Financial Slavery to a Girl in a Sailor Uniform and Swimsuit

There is an academy in a certain city where the uniform is a sailor suit and a school swimsuit. Karen, a student at this eccentric academy, finds a man with a strong sexual appetite and asks him for some sexual gratification. Not content with that, Karen tames the principal at school, turning him into her financial slave. She makes him lick her shoes, makes him watch her have sex with another man, and even forces him to lick used condoms. Therein lies happiness for this masochist! (Source: Fakku!)
