[Reducing Mosaic]JUR-522 "If it's just masturbation, then it doesn't count as cheating..." During the business trip without my brother, my sister-in-law is a 'masturbation addict,' and I am the 'exclusive AV actor' for Kana Hishibe Kana Hishibe

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.
