[NSFW] - Korumaru Conversion Rough Draft

 

"What even was that thing?" Dash's eyes interrogated the cave entrance, but the darkness held it's secrets close. Shadows shifted and stirred, but none made a sound.

"I'm not entirely sure," Twilight said, brow furrowed in concentration as her horn steadily pulsed with magic. "It's essence is fading over time. I'm not sure if it's actively supressing it, something's muffling it, or it's just getting further away."

 

Dash flicked her tail and let out an aggravated sigh, before she jumped onto her hooves. "Well we're gonna lose it if we keep sitting on our flanks! Let's go after it already!"

 

"Rainbow Dash, you can't always just dive into these situations and hope everything works out okay!" Twilight punctuated her statement with a stomp on the ground. She turned to look Dash in the eye. "We have no clue what this thing is, what it's capable of, what it wants, or what it was even doing. There's too many unknowns!"

 

Dash rolled her eyes and walked towards the cave entrance. "It was some black orb with an eye, it can probably only float and watch, we don't know why it was watching Ponyville from the Everfree, and it was obviously checking us out for some reason." Dash paused next to Twilight and flicked her horn with one of her wings. "And it's not like you're gonna find out anything else now that you've dropped the spell. I doubt you could even find it again from here. So let's go!"

 

Twilight's eyes flicked up to her horn. Yes, she did drop the spell at some point. Her fance scrunched up in annoyance. "Well maybe I wouldn't have needed to cast the spell here if /someone/ wasn't distracting me the whole time we were tracking it."

 

Rainbiw Dash rolled her eyes. "Well if it wasn't for me urging you along, you would've lost the thing a long time ago! Thanks to me, we know where it's secret base is!"

 

Twilight's face twitched, venom leaking through. "Yeah, but now we're sitting in front of it's lair with zero knowledge of it whatsoever. I wouldn't have dropped the spell if /someone/ wasn't arguing with me while I was trying to fix our near-total information blackout!"

 

Dash's face twitched. "Hey, it's not my fault that we-"

 

Twilight jammed her hoof into Dash's mouth, cutting her short. She glared at her from the side. "Congratulations, you win. We're heading into the cave. No point in arguing any further." Twilight shuffled forward begrudginly, muttering under her breath. Dash smirked and pumped her hoof in excitement. A near-silent "yesss" slipped out before she flew forwards to catch up with Twilight as they entered the realm of the unknown.

 

 

Twilight's horn glowed a comforting purple light. The only safe haven in the ocean of dark and stone. The two mares made their way deeper into the cave, the light from the outside having faded long ago. The unicorn trotted on the ground in front, her magic lighting the way. The pegasus hovered in the air behind her, eyes and ears scanning the shadows.

 

 

"Twilight!" Dash whispered fiercely.

Twilight froze immediately, scanning her surroundings. Her brow furrowed in confusion. She turned towards Dash, and right as she was about to open her mouth, she noticed Dash hovering in place and staring coldly into the distance. Twilight turned back around and peered into the darkness where Dash was staring. Her eyes went wide and a shiver ran down her spine.

 

 

Barely visible in the darkness, a single purple eye staring straight at her. Twilight started to breath faster as she stared the eye down. That's when she noticed that the eye wasn't looking directly at her. It was looking slightly above her eyes. At her horn. Twilight blinked. The eye blinked back. Twilight pushed a little more magic into her light spell. The eye narrowed, almost as if it was squinting. Twilight cut off some of the magic flowing into it, dimming the light spell. The eye blended into the darkness more, but widened slightly.

 

"Rainbow Dash, you still see it?"

 

"Yeah, haven't taken my eyes off of that thing since it showed up."

 

"Good, let me know if it does anything."

 

Twilight sat down and set her saddlebags to the side. She broke eye contact with it, then looked back. No change. She blinked. It blinked back. Twilight opened up her saddlebag and pulled out a small crystal attached to a necklace. She stood back up and made eye contact with the creature again. No change. Twilight brought the crystal up to her horn and pushed magical energy through it. The crystal began to glow a dim light. She walked over to Dash and placed it in her hooves.

 

 

"This should last you about 4 hours. If something goes wrong, that should be plenty of time to get out of the cave and go get help."

 

"You're not planning on doing something stupid, are you?"

 

"No, this is research! I think it's avoiding my light. I want to run a little experiment to test my hypothesis."

 

"What kind of 'experiment'?"

 

"I'm gonna cut the power to my light spell for three seconds, then I'm gonna flash it back on. Be prepared just in case it tries something."

 

"Don't worry, I got your back."

 

 

Twilight took a deep breath and stepped forwards a few paces. She blinked. The eye in the darkness blinked back. Then her light vanished.

One.

Two.

Three.

Twilight surged power into her horn. Light burst forth like the first rays of sunlight over the horizon. Her light pierced into the darkness and smashed into a floating orb of black a pony's length away from her. The orb sizzled and rippled. Teeth erupted from the orb as an inhuman screech echoed in the cave. Twilight leapt back, shock etched across her face. She stumbled and nearly fell. However, the light spell did fall. Darkness shrouded the mares once again. Twilight panicked and cast the light spell again. The orb was on top of her, teeth bared wide. Then everything went black.

 

 

 

Twilight jerked awake. Her hooves clattered against the ground, yet the ground absorbed the attacks like a sponge. Twilight's heart raced as she pulled herself up. Something was wrong. Her face felt flush, her hooves shaky, and her flanks twitchy. She wanted some big stallion to slide up behind her, wrap his forehooves around her, pull himself up, and... Okay, what's going on? Twilight shoved the fantasy down inside of her. She could still feel it squirming, but at least she could think. She quickly scanned her memory and recounted the steps that brought her here. Wherever here was, that is. The cave was different now. Instead of granite the cave was coated in some kind of shiny black substance. Ambient pink light faintly trickled across the area, although Twilight couldn't pinpoint an explicit source. The light diffused through a lazily-drifting pink gas. As she discovered earlier, the material coating the walls was not hard. It had some give. If she pressed her full weight into it, her hoof sank halfway up her fetlock. As she did, she discovered something that sent her mind spinning. The cave was alive. Beneath her hooves she could feel the cave pulsating and squirming. Twilight jerked her hoof away.

 

 

As she did a large burst of pink gas erupted from it, spraying her directly in the face. Twilight jumped backwards away from the gas, but not before breathing some in. It sent her head spinning, horniness clawing it's way out from the pit she shoved it into. Twilight shook her head to clear her thoughts and tried to take deep breaths to calm herself. This only sent more of the gas into her system. She could feel herself get wet from arousal. Frustration mounted from the unnatural horniness spreading through her system. Twilight took a wide stance and sent a surge of magic into her horn. In return, she felt a surge of electric pleasure pulse back down. Her knees buckled from the unexpected stimulation, her eyes rolled up into the back of her head, and she collapsed on the ground. Twilight reflexively cut the flow of magic when she felt something unexpected, and the pleasure soon faded. What the buck just happened? Her horn felt... weird. Glancing up at it, unease and concern dominated her thoughts. On the tip of her horn sat a splotch of black latex, a similar material to the cave walls. This one pulsated pink light. Perhaps from the magical energy she pumped into it. When did that get there? She didn't remember ever scraping it against the floor. Did the orb that captured her do this to her while she was unconscious? Why did it stop with just a small splotch of goo on her horn? Why didn't it do anything further? She was completely and utterly defenseless, why do something so miniscule? Beyond the glow that she's certain wasn't there before, she could feel it writhing and squirming. Did it move when she pumped magic into it?

 

 

Twilight didn't know whether it was her natural curiosity or the unnatural horniness compelling her, but she sent an experimental burst of magic into her horn. Electric pleasure jolted down her spine once again, her horn the lightningrod for it. Her body spasmed and bucked. This time, Twilight had the discipline to keep her eyes on her horn. As magic pulsed into it, the goo writhed faster and the glow became more pronounced. Then something happened she didn't expect. It expanded. Tendrils of black surged down the grooves of her horn, taking root in them. Her eyes fluttered from the sensations. Twi panicked and cut the magic to her horn. However, the goo didn't stop moving. Once it had taken over her horn, it started to expand on the other end. The goo swelled on her tip before it dripped down into a ball shape. The goo disconnected, forming a perfectly round sphere floating in mid-air. No eyes or teeth on this one, but it wasn't inanimate by any means.

 

 

The latex orb floated to her chest, closed it's eye, and then pushed forwards. Twilight arched her back as the nerves in her chest exploded in pleasure. The latex felt cool to the touch, but despite this, it felt alive. It wrapped around her tufts of fur and enveloped them before pressing down into her skin. Sensations exploded across her chest as it spread. Eventually it came to a standstill. It had coated the front of Twilight's chest, but could spread no further. Twilight's logical mind raced to piece together the chain of events. First she pumped magic into the latex goo on her horn. Then the goo formed an orb that expanded across her chest. The orb gave her indescribable amounts of pleasure as it did. It expanded until it ran out of goo. The pleasurable sensations were indescribable. In that moment there was only one thing that mattered. Twilight wanted... no, she needed more. The next step was clear.

 

 

Twilight opened the floodgates in her horn and magical energy poured out. In turn, the goo poured out more and more latex. Orbs appeared en-masse, spawned from her horn, and circled her. One by one they found an open portion and pressed themselves into her. They coated her flanks, her legs, her neck, her sides, /everywhere/. One even pressed itself under her tail and coated her genitals. She could feel the living latex as it slipped inside of her and lit her sensitive erogenous zones on fire. Yet another pressed even further in, lighting up the walls of her womb with an unearthly pleasure. Moans slipped out, but she was too far gone to even register them, let alone care. Her eyes glazed over as she drowned in latex.

 

 

Twilight laid on the floor in a puddle of her own fluids. Her body still twitched and spasmed as her second skin of latex shifted and squirmed, each motion as explosively pleasurable as the last. Exhausted, she looked down at herself with a faint curiosity. Her body shone black, faintly reflecting the trace amounts of ambient pink light in the cave. Her legs were covered in a similar material, though they were colored pink instead of black. Except for her hooves, which had a set of black horseshoes attached. Her mane and tail were coated in pink as well, albiet with a black stripe where her usual ones were. Twi tried to press a hoof up to her face to feel her skin, but could only feel the latex surrounding her hoof.

 

 

Her mind still spun from the insane amounts of pleasure that floated through her system. The magical flow in her horn had long since slowed from a torrent, to a trickle, and then eventually stopped altogether. Completely exhausted, both physically and mentally, Twilight didn't have the strength to do anything. That's when she noticed the latex on her horn glowed a faint purple. Yet another orb split from it, but somehow Twilight could tell that this was different from the others. It felt as if it was bonded with her in some way. The orb opened an eye and floated towards Twilight's face. It looked deep into her eyes as she looked back into it's. Some unseen magic passed between them, and the latex coating Twilight began to come alive. At first it was just squirming and writhing against her skin, but soon it's efforts grew more coordinated. Her hooves moved of their own accord, slowly but steadily dragging themselves down to her genitals. The latex around her hind legs began to shift as well. Twi's eyes widened as she realized what was about to happen. The orb in front of her smiled.

 

Twilight's hips thrust forward as her hoof dug into herself. Twilight gasped, then let out a low moan as her aching genitals cried out in pleasure. She tried to struggle against the control of the latex, but she was helpless to stop the assault of pleasure. In the edge of her perception she felt the latex on her head shift. It gently crept across her head, like a lover tracing a finger. The sensation circled around her ears and positioned itself at the entrance. Then it dove inside. Twilight jerked upwards as the goo burrowed deeper and deeper into her head. Her mind exploded with sensations as she felt the latex reach her brain. Her thoughts swirled downwards into a whirlpool of latex. Black tendrils reached out and grasped any stray thoughts that tried to fly away. A fog settled in over her brain, only pleasure remaining.

 

Twilight's eyes refocused as the orb in front of her floated down to her eye level. The eye closed for a second, and when it opened back up it was filled with rings of pink. Twilight could feel the magic crackling in the air between them. She couldn't help but to be drawn inside. The latex coated the outside of her mind while the pink spirals infiltrated deep inside. They whispered into her ear, telling her tales of pleasure and obedience. She would never have a care in the world again, beyond pleasing her master that is. No more friends to antagonize her, only fellow servants to assist her in achieving master's goals. No more arguements, as master's word is law. No more pain, as master only brings endless pleasure. All Twilight had to do was give in. Twilight's eyes glowed pink, rings drowning her pupils and a dopey smile on her face as she made her choice.

 

Her mouth already opened from the labored breaths she'd been taking, the orb in front of her dove inside. It coated her mouth, her throat, and eventually her stomach. As it took root, new thoughts sprinkled into her mind. Images of her friends, converted into servants like her. Rarity in a latex dress bringing in new knowledge to her master. Pinkie Pie and Fluttershy coated head to hoof, luring townsponies in and then springing an ambush on them. Applejack with a swollen belly being milked for more latex. Finally, Rainbow Dash put in her place, licking Twilight's hooves as she begs to become one with them. Eventually, even she is subsumed. All of her friends serving master, drowning in pleasure. Loving each other and loving themselves. A new thought appeared in her mind. One singular word. Korumaru, the name of her master. Twilight rolled it over her tongue. It felt... right. It felt /good/.

 

Twilight smiled as she lifted herself off the ground. Her and the latex coating her moved in perfect unison, guiding them towards the entrance of the cave. She had one thought in her mind right now. Convert Rainbow Dash.
