I have seen more than few suggestions that drugs (for the gerbil) might also be helpful. One might lure the gerbil up the tube with a piece of cheese, or, inversely, light a flame under the funnel to send the gerbil scurrying. Some accounts suggest that the gerbil should be declawed as a safety precaution, but the main gist is to have the gerbil burrowing around one’s anus long enough to bring about sexual pleasure. In most instances, it involves a tube up the ass, followed by a gerbil up that tube.
The act of gerbiling, according to the Internet, is simple.
