ADN-581 _The irresistible charm of a sister-in-law

The destination of my business trip this time was quite close to my brother's house, so I chose to stay at his house to save costs for the company. We hadn't seen each other for a long time, so my brother agreed because this was a good opportunity for the two of us to review old memories. His wife, Ayaharu-san, after not seeing her for a long time, was so used to living in the countryside that she never wore a bra, nor did she care if she was seen. I live in the city so my concept of life is different. I can't stop thinking about Ayaharu-san and in this countryside, besides the work assigned by the company, I don't have anything else to do. Dark thoughts began to take over my mind and I gradually couldn't control my behavior with my sister-in-law anymore..
