I used to streak when I was younger. I would be up later than the rest of the family, strip naked leave the door on the latch and run around the block. For some reason I always took a pair of boxer shorts with me (as if that made a difference if I was spotted) as security. But one time I remember going without them, daring to run naked, sometimes with an erect cock, wondering if anybody spotted me.
When I got home it just took a few strokes before I came. What a rush!
