Hatsune Minori makes her debut as the exclusive star of the highly popular series' second installment. Exuding irresistible charm and sensuality, she takes part in an extreme challenge where both she and her male partner abstain from masturbation and sex for an entire month. After this period of prolonged abstinence, they secretly meet in a hotel room. With her feminine desire pushed to the absolute limit, her pent-up lust explodes the moment they reunite. They engage in intense, relentless sex, devouring each other's lips and bodily fluids with desperate passion. Again and again, they climax—ejaculating, reaching orgasm—yet they cannot stop. What follows is an ultimate erotic experience: hours of non-stop, consciousness-blurring orgasms, as their insatiable hunger drives them through an unending marathon of pleasure.
