"Well" said Mandy sly, after some consideration, "I guess I can't just let you hog all the attention with your getup."
You were about to ask her what she meant by that, but before you could speak her form started shifting before your very eyes.
Her shoulder-length brown hair started to grow rapidly downwards, becoming wavier and messier as it did, but still mostly straight. The color started leeching out of it and before long it was pale and white. The white color didn't stay for long however, as a light lavender color starting to slide down her tresses from her roots, slowly transitioning to a pale pink at the tips of her hair.
Mandy brushed some of the long lavender bangs from her face, which you could now see was much different than before. Her pink lips had darkened, a matte black lipstick sliding smoothly along the surface. Her blue eyes faded in color, the outer edges of her irises turning black while the rest became steely gray.
Her eyeliner and mascara thickened as a gradient of black and soft lavender eyeshadow ringed them, making the new color of her irises pop.
Her already pale skin was fading further, freckles and discoloration smoothing away until she had uniformly unblemished, pale white skin from head to toe. Her left arm retained its pale coloration, while down her right black lines of ink began creeping down from beneath her very short shirt sleeve. They twisted and turned, undulating like serpents before forming shapes and patterns. Soon enough, her arm down to her wrist was graced by the images of thorny vines and colored flowers; pink roses like the tips of her hair, and sprigs of colored lavender like her roots.
On her right thigh and down to her calf, a pattern of moons, clouds, bats, and stars wove itself into existence.
Contrary to your expectation, Mandy grew in height, going from 5'3" to 5'8" in about thirty seconds. Her form became very slender without being waifish, losing bits of fat while still retaining pert rear and a fair pair of b-cups. She looked down at her fingernails and you followed he gaze to see them individually paint themselves black.
Mandy then peered at her clothes, a simple white t-shirt and jean shorts, with some white sneakers on her feet. "Tsk, tsk" she said disapprovingly, "this won't do at all."
Her white t-shirt retained its shape but darkened quickly to black, while some white splotches remained across the torso. These quickly coalesced into letters and numbers, forming the alphabet and 1-9. The words 'yes', 'no', and 'goodbye' below them. Above the letters the word 'Ouji' appeared.
Her jean shorts rose a little higher, enveloping the end of her shirt so that it was now tucked in. A black leather belt cinched firmly around her waist. The blue denim color bleached itself to a much lighter blue, almost white, then a pale pink color crept a few inches down from the waistline, slowly fading in a gradient to the blue color. The legs of the shorts barely went a few inches down her thighs, and the hems became frayed. On the right side of the front of the shorts, 3 embroidered flowers grew into existence.
Brushing her hair back again and staring at her feet with a look of concentration, her white shoes changed form and texture, becoming faux-leather and turning a pink and blue gradient color like her shorts, with black accents. Very quickly their shape took the appearance of Mondo Creepers, and a 1.5 inch black rubber platform shot your girlfriend yet higher above your now-diminutive form.
Mandy's socks started to extend, sliding smoothly up her slender legs. They faded to black as they stopped above her knees, and the image of white leg bones appeared along their fronts. You thought she might be done with her legs but, with the sound of shifting fabric, pale pink ruffle socks emanated from the Creepers and atop her black socks, creeping above her ankles before stopping.
Sizing herself up in a nearby mirror, your suddenly gothy girlfriend tapped a black-tipped finger against equally dark lips. "Hmmm..." she said, evidently not quite satisfied.
She closed her eyes, and you watched as a few more accessories dotted her form. A black blob appeared at the crown of her head, expanding to absorb part of her skull before shifting in appearance to being a black cotton beanie. A silver chain necklace slid around her neck, a small pendant depicting cartoon monster eye with wings dangled from the center atop her Ouji shirt.
A few colorful bracelets popped into existence around her right wrist, while a thicker, blockier bracelet that spelled out "MANDY" appeared on the left.
She pulled back her hair to show her ears, where two small plastic studs in the shape of black roses appeared. For the finishing touch, she stuck out her tongue, where a silver barbell pierced cleanly through.
"Thoo...?" she said, stopping to laugh and adjust her speech due to the new piercing.
"So, what do you think?" said your girlfriend much more clearly this time, striking a pose as she looked down at you.
You, twisted a foot idly again, this time with repressed excitement instead of embarrassment.
"I think you look hot as shit" you said. Both of you burst out laughing at how silly that sounded with your new girly voice. Your pastel goth girlfriend quickly recovered though, and stepped towards you with a sultry look in her steely gray eyes.
She leaned down and gave you a kiss. Stars exploded behind your closed eyelids as a veritable swarm of butterflies fluttered in your core.
She pulled away and looked at you again. "What now Ad...hey, what should I call you now? Your normal name won't cut it looking like this."
"How about..." you say, placing a finger on your soft lips and unconsciously playing with the hem of your skirts with the other hand.
"How about Lauren?" you say after some thought. "That was my Great Grandmother's name."
"Lauren. I like it" replied Mandy, "it suits you, Wren" she continued, sticking her tongue out at you, the barbell glinting in the room's light.
"So, what now?" you said.
"Hhmmmm..." she said.
