She had just about been ready to slap herself, throw out the empty vial and walk away when an odd sensation began to ripple through her body. It started in her throat, permeating into the muscle, before rapidly spreading. Warmth was the strongest part of the feeling, but there was something else, a... seperation? Like layers of something being gently tugged apart... except that something was her.The liquid, whatever it had been, it was... melting her?
The thought that she might have consumed some sort of fast-acting flesh-eating bacteria was quelched by two things. One, she wasn't toppling over in immense pain nor bleeding profusely inside her own throat, so it couldn't be something destructive. Two was her reflection: starting at her mouth, she could see a very slight change to the pigmentation of her skin. She'd always been a pale sort of girl, but now the skin around her lips was very lightly tanned, and that discoloration was spreading rapidly.
She was enthralled for a moment, watching as the tanned skin spread over her epidermis, smoothing out every little wrinkle along the way. So much so, in fact, that she almost missed it as her lips changed color too, darkening into a bold shade of crimson, as if permanently affixed with lipstick. The change in coloration brought with it tingling, but the next change was accompanied by a buildup of pressure as her lips grew. Not to any massive degree, but she could feel them plumping up just a bit, becoming softer - her skin, too, was becoming almost silky to the touch.
The changes to her skin progressed up her face rapidly, soon crawling right up into her hair. Whereas her skin had been tanned by the changes, her hair was lightened, at first rapidly shifting to a shade of brown before brightening up to a full-on golden blonde. The straight locks lengthened themselves, reaching down to her shoulder and taking on a wavy texture that perfectly framed her face, accentuating her her features. As she took in her own face, Terri couldn't help but think that with all these little changes, she looked... beautiful. Like there'd been some pretty girl in there, and the changes had wiped away everything obscuring it.
Of course, her body was far from done with the alterations. On the contrary - she found herself letting out a little gasp of excitement as the modifications to her skin plunged down to cover the rest of her body, bringing with them a pleasant tingle that set the more sensitive parts of her anatomy abuzz. She found herself biting her newly-plumped lips as the little bit of fat that had clung to her arms, legs, and gut started to disappear. She could feel it burning away, leaving behind a mostly slender frame, save for the bubbles of flesh that now seemed to be trailing up and down her skin.
The purpose for these bubbles became evident as they began to collect at her chest and rear end. The feelings of outright arousal were now impossible to deny as she felt the fat and excess flesh melting into her breasts and ass, pushing them outward to strain against her bra and underwear. Frantically she ripped off both articles of clothing, tossing them to the floor in order to admire the way her reflection was filling out. With every little bit of mass her curves gained, she found herself driven to further heights of excitement, both hands now resting under her breasts to squeeze at their new mass.
It only stopped when she had no more fat to redistribute, but by then, her body had reached breathtaking proportions. The size of both her top and bottom were considerable, but they were still just barely in the realm of being reasonable - as large as they could get while still being perfectly proportioned for a girl her size and stature. Fit yet curvy, rather than a stick with ballons taped onto it. The same proportions as... as Anna, she realized. The hair, the tan, the curves, they were taken right from the campus bicycle, blended perfectly with her shorter stature and distinct facial features. The best of Anna mixed with the best of Terri.
The realization of how truly gorgeous she'd become slammed into the girl with truly orgasmic force. A delighted moan escaped her lips as she dripped with liquid joy, her voice ever so slightly deeper, more sultry. For just a moment, she worried that her mind might get lost in the erotic feelings coursing through her, but she could still recall her schoolwork with ease. Her mind was intact, now placed in a body that was sure to make Aubrey's jaw drop when she walked into class tomorrow. She was sure of it- all that self-doubt had vanished, replaced by unending thoughts of all the things she wanted her redhead crush to do to this incredible body.
