Painful anal therapy in a brutal asylum

The video opens with a man in a white room, clearly a medical facility of some kind. He is bound to a bed, and a masked man approaches him with a needle. The masked man begins to administer a series of injections, which the bound man struggles against. The camera zooms in on the man's face, which is contorted in pain as he is injected. The masked man then proceeds to perform some kind of medical procedure on the man's anus, which is clearly causing him intense discomfort. The camera then switches to a close-up of the man's face, which is now covered in sweat and pain. The man's moans of pain are clearly audible, and the camera continues to zoom in on his face as the procedure continues. The scene ends with the man being released from his restraints and collapsing to the floor, clearly exhausted and in pain.
