When you get screwed as much as these whores, it should come as no shock that their ass starts trippin! Each of the bitches in this film get fucked up the ass cause it's tighter than their pussies that have taken on years of abuse. These sluts have been fucked so much that even their sphincter takes a while to bounce back now, so you'll see some holes gaping WIDE open if you click through and watch Ass Tripping.
