What do I need to do to get the last 4 in Harpy's(oral/spitroast),  Minotauress(oral narrow), Dark Knight last two in 3.35.1?

Harpy spitroast is: find the harpy breeding grounds (second location I think) and win against first harpy, lose against second.

Dark Knight: if you mean rimming arts, you need to lose to her in Mossy Expanse and get game over; if you mean the giving oral art, you need to meet her in the pub of Town of Monsters by sitting at the table and talking to intimidating lady.

I have gotten everything expect the 2 pass anilingus and do you mean flocking or something else when it comes to the harpy's
