I've been reading about how giving a hand job is an art, and I believe that.
When I was in high school, my bud would give massages and super hand jobs to the athletes at our school and those in junior college. He would also take care of the loggers and truckers in the area where we lived who were hurting. He learned a lot about massage from his dad who was a Chiropractor. He did very well financially for a hobby.
Jim thought my dad was the greatest guy in the world and he was. Jim would take care of dad really well and give him an after-massage jack off worthy of the Gods.(When Jim gave dad a soap suds massage, and jack off, while dad was standing, his cum shot would be about five feet!)
Sometimes, I would be with dad and the ecstacy from his orgasms was astonishing. Jim jacked off dad for years, and dad jacked off Jim also. I was out of the picture. Rats!
