Whizzer Black is definitely one of my favorite femdom/ballbusting artists. He shows a lot of good emotion in his works, the girls are very hot, and somehow the exaggeration of the size of the beaten balls is erotic. Here are some works, I will post some mroe later. Enjoy!

Here is some very extreme femdom cartoons in color. These are by a great artist called torturepen. He used to have a website at http://torturepen.dk but it appears to have been down now for some time unfortunately. Hi artwork includes women buring balls with torches, electric shock femdom, cbt with swords, torture chambers, and more such highly imaginative things. He is without question one of my favorites.
