A butt plug is a sex toy that is designed to be inserted into the rectum for sexual pleasure. In some ways, they are similar to a dildo, but they tend to be shorter, and must have a flanged end to prevent the device from being lost inside the rectum.
Fetish plugs are butt plugs that are designed in a way to be unusual, exciting, or unique in some way. A fetish plug is called such because it caters to male and female sexual fetishes.
One of the most common types of fetish plugs is the butt plug with faux animal tail. The animal tail, usually made with fake fur, is attached to the non-insertable end of the plug so that when worn or inserted, the impression is given that the wearer has an animal’s tail. Some “tail” butt plugs popular in human puppy play are moulded from medical grade silicone allowing a simulated tail “wag”.
