Achieving a full hand fisting of your partner's anus of or vagina. Requires patience and lots of lube and very pleasurable gaping.
It took over an hour but I finally did the Five Knuckle Plug on her ass. That baby gaped for 10 minutes before it snapped back shut.

The act performed when a male or female inconspicuously inserts their hand into clothing of a female while in a social setting. A finger is then inserted into her vagina and is manipulated in way that will cause stimulation. The puppet master continues the finger movement as the puppet continues to interact with others in the public setting. The period of time the act is performed is often referred to as a "two knuckle puppet show".
The look of embarrassment came across Jill's face as the dog pulled down the jacket she had draped across her lap, exposing Jack's hand pushed deeply into Jill's Pants, causing their two knuckle puppet show to come to an end.
