The heat only seemed to increase for a while, and Rachel closed her eyes, the sensation overwhelming her for a minute as her clothes felt like they were constricting around her. She pulled off her t-shirt and struggled out of her jeans, falling onto her bed in only her underwear.
Eventually the feeling died down. Rachel sat up and got out of bed, feeling dizzy and slightly off-balance. The cool air felt amazing on her skin for some reason.
It suddenly occured to her how different her body felt, and she half-ran, half-stumbled into the bathroom. Looking at her reflection in the mirror, she was lost for words. It was still her, but so very different.
She was definitely taller, for a start. She didn't have a tape measure or anything to measure with to hand but by comparison to the room around her she seemed to have gained about half a foot. At some point her bra must have come off, revealing that her modest B-cup breasts had clearly expanded to what looked to be at least Ds. Similarly, her rear seemed to have gained some mass, her struggling underwear barely containing it. Her stomach had become toned, with near-six-pack abs, and her arms and legs looked to have a tiny bit more muscle as well. Her face was much the same as it had always been, though for some indefinable subtle reason it seemed prettier than usual, and her skin seemed smooth and flawless, and also somewhat... sparkly? Was that her imagination?
But the biggest, most immediately noticeable change was that her hair was now reaching the backs of her knees and was inescapably bright neon blue.
Rachel took a moment to just take the whole thing in. Ordinarily she probably would have had mixed feelings to some of these changes but right now all she was getting was joy and amazement. As she posed in front of the mirror admiring her altered body, she felt amazingly full of energy. She had an immense and sudden urge to go out and DO THINGS right this minute...
Rushing back to her room she tried to squeeze back into her clothes. Her T-shirt just about fit back on, though it now exposed a fair amount of her middle, but the jeans she had been wearing were now way too tight. Quickly borrowing a pair from her mother's room (in WAY too much of a hurry to ask for permission) and slipping on her shoes (thankfully her feet hadn't changed size), she rushed down the stairs and out the door.
