The biggest one you've seen

A guy in lock-up / incarcerated in knew...called Mule.
He was muscle toned...over 200 lbs, about 6' 7" tall...very very black (skin complexion), bald, shinny head.
He didn't have or allowed a cell mate.
Two guards at a time would come to his cell at shower times and escort only him by his self to the showers nude in front of us and watch him.
Most of us would see him naked cause the guards didn't give him a towel or anything to put around him. The'd sometimes hollower out "Mule a-walkin"
His dick was so big, it hung and swung, you could see & hear it slappin against his thighs... he had to actually be 9-10 inches long and about 8 inches in girth soft...
And he walked tall and proud like he knew it.
They said he had about 13 inches when hard...and I saw it once hard when he was brought out the shower to dry off and marched back to his cell.
That man had one huge dick

Mule got additional time for raping another prison inmate so bad...that was in the cell with him, the guy lost his mind and tried to kill his self because of Mule screwing him to death like a bitch. We could even hear the guy cryin at night while Mule was screwing him.
Everybody was scared of Mule even the guards quite as kept always two on one with him and watched all the time.
But I think it was also known that the guards was also using Mule to do sexual things too some of the gay guys.
They took Mule out of his cell one night after lights out.
When the gaurds brought him back that morning, we saw he looked beat-up, bent down, could hardly walk as he held his gentials going back into his cell and in ankle shackels.
We knowed the damn gurads did something to him.
Well, enough of that...the man had the biggest dick I ever have seen...and I'm sure this was true for the other inmates as well.
The man could or should have been a black pron star with all rites.
By the way, FYI...many black guys in pron industry are selected ex-cons of some nature...it appears to be a prime place they have big dick meat.

only seen one bigger than mine, so mine untill recently seenin one that was bigger

When i was 16, a friend of mine(actually one of my best friends)(long story) should me his penis a couple of times. whenever we would change clothes or have sleepovers, or if i would depants him, haha. but i would always see it soft(it was huge by the way) and quick, but i wanted to see it big so finely i told him that my brother gave me a copy of a porno(even though it was really my parents porno but i didn't want him to know that)and we both got hard so i just pulled mine out and started wanking then he eventually did the same thing(after a while)and he was huge, i was actually ambarresed but he made it more comfortable by saying that we were almost the same(even though we werent!!!!!). and we still masturbate to this day but im a little bigger and he stopped growing so im almost close to him.

My wife says the largest she has seen was 10 inches. I don't ask guys to show me their cocks so I can't give a first hand account here.
