MESU-109 Punishment of the sexually crazy female department head

I am a new intern at the company and Ms. Seo Reiko was my senior during those working days. Even though she is 40 years old, Seo Reiko is still unmarried and still looks very beautiful. That day, I was assigned by her to meet a customer and satisfy her to get a contract, but I failed to complete it. Yes, I was scolded by her a lot... She usually looks very gentle but when she's angry I'm very scared but for this mistake I will have to suffer her punishment. I thought I would be severely punished but no, I know the reason why she is 40 but still unmarried is because no one can stand her lust. Seo Reiko is as lustful as the actresses I often watch and My punishment is to serve her sexually until my anger subsides...
