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.
