Couple more days

I told my girl about my fantasy so in 2 days I'm going to show her a lot of black on black porn with hung men and use a dildo on her while she says things like "fuck me with that black dick", its black on black because she is half black. Is there anything else I could do to help make this better for her. I'm trying to get her into the idea if fucking black men while I'm loyal to her.
