Calisa offers to pleasure her professor in exchange for a good grade. In reality she takes pictures to try and blackmail him. She tells him that he has no choice except to raise her grade, but he proves her wrong. She ends up with her ankles, knees, thighs, wrists, elbows and chest all tied tightly, and her mouth cleave gagged. She tells the professor that it was just a joke and that she was never going to release the images. She struggles around and gag talks but is unable to free herself. Maybe if she just studied and did her homework, she wouldn't be in this mess.
