Page 20, look at how the middle image almost cuts through the page really selling us on the force behind the thrust – not to mention the slumped-over doggystyle position implying a crushing sensation and how each of the auxiliary panels show the reader different angles which helps with the implication of speed since each different panel feels analogous to a different thrust.
From page 14; just real clever to squash the image into such a small panel. Best way to say “these characters are close” - in my opinion - is to literally push them together. Plus, all the saliva and breath clouds make the whole image reek of satisfaction. Also, note how the characters are shaded the same way off the pure white background: Only they exist in this space, and the fact that they’re shaded to the same degree which reinforces their spatial relationship (they feel like they’re right next to each other). All-in-all, a real intimate panel.
From page 11.... Just brilliant.
