Can anyone tell me which CG this is?

[Primename]

Hello! I was wondering if anyone could tell me which CG I'm missing? I've already unlocked the vast majority of them and the only ones I'm missing are some variants and this one. I tried looking on the wiki to see which one I was missing but I couldn't find it.

Spoiler: My CG Gallery (NSFW)

Thank you in advance!

Gonna tell you a secret the big devs dont want you to know, you can look in the games files to see the CG's to see it and figure out what it is. But its probably the evergreen facesitting.
