Natsuki Kisaragi's older sister, whom she admired, became her younger brother's sex slave
Natsuki-chan, my cousin who is three years older than me. Ever since we were children, she took care of me and my younger brother like a real sister. I had always had a faint crush on Natsuki-chan...I met Natsuki-chan again after 3 years after getting a job. Her younger brother was still a shitty kid who was easily spoiled by Natsuki-chan. The purpose of this trip home was to confess to Natsuki-chan, who I have never forgotten...
