On the day my parents were away from home for a memorial service, I was alone with my little sister who was about to move out... Seeing the defenseless appearance of my little sister, who the family was proud of as being good at studying and cute... I couldn't resist my desire, so I forced myself. I end up raping my sister... Then, her sister tells her that she may actually have stronger sexual desires than other people. From then on, I had sex with her sister over and over again until the day I left home for her move... This is a record of that day.
