Hello, i can confirm that there's at least 1 pose (in Free Mode) Futa Nishy x Harpie (being attacked by a wild harpie), as Harpie would stroke Nishy with her bird type feet. Also putting legs in mouth, however it's more about vore (Nishy x Fairy, putting half of the fairy in her mouth). I think there where a few thighs poses, but i can't recall for sure (i do remember there's exp for that, so there should be at least 1 pose) .
I hope this helps, for more insight i recommend checking the videos above (game trailer, walkthrough videos), although they might not contain the desired kink, and they don't show any of latest updates (Fairies).
Cheers,
~NK
