Ayaka, a career woman who perfectly handles her work. She had one worry: that her nipples were extremely sensitive and she had a super sensitive constitution. One day, her weakness for nipples is discovered by Ikura, a slightly clumsy subordinate of Ayaka. Ikura, whose lesbian heart was ignited by Ayaka's cute moaning when her nipples were touched, continues to play with her nipples in the office. Gradually, Ayaka also becomes aroused, and the two begin to play with each other's nipples in the office.
