Alternative spellings: fistfuck, FF, handball.

To insert your whole fist in a(nother) womans's vagina/a(nother) man's/woman's anus. (This is known as handballing).

Vaginal fisting is - in the author's opinion - INCREDIBLE if done correctly, but handballing is not - and never will be - in their repertoire.
Sasha lay on her back, Kristen on her side. First of all, a finger at a time was placed inside her vagina, then eventually it worked its way up to the whole fist (More like a beak shape than a fist, if truth be told)and started to fist fuck her.
Whilst inside Sasha, Kristen swivelled her fist round and round, causing Sasha to moan in pleasure. Then, Kristen changed her hand into an actual fist shape, alternating between opening and closing it inside Sasha, who was now screaming for more, and swivelling the fist shape inside her.

Rectal fist insertion. An unusual form of sexual behavior.

Shook LL, Whittle R, Rose EF.

Rectal fist insertion (fist fucking) is an uncommon and potentially dangerous sexual practice. This is usually a homosexual activity, but can also be a heterosexual or an autoerotic practice. One known death has been reported associated with rectal fist insertion, in which the complications of anal and colonic tears and bleeding had occurred (see Editor's note). The possibility of drug overdose is also probable, as drugs and alcohol are commonly introduced into the rectum to promote sphincter relaxation and to ease the discomfort of anal dilatation.
