Young wife Asahi married an older, financially stable man. Although her husband wants children, she feels unsatisfied with their refined but unexciting sex life. One day, she comes across the term "egg donation" in a magazine and devises a new plan. Choosing men who match her ideal type, she begins an affair-filled journey—luring handsome instructors, brilliant young scholars, and even wealthy corporate heirs, indulging in breeding sessions and creampie sex with each of them.
