A woman who can't refuse unreasonable demands while holding her weakness gives me the pleasure of pouring out my sexual desire while giving me a disgusting look! Erika, an active female college student and tutor hired for her son's advancement, is my favorite beauty. When I learned that her parents needed a lot of money to undergo surgery, I decided to hide her ulterior motives and lend her the money. But after her first surgery, she needed treatment again and needed money again. In exchange for the weakness of debt, I hit the sexual desire that had accumulated.
