With a Collins speculum holding my pussy open, my huge stretched peehole hangs down obscene and obvious. I shine a doctor's penlight into it, then slide it right in, so that you can see the glow as it's engulfed. Then I want an even closer examination, so I put an endoscope all the way into my bladder and take a look around. I pee while I'm doing that, so that we can watch the walls of my bladder change texture as my bladder shrinks down. When I pull the endoscope out, can you see how the piss has pooled in my cunt?
