“This is such a shitty idea, you know that, right?” Ryan lamented as he put the uncomfortable harness around his thin body. “We don’t even know what’s down there!”

Harold just grunted, looking down into the large, dark cave that dove straight down into the unknown. They were in the middle of a deep forest that they had just spent the last few days hiking through, and this cave didn’t show up on any of their maps. In any case, Harold ignored Ryan’s complaints and instead chose to just double check of all their gear. He had to make sure they were both safe on the way down.

Ryan ground his teeth. “Seriously! Bro! Are you even listening to me?”

“No. Stop being such a baby.” He responded, eyeing their map. “It’s just a cave, no ghoulies or spooky scary skeletons. I wanna see what’s down here.”

“And you’re willing to just frolic down a creepy dark cave in the middle of nowhere?” Ryan sighed, running a tired hand through his wild black hair. “It’s creepy, and it’s a waste of time.”

“Come on, it’ll be a fun story to tell your kids.” Harold quipped. He stepped onto the edge of the gaping hole and tested the strength of the edge with his weight. It was solid rock, perfect for climbing. “This will be easy peasy.”

“Can we just wait for one minute, I’m nervous here.” Ryan admitted.

Harold sighed before sitting down next to him. “Come on, we went on this hike to make some memories. This is going to be really cool, right bro?” Harold picked a few rocks from the ground and threw them down the cave, listening for the telltale sound of them hitting the floor. Harold guessed the cavern was pretty deep, the insignificant sound of a pebble hitting water almost being lost to the weak breeze.

Ryan sigh. “Yeah, yeah, sure. It's not my fault that giant, mysterious, pitch black caves appear a bit unsettling to me.”

Harold rolls his eyes. “We have flashlights.”

Ryan sighs and gets back to his feet. “Must be nice, not being scared of anything.”

“Comes with age I guess,” Harold replied as he got to his feet as well. Standing next to his brother, it was obvious Harold was the older one. Reaching six feet tall and built like a tank, he looked almost a generation older than Ryan, even though they were barely two years apart.

“Whatever.” Ryan dismissed the notion and started to stretch his limbs. “Let’s just get this over with.” Harold nodded and attached their lines to a massive nearby boulder, tying the various knots and pulleys tight to ensure it would hold their weights.

Ryan peeked over with curiosity, baffled at the huge collection of rope. His brother had always been the outdoors type and had a knack for adventure. This entire forest hike was all his idea. Ryan on the other hand was the type who much preferred to stay at home and play video games. Hiking and exploring always just sounded so exhausting. But still, once a year he indulged his older brother and went out with him on one of his ‘adventures’.

“Ready?”

“As ready as I’ll ever be,” Ryan gulped.

Harold handed Ryan a yellow helmet and put on his own, testing the flashlight strapped to the front by flicking it on and off and checking the fixtures. Ryan copied him in an attempt to look professional. They walked to the edge of the fissure and paled at the scale of the cave. The darkness descended far beyond the reach of their small headlamps.

“Are you sure about this?”

“Don’t worry, there’s more rope than we’d ever need.”

“That isn’t what I was asking.”

“I know.”

Ryan scowled and rolled his eyes. They both clambered down onto their hands and knees and started to lower their bodies over the edge. They both quickly found some makeshift foot holes, and felt their lines get tight as they started to support their weight on them. So far so good, now all they had to do was feed their lines to descend.

They both looked at each other before they began. They said nothing, but Ryan could tell from his brother’s face that Harold was excited for this. Ryan’s own face was showing emotions closer to terror and worry, but there was no turning back now. With a curt nod they both slowly began to make their way down. The depths below them remained the darkest of dark, and the cave’s changing angle meant that the sunlight above was rather quickly cut off.

Ryan’s heart pounded in his chest as he paused his descent and looked around. He was in utter blackness now. He never really liked the dark, even less so when there was a fatal drop waiting to gobble him up like a scared child. He swallowed his saliva and scratching his sweaty chest; his brother was close by, there was nothing to worry about.

Down and down they went, neither of them talking as they focused on making their way down safely. Finally, Ryan couldn’t take it anymore and he spoke, “H-how far down do you think we are?” Ryan looked in all directions, hoping his headlamp would reveal something of note, but there was nothing but smooth stone and utter blackness in all directions.

“We’re pretty damn far, I’m sure we’ll hit the bottom soon.” Harold’s voice echoed, bouncing off the enclosed walls. Ryan smiled with relief; his legs were starting to hurt and he had slowed his descent down in order to catch his breath. Meanwhile, Harold of course was in his stride. He was bouncing downwards like an olympic athlete, leaving his younger brother further and further above him.

The gap between them widened as their descent went deeper and deeper. Ryan had been pausing and shining his light down onto Harold to ensure they stayed close, but he was struggling to see him. A moment later the gap widened ever further, and Harold was so far below Ryan that he disappeared entirely from Ryan's vision. Panic flared inside Ryan, he desperately wanted to be back with his brother, the guy who knew how to handle things and who was always watching out for Ryan.

Ryan’s panic interrupted by the sound of boots hitting a floor far below him. He paused as it echoed upwards towards the cave entrance so far away. Harold must have reached the bottom! “Harold, you made it! Awesome, I’m almost there!” Ryan quickened his pace, now confident that this scary cave had an end, and they weren’t just tunneling into hell. It would be great to be at the bottom with Harold, and that meant they were that much closer to leaving this damned hole.

However, Ryan’s relief began to fade as a minute or so passed and he realized he was in silence. How come his brother hadn’t said anything when he got to the bottom? Ryan licked his lips nervously. “Harold...?” Ryan remained motionless as he heard his voice bounce off the cold, wet walls. Once his voice faded, there was no sound at all coming from below.

Ryan’s began to panic more, and he pulled his rope slack, speeding beyond what his brother would consider safe. But it didn’t matter; his brother could be in trouble! Maybe he was injured, maimed or possibly dead! The wall he was sliding down soon gave way to a large open cavern, forcing him to lower himself on the rope freely without a guide. He began looking around for a landing spot, and soon lowered himself to the floor.

The noise of his boots landing echoed loudly off the cave walls, and he once again called out. “Harold?” He untied his ropes and swung his head in a frantic search for his brother. There was neither hide nor hair. The cavern floor itself was void of any trace of his brother, the only evidence that Harold landed was his brother’s rope. It hung limply a few steps away. Ryan walked over to inspect it, and he immediately started to panic. The end of it was split, and frayed at an sharp angle. Harold didn't untie his rope, he cut it, and in a hurry. But why? Harold must have been in a rush get away from where he landed. Why? What happened?!

“Harold!?” Ryan screamed again, squinting into the massive, smooth cavern for somewhere his brother may have ran too. There were a few holes in the walls across the cavern, maybe his brother ran over there, but again, that begs the question as to why. Ryan cleared his throat and cupped his hands around his mouth “H-harold? This isn’t funny!” His voice wove its way down into the caves, but he received no response.

“HAROLD!” Louder this time.

Ryan shook in fear. He couldn’t go back without his brother. He looked forlornly at the ropes leading up to safety, before dragging his feet and slowly shuffling towards the tunnels leading deeper into the cave. His headlamp did next to nothing in the oppressive darkness, it was only enough to show him where he was stepping.

Deeper and deeper the caverns went, and Ryan trecked on and on. After an hour, he began to question his judgement. Even if he found his brother, would they be able to find the way back to their ropes? But what choice did he have? Leave without his brother? Even if he got back to the surface, they were a two day trek from the nearest settlement, and there’s no way he would be able to find this cave again if he left to get help.

Weary from fear, and from walking so far, Ryan sank to his knees and leaned against a cavern wall. It was trickling with water and Ryan cupped his hands to gather some to clean his sweaty face. The cool sensation refreshed him for a few seconds, but then he remembered his situation and the fear returned. Ryan sighed and got back up, deciding to once shout his brother’s name out into the darkness. There was no response though, and Ryan's chin began to tremble. Every time he called out and didn't get a reply, it was another blow to his dwindling hope that he would ever see his brother again.

The cave continued for miles, and Ryan hadn’t rested for hours, but it’s not like he really had a choice. A paltry banana was all he had in his bag, and he ate that hours ago. He devoured it with reckless abandon, but was left hungry after it was said and done. That hunger and fatigue only increased as he moved deeper and deeper into the bowels of the cave. He knew he was going to pass out soon, but he crawled on. He kept going in the hope that his brother would be there to help, to tell him that everything was okay.

But everything was so dark now.

...

A whisper.

Not noticed in the noise of everyday life, but to him, in this silence, he heard it. It was telling him how to act, what to do. It told him of conquest, extraordinary things that couldn’t be understood without sight. And then, in a singular moment, it stopped.

Ryan shook off his fatigue and opened his eyes, looking for the source of that whisper. Was he asleep? He didn’t even recognize the cave he was in anymore, his mind had started to crumble under the fatigue miles ago and had just been moving forward on autopilot. Where was that whisper coming from? And where... where was he?

Ryan looked around in a mixture of awe and confusion. He had entered an almost perfectly circular, smooth cavern. In the center, before his gaze was a pillar, tall and black. A shrine to something long lost and forgotten. Radiant crystals adorned the walls, bathing the room in a sickly green glow. It reminded him of... home.

Wait, what? Ryan shook his head. Foreign memories filled his thoughts, of things regretted, abandoned and hurt. They conflicted with him. Was this delirium talking? Stress and fatigue? Or, no, the thoughts were a new part of himself. He belonged here, with them. He should just accept them.

So he did.

This shrine was important. A tool of worship. Something he should investigate?

He shakily took a few steps towards it, trying to remember where he was.

“Touch it.” Came the voice, much clearer now.

“Why?” He spoke, his eyes struggling to stay focused and his body swaying with fatigue.

“You can be strong, you can rise above the rest, you can help your brother; no longer a burden to him.”

“I’m not a burden!” He mumbled as he paced up the steps leading to the shrine, stomping out his frustration onto the hard floor. The closer he got to the monolith, the clearer that voice got. It was a strange voice, something in his head that he knew wasn't his. Memories began to flood his mind. It felt as though the voice was browsing his memories and bringing old things to light. Actions he’d long since accepted and regretted, things he could have done differently. Maybe he was just dying and this was his life flashing before his eyes?

The monolith was before him now. He reached out a hand, but did not touch its surface. Engravings of strange creatures, battling and dancing, intertwined with words and symbols that radiated power. It made his hair stand on end and his heart beat faster. Even in his delirium, his body was trying to warn him to back away.

“TOUCH IT!” The voice screamed, untold fury in it’s voice. Ryan stared blankly ahead, then slowly pushed his hand forward until he felt the cool, smooth surface of the monolith on his skin. For a moment, he was almost disappointed that nothing happened, but then a searing pain struck his arm.

He fell backwards onto the floor, twitching madly as pins assaulted his tired body. His eyes glazed over as a perverse sensation pierced his mind, flooding it with unlearnt knowledge. He let out a feral screech as his body contorted and snapped, bones and muscle and sinew becoming malleable. All he could think of was pain; flashes of green blanked his vision as he clawed desperately at the floor.

The smell of burning flesh entered his nostrils as charred holes burnt right through through his arms and legs, sealing themselves and leaving gaping holes which flesh and bone once filled. His clothes fell limply from his scarred body. His hair began to fall like rain, gathering underneath his twitching body, new hair, like seaweed began to sprout from his skull.

His finger shattered and snapped until they were nothing but mush, what remained of his hands hardened and began to blunt themselves, leaving large black hooves behind. His chest compressed into a barrel, crushing organs and causing him to cough new green blood onto the ground. He hacked and wheezed as his organs were torn from their usual position and re-arranged to fit his new form.

The skin around his stomach thinned, becoming green and transparent; giving the world before him a view into his sickening inner anatomy. The rest of his skin was blackened rapidly, it too changing into something hard and alien. His skull cracked open and splintered as it extended outwards into a muzzle, and he let out a savage cry of agony as a wicked horn erupted from his destroyed skull.

New organs formed. A special gland that secreted a moldable green ichor replaced his usual saliva glands. And new pheromone pores opened around his body, allowing him to control his victim’s emotions.

His eyes melted away, the blue pools dissolving leaving only the whites. But they were quickly replaced as green eyes, slitted with sinister intent replaced them. His reproductive organs pulled upwards into his body, the form and function being changed to something more fitting of an vile insect. A new womb was formed, not for holding young but to mass produce insertable eggs. His penis morphed too, long and green with a wide urethra, perfect for spearing reproductive prey.

Finally his spine snapped, ceasing his movement. It shrunk and bent, preventing him from walking on two legs ever again. In a moment of clarity, his wild eyes widened in panic as he realized he was reduced to nothing more than an animal. Deceptively strong wings busted from underneath his new chitin, they flapped with blinding speed to fling away the blood stuck to them.

A mournful wail broke from his mouth, smoother and more feminine than before. His entire body remained in agony, throbbing with a dull ache that sent goose bumps underneath his new shell. She sobbed pitifully for several minutes. She was broken.

The whisper in his head offered him no words of comfort or encouragement for enduring the painful transformation. The whisper didn’t care, it already got what it wanted. Now it just has to seal the fate.

John shaky lifted a hoof, prodding and poking herself. Wincing at the alien sensations they created. Her wings hung limply at her sides, and she began to cry. She was a monster, a creature straight from hell itself. He was a grotesque beast, one that John didn’t even want his name associated with anymore.

“...He did this.” The whisper finally hissed into her ear. She jumped slightly at the sound, and the voice continued. “He brought you down here. He abandoned you. He left you to die!”

“N-no.”

“Yes! It’s his fault, always dragging you along like a child! He’s always right, he’s the favorite, and he’s handsome and strong! It was his idea to come down here! You followed along like a LOST PUPPY!” It screeched.

“Please don’t…” The creature pleaded.

“You’re weak. No wonder he abandoned you, the burden, the annoying little blotch on his successful life that just won’t go away!”

Her cries for mercy went unheard as vile thoughts hammered her mind, teasing her, telling her how useless she was. They continued endlessly and came from inside her own head, twisting her thoughts.

Her inner anguish was replaced with apathy... then conformed to acceptance.

“You’re... right.” She slowly admitted with a sniffle. “I’m useless, it’s no wonder he left me down here. He made me into this to get rid of me.”

The whisper poked her a little bit further. “You don’t have to be useless anymore. Now you are powerful, the grace and beauty of a true queen!”

“A queen?” The changeling mumbled, staring at her feral hooves. “I’m a monster.”

“Of sorts, but you are still a queen! All the people of this world will fall to your hooves. For you are the true ruler of this world now.”

Chrysalis stared at her hooves, turning them over and inspecting them, feeling the power her body now possessed. The form which she had considered horrifying only moments ago took on a new light. She saw the untapped, restrained power which flowed through her. She saw her vile, feral appearance that could somehow magically entrance any male. And most importantly, she saw somebody... fit to rule.

A crooked smile spread across her new muzzle, and she decided to let the whisper take a permanent place deep within her twisting, vengeful brain. They would become one, and it would guide her.

“We need subjects.”

“Make some.”

Harold was not having a good day. He should have listened to his little brother and never went down into the damned hole. He looked down at the stone pinning his leg and winced at the pressure still pinching him.

“Bloody rock.” He grumbled, having long since given up on trying to escape. He had opted to wait for his brother to find him; the tunnel only went one way after all. It was his paranoia that caused him all this mess. When he had roped down here, all those hours ago, he very quickly became terrified. He thought he saw something. Blue eyes watching from the darkness? Rubbish. How could he have been so stupid? How could he have panicked, cut his rope, and run away from some hallucination of his? He never even called up to his brother to tell him what he saw, he just stupidly ran out of fear. He ran right around a dark corner and over this rocky terrain without looking where he was stepping. That’s when he screwed up and ran over a deep crack in the stone ground. His foot wedged itself deep in the tight crevice and got stuck. With his foot suddenly stuck in place, and in the middle of a panicked sprint, his momentum caused him to face plant. He fell hard, and he hit his head on the rocks knocking himself out cold. He woke up an hour or so later, only to realize his brother had wandered off deeper into the cave to find him.

Harold sighed and tried to move his foot again, but it was painfully pinched in the crevice and it felt like his ankle may be broken. There was no way he was getting out of here without help. Well, at least his brother should be able to find him, Harold was pretty close to the ropes leading out of here. His little brother should circle back to this place soon, and then Harold will be able to call out to him. Bah, if only he had stayed closer to his brother in the descent instead of diving down here at a faster pace. If they had been together, then he wouldn’t have got spooked by his hallucinations and gotten them both in this mess.

He could still see his hallucinations here and there. Blue eyes... watching him from the darkness. He didn’t pay them any mind though, they were clearly just his mind playing tricks on him after spending so long in this dark cave. He wasn’t scared of them, but he was scared for what he heard all of a sudden: A feminine, haunting laughter that echoed off the walls.

Harold’s heart rate rocketed and he lay backwards, attempting to lower his body profile to hide from whatever made that noise. He lay there in breathless silence, anticipating the monsters that would come and get him. He wished his brother was there, he was always the voice of reason.

He lay there still for another minute or so, and soon reasoned that the devilish laugh must have just been another hallucination. His pounding heart calmed slightly and worked up the courage to call for his brother again. “Ryan!” He shouted. “Ryan!? I’m over here! I’m stuck!”

Nothing. He groaned and lay back on the ground. Bored and incapable of doing anything until his brother found him. He couldn’t do a damn thing like this, and his phone was out of charge. Not that it would have gotten any signal out anyway, who even knew how deep into the ground they were right now. They were totally and utterly cut off from the the rest of humanity.

Suddenly, the distant sound of something rhythmically hitting the floor caught his attention. It sounded like somebody hitting two coconut halves together. He perked his ears as the tapping came closer and closer.

“Ryan?” Harold turned his headlamp back on and looked around.

It stopped, and he called out again. “Ryan, is that you?” He could hear it breathing; it was far too close for comfort. “Ryan I swear to god if you’re fucking with me!”

It giggled in response, it was definitely not Ryan. It sounded like a woman, but what would a random woman be doing all the way down here? The clopping continued getting closer still, he tugged at his leg, trying once again with all his might to get free. After a few useless tugs, he looked over the rocks once again, immediately wishing he hadn’t.

His lamp cast a sinister shadow over it, a creature that seemed to have come from hell itself. It wasn’t human, and it didn’t look like any animal he knew. It was horse shaped, but had reptilian eyes and the wings of an insect. The creature stepped closer and Harold froze in fear as his eyes took in the sight of it all. Black hooves, legs with gaping holes, a twisted set of fly wings, a greenish window into her internal organs, and an evil grin to top it off.

Harold screamed and ducked back down, laying flat on the ground and not daring to look back up at it. He immediately reverted to the childhood mindset of ‘if I can’t see it, maybe it can’t see me.’

The reality was much, much worse. The creature trotted closer to him and bent down close to him, bringing her face right up to his. Harold opened his eyes back up and sputtered, “WH-what.” His mind preformed mental gymnastics in an attempt to grasp what he was seeing. “What the fuck!” He yelled. The monster didn’t even flinch; it just stood there, staring at him. “What are you!” He yelped.

She looked hurt for a moment. Then she snorted and began to trot circles around him, her bestial hooves highlighting the fact that she wasn’t human, at least, not anymore. She looked him up and down, investigating him like a prime piece of beef. “Aww.” She tutted. “You don’t recognize family?”

Harold’s face grew pale.

“R-Ryan?” The monster scoffed at him condescendingly.

“Of course it’s me. What did you expect?”

“What happened to you?” He asked with fear in his voice.

“Isn’t it fantastic?” Ryan beamed.

Harold couldn’t believe what he was hearing. “Are you okay? How is this possible?!”

“They fixed me Harry. I’m better off now.” It smiled.

“There was n-nothing wrong with you.”

“LIAR!” It wailed, stomping a hoof onto the floor with such force that the rock cracked under the pressure. “You cannot begin to imagine what it’s like! You were always the favorite, the perfect child, the sweet little angel who could do no wrong!”

“This isn’t you!” Harold cried.

“Of course it is. They saw what I really was; they gave me the power to take what I want. They understand me. I won’t be in your shadow any longer.” She waved a foreleg over her chitin body. “This... this is the form I love. It’s perfect, don’t you agree?”

“C’mon Ryan, we can leave, find a way to change you back!”

“Don’t call me Ryan!” She snarled. “That's not my name anymore, it only refers to my old weakness!”

“What are you talking about!?” Harold became to truly panic. “Brother, snap out of it!”

Her eyes narrowed. “We may be brothers, but you will not address me as such. I am your Queen! You shall show some respect!”

“W-we're family... brothers...” Harold's voice began to waiver.

“Family? You abandoned me! YOU COWARD! And only now are you blubbering like a petulant child and begging for my help. For so many years you did nothing but look down at me, and now you honestly expect my mercy?” She laughed a terrible, spine tingling laugh. “But don’t worry... Harold, I’d never abandon you. One of us has to be the stronger sibling after all.”

A green aura wrapped itself around the rock crevice holding his leg in place, and a moment later the stone crumbled into pebbles, freeing his trapped leg. Before Harold could celebrate, the aura quickly moved to grip Harold, holding him down with such force that he couldn’t move a muscle. The queen appraised her first subject, humming as her magic wrapped itself around his body. In the wake of everything else that transpired today, the sudden appearance of magic being used before Harold did little to shock him. Neither did he notice the flash of excitement in her green eyes.

She smiled and trotted closer towards him, the magic aura still keeping him from moving. Harold began to sweat in fear, and got a little unsettled as she just stood there and did nothing. The seconds ticked by, and it was starting to creep him out. What was she planning? The answer came a second later, and he nearly jumped out of his skin as she spat a thick globule of goo onto his chest. It rapidly hardened into a thin, transparent film. The then did it again and again, spitting her insect spittle all over his body. He couldn’t move due to the magic, so he watched in tentative fascination as she continued the process over his entire body, save for his face.

Once his body was entirely cocooned in the green chitin, she released her magic hold on him. He struggled for only a moment before realizing that he was just as paralyzed as he was before. He wasn’t going anywhere. Well, at least his face was free from the goo.

“Don’t worry.” She cooed. “We’ll be together for a long time. The voices have told me that this form is immune to the affects of aging, and it tells me how I can make those close to me share my glorious lifespan. I even have the power to create sustenance out of thin air... but I do have a need for you, my dear brother. Why, you're going to help me start my empire.” She stroked his face lovingly with a disgusting, hole filled hoof. “You see, I need subjects. And aside from you, not many people come down here, do they? How can I conquer the world if I don't have an army?”

Gathering a large wad of goo in her mouth, she suddenly spat onto his face. Harold began to panic as he felt it rapidly cover his head and merge with the rest of the cocoon. The sound of the Queen became muffled as the cocoon finished forming a perfect seal over his body.

A green liquid began to seep through into his prison. As the liquid slowly encompassed his legs and body, he desperately crawled upwards in his cocoon in an attempt to avoid drowning, but it was a fruitless effort. The liquid soon filled his entire tomb, and it invaded his nostrils and mouth. He gagged and choked on the stuff as it filled his lungs and began to change his bodily functions. The enchanted liquid went to work preparing the host for a long hibernation.

The queen stroked the cocoon lovingly, infusing it with her own magic to make the transformation happen just the way she wanted it to. Harold wouldn’t mind, he was was already in a deep sleep. The queen lifted the newly formed cocoon with her magic, and carried it with her deeper into the network of dark caves. She trotted through the darkness, going miles underground, and getting far, far away from the only entrance back to the surface.

She brought the cocoon back to where her monolith was located... and she waited.

Harold couldn’t believe what was happening. This must be some kind of fever dream or a hallucination brought on by some bad food, that had to be it. But those reasonings provided him little comfort, his assurances and denial fading in the face of the moldy green surface that covered his vision. This was real, he was trapped.

His body was numb due to the effects of the slime; it provided everything he needed to survive for years. He hasn’t been in here that long though... has he? He had no idea, time didn’t seem to apply to whatever this hell he was in. All he knew was he was trapped. He had tried, several times, to break out of his prison. He pushed against the outside with all his strength, but it only caused to cocoon to bend outwards slightly before springing back into place.

It was a horrifying sensation, having his lungs filled with a viscous liquid and breathing it in every few seconds. It felt like he was drowning, but at the same time he wouldn’t. Every so often his body attempted to reject the goo, causing him to spasm in agony as the muscles in his body worked overtime to push it out.

He didn’t notice as his clothes began to dissolve away, leaving him nude. His body hair soon followed, leaving him as hairless as a newborn child. The chamber had a lot of mass to work with; it did not need little details like body hair to complete its work. In the same manner, his muscle mass was also marked for removal. His new form would not much muscle on the limbs. No, his new form was going to only be used for more... intimate tasks.

Harold eventually fell into a dreamless sleep as the cocoon assaulted his inner biology. It began rearranging DNA to create new hormones and acids more suiting to his new purpose. His skin bulged and ripped as deep blue fur grew out, a white mane sprouting from his bald head, his eyes turning a deep green.

A savage cracking sound signaled his bone structure beginning to change, much like his brother. His legs shifted upwards, and his feet elongated as they repositioned to walk on hooves. His his arms moved forwards, preventing him from standing straight. His skull shattered into little pieces, before reforming like a puzzle into a muzzle.

His nails merged together to form thick hooves, the fur covering them as fetlocks. A tail grew out from his extended spinal cord. His midsection collapsed in on itself, forming a stubby barrel. His balls and penis dissolved away, and it’s in place were thick, black, equine pussy lips that opened into his new womb. His womb was much, much larger than the average mare, a deliberate choice made by the cocoon.

Eventually the mind numbing effects of the pod wore off and Harold woke up to gaze down upon his new body with horror. How was this possible? He’d been changed into some sort of animal... some sort of... pony? He looked around at his body and saw cute hooves, fur, and a fluffy mane. At least he wasn’t an insect beast like his brother had become. But why was he a pony? He bashed his new hooves against the pod to little effect. He had to get out of here! He had to escape and get away from that crazy bug!

Just then, the cocoon suddenly split open, spilling the slime he was suspended in. He fell forward and let out a gargled scream. He coughed and heaved to expel to slime from his poor lungs. For half a moment he thought he was free, but then he heard clopping as his younger brother slowly came towards him. Harold tried to get away, falling backwards, clumsily using his new limbs to try and propel himself away while still wearing half of the cocoon.

A tight magic grip took hold of him, stopping him dead in his tracks. He wailed and thrashed. The queen only giggled in response, then tenderly used her magic to remove the rest of the cocoon and strip away the leftover goo from the fur of her newest creation.

Harold cracked open his eyes, looking over at the monster than was his brother. She had a predatory look in her eyes as she spoke to him. “You came out beautifully, my brother. Perfect really. One arousing creation if I do say so myself. And one with nice, wide hips...” She stopped and sniffed him like a dog. “...and a fertile womb for my eggs to grow.”

“W-what do you want me for!” She whimpered in a new, feminine voice, only now realizing that she has been made into a female.

“Isn’t it obvious? What kind of Queen would I be without subjects? You’re going to help me.” She waltzed over, swinging her hips in an exaggerated manner. She leant down, taking a big whiff of her consort’s chest fur, rubbing her face over it like a cat.

The Queen moaned as she took in her new subject’s scent, she’d make for a perfect broodmare. The sight of her new consort acted as a potent aphrodisiac for the Queen, and a green phallus stretched its way out of her vagina. It was a feeling she couldn’t put into words, and she had all but forgotten she used to be a human male with a cock of his own. This one was different though, it was especially large, even for an horse of her size. It was designed to allow easy passage of eggs into an accepting womb.

“G-get away from me!” Harold struggled against the stronger mare, screaming at the sight of the Queen’s large cock.

“Don’t worry dear subject, we’re going to know each other very, very well.”

Chrysalis licked her lips as she got in position, forcing Harold to lie on her back as Chrysalis lined up her large maleness with the tight, onyx cunt before her. Harold wiggled in an attempt to put off her aim, but the magic holding her only tightened in response. As one last futile effort, she screamed for help.

Chrysalis smirked “We are miles underground, deep within my new personal hive. No one is here to save you. But don’t worry, you’ll beg me for this... eventually.”

Showing little concern for her former brother’s comfort, she quickly lined herself up and eased herself in.

“Ahh! Stop! Stop!”

Her walls were crushingly tight, massaging the huge length of the Queen. She panted in pleasure as her medial ring passed the taut black lips. The virgin cunt was being stretched to its very limit.

“O-Oh god, p-please stop!”

“You-you are very tight subject!” She moaned.

She pushed onwards, cramming her entire cock into the virginal mare. Her flared head batted at the entrance to her receptive and fertile womb.

“Look into my eyes.” She commanded. Not wanting to face further punishment, Harold complied with the creature that was taking her. As their eyes locked, the Queen’s eyes flashed rapidly in green, almost like morse code.

Harold's eyes became entranced and her optic nerves sent the command to her brain. Her vision blurred into a range of greens and blues as she felt herself start to fully relax. For that moment in time, the only thing that mattered in the universe was her queen. She must... pleasure her queen. Harold relaxed further and felt her tight cunt grow wet. Her sopping walls dripped with endless juices as her body did everything it could to make her oversized Queen better able to fuck her.

“Good.” Chrysalis hissed. The Queen rocked back and forth inside her new toy, but the position didn’t feel right. This was how humans liked to mate, and it didn’t suit her new form. Using her magic, Chrysalis flipped the mare rightside up and had her stand up on her hooves. Harold, in a daze, flicked his tail to the side in order to please his Queen. Chrysalis just snorted and climbed on her back, mounting her like a real stallion.

“Perfect.” She plunged her oversized cock back into Harold and began to speed up, ignoring the moans of her servant. It was nearly too tight for her to move, but she soon found a rhythm that allowed her to pound away at a frantic pace. Harold drooled onto the floor, her former resistance to being taken by his Queen were melting away under the waves of pleasure.

Harold moaned as her winking clit hammered the top of the Queen’s cock, sending an electric sensation up and down her spine. They both soon found themselves unable to verbalize what they were feeling. Words simply were were not needed, and they were content to stick to grunts and short neighs instead. The Queen had descended into mindless rutting, a deep-seated instinct taking over her higher brain function. All she wanted to do was plant her eggs, to inseminate this fertile mare like the animal she was.

Harold gone almost completely numb; her Queen’s cock had stretched her cunt beyond the norm. No other stallion could possibly please her anymore, she probably wouldn’t even feel them. Her mind wandered for a moment. Wait... she used to enjoy the fantasy of eager stallions rutting her cunt, right? She always wanted to be mounted and pumped full of seed? Harold stared off into the distance as the matting with Chrysalis went on. Yeah... she’s pretty sure that was always her dream, she always loved being rutting. Sadly no normal stallion would probably mate with her after this since she’ll be so loose. But that’s okay, her Queen was here! She’ll rut Harold whenever she’s wants to.

They continued on, ignorant to their surroundings. Both reduced to their basic instincts, fucking like animals. Chrysalis wanted to spread to seed, and Harold was rapidly becoming content to be reduced to a worthless cumdumpster for beasts. She would be used for the Queen’s pleasure, she would become bloated with her children, and would breed thousands of loyal subjects.

Both soon reached a climax. Harold screamed as her muscles clenched and tensed as an orgasm rocked through her, splattering both of their lower bodies with mare cum. The sudden increase in pressure caused her Queen to grunt, before moaning as she came. Harold was disappointed at the lack of cream filling her.

The Queen grunted again, her flare expanding in the small space provided and her urethra opening wide. Harold’s eyes widened as he felt the huge cock expand even further, a bulge passing down as her muscles pulled it inwards. Her womb was wide open, prepared to accept the eggs. She could no longer move, the strength drained from her body. She could only shake in terror as the first egg emerged from her Queen’s cock, dropping into the large uterus.

The unnatural feeling sent shivers up her spine. The queen sighed and wrapped her hooves around Harold’s mid-section, hugging her as she continued to pump egg after egg into her un-protected and abused cunt. Soon Harold felt so full she was nearly bursting, her womb had just accepted twelve grapefruit sized eggs. It left a funny feeling weight on her lower body; she could only imagine what it would feel like if she tried to walk.

The Queen purred and nuzzled her neck. “Good girl.” She cooed, running a hoof through her mane. “Our children will amazing.” Harold could only stare at the opposite wall in quiet horror. Did he just get impregnated by his brother? Harold shook her head. No, wait, there is no brother here, Chrysalis is her Queen. Harold found herself smiling and nuzzling her master. She was truly the most fortunate of all ponies, being this close to the Queen.

It had been many days since their first mating. Still in the same chamber they sat, deep underground, far, far away from any distant humans ever finding their hive. The monolith in the center of the room has been moved away to make room for a jagged black throne, upon which Queen Chrysalis now sat.

Chrysalis sighed at the happy memories, shedding her pathetic, human body and letting her former brother join her in the glory of their new hive. She giggled as she felt the bloated mare in her lap twist and moan, affectionately stroking the pony’s swollen stomach. Ever since their first night, it had become an addiction of Harold’s to fall asleep with a nice, fat cock stuck inside her cunt, even though she was already pregnant. Chrysalis smirked, she didn’t owe this the broodmare anything and could just as easily force her to sleep on the floor... but it amused her greatly to see this mare so completely dependent on her cock.

A few moments later, Harold stirred in her sleep. She looked up at her Queen and smiled, then nuzzled her face into her Queen chest. The Queen stroked her consort’s mane for a few moments, and then Harold gasped as she felt a rumble in her stomach. A moment later there was a sudden flood of water.

“It’s time!” Harold squealed happily.

Chrysalis smiled and laid her down gently. She had been looking forward to the birthing of the mature eggs for quite some time. Harold spread her legs spread wide open and Chrysalis patted her gently. “Push!”

Harold grunted and pushed, her strong vaginal muscles working to bring the much larger eggs from her womb. They had grown massively in size inside her fertile womb, and she was happy to be such an important part of the egg laying process. The green changeling eggs were now larger than melons in size, and they began to emerge from her massive cunt one at a time.

Harold’s custom-made form made the birthing process mostly painless. It made sense to Harold, she figured all cute ponies like herself were made solely to breed endlessly by their Queen. As the massive eggs were pushed out of her, she felt her wet pussy get stretched open to an obscene size. She grimaced slightly, it wasn't that painful, but she knew her cunt would end the day even looser than it was. In any case, it was a price she was more than willing to pay to be her Queen's consort.

One by one they popped out, Chrysalis carefully laying them out nearby. Tears of sadness welled up in the broodmare’s eyes as she finally released the final egg from her warm insides. Not because she had given birth, but because she was no longer pregnant. She hated being without eggs inside of her. She needed them, she had to be pregnant at all times. And the potent changeling hormones flooding her veins made sure she was conditioned to always think that.

The eggs were matured now, but they would not hatch for several more days, as they still had one last leg of development to cover. They would soon give rise to twelves adolescent drones, ready to do the absolute bidding of their master. Chrysalis grinned, now she really was a queen. She was powerful and growing more so, but she still has to bide her time for now and wait for her armies to grow before she could show the world her true power. It would take time, which she had. But for now, she had other things to do around here.

She looked towards the downtrodden broodmare, who was sniffling as it rubbed it's empty belly. Chrysalis knew Harold was missing the eggs inside of her already. Chrysalis smirked and walked up to her, wiping the tears off Harold’s cheeks and walking around to her rear.

“Don’t cry, I need you for something...” Chrysalis licked Harold’s loose cunt.

“More?!” Harold’s eyes sparkled with happiness at the thought of being fucked so soon.

Chrysalis grunted as she mounted her broodmare once more, the loose cunt fitting quite perfectly over Chrysalis’s massively oversized cock. Chrysalis thrust herself in deeper, and bent down to whisper to her mare. “More? My dear little pony we only have twelve children. We will need many hundreds, nay, many thousands more.”

The squeal of happiness that followed was so loud it was heard for miles in every direction. There was no one to hear it though, just mile after mile of vast, undiscovered caverns. Caverns that the new Queen fully intended to soon be using.
