Kelli thinks she is alone in class, however she soon realises that is not the case when she sees you hiding under the desk. She knows you were perving on her sexy stocking legs and she is not impressed, especially when she sees where your hand is! She makes you drop your trousers & pants and laughs when she sees just how tiny your cock is. She tells you how Headmistress has warned her about perverts like you and has made sure she is equipped to deal with you. She goes into the classroom drawer and pulls out a tiny chastity cage & padlock with keys, explaining how she will teach you a lesson and she will lock you up. Kelli gets on her knees and takes you in her hands as she fits the chastity cage tightly around your tiny dick, and as she stands back up in front of you she looks even more beautiful & powerful than ever before. Kelli tells you that only she & Headmistress will have the keys, and you will have to beg to be released. She also tells you that you will not be able to get an erection or play with yourself until she thinks you deserve to be unlocked… I wouldn’t hold my breath of I was you!
