Outdoor Erections

I go outside early every morning with just my gown on and nothing underneath. The house next door to mine is unoccupied and there is no fence between us. There is only one other house in the area, which is next to them and is also unoccupied. I like to take my gown off and walk into my neighbours yard naked with a big erection and then masturbate in the open and cum onto the back wall of the house. I could be seen by any cars driving past so that makes it extra erotic. I haven't been caught yet.
