Outdoors, a couple in love had sensual sex

We are all descended from fish - there is no doubt about it, which is why we are so irresistibly drawn to flowing water or even waterfalls. Well, this couple even chose such a place for sex. But still, there is something purely erotic in this - to copulate, imagining oneself as some kind of beluga or even salmon!... Well, there is a huge amount of romance in all this!
