In the IT company located in Shin-ku district, there are numerous reasons why employees do not quit despite being overworked and under constant pressure from management. One such reason lies within the support system provided by the young female accountant, Ayanase, whose unassuming appearance belies her incredibly sexy body with an amazingly huge pair of breasts. She has become indispensable due to her inability to refuse any request or task given to her, making her the perfect candidate for sexual relief duties. As a result, she finds herself constantly servicing exhausted colleagues late at night with passionate blowjobs and pizza fucks, offering them much-needed release from their stressful jobs. Her catchphrase? "Just let all that work stress out on me so you can feel refreshed."
