It's been a year since Akina began dating Naoki. He's a terrific guy but there's only one problem: they've never been successful in bed. One day, the door to Naoki's room hasn't been closed properly, and his brother, Tomoki, sees them in yet another failed attempt. From that day on, Tomoki starts giving Akina lessons in sex. A collection of red-hot passion that includes titillating stories based on true ones from readers, which include a case of mistaken identity (sex with their boyfriend's twin brother!), a passionate date between two couples on an overnight trip to a spa, and more.
