A taboo family gathering takes a dark turn as siblings and cousins engage in a depraved game of "Asshole Dehnung," competing to see who can take the most extreme anal stretching.

The room fills with the scent of lube and sweat as they push their limits, their assholes gaping and red from the intense stretch.
