I only had a spotaneous ejaculation twice.

The first time was in high school. It was a hot fall day, and most of us were wearing shorts. Anyway, we had an assembly, and I was sitting next to a really hot guy who was also wearing shorts. During the assembly, our legs occasionally rubbed against each other. Well, I got so fucking turned on that I blew a humongous load in my briefs. To this day, I don't remember what the assembly was about.

The second time was with this really hot guy in a motel room. He was wearing a tank top and tight jeans; he had a great build. We were sitting on the bed fully clothed, and he began to rub up and down my left arm. I was so hard and horny that my dick began to pulse and throb and shot off what seemed like a never-ending load into my briefs. I apologized to him and told him to give me about 5 minutes and I'd be ready to cum again. We had a great time that night and saw each other several times after that memorable night.
