Emily knows your bad behaviour is because you are frustrated but she won't put up with you being rude to her anymore during your lessons. She has decided the only way to deal with you is to get all your frustration out, she does this by instructing you to get your dick out of your trousers and wanking it in front of her while she teases you with her low cut top. You can't believe that one of your college teachers is sat in front of you telling you to wank over her, It's all your fantasies come true.
