Actually did show this to my gf and it worked not right away I had show her more over a couple weeks but afterwards she admitted she's always wanted to get spitroasted by two black guys
I imagine if a dude is really determined to make sure his wife knows he is a cuckold for sure and obsessed with stuff like this, that revelation will yield some sort of result. She'll probably just wish you hadn't brought it up and eventually decide she needs a divorce from you but you won't know until she knows right?
