The Set Up

"What is this thing? A vacuum cleaner?"

Claudia shook her head in confusion, as both her and Emily approached the center of the dark basketball court. 

"Is this some kinda joke?!? 

Show yourself and tell us what you want, i got no time to waste on this bullshit..." 

Emily added, quite irritated on the situation, since both girls awaited at the center of the big court, in front of a double end vintage vacuum cleaner with two thick purple hoses coming out of its outputs, trying to understand who was behind this mysterious note they had received earlier and asked for their urgent presence at the gym at noon... 

Then with a loud noise, the big gym lights went on and two other girls started walking towards Claudia and Emily at the center of the court.
 
"Jeanne! Mariah! It's you guys! What is this all about already!" 

Emily almost yelled at the approaching girls who were almost there by now, the grinning quite visible on their faces...

"Glad you could make it girls! We are in need of some help! We have two huge surprise blimps to inflate for the annual parade..."

Jeanne said, just when she stopped in front of Emily and picked the one hose from the floor...

"That's true you know, we couldn't say more in the note cause we like to keep it a secret, since such blimps will be so special this year..." 

Mariah added to Jeanne's word, as she picked up the other hose, and both girls looked at each other with a conspirative grin...

"Wow, sounds cool!" 

Claudia yelled in excitement, before approaching, even closer to Mariah...

"Cool indeed, Claudia! But wait a minute, i see the vacuum, where are the blimps? What are we supposed to help in infl-MPMHMPHHMPHPHH!!!!!" 

Emily tried to respond, before she was violently cut off from the thick hose being forcefully shoved into her mouth from Jeanne's hand, as Claudia had the same fate silmuntaneously, as Mariah shoved the other thick hose into Claudia's mouth, again with huge force and out of the complete blue.

Suddenly the vacuum was switched ON with a loud mechanical noise, instantly springing to life and it was obvious that it was in reverse, since almost instantly both Claudia's and Emily's cheeks puffed out and bloated with the strong amounts of air that had hit their mouths. 

Both poor girls, were ambushed and were inflating like balloons as huge amounts of mechanically pressurized air, started traveling through the hose and down their throats into their fit teen bodies, bloating them outwards all over like blimps, making every attempt of them to move quite comical as their limbs were spread out from the pressure inflating them too, hissing sounds and loud moaning of distress filling out the entire court as Jeanne's and Mariah's wicked plan had seemed to be successfully working...

"Oh silly Claudia, silly Emily...YOU girls ARE the blimps, don't you get it yet? You'll be the biggest surprises the parade has ever seen, and we'll get all the credit for it!!! High five Jeanne!!!" 

Mariah yelled in excitement, as they cheered and yelled hugging and jumping in joy with Jeanne, watching poor Claudia and Emily, achieving cartoonishly over proportioned sizes and shapes within each passing second. Both girls had over inflated spherically, all their limbs puffed out beyond recognition as their mouths were stuck to the hoses downwards, and their gigantic behinds floating higher into the gym's air, rounder and rounder, bigger and bigger almost 10 feet in diameter each yet...

The most comical parts of them, were their heads, with inflated cheeks the sizes of volleyballs, Emily quite bigger than Claudia already since she was on the most powerful output of the vacuum, their size difference quite visible already since Emily's inflation was very powerful in speed and rate, and her eyes were already bulging like balloons out of her sockets, making her look all puffy pressurized and ridiculous...

"Better get them outside, what's in store for them, could not even fit in gym three times the size of this one...." 

Jeanne yelled and cheered, as both her and Mariah tried to move the inflating blimp girls out in the open, through the only - not for long- fitting door of the gym, out in the open, where their parade plan would achieve it's unlimited grandeur at last...
