Regarding Vixxxen blowjob scene, you would be likely able to animate that. The scene file is already in "almost0.671" build you have as vixxxen_oral_a.swf
All body segments are drawn, defineSprite objects ready. Just the main animation is 75 frames of intro only, no main sequence nor climax is animated yet. And no controls.
So you can animate that the classic keying way.
I thought of using scripts and movement math model for automated animation myself.
Regarding that Taurika picture animation, that's gonna be more challenging.
