ROYD-027 The irresistible temptation from my teenage niece

My niece suddenly came from Tokyo! My mother's father (my niece's grandfather) seemed to be suddenly ill, so I decided to leave my niece at home for a while. I haven't seen her in a while, and she's gotten so big that it's confusing me. Such a curious niece about cocks, and I was old enough to give in to the temptation of my brother's daughter and have sex, seven days of life had begun! ?
