Do large endowments or big balls run in the family? You've probaly seen your brothers at some time, and maybe your dad. So, do they have a similar large size as you? Is size genetic or just the luck of the draw? I'll start: Yes, I've seen both my older brother's and my dad's cocks. No surprise there probably. Now I had seen my older brother's erection several times, since we shared a bedroom. He liked to brag about it when he was a teenager, and then I checked it out and yeah he did have something impressive. 9 inches. I know because he measured it in front of me. I never did see my dad's erection, but I had seen it soft and it looked fairly small, but it was thick like a fat round sausage, with low hangin balls. So I don't know where my size came from. Maybe the men on my mom's side of the family who were all tall guys. I should give you my stat : 7.5 inch erection, with about 6 inches of girth at the base. So what about the other member's, do you take after dear old Dad?
