Should I make a move?

I was sitting on the couch with my girlfriend and I was holding her hand, it was a weird angle so she let go of my hand and pressed it into her inner thigh up.... Higher than normal. I was pleased as this was the first time something like this had happened. But I couldn't do anything more as we were surrounded by her family. We were called to dinner and when we came back every time I put my hand on her leg, not too high up, she moved it. What is she thinking what should I do?
