Triple Anal Fisting
The act of inserting three (not two or one, this is very important to remember) fists into your partner's anus. Please note that this partner can be male or female. Also note that it is highly recommended that the individual receiving Triple Anal Fisting treatment should wipe before hand.
A man had a scratch deep within his anus that could only be cured with the force of three different fists, thus reaching the state of Triple Anal Fisting.
