Thats what i do as well , but in my back garden . I hav flats that overlook so there are others that can see , which adds to the thrill . I am normally naked in my garden anyway in the evenings
When I'm alone, I do that late at night. I go outside completely naked, or in lingerie, lay in my driveway by the road and masturbate. I then give myself a hot golden shower. The excitement is great
