I was hitchhiking one after noon after school when a Marine picked me up in his pickup. He was telling me about how great the Marine corp is and I should join up.
We then talked about sex and if I jack off. I said sure do and he asked me to join him in a mutual jack off. He stopped by the side of the road and we felt up each other's cock and balls and jacked off each other.
A first time for me. We jacked off each other 2 times before my stop. I was sold on mutual jackin'.
He had a beautiful 8 x 7 uncut cock and I was 6 x 5. I asked him if it was common for other Marines to jack off each other and he said we sure do. So it's the Marine Corp for me!
