I fell in love with my wife's younger sister, Akari. She is a cheerful, charming sister-in-law who is loved by everyone. I want to hold her young, growing body tightly... However, Akari is dating my wife's colleague, Eiji. But my feelings for Akari continue to grow... One day, my wife and Eiji are going on a company trip and will be away from Japan for five days. This is my chance! I called Akari and raped her, thoroughly training her while she cried and screamed, and recorded my love for her on video, which was enough to drive me crazy.
