Creepy Coloring Book Images

Not that Ethan's coloring ability here is worth noting. What is worth noting is the coloring book image itself that I find somewhat disturbing. Just what is the boy on the left imagining with his eyes closed, his tongue dragging slowly up the long shaft of frozen cream products, while a Larry Craig-like foot tapping/touching plays out.

The boy on the right just doesn't seem to get it. Yet.
