Looking for a story

The title I remember was "Just a little thing," and the protagonist's name seems to be Shirley Winter

Can you give more clues?
What was the story about, or what happened in it.

It seems to be an article on the deviantart website, and the title seems to be "Just a little thing", but I can't find it.

More precisely, I'm trying to find the author of this story

I found it right away by searching (with Google) for Just a Little Thing Giantess.
