Kangoku Senkan and Cara the Blood Lord since they have the most realistic sex scenes. Kuroinu is also the same and only a few are very different.
@Aramos they aren't games, just text and enjoyment. Night and be well!
I would probably recommend Rinkan Club first, despite its translated name I found it to be the least intense. No monsters or anything. Kangoku Senkan next, its more intense and is more like what Lilith usually does but still no monsters or tentacles. Then if he was feeling brave he should play Taimanin Asagi.
And why do you got to bring Kuroinu into this? This was a Lilith discussion. You like that one better then Lilith now?
