Sae's nephew by marriage, Koji, comes to stay at her house while job hunting. One day, while cleaning the bathroom, Sae notices a shadow in the window and turns around in shock—Koji is sniffing her panties. To cheer him up after a disappointing job interview, Sae performs masturbation in her underwear, climaxing three times. Using her voluptuous breasts for titfuck, handjob, and blowjob, she milks him of semen, boosting his confidence and helping him land a job. On the night he secures employment, sex awaits between Sae in her lingerie and Koji. Ultimately, they reach a forbidden conclusion: creampie and pregnancy.
