From hornyandwaiting: Very fun and enjoyable

Helps you squeeze more pleasure out of oral sex. The stretchy silicone ring sits firmly on your tongue. They have a small bead at one end to add a bit of texture and allow you to roll your tongue sexily around the clit and penis. Comes with batteries included so it's ready to use straight from the box, gives bigger and better orgasms over and over again then just your tongue.
