The wife is very strong-willed and dominates her husband, despising and looking down on him. She regrets marrying her husband who is 10 years older than her, and even thinks she would be happy to get divorced if they didn't have a child that she loves. She hasn't had sex with her husband for three years, or rather, she hasn't let him have sex with her, and she occasionally hangs out with an 18-year-old young man she met on a dating site, hiding the fact that she is a married woman with children. When her husband notices this and investigates the young man, he finds out that he is a new employee at her husband's senior's company, and asks him to help him with a plan to cuckold his wife. At first, the wife hates older men, but her body is Kokoro to the persistent raw creampie sex of a middle-aged man for the first time in a long time. Like a frustrated wife, her body gradually becomes addicted to raw dicks, and she throws away her shame and indulges in pleasure and greedily enjoys it.
