I was at Silver Bells downtown with my family and this middle-aged guy standing right behind me kept brushing his hand lightly against my ass. The first time I thought it was an accident because it was crowded and there were a lot of people down there. But it kept happening and I just ignored it. He later put his whole hand cupped on my butt cheek and left it there. I probably should have moved forward or moved over on the other side of my mom but I actually was getting kinda turned on by it and it seemed safe since I was with my whole family. He was following the line of my panties with his fingers. I got a little nervous so at that point I shifted in front more so that he couldn't do it anymore. Later I regreted moving though. I looked back at him a few times and he just smiled at me.
