Ah yes, I've jerked off at my last couple of jobs.
Right now it's almost a daily thing in one of the bathrooms, but if I'm busy then the wank breaks do not happen very often.
I used to have a private office when they transferred my two partners, for over a year! This office was in a very busy part of the building, but I could shut the door whenever I wanted, so...you get the idea! I would usually just sit in my desk chair, unzip, and go to town with some computer porn in my email. Other times I would be a bit more daring and lay down on one of the vacant desks and jerk off hardcore.
One time I got completely naked and laid on the tile floor and jerked off.
So yeah, um, you could say I enjoy wanking at work.
