The vibrating strap-on liner can be placed in a strap-on or in panties to have some secret pleasure. You can use this on any part of your body for pleaure and the silicone is really easy to clean. You just insert the 7-function bullet into the liner (or use the bullet alone!), press the button on the bullet to get to the function you want, and you're off! This liner also comes with a sample of toy cleaner, lube, and a silicone blindfold.
