EKDV-635 A holiday alone with my cute, smiling sister who silently asks for my body every time we meet. - Chiharu Sakurai

One day, my father remarried. - The other party's stepchild 'Chiharu' came to the house as a sister-in-law. - One day, my parents went out. - Alone with Chiharu. - The two of them are more aware of each other than usual. - And without any conversation, they desire each other's bodies in silence. - From that day on, my sister and I began a relationship in which ``as soon as we saw each other, we silently sought each other's bodies.''
