Miss Taylor has found you in the girls dormitories so she has brought you to my office. When she caught you you had your hand firmly in your pants, playing with yourself. You do understand you will have to be punished for this disgusting behaviour you little pervert. You St Hugh's students are always pushing your luck, which is dangerous because we can be unforgiving when we catch you. We explain that once in chastity only Miss Taylor and I will have keys. The only way you can hope we may unlock you is by stripping naked in front of all the other boys in your school and showing you are locked in a chastity cage. Then, and only then, we may let you out, as you will have served as a warning to all the other perverts in your school. So drop your trousers and your pants so we can put you into this cage, and by looking at you it is a very good job I have a tiny size!
