Tap! Tap! Tap!

Waiting for an Amazon delivery was always a test of patience. In the dining room of the spacious two-story house a lone vaporeon woman barely into her twenties sat staring at the clock. The only movement breaking her near catatonic state was the rapid twitching of one blue finger striking the varnished wood with its manicured black claw.

She remained in this state for over five more minutes before an eevee woman entered from the foyer. They walked right past the vaporeon only mindful of their thick tail and fluke obscuring the route to their family fridge. It wasn’t until they poured a glass of orange juice and returned the carton that they turned to eye their younger sister with mild interest.

“Fynn? Have you been waiting here all day?”

The vaporeon’s finger curled back so she could slam the table with her whole fist instead. “What the hecking good is a Prime membership if rush delivery still ends up late!? This is so ridiculous.”

“Yup, this sure is,” Trinity said with a disinterested eyeroll. She paused to drink her fruit beverage before going on. “You only ordered that thing two hours ago. Maybe you should go back to your science stuff to pass the time?”

“That’s pointless and you know it! I can’t complete the experiment without it.” Fynn nodded with knowledgeable confidence without ever diverting her eyes from the wall clock. As though everyone already knew all about her frustrations.

Actually, there was very little Fynn’s family understood when it came to her passion for science and research. They were an exceptional family of eeveelutions, possessing both extreme powers and sexual characteristics, even by anthro Pokémon standards. For example, both girls wore T-shirts in the double XL range, yet still stretched them out around the chest enough to have the hem raised above their midriff.

This was almost certainly the result of genes passed down the family line. Since practically any Pokémon can mate with another, they could be part Mewtwo for all Fynn knew. And that was something she really wanted to find out, preferably today.

“Just… remember to stretch or something, okay?” Trinity hid her sarcastic expression behind another gulp of juice. Her sister let them leave with barely a snort of steam from her petite black nose in parting.

Unfortunately, Fynn let her concentration waver too long. Now she couldn’t stop thinking about how sore her butt was after resting on a stool for an hour. These cheap things were way too small for almost everyone’s wide backsides. It was a wonder mom still hasn’t changed them for bigger cushions yet.

With a quick pop of her stiff neck, Fynn stepped onto webbed paws taking time to stretch out her arms and tail. Now she was annoyed at having to take her sister's advice and find something to do.

A light snipping of sheers from the backyard drew her attention to the windows. It was hardly a surprise to see a leafeon around Fynn’s age tending dutifully to an arrangement of flower beds and berry bushes outside. Summer was Amber’s favorite season and she wasn’t missing a day to get the most out of the family garden. The fact she always did these chores naked was about the only odd thing. And also, why the backyard had high walls.

Fynn shrugged to herself, finding no other options ready. Maybe she could offer some help in calculating the perfect fertilizer compound or the proper distribution of water.

DING DONG!

Or her package could finally arrive. Fynn froze mid-step with ear fins raised. A second later she was halfway across the house flinging its front door open with overflowing delight. The startled delivery badger halfway back to their truck didn’t have time to finish wishing the vaporeon a good day before the door was slammed closed again.

Fynn’s fishy tail fluke slapped rapidly against the carpet all the way back to her laboratory. Both blue arms hugged the freshly acquired brown box tight between her bouncing breasts like the world's greatest treasure. Once inside her privately sterilized work space, she made quick work on cutting it open and tearing aside lots of airbag wrap.

The useless redundancy of such packaging always amused her. Inside the paper box the size of a tool box was a smaller box composed of solid steel with magnet locks. When Fynn used the provided keys to get those open, there was a containment tube covered in stickers warning about chemical hazards and handling instructions.

Of course, she wasn’t excited enough to rip that straight open. Fynn took the time to squeeze inside a special biohazard suit made for her thick curves and tail before taking it into her ‘clean cube.’ A simple plastic bubble with heavily filtered air flow and sealed entrances. It was a bit makeshift but still both a functioning containment and one of her favorite places to sleep during long work hours.

Last time Fynn unleashed unstable chemicals through the house almost everyone grew a second head and third boob between their already giant mounds. Mom did not care for that at all. Now fairly certain that wouldn’t happen again, she carefully took the canister by one arm and opened its lid.

Getting a sharp hiss of released air pressure was a good sign, but it was seeing the three vials still intact that allowed Fynn to relax. Her steady hand extracted them one at a time onto an examining table before discarding the canister entirely. Each tiny glass tube contained the same brown liquid, showing nothing extraordinary worth the vaporeon’s giddy attention.

That was understandable to Fynn, since few actually knew what raw essence looked like. She had a working theory that all Pokémon powers derived themselves from the same generic source, a pool of magic, if you wanted to get supernatural. At this point in evolution with literally hundreds of various species now known, finding even this small amount of blank power was rare and expensive. Her experiment today hinged on exposing her blood to it and trying to split it off into all the different other species her ancestors might have cross bred with.

The whole family was probably going to give her flack for the small fortune spent to get it. A totally acceptable risk if mixing it with the genetic code of her and her sisters helped determine how deep their family history went.

Speaking of which! Fynn shook her head so fast that her neck ring of fins fluttered, a bubbly laugh escaping her slender muzzle. Once again, she’d gotten so caught up in the excitement of this experiment's possibilities that her internal exposition overworked itself. 

Not that she could calm down now that there were prime reagents secured for use. Getting back out of the containment bubble and hazard suit were a grinding torture on the vaporeon’s patience. Before long she was running dangerously across the lab to a workstation already set for a first run of blood trials.

Even with eight relatives, convincing one to agree to a needle was hard. That’s why she’d already drawn plenty of her own DNA for this. Hopefully if there are some astounding findings in their ancestry the others would be interested enough to play ball. Having a variety of subjects might even discover different lineages. It wasn’t like Fynn would cause a disaster with a few drops.

“Hey, Fynn!”

“AAH!”

The jolteon girl, on the other hand, very nearly caused several disasters by speaking only inches away from Fynn’s ear flap. Her warm smile immediately explained the epic jump scare had been intentional. At least for a small prank. She hadn’t planned for the vaporeon to slam her thick backside into the lab table, toss the vials they were holding into the air so she could catch equipment from falling over, and then twirl in time to grab the vials on their way down.

“Damn, girl! You’re a lot more dexterous than you give yourself credit.”

“No. Damn you, Sparky!” Fynn huffed, face beat red. She very gently placed her prized samples on the table before addressing the jolteon fully. “The hell are you doing sneaking up on me during an experiment?”

Sparky gave a casual shrug that squeezed her tank top over the enormous boobs filling it taut. One arm promptly outstretched toward Fynn in offering of the Starbucks cup it was holding. “I was getting you coffee like you asked this morning. Because you didn’t want to miss your delivery or something.”

“Oh, right, um, thanks!” Fynn’s anger dispersed in a rush of embarrassment.  Staring at the clock for hours on end had somehow made her forget asking her sister for refreshment while out on their own errands. She took the offered cup, forcing a weak smile. “Did you get the…”

“Extra creamers. Yeah.” Sparky dug into the back pocket of her cargo pants, producing a handful of little plastic containers. These she happily deposited into Fynn’s free hand, which were also placed on the lab table. “Didn’t realize you were so engrossed in another mad science thing. You make the most adorable squeak when you’re surprised.”

“Nyeeh!” Fynn jutted out her tongue in a grumpy raspberry that only made Sparky laugh some more. “You almost ruined a fortune in samples, you know? This could be a breakthrough in our…”

“Family history as we know it.” Sparky finished the sentence before drinking from her own coffee cup. It helped hide her amused grin when Fynn turned to glare. “I mean, I wouldn't be surprised if you were part rattata, but… Yeek!”

“Out! Out!” Fynn squeaked, barraging her sister with the beanie babies she kept on every table for decoration. Despite causing no damage the jolteon backed away a few feet before marching out the door, a soft elephant bouncing off the back of her head on the way.

“Oi. Sisters.” Even with that little prankster out of the lab, Fynn still felt agitated from her near miss. She stared straight at the lab equipment while ripping off the creamer packages one by one and pouring them into her drink.

At least Sparky got the drink home still hot and with the chocolate powdering she liked. She only stirred it twice before chugging the entire cup, savoring each huge gulp sliding down her slender throat. Having the ability to breathe underwater had its perks. Within ten seconds she pulled the empty container away with a satisfied hiccup, taking a napkin from a stack on the table to wipe the run off from her chin. That was just what she needed to get back in a better mood. Now she had a warm fire in her gut and the focus of caffeine for the task at hand. Time to take these vials and…

“Uh…  oh…?” Fynn started at the unopened coffee creamer pod in her hand. A glance at the table found the right vials, only with their corks popped off and no fluid to speak of inside. Her eyes looked from them, to her coffee cup, to the creamer, and repeated the actions several times. Unfortunately, no matter how many times she did the math in her head it couldn’t come to any other conclusion. “Well, at least the essence was tasty. Uh… UUURRRPP!”

The cup and pod slipped from Fynn’s hands while grabbing her muzzle and stomach at the same time. Before she could even blush at the involuntary gas expulsion a fluttering sensation caused her stomach to bubble against her palm. The vaporeon’s eyes grew their widest as the fire inside spread into an inferno. Exposed parts of her smooth blue skin became glossy with dense perspiration, making her muzzle hang open in dog-like panting.

“Oh no! This… Nngh… Isn’t how I wanted to experiment,” Fynn groaned between little twitches across her body. She grasped onto the lab table in an effort to keep steady against the assault. There was no doubt that much essence ingested at once would spread quickly into her bloodstream and then… well, the intended result had been to divide her cells among its potentially many different lineages. Her fishy tail rapidly slapped its fluke against the wooden floor at the prospect.

Heat shot from Fynn’s stomach up into her chest, filling the large mounds with unbearable levels of tension. Hands balled into fists against the table as she grit her teeth trying to bear through it. Lord only knows what she’d do if she started exploding into several different species of herself.

BWOOMP!

“Um…”

Well, that was certainly not the explosion Fynn’s calculations predicted. In the span of seconds, her already huge breasts gave a hard shift and surged several inches further from her chest. Gravity shifted the rush of additional mass with a hard bounce that created several tears in a shirt that no longer held any slack. She tried reflexively to pull the hem down with no luck. Over half the sloshing mounds were falling out with part of their deep aqua areolas exposed.

“Nnggh!” The new weight quickly imposed itself on the little vaporeon. She gripped at the table with ample fat squishing between her biceps. The lowest part of her breasts even settled on the metal table with their increased hang, sending a cold shiver through her spine. “O-okay. I guess t-this could have gone a lot wor-EEERRRRGGH!”

CRRRRRRKKKLE!

Heat roared up inside the vaporeon’s center once more, plummeting into her pelvis in a waterfall. Fynn arched her back letting loose a cry of mixed surprise arousal. Tension struck her right side, causing her to bump in time. With a loud crack the adjoining hip stretched out nearly a foot wider. Before she could process this the internal force rebounded into her left side, causing another hard bump and expansion. The button and zipper of her pants broke under the formation of an exaggerated hourglass figure.

FWUB! FWUB! FWUB!

“Mmmpppphhhhh!” Fynn bit her lower lip trying to stifle another moan. This shouldn’t be happening by any accounts, let alone feel this good. A second wave of energy plummeted from her gut into her lower half, causing her butt to billow in small surges. Seams creaked and popped until finally failing their containment, letting a bright blue shelf ooze over the waistband. Their gaining weight quickly pushed it down until the vaporeon’s whole crack was exposed under a flailing fish tail.

Scientific standards dictated the young vaporeon should have been documenting these spontaneous cases of rapid growth. Yet all she could focus on at that moment was how soft her glutes pressed between exploring fingers. Attempts to pull her pants back up met with similar success as her shirt, essentially sending her backside jiggling in a manner that could be mistaken for twerking.

“Ugh! So glad Sparky left. I don’t need ‘bubble butt’ jokes right now.”

A few more tugs on the waistband finally convinced Fynn of her clothes decreasing practical functions. More rumbling from inside her gut alerted the vaporeon that whatever the essence was doing to her was still not over either. Twirling on one heel she set her sights on the emergency medicine cabinet stocked with stabilizing compounds…

“WHOOP!”

TWHOOMP!

...and fell flat on her bloated ass after already forgetting the major increase in her body mass would affect her center of balance. The world spun in different directions thanks to her eyes rotating out of sync. By the time she shook them back into alignment it was already too late. The power fusing with her blood built to its strongest blaze yet, releasing a pulse through her body down to its webbed toes and fingertips.

“HIC!” A wave of dizziness almost knocked Fynn over. Her vision blurred but could still make out the lab shifting in perspective like she was rising above it all. Everything suddenly looked below her eye level in spite of remaining sitting on the floor. It didn’t escape notice that even her heels dragged along the floor with increasing reach for the far wall. “Oh no…”

The vaporeon rolled onto her shaking legs immediately confirming she’d spontaneously grown bigger. Most of the tables had gone from reaching her waist down to her knees. Both shirt and pants clung in tatters around her expanding body, all but destroyed by her increased proportions.

“O-okay, Fynn. Calm down.” The vaporeon brought her hands in front of her, raising and lowering them with the inhale and exhale of air puffing out her chest. A simple breathing exercise that helped her think through many wayward experiments. “I need to try the suppressors. It’s doubtful a simple anti-growth pill can cure this but it might buy me time to-HIC!-mother fu-arrgh!”

There wasn’t any warning build up this time. Fynn had a second to register the heat rushing through her body and was overcome with a sensation of air rushing around her, like in a rapid fall.

BONK!

Except her head shot into the ceiling with a very painful rush of growth. Fynn hunched over cradling her cranium amidst a tirade of cursing. The impact shattered several lights and left a deep imprint on the plaster. Thank the legendary gods she hadn’t been standing under a support beam. Still, having gained another three feet of height didn’t help ease emotional tensions.

“HIC!”

SHRRRRTTT!

Hands clasped atop giant sloshing breasts unable to do anything but hang on. Another hard surge sent her tail slinking through the lab overturning tables with its muscular girth. She could feel the fabric of her clothes vibrate for a few seconds only to completely explode off her body’s curves. Everything from boobs to thighs were packing on additional pounds of muscle and fat, with a soft cracking possibly being the addition of bone width to her hips.

THUNK!

“...god damn it.” Fynn’s dejected sigh sent papers on the table below her fluttering thanks to an increased lung power. Even when hunched over her upper back pressed into the ceiling causing more costly damages while she worked her thickened legs into an awkward squat. Looking around the lab led to estimating her height surpassing twelve feet tall. Gods only know how much additional weight her jiggling blue body had gained. “Hic? Oh, no no no!!”

At this rate she was going to demolish the anti-growth countermeasures with the rest of her lab. The feeling of being stretched began overtaking Fynn’s body, especially around her arms, legs, and tail, but she ignored those in a mad dash for the door. Her whole spine was put to the test with having to hunch forward as far as it’d curve. Having two huge udders dangling off her chest didn’t help with balance much. As long as she wasn’t smashing into the ceiling with this next growth spurt everything else could be addressed later.

Ignoring further crashes caused by her expanded fluke thrashing through the lab, Fynn hobbled fast as she could for the doors.

THWOOMP!

It was already a tight squeeze no matter how hard she tried to bunch up her limbs. Breasts poured through the door frame only to get stuck squeezed against each other halfway through.

“Frick! Frick! Frick!” Fynn rocked back and forth pushing with all the strength her thunder thighs could manage. The wooden door frame snapped in several places while the walls developed spider-like cracks, but her bust refused to flow through.

Realizing time was a dangerous factor, the vaporeon wedged her fingers around the blue mounds, managing to get a grip on either side of the stubborn portal. Now she could at least pull and push her fat body at the same time. Sounds of increased structural damage tickled at her ears, although that could have been the plaster raining from above. Slowly but surely, she felt her fatty blue skin sliding around the tight archway before finally popping out. At which point her lab’s entrance had been widened by a good three feet.

WHOOMP!

“Oh, you gotta be…”

POP!

“...never mind.” Fynn gave a dejected sigh, unable to complain how unintentionally renovating a doorway made it significantly easy to wiggle her bloated rear through it. Anything that worked in her favor at this point was a blessing.

“That’s some rowdy experiment you got going on, Fynn!” Sparky’s voice tickled the younger eeveelutions ears before they came around the corner. “I can’t finish this ham sandwich I got. You want a sna-ah!! What the heck happened to you!?”

Fynn gave an impish squeak as she stood the best she could hunched over, arms hugging her plush chest like she was trying to hold giant water balloons. Before her muzzle could open with the start of an explanation an even lower squeak cut her off, curves jiggling from another tense heat. “It’s still happening! Gang way!”

Even though being a jolteon gave Sparky the reflexes to duck, she still found herself blindsided by her sister's expanded hip sway as they stampeded past. She slammed into the hallway wall getting the wind knocked out of her with only a sea of blue skin wiggling in her vision. This was Fynn’s fishy tail, of course. A thought that registered to Sparky right before the trailing fluke slapped her across the front and sent her falling face first to the floor.

Fynn couldn’t afford to care about accidental assault right now. With each passing second the walls closed in on her naked body. It was actually an intriguing sensation feeling the world was shrinking when she was supposed to be growing. That might be worth studying later, but not destroying the family home took priority.

Shame there were still going to be some casualties. The back door was just a long sliding glass pane, so it stood no chance when Fynn body-checked into it. If the family hadn’t been alerted that something was up by now, the loud shattering of glass and small tremor of her ass hitting the grassy backyard definitely got everyone's attention. Good thing Amber had apparently finished her garden duties, or she might have experienced some unexpected vaporeon curves like Sparky.

“Aaah gah!” Fynn was starting to get angry that the rare liquified manifestation of raw power wouldn’t let her catch a breath. Another warm blaze sliding through her being sent the vaporeon rolling back onto her feet sending broken glass sliding off her slick curves. Nice to see being nearly tall enough to see over the two floored house meant she just barely avoided a calamity, so far.

Within the span of three confused blinks, Fynn suddenly found she could easily see over the house without even stretching. Giving off more panicked squeaks, she turned and jumped over the fence that barely reached her knees now. An effort that felt pointless when her tail fell upon the section, cracking it in two before the dragging fluke ripped it clean off.

“Holy butts!” Fynn stopped a few wide strides away from their backyard. She had been initially flustered about causing more damage, only to be drawn to the thick wiggling log her tail had grown into. Even at normal size it’d never reached this far behind. The fluke looked to have a span that could send cars flying if she put her equally enormous hips into it. “Argh! Analyze later. I need to get away, find somewhere safe to grow until this stops. Crap. Is this even going to stop!”

The answer so far seemed to be a resounding ‘no.’ Well, technically, it was the echoing boom of her bare feet. Whatever force was currently imposing the vaporeon’s rapid expansion had grown beyond random surges and was now raising her vantage point in a steady incline towards the sky. What a strange sensation watching everything shrink away like the zoom on a computer image. Even if she stood still her heels dug into the soft earth or hard sidewalks while her stance naturally stretched wider in proportion to her size.

Not that standing still was currently a good idea. The view of her world getting bigger became mesmerizing, like everything else was changing instead of her plump behind. That didn’t mean she wasn’t still affecting it when her feet dug so deep into the earth, they became stuck. Fynn’s squeak could be heard across neighboring counties thanks to the increased zeppelin size of her lungs, although it didn't help the unaware Amber or Trinity brace for the seismic shake that occurred when her ass hit the street.

“Ooowwwww…” Fynn whined, rubbing her backside with both hands. Good gods. All that magic really did pack on the fat back there, and yet it did nothing to cushion her fall. Pain wasn’t doing her already flustered anxiety any favors either. Through her dizzy vision she could see her legs stretching towards the houses across one side of the pavement while her tail was already curling across two or three front yards of the opposite. “Ooohhhh!! It just keeps getting faster. Mom’s going to ground me as is, if I destroy too much of the house. I might end up buried if we take out the neighborhood with it. Think, Fynn, think!”

She needed to get out of here. But where could she go? A growl of frustration rumbled through the suburbs as she tugged her frilled fishy collar in frustration. Fire built within her again with all focused on just wishing to me thousands of miles away where she could at least grow without hurting away.

POOF!

And just like that Fynn was…

Uh…

“Where the hell did I go?!”

One second the vaporeon was counting down the seconds until her webbed feet crashed through the front door of unsuspecting neighbors. Without so much as a blink everything vanished into a black void. Fynn tried to stand only to yip at the realization there was no ground under her. She was a water Pokémon simply floating around, stuck in an awkward tumble by her motions.

At least it helped bring something bright and colorful into view. Instead of a black space, now all she could see was a blurry mesh of browns, greens and a heck of a lot of blue. Occasionally blotches of white shifted over everything like they were on a separate layer.

“Oh! No WAY!”

Fynn whipped her gaze to the right, seeing the bright blue stretch off into a distance curve bordering with the black void. A glance to the right saw more of the brownish mass go into blue and off into a distant curve. It was exactly like looking at the surface of a really huge ball.

Or a planet.

“I’m in space!” Fynn cheered, not knowing or caring how she could even speak in a vacuum. The vaporeon laughed and thrashed her tail in excitement. Her thick rudder appendage’s motion sent her swimming through zero gravity in a reckless spiral. Yet her mind was orbiting even faster. This was a fantasy any scientific mind could dream off. She was orbiting around the earth.

An earth that was gradually diminishing in size. Seriously, with only the planet as a reference Fynn’s seemingly endless growth somehow lost its urgency. Now that she was safely free floating in the emptiness of the solar system there was no need to worry about hurting anyone below. More and More Earth was starting to look like a novelty toy ball compared to her looming mass. Hell, it took a lot to resist swatting the moon every time it orbited past. Almost ten minutes of uninterrupted giggly relief passed before another thought struck the vaporeon.

“Did I teleport myself up here!?” she blurted out loud at the beach ball planet shadowed by her equally large breasts. Although it was unlikely anyone across the many continents understood the rumbling vibration noises breaking through the stratosphere. “How did I teleport? Can vaporeon’s learn to teleport?”

All kinds of calculations raced through Fynn’s mind while she continued watching the world spin. The damn thing was looking like a basketball ready to be dunked on, if only she had the gravity to bounce something besides her butt. This experiment was going off in some incredibly unexpected ways. Instead of separating her genetic code into its many different ancestral traces over the generations, could it all that mana be augmenting herself with them instead. That might explain her body’s rapid size increase as a means of storing so many different kinds of power, and fat, it would seem. Her eyes grew wider than the annoying moon that tried to imitate a stray softball narrowly missing a collision with her head. Just how many different types of Pokémon were getting created and integrated from her DNA would be beyond estimation. She could end up the embodiment of dozens, maybe over a hundred species combined.

“Wait until I brag to Trinity about this,” Fynn gloated with a giggle, only to gasp. Her gaze dropped back down to the general brown blotch she hoped the family house still rested. “Crap! I hope everyone is still okay down there.”

Sure, there might have been some collateral damages to the property but aside from Sparky’s sandwich she was…pretty sure everyone is still fine. Worry crept into her tail making it wag violently enough she began orbiting around the basketball-sized earth parallel to its moon. The warmth of volcanic energy was bubbling inside her guts again, going unnoticed from the stress. How she really wished with every fiber for some way to at least check on everyone.

“Ah!” Fynn jumped when her vision suddenly became bright and colorful again. Gravity had asserted control once more, keeping her plush butt overflowing on a kitchen stool once more. “The hell?”

A quick glance around confirmed she was back in the kitchen, even the same seat she had been waiting for her samples since morning. Although there was a nice wreck of shattered glass where the back sliding door used to be. Her blue face turned slightly violet over how her giant derriere had bent the frame into a wide outward curve. Amazing that she could just pop from being the size of a planet and back with just a thought.

No. Wait. That didn’t feel exactly right. The vaporeon looked down at her hands resting upon the kitchen counter, drumming claws against the wood. She could certainly control herself without limits. However, her senses felt distant, dulled a little. Looking around once more Fynn could see her vision also got blurry around the edges like she was wearing something over them. When she focused harder on herself, she could still feel the cool weightless freedom of space and a warm sunny afternoon at the same time. Was this some kind of remote doll?

“So, this is what an advanced VR game might feel like,” the tiny embodiment of Fynn proclaimed with a giggle. While not exactly a return to her normal state, the vaporeon wasn’t about to argue with the ability to create fully functional automatons for interacting with a tinier world. A world that only continued to shrink away while her aquatic blue curves filled out the solar system. She couldn’t even begin to theorize what combination of Pokémon abilities were allowing her to do this. Their family might even have some Mew in their genetic history, or possibly some undiscovered god level species!

“There you are. You agent of chaos!” A familiar voice barked from the foyer. Sparky was making her way towards the enthralled Vaporeon digging bits of ham out of their cleavage. They were probably too agitated to notice the bread slice stuck to their hair. "The hell are you doing going all giant in the house and sitting back down? Mom's going to kill you when she sees what your bubble butt did to the doors."

Fynn rubbed at her gill collar forcing a cherry smile. "Heh! Yeah. Sorry about the tail slap. I can totally fix this before mom gets home."

The response had been a typical instinct when one is facing parental punishment, but then it made Fynn start to think.

Sparky scoffed at the weak offering only to watch Fynn begin waving their hands around like some bombastic wizard. "How you planning to renovate three butt grooves out of the wall? Got a magic trick up your-HOLY HELL!?"

"For lack of a better term? I guess I do." Both rows of sharp teeth poked out with Fynn's grin. With each wave of her slender little paw fingers, wood cracked and supports snapped. Paint began reapplying itself along reforming walls until the doorframes looked better than the day they were built.

She glanced briefly to enjoy the hanging jawed expression from the jolteon, deciding to show off with a snap that sent out a small shower of sparks. A cascade of jostling noises filled the room as they watched sparkling mist rise up from the floor. Another snap directed it to converge along the inner doorway and Sparky realized it was the pieces of glass crushed by her vaporeon relative just minutes ago. Shards connected exactly back in line with the smallest particles until their sliding back door glinted fresh and clean in the sunlight.

“Okay. That was impressive.” Sparky nodded her approval, giving Fynn a playful hip bmp on the way over to their fridge. “So, your whole experiment thing was a success?”

“Kinda, sorta?” Fynn shrugged sheepishly across space along with her miniature avatar. Remote controlling a homunculus might take some getting used too. “I accidently drank all my samples at once and now I think I’m mutating with the genetic code of every species our lineage has ever bred with.”

Sparky nodded along while pulling out a chilled bottle of hard lemonade. Odds were good she wouldn’t understand the full scope of Fynn’s words without a few diagrams and maybe a satellite feed of the vaporeon taking up a significant portion of the milky way by now. “Neat! How’s that going?”

“Well, I’m so huge I’m pretty sure solar systems are revolving around my ass, and it’s possible that’s my hair instead of the sky out there.”

A pause while the jolteon glanced out the freshly restored glass door and back to Fynn. With a long chug of her drink, she waved at Fynn’s body with a free hand.

“And this is? What? An illusion?”

“I seem to have created an exact replica of my original self using a combination of abilities way beyond our eevee genes. It’s going to take a lot of study and tests for me to even begin figuring out exactly what species we’ve crossed with over the centuries. We might even make history for being descendants of new discoveries.”

BURP!

The involuntary reflex from Sparky wasn’t meant to imply sarcasm or disinterest. On the contrary she always enjoyed seeing her niece get passionate about something so creatively fueled, no matter how hard it sometimes got to follow. It was just that her citrus beer was extra carbonated today.

Besides, ‘the solar system is revolving around my butt’ is only the third strangest declaration the vaporeon had ever made during an experiment.

So far…

“Well, you’ve certainly learned to repair property damages. What other kinds of tests do you have in mind?”

Fynn’s fluke rapidly slapped the tiled floor. A strange smile crossed her muzzle. “I was hoping, since some of you are home today, we can do some family trials.”

The next swig of hard lemonade went up Sparky’s nose with her panicked sputter. “I have a date tonight. Don’t you freakin dare!”

A webbed hand was already making exaggerated gestures at the jolteon. Energy struck into Sparky’s stomach, making her gasp like she’d been sucker punched. Warmth rushed through the rest of her body making muscle seize up and let the bottle slip from her hand. She would have remained paralyzed by the sensation for a long time, if her senses weren’t jump started by a hard shifting in her groin.

“Oooh fuck!” she gasped again. This time her voice carried the weighty inflection of arousal to match the blush on her golden furred face. Legs quivered as her pelvis pulsed and pushed against her body, developing tension with her pants. Her eyes shot open wide watching the denim crotch stretch and distort into a sizable bulge. After a few deep breaths to let her mind acclimate to a different kind of hormone Sparky matched Fynn's grin. “N-not what I was expecting b-but not bad!”

“You say that like I’m even done.”

Before Sparky could react, more energy overwhelmed her body, making the budding appendage of her loins throb. The jolteon fell back against the counter, rolling her head in a savage growl. Everything caressed around her insides reaching pointing ear tips and toes before rushing in a rubber band motion right between her legs. Fabric creaked in protest in chorus to her groans as the bulge grew in several powerful pulses. Stiffening tender flesh began squeezing out over the stretched waistband of her shorts, struggling to break free.

“D-damn!” Sparky barked in her labored state. She rested a hand atop the swelling meat fighting her jeans. The mere touch alone caused it to grow yet again. Both zipper and buttons snapped, causing more to shove out fighting against the elasticity of tearing blue panties. “C-come on, Fynn!”

“Yeah. I should get that for you.” The vaporeon giggled and snapped her fingers.

In an instant the pants that’d been fighting the incredibly sensitive growth between Sparky’s legs were gone. Both them and panties ballooned for a moment only to explode in a shower of confetti. A cry mixed between alarm and relief escaped the jolteon while both arms tried to grab at the unmistakable ball sack that rolled out no longer restricted. It was a wasted effort with it hanging past her knees swollen larger than a beanbag chair. She might as well have been trying to hold a marshmallow the size of a boulder.

“Much better!” Fynn teased in admiration of her handiwork. The enormous dick that now sprung from her aunt's loins was still the most impressive part of the growth. The damn thing was bigger than either of the eeveelution women combined. Even only half aroused the length still allowed it to partially touch the kitchen floor. “Don’t worry. I can balance this out.”

Before the heated Jolteon could question it, a shiver ran up her spine eliciting an adorable yelp. A rush of motion triggered an odd dizzy sensation that grabbing the counter tighter couldn’t help. The kitchen around them was suddenly getting very small very fast. Sparky kept her questioning eyes on Fynn, finding her gaze had to incline continuously downward until her snout wedged between her breasts. Her once baggy t-shirt pinched tight for several seconds before tearing from her torso and shoulders in three loud rips.

“Ah!”

Before Fynn could realize her mistake and adjust their powers accordingly, her aunt's spikey haired head had crashed through the kitchen ceiling. Fortunately, the naked jolteon fell to her bubbly ass in a daze to buy some time. Although they’d still grown large enough for their cranium to brush the freshly made skyline again by the time their niece had gotten the process to stop. Sparky shifted her hips with extreme disquiet while legs stretched all the way across the living room next door. Being on cold tile did nothing for her naked behind and tender manhood right now. Of course, the damn junk had grown with her, leaving it still oversized proportionally to the rest of her giant form.

“Y-you think we could have gone outside for this!?” Sparky squeaked. Trying to hide her breasts with crossed arms before finding the effort pointless.

“Yeah. My mistake.” Fynn never lost her energetic smile while running a hand over her aunt's shin. She had gotten them to fill up half the house in seconds and that was from such a small dose of magic. Granted the enormous cock was just her payback for the jump scare prank that’d started this whole series of events.

This was hardly anything unusual for their family either. Everyone switched or added genitals almost as often as they did clothes, just not usually at the size of a sedan.

“Why do I get the feeling this has something to do with my garden being wrecked?!”

Fynn blinked, standing on tiptoes to see over Sparky’s leg at the now open back door. The thick curved form of Amber filled up the space with a bright beam of sunlight shining over her still naked leafeon fur. Granted her attention was on the thirty-foot Jolteon filling up the place and absently stroking the length of her twitching phallus.

With but a thought, Fynn’s puppet self teleported around Sparky’s intruding limbs beside her other aunt. There was no flare or signals with it, making it all the easier to scare the dickens out of Amber when they spoke.

“Great to see you too, auntie!” Fynn moved in despite Amber’s panic, making her backpedal onto the lawn. One hand shot out to press an index finger against Amber’s tiny pink nose, scrunching their muzzle slightly. “Boop! Sparky and I are doing tests for my experiment! Hope you don’t mind joining in.”

“What? Fynn!? W-what are you… I… w-whaaa-aaah!?”

Amber’s arms flailed as her bare feet staggered across the grass. An unexpected tingle washed over her body from the vaporeon’s point of contact sending her thoughts in a spiral. Energy flowed like it was riding her blood, until it poured past her hips. The moment it reached her legs all the muscles in them unwittingly began to relax. She tried shifting her stance only for her knees to eventually buckle, falling onto her back with big leaf-like tail wedged between her thighs.

“The hell was that?” she demanded. Trying to sit up wasn’t even working right, much less standing. Amber had to prop herself up on her elbows to see what was wrong with her legs.

To her utter amazement the leafeon’s long, meaty legs were getting both longer and meatier before her eyes. Like being grabbed by some taffy machine her feet racked through the backyard grass digging little trenches with their heels. Inches piled on with every second making her ridiculously gangly in a way. Worse was how she seemed to be losing all sense of control. Amber couldn’t get her toes to twitch and bending or lifting her legs took a concentrated effort. Even when she could move them, her lower limbs felt compelled to move in unison while pressed tightly together.

Or maybe they were stuck that way. Amber cocked an eyebrow watching the seam that separated her legs wobble and suddenly vanish. The lumps that made up her knees smoothed over with the combined mass of thighs and shins filling out. Her very furred flesh warped together like putty until they were a single solid lump of thrashing muscles. By contrast her toes dwindled away into stubby lumps, which then fed into the narrowing end of a very lengthy looking lower body.

“The hell, Fynn?” Amber huffed. She tried to sit up again only to find her hips refusing to bend with any familiar joints for the position. The leafeon fell onto her side and rolled onto her front, getting a face full of her own cleavage, figures her tits would be expanding with the rest of her. With a bit of pushing and experimentation with the lengthy tube of spinal cords and sinew she got the growing mass under her enough to balance upright on it. “Are you turning me into some kind of snake?”

“They’re called Lamia’s actually.” The vaporeon’s grin never falters under her aunts accusing glare. “Since you liked nature so much, I thought it’d be a cool change for ya.”

“You could have warned me!” Amber huffed, hands running over her lower back. Like everything else about her, the rounded bump that still resembled a buttock was steadily growing big and plump to match her enormous tail curling around the backyard fence. “Ugh! Having all this tail makes my ass look fat too.”

“You didn’t need my help for that, honestly!”

“You are terrible. You brat!” Amber thrashed the tip of her tail, but only in a mocking anger. Now that the initial shock was over, she couldn’t help stroking her breasts with a delightful purring noise. Their steady growth pouring out of her palms was probably one of the few sensations that made her enjoy Fynn’s wayward attempts at science.

Neither really noticed how the leafeon’s tail coiled around the square half-mile fence at that point. The large leaf she used to sport above her butt had migrated down to the tip as a stylistic spade. Every twitch and shifting generated unintentional gusts of wind that were kicking up what remained of Amber’s flower gardens.

“So, you're going to explain yourself, young lady?” Amber crossed her arms and raised herself up higher on her ever-extending snake bottom. She had gotten even larger than Sparky now and casted a curious shadow across their house.

“Well, it all bega-aaaah!” Fynn failed to notice the clusters of pollen until most of the porch was coated in it. Her black nose twitched violently, scrunching up against her tense muzzle. Both hands clasped it too late to avoid what was coming. “GAAAAAH! CHUU!”

Apparently all five senses transferred perfectly between a remote flesh puppet and the real vaporeon casually drifting through a third of the galaxy. That was good to note for future reference. Unfortunately, the surge of power that escaped the tiny Fynn as a result washed over the neighborhood with a sonic boom type effect.

KA-THWOOOOOM!

No sooner did Fynn straighten up to wipe her nose than a large yellow leg erupted from the house behind her, taking out the glass back door and most of the wall with one monumental foot. The rest of Sparky quickly followed as parts of the family home ruptured or exploded in showers of plaster, glass, and wood.

Amber squeaked when the surge overwhelmed her own body to expedite her own growth. And then she cried out again when her sisters enlarging foot kicked her backwards into a rough landing atop her coiling tail. Their wooden fence was sent flying by an overgrowth of leafeon, the precious plants tended within becoming overturned and squashed by her crowding mass 

In just a few seconds the accidental growthsplosion had laid waste to the family home. Sparky and Amber both struggled to sit up reaching over eighty feet with just that. They gave off pained barks while wrestling debris and dirt from their sloshing curves.

Fynn could only watch dumbstruck still wedged between Sparky’s thigh and a section of Amber’s tail. This was totally unexpected but still fine. She could fix this easily with a bit more work.

The other half of their house chose that moment to finish breaking apart, mostly due to the emergence of a gigantic sized eevee women thrashing out in a wild bid for freedom. They gave a triumphant bark before rolling over to lay across Sparky’s lap, unintentionally crushing their hyper penis with an abundance of chocolate furry breasts.

“That was totally awesome!” Trinity declared as she grinned down her muzzle at the miniscule Fynn. Her breath blasted so hard it was making the vaporeon lean back. “I dunno what you did, but can we do some more!?”

This might take a lot more experimenting than Fynn thought.
