3 some or watch?

As someone who hasn't done it yet. I really don't know. Started off wanting to watch her suck while I fuck her or her sucking me taking another cock. I still want that but also want to just watch her cum on another cock as he explodes deep in her. Slowly but surely we are getting to that point. Also want it to get to the point where she just fucks whoever she wants whenever she wants. As long as I can fuck her after when she's full of cum. Or not, just want her being a total little slut.
