My Bimbo Academia (Expansion) 1- Uraraka

Original Story by SNAKEBIT1995 used as an outline: https://pastebin.com/0wLjrfYx

The halls of UA were filled with the hustle and bustle of students and faculty headed from class to class, each of whom seemed to wear the neutral expression of one following a well-established daily routine. That is save for one girl who's expression was one of concentration as she walked counter to rushing crowd's pace, carefully working her way through them to her next location. Occasionally even pausing entirely to allow exceptionally congested hallways to thin out, much to the annoyance of those trapped behind her.

"Why don't you get a move on Ashley, those ugly cow tits can't be that heavy can they?!” Such a rude comment from a fellow female student was, unfortunately, not a rare occurrence for the poor girl. Her obvious lack of self-confidence as well as the two massive watermelons jiggling freely upon her chest, barely constrained only by the horrifically itchy and thin white dress shirt that's so full to busting with soft boob flesh that ample amounts of cleavage can be seen between the stretched apart buttons, made her an easy target for any malicious students looking for an outsider girl to mock. The facts that that her exceptionally gifted mammaries have prevented her from wearing her UA uniform properly with her jacket hanging open and that she is an exchange student from America only serves to make her that much more easier to pick out from a crowd.

Unable to find the will to turn to directly respond to the girl yelling at her in the face of the creeping lump in her throat our busty girl manages to only mumble out a submissive response, "N-no, I'm sorry. I'm going." Despite how such insults are levied at her regularly they still cunt the young bimbo fairly deeply. Desperately fighting back tears that are rapidly building up behind her eyes she lifts her dark rimmed glasses and attempted to massage them away, luckily to much success.

With the threat of outright sobbing in the middle of a crowded hallway successfully abated, Ashley finally matches the pace of the surrounding students and no longer waiting for particularly crowded halls to clear out. Soon reaching behind herself past her well-endowed ass to her lengthy blond and pink ponytail to nervously twiddle with her hair as the reason for her hesitation to walk fast in a dense crowd becomes obvious to all onlookers.

As evidenced by the unmistakable outline of her nipples against the thin fabric of her shirt our big-tittied nerd girl absolutely hated wearing bras, and panties too for that matter. While her incredibly comfortable, and incredibly undersized for someone of her build, blue pleated skirt just barely hid an ass that was equally as juicy as her chest, where the slightest breeze or bending over wrong would reveal all of her bottomless glory to the world. Her top was even less effective. Each swift heavy step sending the remarkably heavy bountiful orbs that bless her chest bouncing and jiggling, attracting plenty of amorous male attention as well as making it impossible to avoid bumping into other students with her rather gifted anatomy.

In truth, she would normally love the stares from boys, the way their heads bob with every one of her steps and the way that their pants conceal just enough of their rock hard budges to allow her imagination to run wild with the different sizes and shapes their cute cocks might have, it all sends her already active pussy into throbbing lubricating overdrive. It is quite a shame that she only knows what very few of them actually look like. She would likewise also normally adore when her hefty breasts collide with a fellow student, the shock-wave of impact rippling through her sensitive flesh forcing her to bite her bottom lip to stifle moan after moan that threaten to escape her throat.

However, undercutting and ruining all of what would normally be her lusty fun are the ever present thoughts that she is giving her tormenting classmates a lot of ammo. Already playing inside her is future mocking about rubbing her tits on every boy in school hallways and the insults of being an American slut are likewise ringing in her ears and bringing a deep frown to her overly plump fleshy pink lips.

Of course her mind is unable to remain distracted from the throbbing arousal between her legs and on her tormentors for long, especially with every new bounce, bump, stare fanning the building flames within her needy loins. It builds and builds until it reaches a point that she has to practically hold her hand back to prevent herself from shoving it up her skirt to tend to her excited cunt right here. In an attempt to prevent any unfortunate wanderings of the limb she soon finds herself obsessively scratching the front of her thigh, this only marginally helps her wet hot problem.

With a steadying deep breath the top heavy girl tries to turn her mind away from thee warm bodies colliding with hers and put her focus elsewhere, to the source of her overly lusty proclivities. Indeed, she was not always the barely self repressed bimbo who constantly fought against the urge to fix herself. She used to be a regular girl, greatly delayed puberty not withstanding, with aspirations of managing a hero agency until her late to bud quirk finally blossomed, one she has named Bimbofication.

From what little information she has gathered from her short time with with the quirk, she knows that it has transformed her into a bimbo through the use of some kind of energy that her body constantly generates. This energy builds and builds within her body until finally her body is full and it releases itself causing changes all throughout her being. These changes being both physical, with her breasts, ass, and overall body shape filling out more and more along with greater sensitivity, and mental, with a general increase in the sluttiness of her thoughts which include a fanatical love of the male form and anatomy alongside an absurd libido increase. So far she's counted five charges that have danced their lewd dance through her body at this point, with each one coming sooner than the previous.

Ashley was fairly swift to visit her doctor after the first round of changes fearful of what was happening to her body with her quirk, but her doctor was rather quick to dismiss her, simply putting the changes down to her finally starting puberty after a blood test showed elevated hormones consistent with it. "Nothing out of the ordinary," she said. The stacked girl scrunches her nose at the recollection of that particular memory, nothing out of the ordinary indeed.

She relaxes the scrunch soon after however. While she was frustrated at the failure of her doctor to help her out she has gained a new person to look to regarding her quirk issues, that green haired cutie in class 1-A. It was no secret, especially after the sports festival that every time he used his quirk his body was destroyed, and yet, he recently managed to earn his provisional hero license without a single broken bone. If someone with a quirk like that could learn to control it alone, then there's no reason why she shouldn't be able to do the same with her's, especially when it doesn't even harm her.

Speak of the devil and he shall appear, an all too familiar pressure in her chest harshly rips Ashley from her distracting trip through her memories and back to reality. It is the unmistakable building pressure of a charge of bimbo energy growing within her, concentrated to a pulsing small orb buried deep in the middle of her chest.

With every rhythmical pulse the sphere of energy expands further and further increasing the pressure within the nerdy bimbo's chest forcing her breathing to grow rapid and shallow. Fearfully glancing downward towards her chest, but above where most others' attention would focus, she beholds the dreaded pink light that only she can behold shining through her shirt and tie. Unbidden by the poor girl, Ashley's lust addled imagination constructs a paranoid, and amorous, scene of the potential outcome should this recent charge continue unabated.

Immediately following the pink power seeping, yet again, into her luscious curvy frame she grows, but unlike the previous changes the growth is not exclusively focused on her sexual characteristics. Indeed, the energy works its way far deeper into her body than before, snaking its way through every crack and crevasse leaving nothing untouched all while transforming itself into additional mass that is left in its slithering wake.

The explosively expanding bimbo could not help but smile lustily as her eyes drink in the sight of all the hot boys around her that she is rapidly raising above. They likewise stare back at her with smiles of their own, but these were of anticipation because as the blond nerd swelled her clothing did not.

Weakening, her fabric did its best to hold back the tide of surging soft beautiful flesh but they both soon wavered in their diligent service of decency. The first to fall was the shirt, stretched to the limits as it was by the girl's gifted bosom to start with it was simply no match for the additional girth. With the loud ripping of multiple buttons failing, the over-stressed shirt rips dramatically opens to expose Ashley's heavy bouncing, yet still inexplicably perky tits.

The imaginary skirt fared much better under the incredible strain of the bimbo's growing butt and hips.
