Note: This story was dynamically reformatted for online reading convenience. OK. I was in the wrong. I was married with 3 girls. 15, 13 and 9. This woman, I am going to call her "the woman" in case she reads this at some future time! She was 13 years younger than me. She used to wear silly hats and daft dresses when she came to the office, but there was something naive and sexy about her. Often she would sit next to me at the conference table. I could see her stocking tops and suspenders, she wasn't even wearing particularly sort skirts at that time. We needed to go on a business trip to America. I didn't choose her because of her stockings and suspenders - she was just the right system designer to visit the IBM sites with me and the other 7 or 8 guys. She was just very smart, exceptionally smart. She had transformed our major deliverable, our System Design, this was our blueprint for future technical infrastructure. She did it just because it was obvious to her that it needed to be improved. When I first took over the department she worked for a guy, that worked for a guy that worked for me. That was so wrong; she was better and smarter than both her line manager and his line manager (and probably me). I promoted her. Within 6 months she was a direct report. No sex involved, honestly. She was full of ideas. There was an American in our team too. Her husband was in the IBM team working with us. She was also lovely and clearly committed to her career. When they teamed up the woman and the American became a force for change that I couldn't, and didn't, ignore. Their efforts really moved the department forward. I actually went away to Scotland with the American's husband to see golf tournament at Troon. Such a lovely guy. The American and the Woman though were a formidable part of the team that both challenged and supported the ideas I had with the design of the infrastructure of the company we all worked for. In fact they challenged every idea I ever had and they were mostly right, or very nearly! We had an annual visit to IBM in the USA. As the senior manager I led the trip. The Woman and I travelled together in business class and talked the whole 7 hours to Raleigh NC. She told me about her early life living abroad and some of the nasty things that had happened to her during that time. She talked about her family and her husband of nearly 7 years. They were really happy together with their social life revolving around their local pub. She told me, not him, that his best friend tried it on with her but she rebutted his advances. She did let out a little gasp when I told her that I chose and bought all of my wife's underwear and most of her clothes. She had never experienced anyone being interested in her like that. She used to go the local market and buy 6 pairs of cotton knickers for £1. I know, she later showed me as she was taking them off! We spent a couple of days in Research Triangle Park, then on to Chicago via Poughkeepsie and Rochester NY before landing in San Francisco on Friday night. We had experienced an intense 5 days of business presentations and did some serious evening drinking on the way. It was always "in the lobby by 8" to get to the airport or to another venue - no matter how late we had gone to bed. Tiring but exhilarating. Saturday night in San Francisco we had all arranged to go to a dance club. I thought I heard the name correctly and the Woman and I shared a taxi. While in the taxi I gingerly touched her hand and within a few minutes we were kissing in the back of the car. When we arrived at the club we couldn't find any of our colleagues and it turned out that it was an alcohol free zone! We left about 2am and returned to the hotel. We were on different floors but I took her to her room before returning to mine. I stood in the doorway thinking "what am I doing?". I was thinking about going back to her room and knocking on the door, presenting my married self for some adultery! That's exactly what I did. She opened the door naked (maybe expecting me?) and before long I was naked too. I hadn't had sex with anyone but my wife for 20 years, but lust took over and we fucked all night. We had the weekend free in San Francisco and spent the time in record shops or her bed or in a bar or restaurant with our colleagues, who mostly hadn't worked out that we were sleeping together. We were due to fly back from NYC the next weekend. The week was a mad dash around offices in San Jose, Austin and Dallas. We spent every night fucking until the wee hours but were always up and ready in reception at the appointed hour. In NYC we were invited, just the two of us, to dinner with the IBM lead. He had been recommended a restaurant just north of Times Square. We all went together. The Woman had a maxi skirt on when I went to her room to take her downstairs to meet our host for the appointment. I gave her a passionate kiss as I lifted the hem of her skirt to her waist and pulled her knickers down. I gently stroked her mound as I kicked the cotton knickers away and dropped the skirt. That was the last time she wore knickers. At the dinner table I stroked her vagina with my toe! We fucked like rabbits when we got back to her room about midnight. We had to be checked out by 7:30 for the day time flight back to LHR. We managed to get adjacent seats again and on the flight home she wore the maxi skirt again and I made a point of getting my fingers inside her vagina. God she was hot! She was surprised to find her sister, her sister's boyfriend and the woman's husband waiting to meet her at LHR. I've always wondered what the husband made of his wife coming home from a 3 week business trip with no knickers. I must ask her one day! SAN FRANCISCO
