Had to share a room with co-worker due to unexpected storm. No flights out and hotel rooms all booked. We are same age, work in different divisions of company so only know each other on job. I had the room reservation. He asked if I would mind if he shared room . No issue - of course. He is married, no kids. We grabbed a few beers and dinner in hotel. Went back to room, put ball game on, did some work on laptops and hit the sack. Had double queen beds - nothing happened ... until morning. I am up at 5AM everyday. Went to hotel gym for 45 minutes and returned back to room to shower and get ready for meeting. He was still asleep. While in stall shower, he came into bathroom and asked if I minded if he took a leak - told him to go for it. I had my back to stall door with shower blasting so never sensed his presence coming into stall until two hands were on my back. I immediately reacted by jumping and turning around in shock and now the hands that were on my back now fell on my dick. He said not to be freaked out - just 2 guys sharing a shower. We did not say a word - he finished soaping my entire body, rinsed and he asked me to do his back and ass which I did. As I left stall for him to finish, he grabbed my dick (I was hard) and said nice cock man. He slapped my ass and said thanks. That was it ... I got dressed, went to meeting and flew home. We still run into each other at work a few times a week, say hello, small talk, but it is like nothing ever happened ... in some ways nothing did.
