Celestia once again found herself within the nocturnal palace’s eerie corridors.

Small things had changed since her last visit. The carpeting, while still worn, looked several years fresher, being mostly intact and merely faded. The walls were also now decorated with fixtures and paintings, all of which was covered in a thick layer of dust. While an upgrade, Celestia had long ago discovered that they had an established pattern, with the hallway repeating.

She knew that this was a dream, yet she couldn’t do anything about it. She had tried all of her tricks for waking up, bonking her head against the wall and applying a caffeination spell to her blood supply. Whatever was keeping her in this domain did not want her to leave.

Was this really Luna, would Luna truly do something of this nature? And if so, why would she do this? As a jest? Or as a legitimate means of terror?

Celestia shook her head, finding the idea hard to believe.

Yet, if the dream put her in the same destination, it must also mean that the narrative was going to be similar. She was going to be swallowed whole again and needed to prepare an exit strategy, as she doubted that this demon would offer her such an easy escape route again.

She sighed and looked around, trying to determine how to speed things along, growing quite bored of seeing the same semi-rotten portrait for the hundredth time.

“Hello?” she called out, standing still. “Are you going to make me tire myself out before we convene?”

Laughter rumbled forth.

“We weren’t even aware you were there,” the dark voice flittered forth.

Liar.

“Are you here to try your second attempt at eating me whole?” Celestia asked, stepping forwards.

She was pleased to see that the hallway immediately gave way and led into the familiar vast chamber.

The Nightmare chuckled. “Why are We here? Celestia, you are the visitor within Our domain.”

“Yes, but your domain is within my dreams.”

There was no toying around this time as the moon was quickly exposed, without theatrics, filling the chamber with light. Like with the hall, the chamber had gotten a renovation, doing away with at least a century of wear and tear. Though, Celestia’s attention only briefly picked up on this as Nightmare Moon revealed herself.

The Nightmare was lounging on her back, looking quite lazy. She smacked her lips loudly together and made a show of yawning as she scratched at her slender belly.

This new position allowed Celestia to see something quite fascinating. The Nightmare apparently had a sheath and a very heavy set of balls, instead of the anatomy that one would commonly see on a mare. At least, on a mare that Celestia knew was one from birth.

“Huh,” Celestia murmured, shaking her head.

The Nightmare cocked a brow. “Is something the matter, Celestia? You look…” she grinned, “distracted.”

“I did not expect you to have…” Celestia’s cheeks warmed as she realized what she was about to say. “Nevermind…”

The nightmare grinned. “A penis?”

“Well I wasn’t going to be that crass and just say it,” Celestia murmured, looking away.

“This is a dream, Celestia,” The Nightmare said, her magic coiling around her prey once again. “We can give ourselves whatever anatomy We see fit to equip Ourselves with. We can have a stallionhood, a maidenhood, or anything that Our imagination could possibly muster.”

Celestia grunted, squirming against the Nightmare’s oppressive spell. “Does that mean I could also do whatever I want?”

The Nightmare shook her head, bringing Celestia directly in front of her maw. “We’re afraid not. We are the queen here and We only grant you as much autonomy as We see fit.”

Celestia looked into one of those massive sapphire eyes, watching it narrow like some kind of feline. She was prepared to slip into that massive maw again, to be swallowed whole. Though considering her rebellious spirit last night, she had a feeling that the Nightmare might opt to chew her cuisine this evening.

In that case, this would be a rather short dream.

Only the Nightmare did not open her mouth, instead allowing herself a playful smile. One which showed off rows of razor-sharp teeth, each like a massive limestone spike upon Canterlot’s battlement.

“And an interesting part of controlling reality is that We can also control some very basic concepts of biology, altering how bodies work,” The Nightmare said. “We can absorb your nutrients in all sorts of very fascinating and humiliating ways.”

Celestia gasped as she was spun around, facing the Nightmare’s lower half. The giant mare was pawing at her sheath, edging her pride forth. Like the rest of her, it was dark, being a rich midnight purple with splotches of ebony black.

As the Nightmare stroked herself, she moaned, her pleasured note oozing forth and caressing at Celestia’s back in a blanket of warm euphoria. Inch by inch, she brought her erection out, letting it flop upon her belly.

The cock was truly impressive, being several times larger than Celestia’s body. Yet, it was also far larger than it had any right to be, being proportionality massive compared to the Nightmare’s already impressive stature.

It wasn’t fully erect yet, but the unflared tip was exposed and the medial ring looked incredibly thick.

If she were a mortal pony, and this was reality, such an organ would surely make her pass out due to the inevitable blood pressure drop. Though such laws of common sense and reason apparently did not hold jurisdiction within this accursed palace.

As the Nightmare continued stroking herself, she floated Celestia away from her face, gliding her towards her fat cock.

Celestia frantically squirmed in her magical bindings, struggling with renewed resistance. Though, she found such efforts to be largely futile. The magic was too omnipresent, too powerful to make any attempt at rebellion feasible. She really should’ve learned that after last night.

Was the Nightmare going to fuck her?

if that was the case, then Celestia’s dream would not have an especially long narrative considering how petite she was compared to that monstrous organ.

As she neared the cock, she drew in a frantic breath, a puff of exertion. Upon it, she could smell the overwhelming musk of the Nightmare’s erection. It smelled of virility, of masculinity, of filth and lust. Celestia couldn’t help but blush, feeling blood pulse within her loins. After all, it was also a smell that Celestia was familiar with, having enjoyed her fair share of male suitors in the past.

“You could’ve bathed,” Celestia growled.

The Nightmare snorted. “You do not fool Us, Slutlestia. We have access to all your darkest little fantasies and We know how you enjoy your cocks.” Celestia could practically hear the smirk. “We will admit that we were a little shocked to learn about your musk fetish. Along with all the other ones you have. Such a degenerate little imagination…”

Celestia’s face burned. “Oh please, you of all ponies should know what eternal life does to your sex drive.”

“We wouldn’t know,” the Nightmare murmured. “You locked Us away for a thousand years with nothing but curious shaped moon rocks to keep Us company in a carnal sense.”

She hovered Celestia further down, gliding her over the massive pulsating cock and giving her a rather intimate view of it. With every second, it grew a little harder, a little more exposed.

Celestia could see that a potent drizzle of pre had bubbled to the tip, staining the Nightmare’s coat with an impressive ration.

In the end, Celestia’s final destination was the Nightmare’s heavy sack, each of her balls the size of a large boulder, easily dwarfing her in size.

Unceremoniously, the nightmare crammed Celestia into her sweaty hide, pinning her forcefully against one of her balls.

Celestia gasped, feeling almost dizzy as she was assaulted from every direction by the overwhelming musk of the Nightmare. It was more potent and intoxicating than any stallion Celestia had the pleasure of being with. It was a universal constant, tainting all of her senses in a shroud of pheromones.

She whimpers softly, feeling the Nightmare’s magic crawl along her inner thigh, ticking at the sensitive flesh as she trailed her spell up towards her sex. For the second night in a row, the nightmare teased Celestia’s lips, playful stroking at her already glistening folds.

“You filthy pervert,” the Nightmare grumbled. “Already a soaking wet mess. How does Equestria manage with such a depraved harlot on the throne.” She snorted. “And to think, you had the guile to stop Our rightful claim to leadership.”

Celestia couldn’t respond, couldn’t muster so much as a single note as a rebuttal. Her world was so utterly dominated by the Nightmare’s musk, her mind just left blank and helpless in the face of this raw sexual presence.

The Nightmare shook her head. “Drunk on Our pheromones, are you?”

She drew Celestia away from her balls, earning a pathetic whimper that even the addled Celestia knew sounded desperate. Though, she was not moved far as she was pressed against the base of the Nightmare’s slick cock.

Once again, the world became one of pheromones, one where sexuality and perversion plied at her from every angle.

The Nightmare’s spell wound around her like a talon, pressing her firmly against her quivering erection. She moved her up and down, stroking her along like some kind of accessory to masturbation. Celestia felt humiliated, her cheeks burning as she was used in such a fashion. Yet, she could not help but revel in her perversion, in the knowledge of being treated in such a lowly fashion.

Faster and faster the Nightmare stroked, moving Celestia along with increasingly potent strides. Before long, Celestia felt the medial ring bump against her belly, as she soon found herself moving towards the very tip. Here, the feral smell was at its strongest. This was the epicentre of the Nightmare’s perversion.

The Nightmare rolled Celestia around the tip slowly, covering her fur in a thick layer of pre. It was sticky and potent, coating every inch of Celestia in a bukkake that not even a dozen guards could ever hope to replicate.

Not that she knew anything about that.

After she was absolutely drenched in the Nightmare’s bodily fluids, she was drawn back down and the stroking was renewed with surprising vigour. The magic was much smoother than before, the pre acting as an ideal lubrication and allowing Celestia to slide along the Nightmare’s cock far more fluidly than before.

Celestia gasped and went limp, whining as she felt the Nightmare’s magic around her haunches. It was pushing and prodding at her swollen lips, teasing them mercilessly.

“We are nearly ready,” the Nightmare moaned, her own voice haggard.

Ready for what?

Celestia closed her eyes, trying her best to think of what the Nightmare had in mind. Her current tactics were smart, leaving Celestia far more addled than she was prepared for, putting her on the backhoof for whatever lay ahead.

Slowly, she was brought back to the tip and then beyond it as she was finally removed from the Nightmare’s intoxicating erection. She breathed in the first whiff of fresh breath she’d been allowed since this perversion began.

Was the Nightmare going to consume her when she was covered in bodily fluids? The idea was far too disgusting, even for this demon.

But instead of being brought towards the Nightmare’s mouth, which bore an ever-present sinister smile, she was brought back down, hindlegs first.

She glanced at her hooves and noticed that she was hovering over the Nightmare’s potent erection. The tip belched another strand of slick pre which rolled down the unflared tip and along her quivering shaft, the white contrasting so nicely with her darkened flesh. Celestia could see that the entire length was dampened, her presence being used as a very literally cumrag to spread this natural lubricant.

“I doubt that it’s going to fit,” Celestia grunted.

The Nightmare smirked. “And who said that We were going to penetrate you?”

Celestia was confused for a moment until she felt her hindlegs poke at the hole on the tip of the Nightmare’s erection.

“Wait…” Celestia whispered, finally realizing what was about to happen.

The Nightmare grunted, applying a bit of force.

Celestia gasped, feeling her hindlegs spread this hole and slip into the Nightmare’s urethra.

She attempted to squirm, though the Nightmare’s magic was even less forgiving today.

“Our apologies,” she murmured. “But We can’t have you kicking around during such a delicate operation.”

Celestia whimpered, feeling herself slowly being pressed inside, like some kind of organic sounding round. Inch by inch she went deeper, feeling her hindlegs, and then belly, slip past this point. Her forelegs were pinned to her side and they slipped into this impossibly tight hole with her torso, putting up only the barest amount of resistance. With this, only her head was left free as the Nightmare ceased any further penetration.

Celestia grunted loudly and attempted to squirm, though the muscles and flesh of the Nightmare’s urethra were a far better form of bondage than the lining of the esophagus she had traveled through last night. It was like being trapped within a vacbed, with the latex not giving her even the tiniest sliver of freedom.

Celestia narrowed her gaze, glaring at the Nightmare who looked very powerful from her current position.

“Do you always play such perverted games with your prey?” she growled.

The Nightmare chuckled. “It depends how frequently We get them and how ravenous Our hunger is. You’re in luck, for we managed to feed after your display last night. So, We have plenty of energy for Our games.”

The Nightmare reached down with a hoof, prodding the very tip of it against Celestia’s forehead. “Maybe if you beg, We might be prone to showing you a little mercy.”

Celestia growled and attempted to bite at the hoof, like some sort of caged animal. Sadly, her teeth were blunted and the hoof was made of pure calcium, meaning this attempt at rebellion would not amount to much more than a sharp pain radiating through Celestia’s jaw.

“My, my, my, someone is being quite the rowdy pony tonight,” the Nightmare chided before her cocky smoulder returned. “Though before We forget; We do need to do one little thing.”

She poked at Celestia’s horn and the appendage disappeared. It didn’t hurt or ache, merely leaving Celestia with an overwhelming sense of wrongness. Her mane remained, and she could still feel her connection to the magical aether, but when she attempted to channel it, nothing formed around her.

“Don’t worry, Celestia,” the Nightmare said. “You’ll get that back in a little while, We would just prefer if you didn’t have it during your journey. Our anatomy is… sensitive and that horn is rather sharp.”

And with that, the Nightmare’s magic pressed down upon Celestia, unceremoniously plunging her head into the urethra’s embrace.

Celestia gasped for breath and looked up, seeing that tiny pinprick of light above her. It inched away as she was slowly pulled down, growing fainter and fainter.

It was claustrophobic in the Nightmare’s cock, Celestia essentially paralyzed by the tightness of her confines.

She breathed in her through her nose, feeling some form of relief that she could at the very least still do this. Though as she breathed, she discovered something in the air, a certain pheromone that prickled at some feral part of her mind.

This part flared up, crying out and begging for something instinctual and carnal. This smell caused her nethers to warm and grow inflamed. It was like going into heat multiplied by some ungodly factor. Her mind begged for her to get bred, begged for some form of relief from the heat that was rapidly dominating her body, corrupting her mind.

She tried to reach down with a hoof, doing her best to stimulate herself. Though the walls around her denied her even this smallest action. It was torture as if every nerve was crying out, begging for her to be used like a sock by a teenage colt.

Lower and lower she ventured, and as she neared the Nightmare’s balls, the perverse smell became stronger, dominating any attempts at sound judgement.

Celestia could hear the Nightmare laugh. She could hear the cackle within her very psyche.

“Can’t think of resistance with cock on your mind, can you Celestia?” her nemesis chided.

Celestia, who couldn’t even think of a response due to this sensation, could only offer a feeble grunt.

Lower and lower she went, edged along by the Nightmare’s magic. Soon, she felt her hindlegs press into a more spacious abode. Though one that was far warmer and more humid. It was like the stomach, though even more oppressive in its intensity.

Not that Celestia could really lament such things, with her mind in such a perverse state. All she could think about was the fire which would not cool off, would not dissipate or wane. She rubbed her hindlegs together in a desperate effort to give her anatomy any form of stimulation, yet all this did was leave her wanting for more.

Finally, her belly broke into this new chamber and her torso after that. When both were free, she plopped out of the urethra and splashed into a puddle of something thick and viscous.

At that moment, her horn returned to her and she sparked it, seeing that her new confines were utterly plastered with cum.

She bathed in a vast puddle of it, the dark walls were coated in it, the air was heavy with the intoxicating scent, and it was so omnipresent that she could even taste it upon her lips with every breath she took.

Now that she was free, she took no time in sating her carnal desires. She reached down with a hoof, plunging it into the pool of semen and pressing it against her haunches. She rubbed at herself frantically, using her magic to enhance the experience by casting a warming charm upon her frog.

Celestia moaned like an utter whore, closing her eyes as she edged herself rapidly towards whatever objective her instincts were guiding her towards.

“You depraved whore,” the Nightmare teased, her voice the only rational one in Celestia’s frantic mind. “Does being absorbed really get you off that much?”

Absorbed?

Celestia attempted to concentrate upon that word, though found that her senses would not allow her to do such a thing. The Nightmare’s influence was complete and utter, filling her thoughts with nothing but a constant nagging voice that beseeched her to continue stroking at her folds.

She gritted her teeth and groaned, a moaning voice flittering free as she continued to press against her sex. Faster and faster her hoof went, fueled by the constant fire within her snatch that begged for blissful relief.

On and on she went, edging herself ever closer. She could feel herself balancing on the precipice of pleasure, brought there so quickly by the constant blanket of pheromones that smothered all semblances of common sense.

In the back of her mind a voice cried out, trying to warn her, a voice that noticed some peculiar things happening to her. She wasn’t fully aware but a part of her noticed that her body, or at least that below the cum line, was feeling a little less solid than it once was, a bit gooier if that made sense.

Still this did not stop her from rubbing away, focused so utterly on stimulating her swollen pussy.

She was so close, just dancing on the brink of utter ecstasy. A little more and she’d be over the edge and into the realm of nirvana.

She slipped a little lower into the Nightmare’s cum, noticing that the deeper she submerged, the more intense her pleasure felt.

So close.

Celestia heard the Nightmare cackle but forced herself to ignore such taunts. They weren’t important, the only thing that was important was getting off, dealing with that heat in her loins.

She tried to breath but found that such things were no longer feasible. That probably should’ve been concerning but Celestia’s utter devotion towards getting off made worrying an obsolete concept.

“So close,” she murmured, her voice wet and sounding very distant and faint.

She sunk a little deeper into the cum bath, continuing to stroke away with all the vigour she could possibly muster.

Why wasn’t she getting off? This was torture?

Then she realized that there was only one way that she was getting off, one way to actually achieve climax in this prison.

She sunk below the cum, submerging herself fully within the thick broth that filled the Nightmare’s heavy sack.

And it turned out that this was the key, this was what finally tipped her over the edge. She gasped, though she no longer had lungs to do so as she came. She came hard and with such impossible vigour, her mind alight with a million neurons all firing off with a level of ecstasy she thought was beyond the realm of what was possible.

This orgasm was more intense than any she had ever felt, so complete and utter. At that moment, it seemed like the only thing in the world that mattered was the sheer pleasure that clouded her mind and muddled her judgement.

And as she came, so did the Nightmare, her nemesis moaning loudly.

Celestia, or what was left of her, lurched forth, gushing through the urethra she had so recently been pushed through. She no longer had sight or any senses beside touch and sound. Yet that touch was euphoric as she felt herself launched into the air, her new gooey form splattering against the Nightmare’s belly as she was sprayed forth in a mighty cumshot.

The Nightmare chuckled as her orgasm finally waned, her chest rising and falling rapidly. “The score is one-one, Celestia.”

One-one?

Celestia jerked awake, gasping for breath.

“What… WHAT THE FUCK!” she shouted.

Sirius bolted away, flaying about. “I’m awake! I’m awake! What’s the emergency?”

Celestia blushed, shaking her head. “Sorry, sorry, just another bizarre dream.”

“I see.” Sirius thumped back against his pillow. “I’m telling you, Your Majesty, you really should go to Luna about this.”

“I’ll…” Celestia bit her lip. “I’ll consider it, Sirius.”

When no response came, she looked over, snorting as she noticed that her bedmate was already asleep.

When sleep did not return to her so easily, she got out of bed, sighing as she went over what had just happened.

She had just had a dream where she’d been turned into semen within her sister’s ball sack. Or well… her sister’s alter ego’s ball sack.

Just thinking about that sentence hurt Celestia’s head with the sheer mental gymnastics she had to perform.

She did know two things, however. First, the dreams were intense and vivid, being memorable long after the event. Second, the dreams apparently did not have an effect upon her physical form. This was good, as she preferred not being turned into cum.

At the thought of that, she became aware of something.

There was a very real wetness leaking down her hindlegs.

She shook her head, trying not to lament on this as she walked into the royal kitchen.

For a second night in a row, she froze, seeing Luna already there.

“Good evening, sister,” Luna said, not even looking at her. “Trouble sleeping again?”

Celestia nodded, moving towards the fridge and pressing her tail tight against her haunches as she did so.

“Another troubling dream,” she admitted.

“Two nights in a row?” Luna asked. Her voice didn’t betray any emotion.

Celestia nodded.

“Would you like me to visit you this evening and see if I can be of assistance?” Luna offered.

Celestia shook her head, grabbing a carton of milk. “Our folk remedy helped last night and we will attempt to use it again.” She then looked at Luna, noticing what she was preparing. “Is that a glass of pineapple juice?”

Luna nodded. “We felt a little deficient in vitamin C.”

Celestia pursed her lips, remembering something Sirius had once told her about that specific fruit and its ability to improve a certain kind of flavour.

She didn’t dare breach that topic of conversation with her sister, however.

“Well enjoy you glass of juice, Lulu,” Celestia finally said.

Luna nodded. “And you enjoy your milk.”
