Office lady Hombo has enjoyed masturbation since her third year of middle school, starting with a magazine insert. She secretly experimented with different techniques, hiding it from her parents. Although she now frequently has sex with her boyfriend and casual partners, she still considers masturbation a separate necessity and continues doing it daily without fail. Today, she's ready to go. Meanwhile, Azuma from the administrative department is married, but her husband's sex life felt repetitive and unsatisfying, leading her to develop a casual relationship with her direct supervisor. It seems he's also involved with other female coworkers, and she often finds herself seduced whenever she's feeling down at work. Completely enchanted by her boss's sexual skills, she feels far more satisfied with him than with her husband.
