I had a few pictures from the artist. I think it was some ex disney animator who drew them. The chick looked like this except she wore armor. there was a one where she was holding a goblin by his penis for example and another where some big ogre or whatever was railing her.
Please held held me find the artist or even an image from him.
I have looked on rule34.xxx with every tag i can think of with no luck.
I really doubt this is the one you are looking for. But it reminded me of it:
