Yukine, 30 years old, married for 5 years. Influenced by her travel-loving parents, she joined a travel agency. She met her husband, a medical clerk, while traveling and married him at 26. She quit her job to focus on getting pregnant but gradually her husband's erection became incomplete, leading to a sexless marriage. Concerned about her husband's health, she learned that he had a cuckold wish. Confused by her husband's desire to appear in AVs, she ultimately accepted his unusual fetish for the sake of their future.
