Cunnilingus Machine
I have to admit, I made this but really I don't exactly know what the hell is this supposed to be. A cunnilingus training facility? A slave rehabilitation center specializing in 69-therapy? Your guess is as good as mine :)
I initially had the idea of making the forced 69 machine animation, which I thought would be a very simple thing. It turned out to be more complex and difficult that I imagined, with many layers overlapping each other. Not sure if the result worth it, but I certainly learned a lot doing this, mainly not to underestimate animation projects.
