Shelter

The world's elite have taken shelter in an underground complex that will keep them safe. Some local girls in the area managed to find the the place on their own, and are banging on the door. The news is saying that the asteroid is going to impact in two hours. There are 20 people in the shelter, mostly old wealthy men and some younger wealthy men. There is enough food for two more people if rationing for ten year, by which is it hoped that the dust will settle and life can go on. Now the men are not stupid... they know that they will need girls to repopulate the world, and time in the vault isn't going to be any fun without any action. But they can only afford to let one girl plus her eventual child inside, so the three girls will have to square off in a duel. A duel to see who is the most shameless slut and the two losers will be left outside to die. The winner will gain the privilege of being pregnant, and when they finally escape the vault she will then get pregnant every nine months with a different man's child. Maybe two girls can be saved if they are exceptional...
