I love when people I don’t know see me naked, especially when the mail comes. My mail deliverer is a woman, probably in her thirties, with a decent body. I decided to show her my naked body. I started to masturbate a little. Then I wrapped a towel around my lower body. When she arrived, I walked out to greet her and to get the mail. I gave my towel the necessary nudge for it to fall down, exposing my erection and naked body right as she was approaching the steps. I saw her glance down and then back up at me and said, "Someone’s exited to get the mail." I laughed. As she turned to walk away, she gave my genitals another glance and winked. That was fun. -Billy, 19
