Grow some more

Your legs fail momentarily, as another surge of growth propels you up, like Alice upon tasting an 'Eat me' cookie. This happens so quickly that your head gets knocked against the ceiling, and you stumble down on your butt.

Sophie: "Whoa-UH!"

Fearing that another similar growth event could cause irrepearable damage to your home, you scuttle outside through the screen doors leading to your backyard. Now's a good time to gather your thoughts and take stock of the situation.

The second-floor windows of your house are almost level with your face. That means you must be almost 15 feet. Your proportions have grown with you - you're still nicely rounded and curvy. However, your clothes have not. Your bra at least seems to have taken its leave. Peering around nervously, there don't seem to be any nosy neighbours about.

Sophie: "God fucking damn, what'll I do if I grow any more than this? I don't want people to see me naked, I'd be embarrassed to ****!"

But then, as if hearing your pleads to reverse your magically granted transformation into a giantess, you are bestowed with salvation: a power which will solve this issue.

You intensely focus on being small again. You don't want to grow indefinitely, until you crush the Earth between your boobs or something stupid like that, so siree! Thus, simply by **** of will, you begin to shrink.

Only after regaining your previous size and vacantly staring down upon yourself in disbelief do you realize just what this entails. Feeling experimental, you consciously toggle your size between seven and five feet.

Sophie: "...I can control my own size!"
