It was exactly six months ago that I fell in love with my wife's younger sister, Rui. She has a petite and adorable smile, large breasts that don't seem to fit her body, and a sister-in-law that I want to hold. However, Rui started dating Hayato, a junior at my wife's company. Nevertheless, my feelings for Rui continued to grow... One day, my wife and Hayato decided to go on a five-day business trip overseas. This was my chance! I called Rui and took her, trained her while she cried and screamed, and recorded our love on video.
