This is VERY true. The husband should be involved in the wifes breeding. He can lick her clit while the bull is fucking her on top of his face. He has a mouth and can suck cock and lick the bulls balls. An alpha bull will face fuck the husband as a form of domination and he'll do it in front of his wife to make sure she knows that they both will submit to the black bull. When the husband and wife are both involved together, the bond of intimacy grows stronger.
Husbands: Submit to your bull.
