Answering The Door Naked

Thought I would tell about what I did a couple days ago. I was at home on my day off from work, and like most times when I'm just relaxing, I was naked on the couch watching TV. I was kind of drifting in and out of a nap when someone knocked at the door. I got up and looked out the peephole and there was a kid standing there, probably about 18 or 19, dressed in a button-down white shirt and tie with a clipboard in his hand. I asked who it was, and he said it was a political survey; I would assume it was to make some extra money while in college. I told him to hang on a second, and I was about to go grab a pair of shorts to put on, but then I thought this would be a perfect chance to show off, since I love being seen naked by strangers. I opened the door about halfway, standing in front of him completely naked. He took a sharp breath and started stammering. "Um...di-did I catch y-you at a bad time?" "No, it's OK. About how long will this take?" "Um...maybe...10 minutes?" "OK, sure, go ahead." He started asking me the questions as best as he could, and I took my time answering them. Even though I started out completely soft, after a couple minutes of exposing myself I started to get hard, and before too long I was standing there in front of this random kid with a rock hard erection. More than one time, I caught him glancing over at my hard cock, which was getting me more and more in the mood to masturbate. By the time he got to the last few questions, a big drop of precum was hanging down from the slit, swaying as my cock bounced and throbbed. After the questions were over, he had to ask the personal ones; name (I asked to remain anonymous, for obvious reasons) date of birth, race, those kinds of things. While he asked these I was leaning against the door frame, and I took hold of my cock and slowly started stroking it. When I squeezed it I could feel a huge drop flow out, and when it fell I felt it drop onto my foot. I was so ready by that point, he was about to see me cum whether either of us liked it or not. He finally said it was complete, thanked me for my time and hurried off. As soon as I shut the door I leaned against it with one hand and started stroking hard, and almost instantly I shot a huge, thick load all over the door and the tile. I stood there for a few seconds catching my breath, then grabbed a towel to clean up my mess. When I got back to the couch I was still hard, so I started stroking again, thinking about what I did and imaging him telling his friends later on that a guy was practically jerking off in front of him. I stroked harder, moaning with my ass raised off the couch. I finally came again, an equally large cumshot streaking across my chest. I relaxed back down, licking what was on my hand and slowly spreading and wiggling my toes. Without even trying I fell asleep, and about an hour later I woke up and masturbated again, still covered in dry cum.
