I work standing at a desk. There's an old handle on the drawer and if I lean forward a little it presses into my balls just at the base of my dick. I remember every cute guy I have to serve and press harder as I say 'Thank you sir.'
By the time I go for my break I'm rock hard and leaking precum. I go down to the staff room. It's always empty, no one goes down there. I sit in the corner and put my headphones on. I can't see the door and I can't hear anyone coming down. The danger makes me start precumming like crazy. If anyone came downstairs they'd see and catch me before I had any idea.
I undo my trousers, and slide them down to my ankles. My shorts stained from precum and tented by my eight incher. I unbutton my shirt, but leave my tie on. I take my dick out through my boxer fly and coat the precum around my head, just slowly rubbing it in. I set my mp3 player so it stops playing a minute before my break ends. By the end of the break I am ready to burst, my dick-head turning purple. As soon as the music stops I start jacking madly, I cum almost straight away, bucket loads, and let it land on the floor and down the inside of my pants. I pull up my pants and feel my cum running down my leg. It doesn't show through my bad work uniform trousers. I catch my breath and go back upstairs and back to work.
