“Um…M-Mistress?”

Nightmare Moon’s eyes flicked up promptly from the book that had previously been the object of her attention. The calm of the moment had been summarily broken, alerting her to her surroundings, the crackling and popping of wood in the fireplace, the tromping hoofsteps of a pony approaching. The rotund mare stood in the corner, as if trying to push herself in against the wall, to make herself less noticeable. A difficult task given her immensity.

“I instructed that I was not to be disturbed, Rainbow Dash,” the alicorn grumbled, the words growling in her throat, just loud enough to be audible across the chamber.

“I am…yeah, I know,” the cyan mare replied with a labored sigh, “but there was a…well, you received something.”

That piqued Nightmare Moon’s interest and curiosity, and as she watched Rainbow Dash revealed an object which she had been holding tucked against the side of her gut. It was a package, covered in wrapping paper, rounded and oblong like a partially collapsed cylinder, a shape that at first made her think of a telescope. As she stood, though, and the maid came closer to place the parcel upon the desk that stood between them, the larger end facing down, her evaluation shifted. She picked up the object in one hand, fingers partially grasping around the wider end, and she discerned its contents shift in a distinctly liquid fashion, sloshing about—a bottle, then, in all likelihood. The packaging was brightly colored, clashing with the midnight tones that made up most of the palace (even the fire in the fireplace was ghostly blue), red and white and green, and there was a bit of gold twine wrapped around the top of the bottle, keeping the paper sealed, with a folded piece of cardstock dangling from it. She lifted the card and read on the front of it “Happy Hearth’s Warming.”

“Oh, Hearth’s Warming, that’s right…” Nightmare Moon muttered to herself, a thin, nostalgic smile creasing across her muzzle, “I keep forgetting about it, truly.”

Then she opened the card and read the interior.

Dear Princess Moonbutt,

I sure hope you don’t still have a stick wedged firmly up your ass, but just in case you do, here’s something to help you loosen up. It’s the least I could do for a pony who’s livened up the country so much in such a short time.

Sincerely yours,

An Anonymous Fan

The glib, disrespectful tone soured her somewhat, but the thought of somepony who genuinely admired her efforts was enough to keep her on her ever-volatile good side.

“And we have no knowledge of who sent this…gift?” she asked while continuing to turn the package about in her hands.

“Um…n-no, Mistress,” Rainbow Dash admitted, gaze turned downward, “it was simply found in the reception hall next to your throne. Nopony was seen leaving or entering to place it there. The investigation is currently ongoing.” She spoke that last sentence with a certain wistful longing, as if regretting that she wasn’t involved with said investigation herself.

“Hmm…I see.” Nightmare Moon then proceeded to tear the wrapping paper away, revealing what she had suspected: a dark glass bottle, its murky contents faintly visible within, churning about. “Well, I’d best inspect it for myself then,” she declared while twisting on the stopper.

“Wh-what?” Rainbow Dash sputtered at her in disbelief. “B-b-but, Mistress, that can’t possibly be safe! It could be poisoned! You can’t afford to—!”

“Excuse me, Rainbow Dash,” the alicorn curtly interrupted, and in that moment it seemed as if her full height was that much more than the pegasus before her, looming over her despite her more willowy frame. “Since when does a lowly maid tell me what I can or cannot do?”

She blanched and promptly bowed her head in supplication. “F-forgive me, Mistress, I didn’t…I j-just meant…it could be d-dangerous!”

“Oh I doubt it,” she said with a smirk whilst continuing to examine the bottle, “no self-respecting winemaker would allow their product to be adulterated in such a way. And it would be so antithetical to the spirit of the holiday, too. Perhaps you should stick around, if you’re so worried; then there will be somepony present to take responsibility for the incident and ensure that I do not expire. You can handle that, can’t you?”

Rainbow Dash stared back, baffled. “I…y-yes?”

“Very good.”

Then Nightmare Moon finished twisting the cap off the bottle. She held the opening up to her nostrils and sniffed a deep breath of the sweet aroma that came wafting out. She was a regular connoisseur of the wine industry, but this particular concoction did not immediately line up with any comparisons in her memory. There was something about it, though, that elicited an electric tingle of anticipation in her brain, enticing her further. Her loins twinged with newfound desire.

Since the wine was a gift to her specifically, it stood to reason that there was no need to bother with the formality of a glass, so she simply tilted the whole thing back toward her open mouth and began to drink. The sweet taste washed over her tongue, and she allowed it to fill her maw for several seconds before she stopped long enough to swallow and to exhale a contented, purring breath. “Oh, stars above, that’s the good stuff,” she remarked, syllables extended slightly in satisfied moans, “now this is a real Hearth’s Warming gift. When we figure out where this came from, we should make them do this every year.” She paused in the middle of starting to drink again and added, “Or every month. Every week. Every day? I’m certain they’d love to have the chance to please me further, whoever they may be.”

She was only dimly conscious of the way Rainbow Dash stared at her longingly all the while, desperate, no doubt, to taste some of the wine herself. The poor thing, doubtlessly too terrified to think to just ask, but Nightmare Moon wasn’t just going to give it to her; she had to put forth her own effort. Just because she was now covered in so much luscious flesh, so many swollen curves, so soft and pliant and delectable, didn’t mean that she was no longer capable.

The alicorn was less aware of her penis coming loose from its confines, the dark shaft having slipped out from her thong and stiffened to life as it jutted out before her. When she did stop drinking long enough to look down at herself, she could only stare for several seconds as she attempted to rationalize the sensations of her own flesh, her cock and balls tingling with an excitement that the rest of her had yet to catch up with. The sudden erection wasn’t terribly unusual, though the feeling of swelling which coursed through her was more unusual, something which usually only transpired after ingesting very special drinks. “Oh, fuck,” she mumbled under her breath before taking another sip from the bottle.

And then, before her eyes, her straining dress split apart around the mass of her breasts, leaving the heavy mounds to hang free as they billowed outward, inflating with each intake of breath.

“Oh, ffffuuuuck.” Nightmare Moon cupped a palm against her skull. She genuinely didn’t know if she was starting to feel a buzz—it had been more than a millennium since the last time she drank enough to experience anything of the sort. She was definitely getting aroused, though, she could say that much without a shadow of a doubt. The sweet fire coursed through her, inflaming her senses and her erogenous zones, filling her with the desire to…well, she didn’t know what it was yet but there was certainly a lot of it.

“M-Mistress! Nightmare Moon!” Rainbow Dash’s voice came drifting to her, shouting from what seemed like the other side of a vast chasm even though they were right next to each other. “This can’t be right, that stuff has to be spiked! You need to stop so we can—!”

“Stop?!” She shouted, but it was fortunate for the pegasus that she was too unfocused to truly make a show of anger in the way that she typically would. Nightmare Moon staggered as she turned about and leveled herself in the direction of the shorter and yet broader mare, though that discrepancy in mass was in the process of growing smaller and smaller. The shadowy figure bore down upon Rainbow Dash with four huge black orbs, breasts steadily occluding her torso and balls hanging further and further past her knees, and a dark cock that bridged the gap between them. She didn’t put much care into the fact that this position meant the flared tip was prodding into the other mare’s stomach, but she didn’t particularly care (and, judging by her blush, Rainbow Dash might not have minded much either).

“What makes you think that…that we need to stop?!” Nightmare Moon bellowed, and she gestured to herself by clapping the half-empty wine bottle against her bosom. Then she threw her head back and laughed. Her starry mane rippled ethereally all around her, a swirling, inchoate nebula that was only loosely connected to her skull. “We can keep going for as long as we feel like! We are the ruler of this realm—our word is law! If we desire to drink this nectar every day, then we shall do so!”

Rainbow Dash struggled to come up with an appropriate response. She was having a hard enough time standing as the battering ram shaft continued to push against her, even without its owner taking any steps forward. The formidable length was like a tree trunk, throbbing veins running along its length, testicles now resting firmly upon the floor. The flare pushed up along the slope of the pegasus’s gut and into her breasts, the quivering urethral opening pointing toward her face, drooling with viscous fluid that was already staining her uniform. Her cheeks were flushing a deeper and deeper shade of red with every passing second. “B-but…” she cried plaintively, “you shouldn’t—!”

Nightmare Moon took another long swig of wine and her body ballooned again, another huge surge outward. Breasts and balls swelled into globes that supplanted the rest of her anatomy, except for the shaft which emerged from between the four of them. The tip shot out and pushed directly against Rainbow Dash’s face for a lewd approximation of a kiss. She might have protested louder if this motion hadn’t resulted in her muzzle being wedged directly into the gaping urethra. The heady stink of cum made her squirm, fighting with her internal urges to muster the motor controls to free herself. There was some terrible irony that she had been yearning for penetration, but this wasn’t the kind she imagined.

She pulled, but the opening around her muzzle was sealed shut, not budging an inch.

And then it pulled back on her.

Nightmare Moon kept drinking, not listening to the muffled cries of alarm, not paying heed to the tension that came from her shaft stretching and distending. She was already thoroughly inundated with sensory input from her overgrown frame. She didn’t have much need to think of anything being out of the ordinary when there was the distinct sensation of something passing through her, a mass that was steadily growing greater and greater as Rainbow Dash’s bottom-heavy frame was swallowed up, shoulders and then breasts and then belly and then enormous buttocks and thighs. She squirmed down into the alicorn’s innards, tumbling out and settling into her scrotum, more than doubling its volume as it stretched. It was just more swelling, in the end.

She couldn’t wait to do this again, just as she couldn’t wait for the explosive orgasm that was coming onto her.

Rarity looked down upon the alicorn lying in the bed. She was peaceful. She was serene. She was so unlike how she was during any of the times she was awake. The dark mare looked…almost innocent, the way she smiled, facial features twitching faintly every few seconds. Perhaps she was dreaming, enjoying herself (could she give herself good dreams?).

Less innocent was the penis which jutted up from beneath the covers, and which had just shuddered and vomited up a splash of cum, glistening white gobbets staining and seeping into the sheets.

“Every time,” she muttered to herself exasperatedly, shaking her head, “I hope Hearth’s Warming was worth sleeping in.”

Author's Note

(Note: Not all of the scenes written for this series were pony-related. If you would be interested in seeing those, check the updates on my FA page "nonsequitur".)

This ended up being written in the assumption that it takes place in the Onyx and Ivory canon, albeit with the caveat of all just a dream at the end since even this is a bit much for the usual fetishry of the setting.

The gifts are mostly vague in these but this one has more distinct implications regarding who the giver might be.

You can tell this is a dream because Rainbow Dash is acting way subbier.
