Shattered wine became the catalyst for the incident. An office lady collides with a man on the street, causing the wine he was carrying to fall and break. The man forcibly drags her away on the spot. What awaits her is punishment to defile her body as reparation. Subjected to torment by electric sex toys and penetrated by real men's erect cocks, the office lady's mind is swallowed by waves of pleasure, sinking to the depths of a sadistic sea. Then, her friend—an office lady as well—is summoned. The purpose is clear: to subject her to the same cruel fate.
