I had been friends with Bill since first grade. When we got to eighth grade, we really were at that point where we knew too much about each other and each other's families.
Bill was an African American and was about 5'8' at the time. We both played basketball together. The only thing that we had never talked about was masturbation.
One February night when I was over at Bill's house, he brought up the subject, and after some in depth talk, he stripped down and showed me his huge 7 inch penis.
Then I stripped down with my penis as hard as a rock. For the next hour or so, we laid together and masturbated each other. From that day we did it several other times, however, girls quickly became a huge factor in our lives. We are still friends today with wives and children.
