After being publicly humiliated in class, I ran back to my dorm room to put on some panties. However, the principal was already waiting in my dorm room to reprimand me. He makes me bend over and spank my bare bottom 30 times. Once my bum is bright and red, I ask if i can put on a pair of panties and head back to class. But the principal has other plans. He gives me a buttplug, and says i’ll need to put it in now, and every morning before lecture to always remind myself to wear panties! I lay back on the bed, and push the plug into my tight little butthole, then pull the panties on over it. I stand up and try to run off back to class, but the principal says he’s not done with me yet. He makes me spank myself another 30 times, over my panties with my butt plugged. Then he makes me lean over my bed, pull my panties to the side to show off my sparkly plug, and paddle myself 20 times before he sends me back to class.
