I just did this an hour ago.
So I'm 21 and home from college for a little while. I don't have my own room anymore, so I have to sleep in the living room. Not really the best place to get off if you know what I mean.
So tonight its raining, hard. And it just so happens that everyone except me and my step-father are gone. So I decided to go out back to enjoy the freshness of the rain soaked air. I go out their and there is a little roof over three small steps. I'm standing on the top step with my back against the door, just enjoying the rain. I had to adjust my dick inside my pants and as soon as I did I got the urge to feel it. I'm eight inches long and three inches wide and uncut. So I reach inside my pants and just rub my dick and it felt so good that I decided to just jerk off right there. Now we live in a two family house and the people downstairs have their own back porch as well, my step-father is upstairs awake, and across the yard there are lights on in the house beside us. So there is a risk of getting caught, but it just made it better.
I pull the shorts I have on under my jeans down and unzip my jeans and let my dick hit the cool night air and it was amazing. I slowly wrapped my hand around it and started pumping, twisting my hand when I get to my head and coming back down. I expose the head of my dick and massage it for a minute. I also love having my ass against something cold, it's weird but it just makes it better. I remember walking with a coat on and my ass being exposed to the cold leather and loving it. Anyway, I pull the back of my pants down a little and put my ass against the door. Mission completed, it was a great feeling. The wind was blowing hard, so my dick and the rest of my body was getting hit with the cold rain and it made it all the better. All the while I'm looking around to see if anyone is coming or can see. I get a little nervous and pick up the pace. Five minutes later I feel my nuts getting ready to explode so I turn to the side of the steps and prepare myself. I can't hold it any longer and I let it out and it shoots far, past the steps out in the rain, a few feet. And I'm spent. I pull up my pants and start to open the door. As I do, I see my downstairs neighbors light come on, so I rushed inside and closed the door. She came out to take out the garbage and when she walks out I can't help but smile because if she was only a minute earlier she would have gotten a show. Enjoy!
