I am a man. When I was 7 - 13 years old, often fought with my sister. She is three years older from me. Sometimes as sibling we hated. It was a brutal fight NHB. There not was only biting and attacking the eyes. We fought fiercely incredible. Our parents rebuked us for this reason and sometimes they were beating us. When I was 14 years, we were best friends. That is until now. When I was 14 - 16 years we wrestle. It was exciting for her and for me. We wrestle often but twice she was only in thong and sexy top and I was in pants. Sitting on the face of a defeated rival was something normal for us. My penis has grown stiff, and his naked head came out of the pants top. I still remember my sister's pussy smell and sight of her labia before my eyes in high schoolgirl pin. Perhaps she remembers the smell of my balls when I win. We were so sweaty. We were deviations, but it's okay, because we did not harm anyone. It was a secret between us.
