Chapter Two

The portal flashed a lurid purple as a small squad teleported onto an empty suburban street. It wouldn't be long before the crystal hearts detected their presence, so they would have to set up their ambush quickly.

Yellow scanned the street through her strands of blonde hair, sensing the presence of the latex soldiers around her. She pointed at a tall brick wall fencing off a house from the street. “You two, unlock that gate and hide around the rear until the crystal hearts appear. Jump in with a surprise attack when it looks like the main force is losing.”

She pointed at the others without looking. “Remain with the mushroom soldier. When they teleport in, approach me in a threatening manner. I will react appropriately.”

The soldiers pressed their hands together and nodded, the ball gags in their mouths flashing in acknowledgement. A hiss of steam blew out of the mushroom soldier’s top, but it said nothing. If it disagreed with her orders, it didn't say.

She didn't care. The shadow queen had placed her in charge of this mission, and it was her duty to carry it out. If she failed, however, that thing would make for an excellent patsy. It would be easy enough to assign blame if the monster were somehow to meet with an unfortunate accident.

The telltale sign of blue light flashes appeared at the end of the street. It was almost showtime - she just needed to hide the fact that she was playing for the other team.

She wrapped her gloved hands over the gem mounted on her breastbone. “Heart Power Make Up!” she shouted in a breathy voice, pleasure shooting down her limbs with each word.

It felt so good to concentrate the shadow energy within her, a pulsing need glowing within her crotch as she obeyed the shadow queen's demands.

Her body flashed, the purple coloration vanishing as her uniform changed back to the tight, yellow latex she had been wearing only a few hours ago. Her bangs pulled back, curling to either side to mimic her former hairstyle.

She didn't mind this too much, but the physical changes she had to undergo were simply annoying. She was proud of her corrupted body, and not being able to show off her busty breasts and ample hips to Red really sucked.

She didn't want to scare them away before she had an opportunity to infiltrate and subvert their operations, however. Her Mistress might punish her if she was that stupid.

Taking a few steps towards the glowing field, she recomposed her face as she spotted Red's uniform.

“Help!” she cried out, dragging her ankle on the ground. “They're on top of me!”

Her eyes widened as she spotted the suit Red was wearing. A fully armored dragoon suit? They must finally be taking this threat seriously!

Damn. If they hadn't been so prepared, she might have considered grabbing Red right here and now.

Blue had shown up too, though, and she didn't think she could get both of them at once. It was best to stick to the original plan.

Dragging herself towards them, she winced in pain and slowed her gait. This gave the latex soldiers more time to close the gap, lending verisimilitude to the danger she was in.

“Don't worry, Yellow, I'll save you!” shouted Red. “Dragoon Shove!’

Jets blasted from her ankles, her suit accelerating towards Yellow at a rapid pace. Yellow made a small cry and tumbled to the ground, spinning herself neatly out of Red's line of fire. What was she thinking? That was damn dangerous!

The concussion of the force wave blew past her, knocking the latex soldiers off their feet. It was too bad for them, but their plan A was already busted. It was time to go with the more subtle approach.

Crawling along the ground, she clenched her teeth together as she spotted the latex soldier reinforcements arriving from behind the brick wall. A toxic cloud of gas expanded from their feet where the mushroom soldier had fired a volley of its mushrooms. This would prevent Red from getting too close before they could lay their hands on her.

The idea had been good, but they had underestimated the abilities of Red’s new suit. She spotted them right away, slamming her foot into the ground. A whirling wind expanded outwards from the impact, blowing the green cloud away.

This left the soldiers exposed, and Red quickly dispatched them with a second shove that knocked them right back into the wall with a tremendous crash. Oh well, she had never really expected the brainless troops to capture Red - while wearing the dragoon suit, she was far too powerful for that.

Fortunately, the suit did have drawbacks. It was only able to sustain full capacity in short bursts, and as it linked to Red’s heart crystal, she would find herself experiencing momentary weakness right about now.

Narrowing her eyes, she spotted the mushroom soldier creeping in from the side. The monster had timed its attack perfectly, lifting its hands to generate an incapacitation globe. If that hit Red, the battle would be practically over.

Before the orb could leave its hands, however, Blue scooted in front of Red, the coolness of her expression matching her color. She placed her hands over the cerulean gem mounted to her chestpiece. “Crystal Heart Deletion,” she said in a disinterested voice, as if she was cutting the heads off of flowers.

A wave of energy blasted from between her fingers, spreading wide to encompass the mushroom soldier as a terrible crackling sound filled the street. The creature’s body wavered, then disappeared, leaving behind nothing but a smoking pile of dust. Scary!

Red laughed, moving in a wide circle as she circled back towards Yellow. “You got ‘em, Blue! Nice work. I’ll rescue Yellow and we can get out of here!”

“Okay,” murmured Blue, spreading her hands again.

Her body shone as the crystal heart energy encompassed her in a sphere. She rose off the ground and disappeared, leaving behind bright sparkling dots.

Red scooted to a halt, reaching out a hand to Yellow. She took it, her heart pounding as she stared at the other heroine. Her savior!

The gem mounted to the front of the suit glowed as Red shut her eyes. The latex soldiers had climbed back to their feet and were doggedly back on the attack, but they would be too late to stop her. “Heart Power Teleport!” she shouted, a glimmering energy field popping into existence.

Their surroundings faded out, replaced with the familiar view of the teleportation chamber. Yellow sighed as the tingling energy faded, leaning an elbow against the floor. “Thanks Red!” she said, imbuing her voice with fatigue. “If you hadn’t shown up when you had, I would have been done for!”

Red placed her hands against her hips and barked out a laugh. “I very much doubt that!” she declared. “You always find an answer, Yellow! You work harder than all of us!”

Her face shadowed as concern tugged at her lips. “I seriously thought that was going to be it, though! Where are those things coming from?”

Yellow schooled her expression, keeping a grin off her face. If only she knew!

Now wasn’t the time to reveal herself, however. The Onyx Queen had given her what she needed to corrupt her friend, but she needed to look for an opening. They were all tired right now, but Blue was still hanging around somewhere. She needed a good, uninterrupted stretch of time to get Red to accept the Shadow Queen as her new Mistress.

Speak of the devil and she appears. She couldn’t keep the frown off her face as Blue stepped into the chamber, her eyes fixed on Yellow.

“Why didn’t you follow us?” she asked sharply. “We wouldn’t have had to come out to rescue you if you had stuck to the plan.”

Red raised her arms to placate Blue. “Come, now, we’re all back in one piece. Why are you nagging her?”

“No, it’s okay,” sighed Yellow, sagging to the floor to make herself as small as possible. “I tried to teleport back here, but I was in a panic. I couldn't visualize the room well enough to make the connection, so I triggered it without a destination in mind.”

“That's damn dangerous!” exclaimed Blue, cursing under her breath. “You could have ended up practically anywhere!”

Yellow nodded. “I was out of options. Would you truly say you wouldn't have done the same thing in my place?”

“No, I wouldn’t have. Because I know this place like the back of my hand. When are you going to start taking this seriously? You could have been taken!”

Excellent. She had accepted Yellow’s explanation, shifting over to mask her fear with anger. She settled down, knowing that there was no way Blue would see through her disguise.

It would be so delicious to corrupt that one, peeling away her cool layers to reveal the boiling emotions underneath. As her self identity fell apart, she’d pluck at her psyche, presenting the disparate pieces to her Queen.

After she had been put back together again, she’d be a devoted servant of the Queen, just like her. She couldn’t wait to see it. Couldn’t wait to do it.

She opened her mouth in a wide yawn. “Isn’t it getting late?” she asked. “I want to get cleaned up and turn it. That near miss was pretty terrifying, but I still have some assignments to get done for next week.”

Red chuckled. “Always the dutiful one, even when you get injured. Just… take it easy, huh? And let me know if it’s still causing you pain in the morning, we can go get it looked at.”

Yellow shook her head. “I think it’s just bruised,” she said, getting to her feet as she gestured at her ankle. “Looks like I can stand on it well enough. It’s already starting to feel better.”

She had never actually been injured, but they didn’t need to know that. Leaning over, she pressed at her skin. “Ow,” she exclaimed, shaking her head. “I probably shouldn't do that.”

Blue rolled her eyes. “She's fine,” she announced. “Let's go get ready for bed and regroup in the morning. We'll do a retrospective then on what went wrong.”

“Yes, captain,” murmured Yellow, her face twisting into a smirk as Blue's face flushed.

She might have a cold personality, but that was just a defensive mechanism to hide her thin skin. Of the three, she was going to be the easiest to corrupt, because Yellow knew all her buttons.

“Right,” Blue snapped out, crossing her arms. “Do as you want.”

Red grabbed her shoulder before she could flounce off in a huff. “It's a good idea,” she said soothingly. “We can ask Guest if it has any information about these new enemies. We've only encountered the latex soldiers before, which makes this concerning. Whoever is coordinating these attacks must be ramping up for something large.”

Blue nodded gruffly, shaking off Red's grip. “I'll ask the AI,” she said, holding her arms stiff by her sides. “I should have more information tomorrow.”

“Good,” nodded Red. “We’ve all had a big fright today and we're emotional about the near miss. Relax, we're safe here. This war isn't over just yet!”

If only she knew!

She could feel the dark mantle of the shadow queen pulsing inside her, waiting to be unleashed. It was getting tiring keeping this form, and she needed some alone time to relieve the pressure.

“I'm taking a shower,” she announced.

She took a step towards the door, pretending to wince as she put weight on her leg. She could feel Blue's stare on her back, and she smiled internally.

Sowing dissension in the ranks was only the first step. If Blue decided to go sulk by herself tonight, that would play right into her hands. Perfect!

Rounding the corner, she increased her speed. The darkness inside her was becoming more insistent. She needed to get to a safe environment so that it could be let out without any cameras spotting her transformation.

Fortunately, it wasn't a long trip to their living quarters. The alien intelligence that had designed this space station had at least been logical, if not particularly knowledgeable about humans.

The various accommodation blocks were focused around a central core, color coded so that it was easy to navigate. She turned down the red corridor, holding herself back from sprinting as she passed through a shared living space.

In better times, they would have eaten a meal together and watched a film or two, laughing at the antics of the onscreen villains. With their relations strained, they were instead choosing to spend time on solo activities. Excellent!

The threat they faced was more serious than the others knew, and with any luck, they wouldn't figure it out before it was too late.

Striding to her door, she waited for the alien AI to register her presence and key it open. Scooting past the bed, she made a beeline to the bathroom, breathing hard as the door snapped shut behind her. Finally!

Her body felt too small to contain the powers within, but now she didn't need to. She bit her lip as dark pleasure exploded from her core, the logo on her belt changing to the stylized A of the shadow queen.

Mistress! Groaning, she let the feeling of utter loyalty wash through her as tendrils expanded from the belt, caressing her pussy.

Getting into the shower, she squatted against the wall and groaned as the latex suit expanded upwards, the ends of the tendrils forming cups that folded over her breasts.

Wrapping her hands over her tightening orbs, she caressed herself as her nipples stood upright. She groaned as her flesh spilled out of her hands, breasts rising as they were held in place by the rigid suit.

It felt so good to let the corruption free! She just had to watch!

Stumbling out of the shower, she positioned herself in front of the mirror, shuddering as she braced her knees against the cabinet. She licked her lips as they began to turn violet, grabbing at her melon-sized breasts as her eyes glowed. Yes!

Squeezing her thighs together, she shivered as lines appeared on her pale face. Her hair shifted, the bangs growing longer to complete the look.

Mouth agape, she let out a long moan as a faded vision of her Queen appeared in the mirror. “Hail to the Onyx Queen!”

Her legs wobbled as her Mistress tilted her head up, blazing violet eyes sparkling through the veil.

A flash of light blinded her as the latex tendrils crammed into her pussy, writhing as they pried open her inner lips. She cooed as they plundered her tunnel, squeezing her rock hard nipples as she surrendered to the corruption.

She was Her servant. She was Her slave. Her glorious empire would be ascendant, an army of Dark Crystal Hearts reigning over this world. Latex covered soldiers would enforce Her will, drowning the world in the ecstacy of obedience. If this was what it felt like to lose yourself in Her glory, how could anyone possibly resist?

Her body tensed and she cried out, making breathy little hisses as she praised her Queen. Her lips formed into a wide smile as a corrupted uniform with an armored harness appeared in her mind. Yes, this was exactly what she needed to bring Red into the fold.

Her body jerked as she was showered with pleasure, enjoying the thick plug that the latex suit had formed in her pussy. Thrust, thrust, gush!

Black corruption burst forth from her vagina, dripping onto the floor. More spurted from her nipples at high pressure, droplets splattering over the mirror.

The vision of her queen faded, and she sighed, taking in the mess, evidence of her corruption. Reaching down to her thighs, she rubbed her finger through the fluid, bringing a dollop up to her violet lips.

Her eyes glowed at the sweet taste. Pure corruption. She wouldn't mind feeding some of this to Red.

She had work to do before that could be done, however. Staring at the messy fluid, she grinned as it began to roll together into a black, shiny sphere.

Not that kind of work. She wasn't a maid. This mess would solve itself.

The blob rolled up the wall, speckles of corruption jumping from the mirror to the main body as it neared the vent. Diffusing through the grate, it vanished, leaving a sparkling floor and countertop behind.

She momentarily worried about when it would reveal itself, but that was none of her business. Once her goal was achieved, the danger of her exposure would go down. There was no way the blob would find a new host before then, surely.

Perhaps this was a reminder from her Queen that she shouldn’t dally. Her move on Red had to happen tonight, and she had just the thing to ease her into her new role as the Shadow Queen’s pet.

She imagined the loops of her Queen’s armor plating clasped around her captain’s body and grinned. She was so eager to find out what Red would look like after she was corrupted! That treat would be better than any of the chocolates she had hidden all over the base.

Stepping into the shower, she turned it on, turning around to enjoy the heat. This was supposed to be relaxing, but she was on edge, plotting out the best way to trap Red.

Resting her hands over the top of her bobbing breasts, she gave them a shove, enjoying how they tingled under the latex coating. The suit had bonded with her skin again, giving her enlarged nipples a slick sheen. With any luck, she would be feeding those to Red soon enough.

Her small mouth would suckle on the corruption, her body writhing as the latex suit gripped her body. Her downfall would be marvelous.

She let go of her breasts, bracing her hands on her hips as she turned around. Droplets of water scattered off her glossy skin, giving her thighs a reflective sheen. By all accounts, her new body was grossly lewd, attractive and horrifying in equal measures. She loved it.

She hoped that her Queen would change her further once she had captured the other two members of her team. Her body already belonged to Her, but to be repurposed as Her weapon would be the icing on the cake!

She shook, hissing as her hands crept towards her pussy. No. This was no time to lose track of herself. The queen came first.

Sighing, Yellow stopped. The voice inside her brain was right. Unfortunately, she needed to keep herself in check. Fortunately, she only needed to do this for a few more hours, after which sparks would fly!

Grinning to herself, she placed her hands over the tops of her breasts and pushed. “Heart Power… Make Up!” she hissed, feeling the corrupted core within her stir to life.

Her latex suit creaked in protest, but the surface began to ripple, moving at her command. Her mouth formed into an O as it pulled its tendrils out of her vagina, licking over her mons as it withdrew upwards, into the belt.

Her breasts shrank, the evidence of her corruption swooping around and up, vanishing into the pulsing gem on her breastbone. The twin points of darkness pulsed, heat expanding to grip her body.

She moaned in pain as a flash of negative light filled the shower, sealing away her new form. For a time.

Turning off the shower, she turned and clasped her hands over the transformation gem. “Dark Crystal Heart Power… Heat!”

Her skin began to sizzle, water evaporating instantly to steam. This might be a frivolous use of her powers, but using some of her excess energy would help to keep her dark core in check. This was only a stopgap measure, however - as time went on, her power would continue to grow, until she would inevitably be forced to reveal her true form.

She had limited time, so she had best use it wisely. Exiting the shower, she gave herself a knowing smirk in the mirror as she padded out into the bedroom. She needed something demure and unassuming, in case the others came looking for her.

Opening the chest of drawers, she chose the first set of underwear and pajamas she found. Clothing used to be a great source of pride for her old self, but as a Dark Crystal Heart, the only thing she wanted to do now was to wear her Queen’s uniform.

Pulling on the soft outfit, she put on some socks and jammed her feet into a pair of slippers, staring into the mirror. The loose clothing failed to show off her bust size, which was naturally small anyway.

What a shame, really. If you couldn’t flaunt what you had, what was the point?

Shrugging, she sat down at her desk and clicked on the light, flipping open her laptop. Grabbing a notebook, she turned to a page she had already used, shuffling a couple of assignment papers around. This would at least make it look like she was working, though she didn’t have any plans to actually complete any assignments tonight.

Schooling wasn’t in her future. Only servitude.

To that end, she needed to prepare the groundwork. Logging onto the laptop, she opened up the hub application, pinging the AI. A pulsing, blue globe appeared on top of her desk. “How may I help you, Kiro?” it asked in its eerie, human-like voice.

“Guest. It’s good to see you.” She sighed, glad that it hadn’t detected anything odd about her. “Who else is still up and about?” she asked, starting with an innocent question.

“Red and Blue are sharing tea in the Red kitchen block. All others have turned in or have left the station on other assignments,” the AI replied in a measured tone.

“Set a reminder for when Red decides to go to bed,” requested Yellow. “I have something I want to discuss with her.”

The orb spun. “As you wish,” it said. “Reminder set.”

She folded her hands and leaned forward, giving the AI a cagey expression. “We haven’t really talked much about you, have we? What is the origin of the crystal heart powers?”

The curved rectangles composing the sphere halted, as if it was considering how to answer her question. “The universe needs heroes,” it said in a different voice with a peculiar accent. “The crystal heart power devices were developed to fight against incursions from negative space. Without them, we would be powerless to resist their predation on the good citizens of our reality.”

“Who is the driving force behind negative space, and why must they be stopped?” she asked, her voice imbued with a hint of curiosity.

She didn’t care that much, as she served her Queen implicitly. It would be nice to know Her motives, but they wouldn’t materially change her servitude.

“Negative space is the abode of creatures that are the antithesis of life,” continued the unusual voice in a scholarly cadence. “We must always resist their infiltration of our dimension, otherwise their hunger will infest our desires. We would become their slaves, unable to think of anything other than pleasing them.”

“What’s the problem with that?” she asked. “You say that they are the antithesis of life. What does that really mean? If they ‘eat’ us, will we die?”

“No,” replied the voice, sounding annoyed. “But you will become a hollowed out shell, an extension of their will. Whatever you want to accomplish in this life won’t matter any more. You’ll only have one purpose: to serve. A brainless automaton for the negative space, a pure avatar of evil.”

Of pleasure. This thing wasn’t telling her the whole truth. How could it? It was a simple machine. It had no idea the kind of ecstasy her Mistress could provide.

“I get it,” she sighed, placing her hands on the desk. “But how are we going to stop them? With every attack, they steal more citizens and turn them into those latex things. At some point, they’re going to have the critical mass needed to overwhelm us, whether we like it or not.”

“That is a true challenge,” acknowledged the AI, swapping its voice back to its more neutral accent. “We’ve been on the defensive. Our only chance for success is to band together and make a counterattack. I am collating possible plans.”

“Good. Let us know when you have something we can use. In the meantime, please show me the layout of this place. I want to get a better idea of where everything is in case they decide to attack us here.”

The AI beeped, and her laptop’s screen refreshed, showing a map of the station. Blue lines delineated rooms, with terse text explaining each location. Excellent. This was exactly what she was going to need to help her Mistress take control!

Expanding the map, she located her room and traced a path to Red’s, confirming her route. This accomplished, she pulled back and looked at the whole picture, looking for the best ways to assault each section.

There were several areas that weren’t marked, which might contain secret devices. Perhaps one of them housed the AI core? They were definitely worth investigating, so she made a mental note to mention them to her Queen.

The voice of the AI broke in. “Excuse me, Mistress, but I am alerting you as you requested. Red has finished with Blue. Would you like me to notify her that you wish to speak with her?”

“No,” said Yellow smoothly. “I’ll go find her. Thank you for your assistance, you may retire.”

The AI beeped, the globe fading out. She snapped the laptop shut, pressing her hands over her heart. It was thudding like a drum set, excitement tingling in her limbs. It was almost time. She knew what she had to do!

Straightening her back, she marched towards the door, which opened silently. She knew that the AI did not monitor the interior of personal quarters unless asked, which was perfect for her needs. Red wouldn’t know what hit her.

Taking a right, she marched down the corridor, glancing at the side of the space station through the floor length windows. The blackness of space was visible near the bottom, stars twinkling at her. She gave them a grin, knowing that there was so much more out there beyond their tiny little planet. Plenty of worlds for her Queen to conquer!

Her breasts throbbed as she passed the next door, noting the red privacy light. Blue must be safely ensconced inside. Good, she didn’t need any interruptions for this.

She increased her pace, her body beginning to tremble. She had less time than she had thought before her disguise wore off. Just a few more minutes!

She slowed down in front of Red’s door, pausing to tap at the screen mounted to the wall. A soft chime rang inside the quarters, and she waited calmly, palms sweaty.

The screen popped on. “What is it?” asked Red, her hair tousled.

She had probably just gotten into bed. “Sorry to interrupt you,” Yellow said softly. “I had something I wanted to discuss.”

“Can’t it wait until morning?” groaned Red.

“I'm afraid not,” replied Yellow. “I saw something during the battle that's important, and I want to discuss it with you first.”

Red groaned, and the screen turned off. She was probably thinking that Yellow was trying to keep something from Blue, and that was true in a manner of speaking.

The door hissed open, and she stepped inside, examining the decor. The base set of rooms supplied to them on the station had come furnished, but they had been uninspired, as if copied from a magazine.

It had been up to each of them to personalize them in their own style. Yellow had hung pictures from her younger sisters on the wall, along with reminders of family events. Anything to make the place feel more homey.

Red had taken a different tack, replacing all of the linens and carpets to match her color scheme. The end result was a rather garish display, but none of them had the heart to tell their captain that she lacked a sense of style.

She hadn't replaced the floor length mirror positioned off to the right side of the bed, however, which was going to make her job much easier. How could they ever have guessed that something so pedestrian would contribute to their downfall?

Yellow marched up to the bookcase, admiring the stuffed bears Red had jammed between two sets of books. “I remember buying this one for you,” she said, petting the soft fur.

“What's this all about?” asked Red sharply. “I'm not in the mood to reminisce. I'm tired, and I want to turn in.”

Yellow spun around, taking in her captain. The other woman was dressed in floral print pajamas, her hair coiled up into a ponytail. She was cute, but soon she would be erotic.

She paused as she noticed a faint glint of polished blackness hiding under the bed between Red's knees.

She understood. Her Queen knew that this was her goal, and she had set the table for her. It was amusing how simple her captain's corruption would end up being.

“What did you think of the uniform the elite soldier was wearing during the battle?” she asked. “Did you notice anything odd about it?’

Red's brow creased. “It was different from the usual rubber soldiers. It had some kind of mushroom shaped head and abilities to match. I don't see what you're getting at.”

Yellow took a step forward, feeling the heat of her corruption coalescing around her. The light of the room darkened subtly, but Red didn't seem to notice.

“You're looking at the big picture, but I'm thinking of something more specific. What about its armor?”

Red folded her hands, looking uncomfortable as Yellow loomed over her. “It was a gray harness, with a purple gem mounted in the center. Look, what is this all about?”

Yellow turned and sat on the bed, reaching her arm around Red's back and grabbing her shoulder in a hug. “You're not quite seeing it yet. Here, look in the mirror and I'll show you what I mean.”

Confused, Red turned towards the mirror and gasped. “What is that?” she groaned.

It was Red, dressed in her pajamas on the bed, but the harness the mushroom soldier had been wearing had appeared around her shoulders, resting against her chest. The blazing violet gem of the Shadow Queen blazed on the front, the pupil of Her eye staring back at the heroine.

A thin line of gray armor ran down between her breasts, expanding into a belt that cupped her hips. Underneath, a strip ran under her crotch, clenching against her privates. It was seamless, with no obvious way to take it off.

“It’s the enemy!” shouted Red, reaching up to grab for her crystal heart.

Fishing out a ruby red gem, she placed her hands around it, closing her eyes. “Crystal Heart Make Up!” she shouted, invoking her magical powers.

Her body heated up, but Yellow clung to her tightly. She knew that if she lost this opportunity, there might not be another. Besides, Red was already losing herself, she just didn’t know it.

She blinked as a flash of light assaulted the room, Red’s body rippling as her crystal heart uniform appeared. She raised her hand, a bracelet about her wrist. “Crystal Heart… ooh!” she groaned, discovering that the harness displayed on the mirror had suddenly appeared on top of her sleek uniform.

The strip running under her privates had thinned, her voluptuous ass filling out the harness. The two side pieces stretched down and over her transformed butt, clinging tightly to her body.

Red touched her buxom hips, crying out in dismay. “What’s happening to me?” she squeaked out.

Yellow chuckled, her hand clutching at the heavy, gray armor which wrapped over her captain’s shoulder. “You’re being turned into a dark crystal heart soldier. Doesn’t it feel glorious?”

“What are you talking about?” groaned Red, trying to shake off her grip.

“It’s quite logical, really,” explained Yellow. “Blue destroyed her soldier, so the Queen needs a replacement. Tell me, how does it feel to have your body turned into a lewd work of art?”

Red clenched her hands, breathing hard as she tried to get past the erotic heat that was suffusing her body. The harness was writhing, twin tendrils wrapping around her upper torso and under her breasts, lifting them up as they expanded in size.

Her captain jumped to her feet with unexpected strength, causing Yellow to groan as she was tossed to the floor. “Crystal Heart Shine!” she shouted. “Crystal Heart Fire!”

Nothing happened, and Yellow laughed. “It’s no use,” she croaked out. “Your powers have already been subsumed by darkness. You cannot call on your Crystal Heart powers once you’ve become a Dark Heart!”

“A what?” groaned Red, a look of utter dismay on her face as her fingers curled.

Yellow could tell that Red was losing the battle. Another small push, and she’d succumb to the pleasure.

“What are you worried about?” asked Yellow, climbing to her feet. “You already know what you must do. It’s only natural.”

She pressed her hands over her breasts, massaging them through her pajamas. “There’s no reason to resist. Give in and feel yourself up. Being a Dark Heart is all about pleasure.”

“What has happened to you, Yellow?” asked Red, her face pale. “I thought you were better than this!”

“Better than what? You?” Yellow asked, her face twisting into an erotic grin as she played with her breasts, which were expanding in size as she released her hold on the corruption. “My Queen has given me everything I need to ensure my victory, and you are only moments away from finishing your transformation. You can’t resist it. Tell me, how does it feel to have the Shadow Queen’s power flowing through your veins?”

Yellow’s breasts were plumping up nicely, and she could feel her hips widening, too. Reaching down, she shoved a hand under her panties, sticking a finger into her pussy as she groped herself. Seeing Red fall was the most erotic thing she had ever seen!

She twisted her face into a scowl. “You were always better than us, Red. We could never catch up to you, no matter how much we tried.”

“It’s not a competition,” complained Red, trembling as the lower part of the harness squeezed against her privates. A wet spot was forming around her pussy, her body responding to the carnal corruption.

“Not anymore,” breathed Yellow. “We'll all be equal in Her sight. She will make it so. All you have to do is give in, like I have.”

She relaxed the rest of her restraints, letting her corrupted self come to the fore. Her body flashed and the pajamas disappeared, replaced by the latex uniform bestowed upon her by the Queen.

She gasped, letting out a coo as her fat nipples protruded, rubber tendrils pushing inside. Black fluid trickled from the tips, and she lifted a breast up, giving it a lick with her extremely long tongue.

Red appeared stunned, her breath hissing as she took in the extent of her former teammate's corruption. “No!” she said, sounding defeated. “It can't be! The Crystal Hearts can't lose. We're the arbiters of peace!”

“Can. Can't. It's such a limiting world view,” growled Yellow, her voice husky. “I find it far easier to acknowledge reality. Our Onyx Queen is coming, and we shall prepare the way for Her ascendance!”

Red grunted, her face scrunching up as her nipples were squeezed by her uniform, the flesh underneath being remodeled by the corruption. Soon, she wouldn't look any different from Yellow. Wouldn't be any different.

Red stopped tugging at the harness, true fear in her gaze as she spotted the purple talons growing from the tips of her fingers. “I have to stop this!” she shouted, spinning around.

Yellow felt a faint pulse of alarm in her chest. She should have expected this. Red had always been the best of them, but Yellow really had thought that she'd be just as helpless when faced with her Queen's corruption. She was a fool!

Before she could leap into action, a ball of shiny rubber jumped from under the bed, stretching out to wrap around Red’s ankles like a bola. The unexpected attack took her by surprise, and she tumbled to the floor, rolling over into the chest of drawers with a sickening smash.

Yellow rushed over to her, grabbing her shoulder. “Are you okay?” she asked, genuine concern punching her gut.

Red began to laugh, clutching her belly. At first, Yellow thought that this was a burst of hysteria, but when she turned the captain over, she spotted a bright, violet light glowing in her pupils.

Wheezing, Red mewled, running her hands up to her chest in an animalistic fashion. “Let's get you onto the bed,” declared Yellow, worried that she had suffered a head injury.

Grabbing Red's shoulder, she lifted her to her feet, running an arm around her back for stability. The latex orb that had captured her rippled, turning back into a sphere as it rolled over to the mirror.

Yellow shrugged, more worried about her former captain. Fortunately, the strength boiling through her arms was more than sufficient to bring her over to the foot of the bed.

Turning her around, she dropped her onto the comforter. The collar at the top of Red’s suit had expanded, turning into a ring of metal around the bottom of her throat. The purple gem at the base stared out at her, throbbing with the Queen's power. She shuddered under the gaze, knowing that each of her actions was being judged.

“How do you feel?” she asked, frowning.

It didn’t look like she had other injuries, but she seemed dazed.

“I feel… amazing!” Red burped, frowning as she looked down.

“Why are those so big?” she wondered, wrapping her talons around the lower curve of her huge breasts.

She pressed them upwards until the enormous masses squished against the upper arches of the armored harness. Giggling, she pricked one of her nipples with a claw. “Squishy,” she murmured.

She lifted her head, giving Yellow a wicked grin. “You've been holding out on me,” she said. “You didn't say how tight this would feel.”

Yellow shrugged, returning her grin. “I can't describe every little detail. Some things you just have to experience for yourself.”

Red purred, straightening her back to give her chest a little pop. The suit tightened around her breasts, keeping them even and level. She chuckled. “I barely feel the weight at all!”

Lifting her arms, she examined her talons, twisting them back and forth as she opened and closed her hands. The tips of her fingers were a darker purple, contrasting with the lighter purple of the fingerless latex gloves running up both her arms.

“Delicious,” she proclaimed, licking her lips with a pointed tongue.

She stared at Yellow with hunger, and she couldn't resist. Leaning in, she gave her former captain a full kiss on the lips, lingering as Red placed a hand behind her head, urging her on.

Their tongues tangled together as they played, enjoying the taste. A wet pop sounded as Yellow pulled back. “Welcome to the Dark Hearts,” she purred.

The dark core in her heart pulsed. “I can't wait to share more with you,” she proclaimed. “First, though, I must finish with what my Queen has provided.”

She took a step back, lifting her hands and pressing them together. The outline of a shape appeared, summoned from negative space. Red gasped as her eyes took in the rounded top of the hard helmet. “That’s… for me?”

Yellow nodded. “You must take the place of the soldier Blue vanquished, and become one of Her lieutenants. You will join me by Her side, and the two of us will help each other to turn Blue. That is Her command.”

Taking the helmet from Yellow, Red studied the curved mushroom shape, raking her talons over the hard, red surface. It was split over the top by a wide, white stripe. Below that, there was a ruffled, white cloth piece attached, which would cover the bottom of her face, flanked on either side by yellow frills.

Red turned it around, eyes blazing with desire as she grabbed a section of the gray fabric dangling from the bottom. Without ceremony, she pulled it on over her head, working at it until the white cloth was situated over her face, the mushroom helmet propped on her head.

Smoothing the gray fabric at her neck, she turned to Yellow, clawed hands waiting calmly at her sides. The gem on her harness pulsed, the slitted pupil watching Yellow with satisfaction. A belt was now cinched around her waist over the harness, a stylized A in the center proclaiming her body as property of the Onyx Queen.

The fabric on the helmet suddenly rippled as it compressed over Red’s face, a breathy hiss coming from her lips. Within a matter of moments, it was rigid, looking like teeth, the yellow frills becoming flesh. Red groaned like an animal, yellow blobs on the helmet growing into mushroom caps. She had truly become Her monster.

There was one final touch to complete her descent into servitude. Lifting her hands a second time, she concentrated, materializing Her collar.

Raising it up, she secured it around Red’s throat. Red growled as it immediately began to glow Her color, the deep purple band becoming smaller as it locked itself in place. There, now she was complete!

Duties finished, Yellow admired her work. “You’re a perfect erotic specimen,” she sighed, stroking her shoulder. “I wouldn’t mind spending some time with you, but I’m certain our Queen will have new orders for us.”

An odd noise drew her attention. She turned towards the mirror, noting the rippling blob of rubber that was sitting nearby. She was being summoned.

Stepping up to the mirror, she crossed her arms under her enormous breasts, squeezing the flesh together. She was looking forward to playing with them more, but her Queen took priority.

Widening her stance, she stared into the mirror blankly, taking in the mushroom creature that sidled up next to her. Unlike the Queen’s former lieutenant, Red was soft and full of curves, with an incredibly lascivious body. She would very much like to sample those breasts - if the former heroine was amenable, of course.

The light in the room dimmed further, a hissing shadow forming in the darkness. Heavy weights dropped onto her shoulders, and she blinked, her heart throbbing as she noticed the heavy breasts squeezing around her head. Her arm immediately shot up.

“Hail to the Shadow Queen!” she hissed. “Glory to Negative Space! I serve!”

Red's hand shot up, too, but all that came out of her mouth was a muffled growl. She had become nothing more than a beast, to be used at her Mistress’ pleasure.

The looming head of the Queen appeared, her purple eyes glowing through the veil. Yellow detected that she was satisfied, and there was also a sense of… curiosity?

“Well done,” she whispered into Yellow’s ears, and she shivered in pleasure as her corrupted core responded.

“I wasn’t expecting you to capture her so quickly, or so thoroughly. I am pleased.” Her hands closed over Yellow’s breasts, giving them a slow squeeze.

She groaned as her body responded, her core throbbing as it resonated with the presence of her Queen. Her eyes rolled as something long tickled at her ear, curling over to stick itself inside. Her Queen was licking her!

Her thoughts fled, being sucked out of her head as her Queen manipulated her body, thighs trembling as she juiced. What a magnificent reward!

The tongue rolled around in a lazy circle, inserting further, until she felt as though it was caressing her mind. She made soft cooing noises as the pleasure centers of her brain were touched, tugged.

When the orgasm came, she was barely thinking anything at all, eyes blank as the glory of her Mistress drowned her mind like a flood. A raw hunger imbued her remaining thoughts, demanding more, needing more.

It was almost frightening, and she could sense that she was quickly losing her sense of self. While her body trembled with pleasure, fear tingled through her limbs, with the knowledge that her Queen could take everything from her with a snap of Her fingers.

Suddenly, her Mistress retreated, and the fear vanished, replaced with ecstasy. She vibrated, writhing as the Shadow Queen tweaked at her nipples.

Spurts of black fluid erupted, drenching the rubber ball which had rolled in front of her. The splatters were subsumed into its mass, the ball increasing in size as she gushed out her pleasure all over it.

Her Queen hummed in her ear. “That was only a taste of My majesty. Recruit another, and perhaps you shall have the opportunity to experience it again.”

Yellow sighed, feeling the faint itch of her Mistress’ hunger tickling her brain. It wasn't needy enough to be distracting, but it had become ever present. Internally, she praised her Queen for blessing her with a piece of Her soul.

The Queen's hand drifted over her shoulders as she moved to Red, resting a dark hand against her back. “I've been waiting for you to submit for some time,” she hissed, her breathy voice curling around them in a velvety caress.

“This was unexpected, however. You fell harder and faster than I was anticipating.” She gripped Red's neck with her claws, and the former heroine growled, her transformed face vibrating. “Still feisty. I like it. You may be a suitable candidate.”

She swirled her fingers, pointing at the rubber blob rippling next to the mirror. The blob began to morph, stretching upwards into a thin body. As the mass at the bottom pulsed, it filled out, taking on the attributes of a feminine form.

A head grew outwards from the neck, its face a blank, rubber dome with no features. A gaping hole opened up, but it made no noise, stepping forward on amorphous feet.

Red growled at it as it stopped in front of her. The gooey mass reached up a slimy arm to touch the purple gem sparkling on her harness above her chest.

Squealing with delight, the golem grabbed either side of the upper harness with both pseudo hands, its body becoming liquid as it jumped off the floor. Red grunted as the rubber thing wrapped its arms and legs over her, the creature melting into a dripping mass.

Coiling over the harness, its body disintegrated, returning to goo as it oozed over the provided framework. Within a matter of moments, the harness was coated with its dark body, the creature vanishing entirely.

“It likes you,” sighed the Queen. “Very good. The two of you shall come to Me. I have more gifts to give.”

She clapped her hands together, her misty body vanishing into the shadows. The boiling darkness closed in on them, pushing them towards the mirror.

The surface shimmered, the image of the room behind them fading as the portal opened. Yellow stepped forward confidently, recognizing the telltale swirling purple of negative space. It was time to meet their Queen.
