Love watching this. It took me until I was 39 (a few years ago) to start meeting women who loved having two cocks in their mouths, or pussies, at the same time. Now I've experienced it, women who don't want that seem a bit vanilla.
A few studies have shown that a significant % of women have a crush on their father in law. I know I found my mother in law attractive. But to actually cross that line and fuck your sons' wife, seems degenerate.
