Part 3

Penelope insisted that Sonja come along to check out the Squish Sister home base. Sonja politely agreed to come along; it would be nice to meet others like herself. And if they were anything like kind-hearted Vera, then she had no particular objections.

Sonja expected a commune of sorts, like a sorority house, or perhaps a mansion for superpowered people. She hardly expected Penelope to take her to... a phonebooth?

"Are we calling taxi?" Sonja asked innocently. "I would figure after all of the stretching gymnastics we'd have no need of such-"

"No no, it's the... look, I'll show you!~" Penelope tugged Sonja along, into the phone booth. She closed the door behind them, and bent over to prod at the ground.

Sonja watched with amazement as Penelope pulled aside a tile on the ground to reveal... a pipe hole, no wider than her palm. Sonja squinted, looking it over.

"...Oh, I see, is this one of those tubes that echo all the way through? Hello!" Sonja lowered her head to call out.

"Heh, close! It's the entryway to our home base!" Penelope clarified.

"...The... entryway?" Sonja took another look at it. It was so tiny...

"Can't be a Squish Sister if you can't squish! C'mon, don't be shy!~" Penelope encouraged her, reaching over to caress her neck and cram Sonja's head into the hole! Sonja flailed her limbs in surprise, burbling indistinctly as her pliable form was sucked within, cramming itself into a long noodly length as she disappeared with a blurb.

Penelope would wait a bit until the wet, squelching sounds dissipated. It was a bit of a trip, and surely Sonja's body was being twisted in all directions following the path down, gurgling and squelching with each winding turn.

When the loud sounds of burbling and popping grew more distant, Penelope crossed her legs together, melding into a single tail, and hopped inside, her buxom momentarily catching on the rim before being violently sucked in as well!

---

Sonja wanted to scream all the way down, but her body was so compressed, stretched out, that she couldn't move her lips, or inflate her diaphragm! She was so tight!

It felt like an eternity, her body forcibly pressed through such narrow pipes, but, at some point, she reached the end, sputtering into a viscous pile of mud. She gasped, rapidly trying to pull herself back together, her chest cushioning her formless collapse onto a cool, stainless steel floor, her hips still struggling to gurgle out from the lip of a pipe.

As her thighs and toes finally slipped free, melting into the pile of mud, she slid forward, wondering where she was. It was so... big, and spacious here. Fluorescent lights lined the ceiling. The place seemed... under construction.

"Comingggg!~" The pipe behind her echoed with Penelope's bubbly voice and, gawking behind her, Sonja snapped back into focus, oozing to the side, reconstituting her melty form, as if she were clearing out from the end of a water slide. In short order, a glossy pink mass bubbled from the end, swirling elegantly as a pair of feet, followed by a strange of twizzler-like gum, twisting quickly into Popgum's pronounced, heavyset figure, as if she were being 3D-printed before Sonja eyes.

"Tada! Welcome to Squish Sister HQ!~" Popgum flourished some jazz hands with a beaming smile.

"...Wow... what is this place?" Sonja wondered aloud, glancing about.

"You probably couldn't tell, but we're underground now! That tunnel took us under and out of the city, in a seeeeeecret location!" Popgum explained. "It's so it's accessible only to people like us!~"

"I... I see..." Sonja nodded. "And, um, what is... this place? This room? It is seeming to be... lacking feature."

"Oh, it's big! This is our stress-testing room, it goes on for miiiiiiiiiiles. Everything's reinforced, so you can streeeeeeeeetch and streeeeeeeeeeeeeeeetch..."

Popgum demonstrated, twisting about in the air, before looping her arms around Sonja's torso, bringing her along for the ride. Sonja yelped with surprise at the surprisingly intimate display, and the exhilaration of zipping several feet at once. She felt her carefully-constructed human features melt away to reveal mud, clay and sand once more as her body stretched over a hundred feet in a matter of moments!

"P-Penelope... er, Popgum, I..." Sonja gawked, her muddy body splattering behind as they soared.

"You can go oooon and ooooooon, and oooo... OH! Hi Ling!~"

The stretching stopped, and their lower bodies sprung back; Sonja oozed through Popgum's fingers, steadying herself as she plopped to the ground with a sickening splat, her legs fused together into a pillar of mud. She turned to the newcomer; the Asian woman was rather striking, garbed in form-fitting orange-and-green spandex, streaks of lightning patterns travelling down her limbs. She was kneeling as if ready to start a race, butt raised and legs tensed.

"Penelope!" Ling beamed. "Caught me in the middle of something. Who's the newbie?"

Sonja blinked. She was surprised that this person was so casual about Sonja's filthy, mud-streaked appearance, so it took her a moment to remember herself. "S-Sonja Petrovich... I-I am fashion modeller, but..."

"She got turned into a squish sister pretty recently, so she's still figuring it out." Popgum nodded. "D'you think you could show her a couple things, Ling?"

"Sure! Once I'm done my rounds! Okay bye!~"

ZOOM! Ling made off like a rocket, the shockwave of her takeoff sending Popgum and Sonja splattering to the nearby wall. The poor mud girl was dazed, her slimy form completely plastered.

"Wh... what was..."

ZOOM! Another shockwave of raw speed as a green-orange blur rocketed past them. ZOOM, and again. ZOOM, ZOOM, it was accelerating!

"Ling's better know as Ms. Stretchfast!~" Popgum explained. "She's like Vera; she inherited superspeed and superstretchiness from her parents, and she's really eager to push her limits!"

"I... I see..." Sonja noted, dazed. "So she is running laps? Her cardio is spectacular!"

"Ah, that's not what she's stress-testing." Popgum peeled her head away from the wall to shake. "It's not the speed she can go that's in question, but rather, how fast she can go before she..."

WAP! SPLOT! Squelch...

Sonja gawked as Ling, on her latest pass, slipped on a green-splatter on the ground. As if playing out in slow motion, the woman's body exploded into a paint-like consistency, tumbling in a formless mass as it slide along the floor, leaving steaming streaks of ooze in her wake.

"LING!?" Sonja cried out. She tried to hurry to help, peeling herself from the wall. But her legs were stuck together, and she felt as fast as a slug. Maybe stretching would be quicker...

"You okay, Ling!?" Popgum hollered; from the misshapen mass, a tendril arose, shapeshifting into a bulbous thumbs up; she gurgled an affirmative, before collapsing.

"If you remember science class, running builds up kinetic energy and heat, so it... doesn't agree with a soft body like hers." Popgum admitted with a chuckle.

"...How many girls are struggling with this melting thing?" Sonja felt herself break into a cold sweat... or maybe she was melting herself.

"Let's give her a moment to cool off." Popgum gestured down the hall. "There's more to see, and more people to meet! C'mon, I'll show you the break room!"

"A-ah... yes..." Sonja nodded. It was hard not to worry about a person exploding in front of her eyes, but if Popgum said it was okay. This whole Squish Sister thing felt like a strange new world for her.

Entering a doorway to the side, they left the testing ground and entered into a foyer of sorts. Sonja quietly admired the style of the place; the walls were lined with framed photos and newspaper cutouts of various superheroic deeds, along with some medals and trophies off to the side. Within the display cases was an eclectic array of strange, yet mesmerizing artifacts, all seemingly points of pride. Sonja didn't recognize everything, as there were some strange alien artifices among them she didn't recognize.

The stainless-steel floor had given way to luxurious hardwood floors, draped with welcoming carpets. Sonja felt bad about perhaps tarnishing the rug with her muddy footprints, but as she stopped in place to admire, the splattered mud trickled back into her heels, climbing up her thighs.

Sonja looked at the stairwell curiously; they were enormous, each step coming up to her waistline. The stairwells had firemen's polls along them as well. She assumed that was the preferred method of getting up and down... though, based on some of the incredible feats she witnessed earlier today, she wondered if either of these conveniences were really needed.

"Is delightful looking place." Sonja nodded, smiling to herself. "Very big..."

"The place needed to be upscaled a bit for one of our bigger members, I'm sure we'll be running into her in a bit." Popgum gestured around the foyers. "We have our rooms along these hallways, and if you hang left, the break-room is-"

"Ohhh my... aren't you a succulent little thing?"

The husky voice of an older woman interrupted Popgum, and Sonja turned to find herself face to face with another woman. Sonja choked in surprise at the woman's choice of attire; she was barely clothed at all, a spaghetti-string bikini adorned with two rubies covering her fat nipples, and a narrow pair of panties protecting whatever little modesty she had left.

"H... hello..." Sonja mumbled as the woman approached her fearlessly, stopping just short that their breasts were centimeters apart. Streaks of mud trickled anxiously down Sonja's entire body as she examined the woman more closely. At a glance, Sonja noted the woman's mahogany skin tone. There was a lint of an accent in her sultry tone; perhaps she was Indian?

"Oh! Um, hi Devi!" Popgum chuckled nervously. "This is Sonja, I'm showing her around!~"

"Sonja..." Devi licked her lips, bringing herself closer; her body creaked with a rubbery groan as her torso elongated, looming over Sonja before looping behind her, cutting her off from Popgum. "In my 900 plus years walking the earth, I don't believe I've ever seen a creature such as you...~"

"U-um...!" Sonja froze up, Devi looking all the part of a snake stalking its prey.

"Hey, go easy on her, okay? She just mutated, so she's still getting adjusted to her new body!" Popgum pointed out.

"Mm? She need only speak up, and I will back away..." Devi purred, her well-manicured palm hovering over Sonja's stomach. "I merely wish to explore her a bit..."

Zzt! Sonja was zapped with a small shock. She yelped and instinctively jutted upwards, her body stretching towards the ceiling and arcing over Devi's coils, before splattering away. The corner of Devi's mouth curled upwards in an approving smile.

"If she's a new seedling, then she is settling into her role nicely..." Devi noted. Popgum hurried to Sonja's side.

"Wh-what was that shocking feeling?" Sonja murmured, cupping her tummy. "I feel tingly..."

"Ohhh, a harmless indulgence of my curiosity..." Devi licked her lips, pacing over to loom over her. "You should be feeling the effects of my spell momentarily~"

"Spell? I don't... u-uwah!?" Sonja cried out sharply as, before her very eyes, her stomach began to swell, as if being filled with something from within. In a matter of moments, she went from having a slender figure to bearing a full-term, healthy pregnancy! She gawked, astounded at her growth, helpless as Devi reached down.

Sonja whined as Devi's fingers dipped into Sonja's overly-soft flesh. Something was shifting inside of her; peeking through one eye, she saw Devi pulling back, wresting a... a ripe watermelon? Did that... grow in her stomach?

"My my, how fertile you are, Sonja~" Devi chuckled, stroking the watermelon. "The fruits of your labour will nourish our family well... perhaps I can... explore your body a little more later~"

Devi chuckled, turning her back to the other girls as she paced down the hallway, her braided black hair waving behind her. Sonja felt around her flat stomach; it was fine, seemingly untouched...

"What... what was that spell...?" Sonja gawked.

"Devi is, uh, a spellcaster, you see..." Popgum explained, helping Sonja off the ground. "She says her powers and her... immortality... came from wishing upon a magic mirror. She's all about those worldly pleasures, you see, and..."

"Oh, so she is hedonist." Sonja nodded. It was nice to understand what was going on.

"Um... well, yes." Popgum chuckled. "Not how I would've put it, but... ah..."

Sonja cupped her stomach as she rose to her feet. Though she was spooked by the episode, she was ultimately unharmed... still, if she could rattle Popgum of all people, she must've been the interesting character indeed.

"C'mon, I'll show you the kitchen!" Popgum clasped Sonja's hand, hurrying her along. "Trust me, we got some wild appliances in there!"

"Oh? You have air fryer?" Sonja smiled. "I am fan of crispying my veggies, hehe!"

"Better!" Popgum beamed. "You gotta see it to believe it!"

---

As the two girls headed into the kitchen, Sonja's expectations were a little inflated from all the hyping Popgum did. And sure, it was well-equipped, and as spacious as the rest of HQ she had seen. It did look modern and sleek, with the pretty marble countertops and stainless steel appliances, but she didn't see anything that was super surprising. She recalled staying in places like this on and off when she was travelling for modelling, actually.

However, those comparative thoughts wavered when her eyes settled on an enormous alien creature, looming over one of the countertops, their back turned to her. Truly, the creature was nothing like Sonja had ever seen; towering over nine feet tall, they were covered in marbelly blue scales. Sonja's eyes followed a massive tail as thick and tall as she was, nestled between two beanbag-sized, ending in talon-like feet with three toes each. A protruding, beach-ball gut hugged the creature's curves, and even from behind, Sonja could tell this alien creature was developed, noting the curvature of scaly breasts, each the size of a medicine ball!

"Hey Kess!" Popgum waved cheerily. "Still working on the matter transponder?"

Sonja continued to gawk at the magnificent alien beast, her name and the idea of a "matter transponder" sailing well over her head. Popgum took Sonja's hand and pulled her along, the shocked malleable girl leading a trail of mud behind her.

"The modifications are just about complete, actually." Kess responded in a deep, bellowing voice, her torso stretching upwards and across the room in a pretzel twist as she turned to Popgum; all of her assets jiggling in unison, she surveyed the newcomer with a pair of beady black eyes. "...Oh? Is this a new cadet?"

"S... Sonja Petrovich, ma'am." Sonja muttered, feeling utterly dwarfed by this alien creature. "I-I am no cadet, um, merely fashion model, so..."

"And yet you are here now." Kess muttered, her heavy footsteps catching up to her stretch torso. As she fully retracted, her chitinous-shoulders went slack. "My birth name is Kess. I hail from the distant star system BE-827, though a small settlement of our people resettled in the terran colony of Othar."

"Ah..." Sonja nodded carefully. Being in the presence of an actual alien, one that could crush her without so much as a second thought, was terrifying to be sure.

"Kess is a kobold! And she's both our brains and brawn, y'know!" Popgum beamed. "Her people came up with a whole buncha special tech, and none of us here know how to use it."

"Is that why you have me reprogram the microwave?" Kess glowered, her neck stretching to stare down Popgum; she looked like a dinosaur, looking down upon Popgum like a scene out of Jurassic Park.

"W-well, I mean... you read the instructions, right?" Popgum looked for a way to distract the kobold, and then she had an idea. "Hey, that matter transponder's good, right? Show Sonja how to use it!"

"...hrm." Kess grunted, stomping to the side and gestured to the counter. Sonja approached carefully, eying the curious machine in front of her. It had an alien blue glow lining it, like something out of a scifi movie.

"The matter transponder takes basic matter and reassembles the molecules to take on any shape. It's versatile technology, but it needs to be directed to be any useful... or otherwise, mistakes happen, like a half-formed frog." Kess' expression flattened. "I have reprogrammed it. It now scans the person, and from the air itself, generates for them what they're craving most."

"...um?" Sonja blinked. "Like... magic?"

"Not like magic!" Kess bellowed. "It is advanced kobold tech!"

"Lemme demonstrate!" Popgum dipped between Kess's enormous legs, pressing the big red button. It glowed and hummed for a spell, before opening a latch, revealing a pair of peanut-butter and chocolate cups. She swooned, unhinging her jaw to scarf both down at once.

"Shee? Eashee!" Popgum mumbled as she chewed; Kess's face contorted into an expression of mild disgust. Sonja nodded in turn, and approached the panel.

"Is it that easy...?" Sonja pressed the button, recoiling her muddy finger as it buzzed. Was she just scanned? The machine whirred to life again, exactly as it had for Popgum. Perhaps it was taking a little longer to process something for Sonja.

"Maybe it doesn't recognize me..." Sonja murmured.

"Give it time. It needs to make a new profile for you." Kess explained. "It may be slow on the first time, but rest assured, its processors are faster than any human parallel. It's certainly smarter than you."

"...oh... great..." Sonja's eyebrows furrowed. Maybe kobolds weren't as accustomed to human etiquette... she thought about saying something about Kess's tone, but an affirmative DING! distracted Sonja, and she turned to see the latch opening to reveal...

...A bowl of... soil?

"What?" Sonja blinked. "Is it broken? I was expecting shrimp cocktail...!"

"I just fixed it. It's right." Kess grunted. "Take it."

Sonja stared for a spell. She glanced to Popgum, and then back to the dirt. There was that familiar feeling of dread that welled up, from when she met Vera. How her body wasn't taking to real people food. If she was a being of mud, clay and sand, then maybe... oh God...

With trembling hands, Sonja took the bowl, examining it closer. She didn't wanna eat dirt! She was a celebrity! She had caterers! Sure, it didn't smell awful, and the earthy aroma was pleasant on her senses, but she'd get ill if she-

"Bottoms up!" Popgum encouragingly tipped the bowl towards Sonja's open, agape mouth, gurgling as a mouthful tipped into her mouth. Sonja struggled, trying to break away... but stopped as the soil hit her tongue.

Though her brain was screaming that this was wrong beyond measure, her sense of taste... didn't disagree at all! It had a silky texture to it, and a pleasant taste like pudding. It practically melted in her mouth... actually, maybe it was literally melting in her mouth, sinking into her tongue and the sides of her mouth. Her entire body buzzed with a pleasant buzzing feeling, and a gentle warmth settling in her gut.

She tipped the bowl again, taking on another mouthful.

"Exquisite..." Sonja murmured. "This... this is what I've been craving?"

"Women of the earth take to the earth." Kess mumbled. "It's not a big surprise. Unless you still wish to place more doubts on my technology?"

"U-um, no, I'm..." Sonja trailed off as she looked up at the kobold. Kess was clutching a bowl of her own, pulled from the matter transponder. Whatever it was, it was alive, squelching and wriggling, suckered tentacles writing on their own. As one coiled around Kess's talon-like finger, a muted screaming could be heard as she slurped it up. Her tail elongated on its own, coiling into a pile as it stretched to triple its length, and she sat down with a heavy fwump on the pile of scaly coils.

Sonja's stomach twisted, and she hugged her bowl closer. "I-I am good, for now..."

Sonja's body had become so strange. And now she was going to have stranger company still. She hoped she could fit in, and make herself useful, somehow...
