The Explore 4.5 Plug in Platinum Premium Silicone gives you full access and an unobstructed view of your bottoms back door. The textured, dual-finish exterior of this tunnel plug slides in and holds firm to keep that ass open for action, and a heavy-duty flared base keeps Explore safely in place while you insert fingers, toys, and more through the wide hollow center. Explores ribbed stem provides extra pleasure with every movement, and the open base can also be used for liquid play with your favorite funnel, nozzle, or tube toy.
