DVAJ-164 My sister comes into the futon without permission Nanami Kawakami

The entire story is from the younger brother's perspective. An incest story between me and my sister! That day, I hugged my sister to cheer her up when she was crying, and she kissed me... ever since then, it's like I've been used as her boyfriend. After all, this kind of relationship is no good! Even though I thought so, my lower body reacted violently. My sister crawled into my futon again today. Lately, I've been taking it for granted in both my room and the bathroom.
