MKMP-518 I was fired from my company due to my brother's debt and worked every day at a convenience store... I've worn down my spirit and can easily open my legs if a man invites me in. I'm a convenience store woman who's available 24 hours a day, Sumire Kurokawa.

My sister's consumer finance company contacted her and she had to quit her job. The cause was a large amount of debt owed by her younger brother, who lives with her. However, in order to pay off the debts her brother has incurred, the older sister works like a robot at a convenience store. His mind gradually wears down due to constant debt and fatigue, and when everything becomes insignificant, his sister becomes a man who has sex with anyone, anywhere.
