Lisa Gilmore was the nerdiest nerd there ever was: Keyword being WAS!

Lisa Gilmore was a very short and slightly chubby nerd (she could squeeze herself into a good swimsuit). She was being **** to work with the school's queen bee (more like bicycle she has to be sleeping with the principal or something with how slutty she is...) Beth Gino on a science project. Lisa rolled her eyes when she got the email from her "partner" who was off fucking some frat boy knowing she was most likely going to have to work on everything herself. She opens it only to get flashed by a bright pink light!

The flash faded to spirals and The spirals pulled her in deep, wiping away all thoughts of school projects or resentment. A warm, wet sensation bloomed between her legs as her panties grew damp with her own slick arousal, that 'love juice' starting to drip down her inner thighs. At the same time, her nerdy t-shirt and jeans began to shimmer and melt, the fabric re-knitting itself into something impossibly tight and pink. A microscopic, plastic-feeling halter top and miniskirt emerged, clinging to her changing form like a second skin, but they were far too small for her current chubby frame.

Her body obeyed the unspoken command of the new outfit. With a series of soft, wet pops and stretches, her flesh redistributed itself. The soft padding at her hips and belly surged backwards and upwards, inflating her ass into two perfect, jiggling orbs that strained the tiny skirt. Simultaneously, her modest chest ballooned outwards, heavy and round, stretching the halter top to its absolute limit, the plastic-like material digging into her newly plumped cleavage. Her skin tingled everywhere, darkening rapidly into a uniform, artificial-looking deep tan, the kind seen on cheap dolls or reality TV stars.

Her scalp prickled intensely as her mousy brown hair began to lengthen at an impossible rate. Thick, platinum blonde strands cascaded down her back, growing past her shoulders, past her newly inflated ass, stopping only when they brushed the backs of her knees. The texture changed too, becoming unnaturally smooth and shiny, like plastic fibers. Her face felt tight, features subtly shifting – her lips plumping into a permanent, glossy pout, her eyes widening and lashes thickening, her nose shrinking to a cute little button. A vacant, blissed-out smile settled onto her face, her mind utterly empty except for a fuzzy pink pleasure.

The transformation wasn't finished. That warm, wet arousal between her legs seemed to freeze suddenly, replaced by a creeping numbness that spread upwards and outwards like spilled resin. Her skin, already unnaturally tanned, began to lose its subtle pores and textures, becoming utterly smooth and cool to the touch – a seamless, living plastic shell. Inside, a terrifying hollowness yawned. Her organs, her bones, everything that made her biologically Lisa dissolved with a series of internal, wet slurping sounds, leaving only a vacant cavity beneath the perfect plastic curves of her inflated breasts and jiggling ass. A choked gasp escaped her glossy pout, but it sounded wrong, tinny and artificial. Her vocal cords had solidified, then reconfigured into a tiny, plastic voice box nestled in her hollow throat, capable only of producing high-pitched, doll-like giggles or breathy moans.

The numbness reached her limbs. Her fingers and toes tingled violently, then went utterly stiff. With audible, plastic clicks, every joint in her body – shoulders, elbows, wrists, hips, knees, ankles – locked into place, reforming as simple, molded ball-and-socket joints like a cheap toy. She couldn't bend; she could only pose. The final change hit her lungs. The air she'd gasped in moments before became trapped. There was no way to inhale again; her plastic chest didn't rise. The oxygen burned in her hollow cavity, a ****, fading fire. She felt the last molecules of her breath escape through her permanently parted, glossy lips in a faint, artificial sigh – the final exhalation of Lisa Gilmore. Her transformation into a living Barbie fuckdoll was complete, a hollow plastic shell in microscopic pink clothes.

For a minute, Lisa was awake. A flicker of something like panic sparked in her wide, plastic-blue eyes. "Hmm... Huh? HUH!? What happened to me!?" The tinny, high-pitched voice echoed strangely in the hollow chamber of her chest cavity. The sight of her impossibly large, plastic breasts straining the microscopic pink halter, the feel of her stiff, locked limbs, and the cool smoothness of her artificial skin slammed into her fading consciousness. The flash! That pink light from Beth's email! It had to be the cause. Terror, cold and sharp despite her lack of functioning nerves, surged through her hollow form. She had to get out, had to find help, had to reverse this!

Instinct screamed at her to run. She tried to lunge forward, but her body was no longer hers. The simple ball-and-socket joints at her hips refused to bend; her stiff legs couldn't stride. Instead, she pitched violently forward, her enormous, jiggling ass acting like a counterweight she couldn't control. With a loud, plastic CRACK that reverberated inside her empty torso, she slammed face-first onto the floor. The impact sent a jarring vibration through her hollow shell, making her inflated breasts wobble obscenely. Strands of unnaturally smooth, plastic-blonde hair fanned out around her head like a cheap wig. "Someone help! Anyone HELP! HE-!" she managed to shriek, the tiny voice box straining to produce the **** plea, the sound thin and reedy.

But the cry died in her hollow throat. Behind her vacant, glossy eyes, the pink spirals from the email flared back to life with blinding intensity, flooding her vision. They spun faster and faster, invasive and absolute. They weren't just images now; they were a ****, drilling into the last vestiges of Lisa Gilmore. Memories of equations, resentment towards Beth, the feel of her old, soft body, the scent of library books – all of it dissolved like sugar in water. Her panic, her terror, her very sense of self, were wiped clean, erased with the ruthless efficiency of a corrupted hard drive. The spark of awareness guttered and died, leaving only a perfect, empty void where a soul used to be.

The spirals faded, leaving her plastic-blue eyes clear and utterly vacant. The permanent, glossy pout curved upwards slightly at the corners. A soft, breathy giggle, like tiny plastic beads rattling, bubbled up from the voice box. Her stiff limbs remained splayed awkwardly on the floor, but her head tilted at a doll-like angle. "Hi! I'm Barbie!" the tiny voice chirped, bright and utterly devoid of anything resembling human emotion or history. The transformation was absolute. Lisa was gone. Only the doll remained, a perfect, plastic plaything awaiting its first command.
