Fisting

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 either naturally clench into a fist or remain straight. In more vigorous forms of fisting, such as "punching / punchfisting ", a fully clenched fist may be inserted and withdrawn slowly. Fisting may be performed with or without a partner.
