Yes. Two things common with black men and unlike most white husbands. The black men stay hard for hours and they hold off cumming as well or they cum multiple times in any session. When the BBC is 9 inches or larger and thick this is a huge amount of stretching to the typical white wife unlike she has commonly experienced. That her pussy is so full for so long eventually creates an intense awareness of emptiness after he has left. She wants that "fufilled " feeling again and soon. And when the bull cums inside her there is usually so much more cum ( unless the bull is also active with other women ) than her husband gives her. Very primal. Breeding instincts kick in and she is so grateful for all his cum and wants more the next time and so on. Once these primal sexual instincts have been awakened , very difficult to turn off again and thus the apparent condition of all white women who have been seduced by black men
