Sister's Crime Diary - Ayaba Miori GVG-917

My younger sister, Miori, has to live in a small new house, sharing a room with her younger brother. Having reached the age where she's interested in men's bodies, Miori undresses her sleeping brother and carefully examines his penis. Furthermore, while he's washing himself in the bathtub, she plays with his penis and makes him ejaculate. Because of this behavior, her brother also becomes sexually aroused, and this time, he attacks Miori while she's asleep!
