Seems as if we had been friends forever. She had worked for me for about eight years, and we had become intimate a few years ago. While we never had intercourse, we played numerous masturbation games. I have always been turned on being watched as I masturbate. There is just something about it that is so exciting. She was mainly a voyeur, but on occasion would play with herself as she watched.
By mutual consent, we felt that we were going too far with our activities, and stopped about three years ago. Sometimes we would discuss the past, but we would somehow keep our desires in check.
About two weeks ago, it became a different matter. We had been talking about masturbation, sex in general, and cum. We had even taken a break in our workday to look at some porn on the internet. We were both very turned on, but she went back to her office, and me to mine.
I just had to get off. A little while later, one of our clients called and told my friend that she had to come by our office and drop off some work. She said that she would be here in a few minutes.
My good friend, knowing that I would love to watch this girl come up the sidewalk, advised me that this would be an 'opportunity' to get off. Wow, I could not wait. I closed my blinds partway. Just enough to watch, but not be seen.
I closed my office door and took off all my clothes. I started to play with my cock as I waited. I wanted to cum right about the time she arrived. I knew she would be wearing a tight skirt and blouse.
Then I had a very nasty thought. It would be so exciting if my good friend came into my office and caught me looking out the window, jacking off. She agreed! She would receive the package from her, and bring it into my office.
I can not tell you how exciting this was. Me naked, standing by my window, with my cock in my hand. My office door opening, and getting caught by my good friend as I jack my cock. Of course, she watched until I finished.
Perhaps this would make a great porn movie.
