Ayaka, a perfect workaholic OL, had one problem. Her nipples were abnormally weak and hypersensitive. One day, her slightly clumsy subordinate Ikura found out about Ayaka's sensitive nipples. When Ayaka's nipples are touched, she breathes cutely. This sight ignites Ikura's lesbian desires, and she continues to play with the nipples in the office. Gradually, Ayaka also gets aroused, and the two start playing with each other's nipples in the office.
