Slaved in Matriarchal World in Zombie Apocalypse

Noah is reincarnated as a 14-year-old in a different world. He lives with his mother, away from society. According to his mother, there are almost no humans left due to a zombie apocalypse that suddenly appeared. The death of his mother at the hands of a beast, leads him to meet the world, one very different from the one Nate's mother told him about and even the one Noah himself imagined. A zombie apocalypse grips the planet, unstoppable. When it seemed there was no hope for humanity, the will of the world gave them a gift. To the men, it allowed them to level up and grow stronger with the help of mana crystals from Zombies, mutated monsters, even from humans themselves and new races that have appeared on earth. Women, in order to preserve the species, were granted to level up and strengthen themselves through sex. Anyone would think that men would hunt beasts and women would turn to chasing men. But in the end this was not the case. Certain conditions changed the role of men and women in society. Now Noah, because of his innocence, ends up in the hands of a slave trader. Knowing that Noah possesses two of the greatest talents, he is taken to an auction in front of the most prominent women of all races. Unable to escape his fate, Noah must learn to live with his new reality, a slave. Warning: This fiction will contain great amounts of sex and violence.
