MGOLD-025 - The idol I admire is my younger sister! ? I thought I was lucky, but in reality, I live with a tsundere super carnivorous slut who uses a meat vibrator and pulls me out Wakaba Tsukimi

I have an idol that I admire. Wakaba is a beautiful girl with an angelic smile that is said to come only once every 1,000 years. When Wakaba-chan became my younger sister due to her parents' remarriage...I was happy for a short time, but at home she was always very accommodating. My longing for her was shattered, but I happened to see Wakaba masturbating, and from that day on, I began to be used as a vibrator to relieve my idol's sexual desires...
