Using an endocervical speculum to spread my cervix open always makes me a little nervous, but it also makes me cum so hard. I show this from both the outside, so you can see how my hands shake and how my pussy squeezes the tunnel plug when I cum, and also film using an endoscope inside my cunt, so you have a close-up view of my cervical opening being stretched. It's a little painful, but I love it, and I think you'll be able to tell that! I nearly cum just from the speculum, before I even reach for a vibrator.
