Summer had begun. A heat wave struck the Dust Bunnies’ fair city, and that meant time to hang out by the pool.

After a morning of swimming, the four started relaxing. Amber and Zoe stayed out in the sun to work on tans, while Jess and Scarlett went inside to work on lunch. They were working on simple sandwiches for lunch, and eventually mixing drinks.

Scarlett checked her phone between sandwiches while Jess was debating mixers at the fridge. “Thanks for helping with lunch, but you can slow down a little.”

Jess closed the fridge, holding a few strange colored bottles. “No problem. Honestly I’m surprised you’re still solid.”

Scarlett roller her eyes and put down the utensils. “Oh please...” She paused, immediately sweating huge red drops of herself to the floor. “It’s way too hot outside for that. Mmmmmmmmm!!!”

Five seconds later, she completely collapsed into a gooey red puddle, layers of red pudding spreading across the floor, with her face with blue eyes on top. “Doesn’t matter to much me though. I just wanted something to drink before it actually gets too hot to keep myself together.”

Jess shook her head and laughed. “Fair enough, but I’ve got a thought. Have you ever seen Zoe make one of these drinks?”

She put the bottles down, then got a martini mixer out of a drawer and went to work. Scarlett bubbled up from the floor into a red slimegirl and watched her purple haired friend pour some things she recognized, and a few she didn’t. But what peaked her interest most...

“Is the blue one supposed to bubble like that?”

Jess nodded. “Yup. Be careful with that one. Put in too much and it gives the drink away. Not enough and they’ll barely feel it. But if you use just the right amount of grape juice...”

She poured both bottles in at the same time. Scarlett watched it fizz and produce a swarm of blue bubbles foaming just over the edge, but not enough to spill. Jess covered it up, shook it three times, then squeezed it together. The container produced a violent metal clanging noise and looked like someone was trying to fight out from inside. Jess struggled to contain it for 10 full seconds with her hair getting blown back, dents pushing out from inside before the shaker forced itself back to normal, but it soon calmed down.

“Whew...it’s done. Now, we have to be careful with this.” Jess slowly put down the mixer and grabbed a tray and 2 margarita glasses. She treated the concoction like hazardous materials, holding it at arms length to open it.

Scarlett leaned in for a better look, reaching a long red finger towards it. “What’s that thing do anyway? You act like that drink is going to-”

Jess opened it, and a gust of wind blasted out. Jess’s long purple locks were blown straight back again. Scarlett, who never truly solidified, was pushed back drop by drop, red goo splattering everywhere on the back wall.

SPLOOOOOSH

Jess smiled at the splat, then carefully poured two drinks. “Don’t touch it hon. At least not until our friends outside get to have some.”

Scarlett grew arms and glooped herself off the wall, pushing until her sexy figure emerged from the splat. “Aaaw, can I just have a taste?”

Jess looked at the glasses and, satisfied they were full, looked inside the shaker with one eye and offered it to Scarlett. “Here. But stand over there when you try it.”

Scarlett yoinked it and slid to the door on her goo pillar legs. Her huge smile faded to a frown when she saw the meager amount remaining. “That’s it?”

Jess nodded. “In that form, that’s all you need anyway.”

Scarlett shrugged and downed what little there was. She smacked her lips. “Hmm...I taste the grape, and it’s sweet and fruity, but what’s the extra...Ooo!”

HIIIIIIIIIISSSS!

Scarlett’s breasts and belly filled with air from the fizzy drink, turning her into a huge red balloon in almost no time. Her limbs puffed up and got sucked into her body, her form grew transparent, and she started trembling from the pressure.

“Oooooh that’s good. But...I haven’t...figured out...slime...capacity...-AYEEEEEEE!”

POP

SPLOOOOOOOOOOSH

She splattered everywhere, covering Jess’s smiling face with red slime.

“Told ya it was powerful stuff.” She licked the goo off her face, smacking her lips. “Oooo, cinnamon.”

* * *

Scarlett (once again human) and Jess were very bad at being quiet - they were giggling wildly as they walked outside. They walked out to their sunbathing friends with a tray holding four blue drinks, two of them with trinkets to know which was which.

They walked into the summer heat from the safety of the house to the side of the pool. Two long lounge chairs held what remained of Amber and Zoe, long since melted into long blobs bubbling away in the sun.  One was mostly yellow with light fleshy goop, the other jet black mixed with dark tan, each with sunglasses floating on top. They were mostly in their seats, though much of them had spilled to the ground.

Scarlett looked at Jess, wiping her melting hair out of her eyes. “Think they’re awake?”

Jess shook her head. “There’s no way. Neither of them are you, and Zoe almost as a policy never sunbathes while solid. Just take one for Amber and have her drink up.”

They nodded, splitting the drinks, and went about their plan.

Scarlett sat down on Amber’s gooey puddle with a SQUISH!, putting Amber’s drink down on a patio table. “Time to get up babe,” She swirled a finger in Amber goo, “before I have a banana shake.”

Yellow bubbles danced across Amber’s surface. Seconds later her body flowed back together, arms reforming from the puddles like a waterfall in reverse. Her yellow slime rose like soft dough around Scarlett, forming the leggy blond stretching her arms into the air with a loud yawn.

“AAAAAAAAWWWW!!! Hi babe. Don’t even try to drink me in the sun. Remember the last time I melted while huge and-...babe?”

Scarlett was sweating red bullets just thinking about it. “And I got so big, I couldn’t finish...gaaaah wait!”

She shook her head as she almost melted into a red slime, scattering drops but resuming human form. “I could do it if we tried again, I swear!”

Amber shared a laugh with her at the thought. They soon heard Zoe laughing with Jess nearby too. “Darling, you couldn’t stay solid drinking a half-gallon of banana blond let alone a bath tub.”

“Heeeeey!!!” Scarlett protested.

Amber got up, holding her arms between the two to break up the scuffle. “Hey now, this is a pool day. Let’s just calm down and... oh cool, is this for me?”

Scarlett nodded absent mindedly, staring down Zoe. “Yeah, but I might still ask you to melt into the pool again later.”

This time Jess laughed. “I’d pay to see you get that big. There’s no way.”

Amber could swear there was a little extra to Jess’s comeback. That and her eyes quickly looking at the drink. But she didn’t dwell on it.

“Whatever. Guess it’s time for giant swim practice after this.”

GULP

Amber downed the glass in a single gulp. She paused to consider the fruity drink, swirling the empty glass in her hand. “I can’t put my finger on it. It’s kinda fruity...kinda fizzy... and Cinnamon? Scarlett?”

The blond’s head snapped towards the melty one. “Why does this taste like-”

HIIIIIISSSSSSSSSS

Amber’s body puffed up, going from her sleek trim muscled self to puffy ballooned body in seconds. Scarlett was pushed off her leg by the expanding force, bloating Amber’s joints enough to force her into a standing position.

The red head smiled back at her favorite balloon. “Because when I’m all melty I pop fast. Did the cinnamon help the flavor?”

Amber sighed. “Actually, yeah. It really made the-HEY WAIT-ooooooooooooooohhhH!!!”

HIIIIIIIIIIIIIIIIISS

FWOOOOOOOOOOOOOOMP

Mid sentence Amber’s breasts started growing. Air filled them, pushing them into into the air. They swelled past watermelon size into couch cushion territory, with thick stiff nipples pressing through her bathing suit.

“Ooooooooooooh this feels goooooood-”

HIIIIIIIIIIISS

BWOOOOOOOOOOOOOOMP

Amber’s butt filled next. Her cheeks rippled out like the balloon she was, surging out to an eight feet wide ass. Sun tanned flesh desperately tried to escape the bottom of her swimsuit, absorbing her legs into them and forcing Amber off the ground.

Scarlett was already starting to melt again, watching Amber get huge, sinking into a red puddle in her blue suit.

“Oooh no fair! This is making me huge and...and...-”

BWOOOOOOOOOOOOOOOOOOOOOMP

CREEEEEEEEEAK

Amber’s belly was next. Her time as a ridiculous hourglass ended with her tummy billowing out to match her assets. Not that they didn’t grow even more too.

Amber’s whole body was going spherical. Her arms swelled larger until her shoulders arms snapped into her spherical shape with rubber squeaks. Her neck got pulled in, until her face was stretched across her surface. The only sign the giant yellow sphere was human was the slight extra domes of her massive breasts, and the drawings of hands and feet on the sides.

And the intense blush on her face, still visible even when she turned dangerously transparent. “Ooooh god this presuuuuuuuuuuure!!! This feels GREAT!”

HIISSSSSSSSSSSS

CREEEEEEEEEEEEEEEEEAK

*FWOOMP*FWOOMP*FWOOMP*FWOOMP*FWOOMP*FWOOMP*

A loud rubbery creak and a high pitched whistle echoed out of Amber and a smile stretched across her face. Her hands and hair and eyes bloated off her sphere. She was trembling from being too full.

“As soon as I’m back together I’m gonna-”

BOOOOOOOOOOOOOOOOOOOOOOM

At the beautiful size of 20 feet, Amber popped. Scraps of yellow giantess fluttered around, eventually landing near her chair in a messy yellow pile. Scarlett was splattered by the blast, as if someone threw red paint on the patio.

Jess still stood there, hair blown back yet again. Zoe stared with her mouth hanging open, lifting her sunglasses for a better look at what remained of Amber.

She looked to Jess, very excited. “PLEASE tell me my drink does that too!”

Jess nodded slowly. “Of course it does! What kinda woman do you think you’re sleeping with?”

Zoe snatched the glass, downed it, then kissed Jess’s cheek. 

HIIIIIIIIIIIIISS

Within seconds her big tan tits rumbled and inflated against her already too small black bikini. She opened her arms and let the rest of her body fill up, easily snapping off her bikini. She blew past 10 feet wide as a naked tan sphere for Jess to lower her glasses and ogle.

“OOOOOOOOOOOOH Yeah...This is why I love you babe.”

CRREEEEEEEEEEEEEEAK

BOOOOOOOOOOOOM
