One day around 2 o'clock Kerry came home and kicked off her shoes and plopped next to me on the couch. She asked me to go to the cleaners and pick up something for her and as usually I said no. My sister must know I like feet so she kicked me gently on my leg and I obliged and went to the store. When I came back she was laying down and asked for a massage. She told me to massage under the shirt so I would get the skin. I dug my fingers into her skin and she was really enjoying herself. After a few minutes I got tired and stopped. We were sitting around and said she could really use a good foot massage. She put her foot on my leg and I started rubbing and than I removed sock as a massaged one foot her other foot was on my leg and by accident it wound up on my crotch. This immediately aroused me and I felt a slight bit uncomfortable hoping she wouldn't notice. She didn't move and all of the sudden I started feeling her rubbing my Dick with her foot. This felt really good and I continued her massage. She was laying down and put a blanket over my lap to try and cover up what was going on and she put her foot down my pants until I removed them.
