Natsume-ke no Nichijou

Natsume Yuu 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.
