I have an idea for your next story:
Title: Tree of fertility.
Plot:
In this African tribe a young woman who has reached the age is selected by the tree of fertility to carry the next generation of the tribe in her womb. She goes through an ancient ritual where she lays on her back and the shaman pours zap on her belly to intiate the process and do a bunch of chanting, this cause the young lady to become pregnant with more babies than she can count (the number of babies in the womb is up to you). Now she is tasked to be the tribe’s breeder.
