Fisting
Fisting or fist fucking (FF) is a sexual activity that involves inserting the hand and forearm into the vagina or anus. Typically, fisting does not involve forcing the clenched fist into the vagina or anus. Instead, all five fingers are kept straight and held as close together as possible, then slowly inserted into a well-lubricated vagina or anus. Once insertion is complete, the fingers either clench into a fist or remain straight. In more rigorous forms of fisting, such as "punching," a fully clenched fist may be inserted and withdrawn .Fistees who are more experienced may take two fists (double-fisting) in the vagina or anus. In the case of double-fisting, pleasure is derived more from the stretching of the anus or vaginal wall rather than from the thrusting in-and-out movement of hands.
