GVG-917 Sister Criminal Diary Miori Ayaba

My sister Miori has to live in a new house with a small number of rooms, sharing a room with her younger brother. Miori, who is at an age where she is interested in men's bodies, takes off her sleeping brother's clothes and carefully observes his dick. Furthermore, while washing his body in the bath, he plays with his dick and makes him ejaculate. And as a result of that act, the younger brother also had a sexual awakening, and this time, the younger brother attacked Miori while she was sleeping!
