My cute little sister "Ichika" has always clung to me since we were kids. Ever since she was crawling around as a baby, her affectionate, needy personality never changed. Even now, she stays close to her big brother, always wanting to be together. But recently, her body has matured from a child's into a woman's, radiating a completely new kind of allure. And then she whispers to me: "Onii-chan... are you about to cum? It's okay... you can come inside me. Fill me up deep inside..." Her words send my heart racing.
