i have a 2 stories, kind of unfortunatly. one of the largest i have seen would have to be my grandpa. ya i know, kind of gross, he is kind of young so hes not all wrinkly thankfully, but we were at a pool and we were getting out of the pool and his suit hung to his body and u could see the outline of his penis like halfway down his leg.
and once again my second ivolves another family member. this time my uncle, who is my grandpas son so probably gets his genetics. he took me fishing on his boat on an overnight trip. he show a huge bulge so i have known he was big for a while. i woke up early in the morning and was walking around and saw my uncle outside totally naked facing me, his penis was 7 and a half inches flaccid. he saw me and said sorry and put his underwear on. still showing a huge bulge. he asked if i wanted to talk about it and i did and he ended up giving me andvise about my rather large member
