ROYD-173 My sister will teach you all kinds of things♪ My exclusive Katekyo sister-in-law, Kanna Misaki, whispers sweet words in my ear and demands raw sex.

Even though my parents are at home, my sister-in-law makes it a point to watch me study, leaving us alone. Then, whether it was to make me want to have sex or because I was frustrated, she kept whispering slang words in my ear! I reveal my true nature that I can't imagine from my appearance, and my whole body is raped as if I enjoy the reaction! The act gradually escalates and I am made to cum over and over again! Thanks to you, my grades are better.
