Newly hired employee Miho is inexperienced and frequently makes mistakes at work. To relieve her stress, she turns to masturbation, and has developed the habit of noticing male coworkers' crotches even during office hours. Her boss, Fujikawa, notices her behavior and uses her work errors as an excuse to seduce her. Though Miho initially resists, the suppressed desires within her body begin to awaken, causing her to lose herself in pleasure and forget her former self. Fujikawa becomes increasingly captivated by how the situation unfolds.
