I've gotten into the habit of holding in my piss all day til nighttime. When my aunt is gone and it's nice and dark out I go out on the lawn and piss like a dog; it really gets me off marking my territory. Sometimes I even drown the flowers in her garden with fresh hot piss, something about marking all over other peoples' property gets me even more ramped up! I always have the best orgasms after I pee in the yard, like the good dog I am.
