Warnings: huge inflatable superheroine protecting city, fighting, wrestling and deflating.

Don't like, don't read. Story is inspired by works of @AECV

A towering raven haired giantess easily picked up a police car, ignoring bullets that simply bounced from her stretchy impenetrable skin. Cops barely managed to jump out, before she lifted the car to the height of a ten-storey building and threw it in the direction of a police chopper.

 Diana was an inflatable supervillainess, doesn't really sound dangerous does it? Think again. With strength matching her size of a small skyscraper and having virtually impenetrable skin she was too tough for police and even the military to deal with. Besides that, she was smoking hot. Pretty face with meter long eyelashes, beautiful straight nose, luscious lips, long legs and of course zeppelin sized breasts of ideal spherical shape clad in a red super stretchable bikini top. Truly a lethal beauty.

 - "Oh no! We can't stop her, run!" - cried some voice near the reporter.

 The camera started to shake and the TV broadcast was soon interrupted. Video switched to a news commenter, who explained that the situation was dire, but police will soon have it under control. Of course that was a lie, but what else could he say?

- "Looks like no rest for us this weekend. City needs to be saved again." - said Alan turning off the TV. He looked at his girlfriend Alex, who was sharing a blanket with him. They were more than just a couple of friends with benefits, he often assisted her in her adventures.

- "It is too easy to bully little ones. This gal needs to face someone of her caliber.” - said Alex. A part time superheroine, part time student. She's a somewhat slim tomboyish girl with cropped blonde hair and beautiful purple eyes. Bold, outgoing and a natural leader yet she could be soft when spending time with Alan.

 Alex quickly changed into her green and black battle bikini made of a special type of latex material that managed to withstand enormous tension and bullet impacts. Meanwhile Alan went into the yard near their house and rolled out the air compressor.

 "Are you ready, honey?" - he asked, wielding a long air hose. Alan is a dark haired curly boy, wearing his vest with many pockets. While his role in the duo is secondary, his help was absolutely necessary in many engagements. After all it is his duty to inflate his mate into her powerful combat form of a battle giantess as well as helping her return back to her normal day to day shape.

 "I'm always ready for you, you know." - said Alex, taking off her boots and pants. She stood there in front of him, slightly shorter than Alan, a skinny nerdy tomboyish girl, wearing just her bikini and a small plastic cylinder in her navel. This feature can be easily mistaken for just a piercing, yet it was both the source of her strength and her greatest vulnerability.

 Not wasting any more time Alan yanked the plug from his girlfriend's navel. Yes, Alex is filled with air and now this air started to quickly leak with a funny hissing sound. Alex shrank a little, her girly muscles quickly vanished and her arms hung limp as weakness grew in her inflatable body.

 "Come on, Alan, no need to always tease me like that, please" - reasoned Alex barely standing on her softening legs.

 "Sorry about that, I just like that part too much." - with these words, Alan inserted the nozzle of the air hose into her navel. "Brrrr, Fwoosh" - went the compressor as it immediately started sending more pressurized air into the blonde.

 Alan put away the small plug into one of the many pockets of his vest. Still his eyes were on Alex. The tiny blonde did not just regain what she had lost, but she grew bigger and taller. In less than half a minute she was twice as tall as him and that was only the beginning. She mostly grew keeping her proportions, but there were exceptions. Her muscles became more prominent, her butt rounded and her bust went from almost flat to voluptuous. A normal sized girl with this kind of figure would count as well-endowed. But as a full grown giantess Alex sports two balls almost five meters in diameter.

 "I think I'm done, honey, turn it off!" - said Alex from a height of roughly fifty meters. She tried to inflate even bigger before, but at the cost of losing agility and flexibility - not a good trade-off for fighting. Also the air hose was not long enough for going any higher.

 Alan shut the air compressor off and waited in front of his girlfriend's feet. She gently pinched him between her thumb and index finger and lifted him to her navel. There he yanked the hose out and installed the plug. Not the tiny one he pulled out several minutes ago, this one was a battle giantess tactical plug. Big and sturdy enough to keep all the pressurized air inside her.

 "Thanks honey! Time to kick some ass. You just sit here and stay out of harm's way." - Alex lifted him up to her cleavage and carefully pushed him between her soft pneumatic boobs. This was not just the sexiest, but also the safest place in case of combat, She knew that her friend would be cushioned, not smashed by any blow and wouldn’t accidentally fall down from her skyscraper height.

***

Diana scared off the city police and dealt with armored APCs of the national guard. She actually didn't need to destroy all of them, just cause enough havoc to distract attention from her little partner who was robbing the magic vault, while everyone was busy with the giantess. She was pretty bored with her mission when Alex appeared, bouncing towards the crime scene.

"Ah, at last a worthy opponent!" - Diana exclaimed, estimating her chances. The blonde was slightly taller indeed, yet was she good at fighting and wrestling especially against battle-hardened enemies such as Diana?

"Give up and deflate immediately in the name of the law." - Demanded Alex, quite over-confidently.

"We shall soon see who will deflate." - spat Diana, dealing a punch into Alex's belly. Diana was surprisingly fast despite her inflated physique. Although she aimed for the vulnerable spot, her punch just knocked Alex down to the ground, rolling and bouncing on the parked cars and into a nearby house. No real damage, though.

Diana didn't waste her momentum, she ran towards her rival while she was on the ground, but Alex recovered quickly and met Diana with an upper-cut, not very precise but yet good enough to send the villainess flying.

After the initial fistfight both became more cautious and approached each other making circles, trying to flank the opponent and covering their navels while seeking an opportunity to strike.

Diana made a short blow in the direction of Alex's face, now that it looked like a good time to get her, while she was off-guard. And of course Alex lunged forward. Little she knew, that was a faint move - just a trap set by a much more experienced fighter. With her left hand Diana caught Alex by the wrist and twisted it. When Alex instinctively tried to use her other hand to free herself from Diana's grip, she exposed her navel. Diana needed only a split second for her rapid move. She reached for the plug sunken into Alex's belly, pinched and pulled. A loud hissing sound was a sign of her success!

Alex managed to hit Diana in the jaw. Although besides the hollow boom sound of a balloon hitting another balloon there was little effect. Diana was stunned for only a second or two. However Alex used this precious little time to check her navel. That was yet another mistake. Her plug was already gone, she couldn't stop air leaking out of her. Maybe she could counter attack instead and uncork her dark haired enemy? Perhaps. Instead she just felt the jet of pressurized air hissing out of her.

 This was the first time in Alex’s short career in which she was actually deflating in battle. Of course this made her panic. Her huge inflated boobs closed her view, so she couldn't see her own navel. But she felt the tingling and relaxing loss of pressure and heard the all too familiar sound of the air hissing out of her valve.

 Alan didn't see much, his field of view was limited to a thin cleft between two beautiful balloons as he sat deep down in Alex's cleavage. Yet he also heard the sound and felt the walls around him softening with every passing moment.

 It takes a long time to deflate a giantess completely. At least half an hour to go from a powerful superheroine to a flat heap of crumpled rubber on the ground. Yet pressure and strength drop quickly in the first minute after pulling the plug. While panicking Alex had wasted some precious seconds and when she regained her resolve, Diana was also ready to wrestle - she basically grabbed Alex by her wrists. Alex tried to free her arms, but they went traitorously soft and weak in the iron grip of Diana. A little bit of air was displaced from the hands of the blonde giantess and critically weakened her. Alex was still taller than Diana, yet she was already overpowered.

 When Alex had her fists blocked, she tried to kick Diana in the knee. Again with no success, Alex's feet just softened and caved on impact against the taut rubbery skin of Diana. The fact that the blonde giantess lost air from her limbs first certainly didn't help her fighting abilities. Her chest, head, her glorious boobs and butt remained at full shape, maybe just a little softened, but her fists, her arms, legs and feet - became weak, caved on every impact and made Alex basically harmless for her rival.

 "No, I can't lose!" - roared Alex, desperately jerking in Diana's grip, trying to free her hands.

 "But you've lost already, my dear. Relax, admit your defeat and deflate, that's what you can do now. But of course you may continue your amusing attempts to fight me - this way you just lose your air faster." - cooed Diana. Of course she was teasing and mocking Alex. But she was also absolutely right. Alex had lost.

 Her air monotonously hissed out, her dropping pressure being replaced only with growing despair. Alan felt it too, although he couldn't see much from his hiding place, he heard everything and had the general idea of the situation. He really wanted to save Alex somehow, but what could he do? If his gigantic girlfriend failed, how could he defeat Diana? The raven haired giantess would probably crush him like a bug...

 Meanwhile Alex's arms grew weak and limp enough for Diana to press them against Alex's sides. Then Diana pulled her deflating rival closer, embracing her into an evil kind of embrace. Not because she loved her, but to squeeze the air out of Alex faster.

 Alan poked his head out of his girlfriend's bra to see what he could do in this dire situation. But he was smothered by yet another pair of giant boobs, as Diana's chest pressed into Alex's. He even considered jumping into Diana's cleavage to somehow climb down to her navel later, but this was too risky and the window of opportunity soon closed, because Alex started to slide down as her legs, thighs and spine softened - she already couldn't stand upright without support.

 Alan descended together with Alex sliding over Diana's red latex bra and had a great view of her fantastic underboob, then her tummy. Alex's legs softened but could at least slow her falling. Diana held her in embrace and thus there was a lot of rubbery friction between the girls. So Alex didn't just quickly flop on her knees in front of Diana, but went down in a very slow motion, almost gracefully. Then Alan saw his opportunity. As long as Diana wasn't aware of his existence and didn't realize the threat, Alan had a one time chance to make a crazy jump. If he failed - he'd fall from a huge height.

 Alex continued sliding down, her green combat bikini top was rubbing against Diana's belly. Then Alan saw his target - a big cylinder of the same shade of fiery red as Diana's bikini. It was in her navel of course. When the distance was about one meter, he pulled himself from between Alex's softening boobs and jumped. He tried to not look down and slid on his butt over Alex’s green latex bra material towards his objective. And he barely caught it, grabbed the plug with both his hands, pressed his feet against Diana's taut belly and pulled as hard as he could. At first it barely budged, but then his efforts were rewarded. The plug started to slide out and with a loud "Pop" sound it came out of Diana's navel. A jet of pressurized air then threw Alan away.

 He hadn’t thought through what he'd do after pulling that plug. He just had no time for planning. Of course Alan could just fall to the ground from this terrific height but he was lucky, as he landed on the soft cushion of Alex's shoulder. It caved under his weight on impact slowing him safely. If Alex were still fully inflated, Alan would probably bounce off from her skin and still fall to the ground. So sheer luck and his soft girlfriend saved him.

 Diana reveled in her glory and was oblivious at first. Of course she heard hissing, but assumed it was still her deflating rival. It was louder but so what, that could be due to the squeezing she was giving Alex. Last but not least - Diana's magnificent boobs closed her sight directly in front and below from her. So Alan managed to quickly escape before he was even noticed and got into the relative safety of Alex's cleavage. He dived there head first, holding Diana's plug in his hands. Alex significantly deflated and her chest wasn't as full and taut as it used to be, so squeezing down between her boobs wasn't a problem. On the other hand, these sagging orbs didn't cover him fully so he crawled under the bra and hid the plug under the green latex.

 Unlike blissfully oblivious Diana, Alex saw everything. She wanted to cry in joy, yet suppressed her feelings and waited till Alan hid safely under her bra. "You are my hero, Alan" - she said in a quiet voice.

 "What are you mumbling down there?" - asked Diana.

 "Well, nothing. Just thought about my boyfriend."

 The blonde was on her knees and in Diana’s blind spot. Instead of lifting Alex up to her face, Diana kicked the poor deflating girl, so Alex flew back a few meters and landed on the parking lot. There Diana could see her face without bending. Obviously Alex was already sagging here and there, her arms were limp and bending unnaturally, her legs just folded under the weight of her body. She still had a pretty awesome inflated bust and ass and her tummy didn't lose all the volume, but of course, these remaining parts were of no use for Alex. She must be suffering her utter defeat, but something was wrong.

 "Why the hell are you smiling?" - asked Diana.

 "Just smiling at my happy thoughts. Can I just enjoy a little dreaming, while I'm deflating helplessly? You won, are you not happy yet? Should I weep because I'm such a loser?"

 "But just a minute ago you fought against it and now you’re just accepting your defeat?"

 Diana listened. Hissing was still very loud and came from a nearby source. Not from that stupid blonde. She immediately checked her navel with her hands and there she felt a stream of air tickling her fingers. Immediately she realized there is a growing weakness in her toes and fingers. Of course she tried to close her navel with her finger, but it was useless - she needed the plug.

 "You bitch! When did you do it? I held your hands all the time." - cried Diana.

 She looked around, bent and started searching under her feet. Her airplug was red and should be visible on the ground...

 "What's wrong, cutie? You look worried. Did you lose something?" - now it was time for Alex to have some fun at Diana's expense.

 "Give it back! Now!" - yelled Diana. She did her best to look and sound intimidating yet her voice betrayed her.

 "Give back? What?" - cooed Alex.

 "My plug! Where is it?" - Diana ran towards Alex. Suddenly she was not as fast as she used to be, her legs didn't bounce and they deformed under her weight. She put her knee on Alex's belly and grabbed her left hand, forced her to open her fists - first left, then right. Of course she found nothing.

"Maybe you are sitting on it?"

Then Diana stood up again, which was clearly difficult to do, grabbed Alex by her sides and tried to lift the crumpled blonde giantess in the air. Diana's arms folded and failed to bear the weight of Alex.

"Damn. I'm sure it is under your ass" - howled Diana. She then tried to kick, push and roll Alex. Moving a half deflated girl turned out to be hard as well, although Alex couldn't resist actively, she just caved and crumpled wherever Diana applied some force to her. Diana's hands were softening too and that didn't help either.

 "Oh come on, stop tickling me!" - laughed Alex.

 Finally Alex was rolled face down. And there was no plug on the ground, where she had been before!

 "Then you must be hiding it in your bra!" - guessed Diana. If she had this idea earlier, she could easily get her plug back from a half deflated superheroine and her miniature boyfriend. But after losing so much time and air, her chances were slim.

 Of course Alex and Alan heard it. The safe hideout between two boobs and a green latex bra was no longer safe.

 "Run, Alan! Save yourself, honey!" - murmured Alex.

 Not wasting any time, Alan grabbed the plug and jumped out of Alex's cleavage. She lied face down, so her bra was on the ground - which made his escape much easier. There was yet another small problem, he had to virtually crawl towards the open sky beneath the rubbery skin of his girlfriend covering all the ground around him. Well, actually it could even be a pleasant adventure, if he wasn't in a hurry.

 Diana spent some more time trying to roll Alex over once again - this time to search her bra. The brunette struggled and muttered obscenities, because doing it for a second time was even harder. Then she saw a tiny boy running away at full speed skirting the cars in the parking lot. Most importantly, he carried something red in his hands.

 "Hey, stop right there or I'll crush you like a bug!" - She threatened while starting to run after Alan. Of course she merely waddled and couldn't run really fast. But the sheer size of her legs gave her a speed advantage. Alan was doomed!

 On her intercept course Diana had to step over Alex. Poor blonde giantess already started to collapse, her legs were mostly flat overall. But she still had some air inside and more importantly her fighting spirit. Alex just moved her elbow in the way of Diana's foot, in her mostly deflated state this required serious effort, yet it paid off well. Diana tripped and slowly fell on the ground wailing like a banshee. She tried to grab Alan, as she fell forward, yet he barely escaped. On impact she lost even more air especially from her arms and knees, trying to stop her fall. Maybe she could strategically fall on her chest instead, pushing some air from it to her limbs?

 Anyway, Alan managed to run away and only stopped a relatively safe distance from the villainess. She cried obscenities and threats, but her voice grew quieter, notes of arrogance and anger being replaced with desperation, as he ran further. Running with a big plug in his hands drained Alan's stamina so he needed a breather and of course he was curious. So he stopped to look back.

 Diana still struggled to stand up after she tripped. Her legs traitorously folded at ankles and knees. Then the deflating giantess tried to crawl towards Alan...

 "Okay. I'm sorry for being rude. Just come and give it back to me. Please." - said Diana. - "I won't harm you, I promise."

 "Of course you won't. Now you just can't."

 "Come on, do you want me to beg? I... I will do whatever you want." -  Diana's voice suddenly became sultry and seductive.

 "Whatever I want? Let me think. I want you to become a huge helpless heap of crumpled rubber."

 "Why are you so cruel? I don't want to deflate, please plug me."

 "This makes it even better. I like deflating girls. But when I do it to my friends or my girlfriend, they don't mind, they like it too. This is cute and lovely, but lacks the thrill of deflating an unwilling girl, such as you. Because you deserved it." - Alan smiled.

 "You are a freaking pervert! But you know what? I won't say anything from now on. No more entertainment for you!"

 Diana was true to her word and didn't emit any more sounds except for hissing of the air blowing out of her navel. Her body slowly collapsed to the ground, covering the cars in the parking lot. Though even flat and crumpled she still looked very appealing.

 But Alan didn't pay much attention to Diana's game over. He went back to Alex and they had some sweet talk.

 "We won, honey, the city is saved." - said Alan, when he reached his girlfriend's face. Alex still had some air left in her head and chest. The rest of her body was practically flat, though.

 "That's all because of you, Alan. You acted so brave."

 "We did it together. Alone I wouldn't have a chance against her."

 "So we are not just a beautiful couple, we also make a good team! By the way, I heard what you said to her. Is it true? Do you like deflating girls against their will, is it true?"

 "Well, honey, I know it sounds a bit creepy..."

 "No, no, nothing wrong with it. If you want it, next time you pull my plug, I'll play along and pretend that I don't want to deflate. Maybe even try to fight and wrestle a bit."

 "That would be a neat thing to try, honey."

 Alex fell asleep and didn't answer.
