This clip starts with my cunt already held open by my big tunnel plug, giving you a direct view of my cervix. I use a 7mm treble sound first, moaning as it pops through my cervix and all the way into my uterus. Because I didn't have to work too hard to get it in, and because the plan I want to try requires my tight cervix hole to hold the sounding rod in place, I decide to take it out and try an 8mm sound. That takes some time and effort to get past the internal os! You'll see me struggle to get it fully inserted- but you'll also see how worthwhile it was and how excited I got when my cervix finally stretched and allowed it in. I gave it a tug to make sure that it wouldn't come out easily, and then I removed the tunnel plug while leaving the sound deep inside. On to the next part of my plan: putting my Lovense Dolce into my pussy so that the sounding rod would transmit its vibrations deep inside me! I'm so glad I tried this. I already love that vibrator, and it felt even more incredible with a metal rod wiggling inside my womb. Now I keep thinking about handing control of the Lovense toy to someone else, so that they could send vibrations into my uterus too!
