eugenics orgy islands near Japan

Like in all those hentais, it was made so that Japan actually had these islands hidden off its coasts to the east, filled with people bred and selected so they could become willing bitches of the world's best quality. At first it was just an island where men with small dicks were born and girls were born with big tits, asses, and loved fucking whoever ordered them. Additionally, the men were little bitches, so usually just got their dick sucked on the regular, perpetuating this sexy culture whilst making women available, eager, and never having experienced what's considered small or big dicks from the mainland. This island was still advanced, but it was tucked away, left only for the elite to enjoy like kings, possibly bringing beauties home if they wowed them enough.

However, this wasn't the only island, and after the first island's massive success, other islands were made or upgraded to house women of different tastes and forms, creating an archipelago of hot bitches, with something for everyone if you look hard enough.
