My Brother Is My Onahole Pet #6. Airi-chan Airi Natsume

Beautiful black-haired girl Airi spends her days shut away at home. Watching her closely all along is her lustful older brother, currently a ronin student. He secretly spies on Airi as she masturbates in the bathroom or brings her boyfriend home for sex. One day, he sneaks into her room planning to have his way with her at night, but gets caught. From that day on, he becomes his sister's sex slave, forced daily to perform cunnilingus like a routine. Blood may be thicker than water, but in this case, the brother's desire for his sister is something far beyond ordinary.
