Scarlett was on her back, tinkering under her car. She wore the blue tank top and bandanna she usually wore for shop work. She adjusted her wrench, continuing a long morning of tinkering, rebuilding, and improving.

"Alllllmost finished...just a little tighter here..."
*CRRRRRRANK*CRAAAAAANK*
*creeeeeeeeeeeeeeeeeeeeak*

As always, Scarlett was completely, mentally when not physically, absorbed in working on her car. As such, she was oblivious to the door creaking open, and Amber walking in without any clothes on.

"Scarlett? You in here babe?"

Amber paused, listening for any sort of response. All she heard were the metal cranks and clangs of machinery.

"Perfect."

It was easy for Amber to scamper across the room on bare feet without being heard. As unfortunate as it was Scarlett didn't see her curves swinging back and forth with each step, Amber wanted to see the great melting up close. She found a clear table near Scarlett to lay seductively across, collecting a few toys as she did. She slid a nearby air tank next to the table, ensuring the hose and valve were within reach.

*cough---ach-hem* Amber cleared her throat, before dropping her voice to the sultriest tones she could muster. To be sure Scarlett heard her, she also slapped her butt as hard as she could, echoing the clap around the room.

"Heeeeey Scarlett. Want to try a race when you're done there? I bet you can't squish this with that fancy car."

The cranking gears didn't stop under the car, but Scarlett at least responded. "That you Amber? I'll be out in a moment, I'm almost done with this."

*That's my girl.* Amber smiled and rested her head on her arm, propped up by her elbow.

"Yup. Just checking in. Let me know if you want to take a break and loosen up, if you know what I mean."

*CRANK*CRANK*

"Just another minute. I need to double check this chain, then check the air in the tires. I guess you could help with that if you wanted to speed things up."

Amber grinned, twirling the air tank's hose with her finger. "Sure thing babe!"

Naturally she plugged the hose into herself, not the tires, then opened the air tank's valve.

The air hit her chest first, puffing up her breasts. They pulsed larger with each breath, expanding outward, giving Scarlett something fun to melt over. The skin of her orbs rippled as they grew, making Amber smile at the stretching sensation and the rubbery sounds of herself ballooning larger. Once her cup size reached the end of the alphabet, and even her stiff inflated nipples filled tight with air, Amber directed the flow to her butt. She needed something to squish Scarlett with if she stayed solid, and her newly pneumatic hips would do. They too rippled wider, stretching and filling with air, pressing against the table to huge sizes. Amber felt the fires of lust warm inside her just thinking about it, idly wondering if she would melt faster than Scarlett if she ever saw someone with an ass as huge as hers.

Soon after achieving a hyper hourglassed figure, Amber felt the the rest of her body grow puffy. Amber waited for her limbs to take on a rubbery shine, then killed the air flow before she lost any more mobility.

"Oh hey, you're all done? That's great I just finished, I'll be right out."

Amber raised an eyebrow at Scarlett's voice. *She can't hear me walk in the room or tell I inflated myself, but she heard the air flow stop?*

She unplugged herself from the hose, and looked to car. Scarlett's legs were sliding out, as promised.

"Almost set! I just need to check the pressure, make sure it starts, then put some large metal carriage thing back in and...and..."

Amber's eyes met Scarlett's. She rubbed her inflated breasts, purposefully making loud squeaky sounds. "You sure kept me waiting. What are you going to do with all of this me?"

*PLOP*

Amber smiled. Scarlett was already dripping to the floor.

"More importantly, what am I going to do with your goopey puddle?"

Scarlett was melting fast. Even as they melted with her, Scarlett's clothes were failing to contain the rest of her liquefying body.

"I already pushed...the button....oh Amber..."

Amber smiled at her melty girlfriend, but had to wonder...

"What button?"

The sound of metal chains rattling over her head made her worry. She looked up and saw a heavy metal frame falling straight towards her.

Amber huffed, making some of her inflated hair wobble more than flutter. "This is going to more than just flatten me isn't it?"

The frame indeed pushed its way through Amber to the table, pinching her stomach to her back, putting immense pressure on her inflated curves. All the air forced away from her breasts and butt filled her legs, her neck, and whatever parts of her belly weren't pinned down. Amber's eyes bugged out too, two huge white and green balloons in a sea of inflated flesh.

Her whole body trembled, completely out of capacity. The last thing she saw was Scarlett, by now a all but formless blob on the floor, with big eyes staring right at her.

*BOOOOOOOOOOM*

Amber's body exploded apart, popped into scraps of toony flesh scattering across the room. Her confettied body fluttered around, with much of her butt landing in Scarlett.

That, plus the force of her explosion sending ripples through Scarlett's smiling goop, was enough to dissolve Scarlett's head into the rest of her puddle.

Her eyes turned into blue hearts, spreading across her surface. "You've gotta let me know when you're going something fun babe...*siiiiiigh*.

* * *

Eventually Amber's scraps crawled together for a patch job on herself. Some reforging of liquid Scarlett later, and the ladies were back at it. Amber donned her usual yellow tank top and pink shorts, then they did legitimately inflate the tires. Then they returned to the matter of the giant frame.

Scarlett smacked the hood of her bright red car. "Okay, the real reason I'm glad you checked in? The frame that popped you is supposedly reinforced steel. That should keep the car in one piece when I crash so there's less rebuilding next time."

Amber raised an eyebrow. "How many times have you been reduced to ash in this thing now?"

"Seven. But its crushed me so much I oozed out the wreck a few times too."

It wasn't lost on Amber that Scarlett didn't miss a beat, blush, or show any of her usual excitement for getting gooped while tending to her car.

Scarlett finally stopped staring at the car and looked at Amber. "The machines here can handle it, but if you wanted to help out, I could use someone big and strong to take apart the car's body."

Amber laughed. "So what can I do to help? Get huge and snap off the top like a child's toy? This feel out of my-"

Scarlett beamed, not letting her finish. "Exactly!"

Amber blinked. "Wait, is that how this really works?"

"Of course not!" Scarlett muttered, rolled her eyes. "Runners thinking they know how things work and..."

She pushed a button on a nearby remote. A crane swung over with a large magnet, lowering it on top of the car. Some strange science noises and a metal CREEEEAK later, and it removed the exterior body work, exposing the existing chassis and engine innards.

Amber absorbed the sight, scratching her head. "Oh...that's...not what I expected."

"Well, don't just stand there!"

Amber turned around, discovered Scarlett had walked next to the frame, still resting on the table where it burst her inflated curves apart earlier.

"Get big and install this on top of the rest!"

"Pffft, fiiiiine!" Amber laughed, closed her eyes, and focused. She thought about tripling in height, and a soft pink glow surrounded her. She felt her body growing, stretching up and out within the garage.

Scarlett licked her lips, watching specific parts her girlfriend getting bigger, imagining how she could melt all over them...after the car work of course.

Amber stopped once she hit 15 feet. She reached down with two fingers to pluck the frame off the table. "So I just take this, and..."

Scarlett scampered up her arm to sit on her shoulder. She waved her arms around, directing Amber back towards the car with exaggerated motions. "Just snap it over the rest. I got this custom made, so it should just..."

Amber followed Scarlett's hands, placing it neatly over the rest of the car's interior.

*CLICK*

Amber smiled. "Perfect fit!"

Scarlett stood up on Amber's shoulder, and nuzzled her cheek. "Thanks babe!"

Scarlett leaned her whole body against Amber, practically hugging her face, before grinding into Amber's cheek with her hips. Amber started giggling and blushing, more than happy to feel Scarlett's cute butt.

Even if it was really distracting.

"Hahaha!--Heeeey!--Ahahahahaha! Let be shrink back to normal size before you fall and splat babe!"

Amber's decent to normal size was choppy. Bits of her slurped into her self, getting smaller randomly. Within seconds, that included the shoulder under Scarlett. Trying to avoid becoming that splat, Scarlett jumped and hugged Amber's shrinking head.

"Hah! Whoa there, hold your horses! Before you try and smother me with those." Boobs in her face was too much for even Amber. It wasn't that she melted, but...

*SHHHHHRRRP*

Amber snapped back to normal size, all of her mass slurping together like spaghetti ten feet in the air.

Right over the car's engine.

"YAAAAH"
*SQUIIIIIIIISH*

Scarlett and Amber's bodies couldn't maintain their shape, forced into narrow openings in the engine. Their upper bodies expanded from the extra mass shunting up while gravity squeezed them in.

*THOOOMP*
*CLANG*

Naturally, the car's body fall back into place soon after.

The car shook around a moment later. The ladies tried to fight their way out of their new steel prison, making the car honk, the lights flash, and even make the engine roar once. With one last loud rattle...

*FWOOOOOOOOOOOMP*

Two fleshy air bags deployed from the front seats of the car. Scarlett's huge inflated breasts, barely contained by her stretched blue tank top, deployed from the driver's side. Amber's came from the passenger. Both fleshy racks rippled from the air filling them, until they were huge shiny balloons. With one last *FWOOOMP*, their nipples inflated out the front too.

Big puffed up eyes opened at the top of each pair's cleavage.

Scarlett's blue rumbled as she spoke. "Heh, sorry."

Amber's wobbled in kind. "Babe? I know you're into cars, but this is ridiculous."

* * *

After extracting themselves from the car, Scarlett returned to tuning the car. She had many more tweaks to make, from securing the new reinforced frame, to adjusting the suspension for it, to her obligatory engine enhancing tweaks...

Which, as time dragged on, left Amber standing around tapping her foot. "Scarlett, are you almost done yet? I thought you said it was just one quick thing!"

Scarlett's response was metal cranks and clangs from tinkering. The red headed mechanic's voice was muffled muttering. "It is, I just keep finding one more thing I don't want to forget and...wait is that belt loose?"

Amber rolled her eyes again in frustration. "There's gotta be some way I can get her outta there...ugh, I guess if I want to leave soon..."

She looked around, spotting the garage's lift, conveniently with a heavy steel bed.

"I mean...I already haven't stayed solid today, so I might as well enjoy this."

Amber clicked the automatic lower and raise buttons on the crane, a function that might seem strange to those that didn't know the ladies better, then got into position under the rectangular platform. She closed her eyes and smiled as the platform firmly pressed her body into the floor, slowly squishing her smaller and wider, as if made out of play dough. Amber felt her breasts expand against her shirt, and her butt growing and escaping her shorts. She even felt her heart flutter as soft fabric squeezed her squishy body.

She used her now stubby arms to hug her huge squishy assets *This massage is totally worth it!*

Still, she had a mission. "OOOOOOOH! Scarlett! I'm getting flattened by this thing! My boobs are going to pop out of my shirt from this, OOOOOOOOH it feels really good but I can't escape. Heeeeeeemmmmmph!!!"

Amber laughed when her head was finally squished into her growing breasts. She felt parts of her merging together, molding into a big pink and yellow pancake. She figured she had to look ridiculous, a giant pair of yellow boobs and a big pink butt, huge jiggly orbs getting pressed flatter and flatter until...

*SQUIIIIIIIIIIIIIISH*

She could feel her edges escaping, a slimy film of herself oozing around the outside of the crane...but she heard no reaction from Scarlett.

The crane lifted up, exposing Amber's flattened face to the ceiling. Her head really was a tiny circle between her huge rectangular chest, massive square butt, all of her mass forced into her fun areas except for two tiny arms.

That didn't stop her from continuing with her sexy voice. "Scaaaaarleeeett. I'm huge and flat and helplessly stuck to the floor! Try not to tear me and peel me off the floor!"

Her only response was more metal clangs of the red head tinkering. "One minute babe, I said I'm almost...ah shoot that needs to get fixed NOW. Give me a second here..."

Amber scowled. She peeled her arm off herself, and *POP* shook it back into three dimensions. She jammed that thumb in her mouth, took a deep breath, and with one hard blow made her flattened body shake and inflate almost like a raft, until

*BOOOIIIIOOIIING*

Amber snapped back into shape.

She adjusted her clothes and shook the cobwebs out, then looked around again. "I can't believe you let me flatten myself for nothing babe! Come on now...oh, I've been meaning to try this."

Amber pulled another lever, lowering a very specific contraption to her level. It had flat metal heads opposed to each other for pressing things, almost like jack hammers. "I can't believe you haven't noticed this yet. It took 4 trips here after the last 5 times you blew up your car to make this work. Now..."

Amber stepped inside the machine's work area, against a human shaped outline opened to the front. She put her hand near the on switch, and again shifted her voice to teasing Scarlett.

"Oooooh Noooooo! Scarlett! I'm caught in these jackhammers!"

She flipped it on, and a loud rattling sound filled the room. "Help, I'm coming apaa-aaaa-rrr-rrrtttt-t and it feee-eeee-eeee-eeels sooo-ooo-oooo-ooo..."

She didn't have to fake it. She machine was rattling Amber's body around, each individual strike too little to flatten her, but enough to throw her into the opposing one. Amber focused on staying solid, which she knew was the worst thing to do in these situations.

Cracks ran through her, the rattling force too strong for any toony body to withstand. Her voice got more distorted as lines crept through her chest, and the tingle of her body coming apart overwhelmed her senses. Tiny piece of her chipped away, a shard of pink bouncing one way while a fleshy suntanned blob of yellow bounced another.

"I-I-I-I-I-I caaa-aa-aaa-aan't hooo-oo-oo-ld ooo-ooo-oon-OOOHHH YEAAAAAAH!!!"
*CRSSSSSSSSSSSSSSSSSSHHH*

Amber held herself together as long as she could, but after a few seconds it was no use. One last strike shattered her body apart, sending a flood of Amber colored shards across the floor like spilled beads.

For a moment she was completely knocked out, too turned on by her body breaking apart into hundreds of pieces to know what was happening around her.

For Scarlett, the strange yellow rocks crashing into her were a minor annoyance. "Ack! Hey babe, watch out for this weird sand stuff! I don't want it messing with the engine."

The next thing Amber sensed was something brushing chunks of her along the floor. She pulled her head together somewhere near the machine, pink sand and yellow chunks glomping together into a goopey head shape, giving Amber a look at...

"ARE YOU SERIOUSLY JUST BRUSHING MY BODY AWAY?!"

Scarlett was indeed kicking piles of blond out from under the car.

Amber was actually getting angry now, turning slightly red. "You know, usually it's cute, but come on! I put a lot of effort into that one!"

"In a minute Amber, I'm getting this weird sand out of the oil filter."

Amber growled. Her shattered body started shaking, swirling into a whirlwind of Amber colored chaos. It picked up her reformed head, then started growing. Amber flexed an arm out of the wind into a giant beefy bicep. Then huge legs with strong thighs. Then her chest and the rest. Soon 15 foot tall Amber was back in one piece, and she was tired of waiting.

She lifted the car. "Scarlett! Did you seriously not see me down there?"

Scarlett, still on her back looking up, finally realized her situation. She dropped her wrench, letting it clatter to the floor. She picked herself up with her arms, then felt around where her hand was.

She picked up a pink shard that matched Amber's shorts. "Oh, you mean...wait what happened to you?"

Amber calmed down a little at her cutie's remarks, but she was too invested in her growth rage to stop now. *She actually is cute when she's oblivious, but I'm already huge...she's getting squished.*

She kneeled next to Scarlett, placing two fingers near Scarlett's mouth. "You worked right through me squishing and shattering this body for you. So now we have to answer an important question."

"Are you into your car more than it's into you?"

Scarlett looked thoughtful, not sure how to answer the question. "Well, a vehicle and its driver are inseparable an-WHOOOOOOOOOOOOAAAGAAAAA"

*STREEEEEEEEEETCH*

Creaking rubber noises accompanied Amber stretching Scarlett's mouth open to impossible sizes. Once tiny Scarlett's mouth was open ten feet, she jammed the car in.

Scarlett's body shifted around like a cheap burlap sack. The back of the car stretched her butt into a huge long rectangle, parts of her cheeks springing into the air to form the spoiler. Her legs shrank into her growing hips, then immediately transformed into fleshy tires.

Scarlett's stretchy face twisted, half discomfort half pleasure, feeling her body's changes behind her. She arched her elongating back, which inverted wobbling like sheet metal into the roof. Her stomach twisted and split apart into pipes under the car. Her chest was stretching around the hood, leaving only the windshield visible in her mouth.

Once Amber saw the hood squeeze through Scarlett's lips, she snapped Scarlett shut. She made sure to pull Scarlett's lower lip over to the top, staring at Scarlett's exposed cleavage painted on the hood. Scarlett's head rippled back together, sealing the car inside her, and...
*POP*

Amber placed her on the ground. "There. My very own Carlett."

Scarlett, her eyes taking up the entire the windshield, blinked. "Whoa...I knew this happened with pool floats but..."

Amber watched Scarlett wiggling various parts of her car body around. She shrank down to size, rubbing her forehead. "My goodness, you really are that absorbed into your car."

Scarlett the car wiggled the entire back half of herself. "Check it out! I can actually shake the junk in my trunk!"

Amber slammed her left palm into her face. "I made a huge mistake didn't I?"

"Only one way to find out! Let's get to the track!"

Scarlett looked towards the exit and started rolling. Slowly.

"Uuuuuh...can you drive me?"

Amber slammed her right hand next to her left. "Seriously?"

Scarlett looked at Amber, clearly embarrassed she couldn't move very well on her own. "Uuuh...you get my engine going?"

Amber walked over and opened Scarlett's blue door, but shook her head. "You're only making this worse you know."

"I want you inside me."

Amber slammed the door. "Keep it up and I'll crash you at high speeds, hoping my ashes get scattered far away from you."

* * *

"WOOOOOOOOOOOOO!!! THIS IS GREAT!"

Scarlett the car was having the time of her life. The blue and red blur continued circling the track at hundreds of miles per hour.

Unfortunately, her driver wasn't used to this. Once Amber got her new car to stop, she slumped, squished wide and thin against her seat. She looked down to confirm her sinking feeling was her body oozing apart. "Hey babe? I think I'm only one inch thick, and my tummy just gooped on me. Can you open the door before I-"

"Already on it. Don't stain my seats hon!"

*Click!*
*SPLOOOOOORT*
*SPLAAASH*

Barely holding herself together anyway, Amber let her body collapse out of the car. She more poured than fell out, pooling in a puddle of yellows and pinks on the pavement.

Scarlett's grill grinned. "Ooo! Ooo! I wanna see!"

Her tail pipe wiggled, and Scarlett slowly moved back, circling to look at her gooey beloved, accidentally stretching her puddle into a trail of pink droplets.

"Daaaw you're so cute reduced to a puddle! Usually I'm the gooey one and I never get to see this!"

"Amber's green eyes formed on top of the puddle, and managed to stand up in surprise. Her voice bubbled from her liquid lips. "Wait, I feel something stretching...Scarlett! How much are you moving on your own!"

Scarlett's engine revved in surprise, making her car body jerk backwards. "Oh hey! You're right! Maybe I'm starting to get this."

Scarlett drove up to the rest of Amber with uneven bursts, like someone first learning to drive. She got up on her side wheels to pour the rest of Amber out, then worked on moving at smoother rates.

After two wide circles around Amber, she was starting to get ideas. "Hey, how long until you get yourself solid?"

Amber's puddled mess was actually already sorted out by color. She looked less like random spilled ink and more like a wet painting of herself. "Not much longer. Fortunately I've been in your car enough to know how I react to high speeds."

Over the next minute, Scarlett worked on progressively wider turns, while Amber's body congealed on the pavement into a normal shape. One she felt solid enough, Amber loudly peeled herself off the ground.

And immediately started stretching.

"So, how fast can you go now? You know I've been prepping for sprinting season."

Scarlett's engine revved. LOUD. "Only one way to find out. LET'S GOOOO!!!"

*SQUEAK*
*SQUEAK*

The red and blue race car lurched forward at embarrassingly low speeds.

"Uuuuuh...I'm still working on the go fast part."

Amber sprang to her feet and hopped a few times. "Alright then, let's give you some inspiration."

*ZOOM*

Amber took off, leaving a trail of fire where she started. Scarlett was left in her dust, blinking at her woman's legs spinning so fast, they looked like a single pink wheel under her butt.

The Blond Blur seemingly swiveled around on her lower wheel, windmilling her arm to encourage Scarlett to get moving. "Come on babe! You're a car for crying out loud, come catch me!"

*HOOONK*

Scarlett sighed, letting out an involuntary honk. "No fair! I've only had this shape for an hour! Just you wait! Come on me, you're my car, I just need to find the turbo..."

*RRRRRR*

Scarlett was slowly gaining speed. Even though Amber was blazing a trail around the track, she wouldn't give up. *Come on me! You got transformed into a car for crying out loud. LET'S GO!*

*FWOOOSH*
*VRROOOOOOOM*

Through sheer willpower, Scarlett finally got her boosters going. Amber was still moving fast, but Scarlett was catching up.

Amber heard the engine roaring in the distance, and chanced a look over her shoulder. "Atta girl! Just a little faster if you want to catch up to this!"

Amber gave her butt a good slap.

*RRRRRRRRRRRRRRVVVROOOOOOOOOOOOOOOOOOOOOOMMM*

That was all Scarlett needed to find another gear. In not even two seconds she was right behind Amer.

"Whoa! Maybe not that FFAAAAAA-"
*SQUIIIIIIIIISH*

Amber felt Scarlett's front bump her in the butt, tossing her to the ground. Amber tumbled across the pavement, feeling lucky she stayed intact, even though she knew what came next. Scarlett forced her way over her, compressing Amber's squishy body down until the tires finished the job. Even better for Amber, she could feel her everything spreading on the ground again as she flattened, making that pink clad butt an extra large pair of pancakes.

She could swear she felt Scarlett's hand-tires give her a playful squeeze while turning her into a large Amber painting on the track.

*Mmmm...I wasn't sure she had it in her to spread me this thin! Maybe we need to do this more often.*
*SQUAAAAAAAAAAAASH*

Amber felt the car finish her off, leaving her hands flapping in the breeze while most of her was pressed into pavement. "You know, you're pretty good at this. Maybe we should see if Zoe will go for being street art after you're done-ACK!"

*SPLAAAAAAAAT*
*SQUOOOOOOOSH*
*SPLOOOOOSH*

*I always like a good stretch but this-MMMPH-...is ridiculous...*

Scarlett wasn't concerned with what Amber had to say, even if she would have liked it if she heard it. Instead she kept going fast, doing more laps, and stretching Amber's paper thin body further and further across the track. Each pass splattered Amber more and more, blurring her features from recognizable runner to random splotches of paint on the road. Each pass splashed more of her colors around, printed her into yellow and pink tire tracks, and muddled her thoughts more and more.

* * *

Fifteen minutes later, Zoe and Jess arrived to check on their team mates. Not seeing anyone in the garage but hearing the roar of an engine, they checked the track. There they saw Scarlett, still morphed into her car, speeding in circles.

Jess blinked, scratching her head. "Wait, wasn't her car all hot-rod red? Did she...?"

Zoe nodded slowly. "Yup. We can ask her later. There's one thing I need to try though."

Jess watched Zoe springing into the road. Then she did some quick math on Scarlett's speed vs Zoe's structural integrity...

"Zoe baby, are you going to be okay for tonight if you do that?"

Zoe shrugged, jumping into Scarlett's path. "Maybe, but we need to stop her and this looks like it's going to feel wonderf-OOOF"

*SPLOOOOOOOOOOOSH*

Zoe's body exploded into a mess of gooey colors, raining tans and blacks, littering the track with more goopey mess.

Zoe's voice emanated from her messy excuse for a body. "Aaaaaaaaaaaaaaaaahhh....that felt goooooood..."

Jess looked back to Scarlett, now stopped and looking very surprised. "You know, I don't think I've ever seen a car blush before."

"Heh...I guess I wasn't expecting to splatter two people today like that."

That won a laugh from Jess. "Hah! Is that why I don't see Amber? Where is that girl anyw-"

*SQUISH*

Jess felt her foot sink into something. "What...that felt way too soft for a normal track...uh oh."

She took a step back before kneeling down. The yellow stripe she was standing on had a single green eye staring up at the sky.

"I knew I didn't remember this track having yellow stripes. Amber, are you okay? Just how thin did Scarlett spread you?"

The eye slid towards Jess, looking up at her. "Heeeeh...massage...good..."

Scarlet laughed sheepishly. "I guess I overdid it."

Jess rolled her eyes. "Just promise you'll do the same to me after we clean these two up."
