I worked in a small company that had only 10 employees. The owner/president was a woman and I reported to her. It was around 8:00PM one night and I was working late. The office was dark except for my office where the lights were on. The owners office had 2 doors. One led to the reception area and exit, one to the area where I worked. Usually when I would leave I would go through her office because it was a shorter walk otherwise you had to walk around some cubicles and down a corridor before you got to the exit which was about 4 times the distance. I had to go to the washroom so I had to leave the office as the washrooms were just outside reception. I decide to walk through the owners office and was surprised to see the light on but shocked to see her there and even more shocked to find her the way she was. I guess she didn't expect anyone there and she was changing. I caught her bent over with her ass towards me. She wasn't wearing panties and I got a view of her ass and pussy from behind. She begins to straighten up and I see all she is wearing is a bra. She doesn't know I am there yet. She begins to unhook it and as she is turning around towards me starts to remove it exposing her breasts. She is basically naked and when she sees me panics and covers her breasts. She is frozen in shock as am I. I am staring at her but since her breasts are covered I am looking at her uncovered hairless pussy. She then panics again as she sees me looking down there and takes both hands and covers it leaving her breasts fully exposed. I finally realize I should probably leave and head back to my office. Within 10 seconds she shows up there too wearing an unbuttoned blouse which is covering her breasts and pussy. We had a talk about what just happened and how it would be best we not mention it to anyone. I apologized for walking in on her and she said it was her fault for changing in her office with the doors wide open. I think we both were still in shock but the more we talked the more calm and relaxed we both became. Towards the end of our talk she mentioned that I probably never expected to see her the way I did. I agreed that I never did. She said it was embarrassing to know I have seen her naked. Then unexpectedly without thinking the following comes out of my mouth. "Did you want me to get naked for you?" She told me I didn't have to but since I was offering, why not. I knew doing this wouldn't lead to anything as she was married. I began to remove my clothes one by one and watched her reactions. She was holding her unbuttoned blouse closed with her hands but as I undressed she didn't and I noticed her blouse fall open. I could see her pussy again and one breast. Once I was down to just my underwear she removed her blouse and told me to show her what I had. Off came my underwear and she was now looking at me naked. I was becoming hard very quickly with the way she was now sitting. She had her legs open and made mention I seemed to like seeing her pussy. I admitted I did and she told me I could come in for a closer look but not to touch as she reminded me she was married. She let me come in for a very close look and then said that this was the closest she had ever come to cheating on her husband. She mentioned she could feel my breath on her pussy and it was getting her wet. She told me to stand up and grabbed my hard cock. She had a look on her face like she was confused. She told me she would let me lick and finger her pussy if I wanted but I could go no further. She was in her early 40's, good looking, and I figured it could earn me some bonus points at work so I got to work between her legs with my tongue. It didn't take long for her reach a mini orgasm and her telling me so. She had another confused look on her face. She told me to change places with her. I was on my back now and she began sucking my cock. She made me promise to tell absolutely no one about what we were doing and then she was on top of me with my cock inside her. We were fucking and she was really into it as was I. We were finally done and she began to have some worries. We didn't use a condom and she was worried she might get pregnant. She told me it was useless worrying about it now but the next time we do this I better wear a condom. I didn't think there was going to be a next time but apparently there was. A few days later she walks into my office after hours and throws me something and tells me to put it on. It was a condom. She bent over, lifted her skirt to expose a pantyless ass and pussy, and told me to hurry. I got hard almost instantly but was having trouble with the condom. She told me to hurry and, seeing me having trouble with the condom, told me to forget the condom and to just fuck her. It is becoming a regular occurrence which I don't mind and I am finding when she gets turned on she can't even wait a few seconds and needs to fuck as soon as possible. She does this regularly now and found another form of birth control so condoms are no longer required. She has told me this needs to stop but it is always her coming in baring her pussy to me and expecting me to fuck it.
