As soon as Rachael uttered those words, the outlines of the 20s woman and the girls grew blurry, smudged even. Then, as several unnaturally long moments went past, they began to change.
The woman's face began to slim down, as the beginnings of a second chin vanished completely, followed by her neck.
The girls' face, on the other hand, bulged-out, so their helmet straps began to practically cut into their cheeks.
Slowly, but not slowly, the woman's bulging breasts began to slimmer down, losing a couple of cup sizes, but at the same time perking-up considerably.
The girls' breasts, meanwhile, bulged-out even more, straining their bras and almost popping out of them, leaning downwards.
The woman's stomach also deflated, becoming almost completely flat, followed shortly after by her rear end that became a shapely bubble butt.
Naturally, the bellies and the butts of both girls blew-up and outwards, all but ripping their shorts and underwear apart.
Finally, the woman's arms and legs slimmed down, and became very shapely, while the girls' limbs began to bulge with cellulite.
And then... the blur vanished. Now, in the place of an overweight woman and two sporty girls stood a fine-looking woman, overshadowed by two hopelessly overweight girls dressed in ridiculously-looking tank tops and shorts, waddling foolishly on some roller blades, too shocked to realize what has happened.
The woman, however, did, and so she quickly withdrew towards the nearest clothing shop, intent of experiencing her new-found slimness to the max.
