There are a couple of still photo essays drawings by DeLucena, and 3D renderings by TurnKey and ShorterBus, but the bulk of the content and the real gems are the drawings by Tibool. These are masterpieces and hit me in the feels more reliably than a lot of modern photographic porn. Most of these appear to be set in the 1930's in an alternate world where female slavery is taken for granted, and being abducted to a farm or mine and worked to death is a normal fate for any female who isn't careful enough.
Tibool's slaves tend to wear long chain leg irons that are riveted in place so that once they are applied there is no key to remove them, and while they might be given striped prison shifts once these wear out or are stolen the slaves have to work naked. Tibool's command of body language, shading, and facial expression is incredible. A few favorites...

Lee-Ann escaped and got pretty far because she discarded her striped prison shift and stole a dress from a clothesline so she could pass as a civilian. The supervisor who caught her has given the dress back to its rightful owner and now Lee-Ann has to be dragged back to the farm naked. I love the expression of horrified humiliation on her face, as well as the supervisor's nearly bored and annoyed expression, which indicates that he is not worried at all that someone will call him out for dragging a bound naked woman down a public road. In the following pics she will be pilloried, whipped, and forced to dig her own grave. Truly a GIMP situation.

I love the physicality of this image, Sara's nearly manic drive to make her quota so she can eat and not be punished. But I also love the facial expression of the free woman watching her, who does not realize she is no longer free and will soon be joining Sara in her captivity. It's not clear from this pic but Sara is wearing the riveted leg irons that can't be removed as she works. She will die in this mine, as will the woman who is watching her.

Sara tries to escape but doesn't get far, and for her trouble she is crucified on the wall of a main pathway as a warning to the other girls. The caption says it takes two days for her to die but her body is left for another week before being tossed into the bone pits.
There are over a hundred drawings like this, all lavish in their attention to both the beauty of their female victims and the details of the environment around them. A few misfire but not many. If you didn't know about it, I highly recommend a look.
