I was an only child, but suddenly, three older sisters entered my life—all because my father remarried. The eldest, Hibiki nee-chan, is slender, beautiful, and gentle, taking meticulous care of herself every day with beauty tools, wrapping my heart in warmth. The second, Arisu nee-chan, is a busty blonde gyaru with a stunning figure—her large breasts and round, plump ass instantly captivate anyone who sees her. The youngest, Yumi nee-chan, looks amazing in a uniform, tall and always smiling, giving off a comforting, reassuring presence.
For some reason, my sisters keep gathering in my room. And surprisingly, they're all naturists—immediately stripping naked the moment they come home. Their nude bodies are incredibly stimulating, making me instantly hard. And whenever I get hard, they're all delighted. Yumi nee-chan, Arisu nee-chan, and Hibiki nee-chan take turns waiting their turn, all hoping I'll stay hard for them. I feel a bit embarrassed, but at the same time, incredibly happy. My days with my sisters are thrilling, warm, and deeply fulfilling—a truly special time that fills my heart.
