Rin, who had just come from the countryside. She is plain and shy, easily pushed around, and can't refuse when someone above her insists on something. One day, she saw a help wanted sign at a nearby convenience store while hesitating, the manager called out to her and hired her on the spot. Even in the convenience store uniform, she couldn't hide her large breasts and fell into the manager's trap. Every time she goes to the convenience store, she is subjected to lewd acts by the manager she hates, but she can't quit her part-time job. Her reason is... 'Just touching myself isn't enough, this nipple has turned into a greedy one.'
