fisting

Fisting is a sexual practice that consist of inserting the entire hand, and sometimes part of the arm, into a pussy (vaginal fisting) or a anus (handballing or anal fisting). Fisting is also well known as fist fucking, sometimes shortened to "FF". The medical terms for these practices are brachiovaginal eroticism (vaginal) and brachioproctic eroticism (anal) respectively. For anal fisting, a silicone lubricant like Crisco is recommended (popular lubricant for this purpose amongst the gay/BDSM communities). Despite its name, fisting does not involve penetrating the clenched fist into the vagina or anus. Instead, all five fingers are kept straight and held as close together as possible (forming a duck's beak shape), then the hand is slowly inserted into a well-lubricated vagina or anus. Once insertion is complete, the fingers either clench into a fist or remain straight. Sideways hand-position is recommended for Double-Fisting, also called "The Doppelganger" but use of muscle relaxants (most notably "poppers") and lubrifiant are particularly needed to engage in this risky sexual activity.
