塔蒂 (Tatti) 的一位学生一直很难教好他，他一直很努力，但就是无法掌握数学学位的某一部分，因此需要额外的帮助……两人的关系开始紧张，因为他们都没有取得任何进展。塔蒂 (Tatti) 最后一次解释她的方法时，发现自己被她的学生抓住，弯腰趴在她辅导他的桌子上！！学生已经受够了数学，认为是时候让他们俩一起做点更有趣的事情了！！然后他把她绑在门上，塔蒂 (Tatti) 发现自己的脚踝被绳子绑住，嘴里塞着东西，手腕被绑在头顶上！Tatti has been having a hard time with a particular student of hers, he has been studying so hard but just is not gripping a certain part of his maths degree that he needs extra help with.. both tensions beginning to rise as neither one of them is getting anywhere. Tatti explaining her methods for the last time finds herself being grabbed by her student and bent over the desk she has been tutoring him on!! The student has had enough of maths and thinks it’s time they both spend their time doing something a lot more fun!! He then strings her up against the door where Tatti finds herself with rope tied around her ankles, a cleave gag and her wrists tied above her head!
