This happened 20 years ago on a visit to Luxor.
We were staying in a second floor hotel room. On holiday with a gay friend. We had been out for a meal and drinks. My mate had gone to bed, I could not sleep and decided to go onto the balcony as it was so warm. Getting myself a gin/tonic as I looked around the empty streets it was about 2.30am. I noticed a rather good looking army lad. He was on duty. He noticed that I was watching him. He stopped by a lamp post glancing up every so often.
At this point I was getting horny and thought I must give this beauty a show. I must tell you I was dressed just in boxers. I slipped them off. He at this point kept his eyes firmly fixed on me.
I was nice and hard. He could not get a full view as the balcony bars were in the way, he knew what I was doing though. I got a chair and placed it up against the wall. Stood on the chair so he could get a full eye full and slowly started stroking my hard dick. I wanted to cum there and then. But savoured it holding back to give my army boy a good time. It was then I noticed he was rubbing himself against the lamp post. This was driving me wild. I kept pumping away then it came I shot my load across the balcony floor. It was one of the best wanks I have ever had. He smiled up at me. Never did see army boy again but think of him often.
As I returned into the room I caught my room mate wanking in the door way, he exploded there and then. He had been watching me all the time.
