Here's a little look at what I've done for Glory Hole RPG 2. Pretty much what you're looking at is the hair physics and the mouth movement. The hair is an obvious improvement from the first RPG, which had static hair. The side-tail (fuck if I know what you'd call it) uses new physics, and I think it looks pretty darn keen, the rest uses the same sort of physics as I've been using for a while.
The mouse control is pretty much the same for the end-user, but on the programming side it's a lot more efficient. I've made slight improvements throughout my flashes in this regard, but I've kinda locked it down now.
You can't tell too well (since there's only one dick here) but the mouth movement is dynamic, so the lips move over any size or shape of dick. Science!
Obviously there's a lot of work to do still, but I figured some might be interested in the two new features so far.
