Business meeting

We were sitting in my office, a man from a welding shop and I discussing a complicated weldment his customer wanted to build. We had the drawing open on my desk top computer and when he finished pointing out some features on the screen he sat down on the corner of my desk. I'm still sitting in my chair and have to look up to see his face/talk to him.
He kept pulling at his dick like it needed to be scratched or freed from it dungeon or something. I advised him if he need to do so to 'well take it out and scratch or adjust or whatever you need to do to it ,,,, the words just sort of flew out of my mouth. He just grinned and went back to discussing the project. A couple more tugs on his dick and it appeared to be growing. Maybe it was me staring at it, maybe not, but it was getting hard. I again suggested he just unzip, reach in and make the proper adjustments. Again he declined, so again the words just flew out when I said, "Here let me adjust it for you then" and reached for his zipper. He made no effort to stop me so I was sort of committed. I unzipped his pants and fished out his dick, and ask does that feel better. I stared at it for a moment while he stared at me.We both laughed, he stood up put his dick away, we finished the conversation( I think) and he left. After he left I thought about the events and realized i was doing a lot of adjusting now too. I jacked off thinking of what almost happened.
