DESCRIPTION
There are a lot of little animated interactions that I need to make for the scene, so far I have the idle animation for both characters, an erection animation, a pre-penetration sequence, the full hot-dogging motion (not visible in the GIF), a dick-slapping animation you can play on a command, and the anal penetration sequence. Lots of stuff! But still more to go.
At the moment, I'm working to add the anal penetration art. I want it to look like a really tight fit so I'm working on a system to automatically stretch the anus to match the exact girth of the shaft.
