What isn't there to elaborate on?! Is every building a brothel? Or a love hotel? A sex shop? Are all the locals buxom women who throw themselves at any man who has reached his prime? Is there a single protagonist who receives the lust of all others? Are visitors captured and forced into sexual servitude? Are there orgies every night? Are meals eaten off naked bodies? Are clothes illegal? Is sex currency? There's many possibilities to a world designed as a fanservice exposition; never underestimate human degeneracy!
