Years ago, a space cloud passed over the earth, affecting the women of the world, making them bigger and stronger. Thanks to that space cloud, the female gene became stronger, causing a decrease in the birth of babies. More women are born than men. Today, women are now six feet tall and very muscular. Women's immune systems also improved, making them less prone to all kinds of diseases. The cloud even affected men, shrinking them to a size of 1.40m at most, and making their bodies more feminine (femboys).
