Helen was standing in front of her full length mirror, wanting to admire her body before she started the day. She wasn't particularly the narcissistic kind of person, but this morning, she wanted to feel free from the comfy confines of her clothes and enjoy feeling her exposed skin enveloped by the air unobstructed, oblivious to the fact that she would be able to see her changes in full view as the reality cascade revealed its first of many changes.
In this case, her changes would become the template to how everyone else changed in the world. Her shifting mind would have been honored to be the first changed and to lead the changes if she wasn't ignorant to its existence.
Her admiration of her body became more sensual as the cascade began, making her rub her hands all over her body as though she were posing for erotic nudes, slowly and lightly tracing her fingers over her legs, hips, waist and arms, outlining her body as it became hourglass shaped. Her figure remained even as her boobs receded before her eyes, even rubbing her hands over the flattened breasts like nothing was wrong.
As her hands lowered, her pre-cascade self would have expected to feel the soft lips of her vagina, but now she sensually drew her hands over their swelling forms as they began to expand into a male genitals, tickling her smooth skinned balls and tapping the mushroom shaped head of her newly form dick, giggling at the touch and how cute her cock was!
