Where To Start?

I once saw up my mother-in-law's nightdress. When the wife and I went round once and saw everything, this made me very, well, you know. She even saw me looking. To this day, I still get off on it. I wish I could bring it up when she comes around to see us and the wife has gone to pick the kids up from school. But I don't know where to start.
