BBAN-528 A mischievous junior who missed the last train disrupts her routine, and her body, made more sensitive by abstaining in a shared room, is teased until she repeatedly reaches intense peaks. Sex-crazed female boss Aya Nanjo and Himari Kinoshita

Aya, a career woman working at a major company, is well liked within the office and always wears a smile, so people around her see her as a calm and gentle person. In reality, however, she has such an intense libido that she can barely keep herself together unless she takes care of her urges in private. One night, her junior coworker Himari, who missed the last train, suddenly shows up at her place and ends up staying over. Aya had been holding back her urges due to this unexpected shared-room situation, but as time passes she begins to lose her composure and starts using her junior coworker’s belongings to satisfy herself.
