Nonoka is a flight attendant, and her husband is Captain Shinichi. After getting married, Nonoka decides to quit her job to be a housewife and take care of her husband. Although both of them want to have children, due to Shinichi's erectile dysfunction, the chance of having sex, let alone conceiving a baby, is slim. Her boring life goes on day by day. One day, she is raped by a close student of hers. Nonoka immediately calls Shinichi, but he hangs up before she can tell him. Feeling lonely and miserable, Nonoka seeks solace at the coffee shop she often frequents. Hiromu listens to Nonoka's story, gently embraces her, providing her with warmth and safety in her weakest moment. Therefore, Nonoka willingly offers her body to Hiromu, hoping he can soothe her broken heart. Since then, they continuously meet whenever Shinichi is at work. Each time, Nonoka lets Hiromu ejaculate deep inside her body. Today, the weather suddenly turns bad, and Shinichi's schedule is postponed to another day. While buying a cake to bring home to his wife, he catches her letting another man ejaculate inside her vagina in their bathroom! Instead of getting angry, Shinichi discovers his own kinky preference, enjoying watching his wife being fucked by another man! Watching another man ejaculate into his beloved wife's vagina makes his cock harden for the first time in a long while! However, he realizes it's not good for her to have sex with strangers, so he calls his close younger brother Keisuke to come over for dinner. After a satisfying meal, Shinichi suggests a threesome to Nonoka. Initially, Nonoka refuses, but seeing how much her husband enjoys it, she feels extremely aroused and ecstatic, so she becomes more proactive. Some time later, Nonoka becomes pregnant, and both husband and wife are very happy, but deep down, they both don't know who the baby's father is... Bonus: Behind-the-scenes footage and a scene of blowjob for the assistant director.
