I'd been masturbating, having dry orgasms. I began ejaculating, but my hardon was still pencil thin and about four inches long. My penis suddenly got bigger one day when it was getting attention in the bathroom.
I'd been getting hardons, but wasn't wise enough to produce orgasms in that I didn't stroke long enough. With the help of a cousin, I'd become a very efficient dry orgasm machine, and eventually the orgasms were full blast white cum ejaculations.
I'd grown a respectable bush, but my erection was still a boyish four inches. This would change dramatically. It happend one day when I was home alone sitting naked on the toilet well lubed with vaseline. I was pounding away joyfully when I felt something deep inside the shaft suddenly give way and my hardon swelled to about five inches. It was a wonderful surprise. I'd like to hear if anyone else had this experience.
