A reliable older sister figure among the sales department employees, especially popular among young staff members like Matsumaru-san. However, she consistently refused requests for filming due to her strong guard. So, we proposed that she work part-time at our company doing slightly naughty tasks alongside her regular job! We successfully captured her lewd acts! This 27-year-old OL had not had sex in over two and a half years since devoting herself entirely to her career. The gap between her chaste appearance and the incredible debauchery was simply too much to handle! Note: The contents may vary depending on the distribution method.
