Due to her husband's erectile dysfunction, his wife, Iori, had no sex life and experienced painful days. The father-in-law, knowing the couple's suffering, felt guilty about not being able to see his two grandchildren, so he bought aphrodisiacs for them. My father-in-law tried it by accident, but the effect was amazing! As soon as I got hard, I became full of energy, and even Iori, who was taking care of me, noticed. Iori, who had been abandoned for a long time, fell in love with an acquaintance's full-bodied demon Ji Po, and began to sexually manipulate him under the pretext of nursing care.
