All of the ones mentioned. The first two have a story build similar to here in pace. I like the writing here best, but then, I'm a horrible perv. The third also has a good story (and what looks like a higher def, older Samatha build, but can't be sure) but a bit of an instant gratification vibe.
This is my favorite, but having its "Related Games" reclassified has led to games with other great stories, even if not my kink. There are others with less of a sci/fi fantasy take, but I like what I like. And it is nice to have other stories to follow between updates.
