I returned to my brother's family home. Then, my brother suddenly decided to go on a solo business trip. My brother's wife, Hibari-san, who is pure and cute, was left all alone. One day, Hibari-san came to my room. She seemed to know about the shared fetish videos that my brother and I had watched... Before I knew it, there she was in front of me, looking erotic. It seems that guided by my brother, Hibari-san had awakened into a full-fledged slut. From that day on, to distract herself from loneliness, Hibari-san started relentlessly blaming me and engaging in her slutty sex.
