I love the fact that my wife fucks any guy she wants whenever she wants. She doesn't even have to let me know and I don't need to be there. She gets a lot more cocks when I'm not around. But she always makes sure she is wearing her wedding ring with every guy she fucks.
of course I will kiss her on the lips, it will wipe everything clean and you can kiss. but the very thought that these lips have just been sucked by another member, that they have recently had another man's sperm on them, turns me on very much
