And they hadn't finished with me there, after that, they literally spun me around and did the endoscopy! They assured me that they were not going to use the same camera that had just been up my anus. Saying that, I really didn't care, I was still higher than a kite from all that endless sucking I'd done less than a minute ago! The cylinder / tank must have looked like an empty crushed coke can.
