Chrysalis has failed, and as such has abandoned her role as queen. Now with Equestria ousting changelings by the hundreds its adapt or die. Which leads the former queen with a desperate plan that involves a certain fashionesta.

Chrysalis is near death and must find a way to ensure her race's survival. Equestria has woken up to the threat they think the changeling's impose and so a desperate last gambit is enacted and a formerly nameless changeling must undergo an ancient ritual in order to bind herself to the element of generosity herself. From her they hope to birth a new queen, one capable of adapting and working with the ponies in this new world they find themselves in. One where they cannot hide and cooperation is the only way.

Kink warnings. Lots of worldbuilding. Changeling gooification, dark rituals, fusion, forced heat, large insertion, body modification, egg insertion, belly bulging, mind altering. And probably more.

Oh hey, top of popular stories. Didnt think this story would make it even that far.

A Desperate Gamble...

Harsh wheezing and the stumbling, off balance click-clack of chitinous hooves drew the nameless changeling’s gaze towards the entrance to his quarters. He cocked his head and quickly redonned his disguise, instantly replacing the black chitin with pale blue fur, her intimidating eyes replaced by a much softer blue, and finally her membranous mane replaced by a shoulder-length seafoam green mane that looked purposefully unkempt. The changeling straightened her posture and glared at the door.

“If that beggar has wandered into the barracks again I swear to Celestia I am going to give every one of you so much P.T. you’re going to throw up your small intestine!” She yelled, stomping over to the door and opening it, ready to chew out anypony who dared intrude upon the few short hours she had alone.

“Is that really any way to talk to your dear old mother?” Asked a frighteningly weak voice.

Moonlit Melody looked down and nearly lost her disguise at the sight of the huddled form before her. Clad in rags that seemed to be a mish-mash of at least three different cloaks and what looked like a chunk of a carpet was the huddled form of an undesguised changeling. Not just any changeling though, it was none other than her mother, queen Chrysalis. Moonlit knew this not only from the distinctive sight of the queen’s eyes but also the faint psychic echo that she felt within her mind, though it wasn't as strong as it had been; it almost felt like a worker’s, but that couldn't be...

Thinking quickly, she looked both ways and, noticing there were none of her ‘fellow’ guards around, she pulled the queen inside, locked the door and in one swift movement kneeled before her and discarding her disguise.

“My queen. Pardon my rudeness.” She begged, her voice returning to the strange buzzing sound that all changelings had.

The rag-clad changeling laughed, though it quickly devolved into a pained wheeze. “Worry not, my child. I know that you are merely keeping up your disguise, one that I must commend you on keeping throughout my failed invasion.”

The changeling winced at the sight of her queen and stood up, moving towards her bed. “Would you like some of my stored love? It’s mostly the love of a comrade, though it still tastes a lot like familial love.”

“Yes, please do.”

The changeling stopped. Please? Had she just heard that right? She shook her head and made her way over to her bed before getting down on her knees and reaching under it. Her hoof grabbed a metal container and she pulled it out. The box she held was small and heavily warded with a single clasp on the front. Pressing her hoof against it made it flash briefly in a bright green color before the ward dissipated and she flipped the latch to reveal a single bottle of teal liquid roughly the size of her hoof.

Delicately, she lifted the bottle from the case with her magic and levitated it over to her queen who accepted it with a nod. Tossing aside the cheap cork stopper, the queen threw the potion back, downing the majority of it in a single gulp. The changeling had to suppress a whimper as she saw the love she had worked several months to gather vanish in an instant. It was worth it though - it was for her queen, after all.

The queen stopped after the first gulp and replaced the stopper before giving the bottle back and licking her lips. Already she seemed more vibrant, her eyes losing a little of the milky opaqueness that plagued them and she stood a little taller.

Quickly replacing the bottle back into its case and reactivating the rune, the changeling placed the case back into its spot and resumed her kneeling position, drawing another wheezy laugh from the queen.

“Rise, there is no need for ceremony anymore, I am no longer your queen.” The former queen arched an eyebrow at the changeling’s still-kneeling but also not surprised form. “I taste no surprise in you, my child, and yet you kneel. Why?”

The changeling sighed. “Your psychic echo was not what it once was, combined with your… altered stature I knew what had happened, though I know not why you have come to me of all lings.”

The former queen stumbled over to a small pile of cushions, falling into their velvety embrace gracelessly. “Come, sit with me. We have much to discuss and not long to do so.”

The changeling obeyed, pulling a single cushion from the pile to sit on. “What has happened to you, mother?”

This time it was Chrysalis’ turn to sigh and she tossed back the hood of her rags, revealing a broken, scarred face nearly devoid of chitin and replaced by dense scar tissue. “Our expulsion from Canterlot has caused me a great deal of damage.” the changeling’s jaw tightened as she surveyed the extent of said damage evident across her former queen’s face. The tip of her horn was broken and leaked magical energy occasionally, taking the form of errant sparks of green. One eye was almost completely covered in a thin film, indicating deep damage that even a large intake of love could not handle. One fang was missing and, perhaps most glaring of all, was the lack of a crown upon her head.

“Damage that I cannot repair even if I had the desire to.” The queen frowned and she ran a hoof down her broken face. “In my desperation I underestimated a foe and lead my brood into a death trap. I am no longer your queen, but I have also chosen my successor.” She pulled back her ragged cloak and pulled out a solid green egg that positively hummed with energy. The changeling gasped and reeled back.

“Is that what I think it is? No mother, you couldn't. Please tell me my eyes deceive me!” The changeling cried.

Chrysalis sighed. “It is, I had to. The next leader of the changelings needs something I no longer have, empathy. You will take this egg and implant it within the element of generosity; her connection to the elements makes her a conduit for powerful magic. This magic is made even more potent by its association with generosity.”

“This is madness! Such a plan is doomed to fail! To think that you have underestimated the elements not once, but twice. What are you thinking?”

The former queen laughed bitterly. “This time I have not. I will remain here in Canterlot and surrender myself, requesting only that Twilight be present at the negotiation table. I will pretend to surrender myself and my changelings and beg forgiveness. I hope this will at least earn me enough good favor that they stop killing my children in the streets.”

The changeling grimaced, all too familiar with the frequent lynchings she was forced to break up. More painful still was when she had been forced to escort her brothers and sisters into the dungeons, never to be seen again.

“Ponyville is relatively quiet and I have set up a disturbance in the Everfree that will trigger in three days time that will distract the meager garrison left there. This should allow you to sneak into the home of the element bearer, implant the egg and…” The former queen hesitated, looking at the changeling with pity and guilt.

“And what, mother? What would you have me do?” The changeling pleaded.

“I… I want you to bind to her.” The changeling gasped. “Her body will not be suited to gestate a queen properly, as we grow to full size and have live births. Which is why I need you to alter her, guide her and keep her safe. Things you can only do if you bind to the element bearer.”

The changeling gritted her teeth and looked away from her mother, unable to meet her gaze. “Are you sure this is the only way?”

“It is… The next queen must grow to become not a predator, but a symbiote. The ponies know of us now and it will not be long until we are rooted out and destroyed forever. I cannot let that happen. I will do anything to ensure our race survives, even the unspeakable.” She hesitated, and the changeling looked over to where the queen drew forth one last object.

“No, you couldn't! I’m not worthy.” The changeling muttered dumly, staring down at the small dull crown that sat in the queen’s outstretched hooves.

“You will keep it safe until the new queen is born. Until then, you are the queen.” Chrysalis bowed her head and extended her hooves.

The changeling reached out, hesitating at the last moment only to snatch the diminutive crown from her mother’s hooves. “If that is your final order then I will obey. Though I disagree with almost every part of this plan, I will follow it through... for you, mother.”

Changelings could not cry, but at this moment Chrysalis wished she could. “Thank you, my daughter. You were the best infiltrator I have had in generations, and if anyone can carry this out, I know it’s you.”

The changeling nodded and reverently placed the crown upon the table between them. “Your will will be done.”

The Changeling sat deep in the booth of Sugarcube Corner, sipping on a milkshake of some kind. The actual type didn't matter to the changeling as she would have to regurgitate it later anyway. No, that part didn't matter to her. What mattered to her was the fact that whomever had made it had clearly been a master chef or at least loved their job. A pleasant warmth bloomed from the changeling’s fake stomach; it was the feeling of love being absorbed and she couldn't help but smile at that. She had heard of pony chefs who loved their job so much that love infused the food, or an object they used, but she had never felt it for herself.

She pulled again on the straw only to frown as little more than a tiny bit of the delicious liquid passed her lips. She looked down to see her milkshake was empty, drawing a smirk to her lips. She had never enjoyed a piece of pony food more than this, and the thought that her host would partake regularly in such a drink was a pleasant one. Perhaps it would make this whole ordeal slightly more enjoyable.

In a flash of pink, the waitress was before her, a huge smile on her face. “So, what did ya think?”

The disguised changeling smiled back. “It was wonderful. My compliments to the chef.”

The offensively pink pony giggled. “Thanks! I was trying out a new recipe and just loved, loved, loved how it came out! Can I get anything else for you?”

The changeling pondered it, tempted to ask for another, only to be interrupted by the sound of a distant explosion. “Another time.” She dropped a small pile of bits on the table and moved to grab her luggage next to the table.

“This is way too much, lady. I can't accept all this.”

“Then pay it forward, I’ll buy the next few orders that come through the door.” That made the pink pony smile and she nodded and zipped off.

“Thanks, mystery pony!”

The changeling smirked and grabbed the luggage case in her magic, delicately picking it off the ground and making her way out into the street. Once outside she frowned, noticing that a few ponies were running away from the general direction of the Everfree while the guards ran toward it. In the distance she could hear a magically amplified voice booming.

“Please stay in your homes. The Ponyville guard is more than capable of handling anything that may emerge from the forest. Do not leave your homes for any reason. Please stay-”

The changeling ignored the rest and made her way towards Carousel Boutique at a brisk trot, not wanting to stick out but also not wanting to risk dropping the case despite the fact that it was reinforced with every protection spell she knew.

Ponies of all shapes and sizes ran past her in either direction, not casting the unicorn a second look save for a stallion who stopped to eye up her flank for a moment.

Once at the door, the changeling hesitated, feeling the knife strapped to her hoof and hidden behind an invisibility spell. She cast a quick glance back and forth before knocking on the door, her entire body changing suddenly when she did. Gone was the confident expression, replaced by one of intense fear, her posture shifted low and she looked back and forth rapidly, as if expecting something to fly out and attack her at any second.

“Hello? Is anyone there? The guards are telling everyone to get inside but I’m not from around here. Can I stay inside until this dies down?” She called out.

Inside she could the faint sounds of hoofsteps on hardwood, coming towards the door. The steps stopped at the front of the door and the changeling could feel as though she was being watched. Clearly there was a peephole of some kind on the door, though she could not see one. The feeling quickly vanished though and the door opened to reveal a disheveled unicorn with pearl-white fur and light purple hair.

“Quickly darling, get inside.” The unicorn ushered the changeling inside.

The changeling nodded and gripped her case tightly in her hooves before trotting through the door quickly. Once through, the door shut firmly and a bar fell over it. The unicorn held her breath until the faint hum of enchantments kicked in, ensuring nothing would get in or out. The majestic unicorn breathed a sigh of relief and turned to her guest with a faint smile.

“Terribly sorry about the suspicion, but you never can be too careful these days.” She extended her hoof with a smile. “My name is Rarity, and welcome to the Carousel Boutique. I will skip with the sales pitch as I don't think you’re here to buy anything.”

The changeling reached out and tapped her hoof to Rarity’s. “Sorry, no. Maybe another time though?”

Rarity waved her hoof dismissively. “Don't think that you owe me anything, darling.” The distant sound of a roar could be heard through the boutique walls, causing both mares to jump. “Why don't we retire to someplace a little more comfortable, and one with a privacy enchantment?”

When Rarity turned, the changeling allowed a small smile to spread across her lips. Perfect. She thought.

Rarity trotted into the kitchen with the disguised changeling close behind. The room was relatively small, a simple breakfast nook sat in one corner, leaving just enough room for a fridge, a stove and minimal counter space. Evidently Rarity had prioritized the size of her boutique over gaining a few more creature comforts, which pleased the changeling greatly. The high ceilings and wide-open space of the storefront was uncomfortable for the changeling. Here, at least, she would be able to relax in a space a little closer to home.

The unicorn made her way over to the rapidly heating stove stove, placed the kettle on it and reached up to grab what looked like tea from a cupboard, only to turn and ask. “Would you like some tea, by chance?”

The changeling shook her head nervously and tapped her hooves together. “No, thank you. I wouldn't want to be a bother.”

“Nonsense, darling. How about some nice chamomile to calm our nerves, hmm?”

“Well, alright, but only a cup!”

Rarity giggled and brought down enough tea for several cups and set them aside. As she got to work making their tea, the changeling was beginning to formulate the beginning of her plan. But how was she going to distract her host? She had a few minutes to think and, in the meantime, she forced her poison gland to go into overdrive, producing a potent sleep agent in half the time that it would normally take. The draw on her love reserves was significant and her jaw ached, but it was necessary so she grinned and bore the pain with dignity.

Her host turned with two now full tea cups, presenting one to the changeling who took it with a shy smile. “Thanks.”

“It was my pleasure. Sorry about our quick introductions, but I didn't catch your name.”

“Moonlit Melody, at your service.”

Rarity sipped her tea and smiled. “Ahh, a musician. Not many of those in Ponyville, I’m afraid. What brings you to our fair town?”

Moonlit shuffled nervously, gripping the luggage in her hooves a little tighter. “My mother passed away not too long ago. I needed to get out of Canterlot and Ponyville seemed nice, if a little small.”

Rarity’s eyes lit up and she reached across the table, taking the changeling’s hooves in her own. “I am so sorry to hear that, darling. If you need anything at all, don't hesitate to ask.”

The changeling recoiled, startled by the generosity, despite knowing that it was her element. “I couldn't ask for anything I didn't earn. Maybe you could… No, that wouldn't be right.”

Rarity gripped her hooves tighter and smiled fiercely. “Whatever you need, darling. Maybe we could even work something out, have you play whatever instrument in my shop and I could pay you in bits or lodgings, if that would be easier.”

The changeling eyed her host’s cup, noticing it was still almost completely full. She had felt her poison gland full by then, she was ready. “I-don't know, let me… what is that?” Moonlit Melody peered behind Rarity, staring intently at the window behind the mare’s head.

“What? What is it?” Rarity spun around to look at whatever had drawn her guest’s attention, not noticing the changeling’s horn light up. She did notice the knock at the door though and she spun around again, even more confused. “What did you see?”

“I thought I saw somepony out there, but I guess my nervousness is getting the better of me.”

Rarity gulped and nodded, getting out of her chair and making her way to the door. “I suppose I should see who is there.” There was a hint of reluctance in her tone and the changeling could taste her fear, but despite this she pushed on and left the kitchen, intent on answering the door.

The changeling grinned and peeked out of the kitchen, noticing the mare was lingering, taking far longer to walk to the door than necessary. Perfect. She slipped around to the other side of the table, leaned over the unicorn’s cup of tea and discarding the part of her disguise that hid her fangs. Positioning one fang over the cup, she squeezed her poison gland and willed a thick drop of the potent poison into her brew. She switched to the other fang and did the same, listening intently all the while as Rarity looked through the peephole and hesitantly called out.

“Hello? Is anypony there?”

Predictably, there was no answer and the unicorn hesitated before undoing the locks and charms and opening the door and peeking out. “Hello! Is anypony there? This is not funny, Sweetie Belle!” After glancing around for a few seconds longer, she harrumphed and closed the door, securing it again.

Mumbling to herself, she made her way back to the kitchen to find her unicorn guest to be far more relaxed, sipping away at her tea. Rarity smiled despite the circumstances, Moonlit’s apprehension had been wearing on her and it was good to see she was calming down.

Rarity sat across from the unicorn once more. “Must have been the wind or somepony playing a joke.” She idly remarked.

Moonlit smiled. “Foals will be foals, emergency or not.”

“Too true, I’m afraid.” Rarity lifted the cup to her lips only to stop, her nose scrunching up as she caught the whiff of something off.

“Is something wrong?” Moonlit asked, a bit of apprehension returning to her voice.

Rarity silently chastised herself. You’re making her nervous again, Rarity. Just drink the tea and you will both be calm. She sniffed the tea once more and, finding that there was no strange smell the second time, she dismissed it and blamed her nerves. “No, nothing darling, I just thought I smelled something, but it must have been the burnt remnants from the last time Sweetie tried to cook.”

Moonlit smiled and sipped her tea, Rarity followed suit. The tea tasted nearly the same, but there was something not quite right, though the unicorn couldn't put her hoof on what. Pushing aside the odd thought, the unicorn drank deep from her tea cup, finishing off the tea in one, unladylike gulp.

“Pardon me.” The unicorn’s cheeks glew bright red. “I guess I needed the tea more than you did.”

Moonlit giggled. “That’s fine, would you like some more?”

Rarity shook her head. “No, thank you, darling.”

The unicorn’s eyes became unfocused and she put a hoof on the table to steady herself. Moonlit leaned closer, concern in her eyes. “Are you alright?”

She gripped the table tighter and forced her eyes to focus once more. “I-I’m fine, just a dizzy spell I’m afraid. Oh my.”

The unicorn toppled to the floor suddenly, feeling having left her legs entirely. Moonlit leaned down and frowned. She hadn't thought the mare would drink the entire cup in one go. “I’m getting a doctor! Just stay with me, Rarity!”

“Please hurry, I can't feel my legs and- oh stars above.” Her eyes went wide before her head crashed to the floor.

The changeling frowned. The dose should be fine but she was going to be out for longer than anticipated. Thinking quickly, she found a piece of paper, a quill and ink, and wrote a quick note and placed it on the table next to the exit. Whomever would come inside would have to see it and think Rarity was coming down with something and had secluded herself in her room in order to not infect anyone else. At the bottom the changeling added a quick assurance that it was nothing serious, merely a cold or flu and asked not to be disturbed. That was easy enough, now for the hard part.

The changeling made her way back to the unicorn, tucking a pillow from a nearby chair under her head. Next she made her way to the stairs that she presumed went to the second story, which likely held the bedrooms. Once up the curving flight of stairs, the changeling realized her assumption was correct, though there were two extra rooms. One seemed to be an office while the other was a child’s bedroom. Posters of pop idols and piles of unmade clothes littered the room and the smell of a foal covered everything.

That was a potential problem, one the changeling didn't have time to deal with right away. She made her way back across the hall and opened what she assumed was the master bedroom. Sure enough, the large, extravagant room was easily recognizable as Rarity’s and the changeling could even see an open door that contained a small bathroom.

“That's convenient.” She mumbled.

Next she went back downstairs and picked up the unicorn, hauling her back up to her room before closing and locking the door. She added a few protective charms just in case, as well as a warning alarm on the handle, ensuring she would know the second somepony was trying to get in.

She rubbed her chin, looking around the room for where best to store her luggage. In the corner of the room was a large safe, easily big enough to contain her luggage and more. She didn't know the combination, but it didn't matter; one look at the type of safe told her all she needed to know and she slipped her magic under the combination spinner and pulled slightly before punching it hard.

Just like that, the safe opened and she smirked, making a mental note to procure a better one at some point. She opened the safe, expecting jewels or bits, but was surprised when she found small, nearly worthless ones, accompanied by pictures in frames and a scrapbook of some kind. The changeling frowned; did the mare not have any bits to speak of? Or perhaps she used a bank? No matter, she thought. Pushing aside the keepsakes, she made room for her luggage and squeezed it inside before closing the safe and placing a few more wards and charms on it. That would keep anypony out and, if they did open it, they would find a nasty surprise in store for them. The last few spells had drained her love reserves dangerously low, but that wouldn't matter soon enough.

Finally she picked up the unicorn once more and got up onto the bed, slipping under her and wrapping her own hooves around the limp ones of her host. The changeling snickered; that word was going to take on a whole new meaning in a matter of hours when the connection was complete.

She snuggled close to the unmoving unicorn, fitting her body as snugly and as close as possible before taking a deep breath. What came next was going to be as disturbing as it was painful and she was not looking forward to it. She, like every other changeling, knew of the dark rituals and painful metamorphosis that could fuse their being into another, but it had not been attempted in generations, having been all but outlawed by Chrysalis as a taboo that could not be crossed.

Not for the first time the changeling considered abandoning it all and using the egg on herself. It would be hard, but eventually she could birth the queen herself. That would only lead them into more hardship though and, despite not wanting to admit it, she knew her mother had been right. They needed something new, different, and a way of doing things that noling had ever tried.

She tightened her jaw and cast the force field over herself and Rarity before quickly casting an air spell on the pony. Nothing could escape the field, which was perfect. Next she set the field to slowly shrink as resistance fell, meaning solid flesh would resist the field without difficulty but liquid would be forced down, the field pressing against it mercilessly until it met a solid object once more.

The changeling sighed one final time, now burning her last remaining love stores so she didn't need to breathe. Finally, the changeling reached down within herself and touched something primal, something a changeling hadn't been forced to use since the failed invasion: the suicide switch. One of the most powerful defences an infiltrator had, the switch would liquify the changeling completely within minutes after knocking them unconscious in seconds.

One last thing remained before she could activate it and the changeling’s horn glowed brightly as she reached out and grabbed at the unicorn’s mind, altering it to better suit its new host and creating a small new section that would house an additional consciousness and resonate psychically to the changeling’s unique physiology.

Pain spiked through the changeling’s mind and she was dimly aware of the fact that she had burned through the last of her love and was now burning her very essence to charge the spell. Her chitin cracked and more pain lanced through her body. Finally it was done, the unicorn’s mind was altered and it would instinctively pull at the changeling, using her essence to alter itself and Rarity’s body to fit the changeling’s desires. More changes would have to be completed after the joining; the changeling lacked the resources and time.

After one last check of her work, the changeling clenched her teeth and reached inside herself once more, instantly finding the ‘switch’ within herself. This was it. “Goodbye, mother.” She whispered to no one.

The psychic switch was flipped and within moments the changeling fell into unconsciousness. Her body began to dissolve within minutes, the already cracked chitin dissolving first to reveal bare organs and muscle beneath which eventually dissolved as well. The field reacted shortly after, squeezing down on the now-liquid remains of the former changeling.

Bright green liquid flowed around the unicorn’s body before being forced into every orifice at once. The liquified changeling flowed through Rarity’s nostrils and open mouth, into her ears and eyes but it was not enough, there was an entire changeling’s body worth of liquid to go. The changeling flow slipped inside her pussy, easily filling the mare’s passage and seeping into her body from there. Even that wasn't enough and the pressure built until more of the changeling flowed into the mare’s tight anus, stretching and filling the mare’s intestines and seeping into her body. Next her womb parted, allowing the flowing form of the changeling access to the deepest recesses of her body.

Her womb filled to capacity within seconds, making the unicorn appear as though she was several months pregnant. Adding to this fact was her quickly distending stomach that pushed her already pregnant belly larger still. Endlessly the unicorn seemed to grow, her stomach and womb stretched far beyond what they should be capable, and still there was more. Rarity’s body went into overdrive absorbing the changeling, pulling the liquid through every pore it could, drowning its native cells in changeling ones.

The unicorn began to glow, her body’s magic trying to naturally reach a state of harmony with the foreign cells. The ritual knew this and indeed counted on it - with the manipulations done already, instead of destroying the changeling cells, the unicorn’s body actively tried to incorporate them into itself.

By now her belly had grown enormously, having been forced to stretch until she looked ready to give birth to triplets. The green liquid had dissipated and within minutes the unicorn had pulled in every last drop of changeling.

Hours passed and eventually the unicorn’s belly slowly shrunk, the changeling having infiltrated every last part of her body, fusing with the unicorn forever. The mare’s ruined holes winked and tried to close but they could not; the stretching had been too much for the relatively unchanged body and they were left gaping.

Eventually, Sweetie Belle came home and, after seeing the note, wisely chose to slip back into her room silently, remembering all too well just how grumpy Rarity had gotten the last time she had woken up the sick unicorn.

The next day came and, in the wee hours of the morning, the forcefield dissipated and the breath spell ran out, leaving the still-unconscious unicorn hybrid to cough and sputter until it found it filled its lungs once more, this time not with liquid changeling.

Within the unicorn hybrid’s mind stirred a new personality, and with it a question. The changeling had never had a name that had not been borrowed, but she couldn't refer to herself as the changeling or infiltrator or her old identity. She needed something new, something close to Rarity’s name but still distinct so the former unicorn’s mind did not feel too off put by it. Illusive. A sense of pride welled within her walled-off part of her mind.

She knew that within minutes the wall would fall and their minds would be linked forever, so she took the last moments of privacy she would ever have to run over her plan.

Change the unicorn’s body to fit the egg.

Build up a backstory to explain her size increase.

Go on vacation somewhere so she didn't need to explain why she would grow far larger than what’s normal.

Keep up her disguise.

Keep Rarity’s mind placated.

With that done she felt her new eyes begin to move beneath her new eyelids and she felt the presence of her new ‘partner’ begin to stir.

What happened? Where am I? Rarity thought.

We are in bed, we had a slight fall but that kind unicorn, Moonlit Melody helped us to our bed. Illusive thought back, sending positive waves of reassurance to the other part of her mind.

Panic tried to well within their connected mind but Illusive forced it back down. Shh, there is no reason to panic. Let's think about this logically.

Right, of course. Who, or what, are you? Rarity asked, unsure if she was going to like the answer.

Who am I? I am you. I have always been there. Watching, waiting from the moment we were born. I have existed all along, but the fall seems to have allowed me to speak to you for the first time. You may call me Elusive.

... Begins To Bear Fruit.

Rarity felt an intense spike of panic shoot through her and, despite something pushing against that feeling, it was too powerful. She cast aside her blankets and tried to hop out of bed only to tumble to the floor with just a sudden subconscious jerk of her head saving it from bouncing off the floor.

Please, stay in bed. We are hurt and most likely have a concussion. You will not help us by giving us another one.

No, this is wrong. There shouldn't be a voice in my head! You are the nightmare, or perhaps another foul creature and I will stop you!

The mare tried to push herself into a standing position, but she felt remarkably heavy and her uncoordinated limbs flailed around uselessly. Even her magic sputtered, the usual color gone, replaced by an odd mix of teal and green. It flickered for a few seconds before shutting off completely, leaving her helpless.

Rarity, please, I am only trying to help us! At least wait until we have our bearings before charging down the stairs. We could get hurt!

Stop saying we! We are not one and the same! I am going to find Twilight and she will fix this!

The mare pulled herself by her forelimbs across the floor and towards the door to the silent disapproval of the voice in her head. She stumbled up to her knees and reached for the door, only for her hoof to slip off the handle and leave her tumbling back to the floor in a panting heap.

Why am I so heavy?

It’s likely an after effect of hitting our head. We should lie down and get a chance to heal before doing anything reckless.

Rarity growled, forced her sparking horn to form a telekinetic field around the door handle and wrenched it open. Pulling herself down the hall by her forelegs, Rarity gulped, looking down the long winding stairs that led to the first floor.

Please, for the love of Celestia, do not go down those stairs. We are going to get seriously injured, and this time there will not be a random pony there to save us! Just stay here for at least a few minutes.

Gritting her teeth, the mare put one hoof on the step only to find her other foreleg paralyzed.

Just, ask me something! Something only we would know!

Rarity stopped and lay at the top of the steps, panting.

No.

No what?

You can probably see my memories or something. It doesn't prove anything.

Ellusive’s semi separate mind moved quickly, creating a false memory as fast as it could while the mare tried to pull herself towards the stairs.

Think back to after the nightmare! Remember the meeting we had with our friends and the princess?

Rarity stopped, her mind suddenly flowing back to a hazy memory. In it she remembered her and her friends asking Luna many questions about her time on the moon over a light afternoon tea. The conversation hadn't started that way, but after Rainbow Dash spat out the question:

“What was it like on the moon?”

Things had spiraled from there and Rarity couldn't help but ask if she remembered everything from her time as Nightmare Moon. Sure enough, the dark alicorn had shook her head and sighed.

“It's a blur, time moved faster and our minds were only partially joined. I could sense what she wanted to do and knew some of her most recent memories and vice-versa, but that was it.”

The memory faded and Rarity’s grip on the top step loosened. Why didn't I remember that until now?

Had it been important otherwise?

Rarity grumbled and admitted that no, it hadn't mattered at all and she wouldn't have even second guessed the princesses’ assertion. Then what exactly are you?

Like I said, I’m you. The gut feelings you get, the strange thoughts that sometimes prompt inspiration. I don't know how, but suddenly I could think and speak to you after we passed out.

What exactly happened? You mentioned a fall, but I don't remember anything like that. The last thing I remembered was talking to that unicorn and then nothing.

That's normal. When you hit your head hard enough to cause a concussion it often disrupts recent memory.

That doesn't sound like something I would know…

Everything you only half remember or have only heard in passing is all in our head and only I can access it.

Now that really doesn't sound right.

I found out while you were unconscious that I can bring back memories, things that have been forgotten by your conscious mind but have not wholly left. Like when we took a train to Canterlot with Twilight and she had been reading that book on the brain and rambled on about the entire ride.

A brief memory of Rarity looking out the window as the lavender alicorn rambled about useless trivia about the brain came to the forefront of her mind, and she was forced to admit that it did seem likely.

The mare sighed and slumped to the floor in defeat. What happened then?

We heard a crash outside and rushed to the window, only to slip on some spilled tea and crack our head on the edge of the counter. After that we passed out, though it feels like we had healing magic used on us as I can't feel any lingering pain in our forehead.

Rarity ran a hoof over her forehead, imaging that moment her head impacted against the counter and frowning. Sure, it was a little raw and felt a little funny, but nothing close to the amount of pain that running full tilt into a marble countertop would give.

That makes sense. I should still see a doctor, though.

Of course! Just please lay in bed for a little while longer until we gather our bearings. And don't fall asleep!

The mare stopped turning and cocked her head. Why?

Falling asleep with a concussion makes things worse. If you don't believe me then ask a doctor when we get to the hospital.

Fine.

Elusive fell silent, relieved she had talked her partner into not doing anything crazy and giving her more than enough time to construct the memories necessary to convince her they were one. The mare crawled to the door and into her room and, though it pained her greatly, she slowly lifted herself to her bed and sighed.

There, I’m back in bed. Do you remember if Sweetie came home?

I’m not sure, we were still unconscious.

The mare turned her body towards the edge of the bed only to find herself paralyzed and an annoyed voice ringing in her head. What are you doing now? At least yell for her first. If she sees us like this she is going to panic.

Rarity was forced to admit that the voice did have a point and she yelled from her bed. “Sweetie! Are you there?”

She waited, silently as the seconds ticked back. Just as she was about to yell again she heard something fall downstairs and winced when she heard something heavy thump to the ground.

“I'm okay!” called the voice of her sister, which drew a sigh of relief from the bed bound mare.

“Could you come up here for a second, Sweetie?” Rarity called.

“Uhh, give me a sec.” Responded Sweetie.

Elusive and Rarity waited in silence while Sweetie clambered up the stairs and hesitantly poked her head inside their room, looking at them with guilt in her eyes.

She was probably trying to steal cookies again.

Why do you think that?

That guilty expression, the thump sounded like she was balancing on something and it fell. Oh, and the fact that she has cookie crumbs on her right foreleg.

Rarity glanced down and noticed the same thing Elusive had, rolling her eyes at the sight.

“Sweetie, were you in the cookie jar again?”

Sweetie twisted her hoof awkwardly and looked away from the unicorn. “Nooo.”

“Sweetie…”

The foal’s eyes fell and she frowned. “Maybe.”

We should probably discipline her, that cookie jar was on the top shelf. She could have been hurt.

Rarity sighed and reluctantly admitted that the voice was right, again.

“Did you hurt yourself?” Rarity asked

The foal gulped and shook her head.

“Did you break the cookie jar?”

She nodded and looked down, eyes watering.

We should forgive her but ground her from eating any sweets for awhile.

Rarity opened her mouth to speak only to stop. Yet again the voice had offered a better solution than she had thought. Her first instinct had been to ask Sweetie to clean it up but dealing with broken glass was something best left to adults.

“I forgive you Sweetie, but you’re grounded from any sweets for a week. And please, don't try and clean it up. Once I’m feeling better I will do it, okay?”

The foal nodded weakly and took a step back. “Are you sick or something?” She asked.

Rarity forced a gentle smile to her lips. “No, I just bumped my head and need to rest for a bit. I will go to the doctor’s once my balance returns.”

Sweetie’s eyes lit up. “Are you sure you’re okay, Rarity? I could go get nurse Redheart or Twilight.”

Rarity opened her mouth to speak, ready to accept help, only to shake her head. “No, that's fine. I’m feeling a lot better, just a little dizzy is all.”

Sweetie nodded. “Can I still play with my friends?”

The older unicorn smiled. “Of course. Just be safe, and be home in time for supper, okay?”

“Kay.” The foal trotted towards the door only to stop and smile at the unicorn. “Thanks, Rarity.”

The outpouring of love from the young filly flowed into the unicorn and made her feel lighter. “Remember; no sweets, alright?” Rarity added with a shake of her hoof.

The foal nodded and scampered off. Once her hooves reached the bottom of the stairs, Rarity sighed and settled back into bed, pulling the blanket up to her chin.

Rarity wondered why she hadn't accepted Sweetie’s offer to get Twilight, or at least mention Elusive.

Would she even believe you?

I suppose not. What do we do now?

Just relax, I guess. Maybe pick something to read? I suppose we could talk as well, but I don't think you want to do that.

Rarity frowned, she was getting rather annoyed at the fact that the voice in her head was right so often, and the fact that it was her own voice was especially strange. Reluctantly, she looked over to her nightstand and grabbed a romance novel she had started the other night and opened it. Though she was tempted to use her magic, she resisted the urge and used her hooves, not wanting to risk a stray spark lighting her book on fire.

She was also a little curious as to why her magic was doing that, but she quickly remembered Twilight mentioning something like an unfocused mind having trouble using magic, which made sense to the unicorn as magic was directed by the mind and, if it took damage, the effects of magic were different.

She plucked out her bookmark and began reading, though she was hardly even aware of the words before her eyes as her thoughts were elsewhere. Eventually she felt strong enough to try a little telekinesis, and after lifting the bookmark and the book, she put the mark back inside and put the book back on her nightstand, having retained nothing from her brief time reading.

I think we are strong enough for a walk down to the doctor’s, if you want.

I think… that I’m okay now.

The voice sounded confused. Are you sure? It wouldn't be too hard to stop at the hospital and get us checked.

Rarity shook her head and cast off her blankets. No, I wouldn't want to be a bother. Besides, I don't think they can really do anything for a blow to the head besides prescribe bed rest and relaxation.

Her hooves landed on the floor with a heavy clunk and she stood up, barely even noticing the added weight. Elusive smiled triumphantly, or at least imagined herself smiling as she no longer had a face. Her host’s memories had been altered enough that she didn't notice weighing as much as two ponies of her size and in addition, Elusive had managed to isolate her magic enough that they no longer mingled. It was a small touch, but it would make Rarity unable to use changeling magic unless Elusive willed it and made regular magic use easier on the mare.

She merely watched through the unicorn’s eyes as she made her way downstairs in order to make herself breakfast, having been made aware by a faint grumble coming from her stomach that her incident had made her skip supper the day before. The changeling part of her mind was rather amused by the feeling of hunger as she had absorbed all of the familial love from earlier and no longer required sustenance, and a desire for hard food was a foreign one.

Still, it would be nice to taste food again, and now that she had both a set of organs to break down emotions and one to break down food, it would be a novel experience to say the least. While Rarity cooked her eggs, made her toast and set aside her jam, Elusive was hard at work. Familial love was incredibly potent, especially since it was pointed at her. This gave the parasitic changeling more than enough energy to begin to work her next set of changes.

Rarity was unaware of any of this, her segmented mind not able to hear the machinations of Elusive. She merely ate her breakfast quietly, trying to think if she needed anything done or not. It was… what day was it? She glanced at the calendar and, with a sigh of relief, noticed it was Saturday.

Which meant she didn't have to tend to the shop. Though she was tempted to work on a few orders, they were not due for weeks and she had plenty of time. What could she do then? She forked another load of eggs into her mouth and chewed silently.

She briefly considered making an appointment with someone to talk about the voice in her head, but by now she was almost completely convinced it was actually a part of her. It knew everything she did. It acted just like she did, and seemed more generous than Rarity was.

The piece of toast briefly wavered in the air, her magic floundering for a second as she briefly considered that she might be the infectious thought, only to shrug that idea off. There was no way she was the other entity, right? She knew she had control of her body, but she had also felt herself move and freeze occasionally as well.

She gulped, forcing the thought away and taking a bite of her toast and raspberry jam, hardly noticing the taste as her mind turned a million times an hour. Elusive would have laughed at the mare’s train of thought if she was capable of it and, though she was tempted to try and push this idea that Rarity was the parasite and maybe even convince her to let Elusive have control of their body, that wouldn't work in the long run. The changeling had no idea how to walk, talk and act like Rarity. Sure, she might be able to mimic it for a while, but what better mask was there than one that wasn't a mask?

All the while Rarity ate, she had begun to grow warmer. At first she had attributed this to simply waking up, but as time went on, she felt the heat begin to centralize between her back legs and she couldn't help but squirm in her chair. Her heat wasn't due for another week and she grumbled as the heat slowly built, ignoring the impossibility of it existing. Rarity sighed and wondered if a spa day was in order, one complete with a happy ending.

She gulped down the rest of her meal and put her dishes in the sink. It was possible; she had the money and the time and no longer had to look after Sweetie, at least for the moment. In the end she shook her head. The last time she had taken up Aloe and Lotus’ special offer she had ended up spending way more than she had set aside at first, and besides, she had toys at home.

As reluctant as she was to use them, Rarity nonetheless felt like a little ‘alone time’ was in order as the heat had continued unabated the entire time she had finished eating. Making her way to the stairs, Rarity was startled out of her lust-filled reverie by the familiar feminine voice of Elusive.

Where are we going, Rarity?

Rarity blushed, suddenly realizing what she had been about to do while the question of another voice in her head had yet to be solved.I was, ah, about to relieve this heat, but I just realized I should probably start on that order for Mayor Mare.

The order that’s not due for another two weeks? The voice asked incredulously.

Well, it would be nice to get it done early.

You know how hard it’s going to be to concentrate, don't you? Let's go find that relief you had been looking for first.

The mare found herself facing the stairs once more, a hoof on the bottom step, but she didn't continue. She didn't remember turning back around or starting up the stairs until it suddenly came back to her that she had admitted that Elusive did have the right idea and her sudden appearance hadn't mattered.

Yes, that sounded right the unicorn. She made her way up the stairs and into her room, locking the door firmly behind her and drawing the blinds. She didn't like the thought that any random pegasus could pass by and see what she was doing. Taking out the candles didn't take long, and neither did lighting them and arranging them around her bed.

Rarity stopped, breathed in a lungful of the scented smoke and enjoyed the aroma. Just because she was going to take care of a more carnal desire didn't mean she had to debase herself. Why, after this she planned a long, hot bath with a good book and maybe a few of those cookies Sweetie had tried to steal.

She breathed a long, lusty breath, the heat between her lungs becoming nearly unbearable. Something felt off about the entire situation and a small part of herself screamed that she should deal with the voice in her head before masturbating, but even at a scream the voice was small, barely above a whisper compared to the burning lust that welled within her.

Elusive would have smiled; the mare was falling to her base urges quickly and the changeling had gotten remarkably good at touching the right centers of the mare’s brain and hitting all the right cues to make her more susceptible to suggestion. The mare was currently reaching under her bed and extracting a small wooden case with a latch on the front. Flipping it open revealed several small toys.

One was a simple plastic cock, barely big enough to satisfy even the most petite of mares. Next to it was a slightly larger vibrator, and dwarfing all three was a monsterous white plastic sex toy that had the words the alicorn written on the bottom. Elusive very nearly snickered at the sight, and, judging from the rather emotional response from the mare’s body, it was something of a favorite of hers.

Rarity’s hoof hovered over the vibrator for a few seconds before a powerful urge overtook her and she grabbed the enormous white one. A small giggle escaped her lips and she whispered. “Feeling frisky, aren’t we?”

We feel the same things, and we feel empty. Elusive added the extra weight of another flare of lust to the word empty, and Rarity, like usual, was forced to admit that the voice was right. She felt positively empty, and only the alicorn could fulfill that need.

After hoisting the mammoth sex toy from the box, Elusive noted that a decently sized deep blue butt plug was hidden underneath. As an afterthought, Rarity grabbed it before tucking the now-resealed box back under her bed. Elusive didn't even have to look into Rarity’s memories or use her eyes to know that the butt plug was called the little sister.

Rarity hefted the toy up to the bed and, with a light use of magic, sealed it to her headboard. The mare placed a small kiss at the head of the toy and moved to grab the bottle of lube she had hidden behind a picture frame of her parents. She went to apply the lubricant, only to stop and reach between her legs.

“Stars above.” She brought the hoof up to her face, shocked at just wet she had become.

She tossed the lube back on the end table and shrugged; though it was odd not to need it, it also wasn't a bad thing, right? She shook her head - it didn't matter. This may be an odd heat, but it was still just another one and one ride with the sisters was usually enough to satiate any heat.

Usually the mare would lavish the fake cock in kisses and talk dirty to it, as if Celestia and Luna were there in her bed, ready to ravish her. Today was different, the heat had come on suddenly and intensely, and she had no time for the usual pleasantries that she usually paid to the fake cock.

She lined up her surprisingly plump flanks with the toy and gently pushed back. The head was large and flared, which made initial insertion difficult, but Rarity knew from experience that it was worth the extra effort as the feeling of having that huge flared head press against her cervix was unlike anything she had ever experienced in her entire life, one made better with Luna fit snugly inside her other hole.

With a little more pushing, the flared head was pushed just inside the mare’s tight pussy, helped along by the veritable flood of juices that leaked from her. With the toy now snug inside, she moved her attention to the plug.

Elusive had to admit that she was impressed; her host was a talented size queen, which would make the insertion of the egg much easier. Perhaps she could even do so today? It would speed things along nicely, and the gestation of the egg was almost a full year anyway, so she would have months to prepare a cover story and convince her host of it. Nevermind that the tsunami of self love that she could pick up on from this session alone would power the changeling’s plans for days.

A plan bloomed in the changeling’s partitioned mind as she watched the mare lather her plug in lube and gently begin pushing it inside herself. Elusive couldn't help but blank for a moment, the pleasure was strange and it seemed as though her host enjoyed anal immensely as she seemed mere moments from her first orgasm. The changeling couldn't help but feel a little giddy at that. Her host was a bit of a slut, with a penchant for double penetration and a size queen to boot. It wouldn't be hard to convince her to lay a random stallion in the coming months and convince her the egg was her foal. Until then all Elusive had to do was change her perception so she didn't notice the bulge in her belly and to wear a dress, and her plan would be perfect.

Thoughts, plans and ideas flew out the window as the changeling felt the thick plug suddenly fill their asshole. “Mmm, that's good, stay inside me Luna dear. I need to lavish your sister with some attention as well.” Rarity muttered.

Elusive couldn't help but moan through Rarity’s mouth as her pleasure was their pleasure, and this was by far the most enjoyable physical sensation the changeling had ever experienced. She felt her already tight pussy become tighter still as the sheer size and length of the plug pushed against its sister through the thin walls between her ass and pussy.

The second Rarity moved back, pushing her weight against the toy in her snatch, Elusive felt their orgasm and was temporarily lost in the sea of pleasure. She had to hand it to Rarity, the mare knew pleasure better than most.

Rarity herself seemed less moved by the orgasm and, despite her legs quaking and a stifled moan escaping her lips, she still pushed back back against the alicorn, intent on finally relieving the sense of emptiness within her, a feeling that Elusive made sure to amplify more and more, empowered by the self directed love that quickly filled her love reserves until the point that they felt mildly bloated.

The mare hardly noticed it, but Elusive was painfully aware and she pushed as much power as she could from her love stores into furthering the changes and adding fuel to the already raging inferno of lust that burned within them. A faint green glow surrounded their horn and, if either being was paying attention, they would have found that the back of their body glowed a sickly light. Elusive was too busy focusing on working her changes and Rarity was completely and utterly gone, her mind consumed with the need to be fucked and filled, something she felt as though she was making headway on until now.

Even with the attention of both the alicorn and the little sister, her holes still felt empty, which was bizarre as this was usually her breaking point - the moment where her body was stuffed so full that it was the reason she did her special stretches, to ensure she stayed tight. She needed more, something bigger, something deeper.

The mare growled and pushed back, walking backwards in order to stuff every last inch of the toy inside herself. She didn't think how strange it was that it fit so easily, or that it usually took nearly twenty minutes of working the toy in and out of her to get to this point. She didn't think of anything at all save for the undying need that had flared inside herself.

Her butt impacted the headboard, which sent another shiver of pleasure through the unicorn/changeling. They both stopped for a moment to enjoy the sensation of the flared head impacting with their cervix, but it was only for a moment. Rarity was already close to another orgasm, but that was a distant thought. The heat had graduated to an itch, one that was scratched a little by the impact of plastic cock with the entrance to her cervix. However, it was not enough to cure that itch and, growling in annoyance, the mare shifted forward and slammed her hips back.

The sound of their flanks smacking wetly against the headboard was a pleasant one as it came with a hard impact of the toy impacting with the deepest reaches of the mare’s snatch. The changeling burned and burned all the self-love, which only seemed to make the speed at which the unicorn generated it to increase as well. Rarity moaned and growled in mindless abandon, slamming her hips back over and over, her juices running down her legs as her body was put into the deepest heat of her life.

An orgasm came and went, adding even more liquid to the river of arousal that flowed down her back legs. Reluctantly, Elusive enlarged their shared emotional stomach, only for it to fill up within seconds. Now with more energy than she knew what to do with, Elusive quickly began enacting any changes she knew would take a lot of said energy.

She strengthened their bond, interlacing their shared consciousness and connections between the two different bodily systems built into their body, a difficult and consuming task that ate up most of their love… which was quickly refilled when the mare threw back her head and moaned loud enough for even the distant neighbors to hear. The wet smack of their ass against the headboard had grown louder as the mare pushed back with greater abandon, not caring if she broke the headboard or the wall behind it.

Elusive felt their enlarged emotion stomach begin to fill past the brim once more and, in a snap decision, she diverted it all into their bones, strengthening them with changeling magic and turning them black. Thankfully that should eat up all the energy the mare could possibly produce, and not for the first time Elusive marveled at just how much love ponies could produce, even when directed at themselves.

Rarity, meanwhile, was unaware of their changes. Sure, she felt her body shift and move a little, her guts seemingly rearranging themselves, but that was infinitesimal compared to how much attention she poured into her breakneck speed. Her back legs shook from exhaustion, her breathing came quickly, and she was pretty sure she had bruised her flanks after she pushed back particularly hard a few times.

None of which mattered and she growled. “Why isn't this helping? I’ve cum four times already!”

Finally, she stopped. Her butt was flush with the headboard and her mind was turning a million times an hour. Should she stuff the other toys inside herself at the same time? No, they might get lost and she was not keen on going to the doctor to get them removed should she lose them inside herself.

You know, we could always get the big toy from the safe.

Rarity’s ears twitched and she glanced over to the safe. She didn't remember a big toy, until suddenly she did. It was a huge green egg that was meant to be inserted into her aching cunt; how could she have forgotten about that?

Brilliant idea, darling. Let's go.

The mare pulled the alicorn from her headboard and held it inside herself with her magic. She wasn't satisfied yet, but the alicorn and the little sister would have to do for now. Stepping down from the bed was awkward, but thankfully, with Elusive’s help, they made it over to the safe after only a brief stumble.

Rarity couldn't help but feel thankful to the voice; it was still strange that it existed, but it had been only helpful so far. She reached up to the safe and spun the dial three times, opening it to reveal the huge egg from her memories. It was almost as big as her head and tapered up to a slight point; obviously intended to go in that way first. It was green and small veins ran along it, though that wasn't the strangest part. Inside she could see a faint green light pulse from within and, for a second, she thought she could see the outline of something inside it.

That was silly, though; there was nothing inside it, it was just a sex toy after all. A strange one, yes, but still just a toy. Not sparing another thought to the strangeness of it all, Rarity lifted the egg out and closed the safe. Carefully, slowly, the mare carried the egg back to the bed where she placed it on the bed’s center. The toy was strangely slimy, and now with it outside of the safe, the mare realized how large it was.

She gulped, unsure of herself for a moment, only for a wave of emptiness and heat to flare within her and wash the doubting thoughts away. First, she pulled the little sister from her tight hole. It took a bit of working, but it finally popped out of her and was placed on the crowded night stand. Next she slowly withdrew the alicorn from her now quite loose cunt and tossed it aside, all decorum on ensuring it didn't break forgotten as the emptiness was now unbearable.

Hovering her gaping lips over the egg, Rarity wondered for a second how strange it might appear for her to take such a huge thing inside her. Like the last time, this thought did not linger for long and it only took a gentle prodding from Elusive to make the mare drop her hips. The instant she felt the surprisingly soft and rubbery flesh of the egg to touch her cunt she shivered. There was something strangely… religious about the experience. She didn't have the words for it, but it felt oddly important that she fulfill the ache within her.

Rarity didn't care about that though and slowly settled her weight onto the top of the egg, her lips parting surprisingly easily and accepting a few inches of the egg’s tapered top. The relief she felt was palpable, but it was only a taste of the relief the huge egg would give her and she knew it. If only a few inches gave her such a feeling, she had no doubt that a few more would bring her to her next orgasm, and maybe then the heat would die down a little.

Elusive kept a careful watch over the mare’s muscles, easing pressure here and increasing it there, ensuring the egg would not break. It was durable, flexible, and would be difficult to damage, but any undue application of force at a certain point could potentially split the skin or damage the half-formed larva within, which was not something the parasitic changeling would allow even the chance of happening.

Shifting lower, Rarity giggled, her addled mind only half aware of what was going on but ultimately uncaring as to what was happening her - the heat was being quenched and that's what mattered. She slid lower, her lips parting far wider than what should normally be possible for a pony without irreparable damage. The mare didn't notice this though, and if she did, it was unlikely she would even care. All that was relevant to her was getting this toy inside her and getting rid of that clawing emptiness within her.

Their shared body made it lower and lower until only an inch remained to the mid way point of the egg. The hardest part was coming up and Elusive wasn't sure if she had given enough time for her changes to take effect. Brute forcing them with energy was fine, but without giving the mare’s body time to adjust and accept them, it could lead to failure. She had come too far to stop now and, unless Rarity took the egg, it would be difficult to change her recent memories enough to explain why the egg was still there and what had happened.

By now neither half of their mind needed encouragement and, despite the sheer amount of stretching occuring to Rarity’s once tight hole, she pushed on. She could feel the egg mere inches from her cervix and something about that sent a foreign feeling of accomplishment and arousal. Merely settling her weight against the egg was no longer enough, she had to begin to push down against it, using her strangely powerful muscles to force more of its size inside her.

Her body ached, pain spiked from her tortured nethers but the relief, oh the relief, was palpable. She could feel the heat begin to ebb slightly; though it was not enough to return her senses, it was potent and she craved more.

“Hrrrn.” Rarity grunted, feeling the lips of her vagina being forced wider than she would have ever thought possible.

Elusive worked quickly, pouring chemicals into the mare’s body that would ease her pain and relax her muscles, allowing the egg to pass easier. The chemicals took affect almost immediately and, with a startled gasp, the pair felt the egg slip past its widest point and several more inches inside their body.

“Eep!” Rarity squealed, feeling the egg bang into her cervix. Her lips quickly curved into a moan and she came again. She wasn't sure how many times she had cum already but she knew that number would only grow before she was done.

The pleasure was unlike anything mare or changeling had experienced and it was only rivaled by the desire for more. The pair planted their back hooves down and pushed the last few inches inside them, which had the effect of pushing the tapered end of the egg into their womb.

The pair grunted in exertion, the pleasure was still there but the pain had returned in force; this time it was not their stretched and distended pussy that cried out, but rather their womb. Elusive had made sure that their womb was large enough to contain the egg, but it would be a far more difficult task to force it inside. Usually, a second changeling was there to help, using their hooves to shove the back of the egg deeper, but now that they were relatively alone, Elusive would have to get creative.

Looking around, she noticed the bedpost had a wide flat end on it that extended up nearly a foot from the rest of the footboard. Perfect, the changeling thought.

Control was relatively easy to take from the mare as her drug and hormone addled mind saw Elusive as a part of herself. Keeping one hoof between her legs in order to keep the egg in, Elusive maneuvered their body over to the bedpost and hoisted their body up. The unfamiliar sensation of having the egg twist inside them was strange and the pair caught a glimpse of their distended body, the sheer size of the egg making her abdomen stretch and grow to accommodate its size.

Rarity’s eyes lingered over the spot and Elusive felt a spike of endorphins surge through their mind. Maybe it wouldn't be so difficult to convince the mare she would enjoy this, after all. Thoughts of motherhood and responsibility floated through their mind but were pushed away; there would be time for entertaining those thoughts later. Now she had work to do.

She pushed down on the bedpost, testing whether or not it was strong enough for what she had planned. The thick wood didn't budge and it seemed more than capable of taking her weight with ease. With the head of the post placed against the bottom of the egg, Elusive gently began to drop her weight down on the egg.

“Ooooh sweet Celestia.” Rarity moaned, her eyes rolling into the back of her head.

Elusive was temporarily overwhelmed by the rush of pleasure that surged through their mind, though she had enough sense to lock their back legs up to make sure they didn't fall. After coming down from the brief but powerful high, she placed her forehooves on the footboard and pushed down once more. Her pussy was stretched wide as the foreign object slid inside herself and, surprisingly, her cervix was able to stretch enough to allow the massive object entrance.

It wasn't until they once again met the halfway point that trouble began to arise. Her cervix could stretch enormously, but they had long since passed the diameter that a normal pony birth would usually allow and Rarity could feel as though she was nearly at her limit. Whimpering pathetically, the mare shuffled nervously, unsure of what to do. The pleasure was enormous, the pain was minor and the heat had died down somewhat, but a part of her mind remained resolute that another push would give them relief and usher in pleasure the likes of which no mortal had experienced.

The changeling half of their mind had done all they could, and only one last healthy dose of a pain numbing agent could help them now. Elusive wondered if she would need to give Rarity any more encouragement before she felt their hips lower and a spike of pain ram into their brain. The egg slid nearly completely inside their now overfull womb and they both let out a squeal of surprise and pain at the sensation.

Pleasure washed away the pain, but not quickly enough - they needed more. They were close, incredibly close, and it would only take one last push to get there. Despite Elusive’s reluctance to rush ahead so quickly, Rarity asserted dominance of their body and pushed down one last time.

With an audible wet sound, the egg found its home in their womb and Rarity’s body began to twitch madly as she had the most intense orgasm of her entire life. The mare got off the bed post, only to topple to the bed in a heap. Elusive was no help in this matter as she had already gone to work healing their stretched cervix and sealing the egg within their body.

Together they twitched and spasmed as pleasure wracked their body. Rarity mumbled madly, her already-scattered brain being tossed to the wind amidst a mad surge of conflicting signals. The boost to their shared reserve of emotion was immense despite the energy draining task of reinforcing their body. So immense was the sudden flood that a multicolored ooze surged from between their lips, staining their muzzle with the distinct flavor of love-tainted lust.

Elusive panicked and used the overflow of emotion to shut down Rarity’s consciousness through brute force. Thankfully the mare didn't fight back and Elusive was granted control of their body once more.

Now in control, Elusive brought her hooves up to her lips and stuffed all the emotion back into her mouth where she swallowed it and carefully guided it with the appropriate muscles into the correct stomach. Thankfully, with the mare’s consciousness now faded to nearly nothing for the moment, the flood of emotion stopped almost entirely.

The mammoth outpouring of love and lust was unlike anything Elusive had tasted and, even with her enlarged emotional storage stomach, she still found herself overful. Thankfully she had a need for all that love as the changeling had to both do extensive rewriting of their memories as well further change their body to suit her needs.

First, Elusive pulled the egg further up into their body, though this was met with a pang of regret; Rarity’s intense love of motherhood having rubbed off on her. Their enormous belly was truly something to behold and the pair looked pregnant with triplets, and ready to burst at that. Elusive chuckled at the sight; between her own overfull emotion stomach and the egg, their body was bloated beyond belief.

The mass slowly dwindled as Elusive rearranged their organs in order to allow their stretched womb to pull up further into their body. It was a strange and frankly disgusting feeling, but it was necessary if she was going to make this work. Next she went about enlarging the mare’s torso slightly. Not enough to make her appear fat, but enough that their two sets of organs and their egg had enough room, the tightness in their midsection alleviating somewhat. Next she put a mental block on Rarity’s mind, making her unable to see their still slightly distended midsection and diverting any attempt to glance at it into an intense desire to wear something that would cover it.

With that done, Elusive pondered what to do with the remaining energy. With all this gathered from a single masterbation session, I am going to have an immense amount of leftover love.

The changeling-controlled hybrid shivered in anticipation. As a spy, her body had been designed to be lithe, built mainly for subterfuge and stealth while her emotional storage was purposefully low and her need of love equally as low. This all helped to further insert herself into pony society as she was by no means a harvester and didn't need to produce an excess of love, save for a small stash for just in case.

She had not always been a spy, though; in another life she had been one of the queen’s guard, and with that sudden memory an idea occurred to her. Her chitin had been tougher than steel back then, her hooves easily able to crush through plate mail and her natural abilities and extra senses had been on par with the queen herself. But the hive had demanded she change and adapt as the love stores dwindled.

Now? Now she had love to spare and she was guarding a queen, which meant she had to give herself as much of an edge in combat as possible while still remaining inconspicuous. It would be difficult and would require planning and an immense amount of love, but if today was any indication, she would have enough of it to feed a hive.

The changeling-controlled hybrid made her way to the bathroom and plugged the tub. With that done, she began to fashion an emotional storage chamber in order to be filled with her excess. In time, the makeshift chrysalis would fill with liquid love and the changeling would would regain what she had lost and become an apex predator once more.

All she needed was time.

I am aware of what some might consider plot holes near the end of the last chapter and begining of this. Those are intentional.
