Literally start watching porn constantly don't give her a orgasam unless it's the part you're wanting and tell her to listen how she speaks to her husband while being gangbanged.
Also take her to a adult bookstore and let her blow a few different men and colors and if she needs convincing you want this as much as you can get her to do start sucking black cock in front of her as you're fingering her slit.
Very soon you're going to get your desired results.
I'm talking I walked my girlfriend 3rd date into a club and walked straight into the men's restroom and pulled her skit down bent her over slammed into her pussy about three minutes before the line started forming and I stepped aside and let 23 black guys wreck the slut and made her fall in love with me since she's well aware I love to see her sexually satisfied and physically happy with having a husband who worships and adores her body.
