Three more RPGM. All western since almost every japanese RPGM with female protagonist fits the bill. All with free roam open world elements:
Succulence: one of my favorites. Completed. The beginning is unnecessarily convoluted but once you get the grip it's a very satisfying slow corruption game.
Lisa: In development. Top notch visuals. Mixes free roam with some very long scenes (in effect, some "visual novel" parts) mostly seamlessly. Many hours of content so far and very reliable dev.
The Office Wife: In development with many hours of content. Starts as a NTR game (I believe the correct term is Netorase, also MC's man enjoys the sharing and cheating so...). The lewdity of the scenes really ramps up. It has some extreme fetishes like bestiality (avoidable).
