This happened with my ex, we split up earlier this year but have erm.. well met up a couple of times since when we have had the 'need'. We are getting on quite well as friends. He is 22 and gay and I am 19 and bi.
After we sorted out our needs together and been to the pub a couple of weeks ago he drove me home. When we got near to my house we began to poke one another on the leg and say 'poke'. This is something that we have done for a long time. He went for my cock so I suggested that we go somewhere quiet to have car fun-something we have always said we would like to do (we seem to be doing more of these things since breaking up). We drove into a realy quiet out of the way car park and turned off. We started to kiss and feel one another through our jeans. We then took our cocks out and started to masturbate, we also masturbated one another. We then discussed where we would cum. After thinking about it he took off his sock and then continued to masturbate until he got close and put the sock on his cock to catch the cum. He then handed me the sock and I put it on and masturbated until I came, feeling his cum already in inside, which turned me on. He told me to throw the sock out the window and it landed in some bushes.
He then drove me home.
It was a good experience, and I can now say that I have had a sexual experience in a car.
Although we are now only friends we both enjoy dealing with one anothers needs, we both seem to be horny at about the same time as one another.
