I remember I was 9 or 10 and I was home with my family. I was in our living room and I had noticed a vibrator lying next to the couch. Wanting to just play around, I turned it on and was enjoying the silent but powerful sensations. I started moving it around my body, arms,legs,etc. I then moved it near my crotch area. In the beginning, there was nothing but a tingling feeling. Up to that point, I had never really noticed getting a hard-on before nor had I an orgasm, but the vibrator felt so good I moved it around concentrating on my crotch. I was doing this literally for 15 minutes as this pleasurable feeling sustained itself for this whole time. Again, I had never experienced an orgasm before and didn't really know, that what I was doing was masturbating. I finally stopped the machine after I noticed the shorts I was wearing were wet. Embarrassed, I quickly went to the bathroom to clean up as I was really soaking wet all around my crotch. I remembered I wanted to pee, but I tried very hard and couldn't.
I later realized what had happened; I was cumming and cumming for about 15 minutes straight. Since 'I had fresh pipes' if you will, the cum just flowed and flowed and it felt like a volcano oozing out. Till this day, that was the most satisfying ejaculation I have ever had. Imagine being at the cusp of pleasure, right at orgasm and keeping that feeling for 15 minutes.....I've had many more (using a vibrator....with my cousin) but I'll share later.
