The doors to the throne room flew open, nearly breaking off their hinges. Luna stepped inside, purpose in her eyes, her sandals clacking against the stonework. Her clothes were dirty and torn.

A day had passed since Sombra had marched on Canterlot, and he hadn't left the palace unguarded. She'd had to fight against her own subjects—even some of her own guards—to make it here.

But even two platoons of soldiers wasn't enough for the power of an angry alicorn.

Celestia had remained at the castle, and she'd heard nothing from her. The Element bearers had gone ahead... and she'd heard nothing. Something was wrong, and she and Starswirl had both known it. He could tend to the forest on his own. She needed to be here.

She looked around as she entered. She'd expected to find Sombra here, seated on one of the thrones, ready to gloat at her. Perhaps her sister and the Elements of Harmony would be there, chained and muzzled as trophies. The stallion was certainly vain enough to try it.

But the throne room was empty and unlit. There weren't even any guards.

So obviously it was a trap.

"Show yourself, Sombra!" she demanded, her command echoing off the walls.

As if in response, the doors slammed shut behind her, sealing her inside.

Definitely a trap then. Well, that was fine with her.

"Coward!" she roared. "Come out here and face m—"

Twin beams of magic lashed out at her from the shadows of the rafters. She spun about, threw up a shield—but she wasn't fast enough, and the magic that assaulted her hastily-erected barrier was overwhelmingly strong. It broke through after only an instant.

She leapt out of the way as the beams bit into the stonework, firing back one of her own. She saw a flash of white feathers, a glint of something metal, but they darted out of the way too quickly for her to get a good look.

Something was up there. Snarling, Luna launched her own shotgun-blast of a magic volley, multiple bursts of magical energy in an arcing pattern that burst as they hit the ceiling.

"Reveal yourself, fiend!" she shouted up, readying a second. She could hear them moving, whoever or whatever they were, up in the rafters where the shadows were long.

Another blast of magic lanced out at her from the side. She swiftly dodged it, turning to face her assailant. The power she had been charging up unleashed itself, a bright spear of moonlight that blew away the darkness as it passed.

There her opponent was. Now revealed, the armored figure dove towards her, horn charging. Another brainwashed guard... but this was different from the ones outside. This one wore a uniform, with a differently-shaped helmet, and had wings... and a horn? How could that...

Luna faltered as she recognized who it was under that visor.

"...T-Twilight?"

That single moment of hesitation was her undoing.

She heard the quiet thud of something landing behind her just a fraction of a moment too soon to react. Something swept her feet out from under her, and she grit her teeth as she hit the ground.

Before she could recover, she felt something in her horn. She glanced up. Black crystals had sprouted from its base, nullifying her magic.

In that one instant, she'd already lost.

Magic took hold of her limbs before she had the chance to get her bearings, lifting her up into the air. Golden-yellow magic took hold of her right wrist and ankle; bright magenta magic wrapped around her left. She strained against it, but to no avail. Whoever or whatever it was that was casting it was just too powerful.

The armored mare—Twilight landed gently before her. She had the posture of a soldier, and now that Luna had the chance to properly observe it, the armor she wore was bizarre. What she had originally assumed to be a full body of plate armour was, instead, a set of smaller, more decorative plates, and...

Was that latex?

Whatever it was, just looking at it set off alarm bells in Luna's mind. There was something wrong about this armor. And not just the way it covered almost every aspect of the pony who had once been her savior.

"Twilgiht," Luna said. "What are you doing? What is that thing?"

Twilgiht made no move to answer. Instead, the pony behind her began to move, their footsteps echoing through the chamber. As they did, the sconces that lined the walls lit, one by one, bathing the dim room in light.

The figure crossed into Luna's field of view...

And she wasn't wearing a helmet.

"No," Luna gasped, as her eyes locked with the twin pits of green and purple smoke that had taken over her sister's.

"Hello, sister dearest," Celestia said, but there was no warmth in the words. Her voice was cruel, twisted, a mockery of her formerly gentle tone. "I've missed you ever so much..."

"C-Celestia?" Luna stammered. "What has he done to you?"

Celestia looked at her sternly. "Now, sister. That's no way to address your king."

"Sombra... Where is he?" Luna demanded. "Where is King Sombra!?"

"Our king is supervising the expansion of his kingdom," Twilight said.

"But don't worry, Luna," Celestia said. "He left the two of us behind in his place, just for you."

"To do what?" Luna spat. "Imprison me? Execute me? You'd never."

"No, sister" Celestia said. "You're far too useful to our king for that."

The magic posed her, arms fully outstretched to either side, legs slightly apart.

"Instead, you will serve him."

A flash of yellow, and a set of armor appeared in the air beside her. This armor was different from the ones worn by Celestia and Twilight. It was lighter, more elegantly sculpted, and made of a darker metal.

It also lacked a helmet.

"You have been chosen to become our king's knight-assassin," Celestia said. "Rejoice, and embrace your role as his servant."

She took part of the set in her hand, held it so Luna could see. A metal mask, smooth and devoid of any features except for a pair of open eye-holes and a pair of openings to accommodate the nostrils. No mouth.

"Take a good, long look, sister," Celestia said. "Soon, this face will be yours."

"Sister, please!" Luna begged. "You must fight his influence!"

Celestia laughed as she approached, the mask floating away and another piece taking its place—a vambrace, to go on her forearm. "Why would I fight it? His will is my will. His pleasure is... mnn... my pleasure."

Her hips rocked together in time with the groan.

She came closer, gingerly holding the vambrace, and Luna's eyes followed it as it came closer, closer—

"Please, Knight-Commander," Twilight said, suddenly. "Forgive my insubordination. May I have the honor of dressing her?"

Celestia raised an eyebrow, not looking back at Twilight but from her peripherals. She considered it, relishing as her subordinate squirmed behind her. On the one hand, making such demands was unbefitting of a Knight. On the other...

She'd get to watch as her conquest took her sister.

Celestia licked her lips. "Request granted, Knight. Put on a good show for me."

Twilight's posture relaxed slightly. "Thank you, Knight-Commander."

The subordinate stepped forward, and the commander stepped back. The vambrace was passed from one to the other, slipping from Celestia's magic and into Twilight's waiting hands.

Twilight's horn lit, and her helmet was removed, giving Luna a full view of the face of the mare who had once been her savior, and those deep, green holes where once there had been beautiful lavender eyes.

"Twilight," Luna gasped. "Don't do this. You are a princess of Equestria! The Element of Magic!"

"I am my King's servant," Twilight said, stepping closer, the pieces of armor, now aglow with magenta instead of her sister's gold, floating along behind her. "His will is my will. And soon, you will serve him, too."

Twilight's horn glowed. One piece at a time, Luna's clothes were ripped from her body, first her dress, then her jewelry, her sandals, her undergarments. The small black crown on her head was taken last, cast aside like a piece of common trash, sending it bouncing across the castle floor.

Luna, naked, thrashed against her magical bonds to no avail as Twilight came closer, closer...

Twilight stopped, so close that Luna could hear her breathing, see the slow expansion of her chest. The outfit Sombra had put her in didn't leave anything to the imagination— if anything, the latex extenuated her curves, the metal breastplate pushing her bust up and out...

If Luna hadn't been so terrified, she might have been turned on.

She wrenched her eyes away from Twilight's chest and fixed her gaze on her captor's face.

"Twilight Sparkle, listen to me," she said. "You're stronger than him. You have vanquished him in the past, and you can do it again, I know you can. You must fight his influence. You must res—"

Twilight placed a single latex-clad finger over Luna's lips.

"Shh," she said. "There is no reason to resist. Resistance brings nothing but pain. Only through complete devotion to the King will you experience true...."

Her voice turned husky on the last word.

"...pleasure."

Her hand withdrew, and she moved over to Luna's right arm, held straight out from her side at the wrist.

"You're going to love being King Sombra's loyal knight," she said. "I promise."

With that, she brought the vambrace up and held it against Luna's forearm. The dark, cold metal almost made her shiver.

Working slowly, gingerly, she wound the leather straps of the armor piece around, threading each through its respective buckle. She used her hands, not her magic, and the gentle brushes of her gloved hands and Luna's arm brought a strange heat into her cheeks.

Twilight wrapped her fingers around Luna's wrist and braced her arm as the first of the straps was pulled tight.

"Twilight, please," Luna begged.

Twilight just smiled, as she slowly, so slowly, pulled the second strap into place...

As the vambrace was pulled against her skin, she felt something in the plates begin to move.

As she watched, eyes widening, the grey substance that covered Twilight's and her sister's bodies began to spread across her own.

She squirmed and grit her teeth as it spread out from under the metal, inching first around and then down her forearm. Everywhere it touched began to prickle and heat up, the sensation of the material moving over it suddenly becoming ten times what it had been at first.

"Our king's magic is generous," Twilight said, as the latex slid down Luna's fingertips, making her shudder. "Your body will be encased beneath his will, and you will experience fully the pleasure of total servitude to him."

That explained the heat building in her cheeks.

Luna swallowed as the movement stopped, her arm encased fully up to her elbow in Sombra's gray. She'd worn latex before—she'd experimented quite a bit, upon her return from the moon, and the rubbery substance had been one of her favorites, but this was different.

Her own latex gloves had never felt this good.

Twilight walked around behind her, out of Luna's view. Luna looked up at Celestia, who was watching closely... and smirking, one rubbery finger pressed between her lips.

"Sister, you have to remember!" Luna said. "One thousand years ago—we fought through Sombra's enslaved legions together! We confronted him at the top of his palace, and we banished him beneath the ice of the Frozen North for his crimes against the Crystal Empire!"

"Remember?" Celestia said, lowering her hand. Her smirk remained. "Of course I remember, sister."

"Then—"

"I remember what fools we were."

Luna cut off, mid sentence, her lips parted still but no sound coming out.

Celestia laughed. "Defying King Sombra was pointless. I should have thrown myself at his feet then, instead of having to wait a thousand more years for him to show me my place. I am fortunate our king was so generous as to give me a second chance to serve under his brilliance, to remake me into his loyal Knight-Commander. To show me the ultimate pleasure: submission to his will."

Luna just stared at her sister, open-mouthed, as the hope drained from her eyes.

"And now," Celestia said, as the next plate pressed itself into Luna's left forearm from behind. "It is your turn to be remade, sister."

Twilight, still out of Luna's view, pulled the straps tight. The latex began spreading, a mirror to what had happened only moments ago on her other arm. Soon, both forearms had been encased in rubber.

Her tormentor stepped around to her side, fingers intertwining with Luna's own freshly-covered ones, the latex of their gloves squeaking together. Twilight leaned forwards and took the ends of Luna's fingers in her mouth, sucking on them and running her tongue across their tips.

Luna bit back a groan at the seductive gesture. She could feel her nethers beginning to dampen, unbidden.

Twilight pulled back. She stepped around to Luna's front, putting her back in full view of her prisoner.

"What piece should I apply next, Knight-Commander?"

Celestia tapped her chin. "Hm... The greaves."

"Yes, Knight-Commander."

Another piece of armor floated into Twilight's hand. She knelt (bringing her head and the tip of her horn oh-so-close to Luna's dampening folds) and began to strap it to Luna's left calf. The buckles bit tight into her muscle as the latex began to spread, but just as quickly Twilight took hold of the other greave and strapped it into place on her other leg.

Luna bit into her lip as Sombra's magic spread down, across her calves and her ankles. It slipped over her heels and down the soles of her feet, slowly forming into a pair of soft-soled boots. Even as she tried to resist, however, Twilight distracted her with a trail of kisses up the inside of her right thigh. She got so close that Luna could feel her warm breaths against her folds as the latex completed its work and she drew away.

"The cuisse, next," Celestia said. "I want to watch her squirm."

Twilight smiled.

"Yes, Knight-Commander."

She remained on her knees, between Luna's restrained legs, and retrieved two more plates from the floating collection of armor, which was growing smaller and smaller with each passing minute.

Luna eyed the mask wearily. She was running out of time.

If she could interrupt Sombra's hold over Twilight, then maybe...

"Applejack," she said. "Rarity. Pinkie Pie. Fluttershy."

Was she wrong, or had Twilight hesitated, just for a moment?

"Rainbow Dash," she continued. "Cadance. Shining—"

She gasped, as the cold metal pressed against her thigh, and the straps wound across her inner walls.

"S-Shining Armor. Spike. Starlight Glimmer. Twilight Velvet. Night Light." She had to be getting through. She just had to. "Don't those names mean anything to you, Twilight Sparkle?"

Twilight paused. Luna's heart did a flip.

"Remember them, Twilight!" she insisted. "Remember who they are!"

"I remember," Twilight said, slowly.

Luna cheered inside. "Then—"

"They are all servants of King Sombra," she said. "As am I."

Despair filled Luna as Twilight pulled the second strap on the cuisse tight, eliciting another short gasp from her captive. This turned into a moan, quickly bitten back but still very, frighteningly real, as the latex began its march down her leg.

Luna's leg twitched as the cold material crossed the inside of her thigh. This wasn't helped as Twilight slid her finger up along it, making a trail through the semi-solid gray and helping it spread upwards, stopping just barely an inch from her crotch. There was no hiding her wetness now.

Twilight moved to the other leg, repeated the process. This time, Luna couldn't stop the moan that escaped her lips.

"It sounds as though you're finally beginning to enjoy yourself, sister," Celestia said, and Luna could just hear the smirk in her voice.

"Not... fair..." she panted out, as Sombra's gray permanently eclipsed her moon.

Both legs were now coated in solid gray from the hip down. The heat building in her was intense, and her cheeks were brightly flushed.

Get a grip, Luna, she told herself. You just have to endure until an opportunity presents itself. Just... endure...

Her thought trailed off as Twilight began to stand, trailing her fingers up along her insanely sensitive latex-covered thigh and—

Luna shuddered as Twilight's finger slid along her lips and brushed, just briefly, over her clit.

"Nnngh..."

"The shoulders now, Knight-Commander?"

"Excellent idea, Knight."

They floated over. These differed in design from the ones that adorned Twilight and her sister; they were more rounded, less bulky. Clearly designed for lightness and freedom of movement, rather than intimidation.

They fit onto her shoulders perfectly. Twilight leaned in as she strapped them down, the cold front of her breastplate pressing into Luna's own bust. She grit her teeth, tried to take her mind far, far away from what was happening.

The latex began to spread across Luna's collar and down her arms.

"I saw those looks you gave me." Twilight whispered.

And just like that, Luna was wrenched back to the present, even as the rubber merged with that on her forearms.

"W-what?"

It dripped down, just over the top of her breasts, and somehow that was worse.

Twilight pushed forwards, pressed herself into Luna, forcing her breasts forwards, and as heated up as she was, Luna couldn't help but look...

"Give in to it," Twilight said. "Embrace your new life as our King's servant. Embrace your place at his feet. Embrace the pleasure."

She drew back, and part of Luna was sad to see her move away.

The rest of her, the part that wasn't taken over by need, began to panic.

"Forever..."

"Nnn... no," Luna said.

Twilight didn't ask for the next piece. Whether Celestia minded, she made no indication.

The collar was plucked from the air, unlatched and pulled open. Twilight placed her hand under Luna's chin, forced her head up. Luna tried to resist, but magic took hold of her temples and there was nothing more she could do.

The collar fit into place snugly around her throat. Twilight latched it shut, then released her head, not that it made much difference; though it seemed to offer more flexibility than those worn by Twilight and her sister, it still forced her head up and forward.

That wasn't the only difference, though.

As the latex crept down between her wing joints, she felt something else begin to move behind her. With the limited mobility afforded by the collar, she could only barely see as a cloak unfurled over her shoulders and behind her, falling over her wings and stopping just shy of the ground. It was pitch black, matching the metal of her armor, and light as a feather. Judging by the weight around her shoulders, there was a hood component, too.

"That's... nnn... new," she managed to wisecrack, somehow, even as the latex crept down, stopping just at the top of her bosom. Perhaps it was one last-ditch effort to hold herself together.

"You are a Knight-Assassin," Celestia told her. "A creature of shadows. Executor of your king's will. Your king saw fit to give you an armor better suited for your purpose. Be grateful for his generosity."

There were only two pieces of armor left. The breastplate... and the mask.

Twilight took the breastplate. She did not take it in her hands, however, as she had every other piece; instead, it remained floating in her magic.

She trailed a finger down Luna's bare front, starting at her collar, running down between her breasts and across her stomach. Part of Luna wanted her to keep going, to reach her puffy, neglected clit and her wet, dripping folds, but Twilight's finger pulled away just fractions of an inch too soon.

Luna's breaths were haggard, now. Her pussy ached, and long strands of marecum dripped out of it, pooling below her on the stonework. What parts of her still remained bare were soaked with sweat. Her ethereal mane billowed out behind her, agitated.

"You're going to love this, Luna," Twilight said. "It's what broke me."

Luna steeled herself. She knew what would be coming.

But once again, Twilight did something unexpected.

She slid down to her knees.

Her face crept agonizingly close to Luna's snatch. Each warm breath heated her puffy folds, made them ache harder, demand release. Her hands grabbed two fistfuls of Luna's ass, squeezing them.

At the same time, the breastplate levitated over, floated just in front of Luna.

"N-no," she begged. "Twilight, please, you can't—"

Twilight's tongue slipped between her folds just as the breastplate pressed itself against her skin.

"AHAaaaah," Luna half cried, half moaned. The twin molded cups slid under her breasts, raising them and propping them outward. It conformed to her curves perfectly.

Twilight's tongue danced around inside her, seeming to find every perfect spot as the straps on the breastplate tightened, pulling it tighter around her chest, pressing her sensitive nipples into the cold steel.

And then the armor's magic activated.

Luna threw her head back as the rubber spread across her breasts. She strained against the magic holding her in place, shuddering and twitching, but all that served to do was amplify the insane pleasure as her perked nipples ground into the plate and the latex continued to spread, consuming her breasts totally, merging seamlessly with the collar.

Then, once her top had been fully sealed beneath its electric embrace, it began its path downwards, across her chest, her stomach, until—

Twilight continued playing with her, even as the latex descended over her marehood. It flowed around her tongue, Twilight lapping it up and pressing it deep into Luna's folds, and she shrieked as the pleasure overwhelmed her, stronger than anything she'd ever felt in her thousands of years. Her hips betrayed her and thrust forwards into Twilight's ministrations, trying to push her tongue deeper, deeper in.

"Haa! Haa! Haaaagh!"

It was so good it was painful, and it was so painful it was good, and Luna felt more and more of her start to slip away as the latex continued, covering her pussy entirely, running down her back and across her buttocks until her entire body from the neck down was encased in one seamless swath of rubber, her entire body so impossibly sensitive that every slight movement was a jolt of pure pleasure, and still Twilight kept on...

Luna, crying now, forced her mouth shut, squeezed her eyes closed. She had to regain control. She had to. For Twilight. For her sister. For Equestria.

If there was any hope of escaping this, of stopping Sombra, she had to endure.

And endure she did. Soon enough, the latex settled in place, and Twilight withdrew from her crotch, Luna's fluids dripping down her chin.

"It seems," she heard Celestia say, distantly, "that little Lulu is more resilient than she seems."

Twilight began to stand.

"She will need more work, my Knight. What will you do?"

In response, Twilight brought her face towards Luna's. Her fingers wrapped around Luna's chin and, without much resistance, forced her mouth open.

Twilight pressed her lips against Luna's, forcing her into the kiss with a firm grip on the sides of her head. As they kissed, all the foul rubber that Twilight had lapped up from Luna's crotch flowed into Luna's mouth and slithered down her throat.

Twilight's tongue chased it, forcing its way past her lips and playing with her own as she felt Sombra's magic seep down into her core, coating everything it touched on the way, taking her from the inside as well as the out. Twilight's knee lifted, grinding her thigh into Luna's latex-coated marehood and eliciting a moan into her mouth. Their encased bodies slithered over each other, each tiny movement sending waves of overwhelming pleasure cascading through them both.

The kiss was long, and deep. When Twilight pulled out of it, Luna's gaze was foggy and unfocused.

Twilight caressed her cheek. "It feels wonderful, doesn't it? Being smothered under your king's will?"

"Y-yes..."

"Submit," she said. "And you can experience this pleasure forever."

"Y-y-y—"

She wanted to. She wanted to so badly.

"N-no..." she moaned.

"No?"

"I... will not... be broken... yet..." Luna panted out, her cheeks flushed, her body shaking with each breath.

Twilight turned. "Knight-Commander?"

Now, Celestia stepped forward.

"You've done well, Knight," she said, striding forward, hips swinging. "But I will finish her off. At ease."

"Yes, Knight-Commander."

They swapped places, Twilight stepping back to spectate and Celestia stepping close. She observed her sister for a moment, like a butcher appraising a slice of meat.

"You have proved far more resilient that I had expected," she declared. "Your will is strong."

"Sis...ter..."

Celestia circled around her, trailing a finger across her latex skin and making her moan from the touch.

"We will make sure to put that to good use in our King's service."

Her hand came down on Luna's ass, right where the cutie mark would have been, and a gush of fluid bubbled out of her snatch and dripped slowly down to the floor.

"Haaaaa...!"

The latex even made the sharp, stinging pain of the strike feel amazing.

"But why resist?" Celestia asked, sliding in close to her. Her hand slipped under the cup of Luna's breastplate, pressing into her tit and squeezing it.

"Doesn't it feel good?"

Her other hand slithered up, her gloved fingers pressing into Luna's lips and forcing their way inside her mouth.

"Doesn't it feel good to wear your king's armor?"

Luna's tongue ran over the tips of her fingers. Celestia smiled.

"The pleasure will only grow if you submit to it," she said. "It's unlike anything else, sister. The pleasure of giving yourself up... obeying his commands... being reborn as his loyal knight, his will your will, his pleasure your pleasure..."

She gave Luna's breast another squeeze.

"It's simply intoxicating. You want it, don't you? Your body certainly does. Why continue to deny it? Why deny what you know you want?"

Luna couldn't even speak. She just shook her head. Tears and sweat dripped down her cheeks.

Celestia withdrew, pulling her fingers from around Luna's breast and inside her mouth, a trail of drool following them.

"Then perhaps," she said, "You just need a more thorough demonstration."

She circled around to Luna's front. The mask, the only piece for the armor remaining, drifted along with her.

"Rejoice, sister," she said, reaching towards Luna's throat. "You're going to be completely smothered by your king's will, head to toe, completely and utterly consumed by him."

Her fingertips brushed the metal of the collar, even as her other hand wrapped around her own breast.

"The pleasure will be... unimaginable."

Celestia's horn began to glow, and magic flowed from her fingertips into the collar.

Luna tried to focus. What was she...

Then, she felt the latex around her throat begin to move.

Her unfocused eyes widened.

It was moving up.

The latex flowed up her face. It crawled over her chin, crept up her cheeks, slid right over her drooling lips, sealing them beneath a layer of smooth, featureless latex. She tried to cry out, but speech was impossible.

Her eyes rolled back in her head as the grey rubber flowed over them, sealing her in darkness. The ethereal starfield of her mane was swept back as the latex continued its journey upwards, covering her forehead, her horn, her ears, until, finally, every inch of her had been consumed. All traces of her identity had vanished beneath the suit.

It didn't stop there. She squirmed as it began to force its way into her, gushing past her lips and down her throat, tendrils of it creeping into her ears, pressing into her eager pussy and her tight ass. Claiming her womb. Every hole, every entrance into her body was sealed, violated, and taken from her. She couldn't see; she couldn't breathe; she couldn't think.

She loved it. She couldn't deny it anymore. She loved it.

She struggled against the sensations, pulled against her bonds, but every movement just sent a fresh wave of impossible pleasure crashing over every inch of her being, inside and out. She had no control, now; her body tugged and shuddered and twitched all on its own.

The king's magic continued to pump into her, filling her utterly from every entrance. She could feel it sliding deeper into her pussy as her womb was filled, full to burst. Its corruptive influence seeped into her from within.

She needed air, her lungs demanded it, but it was withheld from her as more and more latex forced its way down her throat. Her body tried to gasp for air, but that just pulled more of it into her. The complete darkness seemed to grow even darker.

There was no escape from the latex. It was inside her. It was encasing her. It was consuming her. The last of her conscious thought was pushed aside, both by the instinctive need to breathe and by the throes of her lust, or maybe they were one and the same. The whispers that had been dancing around the edges of her conscious mind rushed to take its place.

She felt something press against her temples. The mask, the whispers told her. Your mask.

The mask pressed into the rubber on her face, bonding with it and affixing itself permanently in place. The pressure only sent more pleasure through her, and if she could have, she'd have screamed. She was right on the edge of orgasm, being held there, needing to come but forced not to by Sombra's magic. The pleasure built and built, her juices practically pouring out of her now, seeping into the suit, and still the floodgates were held excruciatingly closed.

The tendrils of rubber forcing themselves into her ears pushed deeper, deeper. She felt a pinch, somewhere in her skull, and the whispers became a chorus, drowning out all other thought.

Who are you? they asked her. She tried to remember, but she just couldn't recall. What was her name?

Luna, they told her. Servant of King Sombra. His loyal Knight-Assassin.

That sounded right. She let the voices rebuild her fractured mind, tell her who she should be. A creature of the shadows. Her king's left hand. His will was her will, and his will was good.

Trapped in her latex prison, there was nothing she could do but listen as the heat in her body built to a fever, perpetually on the edge of losing consciousness as her lungs strained for breath.

Obey King Sombra.

Obey King Sombra.

Obey King Sombra.

And suddenly, the voice was her own.

I will obey King Sombra.

I will obey King Sombra.

I will obey King Sombra!

The latex muffled her screams as she finally came.

It was a waterfall, the pent-up juices of what felt like an eternity gushing and bubbling out of her. The material of the suit seemed to accommodate her, absorbing the sticky fluids, taking them into itself. To what end? She didn't have the capacity to wonder.

Her body twitched, twisted, struggled and spasmed as she came, and came, and came again, her needy cunt contracting and squeezing around the rubber phallus that had taken her. As it did, the latex there—and all across her body—seemed to settle, to thin, coating the walls of her body but leaving them open for use.

The magic holding her in place vanished, and she collapsed to the floor, still twitching, still coming. The latex retracted into her nostrils, clearing the passages and allowing her to take her first, gasping breath.

As she rode out the last of the orgasms, the area surrounding her eyes split and peeled back, revealing twin pools of deep, bottomless green.

She had broken.

She lay there, her chest heaving as she recovered from the ordeal. One shaking hand moved to her face. She felt the smooth metal of the mask that covered her, making her faceless, sealing her expression beneath cold, unfeeling steel.

A faceless, unfeeling executor of her king's will.

His loyal Knight-Assassin.

Under the mask, she might have smiled.

Calmed enough now to take stock of her surroundings, she sat up. The first things she saw were her Knight Commander and her fellow Knight, embraced, pressing their armored bodies into one another. A thin trail of spit connected their lips.

Celestia pulled away from Twilight, strode over to her.

"Stand up, Knight."

Luna did as she was commanded, struggling quickly to her feet.

"Attention!"

Luna's heels snapped together.

"Salute!"

Her hand snapped to her forehead. The cloak on her back billowed out behind her.

"Who are you?"

"I am Luna, Knight-Assassin of King Sombra. His will is my will." Her voice was muffled, distorted beneath the latex and her metal face. That did not concern her; assassins did not need to speak. They only acted as their king commanded.

"And who am I?"

"You are Knight-Commander Celestia, executor of our king's will. My superior. I will obey your words as if they were his."

"And your master?"

"King Sombra. For the rest of my eternity."

"And his enemies?"

Luna held up a gloved hand. Her fingers curled into a tight fist, as if she were crushing an object in her palm.

Celestia grinned.

"Welcome to the knighthood, sister. Hail Sombra."

"Hail Sombra."

Taking a break from Teatime this week. Got on a latex kick, so have another one of these.

Only one princess left~
