Yuu Natsume is a blessed boy—his two older sisters are beautiful beyond belief. With short, purple hair and irresistible curves, Mayaka is a tomboy-ish male magnet, able to make any man stare with overwhelming desire. On the other hand, Asahi is a mature and mild-mannered blonde with large breasts. Her somewhat introverted personality and cute appearance pique the interest of any who catch a glimpse of her. Though they could have any man they might want, these two belles only have eyes for one, reserving their uncontrollable love for their brother.
