Any cuckold games you recommend?
Sorry, i'm not a fan of the genre, so i can't point you to the "good ones". I personally like Mila AI, where there are alternative paths, one of which is plain cuckholdry, then there is sharing and faithful. The other games i like where LIs fuck around are all consensual sharing. Probably not what you ask for.
Anyway i think Darker is a rather good game so far. I look foreward to when it will get heavely psychological.
