Sometimes the officer in charge doesn't like the look on a prisoner's face and sometimes he's just having a bad-fucking day. When he wants to sternly lay down the law and keep every miniscule movement of the prisoner's in check, he makes his voice heard loud and clear. This sexy prisoner is sternly taught how to obey. Notice how self-conscious and nervous he is by the end of his strip search. His body doesn't belong to him any more. It belongs to the guards to ignore or abuse as they wish.
