Despite having a good marital relationship after eight years of marriage, the ERICA couple only have sex a few times a year. The husband is indifferent about it, and the wife feels physical longing, which the husband also notices. However, due to monotony and work busyness, they struggle to get aroused, leading them to think about ways to please each other and get excited. The husband decides to act on his desire to watch his wife being intimate with someone she doesn't like. After much consideration, he chooses his wife's childhood friend and a colleague's spoiled son for the task. Initially, the wife refuses, but eventually, she reveals her lewd side.
