A long, long time ago with another wife (almost another life) it was in the water at a public swimming area at a lake in south-east Oklahoma in full view of several dozen people. Of course I guess I should say that the cloudy water made it impossible for anyone to actually see what was going on but I have to wonder what the fish thought.
Let's see would that be considered "fucking" or "spawning"?
BTW, I wouldn't recommend under-water sex no mater what you call it. As I recall we were both pretty sore afterwards. You see the water washed away the natural lubricant. A horny couple in their early twenties fucking each other's brains out in public can create quite a bit of friction. <img border="0" alt="[Fun]" title="" src="graemlins/fun.gif" />
