Episode :
A 16-year-old named Naoki Oikawa has developed an addiction to masturbation. One day, while indulging in his usual activity, he notices that his erotic magazine starts to emit a glow, and suddenly, Naoki finds himself transported to a fantastical realm. He discovers himself in the company of three female adventurers who introduce themselves as the swordswoman Filia Shiora, the priestess Tiane Rutheim, and the elf Llusse. They inform Naoki that their world is on the brink of destruction due to the revival of the Demon King, and the only means to avert this catastrophe is for him to harness his unique ability—by providing his semen to the three girls to significantly enhance their powers. Naturally, the young hero consents to join their quest, and thus, his erotic adventure commences.
