cervix play with beaded sound

This sound has little balls along the metal rod, each one larger than the one before- it reminds me a little bit of anal beads. With my tunnel plug holding my cunt wide open, I used the sound to stretch my cervix open, one bead at a time, until the toy was going right into my uterus. You'll see me pause to use my vibrator in between shoving the toy further into my womb- I swear that arousal helps my cervical os relax and take more! The stretch feels so good, and I cum over and over, with my pussy squeezing the tunnel plug and my cervix moving and waving the sound in the air.
