Valerie took the first of what would soon be many deep breaths for the afternoon. The young woman was entering what she mentally referred to as “likable mode,” where she would tone down her more… abrasive personality traits in favor of a more charismatic personality. It was a necessary evil for getting popular online, and after this newest video she was about to shoot, she was sure her popularity would shoot her up to internet stardom. Propping her phone against the wall on a table, she hit record and started filming.

“Hey everyone!” she almost sang as her face artificially lit up, “So, you’re probably wondering why I’m in my garage right now…” Valerie moved to the side for a moment, showing off the mostly empty space of the two-car garage she was in. “Wellll, maybe you’ll understand when I pull out this!”

From off camera, she wheeled a red cylindrical object with a motor and a hose stemming from it. You horny little freaks probably already know what it was, but for those who don’t, it was an air compressor.

“Thaaaat’s right! It’s time for the Inflation Across the Nation challenge!” Val was referring to the latest online trend making waves across social media. The gist was that all the hottest e-girls were sticking air hoses in their mouths to inflate their boobs up a few cup sizes, then showing off the results. It was started to spread awareness about something, but at this point everyone had forgotten why it had started. Valerie certainly didn’t mention or even remember the real purpose for this oddly horny trend; all she really cared about was more clout.

Wasting no more time, Valerie popped the airhose into her mouth (don’t worry, she sanitized it first). Kicking the machine on, it began to whir as air rushed out of it and into Valerie. She made sure to wear the lowest cut top she could find for filming to really show the effects of the inflation. After a few moments of inactivity, a bit of movement could be seen on her boobs. Indeed, the air seemed to be going right to them, just as planned. The soft mounds started to overflow from her top like a soft drink fizzing over the rim of a glass. However, unlike how normal breasts would be pulled down by gravity, hers began to rise upwards with a delightfully jiggly buoyancy. Valerie smirked at how enticing her chest must look to the haplessly horny followers she had accrued. Just a few more seconds would be fine for the video, then she could wrap things up and-

Suddenly, Valerie heard the door open! Her head swiveled to the side to see who entered.

“Valerie honey, your laundry is-” intoned her mother, Janet. However, her greeting was interrupted by the sight before her.

After an awkward second, Janet’s face formed a suppressed smile which she tried to cover with her hand. Yanking the hose out of her mouth, Valerie’s face went beet-red.

“Oh my god, Mom! You’re ruining my video!”

“It’s not a naughty video, is it?” Janet’s smile remained as she teased her daughter.

Valerie exhaled like a steam vent turning on. “No! It’s for a new trend where you make your boobs bigger with an airhose!”

“Ah, youth…” Janet idly mused. She was brought back to her own college days, where a very similar trend caught on at her campus. Many memories of stretched shirts, ogling boys, accidental lift-offs… It seemed history did tend to rhyme after all.

“Ugh, now I need to wait for all this air to come out to do another take!” Valerie pouted, walking over to her phone as her newly enhanced breasts bobbed and jiggled.

“I could always do it for your viewers,” Janet helpfully offered. “After all, your comments always seem to like when I show up in one of your videos!”

Valerie sighed as she adjusted her phone. “That’s because they’re a bunch of weird simps with mommy issues…”

Janet picked up the hose lying on the ground. “In that case, wouldn’t it get you more views if they saw some really big knockers?” She playfully winked and stuck her tongue out, feeling younger already.

Turning back to her mom, Val seemed to take that last part personally. “What do you mean? Mine are plenty big!”

“Well, yours are okay Dearie, but…” Janet nearly stopped herself from finishing, but continued anyway, “I’m afraid your mother still has you beat in that department.”

“Mine are bigger now,” replied Valerie, approaching her mom.

“Well, they certainly won’t be in a second!” With a playful flourish, Janet stuck the airhose in her mouth.

“We’ll see about that!” Valerie shot back. Luckily, for the sake of this story making sense, this particular air compressor had two hoses. Maybe it was so it could fill up two tires at once, idk.

The two women’s breasts began to inflate in a heated battle of the boobs. Although Valerie had a head start, Janet was filling up fast due to her natural affinity for such silly cartoonish hijinks. It seemed that years of wacky hijinks had tempered her body for shenanigans. Like a couple of rubber balloons, their milky orbs began reflected light in a way that nearly made them shine.

Valerie glared at her mother with a venomous envy. She wasn’t going to let her dumb mom beat her at being sexier! Janet, meanwhile, just smiled with her eyes. The spirit of friendly competition was in her… as well as her pride as the busty MILF on the block.

Boobs popped out of shirts, strained against clothing, and grew to frankly unnatural sizes as the contest continued. However, that wasn’t the only thing happening. Both women felt the sensation of the air affecting them in other ways: their bellies began to bloat, thighs got thicker, and arms got stiffer. Despite this, neither was willing to admit defeat. A growl from Val and a challenging hum from Janet served as wordless agreements that they would continue.

As the ridiculous game of chicken went on, they only got more and more bloated. Their breasts were getting close to their limits, but every little bit of air counted. Really feeling the internal pressure, Valerie looked down at the airhose in consideration of shutting it off. However, to her surprise, it was farther away than before. Moments later, she felt her feet leave the ground as she began floating off it! Janet experienced the same at nearly the same time.

At this point, Valerie was ready to throw in the towel. She reached for the hose, but found that she couldn’t quite reach it. Even her limbs had filled with air at this point, stiffening them to the point that she couldn’t even reach down without rotating her entire body..

“Hmmm?! Hmmph nmmnpph!” she complained with the hose still filling her mouth.

“Hmm mnnph mmm~?” Janet replied.

Valerie couldn’t stand the smugness in her mother’s tone. It wasn’t just about boobs anymore; this was about proving that she could outlast her mom in even the silliest of competitions. An uncharacteristic sense of generational pride came over her and spurred her to endure more.

And so the inflation continued. Centers of mass shifted while heels helplessly wiggled in the air. Their torsos expanded outward, defying the normal hourglass shape and replacing it with a soft spherical form. This roundness was all consuming, subsuming their limbs into nothing but lumps on the balloon-like masses of their bodies. Tightened, shiny skin poked out from clothes that wrestled to cover it. Soon the two women were bumping and bouncing off each other as two colliding parade floats would do. Available space in the garage lessened and lessened, and soon the big balloons were feeling the walls and ceiling of the enclosed space.

Some resolve had wavered in their hearts, but upon looking in each other's eyes, each was steeled. However, room was quickly becoming limited within the limited space of the garage. External pressure was starting to matter as much as internal pressure as they pressed into the physical constraints of their space, until suddenly-

Creeeaaaaaak

Janet and Valerie gave each other confused looks. This sounded different from the creaking of their overstretched and rubbery skin.

THMMM!

Suddenly, the whole roof of the garage lifted up from the force of the balloons underneath! The weight of the roof was enough to keep Janet and Valerie from floating off into the stratosphere, leaving them hovering above the garage.

“Mmmph! Hmm mmph mmmm…” Janet whimpered. Thinking of how much repairs would cost for that, she actually lost her smug coolness for a moment.

“Mmm! Hrrmmm mmph mmmm!” Valerie’s murmurs were much more urgent. She looked down at the neighborhood and noticed all the people out and about in the suburb were staring right at the two huge balloons stuck under the floating roof! More and more neighbors stepped outside to see the sight of the two overinflated women. It seemed like everyone was ogling the two living balloons.

Janet glanced downward at their next door neighbors’ horrified faces. The annoying wealthy couple was sure to report the sight of Janet’s barely concealed ass to the homeowners association! She groaned at the thought.

Valerie, meanwhile, couldn’t help but notice that the cute guy living across the street was staring directly at her. With her yellow top looking more like a painted on decal than an piece of clothing, she felt completely naked in front of his venturing gaze. With her skin getting even redder, Valerie thought she might be more full of embarrassment than air.

…Then again, there was a lot of air.

The pressure was starting to get too intense to bear, and even Janet was feeling like she was reaching her physical limit. Still, they grew and grew and grew. Their skin stretched more, all the way to the point of being stretched so thin that it could be seen through! The two overfilled balloons groaned and strained and stretched and creaked to keep it all in, moaning from the pressure, feeling utter embarrassment from the onlookers, feeling the weight of the roof on top of them, yet still bearing unyielding egos that would not give in to-

POP!-POP!

THUD!!!

In the blink of an eye, the balloons disappeared, and the roof of the garage fell back into place. Small flesh tone scraps rained down to the ground as members of the neighborhood shrugged and went back inside. Direct neighbors shook their heads and crossed their arms as they watched bits of the two women litter their immaculately kept lawns. Amidst the chaos, two shreds of pink gently floated down next to each other.

Two pairs of lips fluttered down onto the driveway, one pouting and the other slightly curled upward in a grin.

“...You popped first,” Janet’s lips sang out.

“NO! I HEARD YOU BEFORE I POPPED!” came the furious reply from Valerie’s mouth.

“It’s ok to not be as sturdy as your mom, Dear,” teased Janet.

“I WON AND YOU KNOW IT!”

“No no no, you see I was still-”

“DON’T PRETEND LIKE I DIDN’T WIN-”

“You just aren’t as resilient as me yet-”

And so, the two continued to talk over each other and argue well into the evening in what would continue to be one of the most hotly contested issues in their household for years to come.
