Ready to drive yourself — or a partner — over the edge? With a flip of a switch, any one of these machines is ready to take you as far as you want to go. Best of all, they don’t stop until you say so. For Masters, a session on a fucking machine is a great way to test how much your sub can take; or a loyal sub can take a solo ride to build up their strength for Master. However you want to use them, these powerful, inexhaustible devices are a great way to take your playtime to another level.
