My wife once saw my buddy's cock, he was probably around 7.5" - 8", but also very thick. She told me that he was the biggest she has ever seen.
My wife and I were heading home from our vacation a few weeks and stopped at a truck stop to refuel and to grab something to eat. I had to pee, so my wife waited for me in the hallway.
As I'm finishing up, I heard somebody come out of one of the stalls. Then I heard whoa, whoa, whoa, whoa, along with a splattering sound. I looked over and there's this tall skinny black guy completely naked, taking a piss right in the middle of the floor while swinging his cock around like a helicopter. He's between me and the door, so I'm like FUCK and back into the far corner to avoid being pissed on!
About the time he stops pissing, a police officer comes through the door, looks at the naked dude, looks at me, then radios for his partner to come in there. His partner, who was a really cute tatted up chick walked in and was like "HOLY FUCK!". Apparently, they had were already looking for the dude because he had hit another truck while pulling into the parking lot.
The cops threaten to taze the dude, so he decides he's going to make a run for it, takes about two steps and slips in his own his and goes down hard. The cops quickly pounce on him and of course the dude resist, but they are able to get him cuffed after a brief struggle.
When they stand the dude up, he has a raging hard on and tells the chick cop that it was all for her. Dude had tried flushing his clothes down the drain, so they wrapped him in a towel and took him out to the squad car, and he was ultimately taken away by ambulance.
When they took the dude out, my wife was still waiting for me in the hallway, and she said when they walked past her, he stopped and thrusted his hips in my wife's direction and asked her if she wanted to fuck? She said he was still very clearly hard up as it was tenting the towel out. The female cop slapped him in the back of the head and told him to move on.
The funny thing is, the dude was like 6' 2" but probably only 120-130 lbs... but had a big, long fat cock. It was 6-7" limp, and probably 9-10" hard... I was telling my wife that when they stood the guy up, and the female cop notice the size of his junk, she made an OMG face... My wife said "I bet, it was a monster!"
