My sister suddenly came to my house and said, 'You must be tired from work! Relax by looking at my panties!' and then showed me her panties. I couldn't help but look, but I quickly regained my composure. While I was in the bath, my naked sister appeared saying, 'Let me wash your back.' Her developing body made mine stir! Boobs squishy-squishy, butt pat-pat! I can't hold back anymore! I had sex with my sister!
