5:46 video
Professor Calisa Bliss taught us in her first lesson the proper way to prepare a knotted cleave gag. Now these skills are put to the test in the form of a final exam where Professor Bliss will test the tightness, effectiveness, and mmpphh factor of being gagged with a knotted cleave while also tied to her chair. With professors like this, you'd go the full mile for extra credit yourself.
