Sitting in the lorry in three lanes of traffic was all I needed but as we slowly crawled forwards I noticed a car right alongside me. Looking down I saw a guy playing with his cock without a care in the world. His trousers were around his ankles and his erection was huge!  I was transfixed even though I hadn't considered myself anything but straight. That's what being married over 30 yrs does. 

The guy leant over and caught me looking at him and continued stroking himself as if putting on a display just for me. I was embarrassed that he caught me looking and he managed to get in front on my truck until the traffic started moving again.

For some reason my mind was racing and I couldn't get the image of his cock out of my mind.

A couple of miles down the road he indicated and pulled into a lay-by. For reasons I will never quite understand I followed in behind him. 

My heart was racing now as I got out of the lorry and walked towards his car...
