The poor patient is strapped into the gyn chair with his legs spread wide while two very wicked nurses prepare his special anal treatment. They carefully position the fuck machine, make sure his ass is perfectly exposed, and then switch it on. From that moment on, the machine does exactly what it was designed to do while the two nurses stand beside him, watching every reaction with far too much amusement. He can moan, squirm and complain about his treatment as much as he likes. His nurses are not interested in sympathy. They simply adjust the machine, keep his ass exactly where they want it, and enjoy watching their patient discover just how thorough this particular therapy can be. For the nurses, it is another successful treatment. For their patient, it is a very long appointment with a machine that does not care how much noise he makes.
