Mathematics

The class is being taught by Miss Chai. Age probably close to 40 years old, though no one really make the effort to find out, she is an epitome of a MILF, If only she is a mother or at least married.

But not to stereotype people, but for Miss Chai, being a mathematics teacher is probably a life calling. Slim and slender, a body typical of a Chinese, with a serious expression almost all the time, the still single and unmarried teacher is known for being inflexible, or just a stick-in-the-mud.

While you're not beyond her reproach due to various screw ups during your class, you don't really mind since you're very much self aware of your faults. Also, while she isn't the most beautiful teacher, that belongs to Mrs Smith, and the most voluptuous is Mrs. Baker, Miss Chai has a nice smile, nice enough that you have developed a crush on her.
