Once upon a time, in a distant place, lived a father and his two young sons—Urashima Tarou. Though gentle by nature, Tarou harbored an intense sexual desire. One day, his father's mistress came to visit. As her moans echoed through the house, Tarou, who had always been curious, couldn't resist peeking in... That moment changed his life forever. In the Dragon Palace, he met Otohime—'KAORI'—a woman of overwhelming beauty and power. Their encounter shook him to his core. Her unbelievably pleasurable service and mind-blowing orgasms made him forget everything, as if the world had ended. The classic Japanese folktale is reborn here in a whole new form.
