Scarlett rolled over, not wanting to get out of bed. She stretched her legs and kept her eyes closed, trying to ignore the sunlight filtering through shades and get back to sleep.

*Aaaah there are my legs. Now I know I'm waking up, I'm pretty sure I was a puddle when I fell asleep...*

She took a deep breath, relaxing and enjoying being human. She let her hands wander to where Amber should have been in the bed, wondering if she could catch Amber literally napping...

Nothing.

She must have been moving enough for Amber to notice though. "Rise and shine sleepyhead."

Scarlett sighed, but didn't open her eyes. "Already? Can't I stay asleep?"

"Not today babe. I've got a race in an hour, I need to keep moving. Were you coming with me today?"

Scarlett felt a warm tingle fluttering within her chest. She remembered today's race was just another 5K, not a special event or anything that would take a really long time for Amber to finish. That left only one reason Amber would ask if she was tagging along.

She finally opened her eyes. She found Amber standing near the bathroom door. Her hair was wet, and drops of water still sparkled all over her fit and sexy body. Her pink towel was thrown over one shoulder, doing absolutely nothing to cover her perky breasts, and she wore nothing else but her pink mesh running panties.

That got Scarlett to sit up, propping herself up on her elbows. She wanted to take in Amber's glory before what happened next.

"Mmmm, you look ready to me. Did you want pancakes for breakfast?"

Amber licked her lips. "You know it!"

Scarlett loved it when Amber did this. She didn't always do this before a race, but Scarlett loved it when Amber wanted to work herself up. Since they learned more about Amber's growth being more than just zany adrenaline fueled giant smashes, Amber was practicing making specific parts of her bigger. She could still only get so big for so long if it was only a part of her, whether it was punching down a wall, or in this case...

Making her ass huge.

Amber leaped into the air, and directed her growth to the butt. Her supple cheeks jiggled larger and larger, doubling and tripling in size. Even though her clothes grew too, her underwear looked increasingly like a thong between her big bubble butt.

Scarlett smiled and opened her arms, gladly accepting her fate.

*SQUIIIIIIIIIISH*

Scarlett felt her head collapse under the crushing force of Amber's big butt. Her chin was buried between her breasts, instantly spreading her head against her shoulders. Then she felt her body fold into itself, collapsing like an accordion and sending a tingle through her whole body. Her own butt spread pleasantly on the bed, forcing her thighs flatter on the bed, fusing her entire being into a fleshy pancake under her lover.

*WHAM*

* * *

Amber didn't shrink back to normal size immediately, instead wiggling her hips and giving her new seat cushion something like a lap dance. "Oh Scarlett, what ARE we going to do with a squishy lazy girl like you."

She finally shrank her butt back to normal, pressing her soft flesh against Scarlett as she did. Strands of Scarlett's face and splattered red hair stuck to it as it shrank, slightly pulverized and slightly melty from her beloved's touch.

Scarlett herself was a 5 foot diameter mess. A huge goofy grin was literally spread across her blushing cheeks. Her butt and boobs both extended past the edges of a circular shape, likely smeared further by Amber's added massage, and Scarlett's own practice trying to be like Zoe.

Amber flicked some stray goop into Scarlett's pancaked shape on the bed and grinned. It didn't matter how many times she obliterated Scarlett's body in bed, the red head was still beautiful to her. Plus she couldn't complain about Scarlett's curvy results. "I guess I need to get you back into a reasonable shape?"

Scarlett gleefully closed her eyes. "Yes please!"

Amber peeled Scarlett off the bed, whipping her floppy body in the air enough for a satisfying snap, but not enough to restore her. She put her flat girlfriend back on the bed, and placed her palms on Scarlett's beautifully wide saucered breasts.

Amber leaned in, and kissed Scarlett. It started normal enough, at least for her three dimensional lips against a flat doughy Scarlett. She flexed her fingers, making small indents while gently groping Scarlett's flat form. For a short time, it was a simple make out session, the two lovers simply enjoying the moment.

Then Amber took a deep breath, and blew into Scarlett.

*HSSSSSSSSSSSS*

It took Scarlett a moment to realize something was off. She could feel the air flowing through her, but most of her body wasn't expanding. Not that she was complaining, because something felt great. Her eyes wandered her flat face, until she saw the big balloons behind her.

Not that she could say much with Amber blowing into her. "Mmmm!  Mmmmmph!"

Amber broke the lip lock enough to place a finger on the flattened one's lips. "Hush my pancake. I'm just giving  you extra cushioning before we continue."

Scarlett watched her butt balloon well past generous proportions while the rest of her remained flat. She raised an eyebrow, then looked back to Amber's hands and smiled mischievously. "Oh, so you weren't just feeling me u-OOOOOOOH Yeah!"

Amber flexed her fingers again, winning a satisfied moan from Scarlett. She mock shrugged. "You caught me. You know I like the booty."

"Okay, but-Mmmmmmmmm yes!"
*HSSSSSSSSSSSSSS*

Amber licked Scarlett's lips and went back to work, blowing up Scarlett's butt even more while keeping the rest of her pressed flat. Only once Scarlett's butt consisted of two very inflated spheres did she break off the kiss.

"Okay babe, I think you can help me with a few stretches before my race now."

Scarlett was breathing heavily. Part of her wanted to melt right then and there, but her desire to be molded by Amber's hands kept her solid. "Oh? How can I...*gasp*...help?"

Amber gave Scarlett one more peck on the cheek, and ran her hands along her squished bosom, before tossing her floppy body into a heap near her butt.

"Ooof! Just tossing me into a heap? Surely you're doing something more than-OH!"

*SQUIIIIIIISH*

Amber grabbed both sides of Scarlett's inflated ass, and folded it in half around the rest of Scarlett. Between Amber's speed, and Scarlett already being on the verge of losing solidity, Scarlett was splattered by her own butt. Globs of blue and red goop ran down the sides of her inflated cheeks, making both ladies very happy.

Amber's new balloon toy shouted in her hands. "Ooooh! Again!"

Amber herself was starting to feel warmth welling up inside. She took deep breaths, pacing herself so she wouldn't have a full meltdown herself before the race.

She ran a finger through Scarlett, liking some of the goop to enjoy Scarlett's cinnamon flavor. "Silly splatter, puddles don't get a vote this morning."

"Oh?" Scarlett's voice was more excited than worried.

Amber pushed the inflated orbs together, making a rubber squeaky sound, then pulled them far apart, sounding a very out of tune note.

*VVVVVVVVVVVVVVVV*

"Hah! I can't believe that worked!"

Despite being gooped moments earlier, the pressure gave Scarlett a modicum of solidity. Still, caught between two large halves of herself, Scarlett's body tried to keep them connected, and reflexively molding into a familiar crinkled musical instrument.

Scarlett's smiling face looked up from the mostly blue bellows. "Hahaha! You turned me into a butt accordion?!"

Amber laughed, and continued slamming Scarlett's butt together. "Yup!"

"WHEEEEEEEEE!!!"

* * *

Amber played with Scarlett for minutes, stretching her apart and slamming her together again. Each one got a little more of a wet squish sound from the accordion, as Scarlett was clearly enjoying being Amber's plaything.

But Amber knew she had a race. And she needed one more extra special thing before she left. "Okay babe. This is fun, but I do need to get to the race."

Scarlett pouted from her bellows, still opening and closing. "Aaaaw. But we were just starting to have fun."

Amber put one end of Scarlett down on the bed. "Don't worry, I'm not done with you yet. I want your good luck touch today."

That lit of Scarlett's face, making her grin cheek to cheek. "You mean?!"

"Yup!"
*SQUIIIIIIIIIIISH*

Amber enlarged her hand so it was as big as the bed, then slammed her hand down on Scarlett. She loved the feeling of Scarlett's squishy if inflated booty trying to retain depth through her fingers, finally accepting its fate to be a floppy sheet of blue and red against the bed.

"Oooooh I love it when you do that."

After one move loving touch, Amber opened her side table and pulled out fabric scissors.  She snipped them twice in the air, and pickled up the floppy sheet of Scarlett.

Scarlett was shaking with anticipation. "Promise me you won't be gentle."

*SNIP*SNIP*
"AAEEEEE!"

Amber grinned at Scarlett's playful scream. Still, she asked before the next section. "You sure? I could-"

Scarlett's response came between short breaths. "Don't stop!"

Amber dug in, quickly slicing Scarlett into sheets of her component colors. Some scraps were so small they had to be mashed into the bigger sheets of herself. Others were perfectly reasonable sizes, but Amber smashed them together anyway just to hear Scarlett coo and moan from being split and squished back together again.

Despite her playing around, there was a purpose to this. Amber eventually crafted Scarlett into two long and narrow strips of red-hair cloth, a long band of blue from her shirt, and a smaller rectangle of peach skin. Using her fingers, she squished the edges together, squeezing them until Scarlett sighed from her segments mushing and recombining.

She held up her creation, looking at the wide peach panel attached to red straps with a wide blue back. "Looks like I've got my lucky supporter. You know, you could still stay home, and I could wear a normal one if you wanted."

Scarlett's blue eyes appeared, opening spaced apart the front. "If you put me through all that and DON'T let me squeeze your boobs all morning, I promise you won't be solid for a week."

Amber smiled, but looked her back in the eyes. "Don't threaten me with a good time. But sure, what if I do wear you?"

Scarlett's eyes had the look of an embarrassed smile, but without the mouth. "Um...you won't be solid only tonight?"

Amber shook her head. "You need to work on your threats babe."

Satisfied Scarlett was pleased, Amber slipped into her favorite blue and red sports bra. She'd found a thicker dark pink tank top to wear over her, since teeeeechnically wearing a friend was against the rules, but nobody every checked.

More importantly, she knew Scarlett really did provide support. The moment the woman's cloth body touched her boobs, she was practically form fitting. Scarlett knew better than to squeeze her to the point of melting mid race, but still stopped her from bouncing all over the place while she ran.

It was a warm hug lasting the whole race, with Scarlett's touch for encouragement. And once they returned home, Scarlett almost always restored herself in some way that squeezed Amber's tired out body like toothpaste, reducing the runner to a messy collection of colorful puddles. That is, assuming Amber wasn't in good enough shape post-race to inflate herself and burst her Scarlett clothes to shreds...

Amber shook her head, snapping out of her lusty day dream. No melting until later! "Okay babe! Let's go win a race."

She felt a warm hug from her clothes in response, squeezing her boobs together almost too much.

Amber sighed. "This is why I love race days."

Scarlett's voice came from her chest. "Love you too babe!"
