Jessica’s head quietly rustled out of the bushes behind the diving board.

*Excellent. They both think I’m helping Zoe with the dishes. Amber’s drifting pretty close to the diving board too. I just need to stay quiet, and then I can have a little fun with her after last time.*

Jessica sprinted across the concrete on bare feet, and made it to the diving board. She hid behind it, peeking and waiting for Amber to float closer. Once she did, Jess jumped towards her, arms and legs stretched out for a belly flop.

“WOOOOOOO!!!”
“What the?!”

*SPLAAAAT!*
*SPLASH!*

Amber sprung up too late. She reflexively raised her arms to defend herself, but Jessica fell too fast. Amber was squished into a large rectangle against her raft, complete with ridges. Her eyes were wide with surprise, slowly looking up at Jessica, wondering what she had planned.

Jessica lay down on top of Amber, idly running a finger along her flat tummy. “Hi Amber! You looked a little lonely. Want to play a little.”

*SHLLLLLRRRRRRRP*

Jess peeled Amber off the raft, being careful not to tear her. Amber had a resigned smile on her flat face. She may be a sheet, but Jessica at least knew how to have fun. “Okay, is this for making you a pool toy? Because you’ve gotta admit that was funny.”

Jess chuckled. “I guess you’re right. But you did look thirsty out here all by yourself. I thought I would get a drink.”

Jessica carried Amber to the side of the pool, where she had a hose with running water ready.

“Drink up!”

Jess put the hose into Amber’s mouth, and turned up the flow. Her flattened body responded immediately, shaking a little and rising up as one big water bed. Jess flipped her into the pool to give her some room to grow, and Amber’s body briefly popped back into her feminine figure, even if it was clearly full of water.

Amber didn’t get to feel normal for long. She kept growing, and she was honestly enjoying it. Her cheeks puffed out as water flowed into her. She grew past eight feet, her boobs growing fuller, spilling out the top of her swimsuit, her belly growing down and touching the bottom of the pool. Her arms were filling with water, rapidly getting absorbed into her expanding body. Soon enough Amber’s butt joined the party, her cheeks expanding towards the other side of the pool, spherical body absorbing her legs as it grew. She groaned as her clothes started creaking, and her cup size kept increasing, reaching impossible sizes, until

*SNAP*
“MMMMMMMMMMMMMM!!!!”

Her bathing suit finally gave out, scraps of it flying everywhere around the pool. Freed from constraints, Amber’s body grew faster, jiggling and wobbling all over  from growth as water continued to fill her. Her butt was big and beautiful, starting to smush and mold itself around the other side of the pool. Her breasts were spreading on the patio poolside, no where left to grow inside the pool.

And she was still growing. Amber wasn’t sure how much more she could take. She started rubbing her butt against the pool wall, getting ready for the exciting conclusion.

Then Jessica turned off the hose and laughed. “Okay, okay, I guess this might be a bit much.”

Amber glared at her, screaming through the hose. “OH COME ON!”

“Now now!” Zoe emerged from the house and walked towards them. “I missed the water bed party last time, and I need to relax after working all afternoon in the kitchen anyway.” She took Jessica’s hand. “Come on, I could use some rest.”

The couple walked on top of Amber, and started rolling around on her back, leaving her in a weird state. “You two know we’re basically waiting for Scarlett to wake up, right?”

Amber heard Zoe’s voice. “Oh, she might be a while.”

Scarlett was staring right at her. Watching her girlfriend blow up to ridiculous proportions, while resting in the hot summer sun, definitely had an effect on Scarlett’s body. There was a growing puddle of melted pale skin under her chair, and Amber could see her dripping through the mesh.

“Hi Amber. You’re look pretty good right now.” Scarlett was hugging herself as her legs soaked through the chair and dripped to the ground. She threw her head back, red hair splattering against her seat, and rolled back and forth from the excitement. She was forcing more of herself through the chair, oozing and flowing into the puddle on the ground, committed to enjoying her melt.

“Oooooh...” Scarlett’s arms went from hugging to sliding off her chest, taking a lot of her chest with them. Her body rippled into a puddle, losing any hint of its shape.

“Aaaaaambeeeeer-blbblb...”

Scarlett was a bubbling mess on the patio. Amber sighed, resigned to being stuck as a waterbed for a little while.

* * *

It took more than a few minutes for Scarlett to get up again. Amber knew Zoe and Jessica stopped moving a few minutes after climbing on top of her, but she could still feel them on her back. She wasn’t sure how solid they were, but they hadn’t rolled off yet.

“You there Scarlett? Babe? I could use a little help here.”

“Ohh...how did I miss this one?”

“I think Jess wanted playful revenge after pool toy experience. Not a big deal, except holy shit I need to do something about these.” Amber wiggled what was left of her hands to point at her overflowing boobs on the patio.

Scarlett was still dripping with beads of her melted self. “Oh...of course...what do you need hon?”

“You either need to get this water out of me, or put more in.”

Scarlett’s eyes went to the hose, then Amber’s breasts, and back again.

She shook her head to regain some composure, and sauntered over to the hose. She turned it back on, put it back in Amber’s mouth, and said “Why not both?”

Amber eagerly accepted the hose, and wobbled as her body filled more. Her anticipation grew as Scarlett walked up to her left breast, and took the huge nipple into her mouth.

She suckled gently, and the floodgates opened.

Amber gasped as Scarlett drew water out of her. It felt great to be growing again, and Scarlett was another welcome sensation. After being teased to this size in the pool so long, this might have been worth the wait.

"MMMMMPH! Careful babe, I've got a lot to give right now."

Scarlett was already getting weighed down by the water. It was rushing into her tummy so fast, she was already scraping the patio. Her boobs were growing too, pulsing with growth and fighting to escape her swimwear. She started teasing them with her free hand, and leaned closer to Amber to keep her mouth around her.

"Ooooooommmmm" Scarlett was completely on her stomach now. Her thighs were expanding, her feet wiggling in the air while she teased Amber. She was a jiggly eight feet across already, but that was nothing compared to Amber in the pool.

She was already filling the pool before Scarlett turned the water back on. As much water as she was pumping into Scarlett, the hose was filling her faster. Amber felt her back swelling up out of the pool. Her butt and boobs were spreading further on the patio in search of room to grow. She knew she was approaching her limit, expanding higher and higher, but she felt something curious on her back.

Zoe and Jess were squeezing her butt.

"OOOOOH!"

Amber's body rippled as her friends had their way with her, and that sent even more water gushing into Scarlett.

"MMMMMFUUUUUUUUUK"

Scarlett grew past fifteen feet in a heart beat. The rubbery sound of her toony body creaking filled the air as her legs and arms were absorbed into her expanding body. She shook as she hit twenty feet, rippling from the pressure inside her. It was too much.

"HOLYSH-"

*SPLLOOOOOOOSH*

Scarlett exploded with a gargantuan splash, scraps pale skin flying everywhere. The blast showered Amber with water, still reveling in her own growth, and only feeling more excited after watching her girlfriend burst.

The explosion forced Amber away from the edge of the pool. When she bounced back against the poolside, too much of her scrunched up and rolled over the edge, and she couldn't take it anymore.

"YEEEEA!"

*SPLOOOOOSH*

Amber went out in an even bigger blast. Water splashed everywhere, and nearby trees bent backwards. The backyard pool was left covered with Amber and Scarlett.

Zoe and Jess were blasted high into the air too, directly above the pool. Jess was laughing, resigned to her fall. Zoe attempted a swan dive.

*WHAAAAM*

Both splattered into puddles of goo matching their colors on the bottom of the pool, each reduced to a smattering of goo several feet across.

It took some time before Zoe and Jess bothered to reform.

"See Jess, that's why you have to be careful with water beds. They're too fragile."

"Sure Zoe, I'm pretty sure I talked you out of popping her at least five times."

Zoe shrugged. "All in good fun."

They climbed out and saw their friends collecting themselves. They both rubbed their heads, slightly embarrassed.

Zoe sighed. "I guess we should help them."

Jessica gathered up some of her friends. "One question though. What are we having for dessert?"
