I don't think I've said this before, but one of the things I find most interesting/arousing (both as a writer and a reader) in these stories, isn't necessarily the gentle/violent dynamic of the giantess/shrunken (wo)man relationship -- it's making a convincing giantess or goddess out of the 'regular'/'next-door' kind of girl.

Those little details and touches (the gum wrapper, stains on the pillow, cleaning out the ears, or smacking the lips after whispering, etc.) might seem unnecessary, from place to place, but they're essential for me in getting across to the reader that this girl, in many ways, is average and could be anyone -- she has these endearing imperfections, but she's also a giantess/goddess. I love that part about this fantasy. (And I see some of that in your story, too. That's what I meant about 'intimate', by the way.)
