Most incest games I know of are incomplete/work in progress but some of them are worth trying like:
Dating my daughter; you can choose how the story will move and you can avoid things that you don't like, is a romance between a father and his daughter, they have been apart for many years and they slowly discover that they like each other... like a lot. Is a clean and deep story without coercion, rape, or blackmail (and I hope it stays that way).
Man of the house; there is some blackmail content but is not the nasty offensive type is kind of comical and the sister involved in this situation comes around and likes where the situation go with the MC to the point of keeping up the situation even after her brother doesn't have any leverage on her, she likes the game between her and her brother and their relationship actually deepens and they start to like each other.
Then most of the games here rely on some form of rape, blackmail, cheating, tragedy and even worst tropes, there are very few good stories in this kind of game, but some games give you the option to avoid disgusting content so sadly you have to try them up and see if is something that you're comfortable with.
