Gave it a try, unfortunately it seems pretty masochistic, too much self-loathing for me.
First, i played through the hunting scene with the father like 40 times, trying to kill the deer, doesn't seem possible.
Then the scene on the bridge, played through that a dozen times, seems your options are to be a coward or lose regardless.
Then also there is a disclaimer at the beginning, which seems like if you turn off NTR, you don't get any content, just game overs instead... Which doesn't really make NTR seem optional, in my opinion.
Good luck with it, it's just not my thing.
