I have an idol I admire. She is a beautiful girl named Wakaba, who has an
angelic smile that is said to be seen once in a thousand years. But when my
parents remarried, Wakaba became my younger sister… I was happy for a
moment, but at home she was always cold and tsundere. My admiration was
shattered, but then I accidentally saw Wakaba masturbating, and from that
day on, I started using her as a vibrator to relieve my idol’s sexual
desire…
