Marina - Progress 9 (Patreon)

Quick mockup of how much you'll be able to see Marina when he's going up and down.

These are pretty much the only two key frames I think I'll need, apart from the toe curling, which I might do if I remember to.

You can expect a lot more physics in the final product, as the bed will of course have some spring and cause their bodies to move up and down a bit more dynamically overall.  But, each section of both Marina and the man will react appropriately in sequence with each thrust.
