Nearly all of this video was filmed with an endoscope, inside the tunnel plug holding my pussy open, to give you the closest view of my cervix taking the steel sounding rod! I was playing with a 7mm treble sound, and you'll see how the beads slipped easily through the first os, making me gasp with pleasure. The second os was tighter, so I spent some time pushing up against it, working to get the angle and the pressure just right. You'll see how my pink flesh resists the intrusion, puckering and being pushed around, before finally yielding to it. I slid the sound deep inside my uterus, then pulled it back and played with the tight spot in my cervix, thrusting past it again and again until I had a satisfying orgasm.
