"Scarlett, I'm home!"

Amber walked into the house, smiling but exhausted after her day at the mountain. She kicked off her shoes and went further inside in search of her melty girlfriend. She finally found her playing video games in their bedroom.

"There you are."

Scarlett paused and put down the controller. "Oh hey! How was it? Did Sonia put you through the proverbial wringer or the actual wringer?"

Amber rolled her eyes. "Mostly proverbial, but there might still be bits of me on the floor."

Scarlett grinned, excited to think about Amber getting squished. "Ooo, you'll have to tell me more later. Did you get her back?"

Amber gave a slow nod. "Oh yeah, I got her a few times. She's still pretty big when she wants to be giant though."

There was a brief silence while each thought about where the conversation was going.

Scarlett picked up her questioning. "Well? Did you learn anything? Are you really some secret super hero giant lady?"

Amber laughed. "I guess so? One, I learned to never wrestle that far above my weight class. Two, giants have super soft and squishy butts."

Scarlett giggled and her eyes lit up at the prospect of hugging a giant Amber's hips soon. "So she sat on you at least once?"

"Sort of. We both got to our place in the mountains and I asked Sonia..."

* * *

"How should we begin?"

Sonia and Amber met at the training mountain. The large room was cleared out after Sonia's adventure with Scarlett a few days earlier, giving the two giants plenty of space to work in the large cavern.

Sonia took a few steps away from Amber, putting a safe growing distance between them. "You know, I haven't thought about that. I've never had to teach someone how to change size before. Certainly not anyone that was as, uh, flexible as you and your friends are in this world."

They started at each other for a moment, while Sonia scratched her chin thoughtfully.

Sonia shrugged. "Why don't you just try it?"

"Okay." Amber closed her fists, and tensed her body like an anime character powering up before a fight.

"Come on body, get bigger!" She paused and crouched even more. "BIIIIIGGEEEEEER!"

Sonia watched, feeling a little nervous and embarrassed. Amber squeezed her fists so hard her knuckles turned white. She was putting a lot of effort into it, only to stay the same height.

She wasn't sure when she should stop Amber from looking this ridiculous. "Umm, okaaaay...Maybe that wasn't a good idea."

Amber relaxed. She laughed, trying to hide her embarrassment and frustration at remaining the same height after her display.

"Hmm..." Sonia looked up, thinking about her encounter with Amber days earlier where she did achieve giant sizes. "Okay. You said it's usually when you complete, so you can stay intact and keep up with traps you shouldn't be able to?"

It was Amber's turn to look up thoughtfully, scrunching her forehead going over all the times she was inflated to ridiculous sizes for her normal weight class. "I guess so? Like when I have to tackle something bigger than me, or I get inflated beyond normal sizes and I just keep going. Or like my characters on game night when they get angry!"

Sonia thought about this for a moment before getting an idea. She wasn't usually a destructive giant, but given this universe's rules, she wasn't sure she could do lasting damage to Amber if she tried.

"Okay. If that's what helps you find your spark..." She drew one foot back, raised her fists. Maybe she should have a little fun.

Amber was surprised. She wasn't expecting combat as part of her training today. "Wait, what are you...?"

Sonia broke into a fit of giggles, and charged. Amber got her own hands up to stop the charge, but Sonia grew two feet just before engaging. Amber raised her arms to try and deflect Sonia's strikes...

...and Sonia gently reached around Amber's guard to tickle her sides.

"Ack! What are you doing?!" Amber jumped backwards out of the way, trying not to laugh at the absurdity of what just happened.

Sonia hadn't moved, still standing eight feet tall and cackling. "Just trying to loosen you up a little, silly."

Amber was caught between laughter and dismay.

"Well, two can play that game!"

She charged back in, fingers wiggling up at Sonia, reaching for the taller woman.

Sonia watched the attack, and noticed Amber get a few inches taller to help her reach. Her plan was working! She wondered if Amber even noticed she was growing.

The giantess grew another foot on Amber, rubbing her smaller friends hair with the palm of her hand as if she was a child.

"That's good! Keep growing!"

"Grrr!"

Amber looked up at Sonia. The giant was definitely making her mad. She felt if she could just get a little higher, she could get some revenge.

She tried to use that feeling, the drive that she knew she could succeed. Amber's footsteps fell louder, echoing through the mountain as she grew.

*WHAAAAAAOOOOOOM*

She got larger than Sonia expected, but still not big enough to be on even terms with the giantess. Sonia managed to grow another three feet in response to Amber's sudden five foot gain, ensuring she still couldn't reach her head and shoulders. Amber swiped her arms and missed Sonia's shoulders...

Leading her hands to brush the underside of Sonia's breasts as she tried to step back.

"Ha ha ha good Amber!" Sonia fought to speak through the giggles of Amber's pleasant touch. She also doubled in height in the excitement, which only made Amber's hands brush down the front of her body, down her midriff, and giving Sonia a rush of excitement.

She lost her focus and spun in place, trying to shake the feeling of Amber's touch. "You're making me lose my bal-AAANCE!"

*SQUISH*

Amber felt the full weight on the beautiful giant come down on her. Even if she herself was ten feet tall, Sonia had to be at least twenty. Her knee knocked Amber onto her back, directly under Sonia's falling hips.

Sonia rolled as she fell, stretching Amber's giant form across the floor further as her body flattened wide on the cement, but also leaving half her body under Sonia's 20 foot tall butt.

"OOOOF-oooooo that's soft..."

Any apprehension Amber had about getting squished disappeared under Sonia's marshmallow soft bottom. Rather than resisting her squishing, Amber was now melting under the butt's warmth. She felt her body splash under it, spread and splatter on the ground, and ripple with joy.

The giant atop her eventually noticed she was sitting in something gooey.

"Oof! Amber? Are you okay? Where did you...ooooo what's that?"

Fighting the urge to just run with melting on top of her new student massaging her rear, Sonia scrambled to her feet. Her hands slid and slipped in the huge blond flood beneath her, but she managed to resist joining the puddle.

Once she was back on her feet, Sonia took a deep breath to calm her emotions. Confident she was still solid, she smirked and shook her hips, watching drops of Amber tumble through the air into the rest of her.

"Well, on the bright side, I guess you did get bigger."

* * *

Amber and Scarlett had moved outside while Amber continued the tale. Amber was laying down in the grass at twice her height, with Scarlett on top of her.

Scarlett peeked out of her hiding place to look Amber in the eyes. "You are doing that to me later too!"

"Calm down my melty one. We have a lot of things to try."

Amber reached down and smashed her tiny lover between the mountains on her chest, rubbing them together to goop her up some more.

"We had other lessons besides getting huge and falling on each other."

* * *

Amber and Sonia went a few more rounds, usually with Amber getting squished and brushed aside, but Sonia couldn't keep up with the athlete forever. After Amber practically reduced her to a painting on the floor, she needed a break. Just a minute or two of not wrestling with another giant.

It wasn't her favorite thing, but she did owe it to Amber to test everything.

"So you know it's not all about big sizes, right?"

"Huh?" Amber, who was just starting to get the hang of enlarging herself, looked confused.

"Here, let me demonstrate."

Sonia charged. Amber instinctively got a little bigger and raised an arm to stop Sonia's charge, but then...

She was gone.

"Sonia, where did you go? I don't see you! How did you disappear like that?"

A tiny voice squeaked, "I'm over here!"

Amber looked in her hand. In her palm, lounging around the base of her fingers, was a very tiny Sonia. She was waving back at her.

She raised the hand with her tiny friend to her face. "Wait, how?"

"I usually don't like being small very much, but I would be a bad teacher if I didn't let you know about it. Besides, with your line of work, I'm sure this will be useful."

Amber grinned. "Yeah! No more getting barely smooshed or stopped by a fence!"

Sonia grinned and looked down. Amber had teased her enough earlier after all. "More than that! You can do this too! Scarlett will probably like it."

She jumped off Amber's hand, diving towards her chest.

Amber was slow to react. "Huh? Bwaaa ha ha that tickles!"

Sonia dove into Amber's shirt and used her tiny hands to tickle anything nearby, mostly Amber's breasts.

"Aaaahahahah! Come on Sonia get out of there!"

Amber started swatting her hands at the bump in her shirt, trying to catch Sonia. Every time she darted away, getting her hands on another part of Amber's chest, even if she was keeping things relatively playful. Unfortunately, she made a wrong turn, and ended up deep in Amber's cleavage.

Amber fought through the tingling sensation to catch her friend. "I've got-HAHAHA!-you now!"

Whether Sonia realized too late she gave Amber a chance to squish her, or if that was her plan all along, Amber's boobs closed in on her. She felt her body get squeezed and spread a little wider between the soft mountains. She lost all thickness as they smashed together.

*SQUIIIIIIIIIIISH*

Amber felt Sonia's fingers stop, but now had something else in her shirt. She pulled her tank top forwards to look inside.

Stuck to her left breast appeared to be a washable tattoo of Sonia, limbs and hair splayed out in all directions. She was also smeared to three times her normal width from Amber's force.

Amber took a few more deep breaths. She was still in good spirits, just amused at Sonia's tactics. "Was that really necessary?"

Sonia giggled with a goofy grin. "Sometimes seeing something is the best way to believe it...that and this feels nice." With that, Sonia dripped away. Amber quickly stretched her clothes out of the way and sloughed Sonia to the floor, leaving her as a tiny black, peach, and pink splat on the floor until she woke up.

* * *

"Mmmm...that sounds like fun too! Hey, don't stop!"

Amber ten feet tall, busy kneading Scarlett into a gooey red and blue ball of dough. She paused her recap to give Scarlett a solidity test. She was pretty goopey.

"Well, we will do that later silly, but I did get another idea out of that experience."

Scarlett's eyes found focus on the edges of her doughy body. "Oh? What are you going to-OOF!"

Amber punched her dough down, letting the blue and red ooze out from Scarlett's center. She clearly was enjoying it, and was in just enough of a melty state as Amber suspected.

Amber thought small, and...

*SPLASH!*

Scarlett's eyes reformed on top of her puddle. "Hey, Amber, where did you...what is that feeling? HEY!"

Amber backstroked right through Scarlett's eye, distorting and rippling it into the rest of her for a moment. "I was right! You are a great swimming pool!"

Scarlett bubbled, enjoying the sensation of Amber splashing around in her. "This is nice...shouldn't I be in one piece for the rest though?"

Amber poked one of the bubbles near her, playfully popping it. "Oh, I'm not so sure about that."

* * *

The afternoon of growing and shrinking and squishing continued. Amber was slowly easing into it, making Sonia the proud teacher of a new giant.

Not that she wasn't having her own fun.

They just finished a round where Sonia grew as fast as she could, and stomped Amber pretty fast. She wiped Amber off her shoe, tossing her floppy pink and yellow friend to the floor. "You're getting better at this! You got up to ten feet pretty fast the last few rounds!"

The 15 foot long Amber wiggled on the floor while trying to get back to three dimensions, her body shrinking back to normal size while she did it. Sonia's observation was that Amber seemed to return to normal size once she focused on anything else. It wasn't a normal thing for Amber to do without thinking yet.

Amber eventually snapped together like a rubber band, restoring herself to normal size as she bounced back. "Whew...I need to watch my step around you. One more though?"

Sonia sighed and returned to her normal height too. "Okay, fine, but only because I like growing anyway. I don't want to be too late getting home!"

They engaged again, grabbing each other's hands over their heads. Since it was their last attempt for the day, Sonia held herself back to a painfully slow growth rate, trying to let Amber grow at her own pace. Her plan was definitely working, since Amber was steadily getting faster through the day.

More importantly, right now? Amber was growing on purpose.

When they got to ten feet tall, Amber's growth rate slowed, just like it had all day. Sonia decided to poke fun at her friend, trying to find whatever spark motivated her.

*WAAAAAOOOOOOSH*

Sonia blinked, and grew to 15 feet. "Come on Amber. You don't want me to squish you again!"

She pushed down on her relatively small friend. Even at ten feet tall, Amber felt soft and squishy in her giant hands. Amber was compressed to half her height, spreading to the sides as Sonia pushed.

Sonia was careful not to completely flatten her friend, she wanted Amber to fight back. Her patience was rewarded when she felt Amber's face heating up. She wasn't getting goopey, she was getting angry.

"I...won't...give...UP!"

Sonia felt Amber's body rumbling under her palms. She was getting a lot wider too, even though Sonia had stopped pushing. What was her friend doing?

*WAAAAHOOOOOOOOOOSH*

Amber sprung up to 30 feet tall, forcing Sonia's hands back as she sprung up in her normal, if giant, shape. Sonia stumbled back, falling backwards until Amber caught her.

"Oof! Wow Amber, that was pretty good! Thanks for...uh oh."

The look on Amber's face said it all. "Oh we're not done yet."

*SQUIIIIIIIIISH*
*SMOOOSH*
*SQUELCH*

Amber brought her hands together, spinning them around Sonia. Sonia's head, arms, and legs were all crushed into her body. Amber kept spinning her hands around, stretching and smearing Sonia's features around and around until she lost track of exactly where any specific part of her was. She could tell she was in one piece, but most of her body felt smaller and rounder.

Eventually, Amber's hand pulled away. She was looking Amber in the face, rocking back and forth in her hand. She couldn't tell if she was resting on her legs or her stomach.

"There we go. I guess I won this round."

Sonia felt herself get tossed up and down. "Whooooa. Watch where you're tossing me!"

Amber smiled and tried to stifle a laugh, looking at her balled up friend. "Sonia, did you play any sports growing up?"

Sonia's eyes were still spinning. "I played softball for a little while. For some reason the league didn't want a forty foot tall player on the field though."

Amber's eyes lit up. "You played too! We need to talk about that later!"

"Oh?"

"Yeah. But for now, what's important is you already know about bubble gum."

Sonia was still woozy from being tossed in the air, but she had a bad feeling about this. "Amber? You're not..."

Amber tossed Sonia extra high in the air. "We always talk about monsters in the games doing this. I've always wanted to give it a try. In ya go."

Sonia saw Amber's teeth before her world went dark.
"ACK!"
*CHOMP*

Sonia felt her body get pinched and squoosh out in all directions. Then again. And again. Her body was getting even MORE mixed up the more Amber chewed. She felt herself getting pushed around and spread out by something warm.

She still had mixed feelings about getting chewed up, but she couldn't complain about Amber's tongue working her over. She was starting to think about how she would try this with Pepper later.

Amber opened her mouth and started blowing. Sonia's vision was nothing but pink, seeing the world as a blurry mess in her gummy state. She could barely see her reflection in a nearby mirror. Her face was just a suggestion of black lines matching her leggings against pink gum resembling her shirt. At Amber's size she must have been a ten foot bubble.

"Oh wow, I make a good bub-"

*POP*

Sonia just got a glimpse of herself splattering before her vision went pink again.

"Oops! Sorry Sonia, I thought I could get you bigger. Here, one more try."

Sonia's voice came garbled from the gum as Amber licked her up. "Mmmf! Hey! Once was enough for that today! How am I supposed to restore myself if you keep that up?"

"Oh come on, just one more? After all you squished me today you can take this. Besides," Amber paused to chew a few more, earning a few more "OOMFS" and moans from Sonia, "you're delicious! You taste like strawberries!"

Sonia felt herself getting mashed up more. If Amber wanted her to force her way out...well, Amber did want to make her a bigger bubble.

Outside, Amber kept chewing, wanting to make sure Sonia was flexible enough to be a huge bubble. She was trying to squish her against the top of her mouth, but something didn't feel right. Every time she pushed Sonia, it felt like there was more of her. Almost as if...

Then Amber felt the growing pressure against her cheeks. She tried to push them back in, but they were full of Sonia.

"Hmm? Wmmmmt?! UhhhhOohhhh..."

Amber's head kept filling with the Sonia gum growing and growing in her mouth. Amber's head started getting bigger to contain her friend, but she could feel it getting stretched out. Within seconds, Amber's head grew five times its already enlarged proportions, eyes reduced to paintings on her stretched out face.

Amber's head wobbled and rumbled, its entire surface rippling to stay intact, before

*SPLOOOOOOOOOOOOSH*

It burst in a spectacular explosion of Sonia. Her pink gum body dripped to the sides and fell to the floor with a satisfying *PLOP*.

Amber's body stumbled around, realized it didn't have a head, and collapsed like a deflating balloon. Air shot out her hallowed out neck while her body wobbled and shrank to the floor, unable to support herself or her size any longer. The shell of Amber's body collapsed into a floppy heap, while the yellow scraps of her head slowly drifted to the floor.

* * *

"WOOOOOOO!!!"

This time Scarlett refused to wait. She demanded Amber ball her up, and after building up the stories of her day so much, Amber was ready to start squishing her favorite woman.

*POP*

Amber licked the red goopy Scarlett bubble off her face.

"Oh come on, you can lick me up faster than-Mmmmf!"

"I'm TRYING babe, but you have an INTENSE cinnamon flavor. It's like constantly chewing a red hot!"

Scarlett's mangled voice came from Amber's mouth. "Mmwrfmmmwmmffmff!"

"What was that?" Amber blew another bubble, giving Scarlett a chance to speak.

"I said, we're having so much fun tonight!"

Amber nodded and tried to speak with a bubble in her mouth. "Oh yeah! I think we both learned a few tricks, and you're going to experience them first hand!"

Scarlett's face on her bubble turned curious. "Wait, what did Sonia learn."

"Oh..."
*POP*
"OOOO!"
"...that's between her and Pepper."

* * *

Sonia was lying down at giant size in her oversized bed. It may have taken hours to get out of her gumball state, but with Pepper's help she back to normal to relax before dinner. She told Pepper about everything over dinner, and came to the same conclusion Amber did.

"Pep, did you know you taste like berries?"

A blue bubble came out of Sonia's mouth, matching Pepper's hair color. Slowly, Pepper formed a face on the surface.

"That's what I've been told sweetie. You need to think like a toon more often. Then we can-WHOA"

*POP*

Sonia licked Pepper off her face. Maybe she wouldn't relax tonight after all.
