You are right. The best scene are amateur interracial scene where you can see the the vibracion between bought. In my opinion if you want to seduce your wife and make her thinking of a bbc bull you need to find a scene where the excitement must be very hight. The woman's face must be in sock and in pleasure in the same time. Giving her strong orgasms will make all the woman to think if she will receive the same for a bbc bull. When the excitement is on top of the universe and the mood is perfect she will want to have some experience as well.Seeing the reaction of the female is the most important part of interracial porn. Of course, it is stimulating to see the big black cock invade the white pussy, but seeing the woman's face and hearing her reaction reflects the true heat of the moment. Video that only shows genital interaction is boring and I turn it off in short order.
So in my opinion real amateur interracial scene are the best for open a new world.
