[AMBI-159] Three days alone with my playless sister! I had sex all the time! ! Rin Asahi (Censored)

My mother remarried and I have a brother who is not related by blood. At first, I was worried if I could get along with my older brother, but now we get along so well that it's more than brother and sister! I usually steal my parents' eyes and do naughty things with my brother, but my parents had to leave the house for 3 days due to a memorial service... I'm really looking forward to three days with my brother!
