Agree, I think and know from past experiences most white cuckold couples are looking to both suck and both get fucked by BBC, what other reason would they seek BBC.
As an obeserver of social norms here in the USA, it now appears that many virile black men are simply finding it more satisfying to see their cocks being pleasured by the mouths and asses of young white boys instead of white women. A handful of women I know very well - who have trusted me enough to confide in my honestly - all now know that if/when they allow a black man to fuck them, they will also be expected to give up their female asses to those black men too. These women just know now that contemporary black men want to fuck ass. It is expected. These women all seem to have a reluctance to give up their asses so automatically. But a very large segment of young white American men actually go out seeking such black cock pleasures for their asses. Most white women view a black cock in their ass as and "inevitablity". Most young white boys view ma black cock in their asses as a desired goal.
