User surprises me while shooting and I have to abort 08 N

At the moment I'm enjoying the last autumnal rays of summer before it gets icy cold. And what is the best thing to do outdoors in connection with the sun? That's right - turning! Everything was going so well until... a user disturbed us permanently. When we had set up and placed the camera, he already came once. And then, when it came to the action. An extreme strange and unpleasant guy !!!! And in the end we had to break off. I think I need my time now to be able to shoot outdoors again, because this experience was extremely unpleasant. I don't think it's bad to be watched or seen during sex. But not being left alone crosses boundaries! What would you have done in this situation? Kiss Ruby
