“Ugh, Anon, why did we have to take the bus? It's a beautiful day outside! We could have flown. I even restocked my helium."

“I've told you before- We don't have clothes that fit you when you're that big, Bloona," Anon responded, as Bloona scoffed with a smile, rolling her glowing blue eyes.

Anon was your standard, thin and tall human at the end of his young adult years, but Bloona was not a human at all, but a peculiar creature of blue skin that shimmered like polished rubber, and her eyes had light blue sclera and glowing white irises, and instead of a humanlike face with a nose, she had a short, chubby muzzle that matched the chubbiness of the rest of her. Beyond that, she had fins on her forearms and adorning the top of her head like giant ears, and a short, fat, almost barrel-shaped tail extended from her pants, her tail ending in an open jet nozzle, complete with aerobatic elevators and a rudder just above it, like a plane's tri-pronged tail. The tip of her tail did not house the only engine in her body, her lower legs as well as her forearms appeared to each have a pair of fan arrays, currently closed like the shutters on a window. 

“It's not like I'd be flashing anybody. I can just dissolve all my private bits into my skin." Bloona rolled those glowing eyes of hers as she spoke, tugging at a corner of her sleeveless blouse as a hand scratched her collarbone, the sound of her peculiar rubberlike skin scraping against itself squeaking slightly. He could see the space between her collarbone and her trapezius musculature of her neck, those little dips were hollow and evidently led all the way through her synthetic body, the intakes for her tail jet as well as her forearm fans. Under her skirt she had intakes for her leg-fans on the sides of her thighs.

“Your tits get huge when you inflate yourself, you know that?" Anon uttered judgmentally. “Nipples or not."

“Now you're gonna act like you're above that, huh? You know you like 'em big." Bloona grinned smugly as she crossed her arms beneath her bust, as if pushing her breasts up subtly. Anon could see her nipples form beneath the blouse, suddenly getting sharper and more pronounced on Bloona's command. With a muffled, hollow hiss of air within her body, Anon watched her breasts begin to puff up, Bloona gaining a cup size in half a second.

“Stop it, we're in public," Anon grumbled, unable to fully conceal his blushing. Bloona simply 'tsk'ed with a cheeky grin.

“Alemont station, next stop," The PA system of the bus broke their hushed conversation and the bus began to slow to a stop. Anon stood quickly as if to break the reparté with his companion, Bloona standing to follow him out. “Thank you for traveling with us," The bus driver, a simple automaton positioned in the driver area turned around with its cold and robotic head, two eye-cameras and an unmoving horizontal crack positioned where a mouth would be. 

“Thanks buddy! Keep up the good work!" Bloona spun in place as she deposited a couple credit coins in the driver bot's tip jar, her knee-length skirt twisting from the sudden centrifugal force before she followed quickly after Anon, who paced ahead with his hands dug firmly into his sweatshirt pockets. She giggled, gunning her tail engine and leg boosters to glide over to him with a whoosh, hands stuck to the sides to balance as her propulsion carried her up to him, hitting the ground in a little stride. Though her leg intakes were covered by her dress, she seemed to be able to feed air from her neck-intakes into all five of her body's jets if she needed to- plus her engine itself had intakes on the sides that could open up. “So you don't want to fly with me because you don't want people to see me with you?" Bloona scoffed as they exited onto the sidewalk, walking across the parking lot. “You're the one who bought an Anthropomorphic Zeppelin Companion android to be your girlfriend, Anon."

“Yeah, and they sent me you." Anon smirked, going on with his explanation. “Look, it's that they'd see me with you, naked. I'm just not comfortable with that."

“So what, I gotta buy a jumpsuit, or some super stretchy clothes, or a friggin bedsheet to make into a toga or something to cover my already concealed lady-bits when I inflate, and then you'll take a ride on Bloona Express?"

“I'll think about it."

“Alright! Got my foot in the door!" Bloona pumped her fist a little as she skipped along after her owner. For a human her size, she would have seemed especially light on her feet, a good 5'11" and a somewhat chunky build yet each step she took in excited little hops was higher and longer than one would expect. Of course, she gunned her proud engines with subtle whirrs and wooshes as she happily trotted along, giving herself little boosts as she went.

“I'll go get a cart," Anon said as they entered the supermarket. Bloona began to walk on ahead, happily humming to herself, until another robot slid out in front of her, with a bright bold number 27 emblazoned in the corner of its chassis.

“Attention, attention," The little legless kiosk-looking thing blared, blocking her path. It was a simple checker-striped security bot with a police cap stuck atop its pointed, obelisk zenith, the screen on the security bot displaying what looked like a clip-art gif of a cartoon policeman blowing a whistle with his hand up. “Baloona Nymos. Robotic Citizen Registry Number: AC923771. You are barred from this property for the following offenses: Destruction of Property. Disorderly Conduct. Indecent Exposure."

“Indecent exposure?!" Bloona huffed, incredulous as she stuck her hands on her big hips, engine-tail wagging once behind her. “I concealed my privates in my skin!"

“Honestly, miss Nymos," another security guard stepped forth from around the corner, a large human man with dark skin, one of his arms replaced by a sophisticated prosthetic. Judging from the scars across his body and face, it was clear that this security guard was probably in the armed forces during his previous career, and more than likely lost his old arm in a battle. “You have really big boobs when you puff up."

“See?" Anon stepped forth. “Ricky knows what's up. They're like beach balls."

“I mean, personally, I wasn't complaining, but BuyMart is a family establishment." Ricky chuckled in his deep baritone.

“Alright. Can I come in?"

“As long as you don't pretend you're Godzina and my store is Edokyo again."

“Look, I was defending myself, alright? I was in fear of my life."

“Bloona, it was a cardboard cutout of The Sauce Guy. An advertising display."

“He's scary! I got freaked out! Why is he holding the knife like that?!" Bloona reasoned, as Ricky chuckled and shook his head, and Anon sighed into the palm of his hand.

“I'm sorry, she's got a serious phobia. She won't do it again," Anon put forth.

“The balloon girl with a fear of sharp objects," Ricky chortled, clicking his tongue. “I mean, shit, I'm a vet and I drive a Fort Challenger that I paid too much for."

“I am a robot and I enjoy a full charge," The security kiosk bot, so named Twenty-Seven chimed in, the display shifting to show clip art of a cartoon thunder bolt and a smiley face. “We all appear to have stereotypical qualities about us. Ha."

“That's great, 27," Anon dryly noted back to the security bot, whose serial number ended in 27 and therefore went by that monicker. “Bloona, babe, you're sorry right? Say you're sorry."

“I'm sorry for defending mys- Ow!" Anon elbowed Bloona in her side sharply, cutting her off. “Alright! I'm sorry!"

“Alright, guys. Head on in. But I'll have Twenty-Seven keep an eye on you," Ricky patted his automaton partner, and immediately out came the security bot's stun baton, sparking before Anon and Bloona violently.

"Statute 2-47-B9-C states I must inform you of the use of kinetic force before application," The bot rang out as Bloona jumped. "If necessary to ensure the peace, you will be electrocuted in an EM Pulse Frequency effective on Android Individuals until incapacitation is achieved."

"Eeek!" Bloona quickly ducked behind Anon, her eyes trembling at the crackling electricity. "Alright! I'll be good!"

"Acknowledged. Please enjoy a safe shopping trip at BuyMart." The stungun retreated just as quickly as it was deployed. 

“Sheesh, if I was a box on wheels I'd be an asshole too," Bloona whispered to Anon as they passed into the store, Twenty-Seven following behind, just far enough to keep an eye on them.

“I heard that."

“Why don't you go hear some bitches!" Bloona waved her arms at Twenty-Seven.

“Nice internet humor. You really “owned" me… Ha. Ha. Statement was deceptive. You should… Touch grass."

“Damn, they must've upgraded 27's sass drive," Anon chuckled as Bloona blushed and shook her head.

“Whatever. I'm going to the deli. I could use a good nanite smoothie while we shop," Bloona informed. “I could go for… Mm, I'm thinking blueberry flavored."

“What, it's not good enough for you in a can?" Anon rose an eyebrow.

“At room temperature?! Heck no! Everything's better on tap. Meet you in the robot aisle?" Bloona began to walk backwards, pointing at Anon with a snap of her blue fingers and a little boost of her inbuilt jets, her skirt fluttering as her tail bobbed.

“Right. I'm gonna be in the freezer section first and get my tendies."

The two of them separated, and Bloona made her way over to the little resturantette section of the store where people could buy ready-to-eat food, complete with a small seating area, getting in line. She could smell the fried chicken, thick-cut potatoes, fresh macaroni and cheese and other goodies, though it wasn't exactly appetizing to her nose. What she was after was nanite paste. Androids like her didn't eat the same food as humans, since they can get most of their energy from literally charging themselves every other night. Android food can let an android regain energy, However, maintaining an android's body is similar to how a biological creature would heal itself- with food, rest and time.

“Hi! One blueberry nanite smoothie please!" Bloona cheerfully ordered at the counter once the queue went down, ready to pay. The attendant looked her up and down once.

“You want some Aralatex mixed into that, too?"

“Oh, yeah. That sounds great!" She paid, and the attendant went to work making the android-intended beverage before giving the slushie to her, smelling deeply of rusty iron, used motor oil, and sweet blueberry syrup. She appreciatively took a heavy gulp, brainfreeze hitting her and her pose going rigid for a second. As if her system was glitching, one of her arms suddenly extended and grew in size and bulk, before one of her legs followed suit, kicking out in front of her as it gained length, her internal endoskeleton lengthening and contracting for a moment here and there.

“Oof, brainfreeze," Bloona embarrassedly chuckled, shivering. The guy behind the counter didn't seem too impressed, going on with his job and she walked away, enjoying her beverage slower this time.

Android food was designed to work with the synthendocrine system of androids like hers to help maintain her body, like her smooth, tough Aralatex skin. Ballistic latex, or Aralatex is a common skin material for androids, though in this case the proprietary skin of Anthropomorphic Zeppelin Companion androids was somewhat different, in that it is intended to stretch and retain its form and tension with ease, as well as function as a muscle, giving redundant control to their bodies on top of their internal synthetic musculature. Not only did AZCs change their body shape by filling themselves with air, but their internal endoskeleton was designed to extend and contract, giving them the ability to change their size outright. 

Though Bloona had spent some time in the deli area, upon walking over to the Synthetics aisle, noted that Anon was not back yet. Guess I'll just wait for Anon here and pick out my stuff, she thought to herself with a hearty sip of her refreshing drink. She grabbed a big jug of distilled water and some of her favorite nanite and cyberprotein blends, the Sonny's Choice brand. The bags had a picture of a simpler robot on it, the type with cloudy-clear plastic skin and humanlike faces. Good ol' Sonny, she smiled to herself.

“Damn, Jane, I can't reach it," Bloona heard from down the aisle and turned. There was another pair, an android and a tan-skinned human with long braided pigtails that drooped over the front of her shoulders- and the android seemed to be one of Bloona's own kind, an AZC model with bright, cherry red skin and brighter LED optic-eyes with orange sclera. He seemed to be a male, with a toned, flat chest (though his hips did seem a bit wide for a male), with almost dragon-like features. He had double-curved horns and a ridge of scale-like, hard rubber spines extending down his back and his long tail ending not in a plane tail like Bloona's or a traditional zeppelin rudder, but a pointed spade shape, and instead of hard-soled plantigrade feet, he had wide, bare digitigrade paws. On top of this, he had wings on his back, poking out of a shirt that looked many sizes too small for him in the form he was in. In fact, it looked like he was right about to burst out of his clothes as it was, and he was hardly pumping himself up for his height. Surely if he just increased his internal pressure to a measly fifteen PSI he might rip his clothing right off of himself.

“It's okay babe, we can find an employee to get a ladder," His partner Jane remarked, her watching him hop there. “Don't… Careful with your wings, Zeppo!" She said as he beat them slightly to try and gain altitude. He was trying to get a nitrogen canister from the top-stock area atop the high shelves, it seemed- Bloona smirked to herself. Those canisters were heavy and he'd probably just knock it onto himself. She should really do something about it-

Wait, she thought. Is that as tall as he can get? A snicker rose in her mouth, and she watched as the little AZC shrunk in defeat, hearing Zeppo sigh dejectedly and go from a good Eight and a half feet tall- his presumed maximum height- back down to six foot, still taller than his significant other by almost half a head. He did not change the volume of air within himself, it looked like, as he grew both chubby and muscular as he shortened. There was no way that six foot was his nominal, fully collapsed form, Bloona figured. She knew that her own form, a large-size AZC, can variate between her current, nominal 5' 9" all the way to over twelve feet tall. She even knew that medium sized ones could get bigger than a measly eight-plus feet, like he had. He must have been a size small. That's weird… Never ran into a small before, she mused with another sip. Most people who went for an AZC typically had a hankering for size, after all… Like her own owner she could dwarf in an instant whenever she chose.

Stepping forth and placing her stuff down, with only her smoothie in her hands, she began to grow. She let her endoskeleton extend and her internal ballasts fill her with a deep hiss. She felt the cup shrink in her hand, the aisle seeming to get narrower and narrower as seconds passed. Her Aralatex skin soon pressed against the inside of her once comfortably loose clothing, her knee-length skirt retreating up her thigh. Despite her growing desire to grow, she knew not to overdo it, feeling her blouse strain against her expanding bosom, the fabric creaking as if fibers were to begin snapping at any moment.

“Going for nitrogen, huh?" She let out, her voice deeper now that her lungs were stretched larger within her own body, plenty more room for them inside her expanded ribcage. Soon she looked down on the two of them plainly, the strangers looking up to her not exactly expecting a helping hand, as she hefted a nitrogen canister to plop down into their cart in one hand, her strength aided by the air pressure within acting against the tension of her skin. “I usually go for sulfur hexafluoride if I want to stay terrestrial. Density's nice- plus, the boyfriend loves the deeper sound when we're playin' around. That good 'bwoomp', y'know?" She crossed her legs and leaned against the top of the shelves as if a bar counter, looking down upon her fellow android and his human. “Dunno if you'd know anything about that," She pointed down to the other android, tempted to pat him on his head like a child. “Don't think you'd have the volume to really get the same effect!" She laughed. “Man, you're so small! How big can you get? Eight-foot-three?"

“Zeppo-" The human tried to interject, putting her hand on her companion's shoulder- but as the indignant look on his face grew, he stepped forth and began to grow once more.

“Eight-foot-six!" Zeppo indignantly answered, his dragon-like rubber android body growing to that height- but in swelling up his chest, his shirt ripped a little, though it stayed on him and strained as he grew, flexing the growing musculature of his aralatex skin.

“Is that it?" Bloona smirked down at him. Like being challenged, she grew as well, opting for her more rounded look rather than cut and muscular. “Your owner couldn't handle a real blimp like me so she bought you?!" Bloona laughed.

“Jane isn't my owner!" With this indignant assertion, Zeppo's shirt ripped off of him. It seemed that while he was out of room to grow lengthwise, he still had girth to put on, puffing up his muscles evermore as he continued to inflate.

“Aw, jeez," Anon suddenly approached behind Jane, who was currently gawking up at the quite literal chest-puffing match taking up the entirety of the aisle before them- that a good amount of other shoppers had now stopped to witness. “I'm… I'm sorry for her, she… When Bloona gets big, she kinda gets…"

“Aggro?" Jane said as Anon paused to think of the right word. “Nah, Zeppo can be the same way. He usually plays things off until he puffs up, then he gets all A-type personality… y'know, you've got an AZC yourself."

“Aw shit, please don't let them wreck the store…" Anon grit his teeth as the scene developed.

“Ha!" Bloona laughed as Zeppo's pants gave out a moment later, and she spotted his featureless crotch. “No dick?!"

“Shit! Jane, did we leave my friendlies at home?!" Zeppo turned to shoot towards his partner.

“What do you think, Zep?! We were just going to the store! Why would you need your cock and balls at the friggin' store?!" Jane put forth incredulously, her dark pigtails bouncing over the front of her shoulders as she gesticulated. Bloona continued to laugh, stumbling in place somewhat.

“...Did he say friendlies?" Anon asked Jane as another aside.

“Well, that makes one of us!" Bloona, as if giving into her zeppelin urge to expand, grew and shot far above the incredulous Zeppo. At first, her bust broke free of her poor blouse, laughing as her now ginormous tits bounced, as if threatening to bonk the smaller Zeppo on the head with them. Now her hips were practically caught between the shelves, taking up the entirety of the aisle and her impressive aralatex ass squeaking against it, her skirt surviving but reduced to a weird ring or little tutu stretched across her waist. In this form, you could get a good glimpse at the jet intakes for her unique leg engines, which gave her a bit more thigh-profile width. “My human is good for all of this!" She flexed and motioned down to her whole personage, and despite her maximized body type being well rounded and voluptuous, her biceps dwarfed the musclebound Zeppo's beneath her. Bloona eyed down to her exasperated owner with lustful eyes, making a kissing face and winking at him. He just covered his face in an embarrassed blush.

“Is that so?" Jane was far more amused than impressed with a little grin, eyeing Anon with a laugh in her throat. “Good for all that?" Jane's eyes went up and down Anon- looking down at his lower body for a second or two too much.

“I mean…" Anon coughed, scratching his neck. “I do my best."

“In fact…" Bloona suddenly lunged forward, her butt squeaking loudly against the shelves as she grabbed Zeppo, smushing his arms into his sides. “I could eat you up, you know that, you little pipsqueak?!" She grew more and more excited, beginning to drool, fully in the throes of her ego. Her size made her feel just so unstoppable, so invincible at just about twelve feet tall and almost as wide. “Anon! Should I do it!? Show this little runt what he's good for?!" She offered, practically begging for her master's condonement, licking her chops voraciously.

“Can you not let her vore my boyfriend without his consent?" Jane muttered to Anon, not entirely concerned. Zeppo was far less unbothered, of course, worming a hand free to hold Bloona's maw away from himself in terror as she laughed and snapped her blimp jaws at him.

“Alright, Twenty-Seven? Hit her," Anon called out and Bloona's egomaniacal persona shifted, hearing the number-name of the security bot currently parked behind her massive ass, and she was suddenly struck with fear- before she was struck with an EMP stunner, her body convulsing as she was shocked, dropping Zeppo. Her endoskeleton flashed visibly, deep beneath her stretched, ballooned skin as she was lit up with the stun gun, before she collapsed, unconscious and beginning to slowly shrink back to her nominal form.

“Aw, jeez, thanks buh-" Zeppo could hardly get back on his feet before the security bot advanced and jabbed that stun baton right under one of his thick pectorals, similarly knocking him out cold as well.

“Attention shoppers. The peace has been restored. Please resume your browsing." With the bot's face-screen turning from generic clipart of a policeman to the image of a yellow thumbs-up, 27 turned around to go, but not before stopping by the halfway-deflated Bloona, her features still thick and voluptuous. “I like ya cut, G," It proclaimed loudly before that wand of his extended and slapped her on the ass with it with a resounding bwoong, leaving the two humans standing over their now nominally-sized balloon androids passed out naked on the floor.

“Damn, just bought her that blouse," Anon huffed. "At least her skirt didn't go." He walked forward and picked Bloona up, placing her in the cart, taking off his sweatshirt to drape over her well-defined, yet featureless chest, nipple-less or not as it was. Of course, beneath Anon's sweatshirt was a bright pastel display of big-breasted cartoon women on his shirt, to which Jane immediately swallowed a laugh at.

“Oh my god, dude, Cutie Pie Ameratsu?" She uttered, immediately recognizing the anime, and Anon looked down, taking a moment to realize what he was wearing. “That's classy, dude."

“Aw, shit, forgot I was wearing this," Anon grumbled of his Nipponese anime apparel while Jane quietly laughed. Anon turned to look at her, blushing, while she hefted up Zeppo in her arms, to which Anon noticed how small he was now. His nominal form must have been less than five feet tall, even standing on the balls of his digitigrade feet. “Is he a size small?"

“Yeah."

“I'm starting to think I should have gotten a small."

“Eh, don't look at me, I didn't buy him," Jane rolled her eyes, and before Anon could ask The quiet conversation was breached by a sharp gasp, Bloona jolting up from where she lay in the cart, breathing heavily, eyes wide as she clutched the sweatshirt draped over her, conscious again. Bloona looked down at herself, back to nominal form, and the scraps of her shirt barely hanging from her arms, covering her bare blue chest with the sweatshirt.

"Aw, geez, I totally hulked out again, huh?" Bloona winced, feeling the stares of the two humans glaring at her. "My… Ohh… My bad." She looked up a little, seeing a couple things knocked off of the shelves down the aisle, which 27 was now putting back up one-by-one with his extended arm. "At least I didn't wreck the whole place this time."

"Damn, she's usually out longer than that," Anon noted.

"Does she do this often?" Jane asked, Zeppo still softly droning in her arms, a hanging leg twitching in his sleep.

"Like I said, she gets out of control when she grows… Sometimes I have to sneak up and knock her out myself," Anon whispered, quietly displaying his own stun gun to Jane as Bloona was predisposed with cringing in embarrassment, a customer and their child passing the cart she was in.

"Mommy, can I get a big monster 'droid like that?" The little girl asked, holding her mother's hand. The mother winced a little bit, as if her child was asking about where babies came from.

"...Maybe when you're older sweetie." Bloona sheepishly smiled and waved at the two, who did not reciprocate her embarrassed attempt for social clemency. Bloona turned to look at her owner, sheepishly grinning, before laughing a little bit, seeing what was on his chest.

“Oh, flying with me is too embarrassing, but you'll wear that?" She commented on his shirt, going to put on his sweatshirt before climbing out of the cart, brushing herself off.

“Shut up, it was all I had that was clean." Now, it was Zeppo's turn to gasp awake. He looked down at himself, before remembering what had happened. He immediately glared at Bloona, who blushed and grinned weakly.

“Heyyy…" She waffled . “I'm, uh, I'm real sorry about… All that." Zeppo took a big breath in through his dragonlike nostrils, closing his eyes, before sighing strongly.

“It's all good. I get it." He grimaced, saying it as if he didn't really mean it, but still trying to mean it. Anon and Bloona were expecting a lot more of a reprimanding, of course, but Jane didn't seem phased by Zeppo's sudden shift into calmness. He jumped out of Jane's arms, standing there. Jane wasn't tall by any means, though she was quite stocky, and yet in this form Zeppo came up to her breast height like this android was her adolescent son. Slowly he grew once more, extending his endoskeleton but not inflating, getting taller and skinnier before he was soon just under a head taller than his girlfriend once more- his preferred size, though not his designed default.

“...You want me to go get the spare change of clothes in the car?" She asked.

“Nah. Don't care." Zeppo's indifference felt like a put-on, though he seemed to stick to it as he shrugged at Bloona. Bloona's body let out a subtle hiss as she too grew some, as if put upon by Zeppo's gain in height and not wanting to be outdone, but Anon quickly elbowed her in the side and shook his head at her.

“Look… I'm sorry for what Bloona started," Anon put forth. “Let me make it up to you guys. Want to go clothes shopping here? We can replace what got ripped up."

“I'm goo-" Zeppo tried to refuse, but Jane wasn't having it.

“Free clothes? Hell yeah," Jane cheerfully accepted. “C'mon, Zep, they're trying to be friends, and you're naked," Zeppo rolled his bright yellow eyes, tail whipping as he crossed his arms beneath his bare pectorals. The dragon-esque rubber android didn't know whether or not to be embarrassed at his current lack of equipped genitalia.

“Anon! You didn't tell me you wanted a double-date today," It was Bloona's turn to elbow Anon in the side and he sighed.
