I'm looking for a VN with a demon or some other supernatural force that is corrupting a...family? A town? I think maybe there were multiple chapters that focused on different people? I think there was an older and younger sister in the story, but not sure. I'm not thinking of Sensual Haunting, it didn't have sandbox elements. It kind of sounds like the description of Dark Neighborhood, but I don't think that was it.
ETA: I think it was a 3d cg game and there was some element of femdom or at least some aggressiveness by a female character.
