I love to hear about family matters.
This happened to me when I was 11: My family went to my aunt's house for the day. When we got there I went to the basement to find my cousin Nate who is 13. When I walked in he was jerking off.
I asked how it felt; he said good. He asked me if I ever played with myself. I told him that I had but nothing ever happened. He said he would jerk me off but I had to jerk him off after. I quickly agreed.
So I pulled down my pants and sat in a chair and he began to jerk me off. It felt so good that in about 2 or 3 mins I came.
He said it was his turn so we switched and I began to jerk him off. After about 10 mins he pulled my face in to his penis and cummed all over me. We kept taking turns for about 2 hours.
