I assert my dominance by whipping out my massive cock. When I go to a public restroom that has a person at a urinal, I go right next to them. No matter the age of the person, I stand back  fairly far, about one and a half feet, just to make sure they can see my cock with their peripheral vision. They almost always finish immediately. One time there was a little kid at a urinal and I go to pee right next to him. I back step and unbuckle my belt. The kid looks over as I unzip my zipper. As I pull out my 9 inch cock, his jaw drops in amazement. I swear I saw him cum into the urinal as I started pissing. He finished up, went to wash his hands as I saw that his pants were covered in shit and cum. I felt proud of myself that day.
