Amber and Jessica got out of the van and approached a large brick standalone building, standing near an even larger house. Neither of the ladies were in their uniform, since this job was actually in Scarlett’s Uncle’s garage. The property holding it was huge, holding at least those two buildings, and what appeared to be a “small” private race track not far away.

It was Jessica’s first time here, and she was still taking it all in. “This is huge! Is this really her uncle’s place? He actually trusts us to do car maintenance when he can afford this much?”

Amber smiled as she opened the door to the separate garage building, itself the size of a school gym. “Yeah. She’s been helping him out for years. We figured you would want to check it out. The cars need some touch ups, and Scarlett put in a good word for us.”

Jessica was still looking around outside before going in. “Wait, he has a track on the property too? Look, not that I don’t appreciate the invite, but isn’t this more of a you and Scarlett gig?”

Amber pointed to the corner of the garage, “Nah, I need an assistant that’s going to get the work we were paid to do done.” Scarlett was already in the corner, hair tied back by a bandanna, tinkering with a red convertible. “I think she’s going to be busy with her car.”

Jessica stared at Scarlett, stunned that her clumsy roommate could build such a  vehicle. “You’re kidding me.”

“I keep telling you and Zoe that she’s a good mechanic.” Amber pointed outside over her shoulder with her thumb, “How do you think that old equipment van keeps running? She’s been working on that convertible for a long time now. I think she loves that thing more than me sometimes. You should ask her for a ride later, it goes pretty fast.”

Jessica looked at Amber suspiciously, and yelled “HEY SCARLETT, HELP ME OUT OVER HERE, AMBER’S MELTING AGAIN!”

Scarlett continued working on her car, as if Jessica and Amber weren’t even there.

“Wow...”

Amber lightly punched Jess on the shoulder “Told ya. Now knock it off, let’s get to work.”

* * *

Amber started filling buckets with soapy water to wash the cars, while Jessica went to grab some towels. She was almost done when there was a clang from Scarlett’s corner.

“You okay Scarlett?”

Amber heard Scarlett shuffle out from under the car and stand up, and saw her head with a circular dent in her bandanna. “Yeah, just had trouble reaching something.”

Amber nodded, “Alright fix your head and be careful!” Scarlett smiled and blew into her thumb, her cheeks puffing up before her flat top popped back into shape.

Jessica came running back into the garage. “Alright Amber, let’s do this!”

“Thanks Jess. Toss me some of those?”

Jessica counted out a few towels and tried to toss them to Amber. She also kept running right into a bucket. “Alright here we gooooooooo!”

Jessica managed to not trip, but kept all of her momentum. Now she was going full speed on a slippery soapy shoe, straight towards the wall.

*SLAM*

Amber winced at Jessica’s predicament. She was a twice as wide decal of herself on the wall, every inch of her body flattened.

Amber slowly walked over, “You okay Jessica?”

Jessica’s head started peeling off, flopping down her back. “Ooof... yeah...  nothing I can’t handle.”

Her body kept peeling off the wall, drooping backwards. Once her arms came loose she got a thumb into her mouth, and *POP* got back into shape.

Amber laughed and shook her head, “You really do need to watch where you’re going Jess. Don’t damage the cars!”

Jessica looked embarrassed, “Oh shoot! I wasn’t thinking about the old cars.”

“Right. Here, these cars on this end are the fancy ones.” Amber handed Jessica a bucket, and pointed in the opposite direction. “Go work on the big truck over there, it’s not meant for finesse. Just get soap and water on it.”

“Not meant for finesse? Are you suggesting something, Amber?” Jessica gave a mock scowl and marched towards the big truck in the corner. She made sure to swing her hips, getting Amber to laugh.

“Just clean it! That thing is big and meant to be in rough situations. Should be perfect for you.” Amber gave a playful wink for emphasis.

Jessica stuck her tongue out at Amber and turned to the truck. It was a pickup with ridiculously oversized tires, each at least 4 feet wide and 6 feet tall. It was essentially a small monster truck. “Whoa. You’re not kidding this can handle tough stuff.”

The ladies got to work on the cars. Jessica was pretty careful not to scratch her truck, not wanting to make a bad impression her first time here. There were too many fun toys in here, and she was hoping to play with a few before they left.

Jessica’s caution made the flat front tire an anxiety raising discovery. “Oh no...”

Amber looked up from the car she was working on, “Something wrong Jess?”

“Nah, everything’s fine. Truck just has a flat in the front.” Jessica was looking around nervously. It didn’t take long to notice the pile of spare large tires. “Oh, I see the spares. I’ll go grab another one.”

“Jess, wait, I’ll help out, those things are heavy.”

“It’s just a tire. It’s cool, I’ve got it.” Jessica reached up and started getting one off the stack. The top tire started tipping over, but was hard to move. “Wow I didn’t think these would be so hard to move.”

Amber started jogging over, “Yeah that’s why you should wait for-”

*THUNK*
“OOOF”

Jessica got the tire loose, and immediately experienced just how heavy it was. She tried to hold it up, but felt her knees buckle as her butt was compressed against the floor. Jessica muttered “Whoa! I guess it is that heavy!” as her body slowly crumpled, fighting the weight squishing her as she was spread onto the floor. Her chest and tummy were being forced into free space as she was mercilessly flattened. Jessica inevitably lost her fight with the tire, succumbing to becoming a pancake on the floor.

The tire immediately rolled off its first victim and rolled towards Amber, who was still running towards Jessica. The color drained from her face as she realized her fate “Oh no.”

Amber turned and tried to run away from the tire, looking for a place she could dive to the side, but she was already too close to the monstrous tire. It bumped into her back and threw her to the floor, sealing her fate.

“OOF!”
*SQUIIIIIIIIIIIISH*

The tire caught Amber’s feet and squished them to the floor. It started rolling up Amber’s legs , flattening them as it went, but also pushing more and more mass up her backside. As a result, the Amber sticker on the floor was getting wider and longer as the tire was flattening her.

It also meant her butt was getting bigger.

*SQUIIIIIIIIIIIISH*
“AAAAAAAAAAH!”

Amber’s eyes opened wide as her enlarged rear end got smooshed to the floor, getting smeared on the floor almost as wide as the tire. Not only was the feeling exhilarating, but mass was now being shifted to the next available space. Her boobs filled up and forced her up off the ground, into the relentless tire.

*SQUIIIIIIIIIIIISH*
“OOooooooooOOOOOOOH!!!”

Amber’s breasts got flattened into 2 extra large pancakes, the edges still retaining some depth since they actually grew wider than the tire.

When the tire was done with Amber, she was stretched to 10 feet long, with most of her body smeared across the tire’s 4 foot path with tire treads. Her hands were still in three dimensions, spread outside the tire’s width, but only able to twitch uselessly at the end of flattened arms.

The tire itself rolled across the room and fell over near a wall without doing any more damage.

Amber took a mental note to try this again later with Scarlett, always regretting when fun things happened while she was at work and she couldn’t truly enjoy them.

Jessica broke the silence, “Oooh...I guess we should get up?”

“I don’t wanna.” Amber replied, still reeling from the experience. “That thing gives good back rubs.”

“Hey, can you two keep it down over there?” Scarlett yelled from across the room, “I think I almost have this fixed!”

Both girls sighed and started peeling themselves off the floor.

* * *

Amber was finishing applying wax the hood of a yellow car. She looked at her reflection and brushed some stray hairs aside. “There we go. All done here.”

She looked around. Jessica was off somewhere getting *smaller* new tires for some of the cars. “Alright, as long as I’m waiting, I might as well check on the fluids.” Amber lifted up the hood and started investigating the interior.

“LOOK OUT AMBER COMING THROUGH!” Jessica came running through holding a pile of tires, blocking her vision. As usual, she wasn’t really looking where she was going.

*BOING*
“WHAAAA!”
*SLAM*

“Amber? Was that you?” Jessica got the tires to their destination and looked back to where she thought she heard Amber. She could swear she bumped into something too, but there was nothing near the shiny yellow car.

“Well, if everyone else is relaxing...” Jessica looked at Scarlett. She was still lost in work under her red car across the room. With Scarlett distracted, Jessica quietly slipped inside.

Meanwhile, under the hood, Jessica’s charge pushed Amber inside while knocking the hood down. Amber’s body was jammed into a fluid tank up to her hips, and it was *tight* in there. She could see a little outside the tank, since her face was compressed against the side, and her hands on either side had no room to push in.

“RRRRRRRG...gotta...push...out.”

*VRRRRRMMMMM*

“Uuh ooooh...” Amber started kicking to free herself faster.

Jessica was leaning back in the leather seats for a well deserved break. “Mmmmmm, listen to that engine purr. Break time!” She leaned back, and turned on the radio.

Amber still couldn’t get much movement. She didn’t want to kick the hood too hard and dent it, so she focused on pushing her head out. She pushed and pushed, and felt some movement from her hands and arms. She managed to straighten her arms!

Which made her wonder, why didn’t the rest of her budge at all?

“Gaaaah come on body work!” She pulled back and tried to push again. Her shoulders were moving and the engine heat was making her build up a sweat, but it actually felt like more of her was getting sucked in instead of pushed out. When she tried to turn her head up and felt her eyes float apart, she figured it out.

“Oh...the engine heat.”

Above the tank, Amber saw her legs drooping like melting candles. A decent amount of her butt was a pile of goo on top of the container, and was dripping into it. The more Amber turned her head to look around to look for a way out, the more she felt herself getting mixed up.

Amber eventually closed her eyes. “Damn it Jess...I just cleaned this thing too.” before completely collapsing into a yellow and peach puddle inside the tank, bubbling from the heat.

Jessica was half asleep inside the car. Sleep wasn’t her plan, but the radio was playing something relaxing.

A loud commercial woke her up. “AH!” Jessica woke with a start, and kicked one of the switches near the steering wheel.

*FWSSSSSHHHHHH*

Thick goopy yellow windshield wiper fluid sprayed onto the car. “Ack! What the hell did Amber do to this thing for tha-...oh wait are those her eyes?”

Amber’s green eyes were scattered on the windshield, staring angry at Jessica.

Jessica laughed, “Hah! So that’s where you went. Hang on, let me get out and fix you up.”

Amber bubbled in annoyance, while she waited for more of her body to spray out.

* * *

Amber was flushing the wiper fluid tank out to make sure she collected all of herself. It was fun to see Jessica have fun with all the cars, but she was going to have to do something interesting to get back at Jessica after today.

Jessica’s cheerful voice broke her train of thought. “Hey Amber, lookie what I found!”

Amber looked up and saw Jessica wheeling in a pair of air compressors. “Really? After everything else today you want another inflation contest?”

“Oh lighten up Amber. We’re almost done with everything, why not have a little fun? Besides, you know Scarlett will have fun watching you blow up.”

Amber felt herself blush, but she had to stay on point. “That’s assuming you don’t go to pieces first.” It was a bluff, she knew Jessica had more capacity.

She also knew Jessica was right about Scarlett loving it. She grabbed a hose and yelled across the room, “Hey Scarlett, you there hon? We’re done cleaning. Wanna see something fun?”

Scarlett’s voice called quietly from the corner, clearly still muffled from being under her car, “Okay! I’ll be there in a minute babe!”

Jessica grinned and turned on the air, “Oh she’ll get here soon enough. Shall we?”

“Alright, let’s go!”

Amber and Jessica both jammed their hoses into their mouths and immediately felt air rushing in. Amber’s slender frame started expanding first, her modest curves growing into an hourglass shape.  She could see Jessica was growing too, but from past experience she knew Jessica’s capacity was immense.

Amber felt her clothes getting smaller. She was starting to spill out of them, her breasts unable to be contained within her tank top. The elastic was helping her shorts contain her growing rear a little better, but her butt was inflating out past the hem line.

Even if this was a fools errand, it did feel really good to blow off some steam and get bigger. Jessica would win, she just hoped Scarlett looked over in time.

*HIIIISSSSSS*

Jessica already knew from experience not to focus against Amber. She might be small, but Amber’s fierce will to win would keep her intact well after most competitors would burst. She made that mistake once, lost a bet, and spent the night transformed for Amber. Never again.

Jessica was snapped out of her thoughts by her pants pressing into her hips. She looked down and saw her own curves. Her butt rapidly approaching beanbag chair sizes, and her boobs weren’t much smaller. Jessica reveled in the feeling of her breasts swelling up a few sizes, and started rubbing her tummy as it peeked out under her shirt. She wanted to fight the feelings of pleasure from her expanding body, remembering her goal was to get bigger than Amber, but damn this felt good.

*HIIIISSSSSS*
*SNAP*
*BOOOOIIING*

Amber’s shorts gave up, and snapping and flying across the room, exposing her purple panties. She felt release as her butt forced its way to freedom, sending a shiver down her spine as it immediately doubled in size. She could feel herself starting to go spherical, although it was take a while before her 5 foot breasts would get absorbed into it. She could see them pretty well out the sides of her tank top, and they were still growing.

The sound of stiffening rubber filled her ears. Her limbs were starting to stiffen into a splayed position, costing her precious mobility. She needed to focus on keeping her shape just a little longer if she wanted to outgrow Jessica, or at least do anything fun.

*HIIIISSSSSS*

Jessica was still getting bigger and loving it. She allowed herself to smile. She could see Amber already outgrowing her clothes, approaching her capacity. Jessica herself was billowing out past 15 feet across, and struggling to see over over inflated breasts. She knew she was in better shape than Amber, but it was getting harder to focus on staying in shape over the pleasure of blowing up.

“Mmmmmm,” She moaned as her butt lifted off the ground, her legs stiffening beneath her as air was mercilessly pumped into her.

*RIIIIP*
*BYYOOOOOINNG*

“Oooooh-OOOOH!” she moaned louder as her clothes were torn to scraps. Jessica’s body, now free from its constraints, billowed out to 25 feet across. Not even close to her capacity, her body was still roughly human shaped, a fact she took advantage of to tease Amber. “Hey Aaaaambeeeeeer,” she said seductively, the words mangled by the hose, “Wanna play?”

*HIIIISSSSSS*

Amber was barely up to 20 feet, and she was struggling to hold more. She was barely mobile when Jessica’s clothes ripped off, and her beautiful breasts sprung into Amber’s face.

“Whoooooa!”
*THUMP!*THUMP!*

Normally a welcome turn on, Jessica’s boobs made Amber lose enough focus that her legs got absorbed by her expanding butt. Now essentially a punch doll, Amber didn’t have much hope of moving. Worse, her inflating body was starting to become transparent. She was getting big enough that her clothes and features appeared to be painted on her skin. She could hold on a little longer, but she didn’t stand a chance.

She felt Jessica’s nipple tickling her. “Oooooooh heehee stop that! Jess!  No fair!” Amber looked over and saw Scarlett still oblivious to their contest, cleaning something off her car. Amber at least wanted her girlfriend to see the end. If she was going to lose anyway...

Amber made her body lean over and move through sheer force of will. Part of bring the Dust Bunny’s most athletic member meant knowing how to move in all shapes. She got her fingers around a screwdriver left out near the last car she was tuning.

“Hey Jessica, I give up. Let me help you deflate.”

Jessica broke out of her ecstasy enough to see Amber balancing on her exercise ball of a lower half, leaning back and poised to spike her enlarged bosom. Jessica had no desire to fight this ending, and instead let her body expand faster, creaking out past 30 feet and bumping into the ceiling. “Aaaaw yeeeeEEESS!” She angled herself to knock Amber’s butt back, speeding up her overhead strike.

*POKE*
“AAAAAAAAAAAAAAAAAAAAAAAAH!!!”
*BOOOOOOOM*

Scraps of dark skin and purple hair flew around, knocking Amber backwards. It was also enough to finally get Scarlett’s attention, having missed the entire affair to this point. Scarlett turned, looked at Amber, and immediately regretted missing it.

Amber’s face was clenched trying to hold herself together, but her arms were quickly being absorbed into the rest of her spherical body. The sound of creaking rubber echoed through the garage as Amber bumped against the ceiling, her everything looking ridiculous, bulging out to handle the pressure.

“Hey Ambe-oooh my...” Scarlett paused to catch her breath, staring at her beautiful girlfriend. “Should I be worried that I can see through you?”

Amber was at her limit. “OOOOOOOOOOOOOH YEEEEEEEEEEEEAAAAAAAAAAH!”

*BANG!*

Amber’s body finally gave out. Scraps of Amber’s yellow shirt and light skin scattered through the garage. The piece with Amber’s face landed in Scarlett’s hands.

She blinked several times, still not looking like she was all there. “Wha...oh, hey, sorry babe. I guess Jess and I got carried away?”

Scarlett blushed and put down the tools for her car. “Next time hon, tell me you’re starting so I can watch.” She gave Amber a kiss, and the couple laughed.

Amber eventually asked “Hey, where did the rest of me go?”

Jessica’s voice answered from across the room, “Hey you two, little help? I think my butt is caught in the window!”

All three kept laughing as Scarlett started collected the pieces her friends.

* * *

Amber’s voice came muffled from inside the steering wheel. “When I said put me back together, this isn’t what I meant.”

Scarlett smiled from the driver’s seat of her red convertible. “Well, you always said you wanted to help with the car, it seemed like a good time.” She buckled her seat belt, “And as the winner, it’s only fair that Jessica gets a ride in the car on the track. You ready Jess?”

“Yeah, thanks for patching me up.” Jessica was back in her clothes in the passenger seat, ready to go. “How come you never mentioned the car before?”

“I dunno, it never came up. Hang on, this thing goes fast!”

Jessica smiled, “This should be fun.”

Scarlett started her convertible and left the garage faster than Jess expected. “Hey, this already goes pretty fast. What’s the most you’ve clocked it at.”

A muffled “Oh no” came from the steering wheel.

Scarlett maneuvered the car around the back of the property to the private track while they talked. It was pretty plain, just a large oval without other curves. “I think I’ve gotten this thing over 300 MPH. Wanna see?”

Amber’s voice said “No!”

Jessica said “Oh hell yeah!”

Once Scarlett was on the track proper, she floored it.

*VRRRRRROOOOOOOOOOOM*

Scarlett was grinning, leaning into the wind as it blew her hair backwards. “I’ve been working on this for a few years, I think I’ve almost got it where I want it. I’m just glad my Uncle lets me keep it here!”

The air pressure was flattening Jessica’s face against the headrest, her cheeks and eyelids flapping wildly in the wind. She was loving it, even as she fought to speak. “Cooooooool!”

Amber was still focused on driving, looking quite relaxed behind the wheel. “Actually, working on this helped give me the idea to do cleaning and stuff. Figured I could work out the other machines too. You’ve seen how that usually works out.”

Jessica was spreading out against the back of her seat. She was as wide as the chair now, slowly going from being in the passenger seat to being the cover for it. The pressure was creating visible waves as the thicker parts of body rippled out.

She wanted to experience this feeling more! “Take it faster!”

“Okay, but not too much, I think this is as fast as it goes.” Scarlett pushed the car all the way.

Jessica went almost completely two dimensional against the chair with the burst of speed. Her eyes, hair, and arms were starting to wrap around her seat, flapping in the wind behind it. She yelled “Woooooo! This is awesome!”

Scarlett saw her passenger’s condition and smiled, “Okay, time for the finish! We’re going to stop now.”

“Whaaaaat?”
*SCREEEEEEEEEEEEAAAACH*
*SPLAT*
*FWOOMF*

Scarlett clearly invested time in the brakes, because the car lost all of its speed in seconds. Jessica was thrown out of her seat forwards, her body mushy enough from the G-Forces to slide through the seat belt. She splattered spectacularly against the windshield, sending bits of brown and purple everywhere, her gooey pancaked butt spread across the window.

Not that Scarlett could see Jess’s butt dripping off the window. Her face was buried in her new air bag, which looked suspiciously like Amber’s tank top. Scarlett was smiling contently, hugging her lover’s inflated bosom.

Amber cried “Oooof! Why do I always have to be the air bag?”

“Because this way I don’t miss you inflating silly!” Scarlett hugged Amber a little tighter, knowing she was probably already planning some kind of revenge for that night.

She was looking forward to it.
