After returning home after a long absence, I was reunited with my niece Rin, whom I've always cherished like my own daughter—her presence deeply stirring my heart. Still newly awakened to her sexuality, she radiated an innocent, pure charm that naturally drew her uncle to her. Her radiant smile and youthful, supple body melted my heart like summer sunlight. No matter how hard I tried to stay rational, her overwhelming presence shattered my restraint, consuming me with uncontrollable desire. During the brief summer vacation, I passionately claimed her body, savoring every inch of her completely.
