JUR-522 - “If it’s just masturbation, it’s not cheating…” While on a business trip without my brother, my sister-in-law is addicted to masturbation, and I’m a wanker just for Kana-san Kana Kusakabe

After graduating from university and unable to find a job, I decided to stay with my older brother and his wife in order to work part-time in Tokyo and obtain qualifications. My older brother, who has always been strict and serious, works for a top general contractor in Tokyo and is busy every day. The person who supports such a busy brother is his wife Kana. Unlike her older brother, she is a little quiet, but she is very kind and seems to get along well with her husband. One day, a week after I started living here, I suddenly had to go on a business trip and be away from home for 2-3 months.
