Just as the Fairy looks to be ready to speak, you decide to make a split second decision due to factors you can see coming, namely you are shrinking and she is growing.
And so you bolt, even at your smaller height you try to put some distance between you and the growing fairy as she seems to just stare in disbelief, as if expecting a different response.
Your feminine crotch burns as you pass by trees, your size now too small to be of any use running as you duck behind a tree, still shrinking as you drop into the grass to hide.
Your body has been shrinking in more ways than one. Your masculine figure has outright crumpled away into a feminine figure and small breasts wer pushing off your bare chest. Naked you got a full view of your sylvian self, at least from looking down. You didn’t have wings, but you were fairly sure you were almost completely a fairy at this point.
The ground quakes as you looked around in fear, nothing a hole in the tree roots and ducking inside quickly to avoid sight.
For several tense moments you wait, your back aching as you hear grumbling outside, and shifting in the grass. You bite your tounge to keep from screaming as wings erupt from your back, completing your transformation as the rumbling continues... but gets farther and farther away.
You wait, for a few minutes, before deciding the coast was clear. You may have just lost your humanity... but you’ve probably just escaped an even worse fate.
