My Boss

I work for a small company that only has 15 employees. I report to the president, who is also the owner, and she is 52 years old. Most people leave by 5:00pm but one day I stayed late and was there after that time. It was about 6:30pm when I went to go to reception area to do some photocopying. The layout of the office was such that I had to go down this one hallway do a sort of U-turn and comeback down another hallway to get there. My bosses office had 2 doors going into it with one on the side where my office was and the other where the reception area was so it was a quick shortcut from my office to where I wanted to go. I decided to use the shortcut and started to walk through the bosses office when I see her standing there.
It was unexpected and even more unexpected when I see her in just a blouse and what looked like leggings. She didn't seem to be upset that I caught her that way and asked what I was doing there after hours. I told her that I was catching up on some work and was just going over to do some photocopying. She then jokes that I probably just wanted to take a peek at her in her underwear. I looked closer at what she was wearing and noticed they were pantyhose and they were very sheer and she was wearing no panties underneath them. She told me to go do my photocopying and I could cut through her office on the way back.
I did my photocopying and cut through her office on my way back. She stopped me and asked if I was going to be a gentleman and let her see me in my underwear. I didn't know if I should but she pushed the issue and made it clear that we would not tell anyone about seeing each other in our underwear. I pulled my pants down and she wanted them right off, so off they went along with my shoes since I had to take them off to get my pants off. My shirt was hanging down covering my underwear so she wanted it off and told me to take my socks off too. I was getting aroused by what was going on and took my shirt and socks off leaving me in only my underwear.
I am standing there facing her as she is looking me in just my underwear. She tells me she wants me to turn around and give her a real good look at my ass. She goes on to say that she noticed long ago that I have a great ass and wants me to show it to her. I thought this may be taking things too far but with how aroused I was feeling and her really wanting to see it I turned around and I heard a "mmmmm" sound from her. I pulled the back of my underwear down exposing my bare ass to her. I heard a "WOW, I didn't expect that". I told her that's what she requested. She told me she just wanted to see my ass in my underwear but wasn't complaining about me baring it. I let her look for a bit before I pulled them up and turned facing her.
She said she got the best of this whole deal as she saw my bare ass , can see the outline of my cock in my underwear and goes on to say all I saw was her in her blouse and pantyhose which covered all of her. I told her she wasn't 100% correct and went on to say that her blouse fully covered her from the waist up but her pantyhose were very sheer. She didn't believe me about the sheer pantyhose so I mentioned I liked the way she was fully shaved except for the little "V" shaped hair she left right at the top of her pussy. Her expression changed and she quickly ran over to a mirror in the office and noticed for herself that I wasn't lying. She said she was embarrassed and truly didn't know how much she was showing and says at "least you haven't seen my breasts". I then asked if this meant her pantyhose were coming off now. She told me I was funny and then, pointing at my underwear, said those would have to come off first. I now she wasn't serious but thought it would be funny, and also a surprise to her if I did, so I actually did it and took them off. There was another "WOW" and a " I guess its my turn now" and then she did it and took her pantyhose off. I decided to go to her and started unbuttoning her blouse. She didn't stop me and after I removed her blouse she unhooked and removed her bra. We were both naked and she led me to a couch in her office where she lay down on and spread her legs. It was quite clear what was coming next and we made out on her couch.
The next day at work she calls me into her office and brings up what happened the night before. She then tells me she wants an after hours meeting with me tonight to which I agree. Everyone had left and she was very aggressive with me. I walked into her office and she stripped me naked and went right to work on me. All she did was give me a blowjob and nothing else. Following meetings were quite different. They were always after hours but the sexual acts no longer occurred. She began to call me at my office desk and told me to strip there and come over to her office naked. I did as she asked and basically just looked me over. She told me we shouldn't have had sex and no longer will but she still likes seeing me naked. I then get told I better be OK with this otherwise my employment may change and she didn't elaborate how. I am an exhibitionist so I didn't mind but there still was the occasional sex act she had me do as she watched.
