My wife, Fuyumi, has a younger sister named Ruka. She is a young and cute college student with an innocent smile and a well-developed body that is very attractive. Ruka is dating my wife's subordinate, Toru, but I have had feelings for her for a long time... Every time I see Ruka, I can't control my sexual desires... One day, during a company trip, Fuyumi and Toru went to Kumamoto. This was an opportunity; I called out Ruka, raped her, and repeatedly ejaculated inside her both day and night while training her. I also recorded these memories on video.
