I and my half erect penis. End of the day. Last masturbation session, at work. I switch off the computer and get totally naked, facing the window. The door is unlocked, but I know there is hardly any chance of getting caught. I slowly tease my penis. Sometimes, I use some lube. 30 mn to an hour of pure masturbation. The sounds of the rings, as I stroke my penis in rythm with my grunts, as I mumble the word “masturbate” over and over in every declensions, make me feel as a complete masturbator - you know what I mean, you’ve been there too, haven’t you?
