Fistfucking

I can't believe that this chick is fistfucking this other girls ass. I can't even imagine how hard that is to get a fist in a tight little asshole or how it would feel. But, I know that my buddy has told me about some freaky chicks that he's been with and that they let him shove his fist in their assholes and double fist fuck them at the same time.
