Yu's husband is currently unemployed, despite applying for jobs everywhere but still not being accepted anywhere. The meager income from Yu's part-time job is not enough to support the family. Rent has not been paid for six months, and the landlord suggests using Yu's body as payment. At first, Yu refused, but with no money, they are now facing eviction and the only option left is to sleep on the streets. Wanting her husband to focus on work without worries, Yu decides to offer herself to the landlord to reduce the debt. Each time they have sex, one month's rent is deducted, but if he doesn't ejaculate inside her, it only counts as half. Yu continues to serve the landlord sexually. His huge penis and skilled techniques quickly conquer Yu, giving her pleasure she had never experienced before. In this way, Yu quickly "pays off" the entire rent. Yu's husband finds a job, so she no longer has a reason to continue with the landlord. To celebrate her husband's new job, the landlord invites them both to dinner. Yu's husband drinks too much and falls asleep at the table. Taking advantage of the situation, Yu seduces and has sex with the landlord while her husband is right there. Despite the landlord saying she doesn't have to do this anymore, Yu can't control herself. She wants to have sex and experience the pleasure that only he can provide.
