My First Time happened shortly after my twelth birthday. I had never really masturbated before, I had just done some you show me yours and I'll show you mine stuff.
Anyway, it was summertime and I had got a rash on my feet from wearing sweaty sneakers. I was taking a shower and was fooling around with the water by putting a washcloth over the showerhead; holding it with one hand so it would make a stream of hot water which felt good when I let it fall on my itchy feet.
I don't know why, but I ran the stream on my cock. I was immediately rewarded with a tingling rush like I had never felt before! I kept it up and after a few moments, an incredible spasm overtook me and several long streams of crystal clear gooey liquid shot out of my cock, doubling me over in the process.
Of course, it became the focus of my free time after that. After a few more shots, there were white streaks in my loads; eventually becoming all white. I worked out several techniques, wet and dry, but running a stream of really warm water on my dick while pulling the skin tight and leaning against the shower wall (to keep from falling over) was my favorite.
