What's the nastiest, kinkiest, raunchy thing you're wife of girlfriend has done? Mine won't do scat, and doesn't dig anal, but has done pretty much all else.
She loves pissing on and for me or anyone else, has intentionally farted in my face, and once, possibly the hottest was in a motel once, I was hitting her doggy in the bathtub and she pissed and farted right as I nutted in her. She was a sloppy cum bucket that day.
