Start her off with interracial porn. Then go out have drinks with me followed by inviting me over and I'll do the rest. She will never be the same. And you marriage will definitely benefit from it.
We are a white couple into cuckold relationship since last 5 years now... at start my wife was nervous and shy but after having 5 years of exp now, she only say one thing to me and that is "Thanks" .. we both are happy and satisfied .. Thank you BBCs for spicing up our marriage life..
