Edited my original post so people know I am not defending the bible.
The glorification qualifier is indeed a problematic one. I have yet to see such a game. Please do not link examples.
I will respect your request not to link examples. For people seeking examples, they are overflowing on cg pornography sites. If you want to know how's its glorified, victims are portrayed as objectified bodies to master and not characters who deserve empathy.

As for incest, I must admit I am confounded by how many people have come forward insisting it can be consentual. Incest is a form of abuse that takes advantage of the trust between relatives. Incest in the real world always involves coercion, violence, and/or children. This includes historic incest such as inbreeding in royal families.
Fictionalised depictions often write in that mutual desire and consent are there. This does not happen in reality. The fantasy of consentual incest has caused its real victims to face victim blaming and ostracization.
