I normaly wear dockers to work , on this particular day I had to dress up for something. I went out and bought a nice pair ofdress slacks to wear for the occasion. When I got dressed that morning I noticed that my boxers were very visible so I decided to go with out. This was very different from going commando with shorts or jeans as I soon found out. Every time i would move the cool air and smooth frabric would rub. This just felt good at first, but soon was getting turned on by the feeling and was also getting aroused. About 4 hours into my day I noticed I was staying semi erect because of the rubbing I also started to feel pre-cum on the inside of my thigh. This continued all day and by the time I was home I had pre-cum all down my right leg.
