I don't know if it counts or has already been suggested, but Black Souls 2 seems to have a pretty good count of monster/non-human girls.
It's a dark-fantasy RPGM game that takes place after the events of Black Souls 1 (IMO you need to play before the second), both taking place in a corrupt world filled with twisted fairytales. There's a lot more to the story than just that, but it's really hard to start off from the second game. The protagonist is also a bit of rapist too, how much depends on your actions which can be pretty damn often.
Can't remember the exact amount of monster girls because the game has quite a lot of interactions that are easy to miss, but off the top of my head there's harpies, a fairy (best one!!!), slime girls, bunny/rabbit girls, dragon girls, a wolf girl, unnamed zombie (i think?), and whatever kuti is supposed to be. Oh, and Alice, she's sort of a monster girl too.
