New tools and new interactions for pre-existing ones;
You can now use the penis on the butt and the mouth (there's an animation issue with a couple of mouth poses and the penis that I'm trying to solve), and the tongue on the mouth and butt as well;

In terms of new tools you now have hands you can use to play with all areas, as well as breast pumps for breasts;
I can now tweak the body proportions for each girl as well, so you will notice a bigger difference between each girl!
