When I was walking the dog this morning, I let my mind wander to thoughts of masturbation, to pass the time while the dog endlessly sniffed and-resniffed every tree and hydrant for traces of other males marking their territory. Normally, I guess, people fantasize about sex when they masturbate, but here I was fantasizing about the act of jacking off itself. I just wanted to be home, shut up in my tiny little office where I've got my computer, to look at porn, and to feel my penis getting erect inside my pants, feel it straining hard against the fly, until finally I had to unzip and ease my throbbing boner out. And then would come the ritual of stripping down... losing pants, then shirt, then finally underwear and socks, so that I could be totally naked as I worked on my stiff dick, my left hand cupping my nuts and then moving up to stroke the hair on my chest and play with my nipples, making them hard, as all the while my right hand slid up and down my erect penis shaft... Anyway, I was thinking about all of this while walking the dog, and enjoying the fact that under my coat and pants, I had a major erection going, and I was feeding my hard-on with all these thoughts right out in public, and anyone who saw me would've just seen a guy walking his dog before going in to work.
