Augustine is definitely a kindred spirit even though I’m not into bondage or enemas or low-grade torture. I like it that the dommes he draws are sexy and casually cruel and the subs are helpless dweebs. And there’s usually some CBT involved. I’ve never run across any site that Ausgustine owns or runs, I just pick up his images in random places.
Baron Chungo makes some very sexy extreme Femdom. Unfortunately, he stopped producing a new art about 4 years ago. I will be posting almost all of his online content with the exception of a couple female-on-female pieces. Here are his 3 sites/blogs:
1) Woman is my only God
3) Baron Chungo
Coxbones does a wide range of Femdom scenes other than castration. Here is is DeviantArt profile.
