[MIAA-327] My beloved sister, who I thought was still a virgin, was being made a made-out toy for all my friends. 1 chisa Matsumoto

When I was little, my parents remarried and my younger sister, I, adored me and missed me. I was friendly and friendly with my friends, and I thought it was smiling, but I never thought I was repeating play in a place I didn't know! My lovely, my only sister! Still, I turned to goodness that my sister was indifferent to sex and I was against it! "Let's have an older brother, too" My sister called me so, and something of the emotion in me changed.
