There was a heat wave.

A really big heat wave.

Most people knew to stay inside on days like this, lest they find out how effective the centrifuges at the end of the sewers were. Certainly Zoe and Jess were staying inside today. Scarlett did too, not that melting seemed to slow her down anymore.

The weather was not going to stop Amber from taking a morning jog. She finished her run, and took her phone out to log it, even if it was trying to slip through her hand while she got her keys out. “There, 180 of 180 days this year with a run. Two miles is kinda low, but it’s hot out here. Not too hot for me though! That’ll show ‘em. No weather’s too hot for me and-”

PLOP

She looked behind her. A small puddle of yellow goo sat on the sidewalk. “And that’s my hair melting...time to get inside.”

Amber pushed with her right leg to pick up the pace, and heard a SMOOSH from her ankle. She could feel her calf liquefying and spreading into layers of goo on the concrete. “Shit! Go go go go…”

PEEEEEEL

The bottom of her shoe was sticking to the ground now, strands stretching from sidewalk to foot. Her gooped leg was uneven on the ground too, throwing off her balance. Still, she made it to the door.

She kept her hand solid through sheer force of will when she jammed it into her pouch to get her keys. Her fingers wanted to gel together in the sweet heat. She kept them solid, felt them sinking too far into her hips. “Come on keys, open the door! My shorts aren’t supposed to sweat pink and I shouldn’t be sinking like this!”

Indeed she was sinking to the ground. Amber looked down and immediately regretted it. Her butt was sliding down her thighs, absorbing all her lower body into a giant pink blob. Flesh and yellow colored sweat flowed down her abs, signaling her core muscles melting down to mush. Her stomach looked less like a 6 pack and more like peach water balloons sliding around. Her beasts were two floating scoops of banana ice cream in her yellow shirt now, most of the boob flesh melted away and suspended in a gooey soup in her sports bra.

More hair dripped into her face and she knew she was cooked. She turned the key, feeling her wrist sliding around on her arm. “Come oooon!!!”

CLICK

The door opened.

“Yes! Scarlett?! Anyone?! I think I need-”

SPLOOOOOOOOOOOOOOOOOSH

Amber could feel the air conditioner, but her body was too much of a slimey mess. The moment she tried to step in, her body tilted forwards. The pink goo that used to be her shorts floated most of her in like a slime girl riding a pillar, but her upper body fell forward. That push was enough for everything in her shirt to spill out, crashing to the floor in a wave of yellow paint. Amber tried to reach for anything sensitive to make the most of it, knowing she was as good as goop, but she didn’t have anything solid left to fondle. Anything remotely intact splattered apart, spreading her hair and eyes across her wide puddle. Her colors mixed together, settling on a pinkish-yellow tone, bubbling on the floor from absorbing too much heat.

Heh...at least I made it inside. That counts as not melting during the run! At least I can just relax and feel...myself...float away...aaaaaaaaaaahh...

The door closed over her, only getting small splashes of yellow on it. Amber fell asleep in her liquid state, too exhausted by the run and enamored by the love of melting to care about getting up.

* * *

Jess knew she heard the door open a few minutes ago. It was one of her quiet days to work through her next game project, so she didn’t jump into action.

Once she hit a good break point though, she realized she hadn’t heard anything since that tell tale sploosh. She put her book down to get up, muttering “Guess I better check on her…”

She got up from her desk, wearing a green tank and short denim shorts in the heat rather than her usual jeans. When she arrived at the door she found Amber still bubbling on the floor. “Well then. Guess it was too hot even for you miss I-own-fire?”

She gave Amber a moment to respond, but by then Amber had completely zoned out.

“Guess you’re stuck that way for a bit. Now what to do with you...I could pour you into the game table mold and carve a miniatures grid into you...I could test some new figurine molds. Oh I know!”

Jess twisted and yelled back into the house. “Hey Zoe!”

“Yeah babe?”

“You have that water tank ready? Gotta stay hydrated on a hot day like-”

“You got it babe! You want me to get all big for you now or wait a minute?”

Jess laughed. “Give us a minute. Am I really that obvious?”

“Babe you’ve tried that every day of this heat wave. Just ask, you know I love it too.”

Jess smiled and licked her lips. “That’s why I love ya! Now…”

She turned back to the bubbling mess of yellow goop at her feet. “Time to mix up with you. I’m going to need your help working Zoe over, and I know just the thing.”

Jess kicked off her indoor sandals and tip toed through the Amber goo. She curled her toes at the far side of the puddle when she reached the dough, not passing up the chance to really feel Amber’s warm goo rub against her.

She took a deep breath and grabbed the door knob. “Alright, let’s hope it’s as hot out as your puddle says it is.”

CREAAAAAAK

“Aaaaaaaaaaaaaaaaaahhh yeah…”

Heat from the outdoors washed over Jess with a fiery orange light. Her entire form wavered in the heat, losing solidity and sweating colorful drops to the floor. Denim blue and green shirt dripped into rivulets of color running down her deep brown skin. Her legs sank into layers of fleshy puddles, dragging her belly down with her hips as her torso melted across them.

She managed to swing the door closed before her arm dripped apart, splatting to the floor in a brown splash. Her hugged her chest with the other, squeezing her gooey green breasts together until they spilled through her arm, topping the growing puddle with a layer of green swirled with brown. Her body swirled like soft serve as she sank, spreading on top her liquefied remains. Her head full of purple hair was the last bit of her solid, spreading across the surface of their combined puddle on the floor.

“Yeah...that might be too hot...but it felt GREAT. Let’s wake you up and mess with Zoe… BLUB”

Jess’s face spilled on the surface, then faded into the rest. Soon her whole puddle shifted to a purple shade of goo, mixing into Amber’s yellow. Two ladies worth of melted goo mixed together, tendrils reaching into the air, seeking a shape and figuring out who went where.

Eventually the puddle coalesced around two yellow tendrils. They morphed into arms with purple wrist bands and pushed on the floor just outside the puddle to pull the rest of her out. A yellow purple mash-up grew out of the goop, with a wild purple ponytail on a yellow head. Her massive yellow tits were barely contained by a hot purple sports bra, shorter than either of their tank tops, and her dump truck ass was held up by capris, though she currently had bare feet.

She shook herself off, getting more human colors while some last drops of yellow and purple slime scattered around her. She looked herself over, lime green top on magenta capris with skin somewhere between the two that made her.

You okay Amber?

Uuugh...thanks? I think? Why...are we...

The fusion walked briskly through the hall while Amber and Jess thought to each other. They opened the door to Zoe’s room and saw her already with a water hose in her mouth. Her body was already bloating all over, doubled in size towering over her new playmates.

“You two took too long and I got thirsty. Better act fact or I might drink you next.”

Amber felt herself making the fusion nod.

Aaaah...I see.

Yeah, I need your help handling Zoe. Figured you wouldn’t mind a second work out today.

Just make sure the air conditioner’s on. I can make us big enough to squish her.
