My best naked door encounter so far

Maybe 8 years ago it was spring time warm so I had the doors and windows open. Nobody home, and I was naked. I had a big chrome cock ring on and was playing around the house. The front door was open, I have a screen, when I came out of the kitchen with a stiff dick. There at the door was our female mail carrier with a letter that had to be signed for. She had already seen me, so I just went to the door and opened the screen. She gave me the letter, and I signed her receipt. She never said a word about me being naked, or my boner. It just made it a little more stiff, I think. I was hoping for a good reaction, but at least she didn't freak out about it. That was very hot.
