Pleasant Surprise
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.
