Great topic
I know the media like to portray white women as vulnerable sexually but the truth is white women are actually quite tough. They can take BBC better than all women including Black women. White women are also champions of anal sex which is feared by Black women. It weird but white women can take BBC no matter how big it and no matter how tight, she can take it with pleasure.
White women also have great resilience sexually especially with gangbangs combine that with the strength of Black man. It a perfect combination in my opinion. With that being said I think white women were built for BBC. The body of white woman was built differently which is perfect for Black man.
Your wife has an amazing ass by the way. Since she is BBC virgin try her with gangbang of three guys and see how well she will take them. You will be surprised.
