In all my years I couldn't believe it!!
About 15 years ago I was in Florida for a convention and after it was over I decided to get some sun at a nudist resort in so central FL.
I spent a lot of time by the pool and noticed a family of a father, mother and two sons. The men were all much bigger than average cock wise, but the youngest boy (about 17) was monstrous!!
He was sort of retarded or mentally challenged if politically correct. He was always horse playing with younger kids (boys and girls around 13 years old). They seemed to be ok with him, but the young girls sometimes stared at his huge cock.
Other adults around the pool soon noticed him and I overheard some comments by them about his size!
Usually his mom or dad or older brother were by the pool, keeping an eye on him.
He stayed soft but his cock was 8 or 9 inches long and very fat. When I got back to by room I jacked off thinking about his huge cock!!
On the third or forth day of watching him and other people nude by the pool; his mother got up and told him to shower up as they were all going out to eat. She left him with some soap and shampoo.
He went under the very public open shower, soaped up and while washing his cock it began to grow and he seemed oblivious to his growing problem!!
By now everyone around the pool was watching his unconscious show!! His phallus grew to over 12 inches long and bigger around than my wrist!! He rinsed off and although his cock was engorged it still hung down and wasn't totally hard!!
He left and I was half hard by now and I noticed so were some of the other guys around the pool!!
I headed back to my room and jacked off twice; thinking about his MONSTER COCK!! This is a true story!!
