Girlfriend Likes Seeing Me Wearing Panties

When I was 23 I had a very fun and open girlfriend. I had always had kinky desires though my previous girlfriend thought every thing I suggested was to weird. I finally broke up with her for that reason. When I found a new girlfriend she loved to suck dick and started licking my ass, which was out of this world for me at time. I had a couple of male silk thongs that I wore in front of her to see how she would react. She loved them and thought they were sexy. One day a pair of her satin panties were on the floor and she saw me pick them up. She said why don't you try them on. I did and got hard right away. I just loved the look and feel of them, she told me how sexy she thought they were on me.
