The throne room of the Crystal Empire was normally a very serene, peaceful place.

Today, it was chaos.

"Sixth Platoon!" Shining Armor commanded his men. "Reinforce the southern side defenses! Sombra could be coming from any direction, so stay vigilant! Report anything, no matter how small!"

"Sir!"

The crystal guards saluted and departed, armor clanking as they moved.

Shining Armor paused for a moment to gather his breath. His appearance was haggard, long wrinkles sitting under his eyes.

It had been three days since Canterlot had fallen. With no word from the princesses, nor from Twilight and her friends, they had been forced to assume the worst. Their fears had been justified when the first of the refugees arrived by train.

The situation in Equestria was dire. Sombra's armies had taken much of the continent, with what pockets of resistance remained slowly dissolving under sheer numbers as every captured fighter was added to Sombra's forces. It was likely that the kingdom would be under his complete and total control before the week was through.

Shining Armor was not going to let that happen here. He'd worked tirelessly around the clock, strengthening the Empire's defenses and readying its soldiers for battle.

Unfortunately, after three days of stress and forced insomnia, he wasn't at his best, and so he failed to notice the shadow that flitted between the columns of the throne room overhead.

With his soldiers dismissed, he was left alone in the room with only their personal guard and his wife.

Cadance wasn't holding up much better than her husband. Her task was different; while Shining directed the soldiers, it was her job to ensure that the barrier that surrounded the empire remained intact.

She sat on her throne, eyes closed, horn alight with energies both her own and of the Crystal Heart, floating in its shrine somewhere below them. The court's best mages were down there as well, channeling their own energies into the spell.

They'd learned from the first time Sombra had tried to take the empire that a single shield spell maintained by one alicorn would only buy them time. Now, they were more prepared. This spell would buy them considerably more.

Still, her hands wrung themselves in her lap.

Shining approached her and placed a comforting hand on her shoulder. Her eyes opened, and she smiled, weakly.

"Any sign of him yet?" she asked.

"Still nothing," Shining said. "And that just worries me more. The Empire was his first target when he came back the first time, so why is he taking his time getting to us now?"

"I feel the same way," Cadance said, placing her own hand over his. "But at least it gave us time to evacuate the citizens... and Flurry..."

At this, her expression faltered.

"Hey," Shining said, putting his other hand on her other shoulder and kneeling down so he could look straight at his wife. "Sunburst and Thorax will take care of her. They'll keep her safe until all of this is over. She's in the safest hooves she could possibly be in right now."

"I know," Cadance said. "But what if—"

"Sir!"

A scout burst through the doors of the throne room, galloping at full tilt across the crystalline floor and just barely skidding to a stop in front of Shining.

"Corporal. What's happening?"

"Sombran forces sighted, sir!" the scout said, snapping into a salute. "Forty miles southwest of the border!"

Finally. It was almost a relief..

"Numbers?"

"Hundreds, sir! Maybe thousands! Pegasi, unicorns, and earth ponies, sir!"

"And Sombra?" Shining asked.

"No sign, sir!"

Shining's eyes narrowed.

"Very good, corporal. Send the fourth, seventh, and eight platoons to gather behind the shield to meet them, but do not engage. And tell them to be weary; we don't want to be tricked into a flank."

"Yes, sir!" The colt saluted again and dashed off.

Shining turned back to his wife. "Will you be alright?"

"I'll hold the shield as long as I can," Cadance said. "Go."

Shining's horn glowed, and his helmet lifted off of one of the survey tables scattered haphazardly across the floor.

"I love you."

"I love you, too."

And with that, Shining bolted out of the throne room. The doors slammed shut behind him.

Cadance furrowed her brow. She closed her eyes once again, to put all her focus onto the spell. The barrier would be coming under attack, soon, and it would take everything she had to maintain it once it did.

Several minutes passed in relative silence.

And then...

Thunk.

Cadance's eyes snapped open, just in time to watch as one of her personal guards collapsed to the ground, hands clutching at his throat.

Thunk. Thunk.

Two more guards dropped. Cadance saw a glimmer of steel jutting from their windpipes.

The other guards drew their weapons, swords and spears.

"Protect the princess!"

They moved quickly, backing up to form a protective barrier around the throne. Cadance, meanwhile, had leapt to her feet. Her eyes darted about, trying to spot where the attacker was. Her horn sparked, surrounding them in a weak barrier; she couldn't afford to take anything away from the larger shield that surrounded the Empire.

"Above us!" one of her guard shouted. Cadance's head snapped up, and she saw them: a cloaked, hooded figure hanging off the top of one of the pillars. She tried to make out their face, but all she got was a glimpse of steel before the figure leapt off the pillar, sailing down towards them.

The guards raised their weapons to meet the assailant.

It did very little good.

Something sparked under the intruder's hood, and Cadance's shield shattered instantly under the force of the counterspell. The attack knocked her to her knees, and her horn flickered.

A moment later, a rain of daggers dispatched the rest of her guard.

Cadance coughed. She couldn't understand it; even weakened, even with her diverting most of the energy into keeping up the barrier that surrounded the city, her shield spell had the power of an alicorn behind it. Who could have possibly had the strength—

A sudden cold took her horn, and she glanced up. She watched in horror as the black crystals sprouted from it... and the light of her magic flickered and died.

"No..." she whispered.

The shield was down.

Something took hold of her wrists and lifted her into the air, arms outstretched above her. Her feet were similarly taken a hold of, held in place in midair by a dark blue aura.

She forced her head up, got her first real sight of the intruder. The figure wore a long hooded cloak that extended to the floor, obscuring most of their body. However, as they turned towards Cadance, the cloak parted and was swept behind them, revealing light armor fitted over a shiny bodysuit, and sculpted around their very feminine body. The figure reached her hands up—gloved hands, the same cold, grey, rubbery material that seemed to encase the rest of them—and grasped both sides of the hood, pulling it back.

Cadance gasped.

What lay under the hood was more of the strange latex, which seemed to wrap totally around their head. A metal mask, devoid of any expression or features save from a pair of holes for the eyes, took the place of their face.

But there was only one mare that billowing starfield of a mane could belong to.

"A-Auntie Luna?"

The figure—Luna, or whatever remained of her—said nothing, merely stared at her from behind the mask with those brilliant green eyes, expression completely obscured. Then, they turned, and from a pouch within the cloak she retrieved a black crystal, about the size of her palm. Turning away from Cadance, she crossed over to the center of the room.

Luna placed the crystal on the ground and backed away from it. After a moment, it began to glow a sickly purple. Smoke of the same color began to seep from it and into the air, forming a swirling disk; a portal.

And from that portal emerged a figure, sneering, his head held high.

"Hello, 'Crystal Princess'," King Sombra said.

Cadance's eyes widened, her fear showing—but then she forced it down, her eyes narrowing into a look of hatred.

"Sombra."

Sombra stepped further out of the portal. As he did so, two more figures followed him—and Cadance had to fight her fear instinct a second time.

These two were dressed in more aggressive steel armor, and each also wore matching bodysuits like the one that adorned Luna. However, where Luna wore a mask, these two wore helmets—and after they emerged from the portal, they removed them, revealing two familiar faces.

"Auntie Celestia?" she gasped. "T-Twilight?"

"Yes," Sombra said. "Although, not quite as you knew them. As you can see, they have chosen to serve me now."

As if to demonstrate, the two snapped to attention.

"Hail Sombra."

"No," Cadance said. "No, this is a trick. Celestia and Twilight would never—"

"Oh, but they have," Sombra said, chuckling. "And your 'auntie' Luna, too. They've all pledged themselves to me as my knights."

He turned to Celestia and Twilight.

"Strip her. I want to see the totality of my conquest before she is... broken in."

The two of them saluted, and approached her, their helmets left behind.

Celestia's hands went to the neck of Cadance's silken dress, grabbed a fistfull and ripped it off of her. Her undergarments were a dark crimson; they too were torn off with little grace, leaving her shivering in the cold castle air.

Sombra stepped forward, slipped his hand under her breast. Cadance grit her teeth as he surveyed his prize.

"My, my," he said. "You are just as luscious as I imagined."

"What do you plan to do?" Cadance spat. "Have your way with me?"

"Yes," he said. "Among other things, my Crysssstal Princess."

He stroked his hand across her cheek.

"Or should I say... my Queen?"

"Queen?" Cadance spat. "What are you talking about?"

"That will be your royal title," Sombra said. "Once you've given your mind—and your body—over to me."

"I'll never become your queen," Cadance growled. "Or anything else of yours!"

"Oh, but you will," Sombra said. "By the time I've finished with you, you will be totally, utterly devoted to me. You'll want nothing more."

"Now, my knights," Sombra he said, settling onto Cadance's throne. He rested his head against his hand, smirking down at her. "Prepare my Queen."

"Yes, my king," the three chanted in unison. As one, they turned on Cadance.

As they stepped towards her, Cadance's teeth grit.

"You mustn't listen to him!" she said, as they came closer. "He's corrupted your minds! Please, fight it!"

"Oh, my dear, sweet, naive little niece," Celestia purred, reaching out and stroking Cdance's cheek.

"We know he has," Luna said, as she removed her metal mask, the grey latex flowing back and away from her face, stopping only when just her cheeks felt its touch.

"And we love it," Twilight finished, kneeling at Cadance's feet.

"The power."

"The purpose."

"The pleasure."

"No!" Cadance cried, struggling against her bonds.

"Yes," Celestia said, stepping to Cadance's right, her sister mirroring her on the left. She brought her lips close to Cadance's ear.

"And you will too."

At some unspoken signal, the three moved in as one. Celestia and Luna both pressed their bodies into Cadance, the cold, flat metal of their armor and the cool, slick latex that coated their bodies grinding into her sides.

Celestia's hand traced its way up her stomach, across her chest, and up to her breast, while Luna's slid down, past her navel. She shivered under their touch.

This was nothing compared to the reflexive jerk when Twilight kissed her marehood.

"Gah!" she gasped, as Twilight's lips brushed against her own. "T-Twilight, what are you—"

Her mind blanked as Twilight sucked a little of the sensitive flesh between her teeth and gave it a gentle nibble.

Celestia's hand wrapped around her breast, squeezed it. At the same time, her lips pressed against Cadance's neck, and she kissed her way up along its length before gently biting her ear.

"Ngh... Auntie, please, don't—"

Luna's fingers began to massage her clit, even as Twilight's tongue delved into her pussy.

Cadance's back arched, her head tilting upwards as her teeth grit. "T-Twilight, stop!"

But Twilight didn't stop. Her tongue plunged deeper, probing and rubbing, feeling for her reactions. It quickly settled into a rhythm, running up and down, up and down...

She could feel her body betraying her, her nipples hardening, her slit growing moister with every pass of Twilight's tongue. A heat began to build in her cheeks. And the whole time, Sombra looked down at her from his throne, with that same, damnable smirk, and she knew there could only be worse things in store.

"There's no one coming to save you this time, princess," she said, gloating, having noticed her eyes flick towards him. "The alicorns have fallen. Twilight Sparkle has fallen. The Element Bearers have fallen. Equestria is mine. There's no one left. I've taken them all."

"You'll never... win," Cadance spat past gritted teeth. "Never!"

"Oh, but my poor, poor Cadance..." he said, smiling, fangs on full display. "I already have!"

Luna's gloved fingers ground into her little puffy nub, and she had to fight to keep down a moan. Celestia continued to play with her tits, rubbing and massaging them. And Twilight kept working her pussy, now fully wet, dripping. And all she could do was watch... and hope to whoever or whatever was listening that she didn't let herself start to enjoy it.

She was a mother. She'd made it through that. She could make it through this. All she had to do was get through to one of them.

"Twilight, please," she gasped out. "I'm your sister-in-law. I foalsat you when you were just a little filly. Your brother, Shining—I know how strong your bond is. Sombra is going to hurt him, or worse. You can't side with this monster over your own famil—AGH!"

A sharp pain surged through her rump, like a slap—Celestia had slapped her, just behind the cutie mark. "You will treat your king with respect," she growled.

"Auntie," Cadance said, switching targets. "You took me in. You practically raised me. I know I meant something to you. Please, focus, try to remember!"

"Pleading will get you nowhere," Luna whispered, into her ear. "We have all sworn our eternal allegiance to King Sombra. We are his down to our very cores."

She punctuated the statement with another rough grind of her latex-coated fingers into her clit, and this time Cadance couldn't keep the moan down. No, she had to fight—"

"I think she is ready, Knight-Assassin," Celestia said.

"I agree, Knight-Commander," Luna replied. They both turned to look to their king, giving Cadance a brief respite, at least from their ministrations.

"You may begin, my servants," he said. "Begin the final breaking of the so-called princess of love."

The two seemed pleased at this. "Hail Sombra!"

"W-what does he mean?" Cadance stammered.

"Shh," Luna said, once more taking Cadance into her embrace.

"Just relax," Celestia said, doing the same. "Bask in the pleasure as your will is bent to our King's..."

She trailed a gloved finger across Cadance's belly... and it left behind a trail of gray in its wake.

Cadance's eyes widened as the same substance that coated Celestia's body began to creep onto her own. Where it touched her, her skin seemed to prickle, to heat up.

And it was spreading.

"What?" she breathed.

"Your king's love," Celestia replied. Her hand trailed back up, to her bust. "Embrace it."

"N-No!" Cadance squealed, as the strange stuff spread further along her skin. It traveled slowly, agonizingly, and as more and more of her pink coat began to disappear under its surface she felt herself getting hotter and hotter.

Celestia squeezed her breast, digging her fingers into it, and Cadance shrieked as latex began to flow down Celestia's hand and spread across her skin. The pleasure of the celestial alicorn playing with her tits before had been moan-inducing, but this was excruciating.

Luna's fingers drifted to the back of her neck, trailed down her spine, leaving more of the latex behind in its wake. The rubber on her front had reached her naval, now, not flowing over her belly button but into it, coating every surface and hiding nothing. And still it crept down, down...

Celestia seized her other breast and Cadance shrieked a second time as the latex began to flow across her raw, already sensitive nipple. The shriek turned into a long moan as it spread across both breasts, the shape of each nipple perfectly preserved. The others were wearing suits; she was getting a second skin, in every sense of the word.

Her eyes rolled up in her head, the sensations wracking her body becoming just too much to bear. She panted, and the substance kept spreading, consuming more and more of her. It was reaching down, now, and she could feel it getting closer, closer to her clit, two inches, one inch—

She didn't need to count. Luna's gloved hand pushed into her clit, drowning the wet, needy nub in latex.

Cadance screamed, her back arching, arms and legs pulling against their restraints. She thrashed, and moaned, and kicked and shrieked as the most sensitive part of her body was squeezed, pressed, and molded by the all-consuming latex, spiking her sensitivity and utterly blanking out everything else. Luna worked it into her, rubbing it against the clit, and she kept shrieking and moaning as it continued its path down.

Most of Cadance's torso had been covered now, with just a few, slowly disappearing spots of pink remaining. Celestia's hand moved down to her buttocks, rubbing and squeezing them, spreading the accursed substance across their tight surface. At the same time, she leaned over, pressed her lips against Cadance's and forced her tongue into her mouth.

The latex dripped further down, across her thighs, her cutie mark, but—most mind-numbing of all—it also spread around her marehood.

Luna continued to work her clit, but once the fleshy nub had been completely passed it was Twilight's turn. Her tongue worked magic, lapping against her slit even as the foul rubber sought to encase it, pushing more of it deep into Cadance's passage with each lick. She could feel it, pushing past her defenses and into her dripping snatch, coating the fleshy passage as it reached towards her womb. Behind her, Celestia's fingers began to piston into her asshole, doing much the same there.

She began to thrash, reduced to base animal instincts by the onslaught from all sides as the last of her torso disappeared and the crystal heart on her hips began to be swallowed. Celestia was forced to retreat from her mouth, but no sooner had she done so than Luna had moved to take her place, grasping both sides of her head firmly and forcing her lips over Cadance's.

Cadance moaned into the kiss as the last of her cutie marks, her birthright to the Crystal Empire and the symbol of love, disappeared under Sombra's gray.

Luna's tongue darted between her lips, pushed them open. Cadance became dimly aware of something else pushing its way into her, through her mouth, and realized that Luna had had more of the latex inside her, that it was now slithering down her throat, coating and seeping into her from the inside.

More and more of the latex slipped down her throat, pumped into her through Luna's kiss, a deluge. She wanted to gag, spit it out, but she couldn't. Luna's hands held her still.

Cadance's arms were now covered. The latex dripped down, submerging the tips of her fingers, and the feeling made her twitch. Twilight continued to lap at her cunt, Celestia continued to play with her asshole, and Luna continued their kiss. There was nothing she could do; it was invading her from every orifice, flowing deep into her, corrupting her very being from within.

No escape.

She felt it pouring into her womb, her core, coating it, taking it in Sombra's name.

No escape.

The stuff bubbled from her asshole, Celestia still playing with it, trying to force more in.

No escape.

She moaned into Luna's deadly kiss as more and more of Sombra's magic poured into her.

No escape.

The last of the latex flowed down her ankles, over her feet, forming into a pair of heeled boots.

She was now coated from the neck down, every detail, every curve on exhibit.

Her chest heaved. Her cheeks burned. Her body longed for release. Sweat dripped down her forehead, tears dripped down her cheeks, drool dripped from her mouth, and her juices dripped from her pussy, now outlined in skintight latex.

The three knights pulled away from her holes, instead opting to play with her body. Twilight wrapped one arm around her thigh while the other pressed two fingers into her rubbery snatch, while Celestia and Luna each lowered their heads to their respective breast and began to tease her with their tongues and teeth.

The loss of their intrusion in her holes was almost maddening... but it only mattered for a second, because then the suit came alive.

Its surface began to ripple, to twist, to flow across her body once more, filling in every pore. She felt the latex inside begin to squirm, to fill and coat her, to seep into her and turn her, every inch of her, into Sombra's plaything. The pleasure was unbearable, her hips bucking, her arms thrashing, a constant mix of screams and moans leaking from her mouth.

The three knights began to speak, Celestia and Luna whispering into each ear.

"Do you feel this pleasure?" Celestia asked.

"Yes! Agh!" Cadance shrieked.

"Do you love this pleasure?" Luna asked.

"Yes!"

"Do you want more of this pleasure?" Twilight asked.

"Yes!" Cadance cried. "I need it! I need to come! Give me more, please!"

The three's ministrations increased in vigor, and her eyes rolled up into her head, her tongue lolling out as the pleasure destroyed her, leaving her totally, utterly blank.

"Only King Sombra can fill you with this pleasure."

"Only King Sombra can satisfy you."

"Only King Sombra can give you what you crave."

It was too much. She couldn't take it.

"Yes!" she shrieked. "Yes!"

"Obey King Sombra."

"Worship King Sombra."

"Love King Sombra."

"I will!" she shouted. "I will—"

"Hail King Sombra."

"Hail King Sombra."

"Hail King Sombra."

"Hail King Sombra!" Cadance screamed."Hail King Sombra! Hail King SombraaaAAAAAA!"

She came.

Her pent up juices flooded out of her, dripping down Twilight's fingers and hand. She threw her head back, mouth twisted into a raucous smile. He twitched and spasmed as more and more of her juices sprayed out of her, sliding down her legs, puddling on the floor.

The magic holding her disappeared and she slumped to the floor, the last of her orgasm draining out of her as she lay, chest heaving, on the cold crystal.

"Haiiiillllllll..." Cadance choked out.

She was given a minute to recover, no more, before Sombra opened his mouth. One, singular command.

"Rise."

At this, Cadance, stumbling, got to her feet. Her eyes turned towards the king. They had not been totally consumed by the green of his magic, not like the others, but wisps of purple smoke drifted from their corners all the same.

Sombra had, at some point during the proceedings, removed the majority of his armor, particularly around his muscular chest and his groin, though his ostentatious cape remained. His cock was fully erect and on display, a massive pillar of black flesh that made Cadance's heart flutter.

"Who are you?" Sombra asked.

"I don't... I don't know," she said, her vision fuzzy.

"Who am I?"

"You are my king," Cadance said. That she was certain of.

"Would you like me to tell you who you are?" the king said.

"Yes," Cadance said. "Please, my king."

Sombra smirked.

"You are my queen," he said.

"I... I am?"

"Yes," Sombra said, looking down at her from the throne, his cock throbbing. "My love, and my lover. Bearer of my heirs. You love me with all your heart... Queen Cadenza."

"I... I do," she said. "Yes..."

"Come, my queen," Sombra said. "Let me remind you of our union."

He shifted in the throne, spread his legs, letting his member entice her.

"Well?"

Cadance licked her lips. She was already growing wet again, looking at her king's shaft.

"I want nothing more, my king."

Sombra smiled. "Good. But first, let's get you in something more... fitting to your role."

Sombra's horn lit, and the suit came to life once again. Cadance moaned as it shifted, changed color, fading to a deep, dark crimson. Windows opened up over her breasts and her stomach, leaving her naval exposed, their edges seductively curved and pointed like licking flames against her bosom.

She recovered quickly, admired herself.

"I love it, my king."

"I know you do," Sombra said. "Now come; pleasure your king."

Cadance strutted up to the throne, hips swinging, latex creasing as it moved and adjusted to her walk. Sombra watched, amused, as she approached him and knelt at his feet, her face just inches away from his cock.

His musk filled her nostrils. Cadance was awed by the size of the thing; truly, fit for a king!

She crept forward the last few inches on her hands and knees, then, slowly, kissed the skin above his ballsack, right at the base of the shaft. The smell was intoxicating, and she was already beginning to drool.

Caressing it with both hands, she slowly kissed her way up its length, past the medial ring, until she reached its head. It throbbed with arousal, but her king was calm, watching her intently with that same amused smirk.

She ran her tongue around his head, and then, her new skin giving her an affirming burst of pleasure down her spine as she did so, took him in her mouth.

She began to work her way down his thick shaft, slowly, letting it push further and further back into her throat. She had vague memories of doing this before—of doing it a lot, actually—but she couldn't remember who it had been with.

It must have been the king. Who else would she have given this kind of treatment?

With practiced ease, she fit him down her throat, bobbing up and down slightly, slowly making progress down the shaft, until her throat bulged against the collar of her suit and she couldn't fit any more.

As she slowed down, Sombra shook his head. "No, dear Cadenza, that just won't do."

He grabbed her by the hair on the back of her mane and yanked down, forcing her further onto his cock.

It should have hurt—but all she felt was pleasure at having served her king better. She moaned into his cock, then began running her tongue around it, tasting the salty, meaty exterior. Her hands went to his testicles, rubbing them, cradling them as Sombra forced himself deeper down her throat.

It was getting hard to breathe, now, but she didn't dare let up. It wasn't until her cheeks started to turn blue that Sombra released his grip on her hair, and she was able to pull up enough to breathe again.

Then, she went down again, pushing herself until she felt tears in her eyes, and she felt his cock throb in her throat. She slid back up, running her tongue along the edge of his member on her way up. Up and down. She started to get into a rhythm, as natural as breathing, and with each successive push she felt an electric tingle run down her spine, into her nethers, which she knew were starting to drip again.

She wanted him inside her so badly. Needed it.

After one last lick up his shaft, she pulled off the tip of his head, a strand of pre stretching from her tongue.

"Why have you stopped?" he asked her. Demanded of her.

She kissed his shaft one last time.

"I need you, my king. Please, fuck me. Use me. Fill me. I am yours."

His smirk deepened, and every second he didn't answer was agony.

"Very well, my queen," he said.

She smiled, ecstatic, and rose to her feet, fighting the urge to leap upon him with all the dignity of a hungry lioness. No, she was his kitten. His pet. His queen.

She swung one leg up, then the other, kneeling across his lap. His member poked into her backside, she could feel its warmth leaking over the cool latex and it filled her with anticipation. Slowly, she rose, giving him room to work.

His large, muscular hands grasped her ass, guiding her into place over his cock. He held her there, his head grinding into her lips.

"Beg for it, my queen," he said, looking sly.

"Please, my king," Cadance said. "Please use me like the whore I am. Rut me until I cannot stand."

Sombra's fleshy head plunged into her latex-lined crevasse.

It was slow, at first, but Sombra was not a patient lover. Her vagina already stretching to accomodate his girth, he thrust upwards until he had hit the medial ring, then pulled back, thrust again, and again, and again, pushing deeper into her each time.

Cadance's tongue lolled out. Her eyes had rolled up in her head with the first thrust. Drool trailed from her gaping, smiling mouth as Sombra fucked her senseless.

"Ah! Ah! Yes!" she gasped out. "Yes, my love! Fill me! Harder! Harder!"

Each thrust felt like a spike of pure pleasure being driven into her brain. It was impossible, indescribable. Her hips ground into it, matching his rhythms and doubling their ecstasy. Her entire world was the cock that was penetrating her, filling her, inching closer to her womb with each thrust.

His hands clenched harder on her hips, pulling her down further onto him. Cadance cried out as his monstrous cock struck her cervix, but the corruption that had taken her turned the intense pain into even more pleasure, and it sent her over the edge. She cried out again as she came for her king for the first time. The first of many to come.

Her fluids bubbled out around Sombra's girth, dribbled down his balls. He didn't even slow down.

"Ah! Ah! Ah! Ah!" Cadance cried out, consumed by the ecstacy. For the second time that day, her mind broke.

All that mattered was her king's cock, filling her utterly, completing her. She never wanted it to end.

Her back arched as she came again.

"Ah! My king!"

"My queen," Sombra said back. "My crysssstal princess. And only mine."

"Yes!" Cadance gasped out. "Yours! Only yours! Now and forever!"

"Then let us seal that pact."

His thrusts redoubled, his stamina apparently limitless. Cadance's mind once again blanked as she rode him, thrusting into his thrusts, grinding her hips, screaming his name.

And then, after what felt like an eternity, she felt him stiffen and relax as he climaxed, his cock twitching as it pumped her full of cum.

Sombra's seed flooded into her womb, and the euphoria was indescribable. Her king had bred her, and just the thought alone made her cum again. Her wings flared up as she ground her hips into his member, riding out her own orgasm and milking every drop of cum out of Sombra's cock. She was in heaven.

Eventually, the jets of seed slowed to a trickle, and, spent, she let herself collapse onto his chest, her breathing heavy. As the head of Sombra's girth pulled out of her, she felt the walls of the latex that encased her seal behind it. Her crotch became a smooth, featureless expanse, locking Sombra's essence inside her in its totality.

She felt bloated and full, her king's seed sloshing around inside of her.

She purred.

"It seems you have enjoyed yourself, my queen," Sombra said. In response, Cadance reached a hand up to his jaw, caressed it, and pulled herself up into a deep kiss. Sombra's long, dexterous tongue played with her own, and she melted into him.

Eventually, he pulled out of it.

"Let us try this again," Sombra said.

"Who are you?"

"I am Cadenza," Cadance said. "Queen of the Crystal Empire. Lover of King Sombra. Bearer of his heirs."

"And who am I?"

"You are my love, my king."

"And what is your role?"

"To please you," Cadance said. "To be rutted by you."

"Good," Sombra purred. "And them?" he added, gesturing at the three knights who had turned her. Her auntie who had raised her. Her other aunt, who had shown her nothing but kindness. And the filly she had helped to guide into a strong, powerful mare.

"Our knighthood," she said. "Our servants. Your servants, just as I am your servant, my king."

"And Shining Armor?"

Cadance smiled.

"Your future slave, my king."

Sombra laughed, and sat on his chest as she was, she could feel the deep reverberations, and she never wanted to get up.

"Cadance!" Shining shouted as the doors to the throne room burst open.

He was in a bad way. His armor was scratched and burned from mana blasts. His coat was dirty, and cut in half a dozen places.

But his eyes were the worst of it. His eyes were full of fear.

He'd been at the front lines when the shield had dropped. He'd known what that might mean.

They'd held out as long as they could against Sombra's forces, but in the end, without Cadance's magical protection, they hadn't been enough. They'd been forced to retreat as more and more soldiers fell, and more and more soldiers were turned.

In the end, Shining and the few who remained had turned back to the castle, hoping to fortify that position... only to find it had been taken over, the guards and mages left behind already wearing Sombra's accursed helmets.

Desperate, Shining had fought his way back to the throne room. He knew he might well be the only loyal pony left in the Empire. At this point, he didn't care. The Empire was lost. All he could do is try and save his wife... or whatever might be left of her.

But as he stepped into the throne room, chest heaving, strength beginning to fail him, his eyes grew wide, and his spirit shattered.

He hadn't been prepared for this.

"Hello, Shining Armor," King Sombra said, from atop the crystal throne. But it wasn't the dread king of shadows that Shining's eyes were drawn to.

Her legs sat draped across his lap. She hung off of him, like a piece of jewelry. Her had traced down his chest, gloved fingers caressing his skin. She looked at him, eyes smoldering, as the crimson bodysuit that encased her creaked and twisted, accentuating every familiar curve.

"Hello, Shining," she said, a twisted, seductive smile on her face.

"C-Cadance?" he whimpered.

"Allow me to introduce my new queen," Sombra said. "But I think you two may already be acquainted."

Cadance wrapped her hand around Sombra's neck and pulled herself up to plant a kiss on his jaw. Her eyes slipped sideways, watching the beaten soldier.

Shining collapsed to his knees.

The sight sent a fire up her nethers.

Sombra's fingers ran through her hair. He nodded to the side. One of the other slaves brought him one of the accursed helmets which had twisted the minds of Shining's comrades, breaking them to Sombra's will. The dread king took it in his hands.

"Would you care to do the honors, my queen?" Sombra asked, with a devilish smile.

"I'd be honored, my king," Cadance said, smile matching his. Just saying the words made her breath quicken as her suit rewarded her.

She slipped off of Sombra's lap and strode down the steps from the throne, hips swinging, heels clicking against the crystal, latex creaking with every step as it wrinkled around her hips. The helmet swung from her gloved fingers.

He watched, numbly, as she approached, stood over him, her legs slightly apart, enough that he could see her sex... and the traces of fluids leaking around it.

"Cadance, please," he pleaded. "Don't... don't do this."

She laughed. "Oh, Shining... don't worry."

Her smile was cruel as she lowered the helmet over his ears.

"You'll make a wonderful slave."
