Originally created to describe a more practical version of an unpopular sexual manuever called the "New Jersey Hook". The Yellin Beef Claw has several improvements over its uncomfortable and impractical predecessor. It's application is described as follows: First, the thumb is lubricated and inserted full length into the woman's anal tract during "doggie-style" sex. The meat of the hand is then wrapped around the ass cheek and, once a firm grip has been established, the full strength of the upper extremity can be used to pull the woman's body back and forth on the man's penis. Two hands may be used as well for added effect (AKA The Double YBC or The Shotgun Formation).
I gave her the Yellin Beef Claw last night and she loved it!!
