My father married a very beautiful woman named Misora five years ago. My father, who is completely in love with Misora, is flirting with her wherever she is. But I knew. Misora-san isn't satisfied... Since then, I started to feel the immorality of wanting to do naughty things with Misora-san. Then, when we were alone, I took Misora-san's body as she was washing dishes.
