I have a beautiful younger sister with a very attractive and seductive figure. I have had perverted thoughts about her many times, but because we are siblings and I know the consequences would be serious, I have tried to control myself. One time when our parents went on a trip for a few days, it was just me and my younger sister at home. When parents go on vacation, the older brother stays home and fucks his own sister She was dressed very provocatively, wearing only a thin nightgown that constantly revealed her underwear in front of me. She then asked me to give her a massage because she felt tired. When my hands touched her body, the dark thoughts from before started rushing back, and it seemed like I couldn't control myself. My hands gradually moved towards her private area, and in the end, we engaged in incest with each other in the innocence of my still pure sister.
