A sudden torrential downpour leaves a male boss and female subordinate alone in the office, unable to go home. The male boss is secretly annoyed at his female subordinate, who has better capacity than him and is good at getting by in the office despite being young. When her clothes get wet from the rain and her underwear becomes visible, he becomes aroused and violently rapes her. The female employee is defeated by force and is repeatedly fucked, gradually becoming aroused by the humiliating orgasm she is made to have. The two of them have an abnormal relationship and continue to fuck until the morning.
