The nazi's would have no use for a worn out asian porn whore once the war began , they can't even use her in their brothels because waffen ss men or even german soldiers who fuked a woman of an inferior race would end up facing a military court. In the case of the ss, himmler had actually had ss soldiers shot for sleeping with or raping woman concentration camp inmates or women in occupied zones that were not germanic. The german army and ss and women brought over specially for their brothels either from germany or from occupied countries where a woman was judged to be 'germanic'. The german armed forces were not like the russians or the japs in that way, women prisoners were largely unmolested because they were seen as lower than animals by himmler .
They would throw her in the gas chamber.
The nazis didn't automatically slaughter black people, indians,asians if they were not opposing the nazi's plans for german living space in the east pf europe,because apart from anything else they didn't have the resources to do so {lebensraum} which is why the nazis only really were rushing to kill jews, slavic people,gypsies , especially if those people had links to communism, ,in fact there were african soldiers in the wermacht and in the foreign legions of the ss. Paid mercenaries basically.
But, if you had a lifestyle which the nazi's saw as subhuman, such as being a homosexual, a porn whore for instance, before ww2 began, the nazis tended to think hard brutal work to ,military style discipline in camps would reform such people,so they would lock them up for a few months and try to remodel them into ideal citizens,many were released before the war being sent to a concentration camp wasn't a death sentence but just a really unpleasant prison , .But after the war began ,they had no time for that, so anyone they regarded as 'asocial', homos, porn whores, perverts, chronic homeless people, some criminals who couldn't or wouldn't fight for germany, they killed them as well.
