Is it normal to get so aroused showing nude pics of the wife behind her back?

I have been showing off extremely explicit nude pics and vids of my heavy set Chinese wife to others for years. Most if not all my friends have seen many of them, hell they seen more of her genitals than her gyno! She thinks I am the only person to have ever seen he nude!

But this past year has been the ultimate thrill. My wife doesn't get along with her father at all, because of their sordid past. Me and him got to bond after nearly ten years of practically never talking to one another. One thing ld to another and he admitted to me how he always had a fantasy of fucking his daughter! Needless to say he has been my number one customer for her nude photos and vids! He can't get over how dirty his little girl can be sexually!
