MAX-A exclusive actress Rin-chan's sixth work is a lewd and tsundere little sister setting, a completely subjective work!!! One day, my parents suddenly went on a business trip overseas, and I started living together with my little sister Rin just the two of us. Actually, we have a secret incestuous relationship that our parents don't know about, and every day we are seduced by this tsundere little devil sister!!! A dreamy, sweet, lewd cohabitation sex life from the brother's perspective. Hey... Big brother, let's do it... Rin really, really likes you!!
