It was decided that the new employee, Adachi, would travel together with his boss, Saejima, who he disliked due to his habitual sexual harassment. Adachi, who was in a relationship with his senior, Yoshida, within the company, expressed his dissatisfaction but was placated and reluctantly went on the business trip. At the destination, Adachi accompanied Saejima for a late-night drink and was drugged. When he woke up, Saejima was in front of him, consuming his body... Initially resisting, the moment he was penetrated, a wave of pleasure rushed through his entire body. Their physical compatibility was perfect, and they continued to climax all night long.
