I'm an idiot and it wasn't a public post. Let me know if it's working for you now.
Seems to be working fine. Since the patchnotes says "Feel free to post where you like" I'll just put them here for convenience sake.
I don't need em much myself, I maxed out my stats before this update came out and my save seems to carry over, so...
There's also the cheats on the main menu too, but I just had to do things the hard way.
Anyway, the new pose is great, as are the 'intermediary poses' that you move her into to put her in doggy-style position.
It's a shame that the only action you can take is to fuck her doggystyle though. There should be ways to grope/finger/eat out Yuna when she's facing backwards too.
As-is all you can really do is pat her head until you reach the point in the game where you have the green light for fuckin.
Edit: A tracker in the stats menu for 'suspicion' would be nice too.
