Tied up and unable to escape, the only way out is to grind on the vibrating hitachi in front of me until I'm cumming. It's a bit of a challenge at first as the toy refuses to stay in place, keeping it just out of reach of my clit until I finally find a way to keep it in place. I lean back humping the vibrator, twin pieces of rope sliding through my labia and adding friction to the movement. Flushed and eager I cum hard, face turning a deep red as I finally find what I was looking for.
