The BBC kink is incredibly racist, which (to me) makes a game unenjoyable. This abstract (

) does a good job of summarizing some of the various research in the subject, but essentially it boils down to:
1) It's supposed to be more humiliating to have sex with a black man
2) It implies that black men only have value to women in their sexual prowess and penis size and not other areas
3) It perpetuates the (very untrue) myth that black men and women were bred for large body proportions similar to live stock
To be clear, there's a difference between BBC and simply interracial sex (like Laura with that guy at the bar).
