I don't remember much but what I do remember is that you live alone on a farm/small farm until a cat girl breaks into your house because she is trying to get away from a government group that is trying to get rid of all people other than humans which is actually run by the queen of succubus because of a semen shortage or something and more girls start living in your house and barn like a cow girl which lives in the barn, a mermaid which lives in the river, the cat girl, a dog girl, a spider who lives in the attic and more but I can't remember them all and one day two succubus come to your house and turns out your semen is really potent and could feed all the succubus
