One of the best things about my job is that I get to take lots of clients out for lunch. Which means that on a hot summers day it is easy to sneak off a couple of hours and go and spend a couple of hours sunbathing in their back garden. Or more likely enjoying all of the topless and naked ladies thaty use it - it always seems to be at its very busiest on a summer lunchtime. So the other Thursday I am starkers in the packed garden, next to a fantastically good looking petite Russian girl who was equally naked to me. I was enjoying the view but I also noticed the two nude guys next to me - they were clearly strangers, but seemed to be getting on very well with each other. After 90 minutes I was getting no where with the Russian girl, and I was thinking about it was getting time to go, when Inoticed the two guys next to me had started to very discreetly touch each other. As I watched I found myself getting more and more turned on, as they found excuses to inadvertantly touch, and my dick started to perk up. After a few minutes, they both got up and left the garden. Aware that this was going to be my only chance for fun before I left, I waited a couple of minutes prior to following. I eventually found them in the large steam room nearest the bar. As I went in I smiled at them and sat down immediately opposite them. THey were sitting next to each other, hands on each others cocks and had clearly been wanking each other. They were both hard (as I was I by now), one 4 inches, the other a much bigger 7'' I sat opposite, and put one leg along the wall and stretched the other out towards them. This gave the guys a perfect view of my erect cock and balls and I started to wank. I'm not gay, but I love exhibitionism, and the fact the two guys were enjoying watching me was really turning me on, and my prick was soon straining at its full 5'' length. I said "I'm about to come" and the guy with the big cock bent down and took the smaller tool into his mouth as I shot my load into the void between us. I left after that, but how I wished I could have told my colleagues what I really got up to!!
