Miyu is gorgeous, brilliant, and frighteningly competent—a flawless boss whose private life is a complete mystery. Then she unexpectedly invites her subordinate out for drinks. Once alcohol loosens her up, she gets touchy, starts talking dirty, and asks whether he has been sleeping with anyone lately. He takes her to a hotel, where her hidden sex drive erupts. The supposedly perfect boss cannot stop, demanding raw sex and creampies as their workplace hierarchy turns completely upside down.
