Aunt Mio had a fight with her husband and ended up living at Keisuke's house for a while. To Keisuke, Mio was an object of admiration, and he harbored romantic feelings for her. He lived in a state of excitement, captivated by the valley between her large breasts. One day, Keisuke found Mio's panties left in the bathroom and couldn't help but masturbate, but Mio had witnessed it. The free-spirited Mio went to Keisuke while he was taking a bath late at night, gently stroked his penis, and then inserted it into her vagina.
