You won't believe this, but it is absolutely true. I did this for about 16 years.
I worked in the office at a factory. I arrived every day at 6:15 am to start work at 7am. There was a lady that i was having an affair with that worked in the same building. This was a large facility and this office building had several hundred employees in it. She would arrive early too. She ALWAYS wore a dress with stockings and heels and never any panties. This was in the 80's and 90's when most office women wore dresses. Everyday she would come by my office on her way to her office and pull her skirt up, get up on my desk, spread her legs and I would fuck her. I just unzipped my pants so i could quickly recover if someone walked in. This was every day.
Sometimes during the day she would come by my office and sit in the guest chair. These were cubicles so the top of the walls were just below eye level. Very easy for someone to walk up and look over the wall into my office. She would pull up her dress or skirt and finger herself and play with her clit. She had a large clit and would brush her fingers over it to make her cum. I would stand up to watch for others walking by and she would do her thing. She never could cum without closing her eyes. One day when she came by, we decided to fuck, so she pulled up her dress, sat on the table, spread her legs and I slid my dick into her pussy. We had just started fucking and my desk phone rang. I never stopped fucking her. I answered the call and carried on the conversation without ever stopping fucking. She got a kick out of that.
She drove a full size van at the time and it had a bed behind the second row of seats. We would go out in the parking lot and get in it and fuck often. There was so much factory noise and the windows were tinted so no one could tell we were in there. We would be hooked up nuts deep and someone would walk by within 2 feet of us and never know we were in there.
She was submissive and loved to pleasure a man. She loved to suck my dick and lick my balls. One time her husband was away on a trip and she was for sure he would not be back for a few days. She took me to her house in that van and drove into the garage and shut the door. She took me into the house and wanted me to fuck her in her husbands recliner, on the floor in front of the TV, on the table where he ate his meals and in their bed. This I did and she loved every minute. This woman loved to fuck.
