Like most boys eleven years old, I started getting erections at odd times and didn't know much about them. Back then, there wasn't a lot of information available and guys mentioned their "boners" as a matter in course. Also back then, many boys were starting to work out with weights and the like with hopes of bulking up for the football team. Because gyms were few and far between, most of us had our own weights, either in the garage or the basement.
One day, I was lying on my back doing fly presses and my customary boner was starting to throb. I lifted the waistband of my shorts and jock to see what was going on. I was startled to see my penis covered with slime. And it was throbbing more and more. I resumed my presses in hopes that the growing tightness in my groin would go away. Suddenly, I had this overwhelming feeling that I had to pee....Right Now! Jumping up, I ran to the bathroom and pulled my shorts and jock down under my balls. My penis immediately sprang up like a coiled spring, some more clear fluid ran out of its tip, then suddenly everything began to pulse. Without any touch from me, it jumped up an inch or so and white fluid erupted from the tip with enough force to splatter the wall above the toilet tank. The next contraction shot cum all over the toilet itself. The shear power and feelings took my breath away and I grabbed the towel bar for support. My body was not done yet. Pulse after pulse pumped out. I wanted it to stop, yet, at the same time, I wanted it to continue.
Finally, the last contraction forced a good dribble out and I collapsed to my knees, panting. I don't know how long I stayed there, but eventually, I got up and cleaned the walls, the toilet, and the floor.
