I started this thread because I think it is odd to spew out info like the exact measurements of a family member's erection without any explanation about this would occur. I can't imagine being in a situation with my father and measuring our units. I think by starting with HOW you saw this, helps separate the fiction from non fiction

My brother I saw countless times. We shared a room and a bathroom until he moved out in our 20's. Morning wood was like a daily occurance.

The other family member I saw hard was my brother-in-law. I posted this elsewhere last year.

"My brotherin law is 42 and he took my brother 32 and me 25 on a fishing trip. We teased him about being old as we were waking up in the cabin, so he got out of bed, said look at this, and he pulled off his underwear and his hard-on bounced out. He said I'm 42 and I still get morning wood everyday! Who cares about getting older! Then he said our sister gets this everyday and we said too much information. It was hilarious."
