From Spanking Art

Marm (short for Marmalader?) is an artist who creates adult rendered art and cyclic animations with Source Filmmaker (SFM).

Marm's work has a high degree of realism in its motion, squashes and wobbles. Most of his oeuvre are sexual intercourse or masturbation scenes, but Marm has also done a few works of M/F and F/F spanking. Marm's preferred genre is adult action in science fiction/fantasy settings, with some characters taken from computer games and films, and also includes occasional BDSM elements such as bondage and ball gags.
