I have had a dream of being in a downpour off and on for years, naked of course. The feelings of waterdrops beating down on me, soaking me completely would ensure I woke horny, at the least. At the most, I awoke with my cock rigid and erect.
However, it was always a dream, as living in the north, even summer rains were cool if not cold. Then I relocated to the Carolinas and realized that the summer rain was warm, and the downpours are heavy.
The initial experience was when my wife and I were driving up the driveway in the car and she remembered that she had left the pickup's driver's door window open. Instead of racing into the house, finding an umbrella, and then going to close the window, I took the direct approach.
I just got out of the car and ran to the truck and closed the window. In seconds, I was soaked to the skin and took my time walking back to the house. I entered porch and my wife met me with a towel. I stripped to the skin and dried myself off before entering the house.
The next thunderstorm was impressive with the fireworks lighting up the sky and the clouds opened a deluge. It was just after dark when I saw the in-ground pool was nearing the point of overflowing. It seem practical and I simply stepped out into the storm bare-assed naked.
Setting the system to pump out the waste water took but a minute, and in that time I was soaked. While the pump worked and the water level slowly fell, I was reveling in the feeling of the warm rain beating on my body.
The water dripped off my short hair and ran down my arms, my chest and back, and off my semi-hard cock. Standing there in the dark with the rain soaking me brought back all those dreams of being naked in the rain. If anything, the real thing was even better than the dreams.
I knew that no one would be out in the heavy downpour, but standing in the dim light I could imagine unseen eyes making out a naked man with his arms outstretched in pleasure and joy. While I expect that few would want to see such a sight, the exhibitionist in me imagined eyes that lingered on my naked form.
The sensations of the rain along with the exhibitionist thoughts that flowed through my mind combined to cause my cock to swell. I didn't become fully erect, just thickened and jutting straight out from my body. My cock bobbed and swung with every step, and it was with a bit of disappointment when the pool level was lowered and I had to turn off the pump.
