Almost caught in the act

The problem with writing out your fantasies is that in the process you become a little horny. Normally this isn't a problem at home however when you are at WORK it can be slightly challenging. Case in point, I have been teasing my coworker all day by grabbing his cock and rubbing it through his pants as well as sucking on him for short periods of time. It doesn't take much of this and he is nearly ready to explode. Before too long he is shooting his warm load into my mouth and like a greedy little whore that I am, I swallow it all down. All is good right? Wrong. I need release now and unfortunately I need more stimulation then a blow job can offer. So the story goes... I find a quiet little place with a lock on the door and computer access and go to it. I love to stroke my Cock and I am not afraid to admit it, I think it is sexy when anybody masturbates, be it man or woman. So I am going at it looking as some porn online and I get just about to the point of no return when I hear keys jingling in the lock. FUCK ME! Now it goes without saying that it would be slightly awkward to be caught but worse if the person catching happens to be my boss. Sure enough Murphy's law pulls through and in he walks. I had my cock back in my pants and had been able to minimize the porn before he walked in but now I need to convince him that all is well. Normally the room is used for special tasks and remains vacant most of the time however I all ways plan ahead and have an "escape route" planned just in case. It happens that I knew of a special project that needed completion before the first of the year and access all the files necessary and had dummy paperwork laid out just in case. He comes in and looks at me and with a surprised look on his face and says " this is exactly why you performance appraisals are always excellent, you are always one step ahead of me and I am supposed to be your boss". I chuckled with almost a sigh of relief mixed in and just smiled as he closed the door and went about his business. Now that was close, but on the upside my boss thinks I am Johnny on the spot. Downside....no cum and all the hornyness is scared right out of me. Oh well, better luck next time.
