— Alright — the woman smiled professionally to the couple — Are you both okay with this?

— Sure! — Greg had a dumb smirk on his face, having troubles to contain his excitment.

— Not really — said Eve, looking down to the floor.

— Seriously, Eve? — the guy crossed his arms — We’ve already talked about this many times and you agreed. How come you are having second thoughts now?

— It’s easy for you to say! — she pushed him away — You are not the one who’s gonna be… filled…

The woman put herself between the two and rested a hand on their shoulders.

— Excuse me, please? May I ask what’s the relationship between you two? — even under that uncomfortable situation, she managed to keep a straight face — Boyfriend and girlfriend?

— Hell no! — Eve showed her tongue — We are brother and sister.

— Interesting — the woman scratched her shin, studying both of them from the bottom up — May I ask you, mister Greg, why you want to turn your sister into a balloon toy against her will?

— We had a deal! — he pouted — We’ve been sharing a house for a while, which requires a lot of cleaning and maintenance. My dear sister over here told me she needed time for a very important project, so I was in charge of all the domestic chores for three months… Given she would return the favor by becoming my toy for a month after the project was done.

— Interesting — she raised an intrigued eyebrow — Is that true, madam Eve?

— Y-yes… We kinda had a deal — she blushed and stepped back — But I’m having second thoughts now…

— Don’t worry, madam. The process is completely safe and temporary — she continued to display that salesperson smile — Once the effects expire, you’ll be back to your normal flat self.

— Hey! Rude! — Eve covered her tiny breasts and blushed — How dare you?

— I’m sorry. I meant no disrespect to your chest — the woman giggled — I was referring to “flat” as the opposite of “full of air”. I should've chosen my words more carefully.

— Can I make my sister’s breasts bigger?

— Once we start the inflation, you can customize her to your likings!

— Excuse me! — Eve jumped in place and shouted — I’m your sister! Don’t you dare make me a sex toy! That was NOT part of the deal!

— I’m not deranged, Eve — he made a disgusted face — I’m just gonna give you a cute animal shape… with swollen boobs…

— That’s completely unnecessary! — she protested, still hugging her own chest in a protective way.

— Hey! It’s in our best interest that you look unrecognizable — he crossed his arms, then displayed a trickster's smile — That’s why I’m going for an animal balloon with big boobs. If you become a flat chested toy, I’ll still see too much of you in it…

— I’m gonna punch you so much when this is over…

— Mister Greg and Madam Eve! — the woman interrupted — You can discuss the customizations later. However, right now, I still need madam Eve’s consent to this. So, I’m gonna ask it one more time. Do you agree to be changed into a balloon toy with the characteristics of your brother’s liking for the period of one month?

Eve bit her lips and cringed, but didn't usher a word.

— C’mon, sister! It’s either this, or you’ll do all the house chores for a year!

— A year? — she gasped — That’s not what we agreed upon! Don’t go changing our terms!

— Exactly — Greg smirked — We agreed upon one month as a toy. You are the one trying to change the terms! I thought I could trust your word!

— Fine! — she yelled and turned to the woman, but still Eve didn’t have the guts to look her in the eyes — I give you my consent to be changed into a balloon toy for a month.

— “A balloon of my likings” — Greg added.

— Damn it! — Eve clenched her fists — Okay! Okay! Let’s get this over with!

— Excellent — the woman clapped her hands twice — Let’s get started.

---

Eve was directed to a changing room where she could undress in private and replace her regular panties and bra with specially designed ones, made of a very fragile fabric that would easily and painlessly rip apart once her body expanded. Those garments were supposed to temporarily cover her private parts until it changed into the smooth, featureless surface of a rubber toy.

Eve was also given some “elasticity pills” and asked to wait in a warm room for a few minutes. The woman would come in at regular intervals, pull her index finger and measure how much it stretched with a simple ruler. Once Eve’s newfound elasticity allowed her appendage to extend twice it’s natural length, the woman seemed satisfied with the results and asked her to get up.

— This will feel a bit weird, but you don’t need to worry — her smile never faltered — Relax.

The woman closed her fists and pressed it gently against Eve’s belly. Slowly, she started to put more pressure on, causing the fist to painlessly sink into her skin just like it would sink in a regular balloon. The girl’s body even creaked in response, gaining a rubbery texture.

— S-stop it! — she squirmed in place, biting her lips and closing an eye — I’m gonna… I’m gonna…

Once the woman’s arm had sunk a few inches past the wrist, an immense pressure formed in the girl’s bowels and, soon enough, she wasn’t able to contain her natural gasses anymore. A long embarrassing fart, that sounded just like a party balloon being deflated, came out of her butt in response to being pressed.

Ppprrrffffffffchhhhh!

— Stop! — Eve’s face turned red as her body helplessly continued to fart, filling the small room with the smell of latex — Stop! Please!

— Don’t worry, darling — the woman was unfazed — This is all natural.

The arms continued to sink into her, and Eve released one fart after the other, each of them louder and longer than the last.

Desperate to fight for her dignity, the girl put her hands on the woman’s shoulders and used all of her strength to push her away. However, all that effort wasn’t able to accomplish anything useful, quite the contrary. Eve’s arms bent in a scary angle that made her yelp and widen her eyes in horror.

She was so scared when her arms broke that Eve immediately stopped pushing the woman. Once she did it, her arms sprang back to the original shape like a rubberband, wiggling and shaking uncontrollably for a few seconds. Even her bones had become elastic at that point.

— Impressive, right? — the facility employee said, as if nothing out of the ordinary was going on — You are almost ready to be filled.

Despite the interruption, she continued to press her fist even deeper on Eve’s belly, triggering more farts and gasps of protest. Her arms went all the way to the girl’s tailbone at the other side, and continued to force her way even past that point, forming a bulge on top of her ass, right between the buttcheeks… Almost as if a tail was erupting.

— No need to be embarrassed, madam — another push, another fart, and her tail-like protrusion bulged out a few inches — You are doing great.

Eve tried to fight a second time, using all her might to pull that fist off of her, but all she could do was bend her arms again and again, without moving that unwelcome limb a single millimeter. It was as if Eve had lost all of her strength. Her body offered no resistance and the woman could do whatever she pleased with her.

— Sto-buuurp! — the girl’s words were cut short by an accidental burp — I said stoo-buuuuurp!

Realizing that neither words nor brute force were an option, Eve tried to run away. But as soon as her legs moved, the woman picked her up with one hand and effortlessly lifted her from the floor, placing the soon-to-be-ballooned girl on her shoulder. Her body wasn’t only infinitely weak, but also seemingly weightless at this point.

Eve kicked the woman’s chest and punched her back like the stereotypical damsel in distress, yet her flailing limbs did nothing but produce squeaks with each impact. Her cries of anger came out as humiliating belches, each of them weaker than the last, until Eve’s lungs were completely empty and she found herself unable to speak… and unable to burp…

She eventually tired out and gave up, allowing the woman to continue pushing a long tail out of her butt from the inside. The feeling was equivalent to nothing she had ever experienced before, and the closest comparison would be having a super-powerful plunger sucking her skin out… yet, it was still an inaccurate comparison.

Once that arm was shoulders deep into her, the woman maintained the pressure for a few seconds more then, for Eve’s relief, slowly pulled it all the way out and placed the girl back on the floor.

Her belly had returned to the original shape with no signs of ever being assaulted, however things were a bit different on the other side. A long tail dangled from Eve’s butt, brushing against her legs in a discomfortable manner that tickled her skin.

She tried to move her tail away, but soon realized she had no control over that limb. It was just a bunch of flaccid skin with no muscles or bones. Her only option was to spread her legs a bit and keep both of them away from the tail, which now moved slowly like a pendulum, swaying left and right with the weakest gusts of wind.

Eve opened her mouth to ask questions, but only a short hiss came out… like the last sound of a deodorant spray before completely emptying.

— Speaking is off limits now, madam Eve — she said in a calm tone — I’m gonna ask you to communicate with nods and headshakes if possible. Do you comprehend?

Eve nodded in affirmation, before blushing and looking down. She nervously held her tail with both hands and squeezed it. Everything inside her was soft and elastic. She had never felt so powerless in her life.

— Please hold still while I put some equipment on you.

The woman proceeded to wrap straps of different sizes around Eve. One at each knee and elbow, one in the waist, another right below the breasts, one at the base of her tail, one at her hips and the last one around her neck. Each of them was pressed tightly against her rubber-like body, forming wrinkles around them. The one on the neck was the most uncomfortable one, and it would surely suffocate Eve if it wasn’t by the fact she somehow didn’t need to breathe anymore.

— Is it hurting?

Eve pondered for a while, then shook her head negatively.

— It’s supposed to be a bit uncomfortable, but not painful — she double checked each strap, moving some of them a little bit and tightening the ones that seemed loose — Don’t worry. They will all come out at the end of your conversion.

Eve’s natural instinct was to swallow in response, but her body wasn’t producing saliva.

— Please, follow me — the woman gestured.

The girl had no option but to obey. She walked out of the room barefooted, each of her steps followed by a squeak and a creak as her body bent and compressed. Her tail swayed lazily and was constantly touching her inner legs, which forced Eve to spread them apart and waddle around in a ridiculous unnatural way.

Her brother, who was waiting at the other side, smiled at the first sign:

— Nice tail.

Eve tried to say “Shut up, Greg”, but instead of words, she produced a timid rubber squeak.

— Oh, you can’t respond? — he teased — I guess you won’t be able to bother me with your constant nagging from now on.

The girl slapped her brother immediately with the strength of an air baton, which was very loud, yet completely painless. She continued to hit him again and again, venting all of her frustration at Greg, who simply stood in place, perfectly still while his body received the most laughable assault ever. His sister's punches were reduced to silly baps.

— Guess I also won’t be bothered by your violent tantrums — Greg picked her up by the waist and lifted his older sister above his head — Nice…

At that point there was no turning back. Eve didn’t want to continue making a fool of herself, so this time she surrendered and allowed herself to be handled. There was no point in fighting, since she had the strength of a party balloon.

— She’s really light — said Greg, tossing her up in the air and catching her again repeatedly as if she was a beach ball.

— As light as any regular inflatable toy — replied the woman — I recommend keeping it indoors, because it can accidentally fly away on a windy day. But if you really want to play outside, keep it on a tightly held leash.

Eve turned red as they seemed to have forgotten that she was a living person. Their talk made her feel as if she was no longer their equal… It was like her consent to be balloonified also meant signing away her human rights…

Yet, the worst part was that she couldn’t even speak out against that disrespect. Even if moving was still possible, it was useless since anyone could stop her with a single finger.

— What are all these straps for? — Greg raised an eyebrow — It's not very aesthetically pleasing to look at.

— Don’t worry, mister Greg — said the woman in her sweet voice — These are simply required during the inflation process. It allows us to independently control how each part of the toy’s body is formed. We take them out once the balloon is finished.

“Toy?”
"Balloon?"
She was a person!
She had a name!
Eve gave those two no permission to refer to her as an object!

— Sweet — he held Eve with one hand and pulled her tail with the other — I can control how much each part of her inflates?

The girl tensed her body when the tail was pulled. Her ass tightened, almost showing it off to her brother. A cry of protest formed, but it came out as a silent squeak.

— Of course. You can also decide the shape of each part.

— Animal shapes are possible?

— Totally!

— Can I make her huge?

— Not exactly — the woman cleared her throat and changed her voice to a more technical one — Once inflated, the balloon will start to naturally lose air as time goes by until it’s empty enough for the changes to fade away. The duration of the changes is proportional to how much air we use, so you’ll get to choose how to distribute one month worth of air. That 's the limit.

— One month of air? — he looked at Eve, then back at the woman — How much is that in volume?

— If you decide to distribute it evenly, it is enough to triple her size.

“Triple? I won’t be able to pass through doors!”

— That’s a lot — Greg sighed — I was expecting her to be a manageable size, if you know what I mean. More of a pool toy for one person, rather than for a group.

Eve almost felt relieved with that. Maybe her brother decided to reduce her sentence by a few weeks due to size concerns… But then, the clean salesperson voice spoke again:

— You can grow its body up to the desired size, then use the remaining air to fill its tail — she smiled — That’s what most people do. You get a toy with the perfect size and the tail acts as an air reservoir. Some clients have even told me huge tails make very good beds.

— Well, sister… Let’s see how big this tail of yours can get.

Eve cringed and turned red...

---

Eve was led by the hand to a corner of the room, where a long unassuming hose was waiting for her. The girl held her tail with both hands so she could walk normally instead of waddling clumsily, but still her steps were accompanied by annoying squeaks, which didn’t sound one bit like the “human” footsteps of the other two.

— I’ll be filling the toy, part by part, until you tell me to stop — said the woman — Once you are satisfied with the overall size, I’ll use the rest on the tail. Understood?

— Alright.

Eve was growing constantly more annoyed by the fact neither of them seemed to consult her opinion anymore. She was about to be “customized” and everyone was acting as if there was nothing weird about that.

— Do you have a specific color in mind, mister Greg?

— Blue! Wait, no! Light blue!

— Excellent choice! — she smiled and pressed some buttons on the screen — Light and pastel colors look very cute in most balloons.

There was something very dystopian about that conservation, which caused chills on Eve's spine. Hearing another person deciding a new color for her skin, while she was unable to speak, made her wonder if her own brother had somehow been induced to stop considering her an actual person.

— Where should we start? — the woman took the hose and approached Eve like a nurse about to do some mundane thing.

— Let’s fix her flat chest first — he said, with a chuckle.

“Screw you!”

The girl tensed up and bit her lips when the hose was pressed against her left boob. Instead of pushing her rubber skin inwards, the hose somehow passed through the surface and went into the body, visibly penetrating her without causing any pain.

The alien object made Eve shiver and cringe, shocked to have anything trespass into her boundaries like that. The sensation was akin to having a soft object stuck between her muscle fibers, gently pushing them apart. Eve would grumble in response if she had any voice left.

— Tell me when to stop — usually, that kind of thing should be directed to Eve, but given her apparent lack of “human rights” the woman directed the word to her brother...

A constant stream of warm air was pumped directly into her chest. Both boobs grew at the same rate, taking a perfectly round shape that Eve always envied in other girls. She almost felt thankful for being able to experience what an actual busty chest was like…

Despite the embarrassing situation, her nipples hardened and pushed against the fabric of the bra. That erection was partly caused by the air, but Eve couldn’t deny that there was a bit of pleasure involved too. She was partially glad to lose her voice, otherwise she would start moaning.

Sadly for her, the inflation was soon accompanied by a change of colors, turning her chest into an artificial light blue tone that had nothing human about it. Since the rest of her body still had a natural skin color, those bloated breasts looked more like balloons that had been glued in place. Looking from far away, people would most likely think it was a weird costume.

After a few seconds, her boobs grew to the size of melons, their squeaky forms rubbing against one another and acquiring a shiny surface that reflected some of the light. The threads of her bra ripped one by one as those breasts continued to swell past the reasonable size. Eve no longer had the D-cups she always dreamed of, but a massive pair of balls as big as her head.

Her bra suddenly snapped off and flew away like a rubberband, leaving her huge watermelons bouncing in resonance for anyone to watch.

Eve immediately covered them by instinct, but as her palms reached for the round nipples, she realized there was nothing there. Her light blue boobs were completely smooth, devoid of any features except for the exaggerated size and the rotund shape.

Her skin continued to stretch out more and more, creaking and becoming see-through, revealing her empty insides. Those gigantic balloons seemed to grow without limit... until a sensation similar to a muscular cramp took over most of Eve’s chest, causing the girl to tense up and hiss. Thankfully, before it actually started to hurt, the inflation was interrupted.

— That’s enough — said Greg.

The woman turned off the pump and slowly removed the hose from her chest. Eve could swear that thing had penetrated her skin, but there were no marks anywhere. It was like her surface could open and close on its own whenever the equipment needed to get in or out.

— We must give it a few seconds to accomodate to the new shape — said the woman, in her technical voice, then she finally directed a word to Eve — Right now you must be feeling a slight tingling and a bit of a stretching sensation. It means your body is still adapting. Once you stop feeling the stretch, we’ll resume the inflation. Understood?

Eve nodded in response, partially happy to be consulted about her state.

— What happens if we don’t wait enough? — Greg asked out of curiosity.

— Then your toy will get floppy and wrinkled. Not one bit like the high quality balloons we pride ourselves with making — the woman frowned — To get the perfect finish, it requires the right amount of time between pumps.

Eve looked down and couldn’t even see her feet given how big those breasts had become. She could probably touch them with her chin if she wanted to. Those things were massive and hypnotizing, so she quickly found herself playing with them. She wished they could just end her transformation right there and leave her with those bloated babes…

— Having fun there, sister?

Unable to respond to the provocation, she used the only form of communication available: Eve flipped her middle finger.

— How about that stretch? — asked the woman, always professional despite the teasing among siblings — Do you still feel your skin pushing?

Eve shook her head negatively. Although she still felt those balloon boobs pressing against one another, the cramps and the painful stretch were gone. It was as if her boobs had always had that size.

— Perfect — the woman looked at Greg — What’s next?

— The belly — he said — It won’t be a good balloon toy if it doesn’t have a huge, blimpy belly. I want her to be big enough for me to bounce off it and use her as a ball..

— I must say, mister Greg, you really know the qualities of a good balloon.

The hose was inserted into her bellybutton, once again trespassing the skin effortlessly. A button was pressed and the warm air began to fill her up slowly. First, only the region around the belly button bulged out, causing her panties to slide down a bit. After almost a minute, the expansion spread more evenly, bloating her waist to the sides and filling her stomach.

Eve’s torso lost its athletic curves and merged into a smooth blob of air. People could no longer point out where her waist ended and where the belly began. Everything between the hips and chest became more akin to a sphere than a human shape. On top of that, her skin also changed into a light blue color as it stretched out. The sensation was similar to drinking lots and lots of soda, causing her guts to become gassy and start to rumble.

Her stomach reached its limit and a burp rushed to the nearest exit, but got stuck somewhere just below her chest, imprisoned by one of the many straps tightly wrapped to her body. Eve was thankful that the belch was contained, but then her stomach continued to enlarge with more gas, begging to be emptied. With no way out, the gasses moved in the alternative direction...

Her intestines also filled up quickly and, just like before, the air rushed out to the nearest exit. However, the straps on her hips didn’t seem to be tight enough, which allowed the air to escape in the form of a warm continuous fart. Eve desperately tried to clench her legs and even cover her butt with both hands to stop the leaking, but those efforts only made it sound more flappy and ridiculous.

— Jeez! — Greg laughed — Where are your manners?

Despite her brother’s teasing, Eve was continually forced to release a massive bout of gas against her will.

The woman stopped the pump, but didn’t take the hose out. In a matter of seconds, she grabbed both ends of the strap and pulled it until the gas was completely sealed.

Eve’s belly bulged out immediately when some of the air was squeezed back in, and every inch of her skin stretched almost to the point of ripping apart. Loud creaks were followed by a dozen cramps and she tensed up in pain. Her mouth opened in a silent yelp and a tear ran down her left eye. If a balloon had feelings, that was probably how it felt moments before blowing up.

— Hey. I didn’t tell you to stop! — Greg stomped his feet, sounding more like a spoiled brat than the young adult he was. The guy was clueless to the near-explosion experience his sister had just went through.

— I know, mister Greg — she talked without a hint of concern in her voice — Depending on how big you want its belly to be, it requires some intervals to let the air accommodate. If we filled its belly in one go, your pretty toy would end up with lots of stretch marks. You wouldn’t want that, right?

— Sorry… I didn’t know about that.

— No problem — she smiled — We are professionals here. Let us worry about all the details for you. Just focus on customizing the toy to your liking.

The woman hugged Eve from behind and started to massage her beach ball sized belly, alleviating most of the pain and sending the cramps away one by one. The girl closed her eyes and enjoyed the relaxing rubs. It was nice having someone care about her wellbeing, instead of treating her like an object.

However, that didn’t last long. As the woman continued to rub her belly, she said:

— Lift your right hand once you stop feeling pain, my cute balloon.

“I have a name.” she wanted to say. “Don’t call me a balloon or a toy. I’m not an object.”

However, the caressing on her bloated belly felt so good she didn’t even want to protest. Eve relaxed her body completely and allowed the woman to continue her work. Those professional hands knew exactly where and how to press. Each movement was precise, eliminating the pain wherever her fingers passed.

— Feeling good, my adorable balloon?

“Y-yes…”

— Are you relaxing, my soft toy?

“Y-yes. I am…”

— You are good floatie, darling...

Whenever the words “toy”, “balloon”, “plaything”, “floatie” or anything else was whispered, those fingers would reach one of Eve’s many stress points and release the tension on those rubber muscles. Each relief was followed by an affirmation telling Eve she was a pretty toy. She subconsciously started to associate being called an object with feeling good.

One stroke…
One cramp disappears…
Her body relaxes…
She hears: “Good toy.”

— How about now? My adorable inflatable thing. Do you feel any pain?

The girl shook her head in negation, barely aware of her surroundings.

— Time to continue the inflation.

The hose was turned on again and her already huge belly stretched out even more, until it became immense. In fact, it was so big that her legs were pushed to the sides and Eve had to be held in place by the woman, otherwise she would lose balance and fall.

When the pressure rose and her insides began to rumble again…
A loud fart escaped her ass, signaling that it was time to make another break…
The straps on her hips were tightened even more to match the rising pressure…
The cramps and the pain came back as a result of the overstretching…
And then, Eve was massaged for many minutes to alleviate the side effects, constantly receiving more affirmations that, when combined with the relaxing bellyrubs, seemed to replace her critical thinking with a submissive bliss.

Greg wasn't satisfied with her size, meaning Eve had to endure many cycles of inflation and massaging until finally getting as big as he wanted. However, she was starting to like that process. Being caressed and called an “adorable balloon” was inflating her ego and giving the girl a sense of fulfillment. It was as if her life’s purpose was being achieved.

At that point, Eve appeared to be wearing a big-breasted blueberry costume, with her head, arms and legs sticking out of her spherical center. However, a closer look would reveal that it wasn't a prop, but the girl's body itself. It was even possible to see past her light-blue, transparent skin, like any regular balloon.

Once the girl appeared to have swallowed a full yoga ball, her brother finally told the woman to stop. Eve almost got angry at him, because she wanted to get even bigger. But questioning the decisions of her owner wasn’t a sign of a good toy, so she kept her thoughts to herself.

— What 's next, mister Greg?

— Well… since we are on the way down, I guess the next step is her butt.

This time, instead of mysteriously passing through her skin, the hose was pushed right up her asshole, using the entrance that was already there.

The shock caused Eve to wake up from her submissive stupor and return to her normal self.

“I’m not a toy! I’m Eve!”

She jumped away, causing the hose to detach with a "whumpf!" sound. However, her belly was so big at this point that Eve tripped on it’s own bloated mass and fell on her fours, balancing all of her weight on top of the huge round ball that was her torso.

Unable to get up, Eve accidentally placed herself in an even more vulnerable position. The woman had no trouble pressing one hand against her back, to keep the girl in place, and using the other one to shove the hose up her ass a second time.

And unimaginable urge to fart took over her, but this time the exit was blocked, meaning the gas had no way out. Instead, the air travelled to each of her butt cheeks as if they were balloons ready to be filled.

Just like before, the inflation of her butt also required many cycles of filling and massaging in order to get as big as her owner desired. Her asscheeks bloated into massive balls and her thighs pressed together with such force that the woman had troubles taking the hose out. Eve doubted she would be able to walk without releasing loud squeaks whenever her buttcheeks grinded against one another.

The massage and affirmations whispered into her ears were enough to put Eve back into her submissive toy state, even quicker than before. At this point, it was almost as if Eve had a switch that could make her go from human to toy in an instant.

The girl rested on top of her belly, completely in peace, waiting for her owner to decide how to customize the rest of her shape.

— What’s next?

— I guess the arms and legs — said her owner — I’m pretty sure those blimpy thighs will be awful for waddling around the house, so maybe I should give her paws to help her walk around on her fours… Maybe those of a cat…

— Nice choice! — she said — We often recommend overly inflated toys to have a quadrupedal shape.

One by one, Eve’s arms and legs were turned into thick cat legs with short, round stubs for fingers. Her flat hands and feet became exaggerated paws that squeaked whenever pressed against the floor. Her rubber joints also reshaped in a way that allowed bending in new ways that were optimal for walking on her fours.

— Show us how you walk, my shining balloon toy.

Eve happily obeyed the command and began to move her fours paws in synchrony, however her belly was so immense that she barely moved from her starting position. Instead, the cat-girl seemed to merely slide her limbs on the floor without getting anywhere. She appeared to be swimming in place, lying still on top of her round belly like a pedestal.

— Oh my — the woman chuckled — Do you want to deflate her belly a bit, mister Greg?

— Maybe I should…

However, before the woman could reallocate the air, Eve surprised everyone. She bent her hindlegs like a spring, pressed her bloated tummy against the floor, then performed a hop forward, nimble as a bunny.

She continued to move around in that interesting way, bouncing off her own belly with quick pounces, quickly adapting to that new shape as if new instincts were kicking in. Her whole body squeaked and wiggled with each pouce, causing her ass, boobs and belly to shake.

Boing… boing… boing…

Eve had a wide smile on her face, just like a happy pet playing with itself.

— She’s a smart toy — said the woman — Most toys take a while to learn their first skills.

— Well… Eve is a very intelligent girl.

“Eve?”
“Who’s Eve?”
“Girl?”
“Wait a moment!”
“What am I doing?”
“I’m not a damn toy!”

The girl recovered her human mind mid-jump and lost her balance, falling on her back. She squirmed in place, trying to turn herself up again, but just like a turtle, seemed unable to flip on her own.

“How did I let it happen to me?”

She checked her own stubby paws as if seeing them for the first time. She barely remembered when those things were transformed to begin with. Her last thought was having her butt massaged and being told how good of a toy she was… Then, almost in the blink of an eye, she wakes up as a light blue balloon cat with paws for hands.

But then, something clicks on her head.

The cat memories and the human memories merge together and Eve remembers hopping around the room like a bunny, making a fool of herself in front of her brother. She remembers being called a “smart toy” and half of her mind feels proud while the other half rejects that compliment.

— Do you like her shape, mister Greg?

— Oh, yeah — he nods — This is perfect. I don’t think I want her any bigger than this. You can put the rest in her tail.

Since Eve was already locked in that stupid position with her belly facing up, the woman took advantage to hold her tail without worrying about the cat-balloon-girl trying to run away.

The hose penetrated the tip of her tail and air was pumped inside. The appendage, which was once as thin as a human arm, grew in size until it was as thick as a leg… then as thick as a thigh… then as thick as her human torso had been before the changes.

The overstretching of her tail caused those familiar cramps to appear, and the woman had to turn off the pump and massage the tail until the pain went away. The caress, accompanied by many strong affirmations, tried to subdue Eve’s consciousness for the third time. However, the girl resisted. She didn’t fall for those sweet words and managed to keep her human mind intact throughout the process.

Whenever the pain vanished, Eve lifted her right paw to signal to the woman she was ready to be inflated again.

"let's get this over with fawt… please…"

Filling up her tail took longer than all the rest of her body combined. She required more than ten massages. That appendage was bigger than her. She could probably fit two of herself inside that tail!

She could already picture herself dragging that tail behind whenever she tried to move around… That is, if she could still walk around with that thing, which looked more like an anchor.

— Okay — the woman sighed and cleaned the sweat off her forehead — One month’s worth of air. It's all in.

Eve looked down at herself and hissed in embarrassment. her body had no traces of humanity left. She was just like any inflatable toy people could buy in a store, the only difference being that she could move.

— Hey! — Greg pointed to his sister’s head — She still has a human head.

Upon realizing that, Eve became crimson red and her cheeks burned. Her situation was even more humiliating than she initially thought. Looking down at her belly, she saw her own reflection: a human head sticking out of a transparent cat balloon body.

— Oh, don’t worry — the woman waved — We left the head for last. However, before dealing with that, we should give the toy’s rubber some time to adjust to its new shape, otherwise the form might get distorted.

— Oh… right…

— Meanwhile, follow me to the waiting room, mister Greg — she pointed to one of the many doors — I need to give you some instructions on how to properly take care of your balloon.

The two left the room, leaving Eve behind, still flipped on her back, as if she was just a random object that could be left alone.

A few minutes later, the woman and Greg came back. Eve was still lying on her back, unable to get up on her own. The tail attached to her butt was so big that, if looked from far away, it would seem as if Eve was the actual tail and the tail was her body.

In all honesty, she regretted everything. If possible, Eve would go back in time and accept the offer to do the house chores for a full year instead of going through that dehumanizing process of becoming a toy. Heck! She would accept doing the chores for two years! Walking around, cleaning the house sounded refreshing compared to barely being unable to even move in this oversized body!

— We've given it enough time to mold, so I can take these silly straps out.

One by one, the woman untied all the straps that had been squeezing her body. It caused the pressure to even out in her insides, removing a lot of the annoying tension that had been bothering Eve.

However, even as the pressure equalized, her body maintained the same shape. Eve still had exaggerated boobs, an enormous belly, a bloated ass and a tail three times her size. Her body was able to keep it's parts at different volumes as if she had been perfectly crafted to be like that all along.

The only strap left behind was the one at her neck, which separated Eve's full ballon-cat body from her uninflated human head.

— This is your toy's shape now — the woman announced — No matter how much you squeeze, bounce, press, kick, pull or push, it will always come back to this form.

— Sweet!

— Time for the last touch!

The woman changed a few settings on the computer, then picked up a different hose and brought it closer to Eve’s lips. Reluctantly, the girl opened her mouth and allowed the hose to be inserted.

As soon as her lips touched the plastic surface, her mouth fused with the hose. Her skin had become one with it, forming an airtight lock. She desperately tried to spit it out, but it was like trying to breathe with her mouth closed. Her fate was sealed.

The warm air filled her mouth with a taste of latex and both cheeks puffed out, stretching into spherical shapes that resembled a squirrel with a mouthful of nuts. When the pressure grew too big and it felt like her cheeks couldn’t stretch anymore without popping, her face pushed out into a muzzle, inflating just like any regular balloon until a third of her field vision was blocked by that rotund snout.

When that new muzzle also reached its limit, the air somehow travelled to her ears, causing the lobes to expand and acquire triangular shapes large at the base and pointy at the tip. Looking at her own reflection on it's belly, Eve saw a pair of giant cat ears sprouting from her head.

When those ears also reached a limit, the air spread all over her head, causing a feeling of hollowness and lightheadedness, as if her insides were slowly disappearing.

Her head grew in size and her skin changed to a weird purple before reaching the same light blue as the rest of her body. In addition to that, her head gained a shining translucency that revealed just how empty she was of anything but air. Even her hairs grouped together and formed sausage-like appendages very similar to the long balloons used by clowns and party magicians.

Eve was having trouble concentrating as her thoughts seemed to spin around in a hurricane of confusion. She was unable to hold any idea for more than a few instants before losing it to the mindless void forming where her brain used to be.

Cramps started to form in her head at an alarming rate as it swelled into a shape between human and cartoony feline. Everything seemed to indicate she was filled to the brim and close to an explosion. However, the woman didn’t turn off the pump, instead she increased the pressure even more!

“I’m gonna pop!”

But then, something "opened" in her ears and they started to hiss as a bout of air began to escape through it. At first Eve relaxed when that dangerously high pressure reduced… But there was something weird going on that she couldn't really point out.

Her mouth was forced into a painted, wide, silly grin that went from cheek to cheek. Her eyes became extra shiny and swollen, ganing a stupid look. Her thoughts slowed down and she felt like floating in the clouds.

Eve was relaxed...

She was too relaxed…

She was unnaturally relaxed…

Too late Eve noticed that the thing escaping her head wasn’t air, but her mind! Memories vanished one after the other and her vast pool of knowledge was erased from existence. She fought to retain whatever was left of her, but everything slipped away as her body dumped her brain away to make up space for more air.

She forgot where she was…
She forgot who she was…
Her mind became a blank canvas just waiting to be painted…
The only thing left was an unquestionable desire to smile and be played with. Everything else were just useless ideas unfit for a good living toy such as her.

Squeak!

Eve smiled.

— She looks stupid — her owner giggled happily — I love it!

---

— What are you going to call her?

— Can’t I just use her real name?

— Not a good idea. That might cause its human mind to come back too soon. You should also avoid talking about things that might trigger some of it's memories.

— What happens if I do?

— Your toy might panic and it's human mind will wake up before the right time. If that happens, your cute balloon cat will become grumpy and confused.

— I didn’t know that…

— You should also avoid using the "she" pronoun. Stick to using "it", since a toy is still an object, even if it can move and think.

— That's a lot of things to remember...

— Just to be safe, treat it like a regular living toy… or a house-cat if you feel more comfortable. The toy will accept any form of treatment you choose.

— What if I trigger her… I mean… trigger "it's" memories by accident?

— If it shows any signs of distress, just massage it's big, soft belly and call it a “good toy” until it relaxes. That never fails.

The cat balloon wiggled around happily after hearing those words.

— Wow… she… it... really likes being called that!

— I told you. Try it out yourself.

— Good balloon!

The weightless cat jumped on him, trying to hug its owner and show off all that playful affection begging to be released.

— You two will get along well.

— Did my sis… my toy... forget everything? — the owner giggled as the toy nuzzled his face and neck with a big soft muzzle.

— Its mind is completely empty. The only thing it knows is that you are its owner. You can rewrite its memory however you want. I recommend coming up with an elaborate story about how it was conceived.

— About the inflation process?

— No no… Come up with something magical and fun. It'll believe literally anything you say. Give it a happy backstory and it'll be a happy toy.

— Will this have any everlasting effects?

— Once deflated, after one month, the mind and body will come back to normal.

— Will it remember everything that happened during its time as a toy?

— Absolutely! So you better make sure to give it a great time.

— Should I bring it back here in one month for deflation?

— The deflation will happen naturally, there is no reason to come back — then she chuckled — Unless your lovely "you know what" wants to become a toy once again.

— Not sure about that, mam… It was really hard to convince my sist… my toy... the first time.

— You underestimate how good it feels to be a toy — she scratched the balloon cat behind the ears — Do you like your new form, my cute balloon?

The toy squeaked happily and pounced around, dragging that huge tail behind. The moving object was wholeheartedly enjoying its new shape and the weightlessness of its body and mind. There were no traces of the girl she once was in that empty head. Eve had become a vessel for a toy.

The large grin on her muzzle was proof enough that, whatever the toy was feeling, it had to be good.

Squeak!

One month and a few weeks later…

— C'mon, brother! — Eve kneeled and grabbed his shirt — Please!

— I'm kinda busy this week — said Greg.

— I'll do the house chores for the rest of the year! I swear! — she lowered her head all the way to the floor — I beg you!

— One year?

— Yes! One year!

— You also promise not to bully me for one year?

— Yes! I would never bully my dear brother!

— So… you'll do all the house chores and you'll stop nagging me for one year?

— Yes! Yes!

— In exchange for doing all those things, you'll… get to spend one month as my balloon toy again?

Eve nodded and smiled, with a stupid grin on her soon-not-to-be-human face.
