How does one improve on the tried-and-true butt plug? California Exotic Novelties has the answer. Adding a remote control vibrator that operates on two AA batteries (not included) might not be that radical a departure, but that is not where the innovation ends. The Anal Explorer has a soft latex balloon-like exterior sleeve that can be inflated with just a squeeze or two of an attached bulb, once the butt plug is inserted. The bulb has a special air lock valve so the pressure can be increased or decreased at will, swelling or deflating the butt plug to the desired size. It should be noted that overly-zealous users who continue to inflate the Anal Explorer will wind up with a herniated butt plug that runs the risk of bursting. Users should exercise moderation. The box copy claims that the "Anal Explorer is the most feature-packed anal device available to date and is sure to fill your every need."
