I've pissed next to most male family members and my uncle has the loudest piss stream. It's like a jet coming out. It splashes and depending how close the urinals are, my arm has gotten splashback a few times.
Of course. Did with my father all the time. It was my grandfather that made my jaw drop everytime though. He would reach in and pull out an elephant trunk I was always astounded.
Had a pervy uncle who would always say lets see how big it is now and joke around.
me and my cousin use to sleep over at each other‘s houses one day I went to his house and we went under the blanket with each other and jerked off while watching porn
