The world ended, the power died, and cities burned. Now, my best friend, our stepsisters, and I are the last people on Earth. We've been trapped in this house with nothing to do except watch the world decay. After months of trying to find a solution or any other human being, we finally accepted that we might have to repopulate Earth. I admit that I've been wanting to fuck my best friend's stepsister for years, but I never thought that once I did, he would be watching and pounding my stepsister next to us. Everything got even weirder when they suggested switching. I hesitated, but I guess that if we're the last people on Earth, it doesn't matter who I fuck. When my stepsister put my hard dick in her mouth, all my doubts disappeared, and I stopped caring about the apocalypse. All I could think about was licking her tits, eating her pussy, and filling her with my cum.
