Dates in Bar Mills

So today I’m at this secluded spot on the river, I’m all alone splashing around in the water when this couple shows up. So I’m just minding my business enjoying the day when all of a sudden I turn around and she’s naked! He had stripped to his boxers but she was naked. I was trying not to be a creep but she was sexy and had great tits. So my question is , should I have said something? I was trying not to seem too excited, but by doing so did I miss my chance? Did I do the right thing??
