The most I ever saw was a white man 6'4 245 maybe 38. he started at about 6 inches by 5 1/2 inches, it grew to 10 by 7 1/2. No hearsay, I made it grow, my mouth did... He told me at was 10 inches and I didn't need a ruler to see that was the biggest cock I ever saw face to face. He also cum an unusually large amount, more than I ever experienced. I didn't know a man's cock could grow that much. I didn't know it was possible for any man to cum as much as he did. Of curse I didn't complain, I was ecstatic.
