During the summer vacation, I returned to my hometown after a long time and found that my nieces 'Kotone' and 'Rin' had come to play. The two of them showed a slightly more mature appearance than when I last saw them a year ago, but their innocent way of clinging to me saying 'I love you, big brother' hasn't changed. Their pure smiles and slender bodies... their budding chests in the midst of puberty... my nieces who have entered puberty have stolen my heart and body...
