On the day my parents left the house for a memorial service, I was alone with my younger sister, who was about to move, for the first time in a while. Looking at her defenseless sister, who is proud of her family because she is cute and good at studying... I can't resist her desires and forcefully commit her sister... Then her sister consulted that she may actually have a stronger libido than others. After that, until the day she moved out of the house, I had sex with her sister over and over again... This is the record of that day.
