It was a typical afternoon in the Crystal Empire. The sunlight danced brilliantly off the many gleaming, multifaceted crystalline buildings in the town square. Outside the magical barrier that kept the brutal wintery weather of the frozen north at bay, a frosty squall raged, pounding the walls of the arcane dome that surrounded the empire with snow and ice. From inside however, the result was quite a beautiful display of sunlight reflecting off the snow. For all intents and purposes it was a normal day, the kind of normal day that typically heralds the onset of some terrible catastrophe.

This catastrophe came in the form of a small, yellow and black rubber package which appeared in a burst of green flames at the foot of the throne right before Princess Cadance herself and her husband, Shining Armor. Unbeknownst to them, this package was actually the former pony, Derpy Hooves who, after having been transformed into a horny stallion drone by a mysterious plague sweeping across all of ponykind, had been reshaped into a small package out of sheer, unbridled frustration by Princess Twilight Sparkle herself. This very package had been, also out of sheer, unbridled frustration, stuffed inside the conveniently placed mailbox which was actually the former dragon, Spike who, after having been transformed into a horny dragon drone by that very same mysterious plague sweeping across all of ponykind (and dragonkind), had been reshaped into a mailbox out of sheer, unbridled frustration by Princess Twilight Sparkle herself. Needless to say, it's probably safe to assume none of the following events would have happened if it weren't for the sheer, unbridled frustration of Princess Twilight Sparkle.

Oh look, a package from Twilight? I wonder what it could be? Cadanced asked, recognizing the familiar burst of green flame signaling a delivery by Twilight's dragon-now-mailbox, Spike.

Hmm, that's strange, I can't seem to find any way to open it. Shining Armor mused, turning the cube of rubber over in an attempt to locate any kind of opening.

A more astute observer might have noted the soft, barely audible, horny moaning coming from deep within the box as Shining Armor poked and prodded at it's somewhat malleable surface, the drone within being squished into its own very sensitive bulge. Cadance, however, was more focused on a far more concerning development.

Shiny! Your hoof! She exclaimed, drawing Shining Armor's attention to the patch of thick, black rubber creeping up his forehoof from where he had touched the package.

Aah! Get it off! Shining Armor flailed his afflicted hoof in vain before attempting to zap the substance off with his magic, the bolt of blue unicorn energy simply bouncing off the glistening surface as if the powerful spell were nothing. My magic's not working on this stuff, Cadance! Help! He cried out in despair.

Cadance summoned the most powerful alicorn healing spell she could muster whatever this stuff was, she wasn't going to mess around if her husband was on the line. With the crackle of energy befitting of a Princess of Equestria and a shower of pink sparks to match, Cadance rose into the air, eyes aglow with arcane power as she inundated the glistening black substance with a blast of pink alicorn magic from her horn. The sounds of the spell reverberated throughout the chamber, and a bright flash temporarily blinded any onlookers. When the smoke cleared, Cadance was left flabbergasted to see that, despite the visible scorch marks on the floor surrounding Shining Armor, she had not even slightly slowed the creeping black substance's progression up Shining Armor's hoof.

It must be some kind of powerful curse, Shiny, my magic's not working! Cadance took a deep breath, trying to maintain her composure. Panic wouldn't do them any good. Quick, to the Crystal Heart. If anything can break whatever dark magic this is, it's that!

Cadance and Shining Armor rushed from the throne room, panicked guards in tow in case either of their leaders issued orders. Shining Armor awkwardly limped, not wanting to walk on his afflicted hoof, which had now been covered in black goop up to his knee, the shiny black substance in stark contrast to his pristine, white coat. Together, they burst into the Crystal Heart's chamber, a large array of crystalline spikes holding the powerful artifact aloft, wide windows overlooking the square below. Having heard the sudden commotion, crystal ponies had started to gather in the town square to watch the events unfold far above them as their royalty desperately rushed to the empire's most valuable possession a mighty heart-shaped crystal that powered the barrier which kept the magical winter at bay and gave the crystal ponies their trademark crystalline coats.

Shining Armor hurried to the side of the Crystal Heart, holding his rubber-coated hoof up to the radiant glow. Surely their most powerful artifact, capable of repelling the most evil of forces, would be enough to cleanse this curse.

The rubber gripping Shining Armor's hoof recoiled as if it were alive, the magical energies of the Crystal Heart seemingly too strong for it. Peeling away from Shining Armor's hoof bit by bit, the black substance writhed and hissed.

Yes, it's working! The two cheered in unison, emboldened by the malign substance's retreat.

The two thought this mysterious scourge had finally met its match. They thought wrong.

The black goop leaped from Shining Armor's hoof and, in the blink of an eye, latched directly onto the Crystal Heart itself. Princess Cadance cried out in shock. Shining Armor and the guards could only watch in silent awe. The crystal ponies in the city square below could barely see what was going on from such a distance through the chamber's open balcony, but it seemed like something exciting was happening, so they gasped as well, because that seemed like the appropriate reaction.

The glistening black rubber quickly enveloped the Crystal Heart, wrapping around the radiant gemstone entirely in a matter of seconds. Cadance, quick to act, responded with all the magic she could call to her command in a vain, last-ditch effort to free the Crystal Heart from whatever was attacking it. Needless to say, it didn't work.

The Crystal Heart, now covered in glistening, black rubber, shuddered briefly, its entire existence being warped and corrupted beneath the coating of shiny latex. As the Crystal Heart faltered, so too did the magical barrier, and a cold wind suddenly broke through, carrying with it a blast of snow and ice. The Heart began to radiate with a sinister acid-green aura, a pulse of energy rippling out and coursing through the very fabric of the Crystal Empire. The black Heart slowly collapsed in on itself, its rubber form melting down into a floating orb, its former shape lost to the corruption from the floating black orb, three smaller arcs of black rubber grew and pinched themselves off from the main body, rotating slowly around the central orb. Cadance's jaw dropped in disbelief as the once-mighty Crystal Heart was reshaped before her eyes.



The strange symbol hung there in the air, spinning slowly about its vertical axis, pulsating with that strange, green energy.

Another mighty pulse of green energy rippled outwards, and with it came a force felt by every single crystal pony within the entire empire. The magic of the former-crystal heart resonated within every pony of the Crystal Empire when it changed, so too did the ponies themselves. All at once ponies were either brought to their knees or forced to clutch their heads in their hooves as the corruption assaulted their bodies and minds universally. Mares and stallions alike found their hooves straying mindlessly between their legs to stroke at a swiftly growing rubber bulge, an incredible horny urge overtaking their thoughts as their bodies were rapidly converted into simple rubber drones, huffing and moaning uncontrollably as the last of their free will ebbed away. All across the empire, cutie marks were wiped away, replaced by that symbol, the ponies within left huffing and groping, moaning in pleasure.

Cadance and Shining Armor watched in horror as the ponies they knew were quickly reduced to mindless, horny drones all around them.

What's... happening? Shining Armor managed to ask, the intense magic worming its way into his brain, overwhelming him with horny thoughts. The stallion instinctively reached for his crotch to relieve the growing sexual urges, his hoof slowly turning a bright shade of pink.

Cadance made as if to reply, but was cut off by her lips fusing shut as her own snout was converted into glossy, black rubber. Her panicked expression quickly gave way to confused ecstasy as she felt her now-black rubbery hoof reach between her legs and probe at a throbbing sensation coming from her crotch. Her hoofshoes, now thick-soled yellow boots, dug into a moist patch and a wave of sheer pleasure rushed through the Princess' brain.

Unngh, I can't thinnaooouhh? Shining Armor's words were stopped short by his mouth freezing open in an O-shape, a hard rubber ring forming over his lips as his white coat began to turn to glossy pink latex rubber. Shining Armor's vision began to tint as a pair of glowing, blue lenses coated the prince's eyes his pink drone mask nearly complete.

Princess Cadance continued to poke and prod at the growing shape protruding from her crotch, falling to her haunches as she stroked uncontrollably at the smooth, hard black shaft that stretched outwards, pushing its way out of her rubbery body, dribbling with a viscous clear fluid. She moaned involuntarily, muffled by the mask covering her face as her forehooves caressed the stiff member, pinched between her solid yellow boots, waves of pleasure washing over her horny mind as her pink coat gave way to glossy black rubber and matching blue lenses forming over her mask.

Shining Armor clutched his head in his pink hoof, the bottom of which had also solidified into a sturdy, rubber boot. It was far too hard for him to think straight as his mind was flooded with horny thoughts. Unlike Cadance however, Shining Armor soon found that he was without any means to pleasure himself as his stallionhood receded into his body, inverting and giving way to a deep hole that tunneled inside him. He gently poked at its rim, feeling strangely hollow so empty, so incomplete! He huffed as the last of his thoughts washed away, his steady breathing whistling softly through the open hole on his face. The former stallion's eyelids drooped over the lenses, thick eyelashes protruding from her new bedroom eyes.

Meanwhile Cadance continued aggressively rubbing at his newly-formed rubber cock his thick hoofboots only helping to amplify the pleasure. Yet he needed more, far more! He needed to fuck something! Cadance rose to his feet, huffing angrily through black filters on his newly-masked face, scanning the room for something to dominate. Cadance's gaze settled on the confused Shining Armor she would do nicely. He stomped his way behind the once-mighty Shining Armor and pushed her onto her belly, positioning himself atop her and thrusting his hard, black rubber cock into her tight, pink rubber ass.

As their conversion into rubber drones completed, Cadance energetically dominated his former husband, aggressively fucking her rear, cementing their new relationship as a drone king and his fucktoy. Shining Armor whimpered as her stature shrunk, her stocked stallion form shrinking to that of a more diminutive fucktoy, while Cadance's lithe princess body grew bigger, thicker and more muscular more suited to her new role as the king of the Rubber Empire.

Yet another green pulse ripped across the former Crystal Empire from its rubbery core, a mix of crystal magic and the strange, mysterious energies of the drone affliction combining together as one. The barrier was decimated, unable to withstand the combined assault from inside and out. The cold ice and snow began encroaching on the city within, winds howling throughout the city of horny drones. Meanwhile, the strange blend of crystal and rubber magic caused a bizarre reaction in the drones throughout the city who continued unaware of the weather around them. As they rubbed, groped and writhed in a vain attempt to pleasure themselves, the drones gradually slowed to a stop, one by one their rubber forms solidifying; slowly converting into a hard, solid rubber. Within a matter of hours, the entire population of the former Crystal Empire had come to a complete standstill, frozen in place. All but the city's royalty, who continued to fuck passionately and ceaselessly over a city of motionless rubber drone statues.

Shining Armor eagerly sucked on her master's hard, rubber cock as he thrust himself into her his black shaft filling that strange, sexual void inside her, while her holes provided the drone king some semblance of temporary relief from his overpowering sexual desires - their minds both completely overtaken by their horny drone urges. Cadance withdrew his stiff rubber cock from Shining Armor's mouth with a wet pop, thick fluids dribbling to the chamber floor from either end. The drone king easily shoved his fucktoy onto her back and drove his shaft into her tight rubber pussy, the toy moaning in ecstasy as the king grunted with pleasure, another jet of hot, rubbery spunk flowing from his seemingly endless reserve. Then, he flipped the pink drone onto her belly and resumed pounding her warm, rubber ass, their bodies squeaking together with each thrust. Shining Armor had more than enough fuckholes to keep Cadance's relatively short attention span and endless sexual desires pleased, as Cadance quickly tired of one hole before moving onto the next, his horny urges never diminishing.
