A girl arrives at the anal clinic complaining of discomfort in her buttocks. Under the pretense of a physical examination, she undergoes cruel treatment involving the forced expansion of her anus using various instruments. Lying naked on the examination bed, her anus is first loosened with fingers, then penetrated with a dildo that is repeatedly thrust in and out. Finally, an extremely thick, long anal device is inserted and used with such force that it violently expels from her anus, completing the brutal procedure.
