Great advice. I've done much of this already. My wife falls into the "never will category". She loves watching interracial videos with me during sex, I gave her a big black dildo that vibrates. It's long enough to put between my legs and fuck her with it. She usually asks for me to fuck her ass when there's a black guy giving anal in the movie. She loves the fantasy of black cock and loves the black dildo. I tried to encourage her to use it while I'm away too but she is too shy.
