My endocervical speculum gives me such a fascinating stretching sensation, opening up my cervix as wide as it'll go. This time, I attached an endoscope directly to the speculum, so that as it pried open my tiniest hole, the endoscope was right there to look inside. Then, I slid the endoscope forward until it was inside my cervix, to look right at the internal os! While looking deeper inside my cervix than I ever have before, I just had to grab a vibrator and make myself cum.
