Yes, this would be perfect.
The Wives get a refreshment break with entertainment, the Bulls enjoy being sucked back to readiness to enjoy another round of fucking the white boy's Wife with the added kick of knowing it is the white husband himself that is preparing the cock to fuck his own Wife and the cuckold gets an opportunity to display his devotion to his Wife's happiness and pleasure as well as his respect for the man that is pleasuring his Wife for him.
Win-win-win.
Of course, then there needs to be a Female version of the glory hole utilizing "Queening" chairs so that, after enjoying a wonderful fucking, the Wives can go sit and relax while the cuckolds lick, lap and suck their cunts clean of all the sticky juices and cum they will undoubtedly be full of.
In fact, along with the glory holes for Black Men, there should be Queening lounges for Black Women that are also guaranteed to use only white mouths so that the Black Ladies might also enjoy being serviced orally whenever they wish.
