Nothing too dramatic or amazing here, just a fond remembrance of the first time I came. I was twelve, already sexually awakened, but ignorant of the physical processes involved. I had seen one of the 'wilder' neighborhood boys masturbate himself to ejaculation, not thinking much of it, as if it was his own peculiarity, what white stuff oozed out of his dick when he played with it. One evening, I needed to pee, so I hid by bike in a patch of woods near my house, and relieved myself. I had no particular sexual fantasy in mind, but for some reason, I was reluctant to put it away, and started playing. Got one of those wonderful 12-year-old's erections, the kind that stay hard by themselves for 15 minutes without being touched. Still, I wasn't really thinking of anything special, just reluctant to stop playing. Every time I stopped, my hand would return to my cock for another fondle. Soon, the intervals shortened to nonexistence, and I was stroking & playing constantly, reluctant to let the cool feeling subside. I had no idea what an orgasm was. Never had a nocturnal emission or anything. I became alarmed at a weird, tingling, 'electric' feeling in my cock, and finally stopped playing. Too late! I watched in amazement as I shot a solid stream of semen four feet in the air! (no lie!) And about 5-6 more, each a little shorter. Shocked at the weird phenomenon, my head swam.
I vowed not to do it again, which resolution lasted about 10 hours. I tried again the next day, as if to find out if it would happen again. Oddly, it took at least three more times for me to calm down enough to anticipate and enjoy orgasms, and to connect that anticipation with arousal. It became sort of my hobby for the summer, and I visited that spot up to five times a day to shoot.
