Megan quickly noodled with boxes altering her and Jeff pretending she didn’t know what she was doing and hurriedly hit enter. Suddenly the computer disappeared and Megan grew concerned as Jeff felt sick as his head got lighter and his clothes disappeared replaced with a diaper no longer understanding how the toilet works nearly completely emptying him of intelligence. Jeff stared shrinking and deflating as he uncomfortably shifted making uncomfortable moans and grunting as his legs and arms became noodles due to his sister setting him on 10 and he finished shrinking down to 4’ a foot shorter than Megan smirked feeling her own transformation taking place the 11 year old girl’s costume changed from capris and a tshirt to jogging shorts and a tank top Jeff drooled almost completely absentmindedly as his younger sister posed in front of her invalid brother.
But by bit the little girl’s muscles sprang to life growing larger and larger she flexed her sizable yet still growing arms and legs becoming those of a light weight bodybuilder inching taller her wardrobe changed again becoming a spandex powerlifting shorts and a sports bra. Her muscular body surged ever larger and then again she began to panic having gotten greedier than Jeff she only set her height at 5’11” and her strength to 100.
Muscular 11 year old girl panicked as her muscles surged again she waddled as fast as her veiny ballooned out thighs would allow her barely making it to her room before another tingle staring into her mirror she saw a massively muscular girl looking back her B cups completely devoured by muscle tissue becoming little more than saturated pecs probably the biggest female bodybuilder in America half way done she tried to hurriedly hit the height bar up to nine foot six but before she could hit the button her chair broke during another spurt.
Unable to move the bizarrely muscular girl grew again becoming way bigger than any IFBB pro and probably any male bodybuilder TWICE her height. Little did she know she was only at what Jeff set it at when his bran functioned. The abnormally huge muscles began rising higher to demigod levels than her head as her saturated barn door pecs rose to her nose Megan hoped it was over rendered virtually immobile as her biceps and forearms were at a size that made her arms her arms firm and saturated oversized thighs rested over knees atop pumpkin sized calves. Megan began to whimper lifting her back just to be met with a thud.
The massive 11 year old girl began to sob when she heard a tap at the window, it was her Rory who would sneak in to her room from time to time. She yelled loudly knowing her cries are muffled by her muscular pecs. Luckily the window was open and Rory began coming in almost to fall out of Megan’s window.
“What the fuck happened to you!?” Megan focused hard working through the muffles of her veiny pecs. Rory looking at her computer saw her settings and hit enter leaping back from the floor bound Megan her bones heated up as Rory watched in amazement as the young not so little girl slowly grew taller spreading out her massive muscles incredibly stiff the massive girl barely got up looking silly in her tiny room. Nevertheless Rory was terrified and ran home since his childhood friend had become more taller and muscular than normal humans typically do.
The massive began banging on the tiny keyboard with her massive hands the mistake runs in the family apparently. Suddenly after seemingly getting nowhere a garbled error message popped up: }^[}*^it u override? Y/N trying her hardest she pressed yes suddenly she grew even taller and her room and the CHRONIVAC had disappeared the massive girl cowered naked in a large cave on the outskirts of town. Heating up with changes Megan worried and rightly so as her face grew masculine and unkept as her muscles gave her abnormal hormones levels like testosterone made her jaw and nose thicken, hairline raise and her once light alto voice violently crack to a deep baritone the husky girl cried her deep sobs echoing throughout her cave of exile.
