Again, I wish I had pic of this one (before digital cameras). In the army, I would often go from the shower naked to the urinal, in full view if someone opened the door. One time I felt lucky and started jacking and hoping no one would enter. It didn't take long until I squirted cum in the urinal, standing there totally naked. This led to many more urinal cums. Going to have to cum in a urinal again soon.
