So the MC goal is to turn the world into a demon lesbian world? I swear every women he screws turns gay. lol
The only actually gay one turned bi,
in a large harem it's unreasonable to expect the harem king to be the only one giving them pleasure,
other men are not allowed,
so in turn all the females should be bi so they can also help each other out,
it is a bad taboo to be possessive play favourites and be restrictive in a harem,
it would breed jealousy amongst the members.
The expanded principal of a 3 way relationship a love triangle all corners connect.
