A sex movie of Yuna Shiina’s adultery. Marrying a weak and impotent husband was probably one of the worst choices in Yuna Shina’s life. She was the complete opposite of him, a free-spirited, easy-going woman with extremely high sexual needs. Because of this, their happiness was increasingly broken. Her husband only knew how to focus on his work while Shina secretly went out to have affairs with other tall, strong men. Although she had made the wrong choice from the beginning, she thought this was her chance to correct her mistake. If her husband was useless, she had to ask someone else to take care of his physiological needs!
