Sofia cheerfully went down the stairs, skipping two steps at a time, before arriving in the living room and heading straight for the kitchen. It was still relatively early on a weekend morning, and a comforting morning light filtered in through the windows, giving the house a peaceful atmosphere.
As she did every morning, Sofia had just returned from her daily run, and after a shower a few minutes earlier, she was about to come down for breakfast when she’d passed by the open door to Carla’s room and spotted her sister fast asleep, sprawled messily across the bed.


Back to the present, Sofia entered the kitchen, where Layla was calmly sipping a cup of coffee. “Good morning, Mom” Sofia greeted her brightly.
“Good morning, sweetheart” her mother replied “You seem to be in a particularly good mood today” “Yeah, well, the day started off very productively!” Sofia answered, slamming a plastic bottle down on the table with gusto.
It was a half-liter plastic bottle like many others, though clearly well-used, as if it had been repurposed regularly over a long time. Inside, there was no water, but rather a grayish-pink gummy substance filling the bottle completely. Looking closer, Layla recognized Carla’s extremely compressed body, twisted up chaotically to fit into such a small space.
Amid the mess of squished limbs and torso, Carla’s face could be seen smushed and distorted against the bottom of the bottle, her eyes closed. Her bare feet were also visible, pressed and deformed against the upper part and the tightly closed cap.


After taking a moment to observe her daughter inside the bottle, Layla turned calmly to Sofia, who was looking at her with a proud expression, like a cat expecting praise after bringing its owner a trophy. “You two got started early with your shenanigans today, I see” she said at last, smiling with amusement. “Yeah, but this is just the beginning! I’ve got big plans for..” Sofia began enthusiastically, but a loud snore from inside the bottle cut her off.
“Wait.. is that damn girl still asleep??” Sofia quickly grabbed the bottle and peered closely at her sister’s face. Carla was, without a doubt, still sleeping, her squished face wearing a peaceful expression as she mumbled softly in her sleep.


Furious, Sofia opened the bottle and turned it upside down, smacking the bottom repeatedly in an attempt to get Carla’s compressed body out. Bit by bit, the malleable mass slid out and landed on the table, but SPLAT!! as soon as Carla was out, Sofia’s open palm came crashing down on her, flattening her completely beneath it.
Sofia continued to smush and stomp the squishy, flattened form on the table, under the calm gaze of her mother, who kept sipping her coffee. By the time Sofia stopped pounding, the object on the table was flattened into a disk resembling a coaster, showing only the soles of Carla’s bare feet.
Sofia picked up the small disc and flipped it over, revealing Carla’s face on the other side, still squished and deformed, but most notably, still wearing the same sleepy, serene expression she had inside the bottle.


“Aaaaaaargh! How is it possible she’s still not awake after all that??” In a burst of frustration, Sofia flung her sister’s disk-shaped body away. It bounced off a couple of kitchen shelves before landing on the floor, spinning for a few seconds like a coin before coming to a stop, face-up.
Layla stifled a laugh, clearly amused, as she set her cup down and picked Carla’s flattened body up off the floor. “Time to wake up, Carla, before your sister bursts a vein” she said, snapping her fingers against Carla’s nose “Ouch!” The coaster finally came to life, letting out a long and noisy yawn. “Yaaaaaawn! Good morning, Mom.. Wait, what am I doing in the kitchen?..” Carla mumbled, groggy and confused.


Layla placed Carla’s small flattened body onto the table to give her daughter some time to properly wake up. Meanwhile, Sofia, still annoyed, was busy preparing her own breakfast. Seeing an opportunity, Sofia didn’t waste time, and SQUISH! forcefully placed her glass of orange juice down onto the table, precisely on top of her older sister’s flattened body, squishing her even further.
“Sofia..” her mother gently warned “Oops! Must’ve mistaken her for a coaster..” Sofia replied cheekily, grabbing Carla’s flattened form and casually tossing it onto one of the kitchen chairs, before sitting down on another to begin eating her breakfast.
A few seconds later, the small disk on the chair expanded rapidly, and POP! Carla’s body suddenly returned to its normal shape, upside down, legs up and head facing downward. Immediately, she fell awkwardly to the ground, met with a snicker from Sofia, who seemed slightly less irritated now.


“Ouch! Thanks a lot for the rude awakening, little sis! What time is it anyway..” Carla groaned, rubbing her head and looking around as she sat up. “That’s exactly what you deserve for being so lazy! You didn't even wake up when I squished you!” Sofia retorted indignantly, as if her sister’s behavior had deeply offended her, while continuing to eat without looking at her.
“Ah, now I’m starting to understand how I ended up here in this situation.. Thanks, Mom” Carla said, accepting a cup of coffee from Layla. “Let me guess, Sofia: you stuffed me into that plastic bottle again, right?” she continued, sipping from the cup.
“Huh? But you were asleep, how did you..” Sofia started, astonished, but Carla cut her off.
“You've become predictable lately, sis” Carla placed her cup down and extended her hand toward Sofia, three fingers raised: “Compressed inside the usual plastic bottle. Rolled into a soccer ball. Or squished between your enormous boobs. Whenever you want to squish me, it's always at least one of those three methods!” Carla declared theatrically and smugly, as if revealing the culprit at the climax of a detective series.


Sofia tried to respond, annoyed by Carla’s attitude, but couldn’t find anything to counter with, and instead just glared at her. Satisfied, Carla lowered her hand and continued sipping her coffee. “Of course, eventually, I got used to your same old squishings.. Actually, now I find them quite relaxing” Carla continued with a smug expression.
Sofia stood up angrily from her chair “Oh really? Well, turns out I've been going easy on you because of your frailty and weakness. But if that's how you see it, I'm gonna start taking it seriously!” She immediately moved to grab her sister, but a deliberate cough from their mother stopped her immediately. “No squishing in the kitchen, girls..” Layla said in a monotone voice, her back turned as she washed the breakfast cups.


Unable to freely squish her sister, Sofia instead addressed her with a challenging tone: “Fine! Let's do this then! Today, you'll accompany me on some errands, and you'll be completely at my disposal as my personal squishy toy for the entire duration! If at any point you return to normal or complain, then I win!” Sofia exclaimed at Carla, who after a brief moment of surprise appeared quite intrigued.
“I like it! Finally, a decent idea has come out of that pretty little head of yours” Carla teased back, also standing up and matching Sofia’s tone “And if I manage to withstand your pathetic attempts at annoying me, then I’ll be the winner!”
“What’s the stake, the usual?” Carla asked, extending her hand to officially seal the challenge “Of course! The loser will be at the winner’s complete disposal for a whole day!” Sofia answered, reaching out and firmly shaking her sister’s hand. Both sisters wore confident expressions, each convinced victory was already theirs.


“I’d start right away, but I'm tired of seeing you leave the house in pajamas, go get changed!” Sofia said, releasing Carla’s hand “And hurry up; I want to leave soon” “At your orders, little sis!” Carla replied, giving an exaggerated military salute and practically sprinting off to her room to wash up and change.
Carla was visibly excited: not just because of the challenge, but also because she genuinely enjoyed spending time with her younger sister (despite the bizarre circumstances). But in recent years, Sofia rarely invited Carla out just the two of them; ironic considering that, when younger, she and that little tomboy had been almost inseparable..


Layla also noticed her older daughter’s enthusiasm: “You really made her happy” she said smiling, turning toward Sofia “It’s obvious she couldn’t wait to spend some time with you”
Sofia turned her gaze away from her mother to hide the embarrassment already coloring her cheeks red: “Oh yeah? W-Well, good for her; she'll soon bitterly regret accepting the challenge!” she exclaimed, marching quickly out of the kitchen.


**********************************************


A short while later, the two sisters were both in the living room, ready to go out. Sofia was wearing her usual sporty black shorts, a matching black shirt, and her beloved purple sneakers, while Carla had opted for a grey tracksuit that, truth be told, strongly resembled her usual grey pajamas. The only noticeable differences from her usual appearance were her hair, typically messy but now braided neatly, and the flip-flops she wore.
"Seriously, you're going out dressed like that?" Sofia questioned, scanning her sister from head to toe "I figured I won't spend much time in my normal form anyway, so might as well dress comfy, right?" Carla replied nonchalantly "Hmph, at least you realize what's waiting for you" Sofia answered, opening the front door.
"Mom, we're going out!" Carla yelled toward the kitchen as they stepped out "Enjoy your walk, girls!" came Layla’s voice cheerfully in response.


Outside, morning sunlight lit up the neighborhood, but a gentle spring rain had begun to fall lightly. Carla extended her hand beyond the threshold to feel the raindrops: "It's starting to rain, let's grab umbrellas" "No need, I've already got mine right here" Sofia replied mischievously, placing her hands on her sister's shoulders.
A few squishes later, Sofia was walking toward the city center alone, beneath a colorful umbrella. None of the few passers-by paid her much attention, but had they looked more closely, they would’ve noticed that the umbrella was actually Carla’s squished body.
The long, thin grey handle was made of Carla’s legs and torso, compressed into a slender tube shape, with her arms pressed tightly against her sides. The umbrella canopy itself was entirely formed by Carla’s face, stretched and distorted into the umbrella's dome. At the moment, a serene expression adorned her features.


"I have to admit, you're being pretty creative this time, sis" Carla remarked, talking normally despite her unusual shape "This light rain feels almost like a massage on my face.. hehe, it tickles!"
"Of course someone as weird as you wouldn't be bothered by this.." Sofia shot back irritably "And quiet down! Umbrellas don't talk!" she hissed, glancing nervously around to ensure no one had noticed.
"Eeeeh? But it's boring if I can't talk!" Carla protested, and Sofia could tell she had an exaggerated pout on her face, even without seeing it directly "Besides, it’s not often we get to chat alone together calmly since.." Carla began but hesitated mid-sentence.


"What do you mean? Since when?" Sofia pressed, but Carla swiftly changed the subject
"Oh, nothing. I was just thinking we’ve been squishing each other more often lately, right? It's rare for both of us to be normal in the same room" "That's your fault for always acting so superior! It just makes me want to squish you right off your high horse" Sofia snapped, gripping the umbrella handle tightly and further deforming her sister’s body.
Carla took a few seconds to reply: "I honestly feel like the most chill and relaxed person in the world, not superior" she responded, sounding slightly offended "Of course, if you’re always harsh and violent, then I can’t exactly help..UMPPFFF!" Carla’s response was abruptly cut off as Sofia suddenly started balling up the malleable umbrella in her hands.


"Provoking the person who’s got control over you today isn't very smart.. and you’re supposed to be the intelligent one" Sofia scolded as she continued compressing the umbrella until it formed a colorful ball roughly the size of a baseball.
“With your next shape, I doubt even you’ll be able to talk" Sofia declared smugly, casually tossing and catching the protesting ball as she walked toward a bench to reshape her sister properly.
A few minutes of fiddling later, Sofia held Carla’s new yo-yo form in her hand: Carla’s head had become the typical round shape of the toy, her face printed on one side and the back of her head on the other, with no visible trace of her body.
"Once again, nice idea, little sis, but as you can see, I'm still perfectly able to talk like thiiiiiIIIIIIIIS!" Carla’s sentence was suddenly cut short as Sofia flung her downward, unraveling the yo-yo string formed from the rest of Carla’s body, now reduced to a thin cord, making Carla’s head rapidly spin.


Just as Carla’s spinning head reached its lowest point, Sofia skillfully flicked her wrist, winding back the cord and pulling her sister’s head, still spinning rapidly, swiftly back up into her palm.
Carla’s face now showed an extremely dizzy expression, with vacant eyes and tongue hanging out comically: "Aaah.. Everything’s spinning.." Sofia chuckled in satisfaction and resumed walking, happily playing with her new yo-yo.
"Finally, some peace and quiet" Sofia thought, enjoying the silent stroll, interrupted only by occasional incoherent mumbles and confused sounds from Carla, who continued spinning uninterruptedly, up and down, in a perpetual loop.


**********************************************


It was now late morning, and Sofia had almost finished her errands in the city. During all that time, she had kept Carla in yo-yo form, as she was having way too much fun playing with her sister’s body that way, enjoying both her silence and her dizzy expression and moanings.
After walking through the city center, Sofia took the path through the park to head back home. It was fairly empty, free from the usual city crowd. "I'm starting to get a little bored, to be honest" Sofia thought to herself, holding Carla’s small body, still out of commission, in her hand. "Let’s see what form I could squish her into next.."


But just as she was lost in thought, Sofia suddenly felt hands press down on her head from behind. "Good morning, Sofia!" she heard, but before she could even turn around, those hands pushed down hard on her head, rapidly compressing her body until SQUISH! she was completely flattened on the ground.
Towering over her was Mia, dressed in athletic clothes, apparently out for a jog in the park. Sofia, now squished flat to the ground, had taken the shape of a flat disk: only the top of her head at its center and the outline of her black shirt were visible. However, her body wasn’t completely flat: her enormous boobs had remained three-dimensional, possibly even larger than usual due to the mass redistribution.
From a distance, all that could be seen of Sofia were those two giant black globes resting on the ground.


"What a nice surprise running into you here" Mia said, looking down at her friend with a smug expression. "Wait, let me squish those melons of yours too, just to tidy things up" she added; Mia then pressed both hands firmly onto Sofia’s enormous boobs, flattening them one after the other until they, too, were thin like the rest of her. Sofia’s whole body was now flat on the ground, only a few centimeters thick, with a circular shape, except for her chest, which protruded forward and broke the symmetry.
"I’m sure you know this already, but this is revenge for using me as a yoga mat the other day" Mia said, picking Sofia up from the ground and waving her around like a sheet of paper. With her face compressed along with the rest of her, the squished girl couldn’t react or speak in any way.
"You’re officially invited to my place to help me finish my morning workout.. Now let’s see, what form should I squish you into?"


Finding little satisfaction in teasing her helpless and silent rival, Mia began folding Sofia’s body over itself several times, until she was reduced to the rectangular size of a black card, only a few centimeters long and several centimeters thick. With one final squish between her open hands, Mia compressed the card further, down to about a centimeter in thickness, and slipped it into the pocket of her athletic shorts.


Pleased with her unexpected catch, Mia was about to resume jogging when she noticed something on the ground that had fallen from Sofia’s hand. She leaned down to pick it up: it looked like a yo-yo, but if there was one thing Mia had learned after all these years with Sofia..
"Good morning to you too, Carla" Mia said, picking up her small body  "Another round of sisterly shenanigans, I take it?" "Ah.. hey, Mia.. Yeah, you could put it that way.. Where’s Sofia?" Carla asked, still slightly disoriented from all the spinning.


Mia patted the pocket where she had stashed Sofia’s squished body "Nice and safe in my pocket for now.. but the real fun will start once we get to my place"
Carla seemed to shake off her dizziness: "Listen, Mia, we were in the middle of some sisterly time together, and I’d really appreciate it if you didn’t interrupt that. Could you please settle your score with Sofia some other time?" she asked, her serious tone quite in contrast to the tiny and ridiculous form she was currently shaped into.
Mia was caught off guard by the request. Carla was usually pretty indifferent to getting squished, whether it was her or Sofia. But she had no intention to give up her prize; if anything, she was planning to double down: "Sorry, Carla, but I’m not letting Sofia go that easily. If you want, I can include you too; maybe squish you both into one combined object!" she teased, gripping Carla in one hand and bringing the other closer, intending to smash her in between.


What happened next was all very fast: before Mia’s hands could meet, Carla’s body began to vibrate and instantly expanded back into her original shape. Mia barely had time to gasp in surprise and take a step back, but Carla was quicker. With two swift steps, she closed the distance and SPLAT! slammed her palms together on either side of Mia’s head, squashing it between them.
When Carla moved her hands away, Mia’s face from the front was almost completely invisible, reduced to a narrow strip only a few centimeters thick. On either side, the halves of her face displayed expressions of shock and surprise. A few seconds later, Mia’s entire body collapsed to the ground, out cold.


"I tried asking nicely" Carla said, rubbing the palms of her hands "but just like Sofia, sometimes the only thing you people understand is force"
Firstly, she retrieved Sofia’s card-shaped body from Mia’s pocket and tucked it safely into her own. Then, she turned her attention to Mia’s defenseless form and began rolling her up from the head down, as if she were a carpet.
As the roll moved further along Mia’s body, more and more of her was inevitably squished and wrapped up with the rest, until Carla was left holding a multicolored roll about the size of a small rug.
"Now, what should I do with you.. I don’t want you coming back to bother us, so let’s find a nice place to leave you for the rest of the morning.." Carla said, talking to the roll with a mischievous look as she glanced around. Her eyes landed on a mailbox just outside the park "Perfect"


Carla set Mia’s rolled-up body on the ground and began flattening it further until it became a long, rectangular multicolored strip. Then, she rolled it up along its length until she was left with a small cylinder, roughly ten centimeters long.
With Mia dealt with, Carla headed over to the mailbox, opened the hatch, and slid Mia’s cylindrical body inside. It vanished instantly, and she shut the hatch behind her. "With a bit of luck, someone might pull her out later today.." Carla thought. "Though who even sends letters through mailboxes these days? Eh, hopefully someone does.. for her sake"


Once the nuisance was taken care of, Carla sat down on a nearby bench and placed Sofia’s card-shaped body beside her, waiting patiently for her sister to recover from the squishing. After several minutes, Sofia’s body gradually began to expand, slowly returning to its original form.
"Uurgh.. What happened? I think I heard Mia’s voice.." Sofia muttered as soon as she was able to speak, struggling a bit to sit up on the bench "Mia tried to squish you as revenge for that yoga mat thing the other day" Carla explained calmly "But I managed to convince her to back off for now. She left."
"You sure?" Sofia asked, a bit skeptical "She is not exactly the kind of person who gives up on her prey that easily" Carla responded with a casual shrug.


"Anyway, I’ll make her pay for sneaking up on me like that!" Sofia huffed, rising from the bench, now fully recovered from the experience "Sure, sure" Carla replied in a condescending tone, standing up as well "But don’t forget our little challenge from earlier. You still haven’t managed to make me give up"
Sofia turned toward Carla, as if just now remembering the whole point of their outing: "Of course! Don’t think I’m done with you yet, big sis!" she replied, starting to walk again, Carla following close behind. "I was just thinking about what to squish you into next before Mia showed up. The yo-yo clearly wasn’t enough to break you"
"I’ll give you credit for creativity, but the constant spinning was really annoying" Carla admitted "I think I could’ve endured it until we got home.. but if I may request a favor, could you try something else? Unless you want me dizzy all day"
"Alright, I’ll grant you this favor as thanks for rescuing me from Mia" Sofia conceded "But I will make you break before the day is over!" she added, staring at Carla with determined eyes.
"Bring it on, little sis!" Carla answered, just as fired up.
