A Whole New Twilight

“What is it Zecora?” Twilight Sparkle whispered.

The zebra shook her head and tightened the grip on her walking staff. “That I do not know, but away from here we should go.”

The other girl frowned and leaned down, placing her hands on her knees. “It doesn't look dangerous at least. It's hardly bigger than a dragon egg.”

The zebra frowned, as she continued to inspect the bulbous, fleshy egg which sat in the crook of a tree. “The everfree is home to much danger, each one growing ever stranger.”

“Still. I think it's fair to say that this thing is not the cause of the blight we’ve been investigating.” Twilight Sparkle remarked as she stood back up and brushed the dirt which clung to her leather exploring outfit.

“I know this thing you will want to test, but if you do, I have a request.” Zecora began, her gaze never leaving the pulsing green and purple egg sitting on the ground before them.

“Well I was hoping to relocate it to my lab, as I’ve never seen such a species before…” Twilight muttered half to herself, half to Zecora.

“I simply ask you keep it caged, until its danger can be gauged.” Zecora finished, the zebra taking a step back. “This thing reminds me of something bad, more research will need to be had.”

Twilight nodded and lit her horn, lighting up the area with a bright lavender glow. “I’ll keep it under level three containment, until we’ve identified it.”

Zecora watched as her friend gently tugged the egg free from its crook in the tree and wrapped it with several layers of magic, forming a glowing purple box that encapsulated it completely. “Though your magic is strong, I would still be wary, somethings do not find it scary.”

Twilight nodded. “It will be fine. Nothing short of a null rod would be able to break through my spells.”

The zebra shook her head as Twilight teleported the egg away, leaving them alone in the small grove once more. “Do not worry, I will continue my search. I swear I will not leave you in a lurch.”

Twilight nodded. “I appreciate it Zecora. I am going to head back to the library and begin studying the egg. Just in case it has something to do with this blight we've been hunting.”

“I will continue the search for this blight the rest of the day, and try to remember more about this creature along the way.” Zecora continued, before turning to leave.

“Thank you Zecora and best of luck. I’ll let you know what I discover and will meet back up with you soon.” Twilight exclaimed.

“Remember, though patience and caution may cause you to chafe, they are all that keeps one safe.” Zecora warned before vanishing into the trees.

Twilight Sparkle thought about the zebra’s parting words before ultimately deciding that she had done enough. After all, there were no known creature capable of producing the effects of a null rod, and her wards could contain Tirek at full power. With one final shrug, the unicorn began the long walk back to her library, the being already thinking of where she would start when it came to examining her new specimen.

A smile slowly crawled across her face as she thought of all the possibilities that may lay before her. Research grants, praise from Celestia, or perhaps even a new species named after her. Each possibility more tantalizing than the last. With thoughts of grandeur swirling in her head, Twilight stood tall as she strode through the bush, confident that something good would come of this discovery.

The unicorn turned a page with her magic before yawning suddenly. “This book is duller than my hoof.” She muttered, clopping her hooved foot against the floor in emphasis.

Pushing herself back in her chair, the pony looked up to where the egg sat within a small square levitating just behind and above her desk. The stand it rested on was equally small, but did its job moderately well, ensuring Twilight could see it, and scan it whenever an idea came to her. Something she had yet to successfully do, which caused her to snort irritably just thinking about it.

“How are you able to resist my scans?” She asked the unresponsive egg. “No unthinking entity should be capable of such a thing.”

The unicorn was knocked out of her angry muttering by the door to the basement opening, and a shaft of life piercing the relative gloom of her lab. “Twilight!” A voice called. “Your supper is getting cold. Should I put it in the fridge or just throw it out?”

“Just put it in the fridge. I’ll be up in a few minutes.” Twilight replied, before her gaze returned to the egg, a hand rubbing her chin. “I just need to crack you, without having to crack you.”

Spike rolled his eyes. “I don't know why I bother.” He muttered before closing the door and walking off.

Twilight didn't even notice him go, her gaze so fixed on the egg that she hardly paid attention to anything else. “You may keep your secrets for now, but I will discover what mysteries lie beneath that fleshy, disgusting exterior of yours.” She whispered, jabbing a finger at the egg. “This is just the beginning you gross looking ball of puss.”

The egg did nothing but sit there and pulse occasionally in response to Twilight’s words.

Twilight Sparkle sighed, her head meeting the desk. “Why can't anything in my life be easy?” She muttered, before sighing a second time and picking her head up from her work surface. “Alright book, let's see what else you got for me. Hopefully I won't have to ask quick study about this...”

Twilight groaned, a headache hitting her a second after the neck pain did. The combo did not bode well for her, and it told the girl that she had fallen asleep at her desk before the rest of her senses had even returned. When they did, and she nervously opened her eyes, she found that she had indeed fallen asleep reading at her desk, an open book lying beneath her head.

“Not again.” She muttered, already not looking forward to receiving an earful from Spike, which would no doubt include at least one ‘I told you so’.

The girl paused, an uncomfortable sensation coming from her waist, but she pushed that down for now, as she had noticed something terrible had happened. “It escaped.” She muttered in shock, the egg having cracked open sometime during the night, her wards proving to be not up to the task.

Looking around, Twilight scanned the room intently, only for the uncomfortable sensation to return to her waist, as well as her back. Eyes going wide with shock, she leapt into a standing position and pulled up the skirt she was wearing. What she saw made her heart nearly skip a beat and her mouth to become dry, her mind already churning as panic became all but inevitable.

For around her waist was a thick band of green flesh which completely covered her crotch.

“No, no no.” She repeated as she tore off her clothes and lit her horn in order to summon a mirror.

Now staring into her reflection Twilight realized the true depth of what had happened to her as she found the band around her waist also went all the way up her spine and around the sides of her chest and ending at her nipples. The strip was over an inch wide, and not overly thick, though it clung to her so tightly that Twilight began to wonder if removal was even possible. It was clearly alive as tendrils were already slithering inside of her pussy and ass, and even her breasts.

Grabbing one of the strips that connected to her right nipple, Twilight tried to pull on it, only to find her knees immediately give out, and her arms fall uselessly to her sides. The feeling was akin to having one’s limb fall asleep, and the numbness was all consuming, making Twilight abandon any attempts to remove it physically. Grunting in exertion Twilight pulled herself back up and gave her arms a shake, slowly waking them up, and allowing her to stand on steady feet once more.

“Fine, lets see how you like magic.” Twilight muttered, lighting her horn.

Her first thought was fire, the second was telekinesis, but she didn't like her odds of not getting set on fire herself, and she had already determined that force wouldn't help her here. She wasn't a genius for nothing though, and in a flash of insight she altered the standard teleportation spell to not take into account clothes. It wasn't difficult really, and after a minute she released the spell, teleporting several feet away.

The tightness on her nipples, and the slithering sensation that continued coming from her guts told her it was unsuccessful and a glance down confirmed that. “How?” She muttered before lighting her horn and trying again.

A few more teleportations, and failures later and Twilight Sparkle was at the end of her rope and she let a panicked cry of anguish. “What the fuck are you?” She yelled.

The slithering sensation increased, and Twilight could feel a rather thick tentacle begin to enter her ass. The sensation of being stretched was not a very comfortable one, but neither was it painful, the smaller tentacles from earlier having evidently prepared the way. Falling to her knees, the girl couldn't help but moan, for at the same time that her ass was being penetrated by the thick tentacle a pair of smaller ones were tweaking her clit.

Twilight had never told anyone, but she was a fan of her partners being a little rougher, and this was right up her alley. Unfortunately a little too up her alley, but despite the strangeness of the situation Twilight couldn't help but admit that it felt really good.

“Think Twilight.” She muttered, squeezing her eyes shut. “It's probably been pumping you full of aphrodisiacs, there is no way your enjoying this.”

After her declaration she stood up, only to stumble towards the chair, gripping its back tightly as the tentacle in her ass just kept going, filling her intestines. Her stomach bulged and writhed as the tentacle continued to move around inside her, shifting her organs around with disturbing ease. Gritting her teeth, Twilight lit her horn and looked down, quickly formulating a disintegration spell in her mind.

It was dangerous, but for all she knew this creature was about to start eating her organs like they were little more than cupcakes. Releasing the spell, Twilight aimed it the band connecting to her right nipple, singing a hole straight through it. She was on the ground before she could even scream, the girl feeling like she had just shot a hole through her arm.

It didn't last long though, as the creature twitched, and shifted, the hole rapidly repairing itself and causing the pain to dull until nothing but a dull ache remained. Groaning, Twilight Sparkle made a note of not doing that again, and struggled back into her chair, mind running through all the possible solutions still on the table. She could polymorph it, but given that she could feel what it felt, she was just as likely to polymorph herself as well.

Other ideas were considered and discarded at a rapid pace until she was left with nothing but panic.

“Information. I need information.” She declared, the girl doing her best to ignore the tentacle in her ass which had reached just beneath her stomach.

Grabbing a pen and paper she began to scrawl down a hasty description of the creature, where she had found it, and any other information she thought pertinent to her predicament. The letter was nearly complete before she felt a rumbling from her guts a second before she began to feel her insides start to shift. For a moment it was almost indescribable, a surge of something liquid had briefly filled her before all of a sudden her intestines began to… straighten for lack of a better word.

It was like the creature was fast tracking her entire digestive system, and the girl clutched her midsection as she felt her body get reshaped before her very eyes. Gritting her teeth, Twilight quickly cast the sending spell, hoping that her librarian friend in Canterlot was as fast as she usually was. With little else to do but wait, Twilight began to pace, her gaze being continually drawn to the mirror, and the horrible implications held within.

In an effort to put it out of her mind Twilight hastily put her clothes back on, only to find that the outlines of the creature were visible through the cloth. Grumbling to herself, Twilight grabbed a hoodie and threw it over her shirt, thankful that she didn't need to change her skirt at least. Though out of sight, the creature was hardly out of mind, as its presence was a constant reminder that something was very wrong.

The small tentacles inside her pussy were still present, but they were no longer moving at least, while the one in her ass was also strangely still. As disturbing as the thought was, Twilight couldn't help but admit that she was getting strangely used to the whole thing. Even the feeling of having her nipples penetrated by thin tentacles wasn't enough to make her too disturbed.

A flash, followed by a thump alerted Twilight to the fact that her library connection was as fast as she hoped she was, with a heavy book now resting on her desk. Sprinting over to it, Twilight tried not to think of the sensation of her legs rubbing against the creature and focused on the note which lay atop the book. Opening it up, Twilight read through it in seconds.

This is the only text which refers to the creature you mentioned, though it isn't much. Thanks again for that categorizing spell, it was a huge help.

“Come on come on.” She muttered, opening the book and quickly finding a small bookmark sticking out the top. “Aha, there we are.” She exclaimed.

Flipping to that point in the book, Twilight began to scan the page in search of the information she craved. “That's not it, that's not it, that's not… wait a second.” Twilight muttered before peering closer at the page.

A page which was headed by the title, the mage killer parasite. That alone was enough to make the bottom of Twilight’s stomach fall out and she could already feel panic begin to rise in her guts. “Calm down and read Twilight. The title might be for an unrelated reason.” She reminded herself, the girl hoping against hope that she was right.

Reading down the page, she found the description was short, inelegant, as well as incomplete, but it did contain some hope. The name itself had been gained from the fact that magic couldn't affect it, and that it did not in fact kill its host. In fact it even protected its host from hostile offencive magic, effects that would force its host to be knocked unconscious, and even mind control. In addition, it was stated that upon completion of its life cycle, the creature unnatatched itself from the host with no long term adverse effects.

What was less hopeful was a sentence that informed Twilight that the creature also used the host to reproduce, though it only rarely did so and only after being exposed to a certain plant. Putting down the book, Twilight reclined in her chair, unbothered by the feeling of leaning against the creature which ran up her spine. Letting out a long breath of air, Twilight shook her head slowly.

“It's not going to kill you, nor is it going to do any long term harm. Zecora already said she was going to figure out more about it. All I have to do is go about my day, and wait for Zecora to get back to me.” Twilight told herself.

Standing up, Twilight grabbed her notepad which listed today’s activities. “Alright, lets get through my todo list quickly.”

Grocery shopping.

Assist Rarity with the measurements.

Organize Mayor Mare’s filing system.

Two and three werent required, as Mayor Mare had mentioned that the filing system wasn't going anywhere, nor was it pressing anyway. Rarity was available today, but she also had time this weekend to figure out her dress for the gala so that could be moved back until this whole situation was figured out. Leaving only grocery shopping, a job she could easily delegate to Spike, who was probably bored to tears by now.

Hopping up the stairs, Twilight did her best to continue ignoring the creature, something that was becoming easier and easier as time passed. Pushing open the basement door, Twilight was nearly blinded by the noon sun which seemed to be shining directly into her eyeballs. Wincing, and holding a hand up in front of her face, the girl stumbled down the hall, her eyes slowly adjusting to the light.

“Note to self, get more than one lightsource for the basement. That ever burning candle just doesn't cut it by itself.” Twilight muttered aloud.

With her eyes now no longer in screaming agony, Twilight looked around the empty library. The open sign had yet to be flipped, confusing Twilight, as that was something Spike had always handled himself. Walking into the kitchen, Twilight discovered a note on the table, one written in Spike’s surprisingly elegant claw writing.

The crusaders came by and asked for my help with a project. Figured you were going to be up late so I made you lunch. It's the fridge next to your supper.

Spike.

Twilight sighed, equal amounts irritated as she was relieved. Though not ideal, at least she had had something to eat, though she would have rather liked the dragon to be there in order to take over her todo list. Opening the fridge, Twilight found a tomato, lettuce and cucumber sandwich smothered in mayo, just the way she liked it. Beside it was the vegetarian chili that had been last night’s supper but that didn't catch her eye quite like the sandwich did.

Her stomach rumbled, and she quickly ate the sandwich, following it up with a glass of water, a banana and then the chili. With her hunger satiated, Twilight stopped mid step, only now realizing that she had inhaled all that food in less than a minute.

“Stupid parasite.” Muttered the girl, who had been rather looking forward to actually tasting her lunch.

Grumbling to herself, she made her way towards the front door, flipping over the open sign, and using her magic to lock all the doors to the basement, and second floor. Knowing the honesty of the general Ponyville population, Twilight decided to leave the front door unlocked as she went out. After all, the previous librarian hardly ever showed up, and the townsfolk seemed to have adapted to that rather easily.

Twilight pushed open the front door to the small grocery store near the market, only to pause as a rumbling could be felt emanating from her midsection. Twilight glared down at her belly, as if daring the parasite to do something, only for nothing to happen. Nodding slowly to herself, Twilight hastily grabbed a basket and began to run down her list.

She had been tempted to abandon this part of her todo list as well, but they were out of everything, with even Spike being down to his last emerald. Thankfully there were a sparse few people here at midday, allowing Twilight to shop in peace without having to talk to anyone. Milk, eggs, bread, and the rest of the necessities were added to her cart before Twilight began to wrap things up.

While this was happening Twilight could feel the parasite move and shift, the tentacle in her ass having finally stopped moving after completing its apparent goal. It was almost unnervingly easy to ignore its presence, but difficult to forget about it totally, given its sheer size. In addition, she could also feel the small tendrils inside of her breasts begin to move and shift at about the same time the ones in her pussy began to do the same.

Gritting her teeth, Twilight tried to ignore how strangely good it all felt, keeping her attention focused completely on getting everything done, and quickly. Twilight didn't want to be in public when the parasite began to do whatever it was planning on doing after all. Dropping the last item into her cart, Twilight began to half run, half walk up to the lone counter which was thankfully empty.

Having finally caught a break, Twilight jogged up to the counter, already levitating the first items onto it. The slightly older, graying man behind the register smiled warmly at the girl.

“Someone’s in a hurry. Where's the fire miss Sparkle?” He asked as he began to scan and bag the items.

“Just running some experiments back home is all.” Twilight replied hastily, teleporting her cart away as to avoid the extra thirty seconds it would take to walk it back.

The man merely nodded, well used to the strangeness that always came with living in Ponyville. “Well I won't bother you too much then. Did you need that order of gems you asked for the last time you were here?” He asked.

Twilight wanted to say no, and to leave it until later, but she was already here, and her logical mind refused to allow her to do so. “Yes, but please hurry.” She urged.

The man nodded, turned and cupped his hands around his mouth. “Jolly Green! Get the box marked Spike from the back!” He shouted in a tone so loud it would have made Luna jealous.

Twilight blinked and had just opened her mouth to ask how much she owed when she felt the parasite begin to move once more. Though not quite as violent a movement as last time, the girl was distinctly aware of something traveling up her spine, and towards her breasts. Upon reaching her nipples Twilight could feel some ooze like liquid pour into the interior of her tits, making them begin to grow as they were filled.

Skin stretched as the steady stream of thick, viscous liquid coursed into her small mammary glands. Her body stretched in ways it was never meant to, yet despite this, there was no pain, indeed it felt kind of good. The girl even had to stifle a moan as her breasts increased a full cup size in a matter of seconds, her bra straining to contain all the new growth.

This didn't go unnoticed though, with the near sighted man raising an eyebrow. “Are you okay miss Sparkle? Do you need an antacid?” He asked, reaching for a drawer.

“N-no.” Twilight replied hastily, an arm crossing across her breasts. “It's just… lady problems.”

The man blushed slightly and nodded. “Sorry to hear your having prob… lems.”

Twilight hardly even noticed the shocked expression on the old man’s face as her eyes had rolled into the back of her head. The tendrils inside of her cunt had formed into a single much larger one, which had begun to force open her passage quite brutally. At the same time this was happening her bra snapped, as her breasts continued to grow an entire additional cup size.

With Twilight having begun the day with little more than A cup breasts, to see them balloon to the point that they were already solid C’s was a bit unnerving to the man. Twilight herself meanwhile was barely able to stay standing, her breasts becoming so hot, and tight that she couldn't help but grab them. At the same time this was happening the tentacle inside of her pussy was beginning to travel deeper, stretching her more and more.

“Oh gods above.” Twilight whispered, her sweatshirt becoming tighter by the second.

“I’ll just go check on… that thing.” Muttered the man, who couldn't take his eyes off Twilight.

The girl didn't care though, as the flood of ooze into her breasts hadn't slowed for even a second. In no time at all, her body had adapted to the pressure, her breasts becoming taut as they rapidly grew to contain the ooze. While the man was watching, Twilight’s breasts kept growing, rapidly filling to the point that even Twilight’s hands couldn't contain them.

When finally they stopped they were some of the biggest Twilight had ever seen, topping out at what was likely to be a J cup. Her sweatshirt was by then little more than a belly shirt, the cloth having managed to somehow stretch without breaking unlike her undershirt and bra. Twilight couldn't help but marvel at just how heavy her new breasts were, the pendulous orbs physically weighing her down. Yet they didn't sag very much, her back having suddenly become much stronger than it had been a minute ago.

“Shouldn't you be doing something?” Twilight asked, pointing to the item the man was still holding an inch away from the scanner.

“I err… yeah.” Muttered the male, who scanned the last item before turning to his equally stunned assistant, who had a box of gems in his hands.

Scanning the box, and putting it aside, the older man managed to tear his gaze from Twilight’s heaving bosoms long enough to check the total. “That's forty nine bits.” He all but whispered.

Twilight nodded, reaching for the rather stealthy pocket on her dress, and retrieving a small wallet, only to immediately drop it when the tentacle inside her vagina moved again. It had paused midway through the transformation of her breasts, remaining stationary until this very moment. Its size was significant, easily having become the thickest thing ever to be inside the poor girl, who was now grasping weakly at her fallen wallet.

“Miss? Are you alright?” Asked the man nervously.

“Just f-fine.” Twilight replied through grit teeth, her fingers clasping around her wallet only for her body to seize up immediately.

The tentacle had hit the entrance to her womb, yet the sensation wasn't as unpleasant as Twilight would have anticipated. Anything hitting that deep was supposed to be painful, yet this felt incredible, like she was having the best sex of her life. So good was the tentacle that she couldn't resist moaning loudly, and quite lewdly, the two male’s eyes getting bigger by the second.

“Uh miss Sparkle, would you like me to grab your wallet for you?” Asked the younger man who stood next to his elder.

“N-no. Its fine.” Twilight muttered, distinctly aware of the tentacle pulsing and twitching, as something flowed into her body.

Shutting that thought out of her mind, Twilight focused on simply getting out of this situation with her dignity more or less intact, a goal that was becoming more out of reach by the second. Grunting, Twilight grabbed the edge of the counter in one hand, and her wallet in the other before heaving herself into a standing position. The unicorn was distinctly aware of a sloshing sensation coming from her midsection, and the strange sensation of liquid being pumped inside of her was still present but she continued to ignore those things.

“There.” She stated, slamming the bits on the counter. “Fifty bits.”

“Uh, ma’am?” Asked the second man while pointing to her midsection.

Twilight lifted an eyebrow and looked down to her now bulging belly which had almost completely popped out of her sweatshirt and was visible past her now monster tits. “Well that explains the draft.” Twilight muttered to herself.

“I know I sound like a broken record but are you sure your okay?” Asked the first man.

“Just fine.” Twilight replied through grit teeth. “Now if that is everything I- not again.”

The sorcererous had about two seconds to grab the counter before a sizable orb of liquid was pushed inside of her womb. The sheer size of it meant it was difficult to even get through her cunt as it was just that big, something it did only barely, and only after it had stretched her far beyond what she had considered possible. The sound of the orb joining the veritable sea of liquid already inside of her womb made the girl blush even harder, her stomach now large enough to make her appear pregnant and ready to burst.

Worse yet, she was seconds from orgasming, the feeling coming so hard and fast that she couldn't hope to hold it at bay. It was strange to feel it come out of nowhere like that, but then again her entire body felt strange. With feelings, and sensations she had never felt before flowing through her constantly and seemingly without end.

It was enough to make the girl begin to wonder what else the parasite had changed about her. Obviously it had modified her womb, and the rest of her reproductive organs in some manner, but the exact nature of said change was lost on Twilight right now. Her magic sparked, but she couldn't concentrate enough to make the spell actually work, and it fizzled just as her knees gave out.

The weakness that had been plaguing her all day returned with a vengeance, and she fell to the floor, one hand clutching the edge of the counter while the other grabbed her bloated belly. The warm, thick liquid which filled her insides shook as she trembled, a strangled moan escaping her lips. The massively thick, and all consuming tentacle which filled every inch of her pussy twisted and writhed, as if trying to make sure she came as hard as possible.

The enormous invader seemed to know every inch of the inside of her body, and its every movement hit another pleasure center, sending a lightning bolt shooting through her body. The girl moaned, and babbled nonsense, as her eyes threatened to roll into the back of her head. The best orgasm of her entire life was currently coursing through her body and she was being watched by two shocked men as some parasite violated the deepest reaches of her womanhood.

It was not an ideal situation to say the least.

One thing it did give her though was a boost of magic gained by the powerful release of pleasure, aiding her spell casting and somehow allowing her to complete the teleportation spell which had failed a minute earlier. With one final cry of pleasure, Twilight grabbed her groceries before vanishing in a flash of magenta lights, causing both males to look away. When they looked back Twilight was gone, two sweaty spots on the ground being the only evidence she had even there in the first place.

“Woah.” Muttered the younger male.

His elder nodded. “I think I’m going to take a quick break and run home to the missus.”

“And I’m going to use the washroom, for… reasons.” The younger added.

“Just make sure you tell Clyde to take over.” Replied the older male, who had already torn off his uniform and was walking to the door.

“Right.” Muttered the other male, who all but sprinted into the back of the building.

“There's gotta be a way to get rid of you.” Twilight muttered bitterly as she crawled weakly over to the table, her magic already reaching for her quill and ink.

A gurgle from her stomach made her stop and look down to where her stomach had grown to the point that it made her appear nine months pregnant with at least twins. The enormous change in size made Twilight’s body twitch, and a sudden tremble to run down her spine. She couldn't help but feel less and less repulsed as time went on, the sight of her slime filled stomach making her pussy begin to ache.

The need to be filled, to be made larger was nearly all consuming at this point, and she could feel her nipples begin to leak a gelatinous substance. The fact that the parasite had retreated from her breasts, leaving her now utterly massive tits alone was both pleasant, and uncomfortable. In the short time that the parasite had penetrated her nipples, Twilight had grown strangely used to the sensation, even becoming aroused by the mere thought of it happening again.

Groaning, Twilight hastily scrawled another letter, hoping her librarian connection had found something to assist her since the last time they had exchanged communications.

The changes were coming in slower now, either that or they were far less notable, the parasite having apparently stopped now that she had an enormous rack, and a womb full of slime as well as god knows what else. At least it hadn't hurt, Twilight thought to herself, though that was far from a comforting thought considering just how much her body had been altered over the last hour.

Summoning her magic, Twilight was ready to send the letter away only for the door to the library to be thrown open unexpectedly. Grumbling to herself, Twilight struggled into a stand, looking over the back of the couch and towards whomever had interrupted her train of thought once again.

“Zecora? Oh thank the stars it's you.” Twilight muttered, her legs only just barely able to keep her vertical.

Upon seeing the girl’s current form, Zecora’s eyes became wider still. “Did you not take my urgent advice? I told you of the hefty price!”

Twilight winced. “I used enough power to restrain an elder red dragon. I assumed that was enough, and was subsequently proven wrong.”

“That much I can plainly see how far along are thee?” Zecora asked, the zebra walking over to the other girl and giving her an appraising look over.

“Well my tits are huge and leaking what feels like jello, and my belly is so heavy I can hardly walk.” Twilight replied, lifting her shirt up and revealing the thick green substance dripping from her nipples.

“Then it is as I feared. To you this must be very weird.” Zecora remarked, while shaking her head.

“Your telling me.” Twilight grumpily muttered back, dropping her sweater which was now little more than a belly shirt. “Is there anyway to remove it or change me back?”

“At this point there is little you can actually do. You and it are stuck fast like some sort of glue.” Zecora answered, with a shrug.

“So I’m stuck like this forever?” Twilight asked, grabbing the zebra by the shoulders. “Because I don't have the hips for this Zecora. This rack is bad enough, but I can't support it and this belly at the same time.”

“Your stomach will eventually go down, but there is no reason to frown.” Zecora began, a blush crossing her face. “You grow more beautiful by the second, even if you are increasingly more fecund.”

Twilight opened her mouth to say something only to frown. “Well, I suppose it could be worse, but my back won't be able to support this weight.” She blushed and looked down. “Do you really think I still look pretty?”

“Of that, you can be assured, and though much changes you have endured. I know it will become more manageable soon, and perhaps even become a boone.” Zecora replied with a small smile.

“Well I was always a little jealous of Rarity and Fluttershy…” Twilight muttered, a hand going to her enormous breasts, and idly noting that already they were feeling lighter, her belly a little smaller.

Whatever changes that were continuing were evidently reinforcing her back, making it easier to bear the weight and helping to ensure she was not overly weighed down by her new breasts. From the way Zecora spoke of the creature, it wouldn't hurt her, or cause any permanent injury, but that was something that needed to get cleared up, and soon.

“So, this thing won't kill me or something?” Twilight asked nervously. “How do you know about it?”

Zecora shook her head. “This creature is native to my home, and I found more information in this tome.” The zebra pulled a thick leather bound book from the bag at her hip. “It is called the lover’s plant, and hurt you is something it can't.”

Twilight reached for the tome, struggling to work her arms while her tits found a way to constantly get in the way. Flicking through a few pages which Zecora had carefully earmarked, Twilight quickly came to the conclusion that the creature was indeed harmless, for the most part. Though permanently bound to it, the creature merely consumed her waste, and in return made her incredibly fertile, and able to bear many offspring, as well as feed them.

The book went onto state that after a while it would even sink into her body, becoming nearly invisible save for a bump along her back. Though unnerving, it would at least mean the creature was out of sight, and wouldn't get in the way. Sharing a body with the parasite was not an end Twilight would have anticipated actually enjoying, and yet here she was.

With a resounding sigh, Twilight placed the book on the coffee table, and all but collapsed into the couch. “Well that's a relief, I guess.”

Zecora nodded eagerly and sat next to the girl, making sure to keep her hands over her crotch. “Something has stirred something inside me. This evening, are you free?”

Twilight blinked, only now noticing the large bulge Zecora was only barely able to hide. All at once Twilight realized just how incredibly curvy her body had become over the last hour. Not only were her breasts huge, but her figure was rounding out quite a bit, her butt becoming large enough to make even Celestia jealous. A quick calculation told her that she would only become more curvy as she continued to absorb the thick slime in her womb.

And though she had never considered such a possibility, Twilight couldn't help but imagine dating the attractive zebra. With a resounding sigh, Twilight shook her head and chuckled aloud to herself. “When it rains it pours.” She muttered, before smiling, turning and kissing the zebra hard on the lips.

Change, she figured, was pretty good.
