Katie has been flashing the boys her thong panties at school so her teacher, Chichi, is going to teach her slutty student, Katie, a strict lesson. She gives her some full coverage panties to change into and inflicts hard wedgies and twists them up her crack to make it hurt. It's going to hurt so badly that's she'll never even risk showing her panties to the boys ever again. ChiChi measures the panties to make sure they are enough coverage! She ties them to her skirt too so her wedgie is nealy permanent! ChiChi yanks them so hard that she tears them. That will teach her a lesson!
