Overview

Due to my parents' remarriage, I suddenly started living with my younger sister today. At first, I just thought she was cheeky and cute, but then she started to tease me as I was more timid... "Hey, big brother! Let's give you a twitch in the morning!" My sister simply teased my nipples. Because I love her...I got so horny with my sister who keeps playing with my nipples that I couldn't take her back, so I had no use worrying about it, so I fucked her so hard for three days.
