I think I was 8 when I saw my grandfather’s uncircumcised cock it was just like mine. He wasn’t my true Grandfather my Grandmother re-married and is why he was the only other uncut in our family that I knew of. I was delighted living in an all cut family brothers step brothers dads etc were all cut. so when My Grandfather gave me a bath he was surprised to see I had foreskin and said Mine looked like his and I asked him to see it. I played with it was so huge 8” fully covered and thick compared to my boy cock with long foreskin. I got older 18 and went to work cleaning houses with him and I asked to see and play with his cock again. We had lots of houses to clean and I’m sure we messed around in every single one of them before the summer ended. I was 6” thin then to his 8” thick. It was a great summer.
