Nagi is a manager who is good at her job and is loved by her subordinates. She is sometimes strict in educating her subordinates, but she has a secret that she can never tell anyone in the company. Haa...haa...welcome back, onee-sama. When I got home, I was greeted by one of my subordinates, Mai, who had a necklace around her neck... The relationship between the superior and the subordinate is reversed day and night. During the day, he is a serious elite and a normal employee. At night, a perverted bitch and a de S lesbian. The SM relationship between the two is immersed in endless pleasure.
