Fists of fury does not have to be a dominant/submissive position, as once the first fist has been planted, it leaves the perpetrator open for attack from the other person. This dual fist action can be surpassed by triple fistage, then quad-fist domination (for instance 2 females may be fisting both the vagina and anus). Quad-fists-of-fury are not for the faint hearted.
