Sometimes, when I'm approaching orgasm, my hips just have to move... so this time I braced my sounding rod so that I could hump my cervix onto it. Along with the tunnel plug I usually use to hold my pussy open for cervix play, I was using an 8mm rosebud sound in my womb and my zumio pinpoint vibrator on my big clit. After I came, I wanted to see the little round gape that the sound caused, so I took it out of my cervix... and then couldn't help myself and fucked my cervix to another orgasm.
