This struck me as an unusual image. When body marks are shown in femdom artwork (or in any BDSM artwork for that matter), it’s usually the stereotypical cane or whip stripes. It’s rare to see actual bruising or more general signs of physical harm. The contrast in this case between the composed elegance of the mistress and the battered appearance of the slave is quite beautiful.
In terms of the backstory here I’ve no idea what the original artist intended. But with the careful pose and the photographic studio style backdrop, it comes across as a formal portrait session. Perhaps she’s preparing the shot for her annual Christmas card?
I’ve no idea who the artist is. It looks like something from renderotica and has some similarity to xrenderer, but I don’t think it’s quite his style. It’s an amazing piece of work, so if you do know the artist then please drop me a line.
