Pictures of anything that wouldn't be considered "normal" furry porn, but is considered acceptable fetish by the majority of the fandom. (bondage, bukkake, micro/macro, tentacles, oviposition, hypnosis/mind-control, etc.)
There was an old old sequence of pictures involving a dragon with big hair named icy (user iceman on furaffinity). His character was transformed female by a herm gryphon or bird in a grayscale sketch. Haven't been able to find it for years. anyone got a copy?
