The Fist of Justice

Fisting (also known as fist fucking (FF) and handballing) is a sexual activity that involves inserting one or more hands into the rectum (anal fisting) or the vagina (vaginal fisting). Fisting may be performed on oneself (self-fisting) or performed on one person by another. People who engage in fisting are often called "fisters". Fisters have developed a distinct subculture with its own history, norms, and values, including literature and clubs for sexual, social, and spiritual exploration.
