia remembered making no such deal. The last thing she could reliably recall was retiring to her bedchambers after taking her evening tea with Luna.

How had she ended up here?

She glanced around.

Where even was here?

“We must admit,” the Nightmare droned on. “We are very much a fan of this new status quo. Now that We’re shed of that hag, you call a Sister, We’ve been allowed to grow, to really spread Our wings.” she did just that, fluttering her massive leathery appendages. “Aren’t We magnificent, Celestia?”

She grinned and stood up, taking a step towards her guest.

Celestia could feel a pulse of fear as she realized just how big her opponent was. Though she pushed aside such thoughts, knowing that fear would do her no good. She had tamed the sun and the moon, and those were far mightier opponents than this beast.

She attempted to channel her spell, to draw forth on either of those celestial bodies. However, nothing happened as her horn simply sparked out.

The Nightmare laughed, her size allowing for such a deep rumble. “We’re afraid that your magic doesn’t hold much power here. You are within Our domain, Celestia, and you’ll find yourself quite powerless against Us.”

She stopped before Celestia, breathing out. Her moist breath was hot as it rolled across Celestia form, causing her to wince as it blanketed her entire body in an unrelenting shroud of humidity.

“Look at you,” the Nightmare said. “You are hardly larger than an appetizer.” She grinned as she slowly shook her head. “Though We suppose such a tribute will have to do. As you can tell, there is very little within this realm to provide Us with sustenance.”

Celestia couldn’t help but whimper. “You aren’t thinking about…”

She was cut off as the Nightmare’s horn glowed, her telekinetic spell coiling around Celestia and hugging her tight. She could barely even gasp, let alone squirm, as she felt herself slowly lifted off of the ground.

Nightmare Moon opened her mouth nice and wide, filling Celestia’s world with an endless expanse of fangs, tongue, and the darkened flesh of her inner mouth. In the very back, was a uvula which bobbed as the Nightmare practically unhinged her jaw.

Celestia winced as she felt herself slip between Nightmare Moon’s lips, helpless against such an impressive beast.

She could feel the Nightmare’s teeth prod at her soft belly and back. She could feel heavy strands of saliva drip onto her face and coat her fur. She could feel the Nightmare’s cushioned palate as she settled upon it.

The Nightmare moaned and rolled her tongue around Celestia, obviously savouring the flavour of fresh meat.

Then, once Celestia’s hindlegs were past the Nightmare’s lips, the world was once again dominated by darkness as Nightmare Moon closed her mouth.

Celestia brightened her horn, feeling herself squeezed tight between the Nightmare’s wet tongue and the roof of her mouth. She could feel the textured grooves of cartilage grind against her as the Nightmare moved her back and forth, toying with her.

The forked tip of the Nightmare’s tongue slithered back, with surprising dexterity, and pressed between Celestia’s haunches, making her cheeks burn as it caressed a very sensitive part of her anatomy. Her magic momentarily faltered as she felt a shaky moan forced from her lips.

“Delicious,” the Nightmare rumbled, really poking and prodding at this most sacred of spots, milking it for every last drop of flavour. “The joys of eating your prey raw.”

Celestia whined, feeling an intense pressure settle within her gullet and a certain colour fill her cheeks as the Nightmare was unrelenting in her stimulation.

“Please,” she whimpered.

This only earned her a single note of bemused laughter.

Celestia tensed, feeling the billow of moist breath caress her as that amused note broke free from the Nightmare’s lips. She attempted to squirm, to gain even a degree of freedom, yet the demon pressed her even harder against the roof of her mouth.

She was pinned in place, feeling the cushioned tongue cradling her tightly. Though, while the Nightmare was firm, she still bore a surprising gentleness, not crushing Celestia like she clearly could’ve done.

Celestia’s fur was drenched, dampened by the saliva that now covered her and the thin trail of perversion which oozed down her quaking thighs.

As she breathed in, she could taste the Nightmare’s breath, thankful that her host had at the very least decided to enjoy some form of mint before proceeding with affairs.

“Well,” Celestia growled. “Are you going to eat me or are just going to continue to be uncivilized and play with your food?”

The Nightmare shook her head, causing Celestia to yelp as she was brought along for the ride, saved from flying around only by the tongue which pinned her firmly in place.

“No,” the Nightmare said, her voice coming from within Celestia’s very mind. “We are merely savouring Our food. It’s not Our fault that you’re some brutish barbarian who just shovels her meals away without properly enjoying them. Tell Us, do you even taste those cakes that are making you such a delectable treat?”

Celestia growled. “Bitch.”

“Takes one to know one,” The Nightmare replied.

Their banter did not continue for long as Celestia could feel the Nightmare’s tongue relax and her throat muscles flex. The absolute demon wasn’t even going to chew her cuisine, instead opting to merely swallow Celestia whole, like the venomous serpent she was.

Celestia attempted to scramble for a footing, her hooves trying to grip onto anything to save her from the Nightmare’s gullet.

Though, any attempt at gaining leverage, at fighting the inevitable, failed as she slid off the back of the Nightmare’s palate. Everything was too moist and slippery to really anchor herself to. And, with one final swallow, Celestia was pulled down the Nightmare’s throat.

It was a strange sensation, to be swallowed whole. She could feel the tight throat muscles all around her, cradling her in absolute darkness. As she attempted an illumination spell, all she could see was the darkened flesh of the Nightmare’s throat all around her.

The Nightmare’s muscles flexed, tightening, denying her even the smallest range of motion as she slipped a little further down. She could feel the air rush past her as the Nightmare breathed, her presence an obtrusion that caused her host to wheeze.

Her senses were alight with foreign sounds as she could hear the Nightmare’s body all around her. She could feel and hear the Nightmare’s pulse, this mighty beat that thumped around her through the endless network of neighbouring blood vessels. She could feel the Nightmare breathe, her throat relaxing every time she exhaled and constricting around Celestia like a vice when she drew in breath.

With each cycle of her lungs, Celestia slipped a little deeper, sliding slowly towards her final destination.

She could feel the warmth of her predator’s body, could feel the warmth of her stomach down below, with moist gasses rising and tickling at her hindlegs.

Suddenly she felt an aura around her, a purplish glow which belonged to the demon she was in.

It stopped her from dropping any further, freezing her in place as the throat muscles cradled her tightly, continuing their cycle of squeezing her and then relaxing. She squirmed feebly, trying her own counter spell, though such a thing was proven fruitless against the overwhelming might of the giant around her.

The Nightmare chuckled and from within her, the sensation felt so much stranger.

Celestia could feel the rumble of her frame, she could feel her breath rushing forth in mighty puffs, she could feel the amusement in a manner so intimate that very few individuals could ever truly understand it.

“Still playing with your food?” Celestia asked, pressing a hoof against the fleshy walls and pushing roughly, attempting to break free and take the final plunge.

At this point, she was resigned to being a meal. Though, she had every intention to go through with this on her own terms and deny the Nightmare the satisfaction of degrading her.

Her punishment for such disobedience was that the Nightmare’s magic began to intensify around her nethers, vibrating against her swollen lower lips.

Celestia gasped and threw back her head, accidentally pricking her horn into the side of the Nightmare’s throat.

“Watch where you’re poking that thing!” the Nightmare snarled within Celestia’s mind.

Celestia’s cheeks warmed as a feeble whine broke free. “S-sorry.”

Why was she apologizing to the demon who was eating her alive?

The magic pressed inside of her, filling her sex with the Nightmare’s potent essence. This magic took form, gaining tactility as it pounded slowly into Celestia’s sex.

All the while, the throat continued to cradle her, being more restrictive than any form of bondage. She closed her eyes and moaned, sensing the change in her predator’s demeanour. She could feel the Nightmare’s pulse quicken, just a little bit, her breathing growing a smidge more laboured.

Was she also getting off to this? Getting off to the idea of eating Celestia whole?

She was about to ask but the Nightmare’s magic denied her the option, instead doing little more than ripping a gasping moan from her lips. She shivered and shook, feeling herself being driven onwards at an unrelenting tempo.

“You absolute pervert,” Celestia breathed. “Are you… Are you seriously getting off to this?”

The Nightmare snorted, the breathy note breathless within her mind. “Why wouldn’t We? Do you know how powerful We feel at this moment? Knowing that We’re the only thing stopping you from plunging into Our stomach. You should thank Us for keeping you around for Our amusement.”

Celestia clenched her teeth and once again pressed her hooves against the Nightmare’s throat, attempting to press away, to put up even the smallest amount of resistance. At that moment, she wanted the Nightmare to choke on this meal, to know that she would not be some helpless maiden who would go silently into the night.

Yet, her resistance was only met by the growing vigour of the Nightmare’s magic. It was hard to resist when all she could focus on was how utterly complete the assault upon her nethers felt. It was like every single nerve within her cunt was stimulated, pressing her right to the brink of overstimulation.

Though the Nightmare was well-versed in the art, knowing Celestia’s limits well, always edging back as they neared this point.

Celestia cried out, her meek note of displeasure mingling with the Nightmare’s own breathing as she exhaled.

Her mind went blank, her body seizing as she felt herself driven so efficiently to the edge of bliss, to the pinnacle of pleasure, just dancing along the ledge that bordered the plunge into orgasm.

She didn’t know what to do or think? Everything about this moment felt so wrong, so tainted. She was not only being brought to an orgasm by her archnemesis, but she was being brought to an orgasm within her throat, feeling her body alive and active around her. It was humiliating, degrading, and Celestia couldn’t help but feel defeated.

This couldn’t be real, could it?

The magic pounded into her again, taking the form of a mighty stallion, ravaging her sex. She could lament nothing but the pleasure coursing through her body. She could lament nothing but the embrace of the Nightmare, whose body so utterly encased Celestia’s own.

A series of meek little noises oozed forth from her parted lip, her own feeble puffs of exertion melding into the ceaseless torrent that was the Nightmare’s own frantic breathing.

“I can’t…” Celestia groaned, gritting her teeth. “I’m going to cum.”

The Nightmare’s laughter filled both her mind, while also oozing past her as her throat shuddered with very real laughter. It was a demonic cackle, the amusement of an utter villain as she revelled her in her final victory.

“Then cum for Us,” The Nightmare hissed. “Cum for Us and know that We brought you to orgasm as We ate you. You are Our prey, Celestia, and know that your final orgasm belongs to Us.”

Final…

She could hardly comprehend the word as she felt the stallion once again buck into her, pushing her over the edge and into the sweet embrace of orgasm. She gasped loudly, crying out as she felt her juices squirt forth, staining her quaking hindlegs.

And just like that, the Nightmare’s magic faded and she swallowed again, dragging Celestia further down.

The deeper she went, the more intimate she got with the demon’s anatomy. She hit a point where she could feel the Nightmare’s heart through the esophagus’ muscles, feeling the mighty organ beat so potently right next to her like a massive drum.

A little further than that, she could feel the Nightmare’s lungs begin to expand and contract, these motions pressing down upon the muscles that encased Celestia, making those moist walls even tighter, hugging her to the point that their embrace almost felt crushing.

Celestia whimpered, knowing that her journey would not continue for much longer, at least, if her knowledge of equine anatomy was to believe. The lower she went, the warmer her prison got. It was heated by digestion and insulated by the fat and muscles of the body that surrounded her so utterly.

She began to sweat, as if she were in a sauna with a hot towel covering every inch of her body.

The Nightmare chuckled again. “Not much longer now.”

“Sh-shut up,” Celestia stuttered.

“Aww, are you done talking with Us now that We gave you an orgasm.” She felt the Nightmare shake her head, feeling it in the way her esophagus shifted around her. “We feel sorry for the stallions that you choose to bed. Do you simply pass out on them after your affairs are concluded?”

Celestia didn’t respond, wouldn’t grant this demon the honour of knowing.

Soon, she felt her hindlegs slip free of the tight muscles and into a relatively open space. The air that licked at them was so very warm, bordering on the realm of tropical with how much humidity it bore.

She kicked out frantically, feeling her body slowly pulled into this new chamber. A chamber she could only imagine was this demon’s stomach.

“No, no, no,” Celestia frantically chanted, trying her best to pull her way back up.

Only, the Nightmare’s magic formed around her once again, forcefully pulling her into this new organ.

“We should’ve chewed you,” The Nightmare grumbled. “You are quite the rebellious meal.”

Celestia fell for a few short seconds before splashing into something warm, watery, and slightly acidic. She winced, knowing where exactly she was.

Still, she needed to see it with her own two eyes and know for sure.

Her horn glowed, illuminating the new realm she was in.

She was in fact in the Nightmare’s stomach. The walls were a smooth salmon pink and she stewed in an abundant soup of acidic juices.

She gagged softly and decided that blindness was the better route to take.

Oddly there was no smell, or at least none that were putrid or toxic.

With no light around, the realm could almost be mistaken for a hot tub, or a sauna. It was so warm inside, with an almost oppressive humidity which seemed to embrace her from every angle.

Like with the rest of her journey, the sound of the Nightmare’s body accompanied her. The beating of her heart, the expanding of her lungs, and the creaking of nearby joints and muscles were constant company.

Occasionally, a cool breath would leak in from above, caressing her face and doing away with a tiny amount of the oppressive heat.

“I left you a present down there,” the Nightmare said, her voice flittering through Celestia’s mind.

Celestia sparked her horn and noticed that there was a cooler floating about a metre away. She half-paddled, half-shimmied towards it and popped open the lid, finding an assortment of beverages inside.

“What?” Celestia asked, mystified as she shook her head. “Why?”

“We thought you could use a cool drink while you’re down there. We can only imagine that it’s a little warm in Our stomach.” The Nightmare chuckled. “You’re going to be down there for awhile, after all.”

Celestia sighed and levitated over a rum cooler, popping it open and taking a sip.

“Thank you… I suppose.” She shook her head. “Though, shouldn’t I be digesting by now.”

“Oh, you are! It just takes a very… very long time.”

Celestia nodded and drew in a breath, enjoying another sip.

“Did you enjoy the magic fucking?” the Nightmare asked.

Celestia snorted. “I will admit that the sensation was a little strange, especially with… well all of this going on.”

She could see that ethereal purple aura float around within the stomach, gliding around in tendrils like an aurora. It offered a minute amount of lighting and was actually pretty soothing, distracting Celestia from the slight tingle that tickled at her hide.

Celestia closed her eyes and drew in a breath.

Was this the end? There had to be some way out of this, right?

Her eyes snapped back open.

Maybe there was!

Her gaze returned to the plastic cooler and she cautiously opened it, noticing just how much alcohol was inside.

How big was the Nightmare?

She quickly went over some mental math, punching in a likely body weight and comparing it to the amount of alcohol available.

Celestia smirked.

She loved when a plan came together.

“I do have a question for you,” Celestia said, feeling her confidence returning even as the stomach acid slowly did away with her coat.

The Nightmare snorted. “And what’s that?”

“Are you the same lightweight that my sister is or does your taint bestow alcoholic tolerance?”

“We’d… We’d prefer not to answer that,” The Nightmare stammered.

Celestia nodded and lifted the cooler’s lid, using her magic to open every single bottle that was inside.

“I still remember that first time Luna overindulged in mead and I had to hold her mane back,” Celestia said before letting out a heavy sigh. “Maybe not the cleanest way to get out of this but…” Her gaze narrowed. “I will not be your food tonight, Nightmare!”

She upended the bottles, pouring a mixture of sugary juices, ale, rum, and even a straight litre of vodka into the puddle that surrounded her.

Almost immediately, she felt her predator shudder violently and the Nightmare made a very displeased noise.

“This is what We get for showing kindness,” The Nightmare groaned before promptly dry heaving.

The stomach convulsed, once, twice, and finally Celestia felt herself getting shot up towards the entrance on a wave of something she didn’t want to think about.

“We will not be so kind tomorrow evening,” the Nightmare snarled, her voice sickly within Celestia’s mind.

Tomorrow evening?

What did she mean by…

Celestia jerked awake, bathed in a cold layer of sweat.

“What the fuck,” she murmured, looking around and confirming she was in her royal bedchambers.

One of her guards, the one snuggling her, stirred. “Is something the matter, Your Majesty?”

Celestia shook her head. “Nothing to concern yourself with, Sirius. I just… I had a rather strange dream.”

He nodded and closed his eyes. “You should talk to your sister about that.” He smirked. “I heard she might be an expert in the field.”

Celestia bit her lip, not wanting to admit that her sister played a key role in her current bout of insomnia.

But what had just happened was merely a troubling dream, correct? That wasn’t really Luna, nor was that really the Nightmare. It was… a figment of her imagination, a mixture of stress and…

“I’ll be right back,” Celestia whispered. “I’m just going to take a quick stroll to the kitchen to help clear my mind.”

Sirius didn’t respond, as he was already fast asleep, snoring softly.

Celestia shrugged away from him and headed towards the door, stepping into the hall. From there, she took the brief trip towards the royal kitchen.

As she silently stepped inside, she paused, noticing that her sister was also there, currently fixing herself a cup of herbal tea.

Celestia felt a terrible pang of awkwardness, though tried to shove aside such thoughts. This was not the Nightmare, this was Luna, her sister, a pony who would not swallow her whole in some strange combination of sexual fetish and appetite.

“I didn’t know you drank tea,” Celestia finally said. “Finally giving up on coffee?”

Luna jerked to attention, allowing herself a tight smile as she took a sip. She left the bag in the cup as she drank it; a monstrous practice, but one that Celestia would reluctantly tolerate.

“No,” she said, placing the cup down. “Just had a bizarre bout of ingestion is all. Certain dreams can have some pretty curious effects upon me when I’m on duty.” She frowned. “Though why are you awake? Hopefully nothing has been plaguing you.”

Celestia tensed. “No, no, just had some troubling dreams that I needed to reflect on.”

“Anything I could assist with?” Luna asked, offering a smirk that Celestia couldn’t help but feel was a little too coy for her comfort “Dreams are my area of expertise after all.”

“I don’t believe that will be necessary, Sister,” Celestia said, shaking her head. “There are plenty of other ponies who could better use your services. I’m sure that a little warm milk will be more than adequate for me.”

“Of course, of course.” Luna took another sip of tea. “Though if they do persist, let me know.”

“I will make sure to do that,” Celestia said.

Luna nodded and headed towards the pantry’s exit. “Have a good night, Tia.”

“You too, Lulu.”
