We first got into it primarily because the GF and I wanted to view how each of us looked while fucking. Yeah you can film yourself but it is a real thrill for me to see a cock pounding her. She really likes watching me do missionary from behind. She gets so wet just watching my cock go in and out of another woman’s pussy

You talk, and decide, as consenting adults. It’s really not rocket surgery.
Love the expression “rocket surgery”
I’m quite fond of a good malaphor.
