Is there some cuckolding action or erotic adventure with her black lover your wife/GF hasn't done yet that you'd very much love for her to indulge in? Maybe getting fucked anally, doing it in some outdoor location, going bareback...
What is it you desperately want to see her do for you? Don't care if she's yet to make her mind on trying it.
