Sounds like an essential sub idea, really good.

I remember reading in another thread ("First submissive thing you did?") this girl told us how one day at school, she'd gone into the boys' change-of-clothes room (sports class) in a deep and revealing tee, after she'd locked her hands behind with toy police handcuffs and fixing a piece of paper at her chest "Do anything you want to me, I cannot protest". That one sounds a bit better than the real thing, but a sizzling fantasy.
