It would be inspiring to envision a scenario involving a huge-breasted Walküre smashing through the Berlin Wall, or Ou Xiaorou cavorting naked on the Great Wall, but I'm sure the Captain wasn't thinking of anything so specific.
I assume the topic walls would embrace any kind of wall, indoor or outdoor, high or low, brick or plaster, with a huge-breasted model lying, sitting or standing on or near it -- or perhaps shackled to it and having her brains rogered out. That sound about right, Captain?
