The excuse is that I'm going fishing when I drive up alone to our weekend cabin on the lake. I do fish but the real reason is that I love to go naked which I am all the time I'm there. I strip off as soon as I arrive and stay completely naked until I leave. There's just no better aphrodisiac than being nude outdoors. There's no internet connection up there so no porn though I do have a small stash that I don't need. Its enough to be naked and to use my imagination to indulge in hours of great masturbation. And I mean great. I've had some of the best orgasms of my life masturbating on the lake's small beach or wandering through the woods far enough from the cabin to have no quick retreat if someone comes. Visitors are rare though a park ranger came one day. I opened the door to his knock without thinking. He took in my nudity with a surprised look (luckily, I didn't have a hard on) and said he needed to check my permits. I invited him in and felt his eyes riveted on my nude body while I rummaged for them. My nudism has always been private and I'm no kind of flasher but I kinda liked him seeing me. I decided not to put on a robe. He told me his name was Steve and said in a very officer-like way (he addressed me as sir) that my nudity was technically against the law. Anyone could come by and see me, people with kids who might be offended. I'm inside and my robe is within reach, I said. It wasn't when I knocked, he objected. His stern manner made me feel uncomfortable and I covered my cock with my hand. To my horror, instead of securing my modesty, the contact made it grow and there was nothing I could do to stop or disguise it. I've never thought of myself as having gay leanings but being nude in front of Steve in his smart blue uniform and with his official manner was having an uncontrollable effect on me. I half expected him to pull out the forms to book me for gross indecency and I had visions of being taken to court and everyone finding out. Instead he stepped forward and removed my hand from my genitals. I now had a full hard on. You see what I mean, sir, he said. Women or little kids come by and see this sort of thing, they're going to be shocked and frightened. His hand reached out for my cock, squeezing it hard, almost painfully, against his palm with his fingers. I held my breathe, not daring to speak. Slowly at first, he began to masturbate me and then faster but it still felt like a satisfyingly long time before he let me cum. We both stood stock still and speechless facing each other for a few seconds until there was a burst of chatter from his car radio. I need to get that he muttered. What about the permits? I said. He looked back at me standing there naked with a string of cum still dribbling from my cock. I'll be back this evening, he said and was gone.
