Anybody here reading/caught up with the anonymoose saga? It has lots of monster girls, actually plausible in universe reasons for why the monster girls want men so much, and is decently well written. I especially like the variety of monster girls they've managed to include, running the gamut in species and mentalities. Some want to wife men up, some want to enslave men into their slave harems, and others just want to see the world burn.
Another fun one is The Paladin of Avalon. It's a quest translated from some Russian imageboard, but the writing and translation are both very good, and heavily features monster girls. There's been too much focus on MC's loli succubus gf in recent chapters, but he has an arachnid girl, and may add a harpy, centauress, and cat girl to his harem at some point. Also recommended if you haven't seen it. Author also include drawings of the girls which is a nice touch.
Also, anybody know any other good stories, anime, or manga with monster girls, where the "monsters" aren't just nekomimi? So far, aside from the two stories, I've only found Monster Monsume, which is painfully generic, and A Centaur's Life, which vacillates from boring CGDCT to balls to wall crazy.
