Specifically wanting monster girl loli games rather than monster girl or loli femdom games narrows down the list of games more than I'd like, but here are the ones I know of with at least a little bit of it.

-Cornelica, Town of Succubi
-Desire Dungeon
-Succubus Senki
-Mage Kanade's Futanari Dungeon Quest
-Get Violated By EVERY Girl You Encounter RPG ~MAX Volume!~
-Naughty School Ghost Stories
-In the House of Temptation (This one's on a rather specific site so I'll spare you the effort of looking for it. https://textadventures.co.uk/games/view/v55rs5xbfkeh9pqjaxgauw/in-the-house-of-temptation)
-Lolibabas of Mayohiga (I haven't actually played this one and I can't even look at the DLsite page, but I assume it's probably a lolibaba femdom game)

I'm probably forgetting some games and there might be some in my backlog that I haven't played yet. I might mention them later if I remember any more.
