Reading theses stories brings back many recollections. This one involves the nick name Tripod given to me by my circle jerk companions when I was 15 and my penis had Grown to its final size which was 7 inches.
I matured earlier than the two other boys in our circle jerk although we were all the same age. I had a 7 inch penis by then. Once a week we had a circle jerk in our tree house where, among other things, we stored a tape measure and vaseline. The tape measure was used to keep a record of our growing penes. I had a 5 inch hard until during one of my many solo jerks when I was concentrating heavily on my fantasies and the pleasure in my penis, it seemed to flex its muscles, and suddenly get longer and harder. I jerked ever more vigorously when this happened, and soon shot a tremendous load. Before this happy event, my penis was 5 inches long.
At our next circle jerk, when we were preparing our penes by lubing up, one of my friends noticed that my penis was larger, saying, 'Look at Tripod his peter got bigger.' They both wanted to know what I did to make it grow; they were envious as well. The conversation went like this:
What did you do to your peter?
I don't know, I was only jacking off and it suddenly got bigger.
Let's measure it after we come.
When we all came, we got out the tape measure, and found that I now had a 7 inch penis.
