2B - From Behind Loop (Patreon)

I'm prototyping a new animation for 2B and these two loops are the result so far. It's going to be longer but I'm still unsure how I want it to be.

The motion right now is decent and the visual quality is good. Butt physics are acceptable, but I want it to be more interesting. Something needs to happen. My idea is to have A2 on the right watching. The camera then looks towards her for a moment, kind of scanning her body, then back to 2B, at which point it should get more intense. I've been wanting to make something like that for some time(having one girl watch).

I'm also trying different angles, as shown in the attached video files.
