What is the name of this hentai piece with a simple artstyle and a gray skinned girl

I saw this on a discord server and then later somewhere else but it is a collection of still images 2 i think of a gray skinned, horned devil girl with a tail with a spade looking thing at the end of it. She is laying down on her chest and from the behind the camera and a man is. The man is taking of her underwear and she is saying something like "wait what?" or just "what?" the next photo is off her laying on her back naked with a penis infront of her pussy.
