This is Mayu's fourth appearance in "Otona no Binihon". She is a strange older sister who thinks about lewd things all year round and releases her sexual desire with her younger brother's dick. She makes an extremely obscene sound as she devours the dick, handles it with her beautiful big breasts, enjoys seeing her younger brother's face in agony, and straddles the dick without a condom in rodeo cowgirl position. She's a naughty girl who loves creampies and unilaterally shakes her hips to expose her ahegao face.
