I was visiting a club in Las Vegas a while back that allowed nudity.  While most people were dressed, I elected to undress in the hot tub area.  Many people would walk by checking out the club and everyone saw me sitting on the side of the tub totally exposed.  On this particular night, 2 cute young gals came into the hot tub area and both seemed a bit shy as they talked to each over and then looking me over.  I finally asked them if they have ever seen a guy masturbate and if they would like me to do it for them.  So they sat together about 7 feet from me.  I point a chair towards them and sat down.  By this time I was fully erect and tingling inside, knowing about what was to happen.  Anyway, I began to jerk while watch their eyes.  They were focused on me and my movements.  After a short couple minutes I could feel that sensation as the build up started to happen.  I then told them, "are you ready" as I started jerking a little harder.  It then then that I just let it go. They were far enough away from me that I didn't hit them with my cum.  After I was done, they smiled (as did I) and they left the hot tub area.  OH boy, what a thrill . . .
