A Crown, Broken

The forever-present face of the moon shone down through high, arched windows and the delicately framed glass dome dominating the ceiling, flooding the bedchamber with eerie silver light. In the centre of the room, a bed like a quilted continent stood on a raised platform, the dark figure lying atop it bathing in the moon's glow as though it were a stage spotlight.

Even in sleep, it seemed that Nightmare Moon was a narcissist.

Chrysalis moved closer. She appeared to be clad in the purple armour of the Nightmare's personal guard, having adopted the blue skin and buzzcut rainbow mane of one of the Princess's favourites. Idiots. All a changeling needed in order to get to the Princess's inner sanctum were the words, 'You, there! Straighten up, or face Her wrath!'

All too easy.

Nightmare Moon had amassed quite an Empire since her return and victory over her vanished sister, and established her own palace deep in the Everfree. Now, it would all belong to Chrysalis. Dreaming up ways to humiliate the Nightmare once she was subdued had been very pleasant.

But first...

Moving quietly, making sure her hooves didn't make any sound as she crossed the polished marble floor, she approached the bed. Nightmare Moon was sprawled across it, beautifully naked. Her long limbs made her taller than Chrysalis's customary form, the changeling noted resentfully - she'd have to do something about that - her midnight-black skin flawless. Her eyes were closed; heavy breasts capped with pale blue nipples rose and fell slowly with her breathing. The ragged shroud of night that glowed around her body pulsed and flickered; strange, alien stars glowed within it.

"Relax, Princess..." Chrysalis whispered, in the rainbow mare's scratchy voice. "Your loyal guards are here to keep you safe. There's nothing to worry about at all..." For an instant, the outline of a twisted horn flickered where the guard mare had none, green light glittering in the air. "Sleep, my Princess... sleep deeply," she breathed, mind-warping power braided through her words.

Nightmare Moon stirred, inhaling more deeply before her breathing settled once more. A low, formless murmur escaped her lips.

"That's it... sleep. Relax. You're surrounded by your loyal guards... at the centre of your palace... nothing bad can happen here. You can just relax..." murmured Chrysalis, leaning over the softly-breathing alicorn. "Relax, your Highness..."

Of course, it stuck in her craw to address a pony in such a respectful way, but the words didn't matter. What mattered was the shimmering mist of emerald control that rode on them, settling over her victim as softly as gossamer. Little by little, creeping into her unconscious mind, warping it to Chrysalis's will. Nightmare Moon was merely the latest in a line of conquests that reached back through the ages, and if she was in any way special, it was merely in how much she could lay at the hooves of her new Mistress once she was properly shown her place.

Bending over the naked figure of the alicorn, Chrysalis eased her knee up onto the bed. Nightmare Moon shifted slightly, releasing a soft sigh, and her eyelids flickered. Slowly, her eyes opened.

"Look into my eyes..." hissed Chrysalis, meeting the Nightmare's unfocused gaze. Subtle green light swirled and danced mesmerisingly within her large pink eyes, her imitation of the rainbow-hued guard perfect in every detail. "Your most loyal guard, your favourite... you trust me... relax, my Princess... breathe deeply, and relax... you are safe, none can challenge you..."

"...none can challenge me..." Nightmare Moon agreed softly, in a far-away voice.

"That's right," Chrysalis reinforced. "Safe. Safe to relax, to let go, let it all go..."

Focused completely on Nightmare Moon's blank eyes, Chrysalis almost missed it, but her instincts were ancient and well-honed. Movement. Slow, subtle movement. "You are relaxed... sleep..." the changeling breathed as she carefully glanced down.

Nightmare Moon's hand had been empty before. Now it held a short, viciously sharp knife.

Chrysalis's gaze snapped back to the corrupted alicorn's face - and her heart jerked in her chest. Nightmare Moon's eyes were sharp and hard, slits of contemptuous malice, and her pointed fangs were bared in a smile that was almost a snarl.

"Foolish insect."

Chrysalis reacted with unnatural speed. Jerking backwards, her joints rotating through angles that no pony body could have sustained, she landed on her hooves in a tensed crouch. Green fire burned across her body, devouring the armoured vision of the Nightmare's guard to reveal the changeling's true form.

Slim, with small, flattened breasts and a tightly honed musculature, Chrysalis's ridged abs and toned limbs bespoke a body crafted for power and speed. Her skin was as black as that of her enemy, but while Nightmare Moon's body was the blue-black of deep space, her body was the reddish-brown blackness of caves deep beneath the earth. Strange, slanting holes pierced her limbs, and her nipples were an almost radioactive green, stark against the shadows of her body. A black crown rested atop her ragged, blue-green mane.

Rigid with hatred and frustrated rage, the Changeling Queen edged slowly towards the nearest of the high, arched windows, spitting, "Sso, the whimpering pony resorts to knives because she is too pathetic to possess talons."

"Hardly." Nightmare Moon swung her legs off the bed and stood up, a towering figure wreathed in a dark galaxy. Tossing the knife aside with a flick of her hand, she purred, "That was just to get your attention. Did you think, for an instant, you could trick me?"

"You mammals are all the same," hissed Chrysalis, circling the bed slowly, horn held ready. Sharp green claws at the tips of her fingers glittered in the silvery light. "You are soft, and you are weak. You will fall to me. You will offer up your Empire on your knees! Now, you're just going to get hurt first."

"You will regret those words," Nightmare Moon promised, her voice suddenly a whisper of ice. "I see through you, little insect. I see you creeping towards the windows, thinking that you can escape me." She flicked her ebony horn, eyes never leaving Chrysalis. A shimmer of light coated the walls and windows, flashing once, then dimming to a dull glow.

"No guards. No reinforcements. No help," Chrysalis snarled. "No pony to cuddle up to you and give you a big, warm hug to soothe your precious feelings. No witnesses. When I walk out of here wearing your form, not one of them will know what happened. Thank you, so much, for making this so easy!"

Green energy flooded up the malformed spiral of the changeling's horn, searing across the chamber in a virulent line of emerald fire. Shimmering blue energy surged out to meet it, wild and untamed, and a flaring burst of light exploded into being, etching actinic light and razor-edged shadows across the walls.

A low snarl of frustration bubbled from Chrysalis's throat, her eyes narrowed to slits against the glare of clashing power as she hunched forward, reaching deep and wrenching out everything she had to give; every last shred of hoarded, stolen love and natural power that seethed within her. Her skin burned with the intensity of the discharge, crawling shimmers of light crackling over her body that were almost lost in the radiance of their duelling magics. A whine filled the air, as reality itself strained under the burden.

"Is that all?!" Nightmare Moon demanded. A surge of explosive power flashed down the straining arc of magical discharges, overwhelming Chrysalis's magic like a tidal wave.

Before she could react, before she could think, Chrysalis was slammed back against the wall with crushing force, driving the wind out of her in an agonised gasp. Her crown clattered to the ground. The blinding light died. Nightmare Moon's hooves clacked across the floor, a darker shadow in the sudden dimness.

The Nightmare bent, and gripped Chrysalis by the throat. Her muscles flexing with effortless ease, the towering alicorn dragged her up onto her hooves, then lifted further, suspending her in the air. Chrysalis choked, her hooves struggling for purchase on nothing. Her body shimmered as she tried to change shape; Nightmare Moon squeezed harder, leaving her chest labouring as she desperately tried to draw breath despite the dark mare's crushing grasp around her throat. Black sparkles exploded behind the changeling's eyes as she was slammed against the wall once more.

"You dare try to challenge me in my own domain?" hissed Nightmare Moon, leaning in until her face was inches from Chrysalis's own. "I am the Mistress of Dreams! I rule the unconscious, and you thought you could entrap me there?"

Grabbing at Nightmare Moon's arm, Chrysalis struggled furiously, her wings buzzing against the wall as she tried to get enough room to use them properly. Her breath rasped in her throat, choked almost as much by rage as by the iron grip of the dark alicorn. "I will destroy your mind!" she hissed, with what little breath she could muster. "You will be a drooling shell for my drones to feast upon!" Scraping together her energy, Chrysalis poured all she could muster into her mind-warping magic, swirling green light blazing into being from her eyes. The eerie glow cast strange, shifting highlights across the Nightmare's face.

A glow which sputtered out as Nightmare Moon yanked Chrysalis forward, then slammed her into the wall again with bone-crushing force. "I think not. I am no weak-minded fool like my sister. There is not a creature in this castle that I have not bent to my will. You will be no exception." Chrysalis snarled, fangs bared, as Nightmare Moon leaned closer and growled, "Now you will look into my eyes."

Nightmare Moon's coldly glowing eyes filled the world. Her slit pupils widened, doorways into a deeper blackness, and to Chrysalis's infuriated shock, she felt a terrible pull from them, trying to draw her in. "You are wasting your time!" she hoarsely insisted.

"Sleep," intoned the voice of the Nightmare.

Exhaustion cascaded over Chrysalis, lead wrapping softly around her body. Her struggles grew weaker, the effort involved in even holding up her arms abruptly intolerable. Sheer fury pushed back, her chest filled with dull fire as she lifted a hand to claw the alicorn's eyes out.

Nightmare Moon caught her by the wrist. "You are weak. You are exhausted. You have used everything you had. Sleep."

"...I will destroy you," gasped Chrysalis, her wings buzzing, then drooping, then buzzing fitfully again. There was a roaring in her ears, a swelling blackness closing in from the edges of her vision. "Release me! I am your Queen!"

Black iron edged the Nightmare's words as she snarled contemptuously, "There is only one monarch in Equestria! Sleep!"

Chrysalis felt too heavy; everything was too heavy. Her body, which had always felt as light as a feather, was being dragged down to the earth. Her wings sagged. She scrabbled at Nightmare Moon's arm for a moment longer before her hand dropped heavily to her side; the other lay imprisoned in the dark alicorn's grip. Her head swayed, bobbing forward and snapping up as she fought the compulsion with all the rage of her offended dignity. "I rule-" she slurred.

Her eyes shut.

It should have cut off the sight of Nightmare Moon's eyes, but it didn't. Instead, they expanded to titanic size, leaving her a struggling mote floating in the glare of the Nightmare's glowing gaze.

And now, you have let me in, said a thought in her head that was not her own.

Chrysalis spun and twisted in the dark void, frantically lashing out. Nothing. Nothing she could reach, nothing she could touch. Searing bursts of green light flashed from her horn, diminishing into the endless blackness. Nightmare Moon's colossal eyes gazed at her with cold amusement, vast as worlds, as bleakly remote as the moon itself.

"You have no power over me! You're pathetic! A stupid, whimpering animal that spent a thousand years locked up on a shiny rock!" Chrysalis shrieked.

It is you that has no power here. Not anymore. Dreams, memories... the unconscious. My territory. Your mind is mine, now.

"Let me go!" screeched the changeling at the top of her voice.

She fell, the breath whooshing out of her as she thudded to the floor. The vision was over; Nightmare Moon stood over her in the silvery moonlight spilling through the bed chamber's crystal ceiling, gazing down with an expression of amused contempt that burned like acid against Chrysalis's pride.

"...kill you," the changeling promised in a breathy whisper as she rolled onto her hands and knees, wings extending.

"I think not," Nightmare Moon dismissively declared. "You are too weak to fight me."

A cold shudder ran through Chrysalis as she felt something change, deep in her mind. She could barely move; she felt as weak as a new-hatched drone. Covering it as best she could, Chrysalis forced herself up onto her hooves, claws extended warningly. "Foolish ponies shouldn't pick fights they can't win," she spat.

Nightmare Moon sat on the edge of the bed, giving a little laugh. Not the mad cackle of one pushed to the edge, but the pleasant sound of one catching a moderately amusing joke. "But they keep trying. As do uninvited insects." She gestured with her horn; all around the room, lanterns ignited, casting a brightening yellow-white light. "Come closer. I wish to see the clay I will sculpt."

Chrysalis's pupils narrowed sharply under the sudden illumination. She prowled closer; a lithe, dangerous figure, honed to athletic perfection, outstretched claws catching the light. "You're insane," she hissed, "as insane as your sister told all your ponies that you were." The words burned with venom.

Nightmare Moon's expression changed, shifting into a feral snarl. "Do not speak of that pony to me," she snapped. Then, after a moment, her sadistic smile re-emerged, and she added with more composure, "Not that it matters. You will share her fate. A mindless, eager slut that exists for the moments I condescend to fuck her."

"You dare-" Chrysalis began, shuddering with fury, but Nightmare Moon overrode her, speaking louder and more forcefully.

"She, however, is at least royalty. The commoners are unfit to abuse her, even when I have no use for her whining and pleading. The same will not be true for you."

"Perhaps it's her form I'll take, when I depose you. The monster is dead," Chrysalis hissed, circling slowly to one side. If only the stupid pony would let her guard down enough to lower the wards! "How the pitiful ponies will dance in the streets knowing that you have been cast down forever!"

"Enough." The word cut through the air like a razorblade. "You are unfit to even be useful as a brainless whore." She smiled darkly. "But that can be fixed. Let us begin."

An image flashed through the back of the changeling's mind, too quickly for her to fully register it. And then, to her utter shock, her body began to change. Sharp green energy shimmered over her small, flattened breasts, and they began to push outwards, a slow, steady expansion adding weight and heft to them, instant by instant.

"What-? Stop! Stop this!" Chrysalis snarled, grabbing at her own chest as though she could force her breasts to stop expanding. Instead, to her bewildered shock, pleasure exploded through her as she squeezed them, her legs trembling. Her acid-green nipples stiffened, widening as they jutted outwards, and soft, warm titflesh overflowed her hands. As violently as she struggled, she couldn't wrest control of herself, couldn't force her body to change the way she desired.

Finally, the shimmer of her own magic subsided. Massive, teardrop-shaped breasts jutted from her slim torso, making a mockery of her slender agility. Seizing one, then letting go as if burned by the renewed wave of pleasure that surged through her, she gasped, "How? How have you done this? Why?"

"You should listen more closely, insect." Nightmare Moon stood, stepping forward until she loomed over the shorter changeling. "Your unconscious mind is mine to command."

"Die for your impertinence!" screamed Chrysalis, raising her claws.

"Be silent," Nightmare Moon brusquely commanded. The back of her hand cracked against Chrysalis's huge tits, in a casual, open-handed smack.

"Nnnnh!" gasped the changeling, doubling over. The blow was like a bolt of electricity directly into her mind, leaving her staggered with the burst of pain/pleasure. Her thoughts fragmented, broken into shards by the pulse of need. Against her will, her pussy twitched, beginning to glisten damply.

"A good start. Though not nearly enough to make a bug like you fit for service."

Another image flashed into the back of Chrysalis's mind. A scream of unbridled rage broke from her as she jerked backwards, her new tits jiggling, but it made no difference. Her hard, toned body began to soften, her muscles losing their sculpted definition as they smoothed out into soft, strokable curves. Toned, slender thighs thickened, her hips widening as her ass filled out, growing rounder and rounder, giving her the pumped-up, obscene look of a sex doll.

"What have you done?!" Chrysalis shrieked. "I am the Queen! You can't do this to me!"

"You are a worthless slut," Nightmare Moon contradicted firmly, her fangs glittering as her generous lips parted in a vicious smile. "A stupid slut, too stupid to know when you were hopelessly outmatched. Too stupid to know when to hide in your filthy hole in the ground until I could be bothered to crush you. Certainly too stupid for a long name like 'Chrysalis'. I think Chrissy suits you much better."

A strange sensation shivered through Chrysalis, like somepony caressing the back of her neck. She took another step backwards out of Nightmare Moon's reach, teeth bared, blazing with rage as she felt her huge tits and over-inflated ass jiggle with every movement. "Chrissy will make you regret every word-" she spat, then stopped, her eyes widening. "Chrissy is Chrissy! Chrissy is the Slut of the Changelings! No! You stupid, evil bitch, Chrissy will destroy you! Destroy everything!" she howled.

"I have something far more suited to your new station to do instead," Nightmare Moon replied with savage calm. Standing up, she ran her fingers over her own midnight-black pussy, then held them up to reveal the way they glistened in the lamplight. "You have me quite worked up," she purred. "It's time you did something about it."

"Chrissy will burn your miserable castle to rubble and embers!" the changeling raged, trying to flourish her claws, only to find - to her abject disbelief - that they had been replaced by immaculately polished green fingernails.

Nightmare Moon didn't bother to reply. Instead, she caressed her bared pussy again. A sheen of dark blue magic flowed over her skin, collecting and brightening, extending outwards as a magical dildo formed, anchored firmly to her hips. The half-real toy was proportional to the Nightmare's imposing body, a lengthy, powerful shaft that glittered like her ragged mane, pulsing in time with the corrupt alicorn's heartbeat. Nightmare Moon caressed it, a shudder of pleasure visibly running through her. "Mmm. Sensation transference. Such clever little ponies under my thrall, coming up with new ways for me to fuck them." Her cruel eyes flicked up to Chrysalis's face. "Now. Isn't there something you need to ask me?"

It was Chrysalis's turn to have nothing to say. She backed up another step, her exaggerated ass pressing against the wall with a chill of cold against her hot skin. She couldn't look away from the enchanted dildo, her tongue flickering over her lips as she swallowed.

She needed it. She needed it! What was wrong with her?!

"You aren't allowed to touch me," Nightmare Moon said casually, seemingly reading her thoughts.

"Wh-what?" Chrysalis stammered, looking up at the taller mare before her gaze sank back to the shaft jutting from the Nightmare's hips.

"Not without begging, first."

"Chrissy would never beg!" Chrysalis spat. Nightmare Moon merely smiled, and crossed her arms over her own impressive, gravity-defying tits. The alicorn's body was incredible, with a wide, firm, perfectly rounded ass, a smooth, concave stomach, and heavy, jutting breasts. Long, smooth limbs, and delicate hands. The greatest body Chrysalis had ever witnessed, other than her own carefully-crafted handiwork. And that cock...

Her mouth was watering. Chrysalis licked her lips again. If she got close enough to Nightmare Moon, maybe she could lunge for the throat, disrupt her concentration. There was still a way to win. She just had to... lie, that's all, pretend enthusiasm like she had a thousand times before...

"...Chrissy wants it," she breathed.

"Pathetic. Try again."

"Please! Chrissy wants... wants your cock," she managed, choking down the acid of her pride. "Chrissy wants to touch it. Chrissy wants it!"

"You want to suck it?"

"Yes! Yes!" Chrysalis gasped, as the need inside her sharpened to a point. "Chrissy wants to suck your cock! Please! Chrissy is the best cock-sucker in Equestria, she'll make you feel so good!"

"I think not. Not the way you are. No, I will only let you anywhere near my cock-" Nightmare Moon ran her pale blue fingernails down the length of the glowing, semi-transparent shaft, "-if you beg me to keep improving you."

"You call this improving Chrissy?!" she demanded, jarred from her lustful trance. Even so, she couldn't fight the growing need at the back of her mind, and almost without realising, took a step closer. Her body was electrified with sensation, her skin prickling with need. One hand drifted up to her chest, and she squeezed her own breast, pinching the rock-hard nipple. A violent shudder wracked her as unquenchable pleasure eroded her will. "Do it! Please! Make Chrissy what you want," she begged.

It didn't actually matter what more the Nightmare did to her, did it? She was already a mockery of herself, transformed into an obscene fuckdoll! She just had to get close enough to take Nightmare Moon off guard, and then-!

"Better," Nightmare Moon replied, darkly satisfied. "Come, then."

Chrysalis lunged forward, dropping to her knees before the dark alicorn, reaching up to touch the other mare's shadowy, star-laden cock- and another change shivered through her. Her ragged mane smoothed out as it grew, spilling in wave upon wave of silky tresses down her back. A soft pressure pulsed through her black lips as they began to expand, slowly swelling to thick, cushioned fullness and taking on a glossy green colour that matched her nipples; perfect for pleasuring the dominant mare's cock.

The changeling couldn't bring herself to care. Turning her head upwards, she ran her forked tongue along the underside of the thick shaft, shivering with lust, then pushed herself higher to wrap her lips around the tip of Nightmare Moon's magical strap-on. "Nnmmm!" she groaned as she felt the heavy shaft tingle against her skin, lapping and slurping at the tip, teasing and tasting it. It felt so good! Her body was so hot!

An iron grip caught her by the back of her head. Before Chrysalis could react, even think, Nightmare Moon rammed the full length of her cock into the captured changeling's mouth and began brutally fucking her face. Chrysalis was jerked back and forth by the rough violence of it, every thought jarred out of her head, flashes of blinding white light exploding through her as every thrust felt as though it were grinding against her clit. Her arms fell limp to her sides, her eyes rolling up.

A hard slap to the side of her face jerked her back to awareness. She looked up, quivering as she struggled to breathe around the cock filling her throat, and met Nightmare Moon's gaze.

"Broken already, insect?" demanded the alicorn mockingly.

Fresh hatred surged through Chrysalis, raw and hot. Nopony looked down at her! No pitiful mammal, no pathetic, whimpering, colourful little bitch condescended to the Queen of the Changelings!

Then Nightmare Moon drew back her cock, and thrust forward, hilting it in Chrysalis's throat once again. The rage drowned in uncontrollable lust, her tongue twisting and lapping at the huge strap-on filling her mouth, one hand rising to pump up and down the shaft each time it pulled back from her lips whilst the other roughly mauled her titanic tits and ground against her dripping cunt. The Nightmare's cock felt as though it were fucking her mind, hammering her until she couldn't think straight. She was being broken, the iron grip of the alicorn's hand on the back of her head the only thing keeping her up as she surrendered, doll-like, to being used. Orgasm broke across her, pounding her insensible body, without relieving the unbearable pleasure/pressure that filled her to bursting.

An explosion of sensation flooded down her throat, a burst of magical fluids that filled her mouth and spilled over her chin. The grip that had anchored her helplessly in place vanished, and Chrysalis toppled backwards, as limp as a broken toy. Sucking in gulping breaths, the changeling managed to focus on the dark figure looming over her. Though half-obscured by the undersides of the Princess's heavy tits, the look of satiated pleasure on Nightmare Moon's face was insulting, and Chrysalis spat at her, hissing.

I am the Queen of all Changelings! I crush all enemies beneath my hoof! Ponies are my playthings, mine to control! Mine! I win! I always win!

"I will always be better than you," Chrysalis snarled as she levered herself up on one elbow, forcing herself not to use the insulting nickname with every ounce of her being. "You are the filth I scrape from my hoof! I am superior! I am perfect! I am the ultimate form of all life!"

Nightmare Moon's expression twisted, taking on a deeper contempt. She spoke, a low, forceful current to her voice that flowed directly into Chrysalis's mind. "You are a stupid slut."

"Chrissy is a stupid slut," Chrysalis echoed obediently, the words escaping her thick, pumped-up lips before she could control herself. The echoes rang around the inside of her mind, making it harder and harder to think of anything else. "No! Chrissy is..."

"You are a stupid, constantly-horny whore," Nightmare Moon declared forcefully, stepping forward to tower over the changeling. "You live to be fucked."

Chrysalis whimpered, shaking her head rapidly, then gasping as the sharp movement made her tender tits sway from side to side. She felt so hot, she was melting inside. Having Nightmare Moon's cock in her mouth just wasn't enough, she needed to be filled up with it! Wrenching her gaze away from the dimly glowing shaft, she gasped, "Chrissy is smart! Chrissy is destinated- destiny- desty- Chrissy is meant to rule! Chrissy will beat you!"

"Oh, you won't beat me, Chrysalis." Nightmare Moon crouched down, her ragged aura of stars swirling around them both and blocking out all else. "You don't want to. You love me. You want to please me above all else. You adore me. You are loyal only to me."

Never! NEVER! Chrysalis snarled wordless defiance, clinging to the core of hatred within her with all her might. Her horn sputtered with the dying dregs of her emerald magic as she desperately tried to ward off the Nightmare's influence, but there was nothing to push against. The tide of Nightmare Moon's power was already inside her head, tingling and pulsing, relentlessly pushing her back further and further. Her raw rage was being eroded, second by second, no matter how she tried to fan the flames, a terrifying feeling of dislocation coming over her as, for the first time in her existence, she was no longer certain that she was the most important entity in the world. Nightmare Moon's magic was... unstoppable, she couldn't stand against it...

Nightmare Moon had defeated her. Crushed her. She had to respect such power. Had to... had to serve such strength. Chrysalis shuddered as the last of her ego slipped from between her fingers, plunging into the seething ocean of magic drowning her very self. She had to... worship... to adore... The changeling's pupils widened as she gazed up into Nightmare Moon's eyes, a dizzying surge of new-born love blossoming in her chest like a brand new star. The alicorn was... so beautiful, so powerful...

Barely aware she was speaking, her voice hushed with reverence, Chrysalis whispered, "Chrissy loves you..."

"Very good," murmured Nightmare Moon, and Chrysalis felt a spike of sudden joy at the praise. A sadistic smile on her lips, the Nightmare continued, "You are my slave. You are my giggly bimbo fuckslave. You will take any shape I desire to please me."

Chrysalis nodded eagerly, a blissful smile on her face. It was so wonderful! She could be any shape her Mistress wanted! That had to mean she was special, even if she was a dumb whore! "Yes, Mistress! Chrissy is your dumb slut slave! Chrissy loves to obey you!"

Nightmare Moon - her glorious, beautiful, perfect owner - straightened. "Sit up. On your knees."

"Yes, Mistress, Chrissy obeys!" the changeling gasped eagerly, shoving herself upwards, only to overbalance and fall forwards, hitting the floor with her chin and crushing her huge breasts beneath her. "Oww," she murmured, then giggled and pushed herself up again. "Sorry, Mistress! Chrissy's big fat titties are heavy!"

Snorting a sound that could have been a laugh, Nightmare Moon gestured with her horn, and something floated from the floor up to her hand. Turning, she held it before Chrysalis's eyes.

A twisted black crown.

"What is this?" the Nightmare asked pleasantly.

Chrysalis blinked. "Uhh... is it Chrissy's crown? She had one like that, but-" she reached up and patted her head vaguely, "-she lost it. Oops. Sorry, Mistress!"

"Dumb bimbo sluts don't have crowns," Nightmare Moon explained in a cruelly amused, condescending tone. "Stupid sluts have collars. Isn't that what this should be? Fix it."

"Oohhh. Chrissy gets it!" Chrysalis chirruped, sitting up a little straighter and putting a finger against her bee-stung, cock-sucking lips. Reaching out, she touched the crown. It did feel familiar, like she'd shaped it before; the metal ran and shifted under her fingers, forming a black ring with a moon-shaped pendant dangling from the front.

"Good slut," Nightmare Moon breathed. "Wear it. Seal it shut."

Heart fluttering with joy, the ridiculously busty, wide-assed slave wrapped her former crown around her throat, and melded the opening in the ring together into an unbroken circle of metal. Cunt dripping, acid-green nipples jutting stiffly, Queen Chrysalis giggled with delight, declaring happily, "Chrissy is your slavecunt! Chrissy loves to obey!"

"On your hooves, you pathetic insect," commanded Nightmare Moon, straightening. "Pledge your loyalty to the one true ruler of this land!"

"Yes, Mistress, Chrissy obeys!" answered the brainwashed changeling brightly. Trying to stand, she found herself tottering to the side instead as she struggled for balance. Blinking, her large eyes blankly puzzled, she looked down at her hooves. They were no longer as she remembered them; the front of her hoof was intact, but the back had developed a long spur, echoing the kind of impractical stilettos once reserved for Canterlot parties. "Ooooh," she murmured, lifting one hoof to get a closer look, her wings buzzing to help maintain her balance. "Pretty..."

Nightmare Moon backhanded her across the face, the busty mare narrowing her eyes with impatience. "Your pledge."

"Oww!" Chrysalis whimpered. "Chrissy is sorry, Mistress!" Straightening up, finding herself the same height as Nightmare Moon now that she was balanced on her heel spikes and the tips of her hooves, she pressed both hands to her gigantic, wobbling tits and said earnestly, "Chrissy is, like, your total slave, Mistress! You're the hottest, and the strongest, and the tallest, and the most powerful, and, and Chrissy is this stupid slut, and Chrissy is so horny for you, all the time, Chrissy wants to suck your big magic cock and eat your pussy, and be your stupid fuckdoll, and be fucked any way you wanna fuck! Chrissy worships you, she, like, can't imagine not doing what you want! You're so strong! Chrissy is dripping just looking at you! Oh, please, can Chrissy suck your tits, or feel you up, you make Chrissy so horny just standing there-"

"A vast improvement in your attitude," Nightmare Moon cut her off, a savage light in her luminous eyes. "Perhaps the most satisfying improvement since my-"

She turned abruptly, without finishing her sentence. Stepping aside, the corrupt alicorn gestured at the bed with one hand, the other sliding lazily up and down the glowing outline of her ensorcelled strap-on. Beneath the hazy translucency of the spell, dark, shimmering wetness coated her hairless pussy and ran in droplets down her toned thighs. "Present your cunt for your Princess's use, slave!"

"Yes!" squealed Chrysalis, nodding rapidly. Tottering across the floor as quickly as she could, she bumped into the side of the magnificently carved bed and flopped forwards, planting her hands on the rumpled sheets and pushing her exaggerated ass into the air. Her tail twitched upwards, her silky, flowing hair flicking to the side like a curtain being drawn back to reveal her eager, dripping pussy. Her newly enhanced tits swayed between her arms, thick green nipples rubbing against the sheets and sending jerks of quivering sensation through her. "Fuck Chrissy! Fuck your bimbo whore with your amazing cock!"

Firm hands seized her hips in an iron grip, and the tingling shaft of the magical strap-on slid up and down her exposed pussy. Chrysalis gasped, a wave of dizziness overcoming her at the mere brush of the toy against her heated, throbbing sex; she had never been so sensitive before! "Ohhhh," she whimpered, pushing back against the toy eagerly, "Chrissy is so ready! You made Chrissy's body so perfect for fucking! Please, please, fu-"

In a single powerful thrust, Nightmare Moon slammed the shaft into her. Chrysalis cried out, back arching, a high-pitched wail of pleasure escaping her glossy green lips as the sensation electrified her spine. Over the hammering of her heart, she heard the glorious sound of her Mistress's laughter.

"How perfect," Nightmare Moon breathed, pulling back, then burying the magical construct into her newly-converted slave again with a shuddering gasp. "Every part of your body is reshaped for sex. Mouth, tits, pussy, ass... all of them sensitive enough to drive you out of your tiny mind. I will addict you to being fucked and used, and you will love every instant of it!"

"Yes! Yes, yes, yes," chanted Chrysalis deliriously, her jet-black body quivering with need. Every slap of the Nightmare's hips against her wide ass sent ripples through her tender flesh, every thrust of the thick toy breaking her thoughts into pieces. "Chrissy is fucking, Chrissy is addicted to Mistress's cock! Keep breaking Chrissy! Chrissy is a brainless fuckbug!"

"All changelings will serve me," hissed the alicorn, punctuating every word with a powerful thrust of her hips. "All must be broken, all must adore me! You will betray them to my control!"

Chrysalis was shoved forward by the force of the thrust, her nipples dragging against the bed sheets, her arms collapsing beneath her. For an instant, an image flashed before her eyes; her hive, filled with changelings coming and going from all Equestria, devouring love, manipulating, spying, controlling. A single vast web of devoted drones, all absolutely loyal to her, their Queen.

...she could give so many slaves to her Mistress! Mistress would be so happy with her!

Heart swelling with joy, her words broken up as her head jolted back and forth with each thrust into her yielding body, Queen Chrysalis gasped, "Chrissy wants you to - fuck and break - all of them! Dumb whoreslut Chrissy - will lure them - here! P-please, make all Chrissy's drones into - into your brainless cumsluts! Let Chrissy w-watch you - haaah! - watch your divine body as you f-fuck their brains out! Just like - just like you did to her!"

"That is what I desired to hear."

Nightmare Moon pulled back from Chrysalis. The changeling cried out as the shaft pulled out of her, breathing raggedly, her wings fluttering, hips jerking as her body instinctively sought out her Mistress's cock. A flare of magic tingled from behind her, a short, controlled burst, but even as she began to turn to look, the Nightmare's hands clamped down on her body once more and lifted.

Chrysalis squealed with surprise and delight as she was flipped onto her back, wings flattened beneath her. Craning her neck and looking up over the twin summits of her newly enhanced tits, she gasped eagerly as she saw that the shaft of Nightmare Moon's translucent, glittering strap-on had been joined by another magical dildo just below it. "Are you gonna fuck Chrissy's ass?!" she gasped, her eyes wide with joy. "All Chrissy's holes are for Mistress to enjoy!"

Nightmare Moon's gaze ran over the changeling's body, and she gave a short laugh. "Yes. Yes, they are." She glanced to one side, and her horn ignited, coruscating blue energy dancing over it. Chains slithered out from beneath the bed in a nimbus of magic, seeking out Chrysalis like single-minded serpents. Almost before the changeling could blink, the chains threaded themselves through the smooth, oval holes in her arms and legs and jerked taut, pulling her limbs widely apart.

Struggling just a little to show how hopelessly trapped she was, Chrysalis whimpered happily. "Chrissy is all chained down! Stupid bugslut can't move, or do anything!" Her gaze turned back to Nightmare Moon's body, taking in the heavy curves of the ebony mare with a shivery, eager hunger, and she added yearningly, "Stupid bimbo whore, chained down, ready to be used and fucked, all Chrissy is good for! Please fuck your dumb bimbo slut, Mistress!"

The tip of the magical strap-on grazed her cunt as Nightmare Moon pressed closer, and then, the other pressed against her ass. Chrysalis barely had time to register the dark alicorn's growl of lust before she thrust into her, mercilessly forceful. Brilliant light exploded behind the changeling's eyes as both shafts stretched her open, feeling as though she might break in two.

It felt better than anything she could have ever imagined, anything she'd ever dared to let herself feel before! Hers was now the body of a hopeless, helpless slut, a fuck-addicted whore that only existed for one thing. Chrysalis thoughtlessly pulled at her chains as she futilely tried to play with her own massive tits, each thrust forcing them to bounce and slap against each other; the twin shafts stretching open her pussy and hammering into her ass were breaking her, shattering her. As if in answer to her incoherent pleas, Nightmare Moon drew back her hand and delivered a stunning spank to Chrysalis's bare tits, the blow to her incredibly sensitive nipples sending a jolt through her that shook the entire bed.

"More!" Chrysalis gasped, wild-eyed. "Spank cumslut's giant tits! Mark Chrissy, fuck Chrissy, break your cumslut, break Chrissy!" she wailed, incoherent shrieks of unbearable pleasure ringing in her ears, her short, immaculately polished nails clawing desperately at the bed without gaining purchase. Sweat slicked her silken black body, her wings jerking and spasming beneath her. The sound of skin striking skin rang out in time with her cries as the corrupt alicorn's hips slapped against her rounded ass and thighs. Crushing orgasms pummelled her without cease, each peak barely fading before the next hammered her crumbling mind.

"...Chrissy's ass, fuck... fuck..." the changeling babbled, lost in the utter glorious pleasure of being fucked into oblivion by her Mistress, the only one that mattered, the only thing that could ever matter to her again-! A shifting, pulsing sensation flooded through her, and far beyond thinking, she begged incoherently, "Cum in Chrissy, cum, cum in Chrissy's ass, fill Chrissy, your cum, your perfect cum, obey, Chrissy obey, cumslut fuckbug obey!"

Her eyes rolled up, and darkness swallowed her.

-

Little by little, awareness slowly, sluggishly crept back to the changeling. For a long moment, she couldn't remember where she was, or what she was doing.

Her eyes opened a sliver, dazed and unseeing.

At first, everything seemed completely dark. Struggling for clarity, she forced herself to focus on her surroundings; the lamps were out, and she was no longer on the bed, but slumped back against the wall. The chains were gone. The silhouette of Nightmare Moon stood over her, a deeper darkness fringed with stars in the pale moonlight.

Recollection clicked into place. With a sudden, spasmodic jerk of her fingers, Chrysalis reached up to feel the collar that had once been a crown, iron hard around her neck. Her other questing hand found the massive curves of her breasts, jutting obscenely from her ebony body, and the mere brush of her fingers awakened an electric tingle of pleasure through her.

"Mistress!" she gasped, her chest filling up with heartbreakingly potent adoration and worship. "Thank you Mistress, thank you for fucking Chrissy, Chrissy loves you, Chrissy is yours forever, please fuck your dumb whore again!"

Nightmare Moon smiled with dark satisfaction, her fangs glinting in the silvery light, and reached down to pull Chrysalis to her hooves. "Of course you are mine forever. All ponies are. All Equestria is. You have found your true place, as will all of your verminous kind, soon enough."

"Yes, Mistress! All of them need to be your stupid whores, like Chrissy! Then you can fuck them all day- um, all night- as much as you wanna!" Chrysalis chirped. Wobbling a little on her stiletto hooves, she straightened up and gave a curtsey, idly sliding her fingers between her legs and rubbing the heel of her hand against her glistening pussy. "Mmmnh!" she whined eagerly. "Chrissy loves being fucked!"

Nightmare Moon gestured with her horn; a line of blue light swept over the walls and door, glittering as the wards disarmed themselves. Immediately, a heavy knocking became audible from outside the bedchamber door.

"You will be fucked," the dark alicorn promised, her pale eyes narrowed in malevolent amusement. "You shall be used by my guards, my servants, the commoners who grovel outside my halls... all of them. But first, there is one who you should begin by apologising to."

The ethereal glow of Nightmare Moon's magic touched the door handle. Immediately it burst inwards, an armoured mare throwing it wide and rushing in a few steps, sword drawn. Pink eyes darted from side to side, sweeping the room, and in a familiar scratchy voice, she said urgently, "Princess! I think there's an intruder in the castle, and your wards were armed! Are you safe?"

"Stand down," Nightmare Moon instructed dismissively. "Remove your helm."

"Yes, Princess," the guard answered more calmly, bowing her head low. Twisting her helm to the side, she separated it from her armour and tucked it under one arm, revealing the cyan skin and colourful close-trimmed mane of the Princess's guard captain.

"Ohh!" Chrysalis gasped, nodding. "It's the rainbow one! The one Chrissy was copying!"

"Yes," agreed Nightmare Moon, ignoring the brief flash of confusion on her guard's face. "Your impertinence must be punished." Her gaze shifted to the guard. "Captain Dash. Fuck this worthless insect."

Rainbow Dash saluted, her intense gaze snapping towards Chrysalis. "At once, Princess!"

Nightmare Moon smiled darkly as she settled on the side of her bed, watching with hungry eyes and lazily caressing her own cunt as the pegasus began stripping out of her armour. "Good. After all... the night is young."

Author's Note

This was the first commissioned piece I've done for a while, and I have to say I enjoyed it a lot. Working with these characters allowed me to go pretty dark, and explore things I hadn't yet reached in my published stories.

The piece was intended to be 2-4k words. At least it wasn't 17k this time...

Proofing, suggestions, and the actual commissioning by Equimorto.
