. A few select white males can be kept with their nuts entact to produce the sperm needed to keep the operation going but they would have their little cocks caged. No white male would ever enter a white pussy again and it can be determined by the sicenitist as to what males provide the best sperm for the best white females and they would someday be able to control all aspects of the white female for the Black males to enjoy as they like.
are you saying after having their sperm harvested some number of times ( say 2), that they be given a vasectomy, castrated or put in a chastity cage?
my personal preference would be to also breed white males, but breed them to be more fem, so that BBC can use them as well. I figure it would be especially mean to let the white males experience pussy at least one in an attempt to procreate, then never getting it again. After their one shot, the white males would be kept in a chastity cage with spikes, to train them not to get erections, with the key held by a white woman at the institute. They would also have a vasectomy incase they get out. The key holder would send him pictures of herself and communicate to him to humiliate and degrade him for having a small penis. This would further train the white fables to look upon the white men with disgust so when they are in the wild, if any approach, they will be rejected.
