As a newlywed, my wife and I had gone over to Toronto for a weekend. After checking in, she asked me to go back to the car to get something. When I got back out in the parking lot, I noticed that there was a raised highway to the back of the hotel, and there was a fire escape ladder going up the back of the hotel about three stories to where there was a section of flat roof. I began to get aroused with the image of going up on the roof to masturbate.
It was more exciting because I wondered if I could be seen from the highway. So, not seeing anyone around, I quickly went up the ladder onto the roof. When I got up there, I realized that the guard rail would probably prevent most cars from seeing me, but trucks would certainly be able to. I looked into the glass door going off the roof into another floor, but it seemed deserted. I looked down in the parking lot and didn't see anyone. So I began to undress. Even though it was in the forties, I decided to take it all off, only leaving my shoes on because it was so cold.
When I took off my underwear, I was very hard and excited. My nipples were hard. I just stood there exposed for a bit with the traffic sound rushing past, wondering if a trucker would notice and probably get a hardon. At 25 I was flat bellied and had a good looking body. Then I started to stroke myself, looking around, but mainly focused on the highway, to see if I might have been spotted. (There was no way anyone could have stopped or approached me.) I found I was very excited by the outdoor exposure, and the cold encouraged me to finish the job at hand. So I kept at it and brought myself to cum without backing off. I shot arc after arc of beautiful cum out on the roof. I kind of hated to have it end, but I realized that I better hurry to get back to my room, so I dressed and climbed down. What a thrill!
