Despite being the president of a major corporation, Machida harbors dissatisfaction with her sex life. As she grows older, her libido continues to rise, while her husband's desire diminishes day by day. Their monthly one or two sexual encounters follow the same routine, progressing mechanically and emotionlessly, like a mere chore. Feeling unfulfilled by this monotonous routine, Machida decides to seek new excitement by appearing in an adult video. In the reunion chapter, the moment she undresses, thick pheromones fill the air, enveloping the entire room in a deeply erotic atmosphere. Lost in pleasure, Machida forgets her shame, pressing her body tightly against the man, craving his touch. She then takes the man's penis deep into her throat, driving them both toward ultimate ecstasy.
