Once a week, Minami began English lessons to support her husband's career. Amid their busy married life, she starts looking forward to the time spent with her instructor, Lucas.

Her first affair, her first experience with a huge black cock—pleasure that reaches deep inside her, hitting spots her husband never could, shattering her rationality. The intense creampie orgasms make her realize there's no going back.
