Humans leave the strangest things just lying around sometimes. Whether it's a city street or alleyway, forest or dirt road, they always seem to make their mark wherever they go. Even in scenic kanto, the occasional truck or cart loses a bit of it's payload.

	Even in the scenic viridian forest, strange human things end up discarded. Moving between the trees, enjoying the shady underbrush, a young pichu scampered toward something in the distance she saw shining. As she approached, an older pikachu was already there, sniffing at the odd object. It was big, shiny and had a big H E painted on the side of it. The pichu approached and glanced over it herself, the pikachu greeting her cheerfully. It seems the two mischevious pokemon would have to figure it out together.

	The two females ran around the tank, looking it from head to base. The pichu glanced at the odd round glass-shielded dial at the top, while the pikachu pawed at a small metal wheel on the side. The was a sudden hiss and the hose whipped about, causing the two to dive for the forest floor, covering their heads. Was it a snake? Some sort of creature? The hose whipped and hissed, swinging toward the young pichu who laid on her belly, head down and rear up taking cover from this oddity. The hose whipped toward her...

"P-PIII!!!"

...and found it's mark, the cold nozzle pushing into her rear. she scrambled to her rear paws, eyes wide and a blush along her muzzle. There was a uneasy gurgle inside her belly, which roused the pikachu's interest. She rose and an ear twitched..what was bubbling? Why was the hissing sound far off? She glanced toward pichu and immediately began to laugh. The pichu's belly was distended with something, she pawed and squeaked, but it wouldn't go back in! In fact, her yellow-furred belly only grew larger, swelling outwards as if she'd binged on berries. She glanced to the laughing pikachu and pointed to the tank, which the hose led to.

	It didn't take long for even pokemon to put two and two together. The older female pawed at the wheel when she realized it caused the hissing, but this only got a shriek from the pichu who began to swell faster, her belly feeling uncomfortably stuffed and resembling a puffy yellow balloon bulging out before her. The pikachu quickly spun the valve the other way with rapid pawing until the muffled hissing quit. Sweating and panting, the pichu gave a soft moan of relief and rubbed her belly with her forepaws. It made the blush across her muzzle grow, sending odd waves of...something through her..she was too young to have the urge to mate yet, but something about her sitution was bringing out new needs. She slapped her belly lightly with a paw and squealed, she pushed and rolled it like a toy balloon, her panting starting to quicken as one of her back legs twitched.

	She suddenly stopped, glancing over at the Pikachu and feeling like she was going to faint. The pikachu stared at her, knowing full well what was happening...but almost shocked she'd get that worked up over whatever had happened. The pichu felt ready to cry, whatever she felt, it was very embarassing. The pikachu tilted her head a bit and giggled, maybe the pichu liked it. Maybe she wanted more? Regardless, the pikachu found her predicament amusing! She looked like a human inflatable decoration. She tilted her head, placing a paw on the metal wheel again "Pikaaa?" she cooed, watching the living pokeballoon before her.

	Pichu paused, then nodded. If it really was okay, she wanted it! She could take in a little more gas and have more of those really good feelings.. there was a squeak of metal on metal and soon she felt the cool gas tickling up into her rear, causing her belly to buldge further, soon resting on the forest floor beneath her. She squeaked and squealed, pawing her swelling belly and closing her eyes, wriggling against her own bloated girth. The pikachu watched in a mixture of amusement and embarassment, pawing the valve open a little more with a giggle. The hiss built and the pichu filled bigger, giving a happily squeal and grasping her belly in her forepaws as her tail bounced and wiggled. Beneath her, her tight snatch grew slick and hot. She tried to wriggle her flat tail under herself, but couldn't. Oh, how would she keep the feeling going now?!

	Puffing and panting, the ballooning pichu looked for something, anything to ease the heat she'd swelled into, the pikachu pretending to look away, but giggling more at her embarassing predicament. She was so big and full looking! Her belly was nearly wider than she was tall! She couldn't think of anything more hilarious than that pichu swelling like a piece of ripe fruit. Well, until she heard a loud clank...

"PiiichuUUuuUUuuu~"

The younger pokemon had knocked the metal thing over and leapt onto it, vigorously humping the smooth metal cylinder with huffs and gasps, leaving a slick coating on it that glistened in the sunlight. The pikachu didn't know whether to be embarassed or laugh herself to death, barely muffling her laugher as she pawed the valve again, then again, listening to the hiss grow louder and louder. She laughed and rolled on her back when she saw poor pichu trying to grind the canister with how fast she was filling, looking more like a big bouncing yellow balloon. Her body gurgled and moaned as she filled larger and larger at a rapid pace, her grinding suddenly interrupted by a new, alarming feeling.

"P-pi..?"

	She glanced down at herself with concern and only saw a vast balloon of yellow before her, her legs puffy and spready to her sides. She wiggled her plump looking forelegs at her sides uselessly, eyeing the occasional buldging veins and stretchmarks on the surface of her hide, just beneath her fur. Too much, she felt so full, so horribly uncomfortably full. She moaned and wriggled again, but the pikachu watched her balloon with amusement, smacking her belly with a paw then laughing at the loud hollow THUMP! It caused the Pichu to squeal in pleasure and her nethers to spurt a little, her toes curling for a moment before the quivering pokemon eased up.

	She grew and grew, looming over the pikachu as she whined and squirmed, her tail slapping against her body a little as the pikachu watched her grow, tilting her head at her reaction. She eyed a stretchmark and pawed it. Another breathy squeal. She idly slapped at a buldging vein. Pichu nearly fainted, her toes curling again. Pikachu finally noticed her skin turning pink near the middle of her belly and ran a paw along the area curiously...

"PICHUUUUU!~"

	A sudden gush of her thick juices covered the metal thing below her as she reached a glorious first orgasm, her eyes rolling back as lids fluttered, the forest becoming a swirl of greens and colors to her vision..and yellow. The sudden change in color snapped her back to the horrible pressure, she realized the yellow, rumbling, stretchmark-covered thing before her WAS her. She squealed pathetically, wriggling her puffy legs. She was an immense blimp of a pokemon, her taut skin shining beneath her fur as beams of light from above landed on it. She realized the creaking and groaning wasn't the branches above now, it was her body. Her overfilled body.. tearily, she made a few grasps for the hose with her footpaw, but only pressed on her belly, causing more delicious, guilty, ill-timed pleasure as she shuddered.

	Pikachu was unaware of the predicament, after all no pokemon has ever got this big, what could go wrong? She stared at the whining, creaking blimp of a pichu before her, giggling and snickering at how absurd she looked. Suddenly, she groaned louder, giving the pikachu pause as she realized it was her. An ear wiggled as she watched the young pichu throb, gurgle, creak, whine and groan. She took a few steps back with a gulp, watching her quiver with pressure, a deep, endless grrrroooaaan nearly drowning out her whining...

"P-p..piii..c-chhuuu-!"

BOOOOOOOOM! Suddenly, the pichu burst asunder in an explosion of heat, moisture and flesh. Bits and tatters of her hung from trees and the pikachu found herself soaked in various juices. She gulped and looked around at the sloppy mess, the canister laying in the middle of it all and hissing it's last a bit too late. She glanced left, then right, before speeding off into the forest, making a mental note to stay far, far away from anyweird human objects she comes across from now on.
