Kinoshita and his wife run a convenience store. Due to a shortage of labor across the country, finding part-time workers has been extremely difficult. As a result, Ririko had to start working at the store even though her husband promised not to make her work there. With not enough people to look after the store, Ririko's husband is almost always at the store, leaving little time for the two of them. Ririko's sexual desire is increasing day by day, so she has to use a dildo to satisfy her own cravings. One day, Ririko caught a boy stealing from her store. The boy seemed timid and was being bullied by his friends, forcing him to steal. Seeing this innocent boy sparked a desire in Ririko to take away his virginity. She could forgive the boy for his theft on one condition, that he pleases her. Over time, the boy grew up and lost his innocent look. Ririko lost interest in him and started looking for a new prey.
