Sasakura Aya, who joined the company from a listed company in the sales department, is beautiful, competent, and well-liked by the president. She has a high level of pride and usually looks down on the sales manager, Narusawa, who is incompetent at his job, and secretly calls him incompetent. Irritated by Sasakura's haughty and rebellious attitude, Narusawa decides to take her as a substitute on a sudden business trip requested by the president. Wanting to strike back, he buys an aphrodisiac online and, claiming that two rooms were unavailable at a hotel, forces her to share a room with him, setting up a despicable trap... The old-man boss explodes in anger, and in the shared room he insists on, he has sex with her until the morning, relentlessly cumming inside her. "You're so insolent," he says, and later in the office, all the men from the sales department gang-rape her!!!
