On a hot summer day, I came to Tokyo from my hometown to look for a job. Because I still don't have a job, I stay at my brother's house. My sister-in-law is Julia, she is really beautiful, and she has always treated me well. Because she wants to preserve her beauty and benefit her health, she never turns on the air conditioner. Her body was always drenched in sweat, her nipples were clearly visible through the delicate shirt without any underwear. While living together, I knew that she was not satisfied with her brother, and she always saw her charming body clearly visible in front of my eyes, which made me unable to control herself and rushed to take over her body... Then we started this forbidden relationship, but then my brother found out. I was kicked out but when I came back to get my belongings, my sister and I had sex many times before I moved to another place...
