Incredibly, I was able to create a very solid rough motionwork in about a single day, allowing me to make fantastic progress from the beginning of this project. I am extremely proud of the result, so far.
As you can see, I've chosen this panel to animate, where the man in the scene presses firmly down onto Kyouka's abdomen/womb as he thrusts into her, causing Kyouka to wince in shock.
