I'm looking for the source of this image as well as a webm. Reverse image search hasn't helped as no results pop up.
As for the webm, all i can say is that it's webm of a hentai of a name which I do not know of, similar to the art style of Nishikawa, Takashi (his works like otomedori or Rance.) The hentai webm consisted of a girl being fuck by some sort of large animal, I think a gorilla. Please help if possible, I have not been able to find it in a while, plus I would like to know where the origin of this gif came from.
