Sadistic female tutor drips hot wax on her student, telling her to concentrate and not give in to the heat. Finally, the day of the exam arrives, and the tutor tells the student, "Lick my pussy and you'll have energy before you take the exam." When the student's exam is over, the tutor says, "You've been wearing a chastity belt for a year and refrained from masturbating. Today, you can masturbate while looking at my pussy." The tutor places a Sex Doll against her pussy and tells the student, "If you put your penis in this, it'll feel like you're having sex with me." When the student ejaculates, the tutor says, "You'll forget what you learned in your studies, so all your sperm." On the day of the exam results, if the student fails, the tutor smiles and says, "You'll have to refrain from masturbating for another year and study with me," as she puts the chastity belt on the student. This tutor is a bad tutor who makes the student fail and makes him her sex slave for another year.
