"It’s not going to work."

"Come on out, I bet you look great," Lynn pleaded.

I stepped out from behind the curtain where I had changed into my costume.  Not my superheroine costume, my Halloween costume.  Sigh.

Lynn sat on the sofa waiting for me.  She had her hiking booted feet propped up on the coffee table.  Tight cargo shorts and a tight tank top with sunglasses pulled low on her nose and her now-dyed-brown hair back in a braid. She was practicing spinning her pistols in opposite directions.  She looked up at me, "Whoa."

"Yep, that’s what I thought, forget it I'm staying home to eat ice cream-"

"No way! You look amazing!"

I looked down at myself; "This is what I get for shopping for a costume the day before Halloween, the leftovers."

Lynn bounded to her feet, "You know why its leftover, because no one really has the body to wear that, so no one buys it.  You, however, look mahvelous darling."

I knew I was blushing and I hated it.  I stared down my body.  I had fishnet stockings on, which, combined with my height and the high heels I had on, made my legs look a mile long.  Over the stockings, I had a very tight, very brief, bright pink one-piece with a puffy rabbit tail on the seat.  Cuffs and a collar around my arms and neck and a pair of fluffy ears sticking straight up from my head finished my bunny outfit.  I put my hands on my hips, "I actually feel less dressed than if I just walked out in lingerie."

"At a sorority Halloween party I expect someone will,” she nodded at my costume, "how much extra do you have in there?"

"Room or gas?"

She laughed, "Either."

I pressed my hands flat on my midriff, "Not a spare centimeter of room in this outfit, I couldn't fit my costume under it, and only enough gas to give my powers a boost."  It was true, I only had a couple of inches of pneumatic enhancement in my chest and below my waist, but I had managed to keep my tummy flat as a board.  I grinned as I started to feel better about my appearance.

"Do you have enough juice to get us down, or should we take the elevator?"

I looked up at the skylight, two stories above us, open to the mild autumn evening and I held my arms out, "C'mon."

Lynn holstered her pistols, grabbed onto me and I launched us into the air, soaring up out of the skylight onto the roof of our secret base.  Then with Lynn clutching me for dear life, I leapt off the top of the abandoned water tower, dropping the nine stories or so to the ground, where I landed perfectly on my high heels.  Setting my roommate on her feet, I pulled the remote control for our underground garage from my purse.  Moments later, we were zipping along in my MG to a perfectly normal Halloween party.  Hey I was a superheroine right?  What could possibly go wrong?

When we stepped onto the porch at Delta house the door opened, and my heart leapt into my throat.  Standing on the porch, not two feet from me was the familiar magicienne's costume of Expandra.  My right fist lashed out in a punch, catching her right on the point of her jaw, the supervillianess collapsing with one punch like a sack of potatoes.  

Lynn goggled at me, "Have you flipped?"

I goggled back at my teammate, "But, she...bad!" I sputtered, "You weren't there for the fight with Expandra."

Lynn giggled, "Okay slugger, but that's not Expandra, you just clobbered some cheerleader in a magicienne costume."

"Aw hell,” Oh boy, "But, she's...blonde."

"And while I agree that's a perfectly good reason to deck someone, nevertheless you'll forgive me if I am relieved that I coloured my hair just in time."  Lynn pulled the unconscious woman up and inside the partying sorority house, "Let's just hope she doesn't remember you when she comes to.  C'mon, let's lose ourselves in the crowd."

I looked at the unconscious girl as we left her slumped in a chair in the foyer, "Sorry."

We pushed through the hallway to the large common rooms of the sorority house, packed with a large number of our fellow students doing the different things, drinking, talking, dancing and the like, that make up parties.  By the punch bowl I got my second shock of the evening.  Standing there, making small talk with a pirate, was an attractive, athletic young woman, wearing a white one-piece, black boots, a cape, mask and utility belt.  

"She's-"

"Dressed like Airtankgirl," Lynn finished.  "Look, there's another one too, ready for action," she pointed.

I saw across the room there was another young woman dressed identically, except that what should have been her slim midriff bulged full and soft in her tight spandex costume, cinching her utility belt around her padded waist.

"Oh my gosh," I breathed, "Does my costume make my hips look that big?"

Lynn laughed, "Hang out here, I'll try and score us some snacks.  Gangway, fridge Raider coming through!"

Upstairs, unknown to the party below, three college girls sat more than a little drunkenly, huddled around the pentacle chalked on the floor of their darkened room.

"Sisters, prepare yourselves...hic."

"This is silly,” one of them, a brunette in a black latex catsuit and corset, said.

"Silence infidel," said their leader, a very attractive blonde dressed in a black one-piece that laced across her bust, and a pointy hat to indicate her witchiness.  Below the curve of her ample bust, her belly swelled full and round in her costume, "C'mon Selene, you said you'd help, look, Diana's ready," She nodded at their third member, dressed in a Wonder Woman costume, but unlike the Amazonian superheroine, this Wonder Woman sported a midsection just as round and stuffed as her witchy friend.

The plump Amazon giggled, patting her swollen belly, "Don't think I'll be able to fit in my invisible jet."

The witch held out a pillow to Selene, who unfastened her corset, opened her latex bodysuit, and stuffed the pillow into it, zipping it up over her bulging waistline with difficulty.

The trio of tipsy, fattened sorority girls chanted in made-up Latin and broken elfish and bad klingon and whatever else sounded right at the time.

"Faelina, Demon of the Waistline, we summon you..."

The witch knelt over the candles and the pentacle, her stuffed belly bulging over her bare thighs.  When the candles blew out, there was still sufficient light from the streetlamps to illuminate the room, if imperfectly.

"Uh, Tabitha,” the bulging Amazon asked, "Did you blow out the candles?"

Tabitha the witch was holding her arms out and mumbling mystical gibberish with her eyes closed.  Her two friends watched her in amazement.  Suddenly she stopped, opened her eyes and giggled at her friends, "What?"

Selene sighed in relief, "Well you just looked so...intense, like you were really getting into it."

The round witch giggled again, "It was just something I saw on 'Buffy'...huh," She interrupted herself, looking down.

Her two friends lowered their gaze to follow hers.  All three of them were staring at the bulging cleavage of Tabitha's bust, now straining against the laces of her costume.

"Tabby...?"

She put her hands against the sides of her now large breasts, "I feel funny,” With an audible hiss, Tabitha's breasts began to swell, pumping up inside her costume, first straining, then bulging against the laces up her front.

"Tabby what's happening to you, you're getting bigger!"

Their inflating friend put her hands on the tops of her ballooning breasts, "Uh, I.... I’m blowing up!"

Selene got clumsily to her feet, her pillow-stuffed belly in her way.  She unzipped her latex bodysuit to pull the pillow out and slim herself down again, but when she did, the tight bodysuit spread open over the taut dome that was now her bulging belly.

"Diane...look at me, I've become a blimp!"

The bloated Wonder Woman pressed her hands on her fattened belly, knowing that her own body had bloated up full and round like her friends.  Additionally she could feel the top of her costume growing tighter as her breasts began to swell with a hiss.

"Oh we're blown up like balloons!  We're getting so fat, its not possible, people don't just inflate like this!  What's happening to us?"

"Well, I should say I am."

The three swelling sorority girls all stopped cold at the new voice.  Cultured and feminine, yet also deep and menacing.  Not human.

In a fashion no human could ever perform, the newcomer was perched on the top of the back of one of the desk chairs, The beautiful young woman brushed her purple hair back from her face, over the two large, curving ram horns, and smiled a big friendly smile with a mouthful of teeth that looked like a cross between a Great White shark and a combine thresher.

She stepped gracefully from her perch, her curvy, well-endowed figure, filling her tight, shiny purple bodysuit like an overripe fruit.  Her pointed tail trailing along her high heels wasn't lost on her victims.  

"Baby, when you summon a creature such as myself, you should expect to blow up some.  Really," She knelt in the center of them, pressing one hand on Samantha's full roundness, and one on Diane's blimped belly, while her tail pressed on Selene's swollen belly where it bulged out of her catsuit, "What did you expect was going to happen.  Oh yes," she purred, "You three are getting nice and fat."  While caressing the swollen girls, the demon's waistline bulged out noticeably in her tight purple outfit.  Her sleek, shapely middle swelled into a soft round bulge.

She stood, patting her bloated tummy, "Mmmm and apparently I'm going to get pretty full myself here if I'm not careful," She concentrated, her waist shrinking back down to her normal shapeliness.  She patted her now flat tummy, "In due time."  Faelina, the Demon of the Waistline stepped over the inflated girls and out into the rest of the world.

By the time Lynn reached me with a plate of snacks she had to elbow through a circle of a half dozen men surrounding me, trapping me against the punch bowl.

"Hiya!"  I said brightly.

Lynn looked at me, then at the guys around me, "Whew I'm glad I got here before you started drinking.  Remember that last party where you had some punch before you could mention your allergy to alcohol, and you started vomiting and convulsing..." She grinned evilly as the male hunting pack slunk away for prey that was weak or injured.

"Gee thanks, I didn't get you anything."

Lynn pushed the plate of snacks at me, "Eat this, you shouldn't drink on an empty stomach, and you do happen to be one of the world's great lightweight drinkers.  You get tipsy off vanilla."

"I do not...hic."

"Second, they were creeps.  Third I did you a favor," She took me by the shoulders and aimed me at a couch where, reclining in street clothing with a big gift wrapped box next to him, was my favorite cabbie, Nick, "Now eat, it'll sober you up."

"I don't think there's room for me and scooby snacks in this outfit," I complained, but ate anyway.  It only seemed like a moment and then the plate was empty, and my head did feel clearer.  I walked over to Nick and stood over him as he recognized me, his face lighting up.

"Hi there."

"Hi yourself," I pursed my lips and winked as I did when thinking, then pointed at the box, "I should beware you?"

He grinned-oh, he had a good smile-and moved the box to the floor, opening a spot on the couch for me, and nodded, "Greeks bearing gifts, you're smart."

I sat down next to him, "Yeah, I only look stupid."

"I think you look great."

We passed a lovely and terrifying ten minutes in small talk and flirting, which I won't bore anyone else with.  Naturally since nothing in my life can be easy, the moment of mundanity evaporated with the audible, and familiar creak of tight clothing getting tighter.  My clothing, in fact.

Nick looked around, "What was that, it sounded like someone rubbing a balloon the wrong way?"

I blushed, "Would you excuse me for a moment?"  I stood up, feeling the extra fullness of my bottom as it stretched out my bunny costume.  I got up and walked back into the partying crowd; very self-conscious of the extra inches I had spread out in my rear.  I hope Nick didn't notice how wide I was when I left him.

Searching for my roommate in the crowd I was jostled up against a lovely young woman, dressed in a magicienne's costume, I tried to avoid her, but the push of the crowd had us pressed against each other, chest to chest.  

"Uh, hi,"  I tried.

She smiled back, "Hello."

"Sorry about that, back there on the porch."

She frowned, "Sorry, I don't follow?"

"When I hit you?  I thought you were someone else."

Now she laughed, "I think you still do, no one has hit me since I got here," It was true, I couldn't see a bruise on her jaw, "And while I am looking for a bunny, you're a little larger than my little fella.  So if you'll excuse me, I'm a little pressed for time, oof, and space."  She worked away from me, and I emerged from the crowd to find Lynn near the salad tray feeding a carrot to a little gray rabbit.

"Hey, its he just adorable?" Lynn said as the rabbit blinked at me.

"We've got trouble."

"Who'd you hit now?"

"No, its me, I'm swelling."  I watched Lynn look me over, and her confusion at finding nothing out of place, "Behind me," I sighed and turned to prove it.

I heard her gasp along with an other creak of my costume as my bottom plumped out another couple of inches, "Manda, your butt is getting fat!"

"Thanks faithful sidekick, c'mon help me get out of here so I can figure out what's going on."

"Gandalf!  Naughty bunny!"  The magicienne I had just spoken to scooped up the rodent that Lynn had been feeding.  While she petted the rabbit's head, I heard another creak of strained clothing, only this time it wasn't coming from me, it came from the magicienne as her hips spread out and filled out her costume.

Looking at her face I could tell she was aware of it, "Uh, c'mon Gandalf, we need to get moving,” She took off her top hat, dropped the rabbit in it, and set the whole thing on her head.

I lunged forward, grabbing her wrist and twisting it into a lock.  Lynn goggled at me, "What are you, just going to punch out everyone dressed-"

"It's her!  Its really Expandra!"

The magicienne, stared at me for a moment, trapped by my hold on her, then her eyes narrowed, and a vicious smile showed on her full lips.

"I even think you're going to use your powers and I'll break your arm, you actually do use them and I might rip it off."

Expandra relaxed in my grasp, "Look Airtankgirl, I didn't come here to fight."

"Who robs a sorority party?"  I asked.

"I'm not robbing the place, I'm contributing.  I'm an alumni."

"'K, I didn't see that coming," Lynn said.

"It's true, my little sister Tabitha is a Delta, and I contribute to help their events.  I probably paid for those canapés that your friend has been demolishing."

"What?" Lynn mumbled through a mouthful of canapé.

I hated to admit it, but I believed her.

Expandra nodded at my hold on her, "If you could just manage not to break my arm, and maybe let the air out of me, I won't give you any trouble, I promise."

I let go of her, she rubbed her wrist, "Thanks, now, my figure please?"  

"Huh?"

She rubbed her wide, inflated hips, "Hello, I'm a little pumped up here.  If you could just deflate me back to normal-"

"Hang on, I thought you had pumped me up!"  I half turned, displaying my inflated rear, bulging out of the seat of my costume.

"So whatever is causing you two to swell up..." Lynn mused.

"It isn't me!" Expandra and I said in unison.

At that moment, something truly strange happened.  I felt a small pressure inside me, and felt my stomach bulge outwards a few inches, my costume stretching tightly across my new tummy.  I put my hands to my waist, hoping to tug my costume enough to give me a little extra breathing room.  At exactly the same moment, both Expandra and Lynn, with little hisses of expansion and the creaks of tightening clothing, swelled up a few inches in the waist as well, both girls thumbing their tight waistbands in an effort to gain more room in their straining costumes.  Lynn's gunbelt was drawn snug around her rounded middle while Expandra sleek costume was noticeably bulging in front against her cummerbund.  She rubbed her fattened tummy thoughtfully.

The truly strange thing was that half of the conversation in the party ceased instantly, as every woman present stopped talking and fiddled with the tightening waistbands of their costumes as the belly of every single female there bloated out a few inches at exactly the same time.

"A...Airtankgirl?"  Lynn recovered from almost using my name, looking down at herself, with her hands on her bulging middle, in exactly the same pose every woman there had simultaneously adopted.

I looked across the room, my gaze stopping at the top of the stairs.  I nudged Lynn and Expandra, who followed my eyes.

The Demon was in the house.  Somehow I knew that the lovely redhead with the voluptuous figure straining her tight purple outfit at every curve was the cause of our mass expansion.  Of course the horns and tail sorta helped me figure it out as well.  The Demon stepped past a college girl with short red hair dressed in a leopard print one-piece with ears and a tail.  The leopard girl was prodding her stomach where it bulged against the white underbelly of her costume.  As the Demon passed her, with a hissing and creaks her slightly swollen belly began to expand under her hands, her slender figure bloating and bulging in her costume.

"Wha...what's happening to me?"

"Josie...you're blowing up like a balloon!"

Her waist was growing wide and round, while her breasts started to puff up, bulging up in the front of her costume.  The spots of her leopard print one-piece were spreading further apart as her inflating body stretched the costume out wider and tighter.

The Demon grinned, obviously enjoying the inflating woman's plight.  Given the Demons' tight costume, it was impossible not to notice that her own flat belly was bulking up, puffing out.  Belly Demon spread her talented fingers on the bulge of her own belly, sighing happily.

The three of us stood watching for a moment, "So I suppose we have to take her?"  Lynn asked.

"Yep," I said.

"I'm in," Expandra said.  Lynn and I looked at her, "My sister's room is up those stairs," she explained to our questioning looks, "Besides," She patted the bulge in her shiny black briefs, "We better do something before she makes us any fatter."

I looked over at our new ally, "I like the jacket,"  Expandra had added a short dinner jacket and a brief vest to give her a more traditional magicienne's costume.

"Thanks, I didn't have anyplace to put my keys in my old costume."

"Is it designer?"

"Of course.  Ramon over at 'A Shiner You', I have all my costumes done there."

"Thanks for the tip, it’s hard to find things that fit in our business."

"And size."

Lynn produced our masks from a pocket.  

I settled mine on, "I'm not pumped up enough,"  I said, "I need more air."

Expandra looked around us at the crowd of men that were either ogling the shapely demon, or ogling their newly rounded girlfriends.  She pulled her arms through the air as if gathering something invisible.  All around us, partygoers were collapsing with a sigh, becoming unconsciousness as Expandra snatched the air from their lungs.

Beside me, the beautiful and shapely, if slightly swollen currently, magicienne spread her long legs for better balance.  Her bulging tummy swelled up in her briefs, the stretch satin creaking as it bulged with her inflating belly. Her bottom, puffed up full and round, plumping out around the seat of her briefs, her wide bottom filling and spreading out from her briefs like a thong.  Her hips fattened up, stretching the briefs and stockings alike as she widened out.      Expandra's breasts filled up her blouse, pushing, then straining, then bursting the buttons off her blouse as her chest overdeveloped, overfilling her black bra.  Her breasts grew before her and out to her sides as well, tenting the too-small blouse where it was still tucked into her cummerbund.

She waddled as her center of gravity shifted as she inflated.  She cradled and patted her stomach as she grew rounder and fatter, "Ugh, something's wrong...I'm getting too big!"

"Its the women...you're sucking in their inflated bellies, they're all getting skinny again!"

Expandra grunted as her inflating belly pushed her hands apart on the shiny black expanse of her midsection, "Great, but I'm becoming a blimp here, if I get much fatter, I might not be much help.  This is already the biggest I've ever been."

"Expandra, hit me with your bloating attack!"

The Demon was now totally engrossed with the three of us, forgetting the lesser mortals.  She licked her lips as Expandra blimped up; the Demon's hips started spreading out wide and full, drawing the infernal material of her outfit tighter around her bulging curves.

"I'll buy you some time,"  Bubbles said, taking a step towards the wide-hipped, tubby, demon.  She jerked the two HK USPs out of her costumes holsters and leveled them at the demon.

I was just opening my mouth to ask her what she planned on doing with those when the twin roar of the .40 cal pistols cut me off.  A constant stream of empty shell casings flew from each pistol as she rapid fired the magazines dry.  Knowing Lynn, I don't know what that surprised me.

Then I suddenly felt my bunny costume tighten around me.  I tried to look down at my belly as I felt it expanding, but my view was blocked my large fullness of my chest.  Apparently my costume was so tight that it was forcing the air Expandra was pumping into me into paths of least resistance.  My breasts bulged up hugely, my cleavage almost touching my chin.  

My hands shot behind me as my rear pumped up large and round, spreading my bottom out around the fluffy tail of my costume.  Apparently I was spreading out and filling up up top and down below.  My hips fattened up, growing wide and full, with my long legs plumpening and swelling up along their length, my fattening thighs pressed together as I inflated.

Within the super-tight bunny suit, my belly bulged out some, a noticeable amount, but not enough to really mark me as fat, just a little bloated.  I certainly didn't have the figure for this outfit anymore; oh my butt was getting so fat!  On the plus side, I could feel my body grow stronger as well.

Expandra was looking relieved as she lost volume to me.  Her body was still bloated with air, her costume stretched comically over her swollen figure, but while still fat, she didn't look nearly as ungainly as she had a few moments ago.

A silence as the slides on Lynn's pistols locked back.  There was no measurable effect on the Demon from the gunfire, though the Demon's breasts seemed to be growing fuller and rounder as she watched me blow up to my heroic proportions.  We all saw the clump of jacketed slugs stopped on her big pillowy chest.  

"Nice grouping," Expandra offered.

The Demon lashed her tail around one wide hip, the point catching Lynn right in the navel.

"Bubbles!" I shrieked, certain that the pointed tail would eviscerate her.

Lynn gasped as the tail punctured her belly button, then, surprised, she whispered, "Oh thank heaven, it didn't hurt."

The Demon put her hands on the bulge of her tummy and pressed down, the roundness of her belly flattening under her hands...

...While Lynn gasped again as her stomach bulged out roundly from under her top, and strained the waistband of her shorts...

...The talented fingers squeezed her fat hips down to their original luscious curves...

...While Lynn's hips spread out wide, rounding and fattening like her belly...

"Uhhh, Airtankgirl...she's making me get so fat...” Lynn cradled her new full tight, bloated belly, "Ohhh, I'm getting so full...” She moaned.

The Demon snaked her tail out of Lynn's big round belly, allowing my roommate to collapse on the ground, holding her bloated body protectively.

"You fiend, if you've hurt her..."

The demon laughed throatily at me, "Hurt her?  I think she likes being nice and stuffed.  How about you two,"  She stepped closer, over my helpless roommate,"  You both look pretty nice and full, but I bet you could still plump up nicely, what?"  Her voice was very deep, inhumanly deep, yet still feminine, compelling actually, seductive-

My ears popped as Expandra tried her vacuum attack on the Demon, startling me out of the demonic glamour.  The Demon lost the extra girth of her inflated bustline while Expandra's waistline swelled out enough to finally pop her cummerbund off her bloated body.  

"That would have been cute if I breathed,” the Demon said as she reached for me.

I grabbed her arm and turned, using my wide inflated hips to throw her over me and into the wall, where she hit with a window rattling 'THUD'.  I was on her in a flash using the super strength in my exaggerated inflated figure to pummel her with both fists.  I was impressed despite myself, I was ninja, I was all over her, the piledriver force of my blow landing on her as I chose, bypassing her defenses as if there weren't there.  

Then I realized that she wasn't defending herself, and rather than crying out from the beating I was giving her, she was giggling.  Yep, not even like an evil-master-of-the-world laugh, but a very girlish, if demonic, giggle.

A quick twist of some demon-fu and I found myself beneath the voluptuous purple fiend.  One hand pinned my wrists together against my bulging bustline while she felt the inflated swell of my belly with her hands, "Mmmm yes, plenty more room in you to fill up."

Meanwhile Expandra looked on helplessly.  She was still inflated enough to bloat the demon up big enough to make her an awkward, fat target for me, but Expandra wanted a definitive blow struck.  In a corner of the room, she found her weapon.  Every good party has to have lots of balloons, and those balloons require helium.

The magicienne threw the air she was stuffed with at the Demon, so above me, I saw the look of surprise and.delight, as the Demon began to inflate from Expandra.  Her purple tights bulged full and tight over her bloating belly, while her breasts swelled up inside her top like two big balloons, making the material creak and groan.  I could feel her belly swelling, getting fatter, pressing against me beneath her.  Her expanding girth was growing wide and round as she blimped up.

Now sleek and lithe once again, Expandra vaulted the sofa over to the helium tank.  She stuffed the hose in her mouth, spun the valve wide, feeling the lighter than air gas flood into her, causing her shapely curves to bloat out once again as she inflated herself.  But this time she opened the power to throw the gas filling her into the Demon, and held it open.  The gas hissed from the tank, and through Expandra, not plumping her up any more, but having major effects on the Demon.

The demon's violet slit pupil eyes got big and round, with her body following.  Her figure blew up fast and full, like a life raft in tights.  In moments her waist had expanded past her full hips, making her torso more egg-shaped as she turned into a blimp.  
Her talented hands grasped and petted her ballooning body while she closed her eyes and...purred.
    The hiss of the helium tank died under Expandra's hand as it ran dry.  The gas lifted the non-blimped demon off of me, giving her just enough buoyancy that her high heels only touched the floor at the toes.

"Well, thank you very much,” she murmured, apparently pleased with her new size, her voice now taking on a funny, high-pitched quality to go over her demonic resonance, "But I didn't get you anything.  Oh I know...I've plenty to go around, and round you will be."

That barbed tail lashed out again, fast as a snake, the barb catching the only slightly plump Expandra tight in the navel.  The magicienne gasped as she saw what was about to happen, with her helpless to do anything about it.

The Demon squeezed down on her ballooned stomach, while Expandra began to fatten and swell with the helium that she had just pumped into the Demon.  Expandra grew wide, then fat, then bloated, then her costume began to creak as her figure became distended, every curve stuffed full of helium from ankle to chin.  She pressed her hands to her inflating body as it rose like bread dough, the bulging, full curves of her bloated figure, soft and plush under her hands.

As the now super-bloated Expandra began to float, her body was swollen up so that her arms were absorbed by her inflated torso to the elbows, and her legs had disappeared to the knees from her ballooned belly.  She clutched her huge round belly; she pulled against the Demon's tail, which came free from her big stomach with a 'pop'.  The Demon smiled at the bobbing, bouncing parade float that Expandra had become.  Despite the volume of gas she'd pumped into Expandra, the Demon was still hugely bloated, about on a size with her victim.  She had only used half the helium on blowing up Expandra.  I had a good idea where the rest was going.

I hate being right.  

The pointed tail snapped out at me.  Given how fat the demon was, still bloated with half a tank of helium, she couldn't attack facing forward very well, her tail had too much of her inflated girth to get around.  Instead she attacked with her back to me.  Her aim was still good though, the point of her tail slammed right through my invulnerability, and I immediately felt the helium flowing from her into me.  Lynn was right, there was no pain, in fact I was surprised at it was exactly the opposite.  My knees went shaky and my vision blurred from the intense pleasure filling me.

  My belly grew fat and round, filling up my already straining costume until my bulging waist burst through the seams, allowing my big bare belly to expand freely without the confines of my clothing.  My waist was already swollen out to my hips, my torso was becoming round.  I only had a moment before I was blown up like Expandra, a helpless parade float of a superheroine.

"Psst!"  I looked down, still couldn't see past my overinflated bouncing breasts, looked sideways and saw Bubbles on the floor next to me, one hand supporting her bloated body on the hearth of the fireplace, the other raised towards me as if to give me something.  Or receive something.

"The tail!"  She hissed, "Before you're too fat to move!"

I grabbed the tail, my super strength pulling it free of me with a 'pop'.  I handed the tail to Bubbles...

...Who jammed the point into the nozzle of the gas fireplace, throwing the valve wide open.

The demon thrashed, trying to look behind her swollen body as she blimped up even faster than from the helium.  In a moment she was a fat, full, floaty sphere of a demon, her head, hands, feet, and tail stuffed in a big shiny purple ball.  I held her tail like the string on a balloon.  There didn't even seem to be any fight left in her, her eyes were closed blissfully, her palms pressed against her bloated sides, biting on her lower lip.

I looked around the living room, there were a number of unconscious partiers, and everyone with their wits had fled.  The field was ours.

I helped Bubbles up, she was a little rocky from her sudden expansion, "You ok?"

"Yeah," she panted, "I just need to catch my breath, wow!"  She was breathing rapidly and her face flushed.  When I looked at her chest, I blushed and giggled.

"I know,” she nodded, "We're all nipping out, even Expandra."  It was true, even the blimped magicienne was showing her excitement through the blouse drawn tight over her greatly inflated breasts.

"Airtankgirl," Expandra squeaked at me, "Get upstairs, find my sister.  I'm too fat to fit in the hall."

I handed the Demon's tail to Bubbles, "On it, and see if you can manage to get something to get Expandra down as well, we can't leave her floating on the ceiling."  I tired to vault the banister leading to the second floor, but I found that the Demon had pumped me up so round that, while I didn't lack strength, I certainly didn't have the agility to lightly vault a banister in my bloated condition.
    I settled for awkwardly climbing the stairs, my thighs bumping into my lower belly with each step up.  I waddled down the hall, finding the open door with the three fat-bellied girls, bursting out of their costumes, lying semi-conscious on the floor.  I could see from the taunt material over their inflated breasts that they were just as excited as the rest of us.

"Tabitha?"

A good-looking blonde in a tight, scanty witch’s costume, made tighter and scantier by her big, round, soft belly and her ballooned breasts, rolled over a little and looked up at me.  

I took her arm and hauled her upright.  At least she wasn't heavy.  Holding the shaken, swollen girl upright, we two young women, our distended figures bulging roundly against each other, waddled and staggered downstairs.  I hated to leave the other two bloated girls, they were in no danger of getting any fatter at least, but I knew they were going to have some rough explanations when everyone came to.

Downstairs, Bubbles had the Demon bobbing above her by the tail, and Expandra was holding onto one end of her burst cummerbund, while Lynn anchored the other.  We made a slow, waddling retreat of our bulgy forms our of the sorority house and into the night.

The need for privacy and space to sort ourselves out led us to a darkened field in the park behind the Delta house.

Expandra's sister was coming around, though she was more surprised at the shape of her sister.  Expandra hushed her before she could divulge her name,"-Wow...I mean you were always my big sister, but who knew you'd get this big...I can't believe how bloated you got, you're like a blimp!"

Expandra hugged her round sister, anchoring her buoyant body to the ground, smiling, "That's what big sisters are for, but you aren't exactly slender anymore either, you might have to get used to being fat for a while until I can sort our figures out,” She hugged her sister's swollen belly against the inflated expanse of her own body, "I might be able to find someone to vent all the gas in us to."

"Don't let me find you doing it,” I warned her, "If I catch you blimping up some poor girl just so you can get skinny faster, I'll beat the stuffing out of you."  From the set of Expandra's lovely jaw, I could tell we were still enemies.  I was sure she wouldn't inflate Bubbles or me right now.  Either of us would blow up but I'd still be strong enough to clobber her.

"I think we have a more pressing problem than our figures, ladies,” Bubbles tugged on the Demon's tail, causing her to bob in the air, "What do we do about her?"

"Hmm it seems only fair, she made me this big, she should get the rest of this gas back,” Expandra growled.

"I dunno,” Bubbles said, pulling the inflated demon down where she could gauge the pressure inside her by squeezing her round body, "I think she's pretty full, I don't think she could hold much more without bursting."

"Yes, quite,” Expandra smiled evilly.

"Hang on there," I said, "I'm not so sure we can just explode a creature who's only crime I can see, is making us a little fatter and giving us an orgasm."

Expandra whirled on me, well actually she waddled, "Do I look a little fatter?"  She raged in her cartoonishly high-pitched voice, "I'm so blimped up, I float! I look like a parade balloon!  My sister, look at her, she can't go back to a sorority looking like she swallowed a beachball."

Tabitha petted the soft, bloated bulge of her belly, "Actually its rather nice-"

"Hush!" the massive magicienne snapped squeakily.

The Demon's eyes snapped open and she smiled at us,  "Mmmm how lovely, I feel so huge and you are all fattened up nice and plump, though, it looks as if a couple of you could use some more of this wonderful gas you filled me up with.  How about it?"

"That's it, she's toast," Expandra squeaked.

"What?" The round purple demon asked in her own helium voice, "You all like being big and fat, I can tell," she grinned, "I just wanted to play and share too."

"I feel like such a dunce,” I said, "She isn't evil, almost the opposite, she just wanted to be friends and she thought that inflating us all was the way to do it.  And we beat her up for it."

"Don't take it too hard ATG,” Bubbles said, "it really doesn't look as if she's all that beaten, she's just blimped."

"Share this,” Expandra said, pushing her hands out at the distended demon.  Expandra's bloated body deflated, her clothes loosening on her as her figure regained her normal shapeliness.  The helium filling her was forced into the tight round body of the demon that gasped delightedly, creaked tightly as she ballooned up again, and then...KABOOOM!  She burst into a cloud of purple dust.

The concussion knocked all of us down.  Expandra, the most agile, landed on her trim fit bottom, regained her feet, and pulled the air from her sister, puffing herself back up to a round fullness.  She waved the now-slim Tabitha behind her, while she faced me down as I stood up.

"How could you?"

She pointed a finger at herself, "Villain,” she said, her voice back to normal, as if explaining everything, "Not tonight Airtankgirl, but soon."  She warned me, backing away from us.

I was too tired, and too bloated for a fight, so I nodded, letting the sisters fade into the gloom.  I sighed tiredly as Bubbles waddled up next to me.

"Well here we are, no party, no dates, fat and bloated again, and I'm never going to get my deposit back on this costume.  I think they have a strict 'your burst it, you bought it' policy

Something purple and voluptuous grabbed us each by a shoulder and hugged us. We leapt back as the once again shapely demon smiled at us.

"Oh she's great, I can't wait to find her again!"

"You exploded!"  I said.

"Of course I did, I was full.  Mmmm, and I was so full too!" She purred in her deep demonic voice.

"You explode often then?"  Bubbles asked.

"As frequently as possible, don't you?" she asked, her waist bulging, and Bubbles and I felt a pleasurable pressure within us.

"No, " I gasped firmly, "Not at all, ever."

"Oh,” The Demon said, mollified, her waist slightly fuller as the pressure in us mortals faded, "Good to know.  I'd like little hints like that if I'm going to stick around here."

"You're staying?"  I asked, aghast.

She nodded, her big purple horns bobbing, "Sure, you guys couldn't exorcise me away.  We're going to have so much fun!"

"Aw, hell,” Bubbles was grinning at me, "What?"  I asked.

"Can we keep her?"
