Mandy taps a finger against her lips, deep in thought again as she stares into the mirror.
You're still deciding whether or not you should change anything yourself, when she straightens up and snaps her fingers.
"Exactly!" she says to no one in particular, "let's turn it to 11 with this shit!"
You watch, nonplussed, as her form begins to shift yet again.
Her dark brown penny loafers change color, the leather turning black before the chunky heel starts to rise, lifting Mandy onto her toes. It climbs to five inches tall before the front part of the sole spews out an inch of black leather. They've become heeled loafers, leaving Mandy six inches taller than before.
Her socks remain white, but they extend further up her legs, reaching above the hemline of her skirt. The skirt loses its line of buttons, each one shrinking and sinking into the brown material, which quickly shifts into a light blue and plaid pattern. Vertical folds start appearing uniformly across it and the pockets fade away, leaving a blue plaid pleated skirt behind. The skirt shrinks heavily, stopping above mid-thigh, revealing that her white socks stop only two inches lower than the new hemline, little pink bows tied at their tops.
The shape of her button-up shirt shifts, bleaching itself white and becoming a soft cotton as it returns to the form of a t-shirt. Unlike her previous crew neck though, this one has a generous V-neck. The remains of the button up shirt's collar separates and alters, matching the same light blue plaid pattern of her skirt and becoming a choker that quickly ties itself into the shape of a bowtie.
Lines start to squiggle into existence on the shirt's front, swirling and moving until the words "Teacher's Pet" form, with the 'a' being replaced by a pink apple with a small bite taken out of it.
From the waistline of her skirt, two pink elastic strands form. They launch themselves upwards like party steamers, sailing over Mandy's shoulders before looping back down to fasten themselves to the back of her skirt's waist, completing her pink suspenders.
You look at her face, thinking she might be done, but her smirk tells you there's still more to come.
Your eyes are pulled down from hers as you see movement around her chest. The white cotton of her new t-shirt is pressing forward alarmingly fast, the pink suspenders strain, the V-neck pulled taut as her breasts expand, growing fuller and heavier. In seconds, her respectable B-cups go straight past C's and D's, right into the F range. You can see two thick, hard nipples poking very obviously through the fabric. Your expanding girlfriend reaches up and rubs a hand over one breast. She flicks the nipple lightly, causing her eyes to close while she throws her head back and moans softly.
Your jaw drops open at this and you gasp involuntarily.
Mandy opens her eyes and looks down at you. She smiles widely at you, and you can see that her two front teeth grown larger than they were before. When she closes her mouth, they are still visible, pressing into her soft lips. These lips aren't exempt from changes either, as with a soft gushing sound, they puff up larger and larger. They stop expanding, and pink lipstick begins to slide across their pillowlike surfaces. She licks them with a tongue that seemed a fair bit longer than was normal.
The freckles on her face mostly fade away, a but small dusting remains across the bridge of her nose, giving an unconvincing air of innocence. Her pale skin darkens slightly, a light tan sliding down from head to toe.
Mandy's hair begins to lighten past it's copper hue, strands of baby blonde intertwining themselves before slowly seeping into the rest of her scalp. The bright locks grew, lengthening down to rest atop her immense breasts. They didn't stay there for long though, as her hair lifted itself up and back, the white clip disappearing as pink hair ties pulled her tresses into two blonde ponytails.
As you focus back on her eyes, you notice they were expanding slightly as the brown leeched out of her irises, being replaced by brightest blue. Her then eyes pull themselves towards each other, giving her a bit of a cross-eyed look that seems designed solely for the sexy stereotype. A pair of modern, roundish black-rimmed glasses pops into the air in front of her face, falling cleanly onto the bridge of her cute upturned nose.
She snorts in laughter at your continued slack-jawed look as her frame starts to fill out with feminine curves. Her waist cinches inwards and she grows a few inches taller. Mandy's thighs and calves thicken with light muscle tone and a thin layer of fat, becoming much more shapely. Her rear expands, pressing out obscenely into the back of her skirt, raising the hem slightly and threatening to expose her privates to view.
"Tho like, what do you think babe?" she says with an exaggerated lisp, her voice now higher and sweeter. She gives a new twirl, balancing causing the bottom of her short skirt to flutter dangerously about her legs again, revealing her lack of underwear.
"Thith ith, like, thooo much thexier yeah?" she says with a wink, leaning in to the lisp.
You twist your left foot idly, staring at this almost pornographic representation of a college nerd. Mandy stares at you with fake innocence, not noticing as a small bit of drool slips out from between her bucktooth-parted lips. A strand drops, splashing onto her cleavage.
"Whoopth!" she giggles, sucking at her lips before licking them with her long tongue, "gueth I went hard on the lipth and teeth huh?"
She taps a heeled loafer, staring expectantly at you.
"Thoooo....?"
You're trying to hold back the warm flush of pleasure in your panties as you look at this beautiful bimbofied nerd standing right in front of you. It takes all your effort not to let your voice waver with need as you speak, a damp spot forming in your underwear.
"It's...hot as shit..." you finally admit, unconsciously breathing heavy and twisting your fingers together as you keep looking her over.
She giggles cutely at how that sounds coming from your girly little form.
"Well then, thall we go downthtairth babe?" she says, her eyes twinkling at the notion of adventure.
