There are some unusual positions one must assume as head maid under Nightmare Moon.

In a different Equestria, Nightmare Moon won out over her sister and took her place on the throne. Life has adapted to this new, darker world in the time since then, ponies growing accustomed to their new ruler. One such pony, Rarity, formerly a mere seamstress, found herself taking on the role of head maid for the new royal palace, a job which she takes with the utmost of seriousness.

But Nightmare Moon has rather different demands for such a position than most would assume.

Contains the following: anthro, fat and hyper, intersex, sex, minor cum inflation and weight gain.

The Assignment

“Hey, Rarity.”

The unicorn made no attempt to acknowledge the smug voice, the rattling of armor as hooves came clopping closer. That wasn’t part of her assignment. She kept her attention focused upon the task at hand. These tapestries weren’t going to realign themselves, preferable though that might have been.

“Hey, marshmallow.” Just a few paces away. Rarity was sure that she was within reaching distance by now. “Don’t you know that you’re supposed to listen when an officer addresses you?”

“I know that I’m supposed to be doing my job,” she replied tersely. She felt the creasing of skin as she craned her neck upward, carefully examining the dark indigo tapestry, decorated with the moon and the stars, which hung from the wall, stretching into the shadows near the ceiling. The cyan aura of her magic dissipated once she was satisfied. “Oughtn’t you be doing your own job, lieutenant?” She spoke the title with biting denigration, as if she, a mere palace maid, could outrank a royal guard. “Is there not some hall you should be patrolling or a high tower you should be standing watch on?”

“There is, as a matter of fact.” The owner of the smug voice spoke assuredly, perhaps expecting this argument and having her rebuttal prepared, all the more confident in her position. “And it just so happens that my patrol brings me right past this fat ass of yours.”

The touch came then, as had been anticipated. Right upon her cutie mark, the slope of Rarity’s thigh. The fingers squeezed tightly, greedily, sizing up the thickness and pliancy of the broad slab of flesh. The aggressiveness of this motion made it seem like there was an attempt to elicit a reaction out of her, but she didn’t flinch in the slightest. That kind of rough play was like a foal weakly pawing at their mother. She only turned slowly to the side to finally address the other pony with an impassive, steely glare.

The armor of the night guard supplied those who were tasked with wearing it with a degree of anonymity. For her, it provided a subtle bolstering effect to her figure, making her sturdy-yet-lithe athletic frame appear a fair deal bulkier than it really was. It couldn’t fully obscure all of her sky-blue coat, though, or her violet eyes, or that confident grin which was so typical of her.

“You know that our Mistress does not appreciate sampling of her personal property,” Rarity said icily, the threat unspoken, like a concealed dagger. Though, at the same time, she made no attempt to shake the pegasus off either.

“Yeah, I know,” Rainbow Dash muttered, only half-listening, her gaze firmly drawn downward to the expanse of Rarity’s body. The expanse which occupied a significant span between the two of them. She leaned in closer and placed her other hand upon one of Rarity’s breasts, sinking into the doughy surface, kneading through the thin barrier of silken cloth that covered her skin. There was a yearning within her to pant and moan, a base instinct, but she had learned to suppress that a long time ago. That wasn’t part of her assignment.

“You must be aware, then, that the Mistress will be forced to punish you severely for this gross misconduct.” She said this matter-of-factly, no subtle pleasure at the idea of such, but certainly without regret as well.

“Oh, I’m very aware.” Rainbow Dash was pressing firmly against Rarity now, practically wading through her to get to the center of her mass. The armor was cold and firm against the unicorn, the antithesis to her warm flesh. Her eager grin now spoke to a different kind of lust, her eyes quivering with a manic, craving glee. “In fact, I’m looking forward to it.”

She pressed against the girth of Rarity’s midsection, reaching around her back to pull her into a kiss. Her lips and tongue lapped hungrily at her muzzle and her doughy cheeks, as if coaxing her to return the gesture. Her breath smelt more than a little of alcohol. More misdemeanors. She must have been desperately starved for attention today.

Rarity, for her part, could only sigh inwardly. For as physically strong as Rainbow Dash was, it took little effort for her to remain nearly still through all this, a rock in the midst of a raging hurricane. It only took the slightest motion, though, to produce ripples through her engorged figure, her exposed thighs and buttocks in particular wobbling profusely. This was going to put her behind schedule if it continued for too much longer, if nothing could happen to intervene with—

Rarity.

Her ear flicked. She hadn’t truly heard anything, though, over the pegasus’ slobbering kisses. The sound had been in her head.

Rainbow Dash found herself pushed away by Rarity’s magic, her feverish kissing and groping continuing for a few seconds before she realized what was happening. “Hey!” she shouted angrily, grabbing at the air between them, “Hey, marshmallow tits! What do you think you’re doing?!”

But Rarity wasn’t listening, her gaze turned to the side, to an unspecified point in the distance, through the walls of the grand hallway.

Your presence is required in the royal chambers.

She nodded silently, seemingly to nopony in particular.

Only after receiving that command did Rarity look back toward Rainbow Dash, and she promptly turned her nose up in the air. “My apologies, lieutenant, but I must be off, I have business of the utmost importance to attend to.”

“Utmost importance my ass!” Rainbow Dash snarled back, sparks crackling in her eyes, fighting back against the intangible forcefield between them. “You’re going to stay here until I’m done with you or else—”

There was a crack as suddenly the titanic mass of a white pony blinked out of existence right in front of her.

Rarity’s magic went with her, leaving Rainbow Dash to topple forward with a crashing clatter on the floor. She grunted and swore as she rubbed her nose. Her wings stood out stiff from her back. “We didn’t even get to the good part…”

= = = = =

Rarity momentarily felt the weightlessness of freefall before her hooves came to rest with a heavy thump upon the floor. Once again, a tremulous wobble shook through her form, but her expression remained as stern and stoic as before. She was used to this. This was very much a part of her assignment.

The Mistress usually had the decency to give her subordinates advance warning when she required something of them.

She did not, however, have the patience to wait for them to navigate the expansive halls of the castle to reach wherever she was waiting, especially a pony as encumbered as Rarity, so usually she would opt to teleport them directly to her.

The room the unicorn now found herself in was dark, only lit by a single ethereal blue candle on a table in front of her, casting long shadows over the walls. Her eyes would take a while longer to adjust to the gloom, but she was well-acquainted with the arrangements and the décor. Gothic furniture in blues and silvers and blacks stood against the walls, eerie twisted and curling shapes that in the low light appeared to be squat ghoulish figures, bowed in reverence. Further tapestries were hung around the perimeter, most of them depicting scenes of a dark pony standing over others—a white mare with a rainbow mane being a prominent recurring figure among them. Far in the shadows of the back of the room there was the shape of a sprawling bed, a low, hulking silhouette.

There was a mirror to the side in which Rarity could see her own reflection in profile—or, at least, a portion of it, as the glass surface wasn’t broad enough to fit her entirely. It would be difficult at a first glance to identify where the center of her mass was, where her skeletal structure began, buried as it was underneath vast acres of flesh. Her bosom jutted out farther in front of herself than the span of her arms, and the vast shelf of her thighs and buttocks did the same for the sides and rear. A ponderous gut hung from her midsection, past her waist and down to her knees, thick legs creasing against each other, swaddled in sleeves of flab, much like her arms, choking whatever musculature was underneath. She would have had a great deal of difficulty getting any work done if she didn’t have the assistance of magic. She wouldn’t allow anything of the sort to get in the way of her and her responsibilities, though, and she wouldn’t let her bulk diminish her professional demeanor. She wore a uniform tailor-made especially for her (the latest in a long line of attempts to keep up with her weight), a combination of a coat and a sort of leotard underneath that buttoned up over her front, regal enough to disregard that there was nothing over the broad slopes of her legs. Her purple mane and tail were tied up in buns, and the doughy plumpness of her face couldn’t entirely detract from the severity of her gaze.

Rarity took a great deal of pleasure in her appearance, not that she was likely to show much indication of it in public or even most private venues, as her reputation and position were of far greater importance. The ways in which she could use her appearance to further her reputation and position were the most important of all.

She turned her focus forward again, toward the one who had summoned her here.

The Mistress sat, watching her, on the other side of the table with the candle. It was difficult to properly identify her while Rarity’s eyes still adjusted to the gloom. Her mane stood out, a billowing cloud of blue dotted with stars, like a piece of the night sky, as did her eyes, icy circles with slitted, predatory pupils, and the thin crescent moon sliver of her smile. The rest of her body, though, was pitch black, and almost seemed to absorb what little light was around her. She had to be identified by her silhouette, an absence of space.

She was already naked. There wasn’t any point in maintaining formalities at this point (not that there was anypony who could have told her this was improper). She would frequently greet guests in this manner, just to see what their reaction would be. Rarity had seen this transpire many times, and there wasn’t much of a consistent pattern in which resulting action would be taken afterward. It depended more upon the Mistress’ mood at the time than how aroused or confused or disgusted the pony might be.

No words were exchanged for several long seconds. The dark mare seemed more than content to merely stare at Rarity, to drink in her shapeliness. The unicorn’s own body stood out strikingly in the low light, curves of gentle white reflecting the glow from the candle, cast in dull azure. She kept her hooves planted firmly upon the floor and held her arms clutched against the sides of her midsection, staring unflinchingly ahead, not speaking a word. She maintained this reaction even as the way the other pony was casually stroking herself became apparent, the indistinctness of her form resolving into the shape of arms clutching at her own body, one at the chest and one at the groin. She was making her lust clearly telegraphed.

Rarity was long since accustomed to all this.

“Are you hungry, Rarity?” Nightmare Moon asked, finally breaking the silence. In private, informal meetings such as these she tended to not be quite so exaggerated and dramatic in her speech, but she retained her noble tone. And she could never quite rid herself of the dark, demanding edge that hid in even the most basic and unassuming statements. She stopped teasing her nipple to tap one finger on the table. There was a bowl and a glass, filled with plums and dark, murky wine respectively, on the side closer to Rarity, which she couldn’t have been sure were there before or not, as if materialized out of the shadows.

“Yes, Mistress,” Rarity replied promptly. Not especially so, in truth, as she had eaten a filling lunch not long ago, but there was no point in splitting hairs over such details. Nightmare Moon would not have been satisfied with a meager and wishy-washy answer like that.

“Take a seat, then,” she said, gesturing to the empty space across from her.

“Thank you, Mistress.” The unicorn bowed, her chin pressing into the folds of her neck, her gut into her lap, before she stepped forward. There was no chair prepared for her, but again the routine she was accustomed to told her not to worry over such details. She stepped forward, her gait broad and straddled, grinding her legs together in the process, and, when she moved into position in front of the table, she simply leaned backward into a chair that manifested in place behind her. The “chair” was really more like a bench, as was necessary to accommodate her stupendous width, and her thighs still pressed into the wrought iron arm rests on the sides. Sitting down also wasn’t much different compared to standing, for as thick as the cushion of her rump was, keeping her raised.

Rarity was very aware as she levitated the bowl of plums to herself, over the expanse of breast meat that extended in front of her, that Nightmare Moon did few things without some ulterior motive that benefited herself. She wasn’t just offering food to her to demonstrate the hospitality of an employer to employee, ruler to subject, it was because she wanted to see her eat. Rarity was conscious of the piercing gaze upon her as she lifted one of the dark fruits to her muzzle, and she heard the subtle rubbing of flesh against flesh as she went back to masturbating. Well, Rarity wouldn’t be Rarity if she wasn’t determined to see her Mistress satisfied, so she’d be sure to make as much of a show of this as she could.

She bit into the first plum, tearing through the skin and into the moist innards, juices gushing in her mouth. She didn’t want to make a mess—not of her uniform, precious fabric as it was, or, worse, upon her pristine pale coat—but doing so paradoxically required loudly slurping up the juice so as to avoid any spilling from her lips, a predicament in which she couldn’t avoid seeming uncouth one way or another. The sweet fruit was gone in short order, and so she moved on to the next one, and the next one after that. In the gloom she couldn’t be sure that the bowl had any bottom. She could have used intermittent swigs from the wine glass to wash it down every now and then, but instead she waited until the very end, when she felt the taste of plums coating the insides of her mouth, to take the glass and drain it all in one long draught. The low groan of sexual satisfaction which came from the other side of the table told her that this gesture had been appreciated. There was a dull thump against the underside of the table.

“You eat so voraciously, dear Rarity,” Nightmare Moon crooned, licking her lips, “surely you can’t be satisfied with such a meager offering.”

“I am perhaps a touch more famished than I first estimated, Mistress,” she replied courteously. Her stomach wasn’t especially aching for further sustenance, but she was growing conscious of another yearning deeper within the core of her body, and that was what really mattered.

“Would you permit me to assist you directly, then?” That crescent smile gleamed in the candlelight.

“Of course, Mistress. I am always grateful for your generosity.”

“And I for yours.”

The two of them rose at the same time, though Rarity’s sluggish body made it so that she was a few seconds behind in this process, and as she stood to her full height Nightmare Moon was already stepping around the table. In motion it became easier to see the faint gleam cast upon her features by the candle, the sinewy tone underneath her skin and the flowing curvature of her frame. She possessed the kind of figure that alicorns were meant to have—tall, statuesque, strong, curvaceous. What she lacked in bulk compared to Rarity she more than made up for in height and in her raw, imposing presence. Her breasts and ass may not have been the size of beanbag chairs, but they were still pert and round and supple, more than large enough to overflow the grasp of her hands. That was to say nothing of the additional appendages which she possessed between her legs: a dark fleshy shaft which jutted from her loins, nearly straight outward, veins throbbing along its length, and an engorged sack that looked like a pair of watermelons, hanging to her knees. Rarity was well aware of all of this, intimately familiar with the dark mare’s proportions, just as much as her own.

But it was different here, in the near-total blackness of the royal bed chambers. The halls of the palace would typically be lit by braziers of eerie blue flame, and in here there was just the one candle. Darkness was Nightmare Moon’s domain, and in darkness she was stronger, her presence becoming all the more intense. Rarity knew that Nightmare Moon was approximately a head and a half taller than her, and yet she felt as if she had to crane her neck unreasonably in order to be able to meet eyes with her. The alicorn was a colossus, implausibly extending beyond the dimensions of this room, her mane and tail like the night sky itself, her cutie mark the moon, her great wings a canopy that could have covered all of Equestria. She could have smothered Rarity within the cavernous abyss of her cleavage. She could have squashed her underneath her monolithic cock and balls. She could have picked her up in one hand and devoured her whole.

But then Nightmare Moon leaned over and pressed against the unicorn’s marshmallow bulk. Her breasts were practically mosquito bites compared to her own. The flared cock head, jabbing against her stomach, was exactly as big as it was supposed to be. She grabbed at her flesh with ordinary hands, and that face staring hungrily back was no bigger than her own. The smell of night, cool and damp and earthy, came rolling off of her.

She pushed forward and planted their muzzles together. The kiss was eager and passionate, yet still gentle. This was still only the beginning, the appetizer, after all. Rarity, for her part, eased into the motions more than she had for Rainbow Dash, but she did not necessarily kiss back, nor did she reach to embrace her partner. It was Nightmare Moon’s place to take action, not hers, not until told otherwise.

Nightmare Moon broke away, though she didn’t retreat, rubbing along the length of the unicorn’s snout before pressing against her doughy cheek, nostrils flaring as she took in a great whiff of her perfumed scent. Her hands were probing all along Rarity’s bosom, sweeping in broad circular motions, squeezing the flesh. The prodding against her midsection was suddenly coupled with dampness, seeping through the fabric of her coat. That might have required heavy cleaning were it not for the likely possibility of this uniform being retired at the end of this night’s session.

The alicorn’s nuzzling reached higher, and she whispered into Rarity’s ear, “What have you seen tonight, my servant?”

Rarity needed a moment to recompose herself in the midst of the stimulation coursing through her. She took in a deep breath before responding, “Little of concern, Mistress. The guard has been more diligent since the demonstration with Stargazer last week. I did catch Shade Shield sleeping at his post. Suspect he’s let his sleep schedule fall out of order again.” After a pause she added, “And there was Rainbow Dash.”

Nightmare Moon groaned prematurely, and it wasn’t just because of her arousal this time.

“She made unwarranted advances on me despite my warnings as to what the consequences would inevitably be.” Rarity said this all with the utmost nonchalance. “I’m reasonably certain that she was drunk as well. She more or less admitted to me that she was trying to goad you on again.”

“Yes, I am aware,” she grumbled back irritably, “I picked that up as I was scrying for you. That Rainbow Dash is getting on my last nerve…” She squeezed and pushed harder with a slight buck of her hips. “If she weren’t so effective at combat I would have kicked her off the guard and banished her by now. She knows that I can’t afford to be rid of her.”

“Well…perhaps you should give her a reassignment, then.” Rarity whispered into her own ear now, and there was a sort of gossiping, mischievous undertone breaking through her professional demeanor. “If she’s so eager to be intimate with you, then let her be. And she’d be under my charge as well if that were the case; I’d be sure to whip her into shape for you.” There was a low chuckle in the depths of her throat, buried under the folds of her neck, as she let her hips sway from one side to the other.

Nightmare Moon went still as she hummed in thought. The sound was a low tectonic rumbling. They were so close together that they couldn’t truly see each other’s faces, but Rarity could still feel the muscles creasing in the dark mare’s cheek as she grinned wider than ever. “Yes…that sounds like it would be a more favorable outcome.” She giggled as her tongue slipped out to lap at Rarity’s face, pushing into the pliant surface. “And I’m sure it’s not motivated in the slightest by the way she treated you earlier.”

“Certainly not, Mistress,” Rarity replied, though she was grinning herself.

Nightmare Moon continued nuzzling her for a few seconds longer before she made the announcement of “That’s enough sampling. We need to bring out the main course.”

Rarity bit her lip unconsciously.

The alicorn pulled away, slowly dragging her arms along the breadth of the white mare’s chest in the process, toward the front. She paused briefly over the far ends, pushing into the spaces over the nipples. Then to the center, to the buttons. It would have been effortless for her to undress Rarity with her magic, to telekinetically undo each of the buttons and clasps until it fell away all at once, or to simply teleport the whole ensemble off of her. Both of them wanted to savor this moment, though, so instead she procedurally worked her way down the lapels of the coat and the leotard underneath, steadily exposing more and more of the pale-furred skin underneath. She had to heave up the tremendous globes in order to reach the buttons on the underside. She was starting to salivate at the sight of it all, cleavage pinching around the edges of the opening. Rarity was becoming more than a little hot and bothered herself as the anticipation built.

And then, all at once, it came spilling forth like an avalanche. The coat and leotard remained in place around her shoulders and thighs, but the flesh of her torso was fully exposed, gut sagging over her waist, breasts hanging over top, splayed slightly to the sides. The purple nipples, thick mounds with areoles like dinner plates, stiffened promptly upon meeting with the cool air. She gasped lightly at the feeling of the unbridled weight tugging on her body.

This seemed to momentarily distract Nightmare Moon, who took as much of each titanic tit as she could fit within the span of her arms and proceeded to bury herself between them. A low moan escaped from the depths between the two globes. Her cock was now pointing forward, under the lower curve of Rarity’s belly and down between her thighs, and she was lazily grinding against the burgeoning surfaces. Rarity’s legs trembled momentarily before she summoned her fortitude and calmed herself.

“Look at this.” The alicorn’s muffled voice came from within Rarity’s cleavage. Her hands stroked along the vast white-furred surfaces, fingers pressing deep into the skin. “Look at all this. Here is the scope of my domain. What a bounteous land for ponies. Celestia was too stringent to see anything like this. Luna was too meek. Only under my rule could such prosperity come to pass.”

“You have—” Rarity paused to wince as a pang in her loins beat upon the walls of her mental being. “—brought much to Equestria, Mistress.”

“But what more could I do for these ponies?” Nightmare Moon pressed closer until her flat stomach was flush with Rarity’s gut, their navels kissing. She remained buried within the embrace of mountainous white mammaries, but her hands moved to shed the mare’s clothing the rest of the way. The unicorn obliged by shifting her arms so that the sleeves could be tugged down along the swollen length of her arms. The coat fell away, but removing the leotard would be significantly more difficult, requiring pulling down over the far greater girth of her hips and thighs, shimmying down inch by inch until the curvature sloped back inward toward the knees. This much effort was already producing a thin veneer of sweat over both ponies.

After a tangible silence, Rarity sensed the unspoken desire for her to respond, so she asked, “What is your concern?”

When Nightmare Moon backed away, enough to allow her face to be visible again, there was a kind of wistfulness that had overcome her expression, even in the midst of her heaving, aroused panting, a far cry from the predatory intensity which normally pervaded her presence. “Ponies are such weak and fragile creatures. They can only be pushed so far with force before they break. It is becoming apparent to me that ruling with fear is only going to get me so far. If I am to remain in power, I must curry favor with them as much as possible.”

Rarity, for her part, still attempted to hold up a neutral countenance, while the fires inside her were stoked more and more, and now while she had to muster some attempt at cognizant thought. “Perhaps…you ought to work on a new image for yourself.”

Through the haze of lust, Nightmare Moon’s icy eyes were suddenly fixed pointedly upon her. A lesser pony might have fallen to their knees or fainted on the spot. Rarity was tougher than that, despite her soft shape. This was part of her assignment.

“Consider…a role of protector, rather than conqueror.” She gave a cursory glance at some of the tapestries around the room. “A monarch graciously protecting her ponies from the terrors of the night. They will gladly offer fealty to you if they understand that you are offering a concrete benefit for them.”

“Mmm…” Nightmare Moon began to slowly rock her hips again, pushing her shaft between Rarity’s legs, the tip coming tantalizingly close to her now bare groin. The thoughtful hum mixed in with the passionate growls in her throat. “What dangers, exactly, would you suggest we offer protection for?”

“Oh, all sorts of dangers, Mistress,” she replied, and she gave just a slight push back, adding to the pressure around the throbbing cock. “Roving packs of timberwolves ransacking cottages. Errant dragons razing fields. It needn’t take much coaxing to convince them. Small accidents, is all.” But there was a wry smirk at the corner of her mouth that suggested there would be no mere accidents involved.

The growls began to overpower the hums, a guttural grinding that rolled out of Nighmare Moon’s throat as her lips pulled back and bared her fangs. “Yes…now that sounds like a nightmare thing to do.”

Then she grabbed Rarity, seizing her around the midsection, and the unicorn gave a single sharp gasp as she was lifted from her hooves. Another magic-user might have struggled to raise her tonnage even with levitation, but Nightmare Moon did it entirely with her bare hands. At this moment, instinct kicked in, and Rarity in turn wrapped her own legs around the alicorn’s waist, just about smothering her in thigh meat, feeling the tensing musculature underneath the surface of her own burgeoning voluptuousness, and the length of her cock pulsated against her buttocks. Nightmare Moon’s hot breath wafted against her before she pressed her muzzle deep against her sternum buried between her breasts, now lapping with her tongue, fangs teasing at the ribs.

Nightmare Moon walked blindly, unwavering, managing to turn and navigate the room until she was able to put Rarity down on her back upon the bed at the far wall. There was one final brief moment where the two were separate, where Rarity could look up and over herself, between the mounds of her breasts splayed to the sides and the mound of her gut underneath, to Nightmare Moon standing over her. Her form seemed nearly completely black, only the faintest corona of candlelight around her edges, an eclipse shaped like a pony. Her jaws hung open, tongue lolling out, dripping saliva, her eyes wild, slit pupils slowly dilating.

That was the last reprieve. There was no attempt at slowly easing in when she bent over, taking hold of the white mare’s hips before plunging her whole length into the slit between her legs, past the flare and the medial ring all at once. Rarity bit her lip so hard that she nearly drew blood in her effort to hold back a scream. This was always the hardest part. Nightmare Moon was at her strongest in the dark, and in the depths of a pony’s womb the dark was absolute. Rarity knew that the cock was approximately three feet and ten inches in length and about eight inches in width when fully erect, and yet when it was inside her it felt like a siege engine, slamming at the inner walls of her body. The first thrust made her whole form wobble gelatinously, breasts rocking back and forth, thighs and buttocks rippling where the dark alicorn came to collide against her as she hilted. With the girth of her gut, though, the shape of the shaft that would have grossly distended her midsection otherwise was hardly noticeable.

Then the rutting began in earnest. The momentary ease of pressure as Nightmare Moon retracted herself returned and redoubled upon itself when she bucked her hips forward again, and then again, and again and again and again. Each was punctuated by a wet, meaty slap as their bodies collided, the alicorn’s flat stomach and firm thighs and full, bloated balls, swinging back and forth and adding their own secondary impact each time, and the unicorn’s strained groin and immense thighs and the underside of her gut. She cast a great shadow over Rarity, her wings fanned out to the sides, who in turn could only grip at the blankets of the bed she laid upon in an attempt to steady herself; even with her bulk, it felt as if she was going to be steadily pushed forward with each thrust.

She felt the pressure continue to build further as her innards began to fill. The walls of her womb, vagina and cervix and uterus overtaxed all at once, were being coated in their collective juices, cupfuls of pre already leaking from Nightmare Moon. Rarity knew that this was only the beginning, but there was nothing that she could do about it. She couldn’t have diverted from this path from the very start, but at this point there was absolutely nothing she could do but ride it out. She did her best to reciprocate the motions, to rock in time with the bucking of her partner, but with her size there was less that she could manage. The most significant thing she mustered was to clutch as tightly as she could around that fleshy shaft, to hold on for dear life.

“Rarity.” Nightmare Moon’s voice pierced the fog of pleasure that had consumed everything. She was terse and severe. “Tell me you love me.”

“Ah…oh…oh Moon…” Rarity panted and gasped, struggling to speak coherently as she tried to remember the practiced recitations, “how grateful we are for…for your—ngh!—silver moon…moonlight shining down upon this d-dark world, for…blessing us mere ponies with your kindness and generosity, so that we may—”

“No!” Her voice boomed in the closed chamber. The candle behind her guttered and flickered and nearly went out. The harsh noise was punctuated by another particularly forceful thrust, and Rarity briefly saw an indentation push through the surface of her stomach.

“W-wha-AH!” Rarity’s stammering broke out into a cry as the impact crashed into her. Something was wrong. This wasn’t part of the usual script. This wasn’t part of her assignment.

Nightmare Moon let go of Rarity’s hips and instead seized her by the nipples, squeezing each engorged purple teat in her hands. “Do you think I give two horse apples about that? I don’t want your fealty. I want your love. I want you to love me, Rarity, with all of your damned pony heart.”

“I…I…” Rarity felt like her brains were being scrambled. The pressure was building, arousal peaking toward climax, her body inflamed, her nerves coursing with electricity. Nightmare Moon stared down upon her expectantly, a stellar body ready to crash into the planet and obliterate all life if the answer was not satisfactory.

She had to grit her own teeth, force her eyes to focus, steel herself against the deluge of sensory overload. She had to remember who she was. Rarity, head maid to Nightmare Moon. Beautiful, tactful, professional. She couldn’t be cowed into defeat so easily.

Rarity fought to keep her vision straight as the pulsations rocking through her reached a fever pitch, and she looked back at Nightmare Moon unflinchingly, and she sneered as she muttered, “With you…f-f-fucking me like this…every night…it would be h-h-AH-ard for me not to l-love you…with all…my damn…heart…!”

Nightmare Moon groaned laboriously and trembled, her eyes rolling back in her head. “That’s…that’s what I want to…” She didn’t get to finish.

The alicorn’s voice gave way to a thunderous yell as her grip tightened and her body clenched, and she came. Rarity was already so stuffed that the cannonball blast of cum inside her was scarcely more of an addition, but that little bit was all that was needed to send her plunging over her tipping point. Her jaw hung open, letting out a long, low moan as her own innards squeezed and added further milky excess to the mix inside her. This was the only moment she could allow her façade of prim and proper obedience to fall away.

Nightmare Moon continued to thrust autonomously, driven entirely by impulse, each time adding another gush of semen to the flood inside Rarity’s body. As she continued to fill, the rippling and jiggling surface of her midsection shifted. The pliant surface grew rounder, tauter, the folds of flab along the sides smoothing out. Her navel went from a deep fleshy divot at the center of the mass to a shallow crevice. Before it had merely felt as if she was going to be torn open, now it felt like she would burst at the seams.

But the accumulation of stress slowly evened out and then stopped altogether, the surest sign that their orgasms were dying. Otherwise the two were too addled to be sure of much of anything. Nightmare Moon continued to buck incessantly for a few seconds longer before she stopped entirely, panting heavily as she leaned over the mare’s body. Rarity was limp; she probably would have collapsed entirely if she weren’t already lying upon the bed. Her vision was blurry, and when her senses returned to her she saw thin filaments of purple over her eyes, strands of hair that had come loose from her bun.

After a long pause which was only filled with the sounds of heavy breathing and gasping and groaning, Nightmare Moon finally unplugged herself from Rarity’s nethers. There was a wet pop as her slightly-less-erect cock came free, and it was only then, with the opening of the passage that had been crammed full for so long, that a splattering of white juices came pouring out, not that it would be easy to see against Rarity’s already white fur. With that over, she leaned over again and draped herself over the unicorn’s distended middle, spreading her arms wide and pressing her muzzle against the swollen surface, eliciting another incensed moan from her. This wasn’t the same as before, not hungry and lusting and greedy, a gentler embrace, slowly nuzzling while stroking in slow circles. Their individual warmth mingled and intensified.

“Thank you, Rarity.” Her voice now lacked the sternness of a tyrant, of one so feared as Nightmare Moon. “You performed admirably, as usual.”

“It is…my pleasure to…to serve…Mistress.” Rarity had greater difficulty finding the strength to move and to speak again. The astronomical weight of her body seemed all the more oppressive, especially over her stomach, smothering her innards.

“To love.” Nightmare Moon corrected for her. The weight only grew further as she then crawled on top of Rarity, pinning her down to the mattress. Rarity tried to groan, but Nightmare Moon pressed their muzzles together and they kissed—soft and yet insistent. It was almost pleading in the way she seemed to want the mare to kiss back. “Your service pales in comparison to your love.” There was something curious in her eyes. Wanting. Vulnerability.

“…Y-yes.” Rarity struggled to speak with the weight of the dark pony on top of her, crushing her. “For as long as…I am by your side…I will…I will love you.”

Nightmare Moon didn’t say anything else, but it seemed as if this had been enough to placate her. She leaned in to kiss again, delicately probing along the unicorn’s swollen curvature all the while. Rarity almost wondered if she was going to be used as a bed tonight, if this was to be some punishment for her.

Then she announced, “Ah, yes, allow me to fix this for you.” She then placed one hand against the side of Rarity’s overinflated gut, a tingling sensation spreading out from her fingers as her horn lit up with blue light. The magical power seeped into her, suffusing her body, and she felt the tension diminish ever so slightly as her womb shrank, the cum inside disappearing as it was absorbed directly into her flesh. There were perks to being consort to an alicorn princess, but that also came with some drawbacks. On the one hand, she didn’t have to worry about the complications of impregnation. On the other hand, all that seed had to go somewhere, and the fatty bulk of her body greedily drank it up.

The warmth spread all throughout her body as she briefly felt a faint strain within her skin as her mass increased. The space she occupied on the mattress expanded, extending just a few inches in every direction. She felt her breasts creeping across her arms and her thighs pushing tighter against each other. Her stomach returned to its flabby consistency but did not shrink to nearly the same size it had been prior. Before her very eyes she saw her cheeks plump up further, taking up just a little bit more of her field of view, as her neck and arms and legs thickened, inhibiting their dexterity further than ever. A few dozen pounds, she would have to imagine, and she idly wondered how much newfound difficulty she would have when she eventually had to stand up again.

“There. Now we can…rest…” It seemed like Nightmare Moon was already well on her way to slumber, her eyelids intermittently fluttering, steadily lower and lower. Not before she shifted to the side, and she reached around to Rarity’s back, pulling with her so that she turned onto her side, the two of them gazing into each other’s eyes, one nestled within the other’s cleavage. Nightmare Moon’s starry ephemeral mane billowed faintly as it rested over the swell of the breast she was now using as a pillow, and she moved so that their horns knocked together. “Sleep well, Rarity…you’ve earned it.”

“Thank you, Mistress,” Rarity replied dutifully, wearily.

Nightmare Moon moved for another kiss, her eyes closed, and in the middle of that she fell asleep.

Rarity did not fall asleep, not yet. It was hard for exhaustion to take its toll upon her while her head was abuzz with thought about everything that had been said tonight.

Love? Nightmare Moon wanted to be loved?

It was an idea that seemed antithetical to the image that she had built for herself ever since her return and the overthrowing of Celestia. Her rule had been stern and cruel, cracking down on the slightest hint of wavering loyalty in any of her subjects. Her staff had been encouraged to do the same, Rarity included. What could have changed?

In slumber, the dark alicorn didn’t seem to bear any of that enmity, as calm and serene as any sleeping pony. And, even in the dark, she was held in stark contrast to the overflowing immensity of Rarity’s body, despite her own powerful build and voluptuous curves and still faintly throbbing cock. It wouldn’t have taken much to reposition her breasts enough to smother her in her sleep and rid the world of the danger she posed.

Rarity wouldn’t do that. She was too used to the idea of ensuring her Mistress’ pleasure and enjoyment and satisfaction to knowingly bring harm to her.

Rarity would always be loyal to Nightmare Moon.

But for Rarity to truly and sincerely love her?

That she wasn’t so sure of. It would take a great deal of effort to recondition herself to that kind of mentality again.

Perhaps more effort than it would take to convince Equestria and the world at large that Nightmare Moon could be a force they should welcome in their lives.

Or more effort than it would take to coerce Rainbow Dash to be a productive part of the castle’s maid retinue.

Rarity would try to do it all the same, that was just a part of her dedication to her Mistress.

She made a mental note to add it to her assignment, alongside the reminder that she would need to take her measurements for another new uniform, and only then did she allow herself to go to sleep.

Author's Note

I was inspired by an apparent lack of night maid Rarity fetish content to fill that void. Only five years late to the party.

There was debate on whether Rarity or Nightmare Moon would be the cock-haver in the relationship, and that would have changed the dynamic significantly, but I suppose I came to the decision that the Rarity version I had in mind would have required more explanations so I decided to just have it be the standard domineering ruler NMM route.

Some inspiration comes from the court politics of The Favourite.
