When I returned to my parents' house for the first time in a while, my younger sister Azusa greeted me, still clingy and affectionate towards me. She does have a tsundere-like way of speaking and acting, but she quickly becomes affectionate again. But what's different from before is that she's grown into an adult body! Her breasts have gotten bigger and look softer, and her ass is plump and looks delicious! I couldn't resist and hugged Azusa and had sex!
