It's ok to touch her feet without asking or her putting them on your lap when you are close enough that you feel like you know each other. Eventually you will just know. It's an instict. I'm not a lee and I'm not into feet but my fiance plays with my feet a lot. Usually it's ok when I'm relaxed and watching TV or not doing anything important. It's not ok if I'm busy or trying to watch something I've waited all week to watch, or trying to read something important, or I'm busy, or I'm stressed (although foot massages are a great way to relax).
