Fisting, handballing, fist-fucking, brachiovaginal, or brachioproctic insertion is a sexual activity that involves inserting a hand into the vagina or rectum. Once insertion is complete, the fingers are either clenched into a fist or kept straight. Fisting may be performed with or without a partner.
The beak-like "silent duck" used in the initial stages of fisting.
The "Silent Duck", also called "Duck-Billing", is the technique often used in which the person engaging in hand insertion shapes the hand to resemble a duck's beak. Typically, fisting does not involve forcing the clenched fist into the vagina or rectum; this is a practice called "punching". Instead, all five fingers are kept straight and held as close together as possible (forming the beak-like "duck"), then slowly inserted into a well lubricated vagina or rectum.
In more vigorous forms of fisting, such as "punching" or "punchfisting", a fully clenched fist may be inserted and withdrawn slowly.
Fistees who are more experienced may take two fists (double-fisting). In the case of double-fisting, pleasure is derived more from the stretching of the anus or vagina than from the thrusting (in-and-out) movement of hands.
Anal fisting carries risks of colorectal perforation; participants are advised to use latex gloves and lubricant, and designate a safeword, the utterance of which will call an immediate halt to the activity. The practice, along with the insertion of hard objects into the anus, has been significantly related to the traumatization of the rectal mucosa in increasing the likelihood of infection, including Hepatitis B.
