My sister came home one day from school grade 6.
I was looking at pictures of naked granny’s.
she sat down and asked if she could look.
As she looked she asked if I had ever seen gran mother’s pussy! I said yes, she used to let me sleep with her and rub it for her.
As we sat and talked I began to get hard, and I placed her hand on it, she smiled and said she would like to see it.
As I took it out she pulled her panties down and said let’s do it!! So, we have been screwing since then.
