There exists a twisted group that degrades women, records the process, and sells the footage to fetishists. Many of their fans are particularly obsessed with the anus, and among them, women with thick, voluptuous buttocks are subjected to extreme training—forcing open the hidden bud to its absolute limit, continuing until the anal passage becomes completely slack. The victim is violated in both holes with a drill vibrator, her anus so destroyed that enema fluid gushes out endlessly. In such a ruined state, the only solution is stuffing a golf ball inside—an act of abnormal cruelty depicted in full.
