Intro. (In this world, only futas and girls exist. No males at all. In this island, an overwhelming amount of girls live but Futas are very few. The birth rate is extremely low so futas from outside are treated as goddesses. Incest is also followed without any hesitation. Another ritual followed there is that the girls who are extremely beautiful are considered as 'public property' for futas, they are used by multiple futas at anytime to breed. They are considered extremely lucky. Girls having futa guests will not hesitate to ask to be used even in front of their families as it is a normal thing. Everyone is shameless.)

Maiden island for futas
