Thanks for letting me have my say.
My bud's dad, Art, is an avid hiker. One summer day I went hiking with him, partly because I wanted to and partly because Eric, my bud, was home with a bad cold.
When we got to the top of a small 'mountain', in my opinion a large hill, he surprised me by taking his cock out of his jeans and was jacking off. I asked him why and he said he likes to 'anoint' the places where he has been! I was 16 and my six and a half inch cock wasn't as big as Art's. I joined him and we mutually jacked off each other.
If that wasn't an explosive orgasm for me, I don't know what one is. Art had in my opinion, the perfectly formed cock and balls. eight inches by seven inches uncut and he had cum coming in waves out of his cock. He so sexed me up that we jacked off each other again after a rest of 30 min. or so. I didn't go hiking very much with Art, but we sure became regular mutual jack buds at home for three years until I joined the Navy.
