My wife is very shy and private. At least she used to be. Recently, things have changed a fair bit for us in a number of ways (full story elsewhere on this site) and she has gained much more confidence in herself and in her self image as a result. Anyway, yesterday evening the supermarket delivery guy got the full view down her low cut top as she bent forwards to pick up the groceries. She didn't have a bra on either. When he went back to collect more bags from the van, she told me that she had 'accidentally' flashed him. He came back and she did it again. This time I could see that he was having a good look and had even positioned himself to get the best view.
My prim and proper little wife is changing into a naughty little slut before my very eyes and it's wonderful.
