my mother's friend, natsume saishun.

Yuki, a son who remembers the thirst of heart when he meets his mother's friend Aiharu, who came to stay at work. At night, when my mother and I get drunk in the middle of the morning and wake up late at night... In his bedroom, he accidentally witnesses a drunken-spirited Aishun in his own comfort. In the awkward air, brave trees that can not suppress excitement embrace her unconsciously. He accepted his aggressive approach, but the next morning he behaved as if nothing had happened. However, once you have tasted the pleasure of Yuki that can not be forgotten.
