Since my Doctor and I were talking about cancer of the prostate, it was recommended that oldsters masturbate about three times a week, if they have no partner, for prostaste health. Egads! that's more than when I was young.
Anyhow, about five or six of us get together once a week to jack off together. It's great. Every so often several younger men joins us and there is a flood of cum from us. Some of the guys are in their late 70's and early 80's and they have super hard cocks and can shoot a load.
We would jack off each other just for a change, and we all agree it is better if we have another guy jack us off. Our orgasms are out of this world!
