prang prang

This means a vibration-based sex toy, often with a dildo attached to the end of the object that will move forward and back. It will be inserted into a vagina or anus for pleasure. It is named after the company "Prang" which designs and produces this series of sex toys.

I just bought a new 8.6-inch flexible huge prang prang and I had to feed it slowly inside as it is very flexible.
