Asuka, a member of the track team, accidentally witnesses her older brother sniffing his shoes. She often lost her socks and gym clothes, but her pervert brother, who has a penchant for smells, used them to masturbate. The older brother opens up and begs him directly to let him smell his body after practice! Although she looked embarrassed, she pressed her sweaty armpits and soles of her feet against her brother's face.
