JUR-522 If it’s only self-pleasure, it doesn’t count as cheating… During a business trip when my older brother is away, my sister-in-law, Kana Kusakabe, has a self-pleasure habit, and I’m her exclusive fantasy material.

After graduating from college, I couldn’t find a job, so while working part-time in Tokyo and studying for a qualification, I ended up staying with my older brother and his wife. My older brother, who had always been strict and serious, works for a top construction company in Tokyo and seems busy every day. Supporting him is his wife, Kana. Unlike my brother, she is a little gentle and laid-back, but very kind, and the couple seems to get along well. Then, just as a week was about to pass since I started staying with them, my brother suddenly had to go on a business trip and would be away from home for two or three months.
