Mio argued with her husband so she decided to live at her sister's house for a while. It had been a long time since Mio had seen her aunt, and his deeply hidden desires began to surface. When Mio finished bathing and forgot her underwear, Keisuke used them for masturbation. Unfortunately for him, Mio discovered it. Not only was she not angry, but that night, Aunt Mio even bathed with him, gave him a handjob, and let him enjoy the beautiful body he always dreamed of.
