My aunt Mio quarreled with her husband and decided to live at Keisuke's house for a while. For Keisuke, Mio was a longing person and had a favor as the opposite sex. Keisuke finds Mio's pants left in the bathroom while living in the cleavage of big breasts. I masturbate involuntarily, but Mio witnessed it. When Mio, who has a free-spirited personality, comes to Keisuke who is taking a bath at midnight, gently squeezes Keisuke's Ji-Po and inserts it into Ma-ko as it is.
