I went back to my parents' house for the first time in a while. My little sister is so cute I want to brag about her, and she seems to really like me. She treats me like she's her boyfriend. I couldn't help but get an erection when I saw her grown-up body. I thought my little sister would find it gross, but she started to play with my dick with her devilish hands! No! This is going to turn into incest! As if she sensed my feelings, my little sister started to shake her devilish hips and inserted my bare dick before I knew it! Wait, wait! I can't stop. This naughty and extremely pleasurable brother-sister sex has begun!
