Slow Week at Work

Most of them have been nothing special but on Friday it was a bit different.
The other times I have done it this week have just been the usual old go to the toilet and sort myself out but on Friday I had to go to our off-site filing place which was in a big building where there was never anybody there.
So I grabbed my coat off the back of my chair and got in my car. Whilst driving I couldn't help but rub my crotch through my trousers I was just so horny. When I got there I could feel that my pussy was soaked. I knew something would have to be done.
I climbed the two flights of stairs to the floor our room was on. I unlocked the door and turned the light on to see the massive stacks of boxes that went around the whole room. I closed and locked the door behind me, now I could do anything I wanted without being interrupted. So I sat down on the step ladder that was there to reach the top shelves I took my coat off and threw it to the floor.
I started to rub my pussy through my trousers again and reached a hand under my top to rub my breast, I was very horny my nipple's were very hard so I started to pinch and twist them. I took my top off and put it with my coat, I now had my hand in my trousers and was rubbing my clit on the outside of my panties which were soaked with my juices. I took my bra and panties off next and it was very exciting knowing that I was naked somewhere that wasn't my house.
My pussy was dripping wet I started to rub my wet clit while I was playing with my nipple's. After a while I wanted something inside of me so I took my hand from my breasts and put a finger deep in my pussy and started to fuck myself with my finger while still rubbing my clit.
I was very close to cumming I had two fingers deep in my pussy fucking myself hard I also slipped a finger into my ass. I was moaning loudly because there was nobody about my pussy was pulsing, I was breathing hard until I exploded all over my hand. My hand was covered in my juices, I just had to taste some so I licked my fingers clean. I finished the filing, I locked the door and drove back to work. My boss asked what took me so long. I lied and said that there was traffic on the way.
I'm now very horny again after writing this story I will have to do something about it.
