...Creepy.

To put it mildly.

any idea who the author is? I have seen a pic of Leona from KoF deepthroating, and the style looks awfully similar.

look like mini vaginas

Come on, guys, that's Felicia... she just has cat-hands. It's nice :)

I'm more concerned with why the claws are out.

at gelbooru it's listed under eroquis. any objections?

Evidence suggesting this is the source, is that it is the only image in the gallery labeled "フェリシア" (Felicia), and there are no other records of another Felicia drawn by the artist.
