A good-natured husband, Shinji, recommended his brother, Yuichi, who became penniless due to debt, to live together, and decided to live with his wife Sora for the time being. Sora was uneasy about the savage and rough Yuichi. One day, Yuichi attacked me while I was taking a nap. Yuichi plays with Sora on a daily basis as she suffers without being able to tell her husband that she was raped by her brother-in-law. However, the rough caress of the brother-in-law and the thick and hard meat stick gradually gave the sky a pleasure that her husband did not feel.
