Need a quickie and breaking out your Autoblow isn’t in the cards? The Rumbling Stroke Master will help you take care of business by adding a deeply satisfying rumbling vibration to your routing that might otherwise involve only your hand. Simply charge it up and select one of the vibration patterns while you stroke to your favorite film. Some men prefer to leave it around the head of their penis to use it hands-free and find that the vibrations are enough to get the job done without even moving it!
