Just let me watch

My wife and I have had some interesting experiences over the last few years. It all started when we did a threesome with another man and recently, she did a threesome with another couple. She is a goddess, beautiful with dominant traits. My fantasy is to watch her fuck whoever she wants, how many she wants and doing whatever she wants, having others please her. And I just want to watch everything, as if I was watching a movie. And then, in the end, she would fuck me and confess, that I'm the only one she really wants and needs.
