Tabitha had been uncomfortable in her clothes all day.
The beautiful, ultra-buxom 30-year old teacher was looking down at the shelf of her chest, white fabric of a "conservative" blouse stretched egregiously over her 52-inch balloons, the many darts and extra stitching all tensing nearly to bursting around her heavy breasts.
She was looking down at a golden chain. Its little heart locket had fallen into one of the gaps separated between her buttons by her overabundant cleavage, poofing and popping up regularly as she breathed and shifted in her uncomfortable clothes, filled to the max with her ripe brown flesh.
She looked positively indecent, she thought. "But what are my alternatives except for looking like a bag lady."
She sighed, sealing the lockets fate as she tried to pull her royal-purple powersuit away from her waist, in order to de-emphasize the contrast between it's waspish dimensions and her phenomenally overdeveloped shelf of a chest.
"Those boys and their superheroes." She thought. "It's so American. I just don't get it." But she was glad for the fact that every other male eye wasn't popping her way every five seconds.
Unobserved, she indulged in a little pride, wrapping her slim fingers almost all the way around her waist. "Still in my twenties." she thought, with a little smirk. The position thrust out her chest and made her boobs wobble. She felt herself bounce in her seat a bit on her super-pneumatic ass.
"Lord knows this body does wonders for the boys attention spans, but it's so hard to find clothes that fit." Tabitha's mind drifted to the simple shawls of her family back in Africa. She came from a line of women that were not easy to fit into American clothes.
She gave up with her struggles, sighing again, which pressed out her industrial-strength bra into the stretched out and misaligned darts of her bulky blouse. She settled into her chair, feeling her thick, purple-clad rump and hips squeeze out into the dimensions of the cheap plastic shell.
She looked up just in time to see a beam of green light from somewhere on the other side of the auditorium shoot down and envelop the Hulk, standing sullenly at the back of the other superheroes arranged before the audience. The Hulk started to shrink, suddenly and rapidly, a confused look on his face as he wobbled and deflated like a balloon, eventually collapsing down into the feeble Bruce Banner as the large bubble of green light around him grew bright and then seemed to zip back along it's beam with a bright, retractive burst.
Some of the light caught on Tabitha's golden chain, spreading a scintillation of the hulk's energy out across her protruding front, popping a stitch in her bra and shoving her tits out an inch further, drawing the buttons below the balcony of her tits even tighter. She returned her attention to her uncomfortable clothes, staring down at the bulging brown mounds of her cleavage, now spreading out the gaps between her buttons, drawing stretch-marks like spider-webs across her balloon-taut front.
She was briefly aware of the increasing commotion in the room, a loud argument between what sounded like a scientist discussing something with, his wife?... and... she couldn't stop staring at her boobs, already gigantic, going larger, when ZAP! the beam shot off from Ben's gun, bounced off Thor's hammer, held high in the air in his confusion of Banner's predicament, and POP! one of the buttons trying to restrain Ms.Obunde's abundance went flying in the same direction of the oncoming beam, the tiny white button falling to the ground green, and the size of a saucer, as the ray slipped neatly into the ripe, bulging gap of brown cleavage that had been exposed by Tabitha's uncomfortable clothes.
She started to grow.
POP! POP! P-P-P-OP!! Went the rest of Tabitha's buttons as those gigantic, oversized brown breasts began to wobbble and shaaake within the confines of her purple-power suit and white blouse. The tails of her shirt unnecessarily untucked themselves from her tiny, purple-cinched waist, where the belt was starting to creak from big, brown bubbles of muscle pushing their way out of her abdomen, pulsing larger achingly one at a time.
Her ass was bouncing around in the confining plastic chair like two purple, pumping balls, creaking the plastic as they inflated larger. and larger. and LARGER. Instantly cracking the chair in back, then on the sides as her thighs got in on the game and bloated out with huge chunks of smooth brown flesh.
To the casual, stunned observer however, it would seem like all this growth was merely to support her tits, which were shaking themselves larger and larger. Their bottoms slapping on her expanding thighs as they playfully bounced and inflated out two feet in front of her, then two and a half, then three, all in as many seconds, blowing up above her collarbone as her milky-chocolate skin started to darken to a deep shade of forest green.
CRACK! Went the chair, and RIP! went her purple power skirt as she collapsed unceremoniously on the floor, now shaking and wobbling all over, moaning loudly as she began to truly erupt.
The other heroes had gathered in a circle around her, expecting a new Hulk in their midst already, and the crowd also duly backed away to give the expanding teacher room to grow, her purple and white clothes now lying in tatters on her shuddering, expanding, prone form, having exploded off her body like balloons popping, not something that even happened to the hulk.
For while they were expecting a hulk-like transformation, then couldn't have guessed the extent.
One only had to look at the respective, untransformed bodies of Ms.Obunde and Mr.Banner to appreciate the eventual magnitude of the difference in their change.
For what most people did think about was that gamma interacted with DNA. Ms.Obunde's DNA was obviously aligned to give her a generous, some would say over-generous body, and the growth she was receiving, the eventual size she would achieve, were equally over-generous.
The big, big, green boobs that grew onto the frame of the frail Jen Walters on Tabitha Obunde were going to become as large as weather balloons.
Gamma interacted with DNA not like addition, but like multiplication. Few knew this, and as Bruce Banner quietly backed out of the auditorium, there were even fewer present that knew it, but Tabitha was figuring it out, she was a bright girl, and was enjoying the ride.
She was currently moaning, groaning, sighing and yelping. Her eyes clamped shut and her thick, thickening lips grinning, puckering and smirking, gasping wide in delight as her huge, forest-green body popped, bulged and grew in all directions.
From many perspectives now, only her muscles, her tits, and her expanding, somehow intimidating, darker-than-the-darkest-forest-green afro could be seen.
But most eyes were focused on her tits, which were growing faster than the rest of her, a LOT, and were each about as big as her whole body, growing one side, then the other, pumping and bloating up and out with abandon. Huge, inflating watermelons bigger than those at a fair, hooked up to a gamma pump that were shooting them higher and higher with supernatural size, each green, sweating jug now about the size of a refrigerator.
A bellowing moan was heard as two ink-green, immense nipples popped into prominence atop them, her eyes suddenly went wide and she shot her huge, growing arms up against her gamma-boobs, grasping as much of them as she could.
"Oh my GOD!" she cried. "My TITS!!" The bellow rattled panes of glass in the skylight up above and shoved many boners into the pants of all attendant that could achieve them through the fear of this uncontrolled, expanding, muscling-up beast of a woman.
Grabbing her now dark-green blobs as they blew up higher and higher, Tabitha felt her ass surge up off the floor, tilting her green, greasy, embiggening cunt up into the air and sucking her conservative white panties into the darkness there. She felt her back loose contact with the floor, but briefly, as her back involuntarily tensed and exploded with size, doubling in width and depth like a green power balloon and colliding back with the floor, cracking it as her tits just soared up higher in response.
Her shoulders were the size of Yoga balls now, and were clearing out chairs left and right as her tiny feet thickened and propped up into the air on beachball-sized green calves that squeaked as they bloated and dragged along the floor on her lengthening, tree-like legs.
"This feels AMAZING!!" Tabitha moaned through a feral grin. Her throbbing could be heard as she grinned and grabbed her tits, spreading out her elbows as her green flesh squeaked on the floor, flexing out her expanding mass and giving it room to grow.
Everything started pumping up even more rapidly. Her bones could be heard cracking and groaning as her muscles collided with one another in her growth. She had to be eight feet tall now, her afro pressing into the stage and her feet nearing the edge of the heroes, who had backed up further.
She "Mmmphed" and rippled her body. Then just spread eagled and let it expand. Her head disappearing as her afro pillowed into the stage and then crunched through it. Her body squeaking on the linoleum tile and the cracking of the wood heard as her head cracked into the bottom of the stage and it crumpled inward, further destroyed by her gigantic green traps. and wide, plug-like neck, thicker than her head.
Now muffled, yet somehow amplified by the echoing box of the stage, could be heard hear booming, expanding laughter.
Her huge green tits with their attendant, ink-dark nipples were bouncing high above the stage. Her still petite-looking feet, now as big as dogs, were twelve feet out in the audience.
She began to stand.
