Time for some people to start using Google to do a bit of research. First off you could just harvest the eggs from a white girl once a month when she ovulates. There is half the equation. Then you could harvest the cum from the desirable white male. You then spin his cum to separate the male sperm from the female sperm. Then in a dish you fertilize the egg and create an embryo. You can now place that embryo into any female to carry to term. The female that Carrie’s the baby to term gives no dna to the baby. So black ladies could carry a white female. This way the desirable white female could be used time after time.
how do I know this. Well I am a farm boy. This is how we breed pure breed cattle herds quickly using old dairy cows to carry beef cattle.
now I would suggest you keep a number of white males for break in purposes.
think of these desirable white females like a new high performance car.
only and idiot would fill the tank with high test gas and then stomp on the gas.
they have to be broken on to get the most out of them.
think of these white guys as mechanics there to insure optimum performance.
they would be there to bath these ladies. Shave these ladies. Insure all their fluids were topped up and they were lubricated. They would be there to insure they were not breed. Which would take them out of service for months.
these white guys could simply swallow the black guys load there by insuring the white lady was ready to service the next black guy. Or they could collect the black guys cum to be give to a black lesbians so they could have pure black babies with out having to have sex with a black guy.
