I inserted my Kogan endocervical speculum and stretched my os cervix open, the prongs creating a peculiar rectangular gape. Then, I used a surgical steel sounding rod with balls of increasing size to penetrate past the internal os and all the way into my uterus. You'll be able to hear from my moans that I could feel every bulge pop into my womb! This clip has a mixture of endoscope views and footage from my main camera. Combining the strange sensation of the speculum stretching me with the arousing pain of the sound deep in my uterus was extremely intense for me, and my orgasm was so satisfying!
