Mei Satsuki was always quiet and reserved, but in truth, she harbored special feelings—just for me. Deeply sexual, she had secretly played around with me since childhood. Our parents never noticed, but even now, she can't hide her desire. One day, my grandfather got injured, forcing our parents to return to their hometown. Mei didn't want to go, and they hesitated to leave her alone. So they decided to have me take care of her. Left alone together, we crossed the boundary of our usual relationship and spent our first night together. In the silence of the house, we finally confessed our true feelings and gave in to our passion.
