Also here is my first attempt at showing a GIF
(I need to play with the the timescale curve a bit more I think, the more I see it, the more I notice a bit of a jump in time after the penetration.) You'll see some cylinders on the inside, those are crew member stand-ins. sooner or later I should go about learning how to get a hold of a basic human model in a static sitting pose.
That was from a free gif from flv site, IMGFlip, though the framerate isn't that great. I may have to look into youtube next. I'm fairly impressed with the tool I was pointed to for recording the video: https://obsproject.com/ It was free, and pretty easy to record.
