OBA-322 - My relative Aunt Miori secretly seducing me

My mother went on a business trip for a week, so my father and I stayed at our relative Aunt Miori's house. I discovered a shocking secret between my father and Aunt Miori: they were having an affair. Having admired her since childhood, I was devastated. That night, while secretly watching her being intimate with my father, our eyes met while she was in the heat of the moment.
