AMBI-149 3 Days Of Being Alone With My Younger Step-sister Who Isn't Related By B***d! We Used Our Time Well To Enjoy Nothing But Sex! Ichika Matsumoto

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!
