In life in wonderland your only goal is to enjoy your huge harem. Get them pregnant and spoil them (for them the best way to be spoiled is by you inside them). Here you don't have to spend 1 hour of conquest to get sex. Here everything will always be sex. in a country/island, in which you are the only man.

So if you want a porn visual novel. focused only on sex.

My dear friend. it's your story, the story of your adventures of sex and sex.
