Three years after getting married, my sister came home for the first time in a long time. My brother, who still lives at home, was dumped for being "bad at kissing" and is heartbroken... When I met my sister again after a long time, she was prettier than before. I wonder what kind of kiss she has... I'm curious about her lips... I kiss her without permission, hoping to get her to teach me "how to kiss well"! I got so excited that I even inserted my dick and the brother was so excited about our first sex! The next morning, I thought she would definitely get angry, but instead, my sister suggested that we practice kissing...
