On a hot summer day, I went from my hometown to Tokyo to look for a job. Because I still don't have a job, I'm staying at my brother's house. My sister-in-law is Julia, she is really beautiful and always treats me well. Because of preserving her beauty and wanting to benefit her health, she never turns on the air conditioner. Her body was always drenched in sweat, her nipples were clearly visible through the thin shirt without any underwear. While living together, I knew she was not satisfied with her brother, and I always saw her seductive body clearly visible before my eyes, making me unable to control myself and rush to take over her body... After that We started this forbidden relationship, but then my brother also found out. I was kicked out, but when I came back to get my things, my sister and I had sex many times before I moved to another place...
